Ripple's Roadmap to Make XRP Quantum-Resistant by 2028
Ripple published a four-phase roadmap to make the XRP Ledger quantum-resistant by 2028, with hybrid post-quantum cryptography testing starting in H1 2026 and a "Quantum-Day" emergency protocol included for accelerated migration if threats materialize before that target. The roadmap responds to Google Quantum AI research showing approximately 500,000 physical qubits could derive a private key from an exposed public key in about 9 minutes, a 20-fold improvement over prior estimates, a threat level that puts roughly 6.9M BTC with exposed public keys at theoretical risk. XRPL's native key rotation gives users the ability to migrate accounts without abandoning them, a structural advantage over Ethereum, where post-quantum migration requires manual asset transfer.
