Celestia-node is the Go implementation of Celestia’s data availability (DA) node types: **bridge**, **full**, and **light**. The DA network wraps celestia-core by consuming or producing ExtendedHeaders and making block data available via share sampling (DAS). Use this skill to operate nodes, query headers/shares/state, submit PayForBlob and other transactions, and reason about P2P discovery and fraud proofs.
