T R U S T W A R E We’ve had hardware, we’ve had software, and now as more of our lives depend on digital things, we need trustware. Ethereum’s cryptographic world computer is trustware.

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.

Hot take: Trump coin, World Liberty, USD1, and Melania coin are why CLARITY failed. An unprecedented $1.3 billion pocketed. More than all past U.S. presidents made during their terms combined.

CEASE AND DECIST in all caps was my attempt at humor. It was a cross between Desist (which means to stop) and De-cyst (which would mean to remove a cyst, something that causes pain and discomfort). What you know about U.S. securities laws apparently is that you are happy to ignore them if you simply disclose that you are ignoring them. If your offshore Stock Tokens can not be offered or sold to U.S. persons, why are you touting them on your U.S. web site? If it is not illegal, it should be. And in any case, it displays a terrible lapse of judgement on your part. Wisdom is displayed not just by obeying the strict letter of the law, but by doing what is right. Shame on you.

we will finally kill "stack too deep" the next @ethereum update brings both: 1) the ability to deploy larger contracts 2) lets compilers fix "stack too deep" eth dev is going to rip in Q4

TODAY 🚨: The Commission issued an interpretation that clarifies the application of federal securities laws to crypto assets. This is a major step to provide greater clarity regarding the Commission’s treatment of crypto assets. Read the release here: ow.ly/XhhV50YvxvO

Telcoin Digital Asset Bank is granted final approval by the Nebraska Department of Banking and Finance. A historic moment for blockchain innovation, this charter enables Telcoin to bring regulated stablecoins into traditional banking. businesswire.com/news/home/2…

IDK you couldnt set a dollar amount on opensea so i just kept adding 0s til the number seemed too big for anyone to buy even as a joke

stop gambling with perps start buying spot thank you for your attention to this matter

many such cases
