What is DPoS (Delegated Proof of Stake)?
Crypto Glossary Definition
Invented by Daniel Larimer, it is an alternative consensus mechanism to Proof of Work. A cryptocurrency that uses DPoS votes for a 'witnesses' to secure their computer network. Coin holders vote for 'delegates', who are then responsible for validating transactions and maintaining the blockchain. It's used as a consensus mechanism in various cryptocurrencies such as BitShares, Lisk, EOS, Tezos, Ark, Nano and Cardano.
Why DPoS (Delegated Proof of Stake) Matters
DPoS has token holders vote for a limited set of delegates who do the actual block validation on their behalf, trading some decentralization for higher transaction throughput compared to standard Proof of Stake.
DPoS (Delegated Proof of Stake) in Practice
Consider a blockchain platform designed specifically for fast decentralized exchange trading, where waiting even a few seconds for transaction confirmation would make the exchange uncompetitive against centralized alternatives. Rather than having every token holder validate transactions directly, the network lets holders vote for a limited number of delegates — commonly a few dozen — who take turns producing blocks and validating the chain. A user holding the platform's token doesn't need to run a validator node themselves; they simply cast votes for delegates whose track record and stated policies they trust, similar to electing representatives, and if a delegate performs poorly or acts maliciously, the community can vote them out in the next round. This system, invented by Daniel Larimer and used in BitShares, Lisk, and EOS, achieves significantly higher transaction throughput than standard Proof of Stake because a small, known set of validators can coordinate and confirm blocks much faster than a large, open validator set can. The tradeoff is that power concentrates among the elected delegates, and if a small cartel of them coordinates, they could theoretically censor transactions or collude in ways that a more decentralized, larger validator set would make far harder to pull off.
