Abstract

The Ripple-developed XRP Ledger (XRPL) is fundamental for securing blockchain transactions efficiently. However, the rise of quantum computing threatens the cryptographic algorithms the XRPL relies on, for example Secp256k1 and Ed25519-donna for securing transactions and validating digital signatures. Shor’s and Grover’s algorithms can break the security of Secp256k1 and Ed25519-donna which will make them vulnerable to attack. To mitigate this critical threat, we propose integrating Post-Quantum Cryptographic (PQC) algorithms into XRPL. Our focus is on the NIST standardized CRYSTALSDilithium candidate, which is a lattice-based algorithm that offers robust security against classical and quantum attacks. By incorporating CRYSTALS-Dilithium alongside existing classical algorithms, a smooth transition to quantum resistance is enabled while also ensuring backward compatibility. This requires modifications to the XRPL protocol, key management infrastructure, and transaction validation process. Our approach not only strengthens XRPL against future threats, but also sets a standard for quantum-resistant blockchain security.
