What is cryptocurrency?
Graph 是一個基於以太坊的索引協議，允許開發人員輕鬆地訪問來自以太坊和 IPFS 等區塊鏈網絡的數據，以高效地運行他們的去中心化應用程序。Aave、Curve 和 Uniswap 等流行的 DApp 都在使用 Graph。
Graph 分析區塊鏈數據並將其存儲到稱為子圖的開放 API 中。DApp 可以使用流行的查詢語言 GraphQL 輕鬆地查詢這些子圖，以立即檢索相關數據。
Graph 的生態系統有四個貢獻者——開發者、管理員、索引者和代理。開發人員在 DApps 中創建和使用子圖；管理員識別哪些子圖對網絡有價值，可以被索引；索引器是完成用戶查詢的 Graph 節點操作符；代理通過將 GRT 委託給索引器來支持網絡。
要成為管理員、索引者或代理併為自己賺取收益，需要持有 GRT 代幣。如果您是一個 DApp 開發人員，您可以購買 GRT，並使用它從圖中獲取有價值的數據。
