A blockchain validator verifies transactions in the proposed blocks and helps build new blocks. In return, they receive cryptocurrency.
Validators are responsible for adding new blocks and verifying transactions in proposed blocks, thus playing a vital role in the functioning of the blockchain.
A validator is crucial in validating transactions in blockchain consensus mechanisms like proof-of-stake (PoS) and proof-of-authority (PoA). They check whether new transactions align with the network’s rules and ensure that the sender has adequate funds to complete the transaction.
