Ethereum Co-Founder Vitalik Buterin Suggests Recovery Fork to Counter Quantum Attacks

According to BlockBeats, on March 10th, Ethereum co-founder Vitalik Buterin proposed a 'recovery fork' as a solution to potential quantum attacks in an Ethereum research forum. Buterin stated that although quantum computing attacks could pose a threat, Ethereum is prepared to protect users' funds through a simple 'recovery fork'. This backup plan can be implemented in the event of a blockchain hard fork, where users would need to download a new wallet, but relatively fewer users would lose their funds. The proposed recovery fork would involve: 1. Rolling back all blocks after the first block of a large-scale attack; 2. Disabling traditional EOA (Externally Owned Account) transactions; 3. Adding new transaction types that allow transactions from smart contract wallets; 4. Adding new transaction types or opcodes that allow for STARK proofs. If the proof is successful, the user's account code will switch to a new verification code, and from then on, it can be used as a smart contract wallet. To improve gas efficiency, STARK proofs can be batched, proving N STARKs of the above type (must be STARK-of-STARKs, not directly proving multiple statements). In principle, the infrastructure for implementing this hard fork can be built from now on, allowing the Ethereum ecosystem to be fully prepared for a potential quantum emergency.
