Ripple has established a four-phase quantum-resistant migration plan for the XRP Ledger

Ayo Akinyele, Senior Director of Engineering at Ripple, stated that the company is developing a four-phase quantum-resistant migration plan for the XRP Ledger, aiming to complete the transition before quantum computers become a real threat. The plan includes assessing the network's exposure, testing quantum-resistant cryptographic solutions, running existing security systems in parallel with quantum-resistant alternatives, and preparing emergency response pathways for scenarios where quantum computing advances exceed expectations.

Akinyele emphasized that migration is not just about replacing a cryptographic algorithm, but requires more flexible infrastructure, stronger key management, and clearer upgrade paths. The XRP Ledger has supported changing the keys that control accounts without altering the accounts themselves, a feature that is expected to reduce the difficulty of future migrations, but independent validators on the network still need to coordinate any broader rule changes.

Meanwhile, Anthropic's model last month reduced the workload required to break leading post-quantum signature candidates by 67 million times, and Bitcoin and Ethereum developers also released their respective migration plans this week. Akinyele pointed out that AI and quantum computing are different technologies, but they are driving financial infrastructure to evolve in the same direction, as AI agents begin to trade and pay autonomously, raising new requirements for payment infrastructure that is always online and natively internet-based.
