Hash

Hash is a fixed-size alphanumeric string generated by applying a cryptographic hash function to input data. It is used to uniquely identify data and ensure data integrity in blockchain networks. Hash functions, like SHA-256, produce a unique hash output for each unique input, making it highly unlikely for two different inputs to produce the same hash. Hashes are widely used in blockchain to verify the integrity of transactions, blocks, and other data by comparing the generated hash with the expected hash value.
