Breakthrough in Quantum Attack: Researcher Claims 1 Bitcoin Bounty

A significant milestone has been reached in the realm of quantum attacks, with a researcher being awarded 1 bitcoin for successfully breaking a 15-bit elliptic curve key. This achievement, made possible by independent researcher Giancarlo Lelli, marks a substantial leap forward in the field, with the previous public demonstration being 512 times smaller. The bounty, worth approximately $78,000, was awarded by quantum security startup Project Eleven. The breakthrough has sparked concern among bitcoin developers and the broader community, as it brings attention to the potential vulnerability of bitcoin and other major blockchains to quantum attacks. Elliptic curve cryptography, which is used to secure crypto wallets, relies on the difficulty of deriving a private key from its public counterpart. However, quantum computers running Shor's algorithm can potentially exploit this, posing a threat to the security of these wallets. While Lelli's result does not immediately compromise bitcoin, it highlights the need for vigilance and the importance of developing quantum-safe address types. Bitcoin developers have proposed migration paths, including BIP-360, to address this concern. The achievement also underscores the rapid progress being made in quantum attacks, with the barrier to running such attacks in practice continuing to drop.
