XRP Ledger Foundation Roadmap Proposes Quantum-Resistant Signature Scheme

November 10 - According to the protocol roadmap published by the XRP Ledger Foundation, the foundation has included quantum-resistant signature schemes in its proposed amendments for 2027, planning to introduce the ML-DSA-44 signature algorithm to enable accounts to migrate to quantum-resistant keys.

The proposal is still in the proposal stage, with plans to conduct migration research in the first half of 2027, and development, review, and auditing by the end of 2027 or in 2028. The size of the new keys and signatures is far larger than existing schemes, and the final activation of the amendment still requires validator voting.
