Ripple's Plan to Make XRP Ledger Quantum-Resistant by 2028

The emergence of quantum computing poses a potential threat to blockchain technology, prompting fintech company Ripple to develop a comprehensive plan to make the XRP Ledger quantum-resistant. As the native token of the XRP Ledger, XRP is the fourth-largest digital asset by market capitalization, and Ripple's solutions rely on the XRP Ledger, XRP, and other digital assets. In response to Google's warning that a quantum computer could potentially attack Bitcoin with less computational power than previously estimated, Ripple has released a detailed roadmap to achieve full quantum resistance by 2028. The plan consists of four phases, starting with an emergency measure called Q-Day readiness, which aims to protect exposed public keys and long-held accounts in the event of an unexpected quantum attack. This initial phase involves implementing a hard shift, where classical public-key signatures will no longer be accepted by the network, and all funds will need to migrate to quantum-safe accounts. The subsequent phases involve assessing quantum vulnerability, testing defenses, integrating post-quantum measures, and ultimately transitioning the network to quantum-resistant signatures. By 2028, Ripple aims to complete the full transition to post-quantum cryptography, ensuring the XRP Ledger's security and stability in the face of emerging quantum threats.
