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.

We formally verified 123 open-source projects in a partnership with Anthropic. Formal verification at scale is here! Now we’re launching OSS Verify to scale it to the software we all depend on. We prove it’s crash-free or send you the patches it needs. Free for open-source. Let’s bootstrap the verified software ecosystem: theorem.dev/oss-verify

A concept (pattern) you should know about: * Concentration Is What Turns the Beneficial Toxic , wiki.p2pfoundation.net/Conce… Cameron Burgess et al. : "There’s a pattern here that nature already knows: concentration is what turns the beneficial toxic. Manure spread thin feeds a field; piled up in an industrial feedlot it poisons the watershed. Water that soaks in nourishes the soil; channelled into a torrent it strips it bare. Data is no different — the reflex to centralise everything doesn’t just create a single point of failure, it concentrates what was never meant to pool until the flows themselves turn destructive. Step back from the individual headlines and the pattern is singular. The AI security exposure, the quantum shelf-life problem, the regulatory reckoning, the sovereignty scramble — these are not separate crises. They are the same crisis surfacing in different domains: too much concentrated in too few centres, on infrastructure that was never built to keep it safe. Every one of them points to the same answer — and it’s not a better centre. It’s no centre at all." (decent.holoventures.io/02-th…)

The EAG 2026 Global Application & Builder Initiative is well underway🧑‍💻 As the Ethereum ecosystem enters its next phase of application innovation, EAG is expanding structured regional builder programs that connect developers, universities, founders, and local communities to a global application acceleration pathway. Here's how builders can get involved. 👇

Today we're launching EthSystems. We build confidential systems for institutional Ethereum. Institutions want to use Ethereum, but one of the biggest problems is the lack of built-in, modular privacy tools. We were the Ethereum Foundation's Institutional Privacy Task Force (IPTF) for the past year. We had hundreds of conversations with central banks, regulators, tier-one banks, and asset managers, shipping open source work the whole time. Wall Street has found crypto as an asset class, but not yet as commercial infrastructure. Institutions want to run real flows on Ethereum: stablecoins, tokenized assets, settlement. These are businesses with billions of dollars on the line, and no bank will operate in full public view. On a public ledger, confidentiality is the hard part: each party to a transaction should see what it has a right to see, and nothing more. We have a year of proof of work: private bonds, confidential stablecoin transfers, private settlement across chains, the Ethereum Privacy Map, and more. All with protocol specs and security properties, at our website. We've spent a decade working on privacy in crypto. We know there's no silver bullet. Different use cases need different systems, each designed, specified, and hardened properly, and someone has to do that work. That's why EthSystems exists. We're an independent, for-profit company, backed by long-term Ethereum-aligned investors. This is a decade-long transition, and we aren't going anywhere. If you're an institution that wants to build on Ethereum, talk to us. We're hiring: BD in New York, protocol engineers, ops: [email protected]
