Bitcoin, with its 21 million coin cap, is a sustainable store of value. Ethereum, with EIP-1559, is a sustainable medium of exchange. Zcash is about to have both. It already has a 21 million cap, and with ZIP-235’s upcoming transaction fee burn, it becomes a sustainable medium of exchange.

Announcing Zypherpunk! We are calling up builders, researchers, and creators to come and shape the future of Zcash. Our aim is to create an entry point for new talent in Zcash, where they can learn, contribute, meet like-minded people, and also get rewarded for their efforts. Dozens of developers are already contributing via Zypherpunk with projects like thus-spoke-zakura, and more are being created as we speak. We will be focused on the following: - building more projects like thus-spoke-zakura collaboratively with developers - creating content and media that accelerates developer-focused education for Zcash - events and meetups that bring more high-quality technical talent to Zcash - hackathons to identify the next big projects for Zcash and help them find the right partners for mentoring, funding, etc. The encrypted money for humanity needs the brightest minds of our generation building for it. If this sounds interesting to you, please fill out the form to join our Discord below 👇

If you're looking to see how @ZCash is working to solve hard problems like scaling, post quantum, etc... give this 50 MIN (you heard right) video a watch as it's thorough in explaining the goal w/ @TachyonZcash . ZCash team committed to doing the hard work!
We condensed Tachyon’s design into a video that walks anyone familiar with Zcash’s protocol through each change.

Today I call upon the blockchain industry to calmly begin planning for "bunker mode". My personal recommendation is to set in motion a controlled mass migration of assets to fresh addresses, i.e. addresses whose pubkeys remain hidden behind a hash. Holders, starting with large and sophisticated ones, should consider moving the bulk of their funds to addresses that have never signed a transaction. And when they do sign one, they should also move remaining funds to a new address (possibly generated from the same seed phrase). Don't rush. While I believe there is cause for action a rushed migration would do more harm than good. Don't panic either. Moving assets to protected addresses is a simple, preventative step which does not require new cryptography or new wallets. IMO it is now reasonable to brace for the possibility that ECDSA breaks before qday, in the worst case in months not years. By "break" I mean fast private key recovery (e.g. in one week) on available hardware (e.g. a large GPU cluster). Recent days have been humbling for human mathematical intuition. Long-held, unquestioned hypotheses have fallen. This includes the n log(n) bound for integer multiplication and the 3SUM conjecture. In hindsight, May's unexpected disproof of the Erdős unit distance conjecture was our warning shot. Yesterday's OpenAI drop made it clear that mathematical superintelligence is upon us. They say there are weeks where decades happen. We are about to live through weeks where centuries of mathematical progress happen. Could our magic 64-byte ECDSA signatures be too good to be true? Was it just security through obscurity all this time? Elliptic curves feel especially vulnerable to superintelligence. Curves carry rich structure, with room for fancy tricks like Schoof, Frobenius, pairings. (By contrast, hashes are designed to minimise algebraic structure.) Separately, as Ewin Tang can attest, an efficient quantum algorithm sometimes foreshadows an efficient classical one. We should be open to the possibility of a classical counterpart to Shor that breaks elliptic curves and RSA at once. Also noteworthy is the striking under-representation of cryptographic breakthroughs among the 722 mathematical results OpenAI published. I've witnessed first-hand the US government censoring academic quantum cryptanalysis results. Backroom interventionism is my base case. I urge large, sophisticated actors to lead by example. Project11's "risq list" (bitcoin-risq-list.projecteleven[.]com) is a great tracker of exposed BTC pubkeys. Binance, Bitbank, Robinhood, Bitfinex, and Tether have an opportunity to harden their cold storage. Next month I'll address institutions in London in a live Q&A (forum.ethereuminstitutional[.]org/london-2026). Again, please do not rush. Wallets holding under 50 BTC enjoy partial cover from "Satoshi's shield", i.e. his 20K exposed addresses that hold 50 BTC each. Load-bearing signers like oracles and L2 security councils should consider rotating ECDSA pubkeys with every signed message and/or multi-signing with a hash-based schemes like SPHINCS. Exiting bunker mode safely will require post-AI cryptography. My inclination is to go all-in on hash-based cryptography and avoid structured mathematical assumptions entirely, whether from curves, lattices, or isogenies. A single battle-tested hash (e.g. from the SHA or BLAKE families) yields plausible post-AI security. The Ethereum roadmap on strawmap[.]org fully embraces hash-based cryptography with end-to-end formal verification as a response to the quantum threat. Those timelines must now be revisited and accelerated in light of mathematical superintelligence. I'll be pushing for maximum defensive acceleration.

