A validator is an individual or entity in a Proof of Stake (PoS) blockchain that is responsible for verifying transactions and adding new blocks to the chain. Validators are selected based on the amount of cryptocurrency they stake as collateral.
They help secure the network by ensuring that only valid transactions are recorded, and they earn rewards for their services.
To maintain network integrity, validators risk losing a portion of their stake if they engage in malicious behavior, a process known as slashing.
