Validator
A participant in a Proof of Stake (or similar) system who proposes and attests to blocks, often bonded by a stake.
Validators run nodes that participate in consensus by proposing blocks and attesting to others’ blocks. They usually lock up a stake that can be penalized for misbehavior or downtime.
