Intro to Building on The Graph and Hypergraph I Kevin Jones

Sun, Nov 2, 2025, 12:00 AM

Kevin Jones from Edge & Node introduces The Graph as a decentralized indexing layer for blockchain data, emphasizing its evolution beyond subgraphs to include token APIs, MCP servers, Substreams, and Hypergraph. For the hackathon, developers are encouraged to build with these newer tools to qualify for bounties. He explains how Substreams enables real-time blockchain data streaming to external databases, while Hypergraph allows developers to build knowledge graph-based applications with private, encrypted, and verifiable data. The platform integrates Geo Connect for authentication, uses React with Next.js or Vite for front-end scaffolding, and introduces GRC20, the specification for structuring and publishing data to the decentralized knowledge layer called Geo. The demo walks through how developers can create public and private spaces, manage entities, and publish encrypted or public data using the Hypergraph framework. Kevin highlights the role of TypeSync, a tool that visually manages schema types and relationships within projects, and demonstrates the end-to-end process of authenticating, creating entities, syncing schemas, and publishing data. Example applications include DApp registries, governance platforms, and collaborative tools where users can maintain both private and public datasets. Ultimately, Hypergraph provides a full-stack, privacy-first framework for decentralized knowledge sharing, opening new pathways for structured, reusable, and encrypted blockchain data. 00:02 – Introduction & Overview of The Graph 00:47 – Decentralized Indexing & Data Access 01:12 – Token APIs, MCP Servers, and Substreams 02:16 – Hackathon Bounties & Categories 02:39 – Introduction to Hypergraph Framework 04:06 – Private Data & Local-First Encryption 05:16 – Full-Stack Setup with React, Vite, and Next.js 05:44 – Knowledge Graphs Explained (Entities, Relations, Spaces) 07:10 – Public vs Private Spaces in Hypergraph 08:02 – Sync Server & Geo Connect Architecture 08:55 – Code Example: Entities and Relations 10:19 – Publishing to Knowledge Graph (Public/Private Data) 10:40 – Example Use Cases: Crypto Projects, Governance, Registries 11:23 – Demo: Setting Up a Hypergraph Project 12:10 – Scaffolding with NPX & Framework Options 13:16 – Using TypeSync for Schema Management 15:16 – Creating Private & Public Spaces 17:29 – Exploring Knowledge Graph Data 18:05 – Managing Schema and Types in Code 19:43 – Updating and Syncing Entities 20:04 – Publishing Data to Sync Server and Knowledge Graph _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 🇮🇳 *ETHGlobal New Delhi* This workshop is specifically for ETHGlobal New Delhi, a 3-day hackathon held September 19-21 at the India International Convention & Expo Centre, 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!
