A mathematical function that takes an input and produces a fixed-size output, used to confirm that all validators are talking about the same transactions.
In the realms of coding, cryptocurrency, and XRPL, a hash refers to a unique alphanumeric string generated by a hash function. It serves as a digital fingerprint of data, representing its contents in a condensed and fixed-size format. Hashes are commonly used for data integrity verification, password storage, digital signatures, and block validation. By applying cryptographic algorithms, hashes ensure the security and immutability of information, making them essential for maintaining the integrity and trustworthiness of coding, cryptocurrency transactions, and XRPL operations.
