Explore the data available on Stellar Mainnet, inspect its block model, then move into Substreams packages you can consume.
01
Block model
Block data foundation
Start from the registry block type and compose packages around the source model.
02
Protocol
Protocol activity streams
Build package pipelines around transactions, events, and account changes.
