XRP Ledger Plans Quantum-Resistant Accounts
The XRP Ledger Foundation has outlined a plan to make user accounts more resistant to potential quantum-computing attacks. The proposed design would let account owners add a new quantum-resistant signing key and then disable the old one. This matters because public keys can be exposed when accounts sign transactions, potentially creating a future security risk if sufficiently powerful quantum computers become available. The proposed approach uses ML-DSA-44, a signature standard approved by the US National Institute of Standards and Technology. Developers aim to keep the network’s base transaction fee unchanged despite the additional data required for protected transactions. The upgrade is not ready yet: technical work, testing and audits remain ahead, with a full transition targeted for 2028. Track XRP rates and compare exchange terms on xbit.money.
