Project 11 has launched a global challenge to test quantum computing’s real-world impact on Bitcoin security. The team is offering a 1 BTC reward to anyone who can use an actual quantum computer – not a simulator to break a specially created Bitcoin private key. This challenge aims to evaluate current quantum capabilities and push the crypto community to prepare for future threats.
Crack the Key and Win 1 Bitcoin
The bounty, called the Q-Day Challenge, is open to any individual or team capable of running Shor’s algorithm on real quantum hardware. The task is to break a 256-bit elliptic curve key created for this event. The deadline is April 5, 2026. The first verified submission wins 1 BTC.
Participants must use actual quantum processors. Simulations or classical methods will be disqualified. Full technical documentation is required to validate submissions.
This challenge is not just about the reward. It’s about identifying how close we are to real quantum threats and preparing blockchain networks for what comes next.
Why the Quantum Bitcoin Bounty Matters
Bitcoin, like most cryptocurrencies, relies on public key cryptography. While this system is currently secure against classical attacks, quantum computing could change that. Shor’s algorithm, when implemented on scalable quantum machines, has the potential to break these protections.
Project 11 believes the crypto space isn’t acting fast enough. By putting 1 BTC on the line, they aim to spark public interest and accelerate industry-wide discussions about quantum readiness. The project hopes to shift crypto developers toward post-quantum security planning.
Quantum Computers Are Not Ready—Yet
Most experts agree that today’s quantum computers don’t have enough qubits to pose a serious threat to Bitcoin. However, progress is constant. Major tech firms are scaling up quantum hardware year after year. If development continues at this pace, working quantum machines with thousands of error-corrected qubits may arrive sooner than expected.
This challenge serves as a litmus test. If no one wins, it confirms that current systems are still safe. But if someone does crack the key, the implications could be massive. Blockchain systems would need immediate upgrades to protect funds and user data.
Millions of Bitcoins at Risk
Roughly 20% of all Bitcoin is stored in wallets with exposed public keys. These funds are especially vulnerable if quantum attacks become feasible. These older addresses could be the first to fall if quantum systems mature.
Project 11’s bounty highlights the importance of migrating funds and updating protocols before a threat becomes real. Waiting until after an exploit would be far too late. This bounty is a chance to stay ahead of the curve.
Community Reactions to the 1 BTC Quantum Bounty
The announcement has stirred intense discussions in both crypto and quantum circles. Some see the bounty as irresponsible. Others view it as a bold and necessary wake-up call. Developers, security researchers, and cryptographers have started debating the timeline of quantum threats more seriously.
Even failed attempts will produce valuable data. Every documented process, success or not, brings new insights into how quantum code interacts with blockchain encryption. That data can inform better future protections.
Post-Quantum Crypto Is Gaining Ground
While Bitcoin still uses elliptic curve cryptography, some newer blockchain platforms are exploring post-quantum security. These networks are experimenting with signature schemes that resist quantum decryption, including lattice-based and hash-based systems.
Project 11 hopes its bounty will push Bitcoin developers to speed up research in this area. Post-quantum migration is no longer optional it’s becoming a necessity. The earlier the transition begins, the smoother it will be.
What If Someone Wins?
If a team successfully cracks the key using quantum hardware, it will prove that Bitcoin’s current system is outdated. Trust in existing wallets could collapse. Emergency forks and mass migrations might follow. Users would need to move assets into safer protocols immediately.
The fallout would be chaotic but also transformative. A successful crack would force the entire industry to rethink how it protects digital assets. Security models would shift overnight. The cost of inaction would be felt across every major chain.
A Wake-Up Call for the Crypto Industry
The Q-Day Bounty isn’t about panic. It’s about preparation. Quantum computing is evolving, whether crypto is ready or not. This public experiment forces the question: are we building secure systems for the future, or clinging to the past?
Project 11 wants answers now, not after the damage is done. This challenge is a unique chance to gather proof and strengthen the space. Even if the key holds firm, the lessons learned will help secure blockchain ecosystems for decades to come.
