Celestia
Celestia is the first production modular data availability blockchain. It separates consensus and data availability from execution and settlement, letting rollups, sovereign chains, and other execution layers post their transaction data as blobs to Celestia under namespaces while running their own state machines. Light nodes use Data Availability Sampling and Namespaced Merkle Trees to verify availability without downloading full blocks, and the Blobstream / Blobstream X bridge attests Celestia data commitments on Ethereum and other EVM chains. The reference stack — celestia-app (consensus, Cosmos SDK + CometBFT) and celestia-node (DA bridge/full/ light nodes) — exposes a JSON-RPC API with nine modules (blob, header, share, state, das, fraud, p2p, node, da, blobstream), plus a modular DA interface used by Rollkit, Optimism Alt-DA, Arbitrum Nitro DAS, and other rollup frameworks.
Celestia publishes 10 APIs on the APIs.io network, including Node Blob API, Node Header API, Node DA API, and 7 more.
The Celestia catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.
Celestia’s developer surface includes authentication, developer portal, documentation, getting-started guide, engineering blog, tooling, code examples, and 27 more developer resources.
