Ripple wants the XRP Ledger to be quantum-proof by 2028. Here is its plan* đâď¸
Quantum computers aren't breaking crypto today. But Ripple isn't waiting for âQ-Dayâ to find out.
They just laid out a 4-phase roadmap to make the XRP Ledger fully quantum-resistant by 2028 â a full year before Googleâs 2029 post-quantum target.
*The 4-phase plan:*
*1. Quantum-Day Contingency*
If classical crypto breaks unexpectedly, XRPL would block old signatures and let users prove ownership via post-quantum zero-knowledge proofs. Think âemergency migration modeâ.
*2. Algorithm Testing â H1 2026*
Ripple + Project Eleven are benchmarking NIST-approved algorithms like ML-DSA. Theyâve already tested ML-DSA on XRPLâs AlphaNet.
*3. Hybrid Mode â H2 2026*
Post-quantum signatures run alongside ECDSA on Devnet. Devs can test performance, wallet impact, and throughput before mainnet.
*4. Full Production â by 2028*
Formal amendment for native post-quantum crypto. Goal: network-wide upgrade without killing XRPLâs 3-5 sec finality.
*Why XRPL has an edge:*
Unlike BTC or ETH, XRPL supports native key rotation. You can swap to a quantum-safe key without moving funds or making a new account.
*The challenge:*
PQ signatures are bigger. More bandwidth, more storage. Rippleâs spending 2026-2027 proving the ledger can handle it at scale.
Rippleâs stance: No risk today. But âharvest now, decrypt laterâ attacks mean the time to prep is now.
*Bottom line*: Blockchains that wait until quantum is real will be too late to migrate safely. Rippleâs trying to solve it before itâs a crisis.
