The XRP Ledger Foundation has released a protocol roadmap that includes quantum-resistant signature schemes in its proposed 2027 amendments, which will introduce the ML-DSA-44 signature algorithm to support account migration to quantum-resistant keys.
The proposal is currently in the proposal stage, with migration studies planned for the first half of 2027, followed by development, review, and auditing by the end of 2027 or 2028. The new key and signature will be larger than the existing proposal, and the final implementation of the amendment will require validator voting.
