postquantumsignatures

Aptos has taken a significant step towards enhancing blockchain security with the proposal of AIP-137, introducing post-quantum signatures to protect against future quantum computing threats. This optional upgrade will utilize the SLH-DSA (Stateless Hash-Based Digital Signature Algorithm) scheme, standardized by NIST as FIPS 205, which relies on the secure SHA-256 hash function. The goal is to future-proof the network without disrupting existing accounts or requiring forced migration

Key Benefits

Enhanced Security*: Protects against potential quantum computer attacks
Optional Upgrade*: Existing accounts remain unaffected, with users opting in for post-quantum security
Conservative Approach*: Prioritizes security over efficiency, using proven hash functions

This proposal reflects Aptos' proactive stance on quantum resistance, positioning itself as a leader in blockchain security. Other blockchains, like Solana, are also exploring post-quantum cryptography
