"All vulnerable to quantum computers?"...XRP Ledger poised to preempt 'post-quantum security' that is unhackable

The XRP Ledger (XRPL) has embarked on building a security system to prepare for the era of quantum computers. Ripple and Project Eleven are collaborating to enhance the post-quantum security readiness across the entire XRP Ledger ecosystem.

According to The Crypto Basic on May 20 (local time), the XRP Ledger Foundation stated that the XRP Ledger is already structurally prepared for the quantum computer era. The foundation highlighted built-in key rotation and account-based architecture as important strengths in the transition to quantum-resistant cryptography.

The foundation explained in an X (formerly Twitter) post that XRP Ledger users and businesses can migrate to quantum-resistant signatures while retaining their existing XRP wallet addresses. Project Eleven is conducting an audit of the XRP Ledger's network, wallets, and validator infrastructure in preparation for the full deployment of quantum security.

Project Eleven described this collaboration as one of the industry's first major instances to move post-quantum blockchain security from the theoretical stage to actual implementation. The company stated that the cryptographic technologies protecting major blockchains such as Bitcoin (BTC), Ethereum (ETH), XRP, and Solana (SOL) could become vulnerable in the face of sufficiently advanced quantum computers.

Alex Pruden, CEO of Project Eleven, pointed out that discussions about quantum risks in the blockchain industry have mostly remained at the research stage. He praised Ripple for approaching this issue as a practical engineering challenge.

J. Ayo Akinyele, Head of Engineering at RippleX, said that the XRP Ledger ecosystem is not starting from scratch. He stated that the XRP Ledger already supports features like key rotation and coordinated validator upgrades, and the goal is to be ready in a production environment long before quantum threats become critical.

This collaboration includes a comprehensive review of quantum vulnerabilities across XRP Ledger validators, custody systems, wallets, and networking layers. Both parties are also pursuing the development of a hybrid signature system that combines existing cryptographic standards with quantum-resistant protection, and the construction of a prototype quantum-secure custody wallet. Project Eleven plans to provide actual working code, performance tests, and a production deployment roadmap through this collaboration.
