WebHashing is a cryptographic technology that ensures that minor changes are easily detectable. Each blockchain uses hashing, but different blockchains may apply other hashing techniques. We explain how hashing contributes to a blockchain’s immutability, followed by an overview of hashing basics. WebCryptographic hash functions play an important role in modern communication technology. The input to a hash function is a file or stream of any size and the output is a fixed-size digital representation of the file that is normally less than 1KB and serves as the fingerprint of the original file (often called the message digest).
