The Graph is an indexing protocol that allows blockchain applications like Ethereum and IPFS to collect, process, and retrieve data in a verifiable way. The protocol is open-source, making it easier for developers to build and publish open APIs called subgraphs. GRT is the name and ticker symbol of its native token. The Graph collects, analyzes, and sorts blockchain data using Graph nodes. Graph nodes are responsible for constantly scanning blocks and smart contracts on the blockchain. When applications add new data to the blockchain, Graph nodes categorize the information into their respective subgraphs. End users can then search for relevant data within subgraphs. By enabling DeFi applications to communicate with each other quickly and securely, The Graph solves problems such as chain reorganization and query fulfillment capacity. Some of the most popular DApps leveraging the indexing mechanism of The Graph are Aave, Curve, and Uniswap. What sets The Graph apart is how it involves GRT tokens at each stage of the indexing process. The Graph relies on four separate network participants: indexers, curators, delegators, and consumers. These four network actors are vital to running the open-source protocol and are as follows. Indexers act as the node operators of The Graph. Indexers can stake GRT on the platform and run a Graph Node. Their primary function is to provide indexing services to signaled subgraphs. This process rewards indexers with GRT tokens, who can also set their own fees for providing indexing services. Indexers compete with other indexers to ensure a quality service. Curators are responsible for ensuring the quality of the services provided by indexers. First, they assess which subgraphs offer accurate data. Second, curators use their GRT tokens to signal which subgraphs are worth indexing. Finally, curators receive rewards directly proportional to the popularity of signaled subgraphs. Delegators assist in securing the network by delegating their GRT tokens to indexers. This helps Graph nodes to fulfill their indexing services. In return, delegators receive GRT tokens rewards from indexers in proportion to their delegation.
