Breakthrough in Quantum Attack: Researcher Claims 1 Bitcoin Bounty

A significant milestone has been achieved in the realm of quantum computing, as an independent researcher has successfully executed the largest public quantum attack to date, breaking a 15-bit elliptic curve key on publicly accessible quantum hardware. This achievement has earned the researcher a 1 bitcoin bounty, valued at approximately $78,000, as part of the Q-Day Prize awarded by quantum security startup Project Eleven. The breakthrough demonstrates the growing capabilities of quantum computers and highlights the potential risks to the security of cryptocurrencies such as Bitcoin, which relies on elliptic curve cryptography to secure transactions. While the broken key is significantly smaller than the 256-bit keys used in Bitcoin, the achievement marks a substantial increase in quantum computing power, with the researcher expanding on the previous public demonstration by a factor of 512 in just seven months. The implications of this development are being closely watched by the cryptocurrency community, with many experts emphasizing the need for post-quantum transition plans to ensure the long-term security of digital assets.
