Grover's Algorithm
Grover's algorithm is a quantum computing algorithm that provides a quadratic speedup for searching unsorted databases and brute-forcing symmetric cryptographic functions.
Applied to Bitcoin, Grover's algorithm could theoretically reduce SHA-256's effective security from 256 bits to 128 bits. However, 128-bit security remains enormously strong and is not considered a practical threat. Grover's algorithm is distinct from Shor's algorithm, which targets public-key cryptography and poses the more significant (though still distant) threat to Bitcoin.
