This site (120btC.coM): Blockchain currently seems difficult to crack, but there has been doubt in the market that with the advent of quantum computers, existing blockchains will be able to be cracked Cryptocurrency encryption algorithms, such as Bitcoin's SHA-256 and Ethereum's Keccak-256, quantum computers will be able to steal or forge cryptocurrencies, posing a major threat to the security of cryptocurrencies.
Recovery forks can resolve the crisis
Ethereum co-founder Vitalik Buterin wrote an article on the Ethereum Research Forum titled "How to save user funds from the threat of quantum attacks through hard forks" ”, pointing out that if Ethereum is attacked by quantum computing, the situation can be saved through a relatively simple recovery fork. This means that Ethereum will need to undergo a hard fork and users will need to update their wallet software, but the number of users losing funds will be minimized.
According to Vitalik Buterin, the solution to the recovery fork has the following steps:
Roll back all blocks after a large-scale attack
Disable traditional transactions based on Externally Owned Account (EOA) addresses
Add a new transaction type to allow transactions via smart contract wallets (such as RIP-7560 Part of the content) to conduct transactions
Introduces new transaction types or operation codes to allow users to submit proof of STARK validity. Once verified, the user address will be converted to a new verified address code, and the user can use this new address as a smart contract wallet.
Vitalik Buterin added that in order to save Gas, due to the large amount of STARK proof data, Ethereum can support batch STARK proofs to conduct multiple above-mentioned types of STARK proofs at the same time. .
Promote the rapid development of the required infrastructure
Vitalik Buterin finally called on, in principle, developers can start working on the infrastructure required to achieve this recovery fork tomorrow. Development to enable the Ethereum ecosystem to be fully prepared for sudden quantum attacks.
The above is the detailed content of Buterin: There is a solution if Ethereum is attacked by quantum computers! Restorative forks can resolve crises. For more information, please follow other related articles on the PHP Chinese website!
