Validator

Beginner

A validator is a participant in a Proof of Stake (PoS) blockchain who verifies transactions and adds new blocks. Validators stake tokens and are rewarded for their service. They are crucial for maintaining network integrity and decentralisation. Validators must behave honestly; misconduct can be penalised by losing part of their staked assets (slashing).
