Have you ever wanted to dip your toes into web3 development and blockchain data but don't know how? Join us to learn how blockchain data can be easily queried with GraphQL! Subgraphs APIs and the tooling built around them are all open source, making it easy for developers to build decentralized applications (dapps). Within the world of web3 there are many different ways to use smart contracts, so Subgraphs are modular APIs enabling developers to build for any use case. These subgraphs can be queried via The Graph, a decentralized network for accessing blockchain data. In this presentation we will explore: Practical aspects of accessing blockchain data using Subgraphs, including the basics of building a GraphQL schema Discuss efficient Data optimization Utility of GraphQL for blockchain data Elements of decentralization and data Learn how Subgraphs simplify the data extraction from blockchains, optimize data handling, and enhance query flexibility. Join us to understand how these elements work together to make blockchain data more accessible and manageable.
