Marcus Rein, Senior Developer Relations at Edge & Node, introduces building on The Graph and Hypergraph at ETH Global. The Graph is a decentralized indexing and querying protocol for blockchain data, featuring 100+ indexers. He outlines $10,000 in hackathon prizes across tracks for building with Token API, Substreams, Subgraphs, Hypergraph, and the GRC20TS library. Hypergraph is a local-first, full-stack Web3 app framework leveraging knowledge graphs for composable, privacy-enabled data. Key features include public/private spaces, end-to-end encryption, standardized IDs, and real-time sync via a sync server. Marcus demos CRUD operations on entities in Hypergraph, showing schema definition, mapping, and front-end integration. He explains how Hypergraph enables collaborative, composable apps with both blockchain and non-financial data, and answers questions on privacy, authentication, data sync, decentralization, and verifiability. He encourages participants to explore use cases like crypto directories, DApp registries, and DAO governance explorers. 00:00 Introduction 00:34 Overview of The Graph and Prizes 01:16 Prize Tracks and GRC20TS Library 02:36 Hypergraph Overview and Features 04:43 Knowledge Graphs Explained 06:14 Spaces: Public and Private Data 07:37 Sync Server and Composability 08:31 Hypergraph Live Demo: Setup 09:25 Exploring Public Spaces and Entities 10:31 Schema, Mapping, and Data Integration 13:49 Adding and Composing Data 14:05 Creating and Publishing Entities 15:20 Managing Private and Public Spaces 16:37 CRUD Operations in Hypergraph 17:52 Composable Apps and Use Cases 18:27 Example Ideas and Docs 19:10 Q&A: Privacy, Sync, and Authentication 21:04 Smart Contracts, Permissions, and Data Storage 22:25 Sync Server, Decentralization, and Verifiability 24:25 Exploring Spaces and Datasets 25:19 Censorship, IPFS, and Final Q&A _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 🇺🇸 *ETHGlobal New York* This workshop is specifically for ETHGlobal New York, a 3-day hackathon held August 15-17, bringing together the most skilled web3 developers, designers and product builders from all around the globe for a weekend-long adventure to advance the Ethereum ecosystem!

Clip The video discusses the implementation of multiple APIs in the context of blockchain technology. It suggests that pre-confirmation gateways, which are considered sophisticated parties, should be responsible for this task rather than L1 proposers, who are assumed to be less sophisticated. The speaker also mentions that standardizing this process is important in the future.
