Ripple Releases Post-Quantum Roadmap for XRPL, Aiming for Full Transition by 2028

On April 21, Ripple announced a multi-phase post-quantum roadmap for the XRP Ledger (XRPL), aimed at equipping it to handle future quantum threats, with a plan for full readiness by 2028. The roadmap is divided into four phases: the first phase focuses on post-quantum recovery (Q-Day preparation), emphasizing the development of contingency plans to ensure safe migration of funds when classical cryptographic standards are compromised; the second phase, scheduled for the first half of 2026, will involve proactive planning and experimentation to assess quantum risks and collaborate with Project Eleven to test NIST-recommended algorithms; the third phase is expected to take place in the second half of 2026, integrating post-quantum signature schemes into Devnet and exploring privacy primitives; the fourth phase aims for 2028, proposing new amendments to the ecosystem for a comprehensive transition to native post-quantum encryption. Ripple stated that the existing key rotation and seed-based key generation features of XRPL lay the groundwork for this migration, providing a native protocol advantage in addressing quantum threats compared to networks like Ethereum.
