XRPL Tackles Quantum Security with Broader Approach

Ripple's XRP Ledger (XRPL) is making significant strides in quantum security, according to experts. Vet, an XRPL validator, pushed back on claims that Algorand is already fully quantum-ready, noting that quantum-secure accounts are only one layer of the problem.

Algorand has made real progress, but its consensus system still relies partly on cryptography that a sufficiently powerful quantum computer could eventually threaten. Ripple, meanwhile, is working with Project Eleven on a broader system-wide XRPL assessment, including validators, custody, wallets and networking.

XRPL's roadmap targets full post-quantum readiness by 2028, which includes testing hybrid post-quantum signing, validator performance, Devnet workloads and a quantum-secure custody prototype. The plan goes beyond wallet signatures, with a focus on larger signatures, storage overhead, and throughput.

Ripple also has one structural advantage: native key rotation, allowing users to change signing keys without moving to a new account. This could make a future migration easier than on networks where assets must be manually transferred.
