According to the Daily Planet, Ethereum co-founder Vitalik Buterin published a short article on the Ethereum Research Forum to discuss how to deal with sudden quantum attacks through hard forks. Vitalik mentioned that if a quantum attack comes sooner than expected, Ethereum can solve the problem through a "restorative fork." Fork-related changes include: rolling back all blocks after a large-scale attack; disabling the traditional transaction mode based on EOA addresses; adding new transaction types to allow transactions through smart contract wallets; adding new transaction types or operation codes, users can provide STARK Proof, switch to the new verified code after passing the proof; support batch STARK proof, saving Gas.
