What Are Validators in Blockchain?

Validators are the nodes that verify transactions on a blockchain network (like Solana). Their role is to ensure the security and integrity of every operation on the network.

Unlike centralized networks (like BSC, which is controlled by Binance and selects its own validators), decentralized networks implement systems that allow nodes to be chosen independently, with no central authority. PoS, or Proof of Stake, is one such validator selection method.
