[Aptos Announces Proposal AIP-137 to Introduce Quantum-Resistant Signature SLH-DSA] Aptos has announced proposal AIP-137, which aims to introduce quantum-resistant signatures to address the network's reliance on digital signatures for ownership verification, transaction authorization, and overall security. Although existing cryptographic schemes are currently secure, this proposal seeks to mitigate the potential risks posed by future quantum computers that could forge schemes and compromise account security. If approved through governance review, Aptos will introduce SLH-DSA, standardized as FIPS 205, as an optional account signature type, making it one of the first blockchains to natively support quantum-resistant accounts, with existing accounts remaining unaffected.
