Ripple Releases Four-Phase Plan to Make XRP Ledger Quantum-Proof by 2028
TLDR
- Ripple has announced a four-phase roadmap to make the XRP Ledger quantum-proof by 2028
- Google research found just 500,000 qubits could break elliptic curve cryptography in about nine minutes
- Phase 2 is already underway, testing NIST-standard post-quantum algorithms ML-DSA and Dilithium
- Only 0.03% of XRP supply sits in dormant accounts with exposed public keys, less than Bitcoin’s exposure
- Bitcoin and Ethereum are also working on quantum-resistant cryptography upgrades
Ripple has published a four-phase plan to protect the XRP Ledger from future quantum computing attacks. The roadmap, announced on April 20, 2026, sets a target of full quantum readiness by 2028.

The plan comes after Google’s Quantum AI team found in March 2026 that just 500,000 physical qubits could break elliptic curve cryptography, the system that keeps private keys secure across most blockchains. At that level, a quantum computer could crack a private key from a public key in roughly nine minutes.
