Breakthrough in Quantum Attack: Researcher Claims 1 Bitcoin Bounty

The threat of quantum attacks on cryptocurrency has become more tangible, as evidenced by the recent achievement of independent researcher Giancarlo Lelli. Lelli was awarded a 1 bitcoin bounty by quantum security startup Project Eleven for breaking a 15-bit elliptic curve key on publicly accessible quantum hardware, a feat that marks a significant milestone in the field of quantum computing. This breakthrough demonstrates the potential vulnerability of elliptic curve cryptography, the underlying technology used to secure funds in crypto wallets. Although the 15-bit key is still far from the 256-bit security used by bitcoin, this achievement underscores the rapid progress being made in quantum computing and highlights the need for the development of quantum-safe address types. The implications of this breakthrough are substantial, with approximately 6.9 million bitcoin, or one-third of the total supply, potentially at risk due to exposed public keys. As a result, bitcoin developers are exploring migration paths, including the proposed BIP-360, to ensure the long-term security of the network.
