Celestia Price (TIA)

A rollup needs to make enough transaction data available for others to reconstruct what happened. Celestia lets rollups publish that data in blobs. A rollup can send its data to Celestia while running transactions and handling settlement elsewhere.

Light nodes can sample small pieces of block data to check whether the full data was made available. This does not prove that a rollup executed its transactions correctly. The rollup has its own rules for checking results.

TIA pays for publishing data to Celestia and can be staked to help secure the network. A rollup posting blobs pays for the space it needs. The TIA price chart gives the market quote for the token used to pay those fees.
