Unlocking Blockchain Data with GraphQL

" summary

Explains how GraphQL plus The Graph turns chains into queryable stores by extracting on-chain events, mapping them into ETL into Postgres tables and exposing them via GraphQL. Describes a built wrapper called the graph client that enables client-side composition of federation-compliant subgraphs, and mentions Graph Mesh and an announced Gateway. Demonstrates live query support using live queries (polling), shows the replication problem with nodes indexed to different heights (e.g., 980 vs 990), and argues these tools solve latency and composability in practice.
