Project Eleven, a specialist in post-quantum cryptography, has announced a strategic collaboration with the Solana Foundation to fortify the Solana network against future quantum computing threats. Announced on December 16, 2025, this initiative marks a proactive step to ensure the long-term security of one of the world's leading blockchain ecosystems.
The engagement involved a comprehensive threat assessment led by Project Eleven, analyzing potential vulnerabilities in Solana's core infrastructure, user wallets, validator security, and cryptographic foundations. Crucially, the company has already deployed a functioning post-quantum digital signature system on a Solana testnet. This prototype successfully demonstrates that end-to-end quantum-resistant transactions are both practical and scalable using current technology.
Matt Sorg, VP of Technology at the Solana Foundation, emphasized the forward-looking nature of the effort: "Our responsibility is to ensure Solana remains secure not just today, but decades into the future... Efforts like Project Eleven’s reflect early, concrete steps to strengthen the network and stay at the forefront, ensuring Solana’s resiliency long-term." He also noted that this work aligns with the ecosystem's broader 2025 roadmap, which includes the release of a second client and a state-of-the-art consensus mechanism.
Alex Pruden, CEO of Project Eleven, praised Solana's early investment in quantum security: "Solana didn’t wait for quantum computers to become a headline problem. They invested early, asked the hard questions, and took actionable steps today. The results show that post-quantum security on Solana is viable with today’s technology." The company is developing specialized tooling, monitoring systems, and migration strategies for multiple leading protocols, positioning itself at the intersection of advanced cryptography and real-world blockchain engineering.
This partnership is seen as part of a broader industry shift towards quantum-safe infrastructure. Experts warn that blockchains relying on classical cryptographic signatures could eventually be vulnerable to quantum attacks, risking fund theft and network manipulation. Project Eleven will continue to support the Solana ecosystem as it evaluates migration paths and standards for adopting post-quantum cryptographic primitives.
