## Description

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.
