Understanding a Coordinator in Blockchain
Coordinator refers to a component that serves as a tracking and verification system for validator nodes within a blockchain network.
The coordinator issues milestones, which are essentially recorded transactions on the blockchain.
Validator nodes utilize these milestones to verify the correctness of their copy of the distributed ledger.
It’s important to note that not all blockchains incorporate a coordinator client.
Enhancing Decentralization in Blockchain
The decision to remove the coordinator client aligns with the belief among many blockchain and cryptocurrency enthusiasts that coordinators can impede the technology’s decentralized nature.
Since coordinators possess concentrated power to influence all copies of the ledger in the network simultaneously, they are seen as a centralizing element.
Consequently, blockchains that rely on a coordinator client cannot achieve complete decentralization.
