Gavin, Rob, Chris and the Etched team are building frontier clusters for inference, maximizing the intelligence per flop that humanity can consume.
By Sonya Huang and Abhishek Malani Published July 23, 2026Inference is on the path to becoming the largest market in the world.
If this AI dream is everything we hope it to be – and so far, the signs point to ever-increasing acceleration of capabilities – then inference will power every storefront, every movie, every medical encounter, every video game, every lawsuit, every line of code.
Today, the inference market is so obviously large that building an inference-specific system is consensus. Back in 2022, when Gavin, Chris, and Rob were still in their dorm rooms at Harvard, that bet was deeply contrarian. The result: Etched is the only post-ChatGPT-era hardware startup with production-ready custom silicon, ready to ship in 2026.
Over the past years, Etched has pioneered several research breakthroughs – low voltage inference and cluster-scale memory – each a hard-won architectural choice that drives step-change gains in throughput and latency. As the unit of compute has moved from the chip to the rack to the cluster, Etched has designed for that reality, building not just chips, but cluster-scale inference systems. Driven by these fundamental innovations, Etched’s inference system excels in throughput and interactivity on the full span of frontier models – from large sparse MoEs, to dense transformers, to alternative architectures entirely, like Mamba.
Believing this is one thing. Building it is another entirely. Novel computing hardware is among the hardest things in the world to get right, and the ground underneath is constantly moving. Models change every few weeks, context lengths stretch, attention gets reinvented, the mix of dense and sparse keeps shifting. Winning here means doing two things simultaneously: iterating fast enough to keep pace with the models, and pushing the frontier of what the hardware can do. That takes a rare kind of team: visionary enough to create the right designs, young enough to move fast, proven enough to have chips in production, and built to do this for decades, not a single tape-out.
Walking into the Etched office for the first time is like a bolt of lightning. Go in the morning or at 11 p.m. – the energy is the same, and it is infectious. Gavin and Rob are the kind of outliers both daring enough to design silicon from first principles and bold enough to knock down every obstacle in their path, and the team they have assembled matches them. We have watched them do the things that separate those who merely talk about hardware from those who ship it: standing up a live lab in San Jose to host their first racks; opening an office in Taiwan to colocate with suppliers and expedite testing; questioning every single assumption for what is possible, such as low voltage inference. “Production is the product” is the company’s mantra. Shipping is all that matters.
The company’s progress has been rapid. Earlier this year, Etched taped out its first generation chip at TSMC, making it the first post-ChatGPT-era company with a successful full-reticle A0 chip tape-out on TSMC’s leading-edge nodes. Then, in a span of just 40 days, the Etched team brought up their first cluster of chips to run inference on a wide range of frontier AI models, achieving Pareto dominant performance on industry-standard throughput-interactivity curves. Now, Etched’s earliest customers are getting access to the product, seeing for themselves the speed, throughput, and expressiveness of the system.
Etched has built a beautiful machine in Gen 1. We expect it will do very well in the market. But we are partnering with Etched because we believe they have built the rarest thing in this industry: the machine that builds the machine. This is a team that has the taste and the relentless execution to keep shipping the next generation of inference machines, faster and more ambitious each time.
The intelligence race is fundamentally compute constrained. Pushing the limits of physics to deliver the maximum intelligence per flop is both an insanely fun engineering and operations problem, and an incredibly noble mission for humanity.
We are delighted to be partnering with Etched and leading their $300 Million Series C at a $10 Billion pre-money valuation, joined by our friends at Jane Street, Andreessen Horowitz, Diffusion, and SK Hynix.

We are pleased to announce the release of Zebra 6.2.1. This patch release adds two security hardening improvements to chain synchronization and mempool verification, and fixes a Testnet-only block-template timing issue. All node operators are encouraged to upgrade.
Security Advisories GHSA-x93j-mj2f-q338: Poisoned Blocks Can Delay Download of Valid Blocks (Moderate)Chain synchronization can now immediately retry an honest block body after rejecting a body that shares its header hash, instead of waiting for a later child block to trigger cleanup. This shortens the window in which a peer delivering a poisoned same-hash block body can delay the download of the valid block. It builds on the stale-rejection fix in GHSA-8gxx-hc65-vv82. (#11052)
Thanks to @oxarbitrage for identifying this issue.
Other Security ImprovementsOn nodes with NU6.3 (Ironwood) active, Zebra now rejects underpaying and structurally invalid shielded mempool transactions before running their expensive proof verification, and disconnects peers that send transactions with invalid shielded proofs. (#11053, #11054)
Changed Testnetgetblocktemplate Timestamp Handling On Testnet, the getblocktemplate RPC no longer switches to a minimum-difficulty block template early. Zebra previously treated a template as minimum-difficulty as soon as its cur_time came within a fixed 150 seconds of the consensus minimum-difficulty threshold, clamping cur_time up to just past the threshold, which future-dated the block’s timestamp and produced spurious minimum-difficulty blocks that depress Testnet difficulty far below its equilibrium. Templates now switch to minimum difficulty only once cur_time reaches the consensus threshold itself. This is a Testnet-only, template-construction change: it does not alter block validity, and it does not change the difficulty-averaging rule that amplifies each minimum-difficulty block into a large difficulty drop (tracked in zcash/zips#1321). (#10873)
You can find the release on GitHub, crates.io, and Docker Hub. We encourage all node operators to upgrade to pick up these fixes.

Travis Kalanick, Ben Horowitz, and Erik Torenberg reunite to reflect on Uber's early days, the investment that almost happened, and why Kalanick believes the next great technology opportunity lies beyond software.
They discuss the lessons of building Uber, the value of founder-led companies, and why Kalanick spent nearly eight years quietly building Atoms before stepping back into the spotlight.
The conversation explores industrial AI, robotics, autonomy, mining, food production, and Kalanick's vision for digitizing the physical world, where software, manufacturing, real estate, and transportation come together to transform entire industries.

As governments weigh new restrictions on frontier AI models, one question is becoming increasingly important: what role should open source play in the future of artificial intelligence?
Theo Jaffee and Sofia Puccini speak with Hugging Face CEO Clément Delangue about AI regulation, open source safety, model routing, and why he believes competition—not consolidation—is essential for the industry's future.
They discuss GPT-5, government oversight of frontier models, Hugging Face surpassing $100 million in annual recurring revenue, local AI, China's open-source ecosystem, Europe's AI ambitions, and why routing workloads across specialized models could fundamentally reshape where value is created in AI.

In 2019, I found a community of people who spoke to each other differently from the rest of the crypto world. With friendliness. With patience. With something that, in a space defined by speculation and self-interest, felt almost startling: genuine empathy. I stayed because of them. I learned about the technology afterward. The fair launch. The absence of venture capital. The decade of building without institutional permission or support. The privacy architecture that does what it claims to do. All of that confirmed what the community had already shown me: that this project had been built according to a different set of values from the beginning.
This article is my attempt to look at it honestly. All of it. The parts that are painful to see, and the parts that the noise makes it easy to miss.
I will start with the pain, because anything else would be dishonest, and dishonesty is precisely what this project has always refused.
Part One: What Is Broken
Open a price chart for PIVX and look at it without flinching.
Look at the distance between where it was and where it is. Look at the years represented in that chart. Look at the people who are in those years, who believed in something, who held through multiple cycles, who watched projects with inferior technology and no philosophical coherence command prices and attention that PIVX has never approached. Look at it as a document of what sustained disappointment feels like when it is measured in numbers on a screen.
The price is low. It has been low for a long time. This is not a temporary condition awaiting correction. It is the current reality, and it has consequences that compound.
A low price means a low treasury. The PIVX treasury is funded by block rewards, which means its real-world value is directly tied to the price of PIVX. A depleted treasury means reduced capacity to fund development, to attract contributors, to communicate with the outside world, to compete for attention in a space where attention is the primary currency. The feedback loop runs in one direction and then doubles back on itself. Less funding means reduced visibility. Reduced visibility means lower adoption. Lower adoption means lower price. Lower price means less treasury.
This is not a mystery. It is a structural problem of considerable seriousness, and it deserves to be named as such rather than softened into a temporary setback.
The price has also done something to the community that is harder to measure but no less real.
People who believe in something and watch the market consistently disagree with their belief develop a particular kind of frustration. It is not the clean frustration of having been wrong. It is the more corrosive frustration of not knowing whether you are wrong. Of holding a conviction in one hand and a price chart in the other and being unable to reconcile them. Of watching years pass. Of explaining to people who ask why you are still here and hearing, in their polite responses, the unspoken question of whether you are simply unable to admit a mistake.
That frustration is legitimate. It deserves to be acknowledged without condescension and without the hollow reassurance that the market will eventually see what you see. Markets are not truth-finding mechanisms. They are attention-measuring mechanisms. They measure what is popular, not what is correct. Knowing this does not make the frustration smaller. It sometimes makes it larger.
Under this kind of sustained pressure, communities fracture. They fracture along existing fault lines that were invisible when things were going well. Old disagreements resurface. Blame circulates. The question of what went wrong becomes less a genuine inquiry and more a weapon deployed in arguments that are really about something else: the grief of watching something you believed in fail to be recognised by the world you believed it deserved.
The infighting is real. The toxicity is real. Some of it is a consequence of the price. Some of it may be a cause of the price. Some of it is simply what happens when passionate people disagree under conditions of sustained stress. All three of these things can be true simultaneously, and pretending otherwise helps nobody.
The whale dynamics deserve their own honest paragraph. In any small-cap project, large holders carry disproportionate weight. Their decisions affect price. Their presence in governance affects direction. Their behaviour in community spaces affects culture. When that influence is exercised with care and long-term vision, it can stabilise a project through difficult periods. When it is exercised carelessly, self-interestedly, or with the short-term logic that the attention economy rewards, it damages everything it touches. PIVX has experienced both. Whether this is a symptom of decline or a contribution to it is a question that cannot be answered cleanly, which is itself part of the problem.
And then there is the visibility.
Ten years of serious, documented technical work. A privacy implementation that is not marketing language but cryptographic fact. A governance model that is not a whitepaper promise but an operational reality. A fair launch that is not a talking point but a historical record. And most of the crypto world, including most of the people who care about financial privacy, has only the vaguest sense that PIVX exists.
This is a failure. Not of the technology. Not of the principles. A failure of communication, of positioning, of the ability to translate what is genuinely important into language that reaches people who have not yet decided to pay attention. In a world where attention is everything, the inability to capture it is not a minor inconvenience. It is an existential condition.
This is where the middle child lives. The one who does not perform. Who does not act out for attention, who does not manufacture crises to be noticed, who simply does the work with the quiet conviction that the work is real. In a world that rewards performance, the middle child is overlooked. Not because they are less. Because they have refused to play the game that determines who gets seen.
PIVX has refused to play that game from the beginning. The fair launch was a refusal. The absence of venture capital was a refusal. The decision to build the technology correctly rather than to build the narrative compellingly was a refusal. And in a market that is, at its core, a narrative competition, these refusals have had a price.
The question that the first section ends on, without resolving, is this: do those refusals represent a failure of strategy, or an expression of integrity? And is there a difference, in the long run, between the two?
Part Two: What Is Real
Most people arrive at a crypto project through the price and stay, if they stay at all, for the community.
I arrived through the community and stayed for everything else. This inversion is not incidental. It is the first thing I understood about what makes PIVX different, and understanding it properly requires sitting with it for a moment.
In 2019, the community I found was not performing helpfulness. It was not executing a retention strategy. The friendliness was not a marketing decision. The empathy was not a differentiating feature designed to attract a particular demographic. These qualities were simply present, in the way that certain qualities are present in a space where the people who built it built it according to those qualities from the beginning.
This is not sentimentality. It is a structural observation. Communities reflect their architecture. A project that launches with an ICO attracts, from its first moment, a population of early investors whose primary relationship to the project is financial. A project backed by venture capital carries, from its first moment, the preferences and timelines of its institutional stakeholders. A project with a pre-mine distributes influence asymmetrically from day one, in ways that shape governance and culture for years.
PIVX had none of these. The launch was fair. Every participant arrived on the same terms. The people who stayed were the people who chose to stay, for reasons that were not primarily financial, which meant the culture they built together reflected those reasons.
This is where the price critique, valid as it is, runs into its limit. A fair launch produces a different kind of community than a funded launch. The difference is real and measurable. It is also, in certain market conditions, a competitive disadvantage. Projects with institutional backing have marketing budgets, exchange relationships, and coordinated launch strategies. PIVX had people who believed in something and built accordingly, and obviously still has because they’re still building spearhead technology. That is not nothing. In certain conditions, it is everything. In the conditions of the last several years, it has not been enough to compete for attention. Both of these things are true, and holding them simultaneously is more honest than resolving them artificially in either direction.
Now look at what was built by those people over those ten years.
The privacy technology is not a claim. It is an implementation. PIVX uses zero-knowledge cryptography to shield transactions in a way that does not merely obscure data but ensures that no data is generated in the first place. This is a categorical distinction. Other privacy approaches, including those used by more prominent projects, only hide transaction information in more or less fancy ways. PIVX’s shielded transactions ensure there is nothing to hide, because there is nothing to find. The mathematics do not produce a trail. The regulator cannot demand records that were never created. The analyst cannot follow a path that was never laid.
This matters beyond the technical. It matters philosophically, and the philosophy connects to something that predates cryptocurrency by several thousand years.
Money, at its core, is a social instrument. It exists to allow strangers to exchange value without requiring prior relationship, shared identity, or mutual trust beyond the moment of exchange. For this to work, money must be neutral. It must arrive without a history attached to it. It must be fungible: any unit interchangeable with any other unit, carrying no moral weight from its previous holders, asking nothing of the parties except that the exchange is genuine.
Fungibility is not a feature of money. It is the condition that makes money possible. Without it, every transaction requires a judgment about provenance. Someone must decide which coins are clean and which are tainted. That someone is not neutral. They never are. And the power to make that judgment is the power to include or exclude participants in the economy itself.
Privacy is the mechanism of fungibility. Not an addition to it. The mechanism by which fungibility exists. Remove privacy and you remove fungibility. Remove fungibility and what you have is not money. It is a permission system wearing money’s clothes.
The Emperor Vespasian understood this in the first century AD, when he held up a coin and noted that it carried nothing of its history. Pecunia non olet. Money does not stink. PIVX was built on the same principle, expressed in modern cryptographic terms. The shielded transaction is the descendant of Vespasian’s coin: neutral, clean, carrying nothing forward that would compromise the equality of the parties in the exchange.
This is not a niche concern. It is the philosophical foundation of what money should be, and it is being systematically dismantled by the regulatory frameworks, the compliant stablecoins, and the programmable currencies that are arriving now dressed in the language of modernisation and consumer protection. In that context, a project that has spent ten years building genuine fungibility through genuine privacy is not marginal. It is necessary.
Look also at what ten years in this space actually means.
The crypto graveyard is extensive and well-populated. Projects with larger communities, bigger budgets, better marketing, more exchange listings, and more coherent narratives have failed. They failed because the foundations were not sound, because the incentives were not aligned, because the people who built them were building for an exit rather than for the work. A project optimised for the attention economy performs well until it doesn’t and then collapses entirely, because there was nothing underneath the performance.
PIVX is still here. Through multiple bear markets that destroyed projects with more resources. Through exchange delistings that would have ended projects with shallower communities. Through regulatory pressure on privacy coins specifically, pressure that has forced less resilient projects to compromise their core functionality or exit the market entirely. Through years of being overlooked by the capital and attention that flow toward whatever the current narrative favours.
Still developing. Still governed by its community. Still building the technology that the mathematics supports.
Resilience of this kind is not luck. It is a consequence of foundations. A project built on hype collapses when the hype collapses. A project built on genuine technology and genuine community retains those things through conditions that consume everything else.
And the governance. Real votes by real participants on a real treasury, with real outcomes that determine real direction. Masternode operators who are not passive investors but active stewards. Developers who propose and argue and revise in public because the quality of the argument is the only thing that determines whether a proposal advances. A system without a CEO to blame or a board to defer to or an institutional investor whose preferences silently shape every decision. Just people, with genuine power, exercising it imperfectly in the way that genuine power is always exercised.
This is what democracy looks like when it works. Messy. Slow. Occasionally frustrating. Capable of producing decisions that turn out to be wrong. Incapable of being purchased.
Part Three: What Remains
Here is the honest position, stated plainly.
The price is low and the consequences are real and the community has been damaged by years of pressure and the visibility problem has not been solved. These things are true.
The technology is sound and the foundations are genuine and the fair launch was a moral choice with structural consequences and the resilience is documented and the governance is real and the thing being built is more important now than it was when it was built. These things are also true.
Both sets of truths exist simultaneously. The article that pretends otherwise, in either direction, is not honest. The promotional piece that skips the first set insults the intelligence of everyone who has watched the price chart. The dismissal that ignores the second set mistakes a market verdict for a factual one.
Markets are not oracles. They are measuring devices for a specific and limited thing: what is currently capturing attention and capital. They measure this with great efficiency. They measure almost nothing else. A low price tells you that PIVX is not currently winning the attention competition. It tells you nothing about whether the thing being built is correct, whether the foundations are sound, whether the problem being solved is real, or whether the solution is working.
The attention economy has produced a world in which everything is measured in performance. Likes. Clicks. Price. Market cap. Projects are designed for narrative first and substance second, because narrative is what captures attention and attention is what capital follows. The result is a landscape full of things that look impressive and require constant maintenance and begin to fail the moment the attention moves elsewhere.
PIVX was built in the opposite order. Substance first. Narrative almost not at all. The fair launch was a decision against performance. The decade without venture capital was a decision against the kind of growth that requires surrendering direction to people whose interests are not yours. The choice to implement zero-knowledge privacy correctly rather than quickly enough to announce was a decision for the work over the appearance of the work.
These decisions produced a project that performs poorly in the attention economy and soundly in every other dimension that matters for what money should be. That is not a comfortable position. It is an honest one.
We live in a world that is simultaneously building the infrastructure of total financial surveillance and creating a growing population of people who will one day need an alternative. The programmable stablecoin. The MiCA-compliant currency that can be frozen on instruction. The CBDC that arrives as an app and departs with your financial autonomy. These are not distant futures. They are present conditions, advancing.
In that world, the thing PIVX represents is not a niche interest. It is the preservation of what money has always needed to be in order to function as money: neutral, fungible, private, belonging to the person who holds it rather than to the institution that issued it. The market has not priced this yet. It will, when it must. Markets always price necessity eventually. The question is whether the projects that understood necessity early will still be standing when the pricing happens. PIVX has survived everything that the last ten years could produce. There is reasonable basis for believing it will still be standing.
I came to PIVX in 2019 because of how people treated each other. I stayed because of what I understood afterward. I am still here because of both, and because looking honestly at everything that is broken has not changed what I see when I look at what is real.
The price chart is real. The community fractures are real. The treasury constraints are real. The visibility failure is real.
The technology is real. The foundations are real. The fair launch is real. The ten years are real. The governance is real. The mathematics of privacy that produce genuine fungibility are real. The importance of what is being preserved, in a world that is actively dismantling it, is real.
All of these things are true at the same time. Living with that complexity, without resolving it falsely in either direction, is what intellectual honesty requires. It is also, I think, what the project has always required of the people who build it and govern it and hold it through the years when the market is not paying attention.
The sun does not stop shining because clouds are in the way. The light is still there. The warmth is still there. The thing that makes growth possible is still there, unchanged by the weather that moves across it.
PIVX has been building in the clouds for a long time.
The sun is still shining. It does not need us to see it to continue.
PIVX. Your Rights. Your Privacy. Your Choice.

