Project Eleven is emerging as one of the most important ventures in the quantum era of cryptography. As quantum computers inch closer to breaking today's cryptographic standards, Project Eleven is racing to equip the blockchain world—especially Bitcoin—with quantum-resistant solutions. Their flagship product, Yellowpages, is a crucial first step in building a post-quantum security layer for digital assets.
What is Project Eleven and why does it matter now?
Project Eleven was founded in 2024 with a singular mission: to build real-world tools that can withstand the advent of cryptographically relevant quantum computers (CRQCs). With experts warning that Bitcoin's elliptic curve cryptography (ECC) could be broken by future quantum machines, the project is offering tangible ways to future-proof ownership—before it's too late.
How does Yellowpages help secure Bitcoin from quantum attacks?
Yellowpages (yellowpages xyz) allows users to generate quantum-resistant key pairs and link them cryptographically to their existing Bitcoin addresses. The beauty of this system is that it doesn't require immediate on-chain action or protocol changes. Instead, users can register a quantum-resilient proof of ownership today, ensuring control even in a post-quantum world.
What is the Q-Day Prize and why is it important?
Project Eleven has launched a bold challenge: it will award 1 BTC to the first team to break a toy Bitcoin key using Shor's algorithm on a quantum computer. This prize serves two purposes—pushing forward quantum computing research and emphasizing the urgency of the threat.
Who is backing Project Eleven and what's next?
On June 19. 2025. Project Eleven secured $6 million in seed funding. Variant Fund and Quantonation co-led the round, marking Quantonation's first foray into crypto. Castle Island Ventures, Nebular, and Formation also participated. The funds will support team expansion and continued development of quantum-secure tools.
Who's behind the project?
CEO Alex Pruden, a former military officer and cryptography advocate, co-founded Project Eleven alongside Conor Deegan, VP of Engineering. Their leadership blends technical depth with a mission-driven urgency to protect digital assets before CRQCs become reality.
Conclusion
Project Eleven is preparing the crypto world for a future many are still ignoring. With Yellowpages live and a strong funding round behind them, their post-quantum roadmap could define the next era of Bitcoin security. As Q-Day looms, Project Eleven is leading the charge to ensure Bitcoin and other digital assets survive it.
