What Is the Concept of “Deterministic” Output in Hashing?
A deterministic output means that for a given input, a hash function will always produce the exact same output hash, every single time. If you input "Bitcoin" into SHA-256, the output hash will be identical today, tomorrow, and forever.
This property is fundamental to cryptocurrency and blockchain integrity, as it allows anyone to independently verify that a transaction or block is valid by re-hashing the data and checking if the result matches the recorded hash.
