How is SHA-256 used with Bitcoin?
SHA-256 (Secure Hash Algorithm 256-bit) is a cryptographic hash function that plays several critical roles in Bitcoin’s architecture and security model. Core Functions in Bitcoin...
How does Grover’s Algorithm reduce SHA-256 security from 256 bits to 128 bits?
Grover’s algorithm reduces SHA-256’s security from 256 bits to 128 bits through its ability to search unsorted databases quadratically faster than classical algorithms. Here’s how...
