Odaily Planet Daily reports: On November 4, the XRP Ledger Foundation updated its 2027 Protocol Roadmap to introduce a quantum-resistant account design, allowing account owners to add quantum-resistant signing keys and disable their original keys to defend against future quantum computer attacks. Since account signatures expose public keys on-chain, all accounts that have ever sent payments—including exchange wallets—are already exposed. The new keys employ the ML-DSA-44 signing scheme approved by the U.S. National Institute of Standards and Technology (NIST) in 2024, with combined key and signature sizes of 3,732 bytes, adding approximately 3.6 KB per protected transaction. Users incur no additional fees; base transaction fees remain unchanged, and the extra storage costs are borne by network operators.

Summary
On November 4, the XRP Ledger Foundation unveiled a quantum-resistant account design as part of its 2027 protocol update. The update enables users to add ML-DSA-44 signature keys and disable older ones, with each transaction adding approximately 3.6KB of data. No additional fees are charged, as operators absorb the costs. The protocol update is designed to future-proof the network against quantum computing threats, and new token listings may also benefit from this enhanced security framework.
