The Graph project is building a decentralized data network to enable fast access to Ethereum and IPFS data for Dapps. The Graph network is a network of Graph nodes responsible for extracting and indexing data from the Etherum network. There are multiple actors in the Graph network that are incentivized to keep the network secure and provide continuous and efficient data services. Curators deposit GRT tokens into a bonding curve to signal on a specific subgraph, and earn a portion of query fees for their services. This helps Dapp builders build completely decentralized applications without depending on centralized servers.
