Algorithm Information: SHA-256

SHA-256 — what this algorithm is and how it works.

SHA-256 is a cryptographic hash function. Fractal Bitcoin relies on it for proof-of-work consensus. This algorithm processes input data of any length and produces a fixed hash value, ensuring security and integrity in the mining process.
