  - First production modular data availability layer; separates consensus + DA from execution and settlement
  - Mainnet Beta launched October 2023; chain id celestia
  - Mocha-4 public testnet and Arabica devnet for application developers
  - PayForBlobs (MsgPayForBlobs) transactions for publishing namespaced blob data
  - Namespaced Merkle Trees (NMT) so each rollup only downloads data for its namespace
  - 2D Reed-Solomon erasure coding over the extended data square (EDS)
  - Data Availability Sampling (DAS) lets light nodes verify availability without downloading full blocks
  - Bridge, full, and light celestia-node modes
  - JSON-RPC over HTTP (default :26658) with bearer-token auth and four permission scopes (public, read, write, admin)
  - WebSocket subscriptions for blob.Subscribe, header.Subscribe, fraud.Subscribe
  - Modular DA interface (da.*) compatible with Rollkit, Optimism Alt-DA, Arbitrum Nitro DAS, OP-Succinct, Kona, Hana
  - celestia-app exposes Cosmos SDK gRPC (:9090), REST (:1317), and CometBFT RPC (:26657) for consensus-level queries
  - Blobstream and Blobstream X bridge to Ethereum and EVM chains for cross-chain data root verification
  - Lumina Rust+Wasm light node runs in the browser
  - Funded by TIA staking and PayForBlobs gas fees; no central API key or commercial pricing tier
  - Reference implementations in Go (celestia-node, celestia-app) and Rust (lumina, celestia-rpc)
  - Apache-2.0 licensed across the celestia-node, celestia-app, celestia-core, and tooling repos

description: '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.
