Delegated Proof of Stake (DPoS) | cryptocurrencies, blockchains & live prices

Delegated Proof of Stake (DPoS) is a consensus mechanism where token holders vote to elect a limited number of delegates (also called block producers or witnesses) who are responsible for validating transactions and producing new blocks. Rather than every token holder participating directly in consensus, the community democratically selects a small group of trusted delegates, typically between 21 and 101. The voting power of each token holder is proportional to the number of tokens they hold, and delegates can be voted out if they underperform or act maliciously.

DPoS is designed for high performance and scalability. By limiting the number of block producers, the network can achieve significantly faster block times and higher transaction throughput compared to traditional PoW or PoS systems, often processing thousands of transactions per second. This efficiency makes DPoS well-suited for applications requiring near-instant confirmations. However, the limited number of delegates raises concerns about centralization, as power becomes concentrated among a small group. Vote buying and cartel formation among delegates are additional risks that some DPoS networks have encountered in practice.

EOS is one of the most prominent blockchains using DPoS, operating with 21 elected block producers. Tron also employs a DPoS model with 27 Super Representatives who produce blocks and govern the network. Other notable DPoS implementations include Lisk, Ark, and BitShares, which was created by Dan Larimer, the inventor of the DPoS concept. The mechanism has proven particularly popular for blockchains focused on high-speed decentralized applications and social media platforms.