Today we’re launching Strongpoint, Project Eleven’s institutional custody solution built for the post-quantum and AI era. Zcash Foundation joins as an initial development partner as we build crypto-agile custody infrastructure for a world where blockchains implement different cryptography on different timelines. Learn more: projecteleven.com/strongpoin…
Project Eleven Launches Strongpoint for Post-Quantum Custody with Zcash Foundation as Initial Development Partner Zcash Foundation joins Project Eleven to shape institutional custody infrastructure for the post-quantum and AI era as more than $1 trillion in digital assets remain at risk of attack by sufficiently powerful quantum computers. Project Eleven, the post-quantum security company for digital assets, today introduced Strongpoint, its flagship custody platform built for navigating the transition to post-quantum cryptography. @ZcashFoundation joins Project Eleven as an initial development partner, helping shape Strongpoint’s institutional custody architecture. Strongpoint is designed to give institutions a consistent control layer for securing and managing digital assets as networks change the cryptographic standards underneath them. Rather than rebuilding key-management, transaction approval, and audit infrastructure for each new signature scheme or network migration, institutions can maintain a common set of security controls while the underlying cryptography evolves. “Institutional digital asset custody was built for a world where the cryptography underneath it rarely changed,” said Alex Pruden, CEO of Project Eleven. “Quantum computing is upending that model. If every network adopts a different solution, institutions could be forced to rebuild their security infrastructure again and again. Strongpoint is built around crypto-agility, so the cryptography can change without the infrastructure changing with it.” “Institutions holding shielded ZEC need custody infrastructure that respects Zcash’s privacy model today and can adapt as cryptographic standards change,” said Alex Bornstein, Executive Director of Zcash Foundation. “Project Eleven is building Strongpoint with the crypto-agility and technical foundation needed to support those requirements over time, helping strengthen custody infrastructure for the broader ecosystem.” Zcash Foundation Joins as an Initial Development Partner Zcash Foundation joins as an initial development partner for Strongpoint, bringing its expertise in privacy-preserving cryptography and protocol engineering to Strongpoint’s institutional custody architecture. Zcash’s privacy-preserving design introduces sophisticated key-management and transaction requirements, making it a valuable environment for developing custody infrastructure capable of supporting evolving cryptographic standards. The collaboration will help inform how Strongpoint handles network-specific requirements while maintaining a consistent institutional control framework across assets and cryptographic schemes. Post-Quantum Migrations Are Taking Different Paths The digital asset industry’s post-quantum transition is becoming a coordination challenge. Among the networks represented by the 20 largest assets in CoinGecko’s Layer 1 (L1) category by market capitalization, Project Eleven found that only 10 have published a network-specific technical proposal, roadmap or implementation path for migrating transaction or account authentication to post-quantum cryptography. Those approaches span at least six proposed post-quantum signature schemes and vary significantly in how they address account migration, key rotation and legacy-asset recovery. Even where technical roadmaps exist, operational readiness remains uneven, leaving institutions to navigate different standards and requirements across networks. For institutions operating across multiple networks, that fragmentation means accommodating different cryptographic standards and migration requirements without losing a consistent security model. Strongpoint is designed to provide that common operating layer while allowing the cryptography beneath it to change independently. Early Access and Deployment Project Eleven targets production deployment in Q4 2026 and is working with a limited group of development partners ahead of general availability. Additional development partners and supported networks will be announced. Institutions interested in early access can request more information at projecteleven.com/strongpoin…. Founded in 2024 by Alex Pruden and Conor Deegan, Project Eleven raised a $20 million Series A led by Castle Island Ventures in January 2026, bringing its total funding to $26 million. The company recently acquired Riva Labs, a specialized engineering firm with deep expertise in post-quantum signatures, wallet infrastructure and blockchain cryptography, expanding Project Eleven’s in-house research and protocol-engineering capabilities. Methodology: Project Eleven reviewed the 20 largest assets in CoinGecko’s Layer 1 (L1) category by market capitalization on September 25, 2026. A network was counted only where an official network organization, foundation, core development team or recognized protocol-improvement process had published a network-specific technical proposal, roadmap or implementation path for migrating transaction or account authentication to post-quantum cryptography. General research programs, statements of intent and post-quantum work that did not specify such a migration path were not counted. Draft technical proposals were included and do not imply network approval or adoption.
