What are Blockchain Validators?

Validators are the nodes that verify transactions in a blockchain network (such as. Solana). Their role is to ensure the security and integrity of all transactions.

Unlike centralized networks (such as BSC, which is controlled by Binance and chooses its validators), decentralized networks implement systems so that nodes can be chosen independently and without central authority. The PoS or Proof of Stake is a method of choosing validators.