getstandardfee RPC and Four Security Fixes
We are releasing Zebra 6.1.0 today. This release adds a new getstandardfee RPC and fixes four security issues affecting block verification, node liveness, and mining. There are no consensus changes. All node operators are encouraged to upgrade.
getstandardfee RPC
A new getstandardfee RPC returns the ZIP-317 marginal fee, giving wallets and other clients a direct way to query the current standard fee. The value is also exposed to Rust consumers as transaction::zip317::MARGINAL_FEE. (#10717)
getblocktemplate Can Produce Oversized, Invalid Blocks (Low)
When Zebra built a block template, its ZIP-317 transaction selector budgeted mempool transactions against the full maximum block size while reserving space only for the coinbase transaction, not for the serialized block header or the transaction-count field, both of which count toward the limit (roughly 1,490 bytes on Mainnet and Testnet). If the selected transactions filled that margin, the assembled block exceeded the consensus size limit, so a miner would perform proof-of-work on a block that every node rejects, wasting the work; an attacker able to place valid, selectable transactions in a victim miner’s mempool could deliberately shape templates into the affected range. Non-mining nodes were unaffected, and because oversized blocks are correctly rejected there was no consensus divergence. Zebra now reserves the network-specific header size and the maximum transaction-count width before selecting transactions, so templates stay within the limit. Thanks to @ebfull of Project Tachyon for reporting this issue via coordinated disclosure.
GHSA-g7c4-2w6c-cr3r: Unattributed Pushed-Transaction Failures Allow Batch-Verification Poisoning (Moderate)When a directly pushed mempool transaction failed verification, Zebra did not record the sending peer’s address on the failure, so the peer was never misbehavior-scored or banned. Because Orchard proof verification runs through a process-global batch verifier shared by mempool and block verification, a peer could repeatedly push transactions carrying invalid Orchard proofs at no cost, forcing each shared batch onto the slow per-proof path, including honest proofs from block processing batched alongside, and sustaining a measured block-processing slowdown for as long as the traffic continued. There was no crash, consensus divergence, or state corruption. Zebra now attributes pushed-transaction verification failures to the sending peer so the existing misbehavior scoring can ban it. This closes the verification-failure attribution gap left by the admission-accounting fix in GHSA-m9xx-8rcj-vmgp. Thanks to @ebfull of Project Tachyon and @ValarDragon of Valar Group for reporting this issue via coordinated disclosure.
GHSA-4g24-549m-hp75: Quadratic Transparent Value Check in Block Verification (Moderate)During contextual verification, Zebra checked the remaining transparent value of every non-coinbase transaction by cloning and converting the entire block-level spent-output map once per transaction, turning a linear check into quadratic work. A block near the size limit packed with minimal single-input transactions (up to roughly 26,000) could take over 52 seconds to validate on fast hardware. Because the affected code runs only after proof-of-work checks pass, triggering it requires a validly mined block (produced directly or by seeding the mempool for an honest miner), which bounds the attack to a one-time, self-clearing stall per block with no crash, consensus divergence, or state corruption. Zebra now passes each transaction only the outputs it spends, making the check linear in total inputs. Thanks to @ebfull of Project Tachyon and @ValarDragon of Valar Group for reporting this issue.
GHSA-8gxx-hc65-vv82: Chain Stall via Staleparent_error_map Entry (Moderate)
When a block failed contextual verification, Zebra recorded its hash in an in-memory map and propagated that failure to any child block whose parent was in the map, but entries were only removed by a fixed size limit or a restart, never when the canonical block at that hash later committed successfully. Using the same ZIP-244 coinbase-malleability primitive as GHSA-4m69-67m6-prqp, an unauthenticated peer that won the propagation race could get a poisoned block sharing a canonical block’s hash rejected first, so the canonical successor was then rejected against the stale entry, stalling the node at that height for roughly 41 hours per trigger and repeatable on each new block. The stall cleared on restart, with no crash, consensus divergence, or state corruption. Zebra now removes a hash from the map when the canonical block at that hash commits successfully. Thanks to @deedim for reporting this issue, including a deterministic proof of concept and analysis of its relationship to GHSA-4m69-67m6-prqp.

PIVX Weekly Ecosystem Update (11th July – 17th July 2026) was originally published in PIVX on Medium, where people are continuing the conversation by highlighting and responding to this story.
Recorded live at the New Media Summit, Erik Torenberg sits down with Replit founder and CEO Amjad Masad to discuss founder-led storytelling, building in public, and the role of media in company building.
Masad reflects on Replit’s decade-long journey, including the years before the company’s recent breakout growth, and explains why communicating a vision can be just as important as executing on it. He argues that for many founders, especially those building ambitious products ahead of the market, telling a compelling story is often necessary to attract talent, capital, and early believers.
The conversation explores social media, authenticity, public communication, company-building, and how founders can develop a voice that resonates beyond their product. Along the way, Masad shares lessons from building Replit, navigating controversy, and why he believes founders should think carefully about when to go direct and what story they're trying to tell.

