🔐 XRP Ledger plans quantum-resistant accounts, with no extra fees for users
A quantum research report from the XRP Ledger Foundation proposes a design that lets account holders add a quantum-resistant signing key and disable their existing key to protect against attacks by future quantum computers. The proposal is part of the Foundation’s 2027 protocol roadmap, updated on November 4. The new key uses the ML-DSA-44 algorithm, approved by the U.S. National Institute of Standards and Technology (NIST) in 2024.
The key and signature together are about 3,732 bytes—far larger than the 105 bytes used for a typical payment today. However, the proposal keeps the base fee unchanged, with network operators absorbing the additional storage costs. Development is ongoing, including a fix for an issue where different implementations could generate different keys from the same seed. Ripple aims to complete a full quantum migration by 2028, while the Foundation plans to conduct migration research in the first half of 2027.
⭐ Any account that has sent a transaction and thereby exposed its public key faces a potential quantum threat. This proposal aims to enable migration without increasing user fees.
