Justin Drake, a researcher at the Ethereum Foundation, recently suggested that AI could potentially compromise the ECDSA digital signature algorithm sooner than quantum computers. He proposed a 'bunker mode' strategy, advising users to move assets to addresses where public keys have not yet been exposed on the blockchain.
The proposal faced significant backlash from industry experts. Haseeb Qureshi of Dragonfly labeled the idea 'cryptographic doomerism,' arguing that moving funds does not provide long-term security. Other critics, including Coinbase’s Yehuda Lindell and MetaMask’s Taylor Monahan, noted that there is no evidence of a mathematical breakthrough that would render ECDSA vulnerable to AI.
Experts also pointed out technical flaws in the bunker strategy. Foundation CEO Zach Herbert explained that extended public keys (xpub) often already expose future addresses to third-party applications. Furthermore, StarkWare CEO Eli Ben-Sasson noted that a signature compromise would require a massive infrastructure overhaul, as it would affect consensus mechanisms and data structures like KZG commitments.
Critics like Trezor analyst Lucien Bourdon suggested that Drake’s warning might be a marketing tactic for Ethereum’s own roadmap toward hash-based cryptography. Meanwhile, Solana Foundation’s Jacob Creech stated that Solana is already resilient to such threats due to its use of Ed25519 and a seed-based derivation model, making a 'bunker mode' unnecessary for their users.
While no practical attack has been demonstrated, some experts acknowledge the long-term need for quantum-resistant signatures. Bitwise Europe’s Max Shannon noted that while the risk is theoretical, caution is warranted. Ethereum has previously explored an emergency hard-fork scenario involving zero-knowledge proofs to recover funds if mass theft occurs.
