A validator is a participant in a blockchain network who is responsible for verifying transactions and adding new blocks to the blockchain, typically within Proof of Stake systems. Validators help maintain the security and integrity of the network.
A validator confirms transactions and helps create new blocks on the blockchain.
In Proof of Stake (PoS) networks, validators are chosen to validate transactions based on the amount of cryptocurrency they have staked as collateral. Instead of using computational power like miners in Proof of Work, validators are selected to propose and confirm blocks. If they act honestly, they earn rewards such as transaction fees or newly issued tokens. However, if they behave maliciously or make errors, they can lose part of their staked assets through a process known as slashing. Validators are essential for keeping the network decentralized, secure, and functioning efficiently, but participation often requires technical knowledge and a minimum staking amount.
Short example:
Suppose you stake cryptocurrency in a PoS network.
You are selected as a validator to verify transactions and add a new block.
By doing this correctly, you earn rewards, but if you act dishonestly, you risk losing part of your stake.
