Breakthrough in Quantum Attack: Researcher Claims 1 Bitcoin Bounty

The threat of quantum attacks on bitcoin has become more pressing, as a recent breakthrough has demonstrated the ability to break a 15-bit elliptic curve key on publicly accessible quantum hardware. This achievement, made by independent researcher Giancarlo Lelli, has earned him a 1 bitcoin bounty worth approximately $78,000. The attack, which utilizes Shor's algorithm, has significant implications for the security of bitcoin and other cryptocurrencies that rely on elliptic curve cryptography. Although the broken key is significantly smaller than the 256-bit keys used by bitcoin, the demonstration highlights the rapidly advancing capabilities of quantum computing and the need for the development of quantum-resistant cryptographic protocols. The bitcoin community is taking steps to address this threat, with proposed solutions including the implementation of quantum-safe address types and post-quantum transition plans.
