Validator

One who is in charge of examining blockchain transactions is known as a validator. Transactions are added to the distributed ledger after they have been validated.

In systems using the proof of work (PoW) algorithm, such as Bitcoin, validators—also referred to as miners—solve challenging computational arithmetic problems to earn the ability to validate transactions and collect rewards for their “work”. Validators receive incentives in proof-of-stake (PoS) systems like Avalanche as long as they stake the network’s token (AVAX) and correctly engage in the network. By requiring value to be locked up in the network in order to take part in the consensus decisions, this approach aids in network security.
