Ripple and the XRP Ledger Foundation have partnered with post-quantum cryptography firm Project Eleven to prepare the XRP Ledger (XRPL) for future threats posed by quantum computing.
The collaboration aims to transition the network’s security from theoretical research into active engineering, with the goal of implementing quantum-resistant cryptography across the XRPL before quantum computers become powerful enough to break current encryption standards.
Currently, the cryptographic frameworks underlying major blockchain networks, including Bitcoin, Ethereum, Solana, and XRP, are vulnerable to future quantum attacks. While the exact timeline for “Q Day” (the point at which quantum computers break standard encryption) remains uncertain, the U.S. government has mandated a 2035 deadline for federal systems to migrate to post-quantum security, with tech giants like Google targeting 2029.
To address the vulnerability on the XRPL, Project Eleven will first conduct a comprehensive audit of the network’s validator, custody, networking, and wallet layers. Following the assessment, the firm plans to deploy a prototype for a quantum-secure custody wallet and implement “hybrid signatures,” which layer quantum-resistant cryptography directly over the network’s existing security standards.
Migration process
The XRP Ledger Foundation noted that the network’s native architecture simplifies the migration process. Because the XRPL utilizes an account-based system with built-in key rotation, network participants, including businesses and individual users, will be able to upgrade to quantum-resistant signatures without needing to change their existing, public “r-addresses.”
Alex Pruden, CEO of Project Eleven, noted that while every major blockchain faces the same cryptographic exposure, the industry’s response has largely remained in the research phase. The engagement with Ripple is focused heavily on execution and delivering working code.
