XRP Ledger contributor proposes 2027 hybrid quantum testing and 2028 mainnet upgrade

An XRP Ledger Foundation contributor suggested starting hybrid post-quantum cryptography testing in 2027 with a possible mainnet transition in 2028 to enhance quantum resistance. This proposal is not yet part of any official XRPL roadmap or amendment and requires extensive testing and validator approval before activation. The upgrade aims to protect against future quantum computer threats by introducing new signature algorithms alongside existing ones. Comparatively, Ethereum targets full quantum security by 2029, but neither timeline is guaranteed as both remain subject to development and governance processes.
