The famous threat is the quantum computer: someday, the theory goes, a big enough machine slices through the elliptic-curve signatures — ECDSA — that Bitcoin and Ethereum use to prove a transaction was authorized by the rightful owner. On Wednesday, Justin Drake, a researcher at the Ethereum Foundation who has spent years warning about exactly that scenario, said something more alarming, as [Decrypt reported](https://decrypt.co/380363/ethereum-researcher-ai-break-encryption-before-quantum): artificial intelligence might get there first, in the worst case “in months not years.” > 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. Here is why the fresh-address distinction is the whole ballgame. Each wallet has a secret private key and a public key derived from it. The public key sits behind a scrambled version of itself — a hash — until the first time money leaves the wallet. The moment you send a transaction, your public key goes onto the blockchain, permanently. If anyone ever figures out how to run ECDSA backward — to take a public key and compute the private key behind it — then every wallet that has ever spent anything is an open safe, and every wallet that has only ever received is not. So the Drake plan reduces to: everyone quietly move their coins to wallets that have only ever received money, before the safe-cracking begins. Drake’s definition of “break” is concrete enough to be unsettling: recovering a private key in about a week on available hardware, something like a large cluster of graphics cards. He says it is now reasonable to prepare for that happening before Q-Day, the moment quantum computers grow strong enough to crack today’s encryption. What changed his mind is velocity. On Tuesday, OpenAI published 722 mathematical results, which Drake took as a sign that long-held assumptions about hard problems are falling fast. Elliptic curves, he argued, are exactly the sort of object a superintelligent system might find tractable. “Elliptic curves feel especially vulnerable to superintelligence,” he wrote — they have rich mathematical structure, meaning lots of patterns for a very clever attacker to exploit, while the hash functions hiding your public key are purpose-built to resist that kind of cleverness. The rough worry is that your coins are protected by math that looks like a riddle, and AI has lately become very good at riddles. There is even a crude early-warning system, which Drake calls Satoshi’s shield. Roughly 20,000 exposed addresses tied to Bitcoin’s creator each hold 50 BTC — a million bitcoins in total, all in wallets whose public keys are already visible and which any successful codebreaker would presumably loot first. Small holders, in other words, get partial cover from the fact that the biggest pile of vulnerable money in the world belongs to a pseudonymous ghost. As a bonus, the alarm is automatic: you will know ECDSA has fallen the day Satoshi’s coins move. Context for the stakes, from Tyler Warner’s [*Morning Minute* newsletter at Decrypt](https://decrypt.co/380402/morning-minute-ethereum-researcher-says-ai-may-break-crypto-encryption-before-quantum): bitcoin was trading around $82,600 on Wednesday after another 2 to 3 percent slide across the majors, putting the shield’s value at roughly $82.6 billion. This is a marked escalation even by the standards of crypto doom. Back in March, after a Google paper suggested quantum machines could break crypto’s cryptography sooner than expected, Drake put the odds of Q-Day arriving by 2032 at 10 percent or more. The Ethereum Foundation formed a dedicated post-quantum team earlier this year, and co-founder Vitalik Buterin has laid out plans to migrate the network toward quantum-resistant cryptography. Drake now says Ethereum’s shift to hash-based cryptography should be accelerated hard. “I’ll be pushing for maximum defensive acceleration,” he wrote. And he is no longer alone at the office. Europol published two reports on Wednesday concluding that crypto wallets are the main weak point in future attacks, Warner’s newsletter notes — and, critically, that wallets which have already revealed their public keys cannot be patched after the fact. Those funds have to move before any attack exists. Europol does not expect crypto to collapse. It does think the clock runs per wallet. So what does one calmly do in bunker mode? Drake is careful to say don’t panic and don’t rush, and that moving to a fresh address requires no new cryptography or new wallets. He called out Binance, Bitbank, Robinhood, Bitfinex and Tether by name, urging them to harden their cold storage. For the less hardcore, the newsletter floats the ordinary-finance alternatives: use the bitcoin ETFs, use a proven custodian like Coinbase, or, if you insist on holding your own keys, work with experts to make sure you’re doing it right. Any action, the thinking goes, beats hoping it all blows over. I think the interesting assumption is the one about human beings. The plan asks millions of holders to perform a controlled mass migration of assets, in orderly fashion, possibly over months, without a stampede, a phishing bonanza or anyone’s uncle sending his savings to a fake “bunker mode helper” on Telegram. Sure. The comforting part, if you squint, is that the plan ships with its own siren. If you wake up one morning and a million of Satoshi’s bitcoins have moved, you’ll know bunker mode is over — and which side won. ## Sources - [AI Could Break Crypto Encryption Before Quantum, Says Ethereum Researcher](https://decrypt.co/380402/morning-minute-ethereum-researcher-says-ai-may-break-crypto-encryption-before-quantum) — decrypt.co - [Ethereum Researcher Says AI May Break Encryption Before Quantum Does](https://decrypt.co/380363/ethereum-researcher-ai-break-encryption-before-quantum) — decrypt.co
