If you're using The Graph Subgraphs today, nothing breaks with Horizon. Your APIs work exactly the same. Curation mechanisms unchanged. Query behavior identical. Zero developer action required. What you gain: Subgraphs now run on long-lived allocations, which means better uptime and fewer service interruptions. The infrastructure underneath got significantly more reliable while your code stayed exactly the same. The Graph is no longer just Subgraphs. You can now combine Subgraph data with Substreams for real-time processing, Token API for current balances, and analytics services, all through one protocol with unified payments. Multiple data services without multiple vendors. This matters for sustainability because centralized data providers have shut down, consolidated, or deprecated support with little warning over the past few years. The Graph's decentralized protocol with distributed service providers offers long-term continuity that centralized competitors can't match.(The Graph)