Yesterday, Valar Group and Project Tachyon announced Zakura, a new Zcash full node built from the Zebra codebase. We want to state plainly: this is good for Zcash, and we welcome it.
Zebra was built to be forked. We released it under permissive open-source licenses precisely so that anyone could build on it and improve it. Zakura’s engineering is impressive including faster initial sync, pruning, snapshot bootstrapping, and a compatibility path for zcashd operators — and it arrives at the moment the network needs more capable options, not fewer. We congratulate the Zakura team, several of whom have also contributed directly to Zebra itself, including to our most recent release. This is an example of open source working as intended.
First things first: NU6.3 activates this month. Zebra 6.0.0, released July 10th, fully supports the Ironwood network upgrade, which activates on Mainnet at block height 3,428,143 — around the end of July. With zcashd reaching end of life, every node operator must be running NU6.3-capable software before activation. If you run Zebra today, upgrade to 6.0.0 now. If you’re migrating from zcashd, both Zebra and Zakura have ready paths, and our documentation and support channels are open to help either way. The single most important thing for the network this month is that every operator completes this upgrade on time.
One request, whichever node you choose. The events of this past June were a reminder that a consensus network’s security depends on independent verification — different implementations, independently built and reviewed, each checking the other’s work. If your infrastructure moves to Zakura, we’d encourage you to keep a Zebra node running alongside it as an independent consensus check. It’s inexpensive, it’s standard practice for critical infrastructure, and it strengthens the network for everyone.
Zebra’s mission going forward. Zcash Foundation (ZF) will maintain Zebra for the long term as the network’s independently governed reference implementation — consensus-current, and rigorously reviewed. Alongside it, we are investing in verification infrastructure that serves every implementation: cross-implementation conformance test suites and differential testing that catches consensus divergences before they reach mainnet. A network as valuable as Zcash deserves an assurance layer that doesn’t depend on any single team getting everything right, including us.
We also want to state a governance principle clearly: the Zcash protocol belongs to its community, and it evolves through the open ZIP process — not through any one implementation, organization, or entity, and that includes ZF. We will support formal recognition of any implementation that demonstrates conformance to the protocol specification, and we’ll build the public conformance infrastructure that makes “demonstrates conformance” a testable, neutral standard rather than a matter of opinion.
ZF has the independence and the resources to do this patient work for the next decade. More implementations, more builders, and more velocity are good for Zcash — our job is to make sure the network they all share stays secure, verifiable, and governed in the open.
The post Zebra, Zakura, and the road through NU6.3 appeared first on Zcash Foundation.
Nish Khandwala and David Eng are building the AI agent platform to serve every function across the health system: clinical, operational, and administrative.
By Alfred Lin Published July 16, 2026 David and Nish.Healthcare hasn’t historically been known as a fast or early technology adopter. Researchers struggle to access external data, collaborate with research institutions, and navigate complex regulations. Hospitals and health systems try to create their own tools or implement narrow point solutions from vendors, but they too often stall in experimentation and never reach patient care.
Health systems need the right platform to quickly adopt AI, so they can refocus their time back on improving patient outcomes and providing better care.
Bunkerhill Health is that platform. Their core product, Carebricks, lets health systems create and deploy AI agents across any clinical or operational use case – turning the data a hospital already generates into timely action for the patients who need it. We first backed Nish Khandwala and David Eng at the seed, and we are proud to continue to double down.
Nish did not read about this problem; he lived it. As a graduate student at Stanford, he helped build an algorithm that could estimate a patient’s coronary artery calcium score from a routine chest scan – a signal of cardiovascular risk that normally requires a dedicated, more invasive test. The algorithm was good enough to be published in Nature Digital Medicine. And then it went nowhere. Around the same time, Nish’s father suffered a heart attack, and his CT scan carried the very calcium signals the Stanford algorithm was built to catch. It is one thing to know that proven science sits unused in academic papers. It is another to watch it fail to reach your own family.
That experience taught Nish something non-obvious: the bottleneck in healthcare AI is not the technology, it is everything around it. So Bunkerhill initially built a system that gets an idea from research to the bedside – sourcing data from a consortium of leading academic medical centers, validating the model, shepherding it through FDA clearance, and installing it into the hospital where a clinician and a patient can actually use it. But they ran into another problem: health systems do not have the time or resources to deploy one-off AI solutions. So Bunkerhill built Carebricks to allow any health system to bring their ideas to life with AI agents across clinical, operational, and administrative work in one central platform. Health systems bring the ideas and the clinical judgment, and Bunkerhill turns them into agents.
We have watched this compound in the field. At UTMB Health, Bunkerhill rapidly went from one agent in production to more than twenty, spreading from one specialty to the next as clinicians saw what it could do. And just as importantly, it has allowed UTMB to consolidate what used to be multiple vendors’ point solutions into a single platform with Carebricks.
Bunkerhill’s agents run quietly in the background, surfacing the findings that matter and catching the cases the system would have missed. Not to automate clinicians away, but to automate manually-intensive work so clinicians and their teams can focus more time on what they do best: caring for their patients.
Nish and David are outlier founders with the technical depth and the relentlessness this problem demands, and they are pulling healthcare toward faster iteration and better outcomes for every patient, not just the average one. We are excited to partner with Nish, David, and the entire Bunkerhill team as they build the agentic AI platform for healthcare.

Nim, Leon, Linda and Itamar are building an AI employee powered by real-time computer use and vision.
By Shaun Maguire Published July 16, 2026 Leon, Nim, Linda and Itamar.The frontier of AI is moving at a pace most of the economy can’t match. Labs ship new capabilities every month, while the Fortune 500 scrambles to absorb what came out last year. Watching this gap widen, it’s clear that the bottleneck isn’t only intelligence, it’s helping customers understand what AI can actually do for them. It’s the reason we’re thrilled to partner with Sable.
Imagine your business wanted every buyer to fully understand your product or service, without the realities of time and scale. What would you do? You’d put your best product expert in every conversation. They’d learn each customer’s goals and deeply empathize. They’d demonstrate the product instead of describing it. They’d answer every question, adapt to every level of experience, and stay until the customer understood not just what your product is, but what it could do for them. And they wouldn’t do this for your largest accounts alone. They’d do it for every prospect.
Sable makes this possible. It created “Aidan,” the first AI employee, who leads its own customer calls with vision, voice, video and real-time browser interaction. Sable is less than one year old, but frontier companies are already using it to explain their products, including Notion’s custom agents and Decagon’s agent-building platform, alongside large public enterprises. There is a staggering range of applications and organizations eager to deploy AI employees, from the world’s fastest-growing companies looking to keep pace with demand, to large enterprises seeking to accelerate growth with AI. We’ve been blown away by the market pull for this new capability, with +150 companies already on Sable’s waitlist.
Enterprise deployments of multimodal AI employees require a combination of customer obsession and technological breakthroughs at the frontier of the field: low-latency browser use, real-time vision and simultaneous human-agent interaction. Problems like these are ultimately won by people. Sable is exceptionally well-positioned to solve them.
The four founding team members are friends from Harvard, where they studied post-training, reinforcement learning and multimodality. They worked at SpaceX, Google, Meta and Together AI. Nim, co-founder and CEO, is a rare combination of a leader and visionary. He has an innate talent, and impressive experience recruiting the highest-caliber people to work together and achieve the unlikely. That philosophy has shaped Sable from the beginning: the company is obsessed with hiring exceptional talent. Among their first hires is a unique mix of applied AI researchers and customer-obsessed engineers, including ten Harvard alums, former quantitative traders and International Math Olympiad winners.
The combination of an all-star team, undeniable market demand and bold vision is why we were thrilled to lead Sable’s seed round and co-lead its Series A. We believe Nim, Leon, Linda and Itamar are building foundational infrastructure for companies to manage their AI employees, and we couldn’t be more excited to be on this journey with them.

Every blockchain today relies on replication techniques first developed in the 1980s by researchers who weren't thinking about cryptocurrencies at all.
In this episode, Tim Roughgarden speaks with MIT professor and Turing Award winner Barbara Liskov, one of the pioneers of programming languages, fault tolerance, and distributed systems. Joined by a16z crypto research partner Ittai Abraham, they trace the evolution of ideas that now underpin modern blockchain networks.
The conversation explores viewstamped replication, Practical Byzantine Fault Tolerance (PBFT), state machine replication, and why concepts developed decades before Bitcoin became the foundation for today's blockchain protocols. Along the way, Liskov reflects on the relationship between theory and practice, the importance of modularity and formal reasoning, and why AI is creating a new generation of systems research.

We are releasing Zebra 6.0.0 today. This is the first stable release with support for the NU6.3 “Ironwood” network upgrade on Mainnet, setting the Ironwood activation height at 3,428,143. It promotes the work first shipped in 6.0.0-rc.0 to a stable release, and adds a mempool-verification security fix, several networking and read-state fixes, and a new build-time dependency (libclang) made since the release candidate. All node operators should upgrade before NU6.3 activates on Mainnet.
Zebra 6.0.0 activates the NU6.3 “Ironwood” shielded pool and v6 transaction format on Mainnet at height 3,428,143 (expected around 13:00 UTC on July 28, 2026), alongside the Testnet activation height of 4,134,000 introduced in the release candidate. (#10938) Ironwood adds a new shielded pool that reuses Orchard’s Action and Halo2 proof system while adding its own note commitment tree, nullifier set, chain value pool, and chain-history metadata, delivered through a new v6 transaction format.
The z_gettreestate, z_getsubtreesbyindex, and verbose getblock RPCs expose the Ironwood note commitment tree and its subtree roots from NU6.3 activation, and the getblockchaininfo and getblock valuePools fields include the Ironwood pool. (#10762, #10888)
This stable release also updates the zcash_* and orchard crates from the pre-release versions used in the release candidate to their released NU6.3 versions.
For the full set of features first introduced in the release candidate (signed pre-built zebrad binaries, the block-notify command, resumable indexer streaming, and the two security fixes GHSA-x6v8-c2xp-928m and GHSA-m9xx-8rcj-vmgp), see the 6.0.0-rc.0 release notes.
Zebra ran full script verification on a mempool transaction before the cheap policy checks that would reject a non-standard, high-signature-operation P2SH script, so a peer sending transactions that are cheap to produce but expensive to verify could occupy the bounded verification capacity and degrade the responsiveness of mempool and block verification while the load persisted. The impact is availability degradation only, with no crash, consensus fault, invalid-block acceptance, or loss of funds, and it clears once the load subsides. Zebra now rejects mempool transactions with non-standard transparent inputs before script verification, and script verification now runs on the shared Rayon thread pool rather than blocking an async runtime worker; block (consensus) validation still runs full script verification.
Thanks to ouicate for reporting this issue, supplying a proof of concept, and refining the analysis during triage.
This is the latest in a series of mempool peer-fairness and resource-accounting hardening fixes, following the per-peer download cap (GHSA-4fc2-h7jh-287c) and the direct-push accounting fix shipped in 6.0.0-rc.0 (GHSA-m9xx-8rcj-vmgp).
Bug Fixes Since the Release Candidate Mempool Stays Active Through Sync NoiseOnce the mempool has started, Zebra no longer clears it or cancels its queued transaction verification when a transient signal (which lower-work forks or stale peers can trigger) reports the node is far from the tip. Initial mempool activation still waits until Zebra is near the chain tip. (#10929)
Peer Connections at the Chain TipZebra no longer disconnects from peers that return empty FindBlocks or FindHeaders responses when the local node is at or near the chain tip. (#10732)
Fixed a read-state syncer startup hang where a co-located consumer whose finalized state had caught up past the node’s non-finalized root would re-subscribe endlessly instead of syncing, advancing only one block per newly mined block. (#10841)
Syncer RestartsFixed syncer restarts caused by incorrect error downcasting; wrapped state-commit duplicate errors are now correctly classified as duplicate requests. (#10916)
Build and Compatibility Changes New build dependency:rocksdb was updated to 0.24, and the bundled librocksdb-sys now always runs bindgen, so libclang is required at build time (in addition to protoc and a C++ compiler), even when linking a system RocksDB via ROCKSDB_LIB_DIR. Install libclang-dev (Debian/Ubuntu), clang (Arch), or the equivalent for your platform. (#10922) The workspace (libraries) minimum supported Rust version is raised from 1.85.1 to 1.88. The zebrad binary MSRV is unchanged at 1.91. (#10927)
State Database Format
Zebra 6.0.0 uses state database format 28.0.0, introduced in the release candidate for the Ironwood shielded pool. This is a major-version bump that migrates in place from the previous major format, so no resync is required. Note that downgrading is not supported, so if you want to ensure you can rollback to an older version of Zebra if something goes wrong, then backup the state before upgrading Zebra.
UpgradingYou can find the release on GitHub, crates.io, and Docker Hub. Because this release sets the NU6.3 Mainnet activation height, all node operators should upgrade before Ironwood activates to remain on the correct chain.
Thank You to Our ContributorsThis release was made possible by the work of @conradoplg, @Cosmos-Harry, @dannywillems, @jvff, and @upbqdn. Thank you for your continued contributions to Zebra.

PIVX Weekly Ecosystem Update (4th July – 10th July 2026) was originally published in PIVX on Medium, where people are continuing the conversation by highlighting and responding to this story.
We're excited to share a special feed drop from The a16z Crypto Show.
In the first episode of First Principles: The Scientific Roots of Blockchain Technology, Tim Roughgarden and Ittai Abraham trace the decades of computer science research that laid the foundation for modern blockchains.
Long before Bitcoin, researchers were studying one of distributed computing's hardest challenges: how independent machines can reliably agree on a shared state, even when some participants are faulty or malicious. Bitcoin didn't invent that problem, but it introduced a breakthrough solution in a radically different, permissionless setting.
The conversation explores Byzantine agreement, state machine replication, proof of work, proof of stake, Tendermint, Casper, DAG-based protocols, and why concepts developed decades ago continue to shape the design of today's fastest and most secure blockchain networks.

As part of our summer replay series, we're revisiting one of our favorite conversations from the past year.
Mark Zuckerberg and Dr. Priscilla Chan join Ben Horowitz, Vineeta Agarwala, and Erik Torenberg to discuss the Chan Zuckerberg Initiative's ambitious effort to help cure, prevent, and manage disease by the end of the century.
Rather than funding individual breakthroughs, CZI is focused on building the tools and infrastructure that can accelerate scientific discovery across entire fields. The conversation explores Biohub, Cell Atlas, virtual cell models, open biological datasets, and the growing role of AI in helping researchers better understand human biology.
They discuss why biology still lacks a "periodic table of elements," how AI could help scientists test hypotheses before running expensive experiments, and why pairing frontier biology with frontier AI may unlock a new era of medical discovery.

