Ripple Aims to Make XRP Ledger Quantum-Resistant by 2028 with a 4-Phase Plan

The emergence of quantum computing poses a significant threat to blockchain security, prompting Ripple to develop a detailed plan to make the XRP Ledger quantum-resistant by 2028. As a decentralized, layer-1 blockchain, the XRP Ledger is the foundation for the world's fourth-largest digital asset, XRP, and is integral to Ripple's solutions. With Google's recent warning that a quantum computer could potentially compromise Bitcoin with less computational power than previously thought, the urgency to develop defenses has increased. Ripple's plan is designed to mitigate the risks associated with quantum computing, which include the potential for a quantum computer to reverse-engineer private keys from exposed public keys, thereby draining coin holdings. The plan consists of four phases, starting with an emergency measure called Q-Day readiness, which would protect exposed public keys and long-held accounts in the event of an unexpected quantum breakthrough. The subsequent phases involve assessing quantum vulnerability, integrating post-quantum measures, and ultimately transitioning the network to quantum-resistant signatures. By 2028, Ripple aims to have completed the transition, ensuring the XRP Ledger's security and integrity in a post-quantum world.
