Project Eleven Awards 1 BTC Q-Day Prize for Largest Quantum Attack on Elliptic Curve Cryptography to Date

Project Eleven awarded 1 BTC to Giancarlo Lelli for breaking a 15-bit elliptic curve key using publicly accessible quantum hardware, marking a 512x improvement over previous efforts. The breakthrough demonstrates a quantum attack method that could threaten Bitcoin, Ethereum, and $2.5 trillion in ECC-secured digital assets.
