what's Project Eleven?
Project Eleven is an applied research lab focused on the intersection of quantum computing and cryptography, developing infrastructure to secure digital assets like Bitcoin against future quantum threats. Founded to address the vulnerability of current cryptographic systems, such as ECDSA used in Bitcoin, the company works on post-quantum solutions that enable users to protect their holdings without requiring immediate protocol changes or on-chain transactions. Their flagship product, Yellowpages, is a cryptographic registry that allows Bitcoin holders to generate quantum-resistant keys, prove ownership of existing addresses, and register these proofs publicly. This proactive approach targets at-risk wallets with exposed public keys, estimated at over 6 million BTC, providing a bridge to quantum-safe standards. Project Eleven also runs initiatives like the Q-Day Prize to demonstrate and quantify quantum risks to elliptic curve cryptography.
Project Eleven raised $20M Series A at $120M valuation, equity with token warrant.
