Delegated Proof-of-Stake (dPOS)

    Delegated proof-of-stake is a consensus algorithm where token holders can vote for delegates to validate transactions and produce blocks on a blockchain. Block producers are usually selected based on stake weight (those with more tokens have more say in who creates blocks). The delegates holding the most votes have the most power. They tend to produce the most and receive the most rewards. Some protocols may have a built-in mechanism to balance block production and reward so that all delegates have an equal opportunity. Delegated proof-of-stake is an alternative to proof-of-work blockchain because it uses less energy and is more efficient with a tradeoff for some degree of centralization.
