Google, 5 days after publishing their 2029 timeline for post-quantum cryptography migration, announced quantum computers will be able to steal crypto in 9 minutes. That means every Bitcoin transaction is at risk. Wake up. Migrate to PQC. Or this beautiful experiment is over.
🚨 Google has sounded the quantum alarm 🚨 Today, they released groundbreaking progress towards breaking crypto using a quantum computer. TLDR - Existing cryptography is dead. Mempool attacks are real. We must migrate to post-quantum now. Thread 🧵

Project Eleven grows more powerful by the day.
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.

It doesn't mean we are doomed. It means we have to follow best security practices like the rest of critical internet infrasructure and migrate to post-quantum cryptography. This is a great conclusion (even tho I disagree with the article headline and the "not imminent" part).

While developing CUTS, we have spent a significant amount of time working out which criteria are the right ones for evaluating schemes of this kind. Some metrics are obvious, particularly when digital assets are the intended use case. Signature size, signing cost measured in hash evaluations and security level in bits are where any comparison starts. But comparing those metrics one by one can obscure important differences in how a scheme actually behaves. One less obvious angle of analysis is the distribution of security across reused keys, and in particular its weak tail. Concretely, take a scheme in which each key is designed to sign safely twice, and assume that key has already produced both signatures. How does the security left to that key depend on which two signatures it happened to produce, and how often does it fall well below the published figure? The figure published for a scheme is often an average over all possible pairs of signatures, but each pair overlaps in a different way, exposing different amounts of information to a forger, and some pairs expose far more than others. The chart below shows that schemes sharing most of their building blocks can still differ significantly in how far below the average their weakest keys fall. It plots two few-time schemes, A and B, at parameter sets that give both practically the same average security after two signatures. Close to the average, A has more weak keys than B. Further into the weak tail, the curves cross and the order reverses: Scheme B features rare keys whose security falls far below the average, while Scheme A has considerably less in this region. For a given user, the probability of suffering a potentially catastrophic forgery depends on the computation an attacker can spend against that key and on the security the key retains after its two signatures. Looking only at the average therefore makes the two schemes appear similarly secure for a randomly selected reused key. The picture changes once many reused keys are visible, because anyone can compute a key's remaining security from its two public signatures and an attacker will go after the weakest key first. The more reused keys there are onchain, the more likely it is that one shows up deeper in the weak tail. The two schemes in the chart use comparable parameter sets and still end up with noticeably different results. A difference of this kind in the security profile can carry significant weight in design decisions, since users of a system or network, given the choice, are likely to accept slightly more expensive signatures in exchange for lower exposure to catastrophic failure, especially when those signatures protect digital value. Much of our work on CUTS and related schemes goes into understanding tradeoffs like this across the broader few-time signature design space. Signature size, computational cost, and headline security levels are useful metrics, but none tells the whole story on its own. The details of how security behaves in practice can matter just as much when evaluating a scheme for real-world deployment. The CUTS paper, with the full specification and security proofs, will be published soon.
Introducing CUTS (Chained Uniform-sum Tree Signatures), a new few-time hash-based signature scheme from our research team at Project Eleven. Hash-based signatures are one of the most conservative paths to post-quantum security. Their security rests only on hash functions, but that simplicity comes at the cost of larger signatures. The most compact schemes reduce that cost by using one-time keys, which become vulnerable if they are ever reused. Restore an old backup or load the same seed onto two devices, and a one-time key can end up signing twice. A WOTS+C key that has signed twice keeps only about 34 bits of security. One GPU can then forge a new signature in under a second. By contrast, few-time signatures are built to handle reuse, but they are larger. FORS, the few-time construction inside SLH-DSA, needs more than 2 KB per signature at 128-bit security. CUTS targets the middle ground: more security after reuse, at sizes close to one-time signatures. It arranges hash chains in a tree, and the message hash picks which chains each signature reveals. When a key signs twice, the two signatures usually expose different parts of the key. At 546 bytes, close to one-time size, a CUTS key keeps 53 bits of security after two signatures. At 1,360 bytes it keeps the full 128 bits. That is 41% smaller than any FORS parameter set at that security with practical key generation. At 2,128 bytes, CUTS is smaller, faster to verify and cheaper to generate than every FORS parameter set we compared, including the one in SLH-DSA-128s. The aim is hash-based signatures that hold up in systems where accidental key reuse can happen. The parameters let each application trade signature size, verification cost, key generation and security after reuse against each other. The paper, with the full specification and security proofs, is coming soon. These figures come from our current analysis, and the parameter sets and numbers in the paper may differ. We'd love feedback, from improvements to attacks. Reply or get in touch.

Project Eleven grows more powerful by the day.
Project Eleven Acquires Riva Labs to Expand Post-Quantum Research and Engineering Riva Labs joins Project Eleven as the company brings more specialized post-quantum talent and technology under one roof. Project Eleven, the company building post-quantum security infrastructure for digital assets, today announced its acquisition of @riva_labs, expanding its expertise in post-quantum signatures, wallets, MPC, and account abstraction. The acquisition also brings technology and intellectual property developed through Riva's work across Ethereum and other public blockchains, adding to Project Eleven's capabilities in post-quantum cryptography and blockchain infrastructure. Riva Labs has built a reputation for translating post-quantum cryptographic research into practical blockchain systems. Its work spans hash-based post-quantum signatures, post-quantum MPC, account abstraction, wallet infrastructure, and hardware signing, including recent demonstrations of post-quantum signing on consumer hardware. The addition of Riva expands Project Eleven's research and engineering bench as the digital asset industry prepares for the complexity of post-quantum migration. Rather than treating signatures, wallets, key management, and protocol infrastructure as separate problems, Project Eleven is bringing together expertise across each layer required to make that transition practical. That work is becoming more urgent as AI accelerates cryptographic research and cryptanalysis, allowing new techniques to be developed, tested, and challenged at greater speed. Riva has made AI a core part of its research and engineering process, bringing that capability into Project Eleven's work across post-quantum cryptography and crypto agility. "Riva Labs is exactly the kind of talent we want at Project Eleven: deeply technical and focused on turning cryptographic research into systems that can actually be deployed," said @apruden08, CEO and Co-Founder of Project Eleven. "Bringing Riva into Project Eleven strengthens an already exceptional research and engineering team, adds valuable technology, and accelerates our ability to lead the transition to post-quantum security across digital assets." "Project Eleven and Riva Labs came at this problem from different directions and reached many of the same conclusions about what the industry needs," said @matteovena, Co-Founder of Riva Labs. "Upgrading the public networks the future will run on, without compromising the properties that make them valuable in the first place, is a monumental challenge. Our focus is on giving the industry the tools to accelerate that transition, and joining Project Eleven lets us do it at a much larger scale." The Riva team and technology will become part of Project Eleven's broader research and product efforts across post-quantum cryptography, digital asset custody, and blockchain security. The acquisition deepens Project Eleven's technical capabilities as it builds the infrastructure required for a secure post-quantum transition.
