Ethereum is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of downtime, censorship, fraud or third-party interference. Ethereum uses a public blockchain and its own cryptocurrency called Ether to enable users to develop and deploy distributed applications and programs. It is an open source platform that allows developers to write code that controls digital assets, create applications, and store data in a secure and decentralized manner. Ethereum also provides the ability to create and manage digital tokens, which can be used for various purposes such as fundraising, voting, and more.

In this workshop, you'll learn how to build your first full stack dapp on the Ethereum blockchain, reading and writing data to the network, and connecting a front end application to the contract you've deployed. By the end of the workshop, you'll understand how to set up a full stack development environment, run a local node, and interact with any smart contract using React, HardHat, and Ethers.js.

The Graph is an indexing protocol for querying networks like Ethereum, IPFS, and other blockchains. Anyone can build and publish open APIs, called subgraphs, making data easily accessible.

In this workshop you’ll learn how to build a subgraph that indexes NFT blockchain data from the Foundation smart contract. We’ll deploy the API, and learn how to perform queries to retrieve data using various types of data access patterns, implementing filters and sorting.

By the end of the workshop, you should understand how to build and deploy performant APIs to The Graph to index data from any smart contract deployed to Ethereum.

Author, open source developer working in blockchain space with Edge & Node and The Graph Protocol.
This Talk is about building GraphQL APIs on top of Ethereum and the Ethereum virtual machine. The graph is an indexing protocol for querying blockchain networks like Ethereum and IPFS. Developers can build APIs called subgraphs to efficiently index data and make it available for querying from frontend applications. The graph serves over 1 billion queries per day and is used in various Web3 applications including DeFi, gaming, and NFT marketplaces. The process involves defining the data model using the GraphQL schema and contract addresses, deploying and testing the subgraph, and using a GraphQL client to query the subgraph.
