Justin Drake, a researcher at the Ethereum Foundation, has called on the blockchain industry to begin planning for "bunker mode" by migrating funds to addresses with hidden public keys. In a post on X, Drake warned that artificial intelligence could break ECDSA, the signature scheme used by Bitcoin and Ethereum, before the arrival of Q-Day, the point when quantum computers become capable of cracking current encryption. He suggested that in the worst-case scenario, this breakthrough could occur "in months not years," defined as recovering a private key within about a week using available hardware such as large GPU clusters.
Drake cited rapid developments in AI-driven mathematics, including 722 results published by OpenAI, as evidence that long-held security assumptions are eroding. He argued that elliptic curves are particularly vulnerable to superintelligence due to their mathematical structure, whereas hash functions are designed to resist such attacks. While urging holders not to panic or rush, he recommended moving assets to fresh addresses where public keys remain hidden behind a hash. Drake also highlighted specific risks for wallets holding less than 50 BTC, noting they benefit from partial protection via "Satoshi's shield," which refers to approximately 20,000 exposed addresses tied to Bitcoin's creator that would likely be targeted first. He urged major entities including Binance, Bitbank, Robinhood, Bitfinex, and Tether to harden their cold storage protocols.
The shift in threat assessment from quantum computing to artificial intelligence introduces a more immediate and unpredictable risk vector for crypto infrastructure. By suggesting that ECDSA vulnerabilities could manifest in months rather than years, Drake challenges the timeline assumptions underpinning current security roadmaps. This acceleration implies that institutions relying on standard signature schemes may face operational risks sooner than anticipated, necessitating urgent reviews of custody practices and address hygiene. The emphasis on hiding public keys through migration to fresh addresses highlights a practical mitigation strategy that does not require new cryptographic standards but demands significant logistical coordination across exchanges and wallet providers.
For the broader market, this warning underscores the fragility of foundational cryptographic primitives against evolving computational techniques. The call to accelerate Ethereum’s transition to hash-based cryptography signals potential changes in network development priorities, possibly diverting resources from other upgrades to focus on defensive measures. Institutional adoption may face heightened scrutiny regarding compliance and asset protection if the perceived window for vulnerability narrows. Stakeholders must monitor whether major exchanges implement the recommended cold storage hardening and if the Ethereum Foundation successfully fast-tracks its post-quantum roadmap to maintain confidence in long-term asset security.
