The plan includes an emergency phase for migrating to quantum-safe accounts and enabling fund recovery through zero-knowledge proofs. Subsequent phases will evaluate XRPL's vulnerabilities, test post-quantum cryptography, and implement quantum-resistant signatures while ensuring minimal disruption for existing users."

# Ripple wants the XRP Ledger to be quantum-proof by 2028. Here is its plan

-   Ripple has unveiled a four-phase plan to make the XRP Ledger quantum-resistant by 2028, positioning it for a potential "Q-day" when quantum computers can break current cryptography.
-   The roadmap includes an emergency "Q-day readiness" phase that would force a migration to quantum-safe accounts and enable fund recovery via zero-knowledge proofs if quantum threats arrive sooner than expected.
-   Subsequent phases through 2026 and beyond will assess XRPL's quantum vulnerabilities, test and integrate post-quantum cryptography at scale, and ultimately amend the network to use quantum-resistant signatures without disrupting existing users.
