Ripple XRP quantum security plan races to beat a 9-minute hacking threat by 2028

Ripple isn’t waiting for a crisis to force its hand. Engineers at the payments-focused blockchain firm are moving now to strengthen Ripple XRP quantum security years before quantum computers are expected to pose any real danger to blockchain networks, rolling out a four-stage roadmap designed to protect the XRP Ledger long before the day researchers call “Q-Day” ever arrives.

Key takeaways

• A four-stage plan has been presented by Ripple to ready the XRP Ledger against quantum computers capable of potentially revealing private keys.
• The strategy includes assessing vulnerabilities, testing quantum-resistant cryptography, running old and new security systems in parallel, and keeping an emergency response ready.
• A separate report from Crypto Briefing ties the effort to a broader roadmap targeting full quantum readiness by 2028, with testing of NIST-standard algorithms like ML-DSA and Dilithium already underway alongside Project Eleven.
• Google’s Quantum AI team estimated in March 2026 that just 500,000 physical qubits could be enough to derive a private key from an exposed public key in roughly nine minutes.
• An independent audit cited by Crypto Briefing found only 0.03% of XRP’s total supply sits in dormant accounts with exposed public keys, a much smaller exposure than Bitcoin’s older P2PK addresses.

Ripple’s Four-Stage Plan to Quantum-Proof the XRP Ledger

Ripple’s response to the quantum question is built as a long-term infrastructure project rather than a rushed patch job. “The goal is not to wait until quantum computing becomes an immediate threat,” Ayo Akinyele, Ripple’s senior director of engineering, told CoinDesk. “It is to make sure critical financial infrastructure can evolve well before that point without disrupting the systems, assets and users that depend on it.”
