The new proposal from Aptos suggests introducing quantum-resistant signatures as an optional account signature type

According to Cointelegraph, on Thursday, Aptos announced a proposal to introduce quantum-resistant signatures, AIP-137, aimed at addressing the network's reliance on digital signatures for ownership confirmation, 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 compromising 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 earliest blockchains to natively support quantum-resistant accounts. However, existing accounts will remain unaffected, and quantum-resistant accounts will be available for users to choose. Previously, it was reported that Solana would collaborate with Project Eleven to build quantum-resistant signatures.
