XRP Ledger’s Quantum-Safe Account Plan Targets Stronger Security Without a Fee Penalty

The XRP Ledger’s path toward quantum-resistant security is becoming more concrete, and the design goal is bigger than simply swapping one cryptographic algorithm for another.

Developers are working toward an account model that can support post-quantum signatures without imposing an extra fee category on users. The proposal centers on ML-DSA-44, a standardized signature scheme designed to withstand the kind of attacks that a sufficiently powerful quantum computer could eventually make possible.

The XRP Ledger Foundation’s protocol roadmap describes the work as a draft post-quantum signature system that would let accounts move away from today’s elliptic-curve signatures before the threat becomes urgent. The roadmap also makes clear that the change is technically heavy: post-quantum keys and signatures
