Ripple and Project Eleven Launch Quantum-Proof Security Push for XRP Ledger
Quantum computing was once viewed as a distant risk to blockchain security, but that timeline is closing fast.
In response, Ripple is working with Project Eleven to strengthen the XRP Ledger against emerging quantum-era threats.
Project Eleven, a leading post-quantum cryptography firm, has announced a partnership aimed at strengthening blockchain systems for the era of advanced computing. The collaboration centers on boosting post-quantum readiness across the XRP Ledger (XRPL), one of the longest-running public blockchains in operation.
Realistically, the quantum threat is no longer theoretical. The cryptography protecting major blockchains like Bitcoin, Ethereum, Solana, and XRP could one day be compromised by powerful quantum computers, prompting early action from governments and tech leaders.
As a result, the U.S. has already set 2035 as a deadline to retire vulnerable encryption, while firms like Google and Cloudflare are pushing to transition even sooner.
Ripple and Project Eleven Launch Quantum-Security Push to Future-Proof XRPL Before “Q Day”
Rather than waiting for quantum threats to become immediate, Ripple and Project Eleven are taking a proactive stance.
The initiative will kick off with a comprehensive audit of XRPL’s validator infrastructure, custody systems, networking layers, and wallets to uncover potential quantum vulnerabilities.
From there, the teams will roll out hybrid signature schemes that blend today’s cryptographic standards with quantum-resistant safeguards, alongside a prototype of a quantum-secure custody wallet built for real-world use.
Crucially, this goes beyond theory. Project Eleven emphasizes that the collaboration will produce working implementations, performance benchmarks, and a clear, production-ready roadmap for integrating post-quantum security across the XRP Ledger ecosystem.
According to J. Ayo Akinyele, Head of Engineering at RippleX, quantum threats can no longer be treated as distant theory. He emphasized:
"What puts XRPL in a strong position is that we are not starting from scratch. We already have core capabilities like key rotation and a validator network that can coordinate upgrades at scale. Working with Project Eleven helps us move faster and more rigorously as we test and implement post-quantum approaches across the stack. The goal is to be production ready well before we need to be, not reacting when Q Day arrives."
This undertaking highlights XRPL’s increasingly proactive security posture. A recent quantum risk review reportedly confirmed that nearly 300,000 XRPL accounts holding about 2.4 billion XRP remain secure, with only two dormant accounts flagged as potentially vulnerable due to exposed keys.
Researchers are already citing XRPL as one of the few major blockchain ecosystems actively preparing for quantum resistance before “Q Day” arrives. As the push toward post-quantum security intensifies, Ripple appears intent on keeping XRPL ahead of the curve rather than reacting to it.
