# Building Solana data flows: Using n8n to automate block height extraction through GetBlock’s RPC infrastructure

The Solana ecosystem moves incredibly fast. With block times sitting around 400 milliseconds, anyone building automated workflows, indexing tools, or real-time analytics dashboards runs into one major challenge: RPC reliability and latency . If you depend on overloaded public endpoints, your automation is always one delay away from breaking. When a pipeline starts lagging or drops requests, the whole workflow can fall apart. In this breakdown, I’ll show how to build a more reliable data extracti
