Core Devs Call #31

In Core Devs Call #31, StreamingFast presented Substreams Codegen, a toolset for easier development of Substreams-powered subgraphs with two integration methods and a contained development environment for local and cloud use. Graph Horizon (GIP-0066) was introduced as a modular protocol to extend The Graph’s functionality, detailing roles, staking, service registration, and payment flows. GIP-0068 introduced the Subgraph Service, which transitions subgraph indexing into Graph Horizon, enhancing stake management, allocation, query fees, and dispute resolution while ensuring backward compatibility with existing systems.
