Celestia is the first modular blockchain network dedicated solely to data availability — the foundational service that verifies that transaction data has been published and is available for inspection. Rather than executing transactions itself, Celestia enables other blockchains (rollups, L2s, sovereign chains) to use it as a data availability layer, allowing them to inherit Celestia's security for data publishing without paying for Ethereum's expensive calldata. TIA is used for paying blob fees and staking.
In modular blockchain design, execution, consensus, data availability, and settlement are separated into specialized layers. Celestia handles only consensus and data availability, using Data Availability Sampling (DAS) where light nodes can verify data availability by sampling random small chunks — without downloading the full block. This allows Celestia's throughput to scale with the number of light nodes, not validators. Rollups post their transaction data as 'blobs' to Celestia and receive a certificate proving the data is available. The sovereign rollup model allows chains built on Celestia to handle their own execution and settlement while outsourcing data availability to a shared, secure layer.
Posting rollup data to Ethereum mainnet (calldata) is expensive and creates a bottleneck as more rollups compete for block space. Celestia offers a dedicated, high-throughput, low-cost data availability layer purpose-built for rollups. This enables thousands of rollups to scale independently while sharing a common, secure data availability foundation — without competing for Ethereum's limited and expensive block space.
The first blockchain network dedicated entirely to data availability, using Data Availability Sampling so light nodes can verify data without downloading full blocks — enabling throughput that scales proportionally with the number of light nodes rather than being bounded by validator count.
Use multiple indicators together to build complex entry conditions for TIA.
Ethereum also provides data availability via EIP-4844 blobs but at higher cost; Celestia specializes in DA with lower fees and higher throughput
NEAR also offers data availability services; Celestia's entire design is DA-first while NEAR is a general L1 with DA as an additional service
