ME News - News, December 19 (UTC+8), Thursday, Aptos announced a proposal introducing quantum-resistant signatures, AIP-137, aimed at addressing the network's reliance on digital signatures for ownership verification, transaction authorization, and overall security. Although existing cryptographic schemes remain secure against traditional computers, researchers warn that one day, sufficiently powerful quantum computers may be able to forge these schemes, potentially retroactively undermining account security. If the proposal passes governance review, AIP-137 will introduce SLH-DSA (a hash-based digital signature scheme standardized as FIPS 205) as an optional account signature type. This will make Aptos one of the first blockchains to natively support quantum-resistant accounts. However, existing accounts will remain unaffected, and quantum-resistant accounts will be available for user adoption. Previously, it was reported that Solana will collaborate with Project Eleven to build quantum-resistant signatures. (Source: ME)
