Ripple Plans Four-Stage Quantum-Resistant Migration for XRP Ledger

Ripple Senior Director of Engineering Ayo Akinyele said the company is developing a four-stage quantum-resistant migration plan for the XRP Ledger, aiming to complete the transition before quantum computers become a practical threat. According to ChainCatcher, the plan includes assessing network exposure, testing quantum-resistant cryptographic schemes, running current security systems alongside quantum-resistant alternatives, and preparing contingency responses if quantum computing advances faster than expected. Akinyele said the migration involves more than replacing one encryption algorithm and will require more flexible infrastructure, stronger key management, and clearer upgrade paths. He added that the XRP Ledger already allows the key controlling an account to be changed without altering the account itself, which could reduce future migration difficulty, although independent validators would still need to coordinate any broader rule changes. Akinyele also noted that Anthropic's model last month reduced the work needed to break a leading post-quantum signature candidate by 67 million times, while Bitcoin and Ethereum developers also released their own migration plans this week. He said AI and quantum computing are different technologies but are pushing financial infrastructure in the same direction, as AI agents begin trading and making payments autonomously and create demand for always-on, internet-native payment systems.
