Breakthrough in Quantum Attack on Cryptographic Technology Earns Researcher 1 Bitcoin Bounty

The threat of quantum attacks on bitcoin has become more tangible with the latest achievement by independent researcher Giancarlo Lelli, who has been awarded a 1 bitcoin bounty by quantum security startup Project Eleven. Lelli broke a 15-bit elliptic curve key on publicly accessible quantum hardware, a feat that surpasses the previous public demonstration by a factor of 512. This breakthrough has significant implications for the security of bitcoin and other major blockchains, as it demonstrates the growing capabilities of quantum computers in attacking cryptographic keys. 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 break this security. While Lelli's achievement does not pose an immediate threat to bitcoin, which uses 256-bit elliptic curve security, it highlights the need for the development of quantum-safe address types and post-quantum transition plans. The bounty awarded to Lelli is a significant milestone in the ongoing effort to assess the vulnerability of cryptographic systems to quantum attacks.
