Ripple sets 2028 deadline to harden XRPL after Google’s quantum research sharpens attack risk
Ripple aims to secure the XRP Ledger against quantum threats by 2028 following research by Google Quantum AI.Summary
Ripple has announced a multi-stage roadmap to transition the XRP Ledger (XRPL) to post-quantum cryptography by 2028. This initiative is driven by recent research from Google Quantum AI, which suggests that a quantum computer with approximately 500,000 physical qubits could potentially crack current ECDLP-256 cryptography, significantly narrowing the timeline for potential attacks.
The transition will occur in four distinct stages: immediate contingency planning for "Q-Day," research and performance testing in early 2026, controlled hybrid testing on Devnet in late 2026, and finally, a full production transition. A key challenge involves managing the larger size of post-quantum signatures, which could impact network speed, storage, and bandwidth.
Ripple noted that the XRPL's existing architecture, particularly its native key rotation capabilities, may simplify the migration process compared to other blockchains. The company is collaborating with Project Eleven to conduct validator-level experiments and benchmark performance to ensure a smooth transition for users and financial infrastructure.
