Crypto
Validator
A person or computer that locks up crypto to help verify transactions and add new blocks on Proof of Stake blockchains.
Validators replace miners in Proof of Stake systems. They get chosen to propose blocks based on how much they staked. It's way more energy-efficient than old-school mining.It's like being a referee in a big sports league — you stake your reputation (and money) to make fair calls, and you get paid if you do it right.
Real world: On Ethereum, anyone can become a validator by staking 32 ETH, then they help approve transactions and earn rewards for keeping the network honest.
💡 Staking as a validator is an easy way to earn passive income — just make sure you run good hardware and stay online 24/7.
