XRP Ledger Plans Quantum-Safe Accounts Without Fee Increases
The XRP Ledger Foundation has detailed plans to let users protect accounts with quantum-resistant cryptography while keeping transaction fees at current levels. Account holders would add a new signing key based on the ML-DSA-44 standard approved by NIST in 2024, then turn off their existing key to block future attacks from quantum computers. The change addresses a known vulnerability where on-chain signatures expose public keys that powerful quantum machines could exploit.
