XRP Ledger quantum target awaits formal roadmap

An XRP Ledger contributor has proposed hybrid post-quantum testing in 2027 and a mainnet transition in 2028, although no published XRPL roadmap has confirmed either deadline. Summary An XRPL Foundation contributor has proposed 2027 hybrid testing and a 2028 mainnet transition target. No official XRPL roadmap currently confirms the contributor’s proposed 2028 quantum-readiness deadline for mainnet deployment. XRPL currently supports secp256k1 and Ed25519 signatures, both exposed to sufficiently capable quantum computers someday. Existing RegularKey functionality allows XRPL accounts to change signing keys while retaining their public addresses. Ethereum researcher Justin Drake expects Ethereum’s three cryptographic layers to become post-quantum secure by 2029. Vet, an XRP Ledger Foundation contributor and validator on the decentralized Unique Node List, presented the dates in a Sept. 9 post on X. The contributor described an expected testing phase followed by a hybrid system in which conventional and quantum-resistant signatures would operate together. Quantum secure accounts is just one part, Algorand is not fully quantum ready either. Lots of Ed25519 use on the network. That's why...