The Web continues to evolve, bringing new and emerging challenges and threats to users. Brave was born to meet exactly this kind of challenge: to fix the Web by building user-first alternatives to more privacy-harming defaults. Since then, Brave has expanded that user-first mission into a product used by over 120 million people worldwide.
With the September 2016 introduction of the Brave Payments proof of concept, Brave began applying that mission to Web monetization, with features that combine zero knowledge and blockchain cryptography. Lessons learned from the Brave Payments proof of concept drove the evolution to the Basic Attention Token (BAT) and Brave Rewards, growing an ecosystem of private advertising and creator contributions to tens of millions of Brave Rewards users and over 2 million verified websites and content creators.
The economics of the Web are undergoing rapid change and innovation. AI adoption is changing the way users engage with content. Stablecoins and blockchain technology are upgrading the payments and transactional space, while merchants, restaurants, and the places we make everyday purchases adopt “cashless-only” payments. Without a digital alternative, the anonymity afforded by the wallet and cash in your back pocket may be lost in a cashless economy.
Creators continue to face challenges for how to fund their content, and those challenges have grown significantly with AI. With the growth of AI use and summarization, creators often have less visibility into where and how their content is being used, receive less attribution for that use, and generally are not compensated for it.
Users and creators should earn in this ecosystem, and not be left behind. Brave aims to rise to meet these new challenges, while growing BAT utility and the larger ecosystem. This means continuing the tradition of building solutions that meet users and creators where they are, and including them in the economics. This also means meeting users where they are transacting both within and beyond the browser. BAT Roadmap 4.0 therefore marks an important shift in the evolution of the Basic Attention Token, Brave Rewards, and Brave Creators within the transactional attention economy.
InitiativesRoadmap 4.0 brings together the following mutually reinforcing initiatives:
Internet-payments x402 and Machine Payments Protocol (MPP): Supporting autonomous agentic payments in the browser, for Brave’s premium offerings and for Creator content. A new, unified Brave Wallet: A new, in-browser Brave Wallet experience that brings traditional payment methods (including saved credit cards, self-custody crypto accounts, and Brave Rewards) into one intuitive interface. BravePay: A stablecoin protocol layer that enables users, creators, and merchants to transact, earn, and settle privately on-chain. Brave Rewards Card: A stablecoin-powered virtual and physical payment card with competitive purchase rewards. Creator Contribution Protocol: A system for compensating verified creators when their content is used in AI experiences. BravePay SDK and Rewards SDK: Open-source SDKs that allow developers to quickly integrate BravePay and Brave Rewards functionality. For merchants, the SDKs will make it easy to support payment methods built on the BravePay protocol. For app developers, the SDKs will enable user onboarding to BravePay-powered payments and provide access to the broader Brave Rewards ecosystem, including Brave Ads for additional monetization, and Brave Creators, connecting developers to millions of registered websites and content creators.As we iterate and continue to pursue product-market fit, some of the roadmap items above may become less of a focus over time, while others may be prioritized. Useful roadmaps provide direction while remaining flexible enough to adapt to unforeseen challenges. We plan to publish regular updates on roadmap progress, along with publishing detailed posts and calls to action for the community for items in the sections below.
Internet-payments x402 and Machine Payments Protocol (MPP) support in BraveA key foundational step in supporting stablecoin payments for agentic commerce and autonomous systems, Brave will introduce support in the browser for x402 and Machine Payments Protocol (MPP) transactions. Brave’s implementation will use the HTTP 402 Payment Required status as a shared mechanism, providing equal first-class support for x402 and MPP options. For example, in the case of a Creator or API with protected content the browser will receive a 402 response code with a compatible x402 or MPP body, and provide payment for access to protected content. In addition to browser support, Brave will also be adding support for x402 and MPP transactions to the Brave Search API and other Brave offerings over time.
For a closer look, the open-source bx402 project with an example for the Brave Search API is available to view and reference from our brave-experiments GitHub repository.
A new, unified Brave WalletThe browser-native, self-custodial Brave Wallet will undergo a complete redesign and evolve into the new unified Brave Wallet.
The new Brave Wallet will include:
Traditional saved payment methods including debit cards, credit cards, and the Brave Rewards Card, all stored locally in the browser. Self-custody multi-chain crypto accounts with on- and off-ramp funding, the features users already know from the crypto Brave Wallet, and support for the upcoming BravePay protocol integration. Brave Rewards integrated directly into the wallet, allowing users to opt in and earn rewards through use of the Brave Rewards Card, and benefit from transactions with participating partner brands and other Brave Wallet-related activities.The team is looking forward to inviting participation in testing and feedback for the new Brave Wallet experience from the community and our userbase. We are aiming to post invitations with calls to action for users and the community to test and provide feedback for prototypes this fall.
The Brave Rewards CardOne of the most exciting initiatives in BAT Roadmap 4.0 is the Brave Rewards Card: a Brave-branded virtual and physical payment card designed for everyday purchases in eligible countries.
Powered by the BravePay protocol and GENIUS-compliant stablecoins, the Brave Rewards Card meets users and merchants where they are by leveraging traditional payment rails.
The Brave Rewards Card extends Brave Rewards beyond the browser. As users make purchases with the card, they will earn BAT rewards, while also unlocking exclusive Brave Rewards offers and benefits. The card will be available as both a virtual card in Brave Wallet (and other major digital wallets), as well as in physical form for in-store purchases.
To bring the Brave Rewards Card to users, Brave will partner with a compliant card issuer and support as many countries as possible at launch. Additional details regarding the card partner, geographic availability, purchase rewards, and the Brave Rewards Card waitlist will be shared in a future announcement.
BravePayOver the last several years, stablecoins have emerged as a powerful new payment rail, with tens of trillions of dollars in transaction volume. We aim to bring stablecoin-based peer-to-peer and e-commerce transactions into a protocol that’s easy to onboard and use, enabling more than 120 million Brave users to benefit from them.
To achieve this, Brave plans to introduce BravePay: a stablecoin protocol layer designed around self-custody, privacy, and ease of use.
What BravePay enables Self-custody by default: Users maintain control of their funds. Simple onboarding: New users can on-ramp from fiat directly into BravePay. Easy transactions: Payments can be sent and received using .brave addresses. Private transactions: Bringing privacy to your wallet so what you buy isn’t tracked by Big Tech or payment networks. Support for stablecoins: Experienced crypto users can transact using GENIUS-compliant stablecoins they already have in their wallets. Compatibility with x402 and MPP payment integration Rollout strategyNear term
Integration with Brave Wallet Integration with the Brave Rewards CardLonger term
Merchant support for seamless e-commerce transactions. Introduction of an open-source SDK allowing developers to integrate BravePay into their applications.BravePay will extend Brave’s user-first approach to privacy, transactions, and rewards beyond the browser, meeting users where they transact in the real world.
Paving the way for the agentic economyWhile our immediate focus remains on Brave users, we are closely watching the rapid development of machine-to-machine and human-to-machine payments in the emerging agentic economy. A growing number of protocols, including x402 and MPP, are competing for adoption.
BravePay lays the groundwork for payments between humans and machines alike. As this ecosystem evolves, Brave aims to enable browser-driven interactions with agents that unlock entirely new and exciting use cases with these agentic payment capabilities but with additional privacy-preserving options. This will start with BravePay compatibility with the Brave x402 and MPP implementation, and extend to other options over time.
BAT buybacks and Brave RewardsIn addition to the BAT purchases Brave already makes for user rewards through Brave Ads campaigns, the BAT Roadmap 4.0 introduces new transactional BAT utility and rewards for Brave Rewards users and verified Brave creators.
A percentage of Brave’s net revenue from Roadmap 4.0-related sources will fund BAT buybacks that support user rewards, creator contributions, and program growth through the BAT User Growth Pool (UGP) Reserve. For example, these revenue sources are expected to include:
Brave Wallet revenue-generating features Swaps Cross-chain bridging NEAR Intents On- and off-ramps .brave domains sold through Brave Wallet Brave Rewards Card revenue, including revenue associated with the Brave Rewards Card as it becomes available in eligible markets. BravePay protocol revenue, a percentage of which will be used for BAT buybacks.Additional details regarding relevant tokenomics in Brave Rewards will be shared in a separate blog post later in 2026, and will be included in relevant posts for other roadmap items as development progresses.
Opportunistic BAT buybacksBrave also plans to make opportunistic BAT buybacks in addition to revenue-generated buybacks. These buybacks will support program growth, incentives, and expansion of the BAT UGP Reserve.
Buyback timing and amounts will vary based on market conditions and program needs. Brave will publicly disclose opportunistic buybacks through the Brave Transparency and BAT Ecosystem Growth pages.
Updates to Brave RewardsAs Roadmap 4.0 expands BAT utility across Brave Wallet, BravePay, and the Brave Rewards Card, Brave Rewards will also evolve beyond its original browser-based rewards model. Users will continue to earn for their attention to eligible privacy-preserving Brave Ads units, while new rewards experiences will increasingly focus on offers, purchases, wallet activity, and loyalty.
Brave AdsThe Brave Ads Notification unit will begin a gradual sunset by the end of 2026 as Roadmap 4.0 utility features are activated. Over time, notifications will increasingly be used to inform Brave Rewards users about offers from participating brands and categories available through the Brave Rewards Offer Wall, rather than serving as ad units themselves.
Brave Rewards Offer WallWe will also introduce additional personalization features, including the ability for users to subscribe to favorite brands and categories for a more tailored Offer Wall experience.
Loyalty program Loyalty tiers that provide additional rewards based on Brave Wallet and Brave Rewards Card usage, duration of participation, and the amount of BAT held over time. BravePass, a crypto-abstracted Brave Rewards experience in which BAT earned through Brave Rewards is locked into a BravePass, giving the pass holder access to Brave Premium offerings and potentially other Brave benefits.Together, these updates extend Brave Rewards from attention-based rewards into a broader rewards and loyalty system encompassing purchases, wallet activity, and more. As with Brave Premium and the existing Brave Rewards ecosystem, all of these new features can be implemented using privacy-preserving cryptographic protocols, allowing users to earn rewards without sacrificing their privacy.
Creator Contribution ProtocolToday, AI models and tools use creator content during both training and inference without compensating the creators whose work makes those systems valuable. We believe that when AI systems generate value from creator content, a portion of that value should flow back to those creators in a verifiable way.
To make this possible, content creators, publishers, and AI products need to be connected through a shared, verifiable protocol. This is the Creator Contribution Protocol. With the protocol, we envision registered creators receiving micro-royalty payments for qualified content use when participating AI products access their content.
BAT has already proven itself as the leading unit of account for attention on the Web, allowing millions of users to contribute to their favorite content creators. With millions of creators—including some of the world’s largest publishers—already registered with Brave Creators, Brave and BAT are in a unique position to lead by example on how content creators can earn with AI.
Later in 2026, we plan to publish a blog post specifically covering the Creator Contribution Protocol, and look forward to engaging with the community and Brave Creators to receive input and test as we go through the research and development process.
CommunityCommunity participation will be a key part of BAT Roadmap 4.0. Over the past year, we’ve established a testing program and evolved the BAT Ambassadors program to support the road ahead. For example, BAT Ambassadors, alongside the broader BAT community, will help test, provide feedback on, and validate new features and experiences as they are introduced.
Building products that users adopt and enthusiastically recommend to their friends and family is central to the roadmap’s success. We’re excited to work closely with the community and our lead users to make this a reality. More details will be shared in future updates and calls to action.
ConclusionRoadmap 4.0 brings BAT into a broader set of everyday interactions for users, merchants, and creators:
The unified Brave Wallet combines traditional payment methods with next-generation transaction capabilities powered by BravePay. The Brave Rewards Card extends BAT utility to traditional payment rails, both inside and outside the browser. Revenue from Brave Wallet, the Brave Rewards Card, and BravePay will fund BAT buybacks that support purchase and transaction rewards for Brave Rewards users. The Creator Contribution Protocol modernizes the Brave Creators model, opening new verifiable ways for creators to earn as AI changes how content is created, curated, and consumed.Together, these initiatives create a system in which browsing, transacting, and content creation can each contribute to sustained BAT demand and broader BAT utility across the evolving user-first Web.
Users and supporters of Brave can help advance this mission by adopting Brave Wallet and BravePay. Those who configure their AI agents to transact through BravePay will also position themselves at the forefront of the emerging agentic economy, and be rewarded for their participation.

Adam Neumann joins Marc Andreessen, Ben Horowitz, and Erik Torenberg for a candid conversation about entrepreneurship, failure, and building Flow.
Neumann reflects on his childhood, military service, immigration to the United States, the rise and fall of WeWork, and what he learned from one of the most scrutinized founder journeys in technology. He explains why Flow is focused on rethinking housing, community, and belonging, and why he believes technology can fundamentally improve how people live.
The conversation explores resilience, company building, leadership, real estate, software, flexible living, and the global housing crisis. Along the way, Neumann discusses rebuilding trust, designing for community, and why some of the biggest entrepreneurial opportunities emerge from deeply personal experiences.

