# I Run Infrastructure

SatoshiNet needs infrastructure teams to run Core Nodes, indexers, explorers, RPC, monitoring, and data services.

Infrastructure is not peripheral. Indexers and nodes determine whether users can verify asset facts, transaction state, contract state, and cross-layer evidence.
