The design of SHA-256 is based on principles such as:
1. **Avalanche Effect**: A small change in the input produces a significant change in the output.
--> this is just volatility. ie output has large delta change.
2. **Diffusion and Confusion**: The mixing of bits through numerous rounds ensures that the output is well-distributed and lacks discernible patterns.
--> this is just obfuscation
its just volatile determinism. the pattern exists but it has not been discovered yet.
pseudo randomness leaves pattern. when there is a pattern, there is a trace. cryptography is weak.
