Researcher Claims 1 Bitcoin Prize for Achieving Largest Quantum Attack on Underlying Technology

A significant breakthrough has been made in quantum attacks, with independent researcher Giancarlo Lelli being awarded a 1 bitcoin prize for breaking a 15-bit elliptic curve key on publicly accessible quantum hardware. This achievement marks a substantial increase from the previous public demonstration, showcasing the rapid progress in this field. The underlying math that enables a crypto wallet to prove ownership of funds without revealing the private key has been successfully attacked using quantum computers running Shor's algorithm. Although this breakthrough does not immediately threaten bitcoin, which uses 256-bit elliptic curve security, it highlights the need for the crypto community to be vigilant and proactive in addressing potential quantum threats. The winning submission was made using cloud-accessible hardware, demonstrating that significant advancements can be achieved without relying on national laboratories or private quantum chips. As the resource requirements for such attacks continue to drop, the concern for wallets with publicly visible keys grows, with an estimated 6.9 million bitcoin at risk. In response, bitcoin developers have proposed migration paths, including the introduction of quantum-safe address types, while other cryptocurrencies like Ethereum, Tron, StarkWare, and Ripple have also published post-quantum transition plans.
