A user that participates in the transaction verification process on a proof-of-stake blockchain.

A validator is a crypto user that participates in the validation processes necessary for transactions on proof-of-stake (PoS) blockchain networks. This role is the equivalent of a miner in proof-of-work (PoW) networks, except that in the former consensus system, the user needs to stake a specific number of tokens before they can take up the role of a validator.

Validators generally earn a bit more than ordinary users on any blockchain that uses the PoS consensus mechanism. Moreover, it is on account of their work that the PoS framework is generally more efficient and transparent compared to the PoW framework.
