AI 數學突破令 Ethereum 研究者討論錢包簽名安全可能多快失守
AI math breakthroughs have Ethereum researchers debating how fast wallet security could collapse
兩名 Ethereum 研究者警告，AI 輔助數學在最壞情況下可能於數月內破解加密錢包使用的簽名系統。Justin Drake 呼籲區塊鏈業界準備「bunker mode」，把資金轉至從未簽署交易的地址；簽署會公開公鑰，而只公開公鑰雜湊時，資金仍受保護。Vitalik Buterin 認同風險但提醒不要倉促遷移，並主張長遠盡量採用只依賴雜湊函數的架構；目前尚無人實際破解現行 ECDSA 簽名方案。
Two leading Ethereum researchers warn that AI-assisted math could, in the worst case, break the signature system used by crypto wallets within months. Justin Drake called on the blockchain industry in a post on X to prepare a "bunker mode."
He recommends moving funds to addresses that have never signed a transaction. Signing reveals the public key, which an attacker could theoretically use to derive the private key and steal the funds. As long as only the public key's hash is visible, the funds remain protected because the key cannot be recovered from that hash.
Ethereum co-founder Vitalik Buterin agreed in a reply on X but warned against acting too fast. He said he's lost more money to botched migrations than to hacks. Long-term, Buterin argues for an architecture that relies as much as possible on hash functions alone, since even lattice-based schemes, often considered quantum-safe, could be weakened by advances in AI.
So far, no one has actually broken the current ECDSA signature scheme in practice.
