What it is
Celestia is the first modular data-availability blockchain: it orders and publishes transaction data (via 'blobs') for rollups and other chains but does not execute transactions itself, letting anyone launch a sovereign blockchain on top of its DA layer.
Technology & consensus
Light nodes verify data availability through data-availability sampling (DAS) — randomly sampling small erasure-coded fragments of 2D Reed-Solomon-extended blocks secured by namespaced Merkle trees — so large blocks can be verified without downloading everything. Consensus is CometBFT/Tendermint proof-of-stake via the Cosmos SDK, and Blobstream relays DA attestations to Ethereum.
Token utility
TIA pays for blobspace (PayForBlobs transactions), is staked and delegated to secure the validator set and earn rewards, can serve as a gas token for new rollups to bootstrap without issuing their own token, and grants governance voting rights over network parameters and a community pool funded by 2% of block rewards.
Key risks & notes
No official token whitepaper could be fetched during this run; the project's original design document is the LazyLedger academic paper (linked from Celestia's own GitHub). Risks: unproven long-term demand for paid blobspace versus Ethereum blobs and EigenDA, large early-investor unlocks pressuring supply, and uncertain value accrual if rollups treat Celestia as a cheap commodity layer.
