Ripple announced a four-phase roadmap to prepare the XRP Ledger for post-quantum security risks, targeting full readiness by 2028. According to Ripple, the plan is intended to address the longer-term threat that advances in quantum computing could eventually break current blockchain cryptography, a concern it linked to recent Google Quantum AI research. The roadmap includes Q-Day recovery preparation, testing in 2026 with Project Eleven using NIST-recommended algorithms, Devnet integration in late 2026, and a 2028 amendment to add native post-quantum cryptography to the network.
