In this regard, the protocol uses a “one-way” hash function to convert an input with any length into an output with a fixed-length named hash value. When a new transaction is conducted, cryptography links it to previous ones; that is how blockchain networks are provided with resilience ...

A cryptographic hash function is a mathematical function used in cryptography. Typical hash functions take inputs of variable lengths to return outputs of a fixed length. A cryptographic hash function combines the message-passing capabilities of hash functions with security properties. Key Takeaways Ha...
