WebSep 19, 2024 · A cryptographic hash is a function that outputs a fixed-size digest for a variable-length input. A hash function is an important cryptographic primitive and extensively used in blockchain. For example, SHA-256 is a hash function in which for any variable-bit length input, the output is always going to be a 256-bit hash. WebEach block includes the cryptographic hash of the prior block in the blockchain, linking the two. The linked blocks form a chain. [3] This iterative process confirms the integrity of the …