Today we’re releasing the improved Brave Place Search API. It’s a single endpoint for finding places in the physical world (such as businesses, landmarks, and points of interest) drawn from our index containing about 200 million points of interest worldwide, and growing.
This API is the backbone of place search in Brave Search, which handles over 2.2 billion queries a month and powers the Brave Search map. The improved version is available today for public access through the Brave Search API, on the Search plan, at a flat $5 per 1,000 requests.
Two things make the Place Search API worth your attention. First, the quality is comparable to Google Maps, as you will see on the experiment below (which tested a side-by-side comparison of Brave’s Place Search endpoint with 1,000 real queries). Second, Brave’s Place Search API is available at a fraction of the cost of the Google Maps API (which starts at $32 to $35 per 1,000 requests). This makes Brave 6 to 7 times more affordable for comparable place search.
This post details what the API returns, where it’s useful, how it measures up to Google Maps, and why building on Brave’s independent search stack matters.
A single Place Search request returns ranked points of interest with ratings, hours, photos, and distance, on the $5-per-1,000 Search plan. What it doesOne endpoint, accessing an index of about 200 million points of interest worldwide, as well as cities, countries, regions, and streets. This is the backbone of place search in Brave Search, which handles and powers the Brave Search map.
Send a query and a place to look:
curl "https://api.search.brave.com/res/v1/local/place_search?latitude=37.7749&longitude=-122.4194&q=coffee+shops&radius=1000"
-H "X-Subscription-Token: <YOUR_API_KEY>" No coordinates? Use a name instead, such as location=tokyo japan. Drop the query entirely and you get Explore mode: a snapshot of what’s around a point, ideal for map views. It even works without any location hints at all, doing a global search instead.
Every result comes back ready to render:
Name, URL, coordinates, and full postal address Ratings, review counts, price range, categories, and cuisine Opening hours (including today), phone, email, and timezone Photos and distance from your search centerAll these attributes are available on a flat rate of $5 per thousand requests. Compare that with Google, which charges you more for additional attributes.
Need deeper data? Every result carries an id. Pass it to /local/pois for more detail or /local/descriptions for AI-written summaries. The best part: those IDs also come from Web Search results, so one integration covers your local and Web surfaces at once.
You know your product better than we do. So we won’t tell you what to build. But the data is rich enough that one call covers jobs you’d otherwise wire up several APIs to handle:
“Near me” discovery: restaurants, gyms, EV chargers, ATMs. Anchor to coordinates, set a radius, render a ranked list. Travel guides: explore mode plus thecities panel shows what’s worth seeing, then drills into hotels and attractions.
Business directories: try “find a location near you” functionality without licensing a maps stack.
Map dashboards: zoom_level hints and coordinates drop straight into your tiles.
Geofenced nudges: try searches like “three highly-rated lunch spots within 500m.”
AI agents: structured, current place data a model can reason over.
The point is the breadth. Where you take it is up to you.
One Place Search response, four surfaces: a “near me” list, a travel guide, a map view, and structured context for an AI assistant.Note the radius parameter will bias toward an area rather than hard-cutting at the edge. Under ~20 km it gives tight “near me” results. For a famous landmark, go wide or skip it. Match it to the job and results stay clean.
Google Maps is the more mature product, and we won’t claim otherwise.
But the question that matters is whether Brave is good enough to build on, and what you gain by choosing it. To answer it, we ran 1,000 real, global, and multilingual place queries through both Brave and Google Maps. An LLM judge scored every pairing on recall, precision, ranking, and overall quality.
The result: a close second in overall quality: 6.4 vs 7.3 out of 10.
The two engines aren’t tied in character, though. They win in opposite places. That’s the useful part.
Where Brave wins:
Coverage: Brave returns more of the places that actually exist (recall 7.2 vs 6.8). Google often returns fewer. Ambiguous names: Search"africa" near Johannesburg. Brave returns local businesses named “Africa” a kilometer away. Google returns the continent, 2,000 km out. Brave won this query type on recall 8.0 vs 6.1.
Streets and addresses: For queries like "waka sakai line", Google’s place API often returns one far-away result or nothing. Brave returns the right nearby ones.
For the long tail of real local queries (e.g. names, addresses, streets, or anything fuzzy) — Brave is more likely to hand back something useful and close.
Brave vs. Google Maps across 1,000 queries. Overall quality is close(7.3 vs 6.4). Brave leads on recall (7.2 vs 6.8). Google leads on precision (8.2 vs 6.2). They trade strengths.Where Brave trails:
Category ranking: For “kebab near me,” Google floats closer results to the top more reliably. Fuzziness: Broader coverage drags in off-topic results sometimes (precision 6.2 vs 8.2). So who should switch?If you live in the long tail of names, addresses, and streets, or you value coverage, Brave is a strong fit today. If your traffic is mostly clean category search where precision is everything, Google’s Place Search API has an edge, but that edge is small. Try it on your queries.
Considering the price of the Brave Search API, it’s also worth exploring combining Brave and Google options to create an ensemble.
Caveats of the evaluation: The judge of the Brave-vs-Google Place Search API evaluation was an LLM (Opus4.8) which is extremely competent but not free of quirks. For instance, we have seen a bias towards length of the listings, where the judge rewards verbosity even if explicitly instructed not to. Another important caveat not captured by the judge is data-staleness. In that regard, Google has an edge that is hard to beat, as many business owners update changes on opening hours, phone numbers, etc. on the Google Business Profile before they do it on the Web itself. We get the data out of our Web crawler and Web Discovery Project (WDP) signals, which are by definition more limited than the direct input business owners give to Google.
The price difference, in fullBrave is a flat $5 per 1,000 requests, with every field included. And each plan includes $5 in free credit every month.
Google charges per SKU. The endpoints you’d use sit at the top of its price table.
Brave Place Search Google Text / Nearby Search (Pro) Per 1,000 (entry) $5.00 $32.00 (Enterprise: $35.00) Pricing model Flat, all fields included Tiered by SKU and field mask Free allowance $5/month Capped per SKU. Universal $200 credit removedAt the entry tier, Brave is 6 to 7 times cheaper. And that’s before Google’s field-mask tiers push you higher. With Brave, ratings, hours, and photos all ride the same call.
(Google figures are from its official pricing table, 2026. Volume discounts exist for both.)
Built on an independent indexMost search APIs scrape their data from Google. That carries real risk for anyone shipping to customers.
Scraping violates Terms of Service. Google has litigated against providers over it. A scraped feed can be throttled or shut off, and it can’t offer true Zero Data Retention.
Brave is built differently. It runs one of only three independent, global-scale search indexes in the Western world, and the only one outside Big Tech. We own and operate the entire stack, Place Search included. That means:
No scraper risk: Your product does not depend on a service that unofficially scrapes Google, which is subjected to unpredictable quality of service and risk of total discontinuation. Zero Data Retention: Queries aren’t stored, logged, or tied to identities. No conflict of interest: We don’t train our models on your queries. SOC 2 (Type II) attestation: Easier legal and security review. One platform, one set of IDs: Place Search, Web Search, POI details, and AI descriptions share IDs and the same $5/1k plan. If you’re building with AIFrontier models are becoming a commodity. The context you feed them is now what sets your application apart.
Our own research proves it. Ask Brave runs an open-weights model (Qwen) on Brave’s LLM Context API. It goes head-to-head with ChatGPT, Perplexity, and Google AI Mode (and wins) on the strength of better grounding data alone.
Place Search is the local half of that story. An agent that recommends a restaurant or answers “what’s open near me” needs structured, current place data. This endpoint returns exactly that, on the same Search plan as the LLM Context API. Web knowledge and world knowledge, one subscription.
To move faster, the API ships with Skills for Cursor, OpenCode, and Claude Code, plus an API Assistant in the portal that points you to the right endpoint and code.

Seema Amble, Steven Sinofsky, and Elena Burger unpack one of the biggest questions facing enterprise software: what happens when AI agents become the primary users of software instead of humans?
The conversation explores the rise of "headless" software, why APIs and agentic workflows are reshaping enterprise applications, and whether traditional SaaS products are becoming systems of record rather than systems of engagement. They discuss Salesforce's Headless 360 announcement, MCP, enterprise software architecture, and why AI may fundamentally change how businesses interact with their data.
Along the way, they examine what actually makes enterprise software sticky, why replacing systems like SAP and Salesforce is harder than it appears, and where startups have the greatest opportunity as AI reshapes the software stack.

In Decentralized Finance (DeFi), Maximal Extractable Value (MEV) remains one of the most persistent challenges. Searchers and bots scan the public mempool, front-run profitable trades, execute sandwich attacks, and reorder transactions for profit, often at the expense of real users. This erodes trust, increases costs, exposes strategies, and worsens the overall UX in DeFi. Panther leverages Zero-Knowledge proofs to make critical transaction details confidential. Privacy becomes the primary defense against MEV.
Understanding MEV: The Cost of TransparencyOn public blockchains like Ethereum or Polygon, every pending transaction is visible in a shared mempool. Bots detect large swaps, arbitrage opportunities, or liquidations and insert their own transactions to exploit them:
Sandwich attacks: A bot buys before a large purchase (pushing the price up) and sells after. Hence, the bot profits from the volatility caused by the user. Front-running: Copying and executing a profitable strategy ahead of the user. Back-running and other variants: Extracting value from oracle updates, liquidations, or NFT mints. MEV-bots observe your pending token swaps relying on transaction visibilityMEV generates billions in annual value for sophisticated actors while costing everyday users through worse execution prices and slippage. Mitigations like Flashbots or a very high TPS help, but don’t eliminate one of the core drivers of many forms of MEV: public visibility into intent, amounts, and counterparties.
While not all forms of MEV rely on public transaction visibility, reducing information leakage removes one of the most important sources of extractable value. Panther's confidential infrastructure is designed around that principle.
Panther’s Confidential infrastructure: Shielded Pools, Zones, and zSwapPanther's Multi-Asset Shielded Pools (MASPs) form the foundation of the protocol's confidential infrastructure. Users deposit supported assets into Panther's vaults and receive fully collateralized private representations, known as zAssets. These zAssets can then be transferred and used within the shielded environment without publicly revealing transaction details.
Transactions inside the shielded pool use:
zk-SNARKs to prove validity (e.g., “I have sufficient balance”) without revealing amounts, senders, receivers, or links to external wallets. UTXO model with append-only Merkle trees for private state management. Nullifiers that prevent double-spending while maintaining unlinkability. Panther's zSwap allows for private access to public liquidityBecause external observers see only cryptographic commitments and proofs, and not the underlying data, MEV bots lack the information needed to identify and exploit specific trades.
zSwap: Private Access to Public LiquidityFor users needing external DEX liquidity (Uniswap, QuickSwap, Curve, etc.), Panther’s zSwap functionality routes trades privately:
The shielded balance initiates the swap. Stealth addresses and ZK proofs obscure origins and details. Panther minimizes the information exposed before and during execution, reducing opportunities for certain forms of MEV compared with directly trading from a public wallet.Even when interacting with public protocols, the Panther Protocol minimizes information leakage compared to direct wallet-to-DEX trades.
While reducing opportunities for MEV is an important benefit, confidential execution also protects legitimate trading strategies and sensitive transaction information. This is particularly relevant for professional traders, treasury managers and institutions that may wish to avoid signaling large portfolio movements or exposing proprietary trading activity before execution.
Programmable Zones: Controlled Yet Confidential EnvironmentsPanther’s Shielded Pools can be divided into Zones, which are logical partitions of shielded pool liquidity managed by operators, which may include regulated Virtual Asset Service Providers (VASPs), depending on the deployment. Each Zone can enforce custom rules (allowlisted assets/users, KYC attestations, transaction limits) while sharing the pool’s strong anonymity set:
Operators manage permissioned Zones with known counterparties. Compliance tooling can support regulatory requirements while preserving privacy for other participants. Additional Layers of Privacy Protection Growing anonymity set: More users and a more diverse set of assets in the pool make individual transactions harder to distinguish. Non-interactive transfers: zAccounts enable private peer-to-peer movement without revealing EOAs. Economic incentives: Panther Reward Points (PRPs) and the single-sided AMM encourage activity, strengthening privacy over time. Why Confidentiality Matters for MEV ResistanceAs DeFi matures and institutions allocate more capital on-chain, MEV protection becomes necessary for DeFi to scale. Panther improves the UX through its confidential infrastructure by delivering:
Better execution prices. Strategy protection. Reduced systemic risks from MEV. Compliance tooling for operators.Panther combines privacy-preserving technology with configurable AML and compliance tooling, enabling operators to implement risk-based compliance controls while preserving confidentiality and helping to minimize opportunities for MEV extraction.
Conclusion: Privacy Powers Fairer MarketsPanther Protocol demonstrates how confidential infrastructure can make DeFi more secure, efficient and accessible. By reducing unnecessary information leakage, shielded pools and zSwap help reduce opportunities for front-running and other forms of information-driven MEV, while also protecting legitimate trading strategies and sensitive transaction activity. As the protocol expands across different blockchains, Panther aims to provide a confidential infrastructure that supports fairer, more efficient on-chain markets for both individual users and professional market participants.

In this commencement address to Columbia University's Fu Foundation School of Engineering and Applied Science Class of 2015, Ben Horowitz challenges some of the most common advice given to graduates.
Rather than urging students to “follow their passion,” Horowitz argues that people should focus on developing their strengths and making meaningful contributions to the world. Drawing on stories from his own time at Columbia, the founding of technology companies, and investments in startups like Airbnb, he explores the importance of independent thinking, conviction, and pursuing ideas that others may initially dismiss.
Along the way, Horowitz discusses technological progress, entrepreneurship, opportunity, and why he believes today's graduates are entering a world defined less by unprecedented challenges than by unprecedented possibilities.

