What Is a Coordinator?

Coordinator is a term used in blockchain technology to refer to a tracking and checking system for validator nodes. It plays a crucial role in ensuring the validity of the distributed ledger by issuing milestones, which are recorded transactions on the blockchain. These milestones are used by validator nodes to verify the accuracy of their copy of the ledger. It is worth noting that not all blockchains have a coordinator client.

IOTA is an example of a blockchain that utilized a coordinator client for ledger verification. The coordinator client added an extra layer of security and ensured the integrity of all copies of the distributed ledger. However, the IOTA foundation has recently eliminated the coordinator client from its system as part of its roadmap.

Many blockchain and cryptocurrency enthusiasts believe that coordinators undermine the decentralized nature of the technology. Since coordinators have the power to influence all copies of the ledger simultaneously, they are seen as a centralizing factor. This contradicts the core ideology of blockchain technology, which emphasizes decentralization. Therefore, blockchains with a coordinator client cannot be considered fully decentralized.

As blockchain technology evolves, new consensus mechanisms are emerging to facilitate full decentralization. In the case of IOTA, the network now relies solely on its Directed Acyclic Graph (DAG) for transaction verification and node validation. Consequently, coordinator clients may not be a viable long-term security solution. However, for nascent projects or those that intentionally prefer a certain level of centralization, a coordinator client can be a useful tool to ensure network security.
