Invented by Daniel Larimer, Delegated Proof-of-Stake (DPoS) is an alternative consensus mechanism that requires coin holders to vote for “delegates”, who are then responsible for validating transactions and maintaining the blockchain. DPoS is an alternative to the more commonly known, Proof-of-Stake (PoS) model which requires miners to put up a stake in a cryptocurrency in-order for them to be able to validate transactions.
