Breakthrough in Quantum Attack: Researcher Claims 1 Bitcoin Bounty for Cracking Elliptic Curve Key

The threat of quantum attacks on bitcoin has become more tangible, as a researcher has successfully cracked a 15-bit elliptic curve key, a crucial component of the cryptocurrency's underlying technology. This achievement, made possible by quantum startup Project Eleven's Q-Day Prize, has significant implications for the security of bitcoin and other major blockchains. The cracked key, derived from its public counterpart, demonstrates the vulnerability of elliptic curve cryptography to quantum attacks. Although bitcoin's 256-bit elliptic curve security remains unbroken, this milestone marks a substantial step forward in the development of quantum attacks, with the potential to compromise the security of wallets with publicly visible keys. As the barrier to running such attacks continues to drop, the need for post-quantum transition plans, such as those proposed by bitcoin developers, becomes increasingly urgent.
