Ripple announced a multi-phase roadmap Monday to make the XRP Ledger quantum-resistant by 2028, responding to recent Google research demonstrating that future quantum computers may break current blockchain cryptography by 2032.

The company will begin active testing of quantum-resistant cryptography and a hybrid rollout that runs alongside existing systems in the first half of 2026, according to the roadmap. Ripple is collaborating with Project Eleven, an organization working on validator testing and early custody prototypes for post-quantum cryptography, to speed up development.

The roadmap includes a “Quantum-Day” contingency plan to enable secure migration to quantum-safe accounts if current cryptographic standards are…
