Users don't need to pay extra fees: XRP Ledger proposes a quantum-resistant account solution

Odaily reports that the XRP Ledger Foundation, in its 2027 protocol roadmap updated on November 4, proposed a quantum-resistant account design that allows account owners to add quantum-resistant signing keys to their accounts and disable the original keys to guard against future quantum computer attacks. Because account-signed transactions expose public keys on-chain, all accounts that have ever sent payments (including exchange wallets) have already exposed their public keys. The new keys use the ML-DSA-44 signature scheme approved by the U.S. National Institute of Standards and Technology (NIST) in 2024, with keys and signatures totaling 3,732 bytes, adding approximately 3.6KB to each protected transaction. Users do not need to pay extra fees, the base fee remains unchanged, and the additional storage costs are borne by network operators.
