blockchain validator
Also called a "blockchain verifier," validators are computers that maintain the blockchain's integrity by constantly computing the linkage from the first block to the last. There is generally an abbreviated version of the blockchain for this purpose that is much smaller than the full chain, which contains every transaction.Validators for a public blockchain are maintained primarly by volunteers, who typically dedicate a computer to the process. There are thousands of validation nodes for a major blockchain such as Bitcoin or Ethereum. See blockchain and cryptographic hash function.
validate
To prove something to be sound or logical. Also to certify conformance to an accepted standard. Contrast with verify.For example, data entry validity checking determines whether the data make sense (numbers fall within a range, numeric data are all digits, etc.), but "validity" checking does not "verify" that the data are correct. Even if the check digit in a customer account number is determined to be a valid number, it may still be the wrong number for that individual. In practice, the terms "validate" and "verify" are used synonymously. See validity checking, check digit and HTML validator.
