elected validator consensus model
Delegated Proof of Stake (DPoS) is a consensus mechanism designed to enhance the scalability and efficiency of traditional Proof of Stake systems. In DPoS, token holders vote to elect a limited number of trusted validator nodes—called delegates or block producers—who are responsible for validating transactions and creating new blocks.
This system reduces the number of participants needed for consensus, allowing for faster transaction processing and lower energy usage, while still maintaining decentralization through community voting. Delegates can be voted in or out based on performance, promoting accountability.
Use Case: A blockchain network using DPoS allows token holders to vote for 21 block producers. These elected validators process transactions rapidly, and if one underperforms or acts maliciously, the community can vote them out and replace them with a more reliable delegate.
Key Concepts:
- Proof of Stake — The foundational consensus model that DPoS builds upon and optimizes.
- Validator Node — Elected delegates responsible for block production and transaction validation.
- Voting Power — Token holders use their stake to vote for trusted validators.
- Governance — Community-driven process for electing and removing delegates based on performance.
Summary: Delegated Proof of Stake balances speed, efficiency, and decentralization by empowering token holders to elect a small group of validators. Popular blockchains like EOS, TRON, WAX, and BitShares use DPoS for high-throughput applications requiring fast transaction finality and lower energy consumption than traditional consensus models.
