Achieving sub-second latency on networks such as Base, BSC, and Solana is now possible through Substreams. By utilizing composable modules and parallel processing, this technology successfully overcomes the traditional bottlenecks associated with sequential blockchain indexing at a large scale.

An exciting evolution is also planned for 2026, when Substreams will transition The Graph Network into a completely permissionless data service. To guarantee overall data integrity, this upcoming shift will deploy a probabilistic verifier, while simultaneously introducing a Provider Selection Oracle and enabling trust-minimized payments.
