Breakthrough in Quantum Attack: Researcher Claims 1 Bitcoin Bounty

The threat of quantum attacks on cryptocurrency has become more tangible with a recent breakthrough. Quantum security startup Project Eleven awarded a 1 bitcoin bounty to Giancarlo Lelli for breaking a 15-bit elliptic curve key, a significant feat that demonstrates the growing capabilities of quantum computing. This achievement is 512 times larger than the previous public demonstration and has sparked concern among bitcoin developers and the broader community. Elliptic curve cryptography is a crucial component of cryptocurrency, enabling wallets to prove control over funds without revealing private keys. However, quantum computers using Shor's algorithm can potentially compromise this security. Lelli's result, although not an immediate threat to bitcoin, highlights the rapid progress in quantum attacks and the need for post-quantum transition plans. The bitcoin community is exploring migration paths, including the proposed BIP-360, to address the potential risks. As the barrier to running quantum attacks continues to drop, the concern for wallets with visible public keys, estimated to be around 6.9 million bitcoin, becomes increasingly pressing.
