A block producer is a decentralized entity responsible for validating transactions and creating new blocks in a blockchain network that uses a Delegated Proof of Stake (DPoS) consensus mechanism. Also known as delegates or witnesses, block producers handle the consensus mechanism and add blocks containing records of transactions on a DPoS network.
EOS is a blockchain network that uses block producers to verify transactions and produce new blocks. Block producers work similarly to miners in a proof-of-work blockchain or as validator nodes in a proof-of-stake network.
A DPoS network achieves consensus more efficiently by randomly selecting a limited number of trustworthy nodes as block producers. The nodes that receive the highest number of votes from other nodes that form the blockchain are elevated to the status of block producers.
