Theory & Core Foundations

SHA-256 (Secure Hash Algorithm 256-bit) produces a unique 64-character hexadecimal digest. Its core strength is the Avalanche Effect: changing even a single bit of input flips approximately 50% of the output bits at random.

Mathematical Foundations

Cryptographic compression functions and Proof-of-Work difficulty targets.

\text{SHA-256}(\text{Data} + \text{Nonce}) < \text{Target Difficulty}

How The Simulation Works