We are pleased to announce the release of Zebra 6.0.0-rc.0. This release candidate adds Testnet support for the NU6.3 “Ironwood” shielded pool and v6 transaction format, fixes two moderate-severity security issues, ships signed pre-built zebrad binaries for Linux, and includes a state database format upgrade. All node operators are encouraged to test it on Testnet ahead of the final 6.0.0 release.
getblock Verbosity 2 Side-Chain Panic (Moderate)
The getblock RPC at verbosity 2 panicked for blocks not on the best chain: their transactions’ confirmations are negative and were cast to an unsigned type, crashing the node. The fix changes the confirmations field to a signed type, matching zcashd and the rest of Zebra’s codebase.
Thanks to Taylor Hornby for reporting this issue.
GHSA-m9xx-8rcj-vmgp: Per-Peer Mempool Admission Cap Bypass (Moderate)Zebra caps concurrent inbound mempool admissions per peer, but the cap only applied to advertised transaction IDs. Directly pushed transactions (tx messages) bypassed it, letting a single inbound peer occupy more than its share of download slots by pushing full transactions instead of advertising them. This release routes directly pushed transactions through the same per-peer admission accounting. It is the direct-push counterpart to the advertisement-path fix shipped in GHSA-4fc2-h7jh-287c.
Thanks to SuplabsYi of Invariant Labs for reporting this issue.
New Features NU6.3 “Ironwood” Support (Testnet)Zebra now supports the NU6.3 “Ironwood” shielded pool and the v6 transaction format, activating on Testnet at height 4,134,000. The consensus parameters: v6 version group ID, consensus branch ID, and Testnet activation height, match zcash_protocol. No Mainnet activation height is set yet. The z_gettreestate, z_getsubtreesbyindex, and verbose getblock RPCs expose the Ironwood note commitment tree and its subtree roots from NU6.3 activation. (#10762, #10888)
Zebra now tags the coinbase input of every block it mines with a 🦓. As a result, the mining.extra_coinbase_data option is now limited to 86 bytes (previously 94); Zebra refuses to start if the configured value exceeds this. (#10836)
zebrad Binaries
Pre-built zebrad binaries are now attached to each GitHub release for Linux on x86_64 and aarch64, so operators can run a node without Docker or a source build. Binaries are also installable with cargo binstall zebrad. Each .tar.gz carries a SHA-256 checksum, a Sigstore build-provenance attestation, and a Cosign signature over the checksum manifest. (#10799)
A new [notify] block_notify_command option runs a command on each best-chain-tip change, with %s replaced by the new block hash: Zebra’s equivalent of zcashd‘s –blocknotify. (#10726)
When the indexer RPC is enabled, a co-located read-state consumer can now follow the node more efficiently: the non-finalized block subscription resumes from the consumer’s known chain tips instead of re-streaming the whole non-finalized state, and a new GetBlock indexer method lets the consumer fetch blocks it is missing while its finalized state catches up. A new zebra-state read request, ReadRequest::FindForkPoint, returns the most recent block in a caller-supplied locator that is on the best chain, the fork point, for clients tracking chain reorganizations through a read-only state service. (#10776)
A new Regtest configuration option, should_allow_unshielded_coinbase_spends, forbids spending coinbase outputs into transparent outputs: the inverse of zcashd‘s –regtestshieldcoinbase. It defaults to allowing such spends, preserving existing Regtest behavior. (#10698)
A timeout waiting for a transparent input UTXO during transaction verification is now treated as a missing input rather than an internal error, preventing a sync stall near the chain tip. (#10810)
getblocktemplate Coinbase Caching
getblocktemplate now caches the built coinbase transaction per block, so repeated short-poll requests within the same block no longer rebuild it. This prevents CPU saturation and multi-second template latency when mining to a shielded address. (#10847)
The co-located read-state syncer (used by indexers like Zaino) no longer drops and re-creates its non-finalized block subscription every second while its view of the finalized state lags the node’s. (#10818)
invalidateblock / reconsiderblock Edge Cases
Fixed edge cases in invalidateblock and reconsiderblock (chain-root and same-height sibling-tip invalidation, and repeated reconsideration) that could cause a panic. (#10586)
The state database format is bumped to 28.0.0 for the NU6.3 “Ironwood” shielded pool. This is a major-version bump that is restorable in place from the previous major format (no resync required): an in-place migration backfills the genesis Ironwood note commitment tree and anchor, creates four new (initially empty) ironwood_* column families, and widens the chain value pool record to include the Ironwood pool. The getblockchaininfo and getblock valuePools now include the ironwood pool, which will be at zero until NU6.3 activates.
librustzcash crate cohort to the NU6.3 pre-release wave for V6 transactions and Ironwood support. (#10762)
Bumped anyhow to 1.0.103, clearing RUSTSEC-2026-0190. (#10849)
Opening a Zebra state read-only now fails with a clear error instead of panicking when the cache directory is missing or unreadable, when no database exists at the configured path, or when an ephemeral database is also configured. The read-write open path is unchanged.
Other Security Improvements
Zebra’s release Docker images are now reproducible: an independent rebuild of a published zebrad from the same commit produces the same binary. The Rust toolchain and the Rust and Debian base images are pinned by exact version and digest, and build paths and file timestamps are normalized. Release images are also built without the shared build cache, so a published image cannot inherit a layer from a lower-trust build. (#10798)
Release Docker images are signed and carry build provenance and a signed SBOM, so anyone can confirm an image came from Zebra’s CI with cosign verify or gh attestation verify. (#10798)
Zebra now uses a constant-time comparison for RPC cookie authentication. (#10567)
Released zebrad binaries report their source commit in zebrad version. (#10798)
Upgrading
This is a release candidate intended for Testnet testing ahead of the final 6.0.0 release. The state database format upgrade to 28.0.0 migrates in place, so no resync is required. You can find the release on GitHub, crates.io, and Docker Hub.

Containers are now available with today’s update of the Brave browser (v1.92), enabling convenience and ease-of-use for everyday tasks. Containers are a way for users to isolate tabs from one another so that their cookies and storage are not shared outside of the container, even when visiting the same site.
For example, a marketing manager might use containers to be logged into two different social media accounts at the same time. A developer might use containers to test an application with one tab logged in as an administrator and another as a regular user. An employee logged into their Google account might want to open YouTube in a separate container to ensure that their viewing history isn’t linked to their work account.
The original idea for Containers came about at a time when browsers gave different sites the ability to share storage with one another via third-party cookies and similar mechanisms. Since this privacy benefit is already built-in to Brave with storage partitioning (which isolates each site and its third-party requests so that trackers can’t follow you across the Web), containers are best understood as a convenience feature to present different identities to a site and as a basic building block for specific workflows.
To get started, simply go to Settings (brave://settings/braveContent) and click on Enable Containers. You can also right-click a tab, select “Open in container,” and choose the category.
Containers are now built into Brave 1.92 on all desktop platforms (Windows, macOS, and Linux), no extension/add-on needed. Note that this feature is being rolled out in phases over a few days, so if you don’t see it on your platform yet, please check back soon.
Rick Rubin joins Marc Andreessen, Ben Horowitz, Anjney Midha, and Erik Torenberg to discuss creativity, artificial intelligence, and his book The Way of Code, which reimagines the Tao Te Ching for the age of AI.
The conversation explores vibe coding, remix culture, artistic process, entrepreneurship, and what AI changes, and doesn't change, about creativity. Rubin argues that AI is best understood not as a replacement for artists, but as another creative tool, one that expands what's possible while making taste, curiosity, and individual perspective even more valuable.
Along the way, they discuss music, philosophy, startup building, collective intelligence, and why the most enduring creative work begins with staying true to yourself rather than trying to satisfy an audience.

Marc Andreessen joins CSIS's Navin Girishankar for a wide-ranging conversation on artificial intelligence, productivity growth, industrial policy, and America's technological future.
Andreessen argues that while AI has already begun reshaping the economy, the largest impacts are still ahead. He explores how AI could dramatically expand access to expertise, improve productivity, and transform industries ranging from healthcare and education to law and software development. At the same time, he warns that many of the biggest barriers to progress are not technological but institutional, driven by regulation, policy choices, and infrastructure constraints.
The discussion also covers the global AI race, U.S.-China competition, export controls, data centers, energy, reindustrialization, defense technology, and the role of government in fostering innovation. Along the way, Andreessen shares his views on technological progress, national competitiveness, and why he believes America still has an opportunity to lead the next wave of economic growth.

For years, privacy advocates warned that the war against financial crime could gradually evolve into a war against financial privacy itself. What was once dismissed as a slippery-slope argument is now becoming reality in the European Union.
Beginning in July 2027, the EU's new Anti-Money Laundering Regulation (AMLR) will usher in one of the most aggressive regulatory frameworks ever imposed on privacy-preserving financial technologies. Under the new rules, cash payments above €10,000 will be prohibited, anonymous crypto accounts will be outlawed, and regulated cryptocurrency service providers will be effectively forced to remove privacy-focused cryptocurrencies from their platforms. While policymakers frame these measures as necessary tools to combat money laundering and terrorism financing, critics see something far more concerning: a renewed bureaucratic campaign against financial privacy itself.
The attack on privacy coins is particularly significant because it strikes at a fundamental principle that originally inspired cryptocurrency adoption. Bitcoin emerged as an alternative to a financial system increasingly dependent on surveillance, censorship, and centralized control. Yet despite Bitcoin's reputation, its blockchain is entirely transparent. Every transaction can be analyzed, traced, and linked through increasingly sophisticated surveillance tools.
Privacy-focused cryptocurrencies emerged as a technological response to this reality. Projects such as Monero and Zcash were designed to restore the fungibility and confidentiality traditionally associated with physical cash. Their purpose was not to facilitate crime but to protect ordinary users from excessive financial surveillance. Journalists, activists, businesses, political dissidents, and everyday citizens all have legitimate reasons to value financial privacy.
Nevertheless, European regulators have increasingly portrayed privacy-enhancing technologies as a threat rather than a civil liberty. The AMLR reflects this mindset by specifically targeting accounts and services that enable transaction anonymity. Regulators argue that anonymity creates obstacles for law enforcement investigations and increases the risk of illicit finance. From the perspective of Brussels, greater transparency equals greater security.
This argument, however, suffers from a fundamental flaw.
Privacy is not inherently suspicious.
In every other area of modern life, privacy is considered a basic right. Europeans lock their doors, encrypt their communications, and protect their personal information online. Financial privacy should be viewed through the same lens. The assumption that individuals must surrender their transactional confidentiality simply because criminals might exploit privacy tools creates a dangerous precedent.
The irony is particularly striking because the European Union has often positioned itself as a global champion of data protection. Through regulations such as GDPR, Brussels has repeatedly argued that personal information deserves strong safeguards against unnecessary collection and misuse. Yet when it comes to financial transactions, the same institutions appear increasingly comfortable with creating systems of comprehensive visibility and traceability.
The AMLR's treatment of privacy coins illustrates this contradiction. Rather than focusing on criminal activity itself, regulators are targeting technologies that make surveillance more difficult. The distinction is important. A tool that can be abused by criminals is not inherently criminal. Encryption can be used by cybercriminals, yet society recognizes that encryption remains essential for protecting ordinary citizens. Privacy coins deserve similar consideration.
Supporters of the AMLR frequently argue that privacy-focused cryptocurrencies have become obsolete because compliance requirements are now unavoidable. However, history suggests otherwise. Technologies that satisfy genuine market demand rarely disappear simply because regulators disapprove of them. Instead, innovation adapts.
This is precisely where projects like PIVX enter the conversation.
Unlike older privacy-focused networks that have often found themselves at the center of regulatory controversy, PIVX has pursued a more balanced path. Built around advanced Zero-Knowledge cryptography, PIVX seeks to provide users with optional privacy while maintaining the decentralized ethos that defines cryptocurrency. Its shielded transaction technology demonstrates that privacy and innovation can coexist without compromising network security.
More importantly, PIVX represents a broader philosophical challenge to the assumptions underpinning modern surveillance-based regulation. The project recognizes that privacy is not a loophole to be closed but a fundamental human condition that deserves protection. Financial transparency should be a matter of choice, legal process, and due cause—not a default condition imposed upon every citizen.
The European Union's renewed effort against privacy coins may succeed in removing certain assets from regulated exchanges. It may increase compliance burdens and further consolidate oversight within the traditional financial system. What it is unlikely to accomplish is eliminating the demand for privacy itself.
The history of technology repeatedly demonstrates that individuals seek tools that preserve autonomy, confidentiality, and personal freedom. Whether through encryption, decentralized communications, or privacy-preserving cryptocurrencies, innovation tends to move toward empowering users rather than exposing them.
This is why the debate surrounding privacy coins extends far beyond cryptocurrency. At its core, it is a debate about the future relationship between citizens and institutions. Should financial activity become permanently visible to regulators and intermediaries? Or should individuals retain some degree of economic privacy in an increasingly digital world?
The AMLR reflects the EU bureaucracy's answer to that question.
Privacy advocates, technologists, and decentralized communities continue to offer another.
The outcome of this debate will shape not only the future of privacy coins but also the future of financial freedom in the digital age.
ConclusionThe EU's AMLR is being presented as a necessary response to money laundering and illicit finance, yet its practical effect reaches much further. By restricting anonymous accounts, imposing tighter transaction monitoring, and pressuring regulated platforms to delist privacy-focused cryptocurrencies, European policymakers are advancing a vision of finance where surveillance becomes the default and privacy becomes the exception.
The real question is not whether criminals use privacy technologies—they always exploit every available technology. The question is whether ordinary citizens should lose access to privacy because criminals exist.
As July 2027 approaches, the battle over privacy coins will increasingly become a battle over the meaning of financial freedom itself. Projects like PIVX remind us that privacy is not merely a technical feature. It is a fundamental right worth defending in an age where digital surveillance continues to expand.
The renewed effort by EU bureaucrats may slow the adoption of privacy-preserving cryptocurrencies within regulated markets, but it is unlikely to extinguish the broader demand for financial privacy. If anything, it reinforces why privacy technologies remain necessary in the first place.

