Quantum Threat to Crypto Security Reduced, But Clock Keeps Ticking

Researchers have reevaluated the potential impact of quantum computers on Bitcoin and Ethereum's security, reducing their estimated attack vulnerability by 50%. A paper shared with CoinDesk shows that humans and AI agents were able to beat Google's March result on a core calculation used by Shor's algorithm. This breakthrough has added another variable to the 'quantum clock,' which measures how long it would take for a powerful quantum computer to break certain encryption methods.

Shor's algorithm is a method that uses quantum computers to factor large numbers, potentially compromising the security of cryptographic systems like Bitcoin and Ethereum. The researchers' new estimates suggest that the time required to perform such an attack has increased, but the specific timeframe remains unclear.
