Odaily Planet Daily News reports that Ripple has announced a phased roadmap, planning to push the XRP Ledger to complete a quantum-resistant upgrade by 2028. The plan includes developing a “Quantum-Day” emergency scheme to respond to sudden scenarios in which quantum computing threats emerge, and cooperating with Project Eleven to carry out preliminary testing and validation. Ripple stated that this move is intended to prepare in advance for a post-quantum security transition, and the entire plan will be advanced in four stages: First stage: Q-Day emergency preparedness (already underway). Establish a Quantum Day (Q-Day) emergency response mechanism. If the current classical cryptography system is suddenly compromised, the network will immediately stop accepting traditional public key signatures and force migration to quantum-safe accounts. Second stage: Risk assessment and algorithm testing (first half of 2026). After a comprehensive assessment, conduct evaluation and testing of the post-quantum cryptography for XR