Renewed Effort by EU Bureaucrats Targeted at Privacy Coin Ban was originally published in PIVX on Medium, where people are continuing the conversation by highlighting and responding to this story.
This post was written by Faheem Nadeem, Senior Search Engineer, Brave Software; Mrinali Umashankar, Partner Solutions Architect, AWS; and Ayan Ray, Principal Partner Solutions Architect, AWS.
Every team faces the same challenge: the information they need to make decisions is scattered across the web, locked in documents, and constantly changing.
Finding information is only part of the problem. Teams also need to ground AI-generated insights in real-time, sourced data while maintaining enterprise security and compliance.
In this post, we dive deep into how we can leverage Claude Cowork on Amazon Bedrock and the Brave Search MCP Server to work together to address this challenge.
We will walk through configuring the Cowork desktop application with Bedrock, and how to add Brave Search as the local MCP server for interactive, user-driven workflows.
Sign up for Brave / AWS webinar
Expanding AI adoption across the organizationClaude Cowork is Anthropic’s agentic AI desktop application. It lets users delegate research, document analysis, data processing, and report generation to Claude. With Cowork on third-party (3P) mode, organizations route all model inference through Amazon Bedrock in their own AWS account. Prompts, responses, files, and tool outputs never leave the customer’s cloud environment.
Organizations across every industry already build with Claude Code in Amazon Bedrock to boost developer productivity and accelerate delivery. With Amazon Bedrock, you build within your existing AWS environment, maintain enterprise security and regional data residency, and scale inference. Your data stays under your account’s controls: Amazon Bedrock does not store prompts, files, tool inputs or outputs, or model responses, and none of this data is used to train foundation models.
Claude Cowork in Amazon Bedrock extends this same trust model to every team in your organization.
What stays the same in Cowork 3P mode
Long-running tasks: Multi-step research, agentic coding, and complex workflows Full Cowork UI: Projects, artifacts, memory, file upload and export, remote connectors, skills, and plugins MCP server support: Connect to external data sources and tools your organization approves Sandboxed execution: Shell commands run in a hardened VM, and file access is scoped to allowed foldersWhat changes
No Anthropic account login required: Authentication flows through IAM or Amazon Bedrock API keys No conversation data flows to Anthropic: Prompts, responses, files, and tool outputs go only to your configured Amazon Bedrock endpoint and are stored only on the local machine Billing through your AWS account: Consumption-based pricing with no seat licensing from Anthropic Centrally managed: All configuration is delivered through your existing MDM (Jamf, Intune, Workspace ONE, or Group Policy) and cannot be overridden by end usersThis architecture is purpose-built for highly regulated enterprises in financial services, government, healthcare, and defense. Amazon Bedrock offers in-Region, geo cross-Region, and global cross-Region inference profiles so you can choose the right level of data residency for your organization.
What you get when you combine Brave Search with CoworkEach component solves a distinct problem. The value grows when you combine the two.
Brave Search MCP Server: Provides real-time web access. Built on Brave’s independent search index of over 40 billion pages, the Brave Search API delivers structured web results, news, local search, and AI-optimized snippets through a standard MCP interface. Claude Cowork on Amazon Bedrock: Provides the agentic runtime. It reads documents, runs multi-step research, processes files, coordinates sub-agents, and returns finished work. All model inference routes through Amazon Bedrock in your AWS account.Used together, these tools can allow enable workflows that:
Ground outputs in current data: Claude synthesizes uploaded documents and supplements them with live web results, so outputs reflect today’s reality rather than stale training data. Verify and cross-reference: Claude can fact-check claims in uploaded documents against current web sources, flag outdated information, and surface contradictions. Fill knowledge gaps automatically: When uploaded documents are incomplete, Claude identifies what is missing and uses Brave Search to fill those gaps with sourced, current information.

George, Lewis, Ben and their team are powering home service businesses across the country, automating operations from office to doorstep.
By Konstantine Buhler Published June 23, 2026 Ben, George and Lewis.There’s no substitute for authenticity. In a world of AI, real, genuine human connection matters more than ever. The story of Probook starts as real as it comes.
After decades on the job, John, a New York City police officer, was injured on duty and couldn’t serve on the force any longer. Some time later, he took up power washing to stay busy and tapped his son, George Eliadis, to help alongside him. George worked weekends and summers in high school, then continued to power wash while he pursued the prestigious M&T dual-degree program at the University of Pennsylvania.
George noticed how much logistics got in the way of what his dad loved most: power washing. Years later, George spent time inside TR Miller, a home services business in Illinois that became Probook’s first customer, and saw the same problems at scale. He learned that what slowed his dad down affected millions of electricians, HVAC techs, plumbers and other workers. The administrative load, from assigning jobs to following up on website inquiries, cuts into already-tight margins and hurts both customer and employee satisfaction.
AI was supposed to take all that on, but reality hasn’t lived up to the hype. Operators bought a tool for every task, and ended up with a stack that couldn’t talk to itself. Nothing connected; costs ballooned. Customer experience stayed broken, and no one’s life got any easier.
George realized his dad’s life—and an entire industry—would benefit from better, more connected software. So he and co-founders Lewis Zhang and Ben Cervantez launched Probook, the AI Operating System for home services—built around dispatch, the foundation everything else depends on. It is a single platform that shares context across the entire customer experience, automating from intake to dispatch and beyond, and expanding margins for the businesses that keep America’s homes running. Probook is personal for George, of course—but it’s not only George who takes this work personally. All three founders are the real deal. Their authenticity shines through, and it’s the reason why we at Sequoia wanted to partner with them from the seed round and now in their Series A.
Probook works like this: your water heater goes out, and you call a local plumbing company that runs on the platform. Probook’s AI picks up immediately, already knowing each technician’s experience, availability and distance from your home, along with their close rates and ticket sizes. It assigns the right tech to the job, alerts them, and keeps you in the loop with an ETA. You get fast help; the company runs leaner; its team earns more with less stress.
Since childhood, George, Lewis and Ben have been scrappy and relentlessly curious. George is a near lifelong entrepreneur—between power washing jobs, he sold everything from coins to vinyl records. He attended Penn’s M&T program along with Ben, who was valedictorian and captain of his high school football team, and interned at McKinsey during college before dropping out to join Probook. Lewis started coding when he was 7, earned degrees in Electrical Engineering and Computer Science from Berkeley in two years, and was part of the critical player-server matching team at Roblox. Dedication is what drives the team: to say they show up for customers is an understatement. They care deeply about tradespeople and are obsessed with taking the drudgery out of their work, flying all over the country to onboard and work with new businesses in person. And for those companies, Probook has been nothing short of life-changing.
Probook’s growing team is scaling quickly, with a mission to transform the trades. When the nerve center of home services is streamlined by AI that actually drives outcomes, operators can run better businesses and build better lives for their staff. We are proud to support George, Lewis, Ben and team.

“Whether it is to be utopia or oblivion will be a touch-and-go relay race right up to the final moment.” — R. Buckminster Fuller
We’re looking for people who put their hand in the box.
If you have a pulse you know we are alive in a moment of extremity, with breakthroughs and breakdowns appearing in equal measure across our civilizational bingo card. The world feels full of potential yet completely off its axis. Yet in this reality, there are those shaping the contours of an unbelievable future in places others can’t fathom. Founders with their eyes wide open to a rapidly changing reality, quietly working on technologies urgently needed to keep us from unravelling, and to nudge us toward a better world.
That’s our mission at BlueYard: to invest in founders building the technologies that move us toward utopia — or hold the line against oblivion. We backed crypto before it was called crypto, we invested in kinetic defense systems when people were still talking dual-use, we invested in AI compute hardware before ChatGPT. AI-powered chemical synthesis, silicon compilers, brain-computer interfaces, AI models for the steel industry, solid rocket motors — that’s our daily context.
We are obsessed with getting there early, putting capital to work in places the herd might not agree with for years. This requires a tolerance for volatility, a mind that can’t be boggled, and the conviction to stand tall when others are in a defensive crouch.
The Investor will have a full-time position on the investment team. From day one, you are out there identifying the best opportunities before they are obvious — meeting founders, attending events, hosting your own, travelling, developing theses, and supporting portfolio companies across key ecosystems worldwide.
You’ll work directly alongside our partners in a small, high-conviction partnership managing $500M in AuM, investing $500K–$5M from pre-seed to Series A. Our sectors span computation & intelligence, engineering & aerospace, defense, biology & chemistry, crypto and whatever is next. If you have a view on where the frontier is heading — we want to hear it.
The role includes:
Identifying the technologies and trends that will reshape economies and societies, and represent attractive early-stage venture opportunities Carrying out market, company, and technical due diligence on investment opportunities Working with our portfolio companies and networks to support themWho we’re looking for. People who go unreasonably deep on things that fascinate them. Who form their own views and can defend them when the room disagrees. Who don’t wait for instructions — they see what needs to happen and make it happen.
You might be an engineer, a scientist, an economist, a builder, or someone who defies categorization entirely. What matters is intellectual horsepower, founder empathy, and the ability to evaluate founders and complex technologies across unfamiliar domains. You understand that the most interesting opportunities look strange at first — and that’s precisely why they’re interesting.
We’re open to early-career professionals with 2–3 years of experience, or graduates who can prove they gained necessary experience through entrepreneurial experiences or extended and relevant internships. We’re equally open to more experienced candidates — and we’ll shape the role around the person. No prior VC experience is required. What we need is intensity, range, and a restless need to understand how the world actually works.
Here’s what we’d like you to bring:
Intellectual horsepower and genuine range across technical and scientific domains The ability to clearly articulate views on markets, companies, and technologies, both written and spoken A self-(fire)starter who can run on their own, identify opportunities, and prioritize without much guidance Strong interpersonal skills and real founder empathy Native (or close to) English language skills, written and oral The willingness to roll up your sleevesSomewhere along the way, venture capital became addicted to templates and already-obvious startups. We think the best returns — and the best careers — live where deep risk and real opportunity overlap. If that excites you more than it scares you, we should talk.

What the Recent Zcash Incident Teaches Us About Privacy Infrastructure
Privacy technologies are among the most sophisticated innovations ever introduced into blockchain systems. They solve one of cryptocurrency's oldest contradictions: how can a public ledger preserve user confidentiality while remaining verifiable by everyone?
The answer has largely come through Zero-Knowledge Proofs, particularly zk-SNARKs. Yet the recent vulnerability disclosed within Zcash's Orchard shielded pool reminds us that advanced cryptography, while powerful, is not immune to implementation risks. The incident serves as a valuable lesson for the broader privacy ecosystem and highlights why continuous auditing, transparency, and protocol evolution matter more than ever.
For the PIVX community, the event also offers an opportunity to examine how PIVX’s privacy architecture has been built with long-term resilience in mind.
The Orchard Vulnerability: A Wake-Up Call for Privacy Networks
In early June 2026, developers and researchers disclosed a critical vulnerability within Zcash's Orchard shielded pool. The flaw reportedly existed within the proof system responsible for validating private transactions and, under certain circumstances, could have enabled the creation of counterfeit ZEC without immediate detection. Fortunately, the issue was identified before any known exploitation occurred, and emergency network upgrades were deployed to remediate the problem.
While no user funds were compromised and no evidence of unauthorized coin creation was found, the incident demonstrated an uncomfortable reality: privacy protocols are only as secure as their underlying implementations. Even mathematically sound cryptographic systems can become vulnerable when complex codebases evolve over time.
Why the Incident Reinforces Confidence in PIVX
The recent Zcash vulnerability does not prove that one privacy protocol is superior to another. What it does reinforce is the importance of diversity, independent implementations, and continuous review.
PIVX benefits from several reassuring characteristics:
First, its SHIELD implementation is not a direct copy of Orchard. The architecture and code pathways differ significantly, reducing exposure to identical implementation risks.
Second, PIVX operates within a mature Proof-of-Stake ecosystem where community governance actively funds development, testing, and protocol maintenance. This decentralized oversight creates incentives for ongoing security improvements.
Third, PIVX has historically taken a measured approach to privacy deployment. Rather than pursuing rapid feature expansion at any cost, development has often prioritized stability, usability, and long-term maintainability.
ConclusionThe recent Zcash Orchard vulnerability should not be viewed as an indictment of privacy technology. Instead, it should be seen as a reminder that innovation requires constant vigilance.
Privacy remains essential in a world where financial surveillance is becoming increasingly normalized. Zero-Knowledge Proofs remain one of the most powerful tools available for protecting individual freedom on public blockchains. The challenge is ensuring that these systems are implemented, maintained, and audited with the highest possible standards.
PIVX's SHIELD protocol represents more than just a privacy feature. It represents a long-term commitment to secure, sustainable, and user-controlled financial privacy.
As the industry learns from every challenge and every disclosure, PIVX continues to demonstrate why responsible privacy innovation is not merely about hiding information, it’s about preserving trust.
PIVX. Your Rights. Your Privacy. Your Choice.

