**Headline:** Project Eleven Launches Q-Day Prize: 1 BTC for Breaking Bitcoin’s ECC Keys with Quantum Computing
In a groundbreaking initiative, Project Eleven, a research organization focused on quantum computing, has unveiled the Q-Day Prize. This global challenge offers a reward of 1 BTC to the first team that successfully breaks an elliptic curve cryptographic (ECC) key using Shor’s algorithm on a quantum computer. The deadline for this challenge is set for April 5, 2026, and it specifically targets the Elliptic Curve Digital Signature Algorithm (ECDSA), which is fundamental to Bitcoin’s security framework.
The urgency of this challenge stems from the potential risks posed by advancements in quantum computing. While discussions about the threats of quantum technology to current cryptographic systems have been ongoing, Project Eleven aims to transform these theoretical concerns into tangible risks by promoting practical demonstrations of cryptographic vulnerabilities. Currently, over 6.2 million BTC, valued at nearly $500 billion, are stored in wallets with exposed public keys, making them susceptible to quantum attacks if such capabilities are realized.
Alex Pruden, CEO and co-founder of Project Eleven, emphasized the uncertainty surrounding the timeline for a quantum “doomsday” scenario for existing cryptography. “The Q-Day Prize is designed to take a theoretical threat from a quantum computer and turn that into a concrete model,” he stated.
Recent advancements in quantum computing have heightened the urgency of this initiative. Notably, Google’s ‘Willow’ chip recently completed a complex computation in just five minutes—an operation that would take supercomputers 10 septillion years. This achievement highlights significant progress in error correction. Additionally, Amazon’s ‘Ocelot’ and Microsoft’s ‘Majorana 1’ chips have made notable advancements, while PsiQuantum secured $750 million in Q1 2025 to enhance photonic chip design and optimize Shor’s algorithm.
The accessibility of quantum computing is also expanding, with cloud-based services from major providers like IBM, AWS, Google, and Alibaba making this technology more available to researchers and developers.
The Q-Day Prize continues a legacy of cryptographic benchmarking challenges, reminiscent of the RSA Factoring Challenge in 1991 and Hal Finney’s 1995 SSL cipher challenge, both of which were pivotal in assessing cryptographic resilience. “This is an open call to the boldest minds in quantum,” Pruden added. “Prove what’s possible, and help us secure the future of digital assets.”
