- Project Eleven has launched the Q-Day Prize, offering 1 BTC to the first team that can break Bitcoin’s cryptography using a quantum computer.
- The contest highlights growing concerns about quantum threats to Bitcoin, as solutions like QRAMP and CGBS face challenges due to the need for a hard fork.
A new frontier in digital security is emerging as Project Eleven launches the Q-Day Prize, a high-stakes competition that challenges teams across the globe to break Bitcoin’s cryptographic shield using quantum computing. The prize? A single bitcoin (BTC) awarded to the first team that successfully exploits an elliptic curve cryptographic (ECC) key—the very algorithm securing the Bitcoin network.
At the heart of this competition lies Shor’s algorithm, a powerful quantum method capable of efficiently factoring large numbers into their prime factors. In theory, this could unravel ECC and RSA, exposing vulnerabilities in Bitcoin and other blockchain technologies. While the challenge provided by Project Eleven uses a simplified, “toy” version of Bitcoin’s cryptography, it spotlights real concerns: quantum computing, advancing at a rapid pace, may soon pose a tangible threat to billions of dollars of digital assets.

The implications of such a breakthrough stretch far beyond the contest itself. With over 10 million Bitcoin addresses holding non-zero balances identified as potentially vulnerable, the possibility of a quantum attack has ignited urgency within the Bitcoin community. In response, proposals such as the Quantum-Resistant Address Migration Protocol (QRAMP) have been introduced. QRAMP advocates for a sweeping, network-wide transition to post-quantum cryptography—a move that would necessitate a hard fork and demand wide consensus, a challenging task in the decentralized Bitcoin ecosystem.
Another intriguing solution comes from quantum startup BTQ, which proposes an alternative to Bitcoin’s conventional Proof of Work: the Coarse-Grained Boson Sampling (CGBS) method. This approach leverages quantum computing to create distinctive photon patterns, replacing traditional mining puzzles with quantum-based sampling tasks. However, like QRAMP, the implementation of CGBS would also require a major, consensus-driven shift in the Bitcoin protocol.
The Q-Day Prize not only serves as a testing ground for quantum advances but also as a wake-up call for the broader digital currency community. It underscores the race against time: as quantum computers inch closer to practical viability, securing Bitcoin might depend on the community’s willingness to embrace radical changes before it’s too late.
