Celestia is a modular data-availability network that orders and publishes blobs while leaving application execution and settlement to layers built above it. TIA pays for blobspace, secures proof of stake and participates in governance. Blob transactions assign data to namespaces and commit it in erasure-coded blocks. Light nodes use data availability sampling to gain confidence that recent block data was published without downloading everything, while applications interpret and execute their own state. Use this page to distinguish data availability from execution and permanent storage, understand TIA fees, and plan namespace, node and archival requirements.<\/p>","protected":false},"excerpt":{"rendered":"
