Cryptocurrency hash explained
WebJan 17, 2024 · A hash function maps any type of arbitrary data of any length to a fixed-size output. It is commonly used in cryptography since it is a cryptographic function. They are efficient and are well-known for one property: they are irreversible. It's a one-way function that's only meant to work in one direction. WebJul 8, 2024 · The validity of each cryptocurrency’s coins is provided by a blockchain. A blockchain is a continuously growing list of records, called blocks, which are linked and secured using cryptography. Each block typically contains a hash pointer as a link to a previous block, a timestamp and transaction data.
