Blockchain Fundamentals

Validator

A validator is a network participant responsible for verifying transactions and adding blocks in Proof of Stake and other consensus mechanisms. Unlike miners, validators are selected based on their stake in the network. They help maintain blockchain integrity by confirming data accuracy and preventing malicious activity. Validators earn rewards for honest behavior and may lose stake if they act against the network’s rules. They are essential in securing and scaling modern blockchain systems like Ethereum 2.0, Cosmos, and Polkadot.