We have recently released Zebra 5.2.0. This release ships a robustness improvement that was merged to main after the 5.1.1 maintenance release: a significantly wider local rollback window to defend against consensus splits.
All node operators are encouraged to upgrade. Nodes running Zebra 5.1.1 or earlier will reach end-of-support on approximately July 25, 2026, ahead of the expected NU7 network upgrade.
New Features Wider local rollback window (MAX_BLOCK_REORG_HEIGHT 99 → 1000)
Zebra’s local rollback window — the maximum number of non-finalized tip blocks Zebra will retain in memory, ready to reorganize — has been increased from 99 to 1000 blocks (#10650).
This is a defense-in-depth measure motivated by real-world incidents on other chains. A reorg window of 99 blocks covers roughly 99 minutes at Zcash’s one-block-per-75-seconds pace. A 1000-block window provides coverage for reorgs of up to approximately 20 hours, giving node operators and network participants substantially more time to respond to a sustained consensus split.
This change is the primary reason for the minor-version bump: MAX_BLOCK_REORG_HEIGHT is a public constant exported by zebra-chain, and its value changed ten-fold, affecting both memory usage (the non-finalized state may now hold up to 1000 blocks in RAM instead of 99) and any downstream consumers that import the constant directly.
To upgrade to Zebra 5.2.0, install it with:
cargo install --git https://github.com/ZcashFoundation/zebra --tag v5.2.0 zebrad
Or update via your package manager if you are using a pre-built binary.
Zebra 5.2.0 nodes will stop around July 25, 2026, approximately 37 days after the estimated release height. We plan to release a further update ahead of the expected NU7 network upgrade. Keep an eye on the Zcash Foundation blog and the Zebra repository for announcements.

Public blockchains were designed for transparency. Every transaction, wallet interaction and asset movement can be viewed, analyzed, and stored indefinitely.
For years, this transparency was often seen as a feature. Today, advances in artificial intelligence are changing the equation.
AI has made blockchain analytics faster, cheaper and more powerful. Information that once required specialist tools and significant effort to analyze can now be processed at scale. Wallet activity can be clustered, patterns identified, and behavioral profiles built more efficiently than ever before.
As crypto moves toward mainstream adoption, privacy is no longer just a personal preference. It is becoming a prerequisite for individuals, institutions and businesses that want to participate in onchain ecosystems without exposing every aspect of their financial activity to the world.
Why Privacy Matters for DeFiThe promise of decentralized finance is open access to financial services. But open access does not necessarily require complete transparency.
In traditional finance, transaction histories, trading strategies, balances and counterparties are not published for anyone to inspect. In contrast, most blockchain activity is visible by default.
This creates several challenges.
Protecting Financial ConfidentialityEvery onchain interaction contributes to a permanent public record. Traders, investors, businesses and institutions may not want competitors, counterparties or third parties analyzing their activity in real time.
As analytics tools become increasingly sophisticated, maintaining confidentiality becomes more difficult. Privacy infrastructure helps users decide what information they share and what information remains private.
Reducing Profiling and Wallet TargetingPublic wallet activity can be used to build detailed profiles of users, including transaction habits, asset holdings and behavioral patterns.
For high-value wallets, active traders and institutions, this visibility can create additional risks. Privacy-preserving infrastructure makes it more difficult to link activity, follow asset movements and build comprehensive profiles based on public blockchain data.
Supporting Real-World AdoptionMany organizations cannot operate effectively if every transaction, balance change and commercial relationship is visible to the public.
For decentralized finance to support broader adoption, users need tools that provide confidentiality while preserving the benefits of public blockchain infrastructure.
How Panther HelpsPanther Protocol is designed to provide configurable privacy for onchain activity.
Rather than requiring users to choose between complete transparency and complete opacity, Panther aims to give users greater control over how their onchain activity is exposed.
Using Zero-Knowledge proofs, Panther enables users to interact with privacy-preserving infrastructure while maintaining control of their assets and transactions.
Panther's architecture breaks the onchain link between source and destination Multi-Asset Shielded PoolsPanther allows users to deposit supported assets into shielded pools and receive corresponding privacy-preserving representations of those assets.
Within the shielded environment, transactions can be conducted without exposing the same level of information that would typically be visible on a public blockchain.
This helps break the direct link between public wallet activity and subsequent transactions, making large-scale profiling and behavioral analysis more difficult.
Privacy-Preserving ArchitecturePanther uses a UTXO-based model within its shielded environment to help reduce the ability of third parties to link transactions together.
Rather than exposing a single persistent transaction history to public observers, the architecture is designed to make blockchain analysis significantly more challenging.
Programmable Privacy ZonesDifferent users have different requirements.
Institutions, businesses and communities may wish to operate within environments that apply specific participation criteria, asset restrictions or operational rules.
Panther's Privacy Zones are intended to support configurable environments while allowing participants to benefit from the broader privacy set of the protocol.
User-Controlled DataPrivacy is not simply about hiding information. It is about controlling access to information.
Panther's architecture is designed around the principle that sensitive information should not be publicly exposed by default.
Identity verification and compliance-related processes can be performed by independent third-party providers without requiring personal information to be published onchain.
This approach helps reduce unnecessary disclosure while allowing ecosystem participants to build services that align with their own operational and regulatory requirements.
Privacy and AI Are ConvergingThe combination of transparent blockchains and increasingly capable AI systems is creating new challenges for digital privacy.
As analytics become more powerful, public blockchain data becomes easier to interpret, correlate and utilize at scale.
The question is no longer whether blockchain data can be analyzed. It is how much information users should be required to reveal in order to participate.
Privacy-enhancing technologies help restore balance by giving users greater control over their information while preserving the openness, security and composability that make public blockchains valuable.
As onchain ecosystems continue to mature, privacy is likely to become an essential part of blockchain infrastructure rather than an optional feature.

Zcash Foundation (ZF) is pleased to announce that Zcon7 will take place October 27–29, 2026 at an all-inclusive resort in Cancún, Mexico. Applications to attend are now open.
This year’s gathering coincides with a significant milestone for our ecosystem: Zcash’s 10th birthday on October 28th! Ten years of shielded transactions, zero-knowledge research, and a global community committed to financial privacy. We look forward to marking the occasion with the people who have built and sustained the protocol.
What to expectZcon7 will be an in-person only event. This format reflects our belief that the most valuable elements of Zcon — collaborative working sessions, hallway conversations, and the partnerships that emerge from them — are best supported in person.
Programming will include technical sessions, governance discussions, and community gatherings, with ocean-view group dinners in the evenings. The program is being developed in cooperation with other ecosystem contributors to ensure a diverse and engaging lineup. Speakers and sessions will be announced in late summer.
How to applyThe Zcon7 Application Form is now available! We are excited to share that there is absolutely no cost for the conference ticket. We want Zcon to remain accessible to everyone in the community, and not charging a ticket fee is central to that commitment. Please keep in mind that submitting the form is an application to attend, rather than a confirmed registration. Because event capacity is limited, ZF will begin reviewing applications in July, so we ask that you hold off on booking any flights until you receive an official acceptance email.
To secure your spot:
Submit your application — Fill out the Zcon7 application form. The conference ticket is completely free, but please note that submitting the form is an application to attend, not a confirmed registration. Wait for ZF’s review — Because event capacity is limited, ZF will begin reviewing applications in July. Please hold off on booking any flights until you receive an official acceptance email. Book your room through the official ZF link — If accepted, your acceptance email will include an exclusive group reservation link for the all-inclusive resort. You must use this specific link. Per resort regulations, guests who book directly with the hotel or through third-party vendors will not receive a conference wristband and will be unable to participate in the conference or any associated events. Plan your stay — Accepted attendees are responsible for their own accommodation costs and are required to stay at the Zcon7 venue resort. Room rates are $312.88 USD/night for single occupancy and $357.62 USD/night for double occupancy. We recommend a four-night stay from October 26th through October 30th. ScholarshipsZF offers Zcon7 scholarships to support community members whose contributions are vital to the Zcash ecosystem and who require financial assistance to attend. Scholarships will cover up to $1,000 USD in travel expenses, private airport transportation, and four nights of lodging at the resort. To apply, select “Zcon scholarship applicant” as your role on the application form. The scholarship application deadline is June 29, 2026 at 23:00 UTC (7:00 PM ET). Space is limited.
Venue confidentialityFor the safety of speakers and attendees, we are not publicly disclosing the resort name or precise location. We ask that community members exercise discretion when sharing these details. Accepted attendees will receive all relevant information directly.
Looking aheadTen years into the Zcash protocol, the work of building meaningful financial privacy continues. Zcon7 is where contributors, researchers, and community members convene to share progress, surface challenges, and chart the path forward. We encourage everyone whose work intersects with the Zcash ecosystem to apply.
For the complete FAQ and additional details, please visit the Zcon7 webpage.

Today, we opened a SIV poll of the Zcash Community Advisory Panel (ZCAP), which will run until Monday, June 29th, 20:00 UTC. The purpose of this poll is to fill two seats on the Zcash Community Grants committee (ZCG).
Elections to the Zcash Community Grants CommitteeMembers of the Zcash Community Grants (ZCG) committee are elected by the Zcash Community Advisory Panel and serve a one-year term. Two of the current members’ terms are expiring at the end of June: Decentralistdan and GGuy. Last month, FPF invited candidates to express their interest in serving on the committee.
Fourteen candidates are standing for election. Here is the list of candidates, with links to their candidacy announcements on the Zcash Community Forum:
Dontbeevil Aesobar (Michael) Paul Brigner Victor Zscharnt (Vic) Decentrathai USCMigs (Miguel) Ready Mouse (Mylo Bennett) Valens gorusys (Daniel Goh) T.S. (vaspholdings) GGuy M.F Palmar GroggsCandidates were invited to post a video or text response addressing the most upvoted questions, available in this thread.
As with previous polls, this election will be decided by approval voting. The two candidates with the most approval votes will become the new ZCG committee members on July 1st.
ZCAP members should check their mailbox for instructions on how to vote from election@siv.org. In the past, SIV emails have sometimes been flagged as spam, so if you can’t find the instructions please check your Spam folder.
Good luck to all the candidates, and thank you for volunteering to serve on the ZCG committee!
The post ZCAP Poll Now Open: ZCG Election – June 2026 appeared first on Zcash Foundation.
We are releasing Zebra 5.1.0 today. This release resolves a long-standing genesis-to-tip sync stall that could leave nodes stuck mid-sync, raises the minimum network protocol version to NU6.2, and extends the getpeerinfo RPC with additional peer metadata. All node operators are encouraged to upgrade.
Zebra now requires all peers to negotiate at least the NU6.2 protocol version (170150). Peers advertising an older version will be rejected at connection time. This ensures Zebra only connects to nodes that support the rules introduced with the NU6.2 network upgrade, and reflects the current state of the Zcash mainnet peer population. (#10692, #10704)
deferred_pool_balance_change Removed from Block Types
The deferred_pool_balance_change field has been removed from ContextuallyVerifiedBlock, SemanticallyVerifiedBlock, and CheckpointVerifiedBlock. The value is now calculated on demand rather than stored on the block struct. Code that accessed this field directly will need to be updated. (#10392)
getpeerinfo RPC
The getpeerinfo RPC response now includes additional peer metadata, giving node operators and mining software richer diagnostic information about connected peers. (#10443)
A long-standing bug (#5709) could cause Zebra to stall part-way through an initial sync from genesis. The stall occurred because repeated tip-reset events were not handled correctly, leaving the node waiting indefinitely for blocks it would never receive from the current peer set. This release tackles the symptoms of the underlying timing issue, allowing a full initial sync to complete reliably. (#10679)
getrawmempool Performance
The getrawmempool RPC previously rebuilt the mempool transaction index once per transaction when formatting the response. The index is now built a single time per call, which meaningfully reduces response latency on nodes with large mempools. (#10599)
dequeue_children Index Handling
A bug in the non-finalized state’s dequeue_children by-height index could produce incorrect index entries under certain block sequencing conditions. This has been corrected. (#10604)
Internal ImprovementsThis release includes several improvements to Zebra’s CI pipeline that strengthen the reliability of the development workflow:
Required status checks can no longer pass before all tests have finished running. Previously, the Mergify merge queue could advance PRs before unit tests completed, allowing failing tests to slip through undetected. (#10637) Fixed a block-tip race condition in thegetblocktemplate integration test that had been causing intermittent CI failures since late May. (#10702)
Restored main branch CI checks that had been broken. (#10700)
Upgrading
We encourage all Zebra node operators to upgrade to 5.1.0. The sync stall fix is particularly impactful for operators running a full initial sync — if your node has ever stalled before reaching the chain tip, this release addresses the underlying cause. You can find the release on GitHub, crates.io and Docker Hub.
Thank You to Our ContributorsThis release was made possible by the work of @conradoplg, @gustavovalverde, @judah-caruso, @oxarbitrage, @syszery, and @upbqdn. Thank you for your continued contributions to Zebra.
