Recent advancements in quantum computing pose a significant threat to the security of blockchain networks, particularly Bitcoin. Quantum computers, with their unparalleled computational power, have the potential to dismantle the cryptographic algorithms that currently protect these networks. To address this pressing issue, Project Eleven, a foremost research and advocacy firm specializing in quantum computing, has initiated the Q-Day Prize. This global competition offers a reward of one bitcoin (BTC) to the first team that successfully breaks an elliptic curve cryptographic (ECC) key, which is crucial for the security of the Bitcoin network, using Shors algorithm on a quantum computer.

Shor's algorithm represents a groundbreaking approach in quantum computing, enabling these advanced machines to factor large numbers into their prime components with remarkable efficiency. This capability means that quantum computers could potentially breach cryptographic systems such as RSA and elliptic-curve cryptography, both integral to the security protocols employed in Bitcoin and a multitude of other blockchain networks.

The urgency surrounding this contest is underscored by the rapid pace of advancements in quantum computing technology, suggesting that a fully functional quantum computer could be just a few years away from becoming a reality. Project Eleven has highlighted the vulnerabilities in the current system, identifying over 10 million Bitcoin addresses with non-zero balances that could be at risk of quantum attacks, thereby raising alarms within the cryptocurrency community.

In response to these threats, members of the Bitcoin community are actively exploring possible solutions to bolster security against quantum incursions. As previously reported by
