What is Celestia? [Celestia](https://coinstats.app/coins/celestia) is a modular blockchain that specializes in consensus and data availability rather than executing every application transaction. Its native token is TIA, used to pay for published data, secure the network through staking, participate in governance, and serve as gas or currency for chains built with Celestia. ## How Celestia’s technology works Celestia separates four blockchain functions: execution, settlement, consensus and data availability. Rollups and application-specific chains execute transactions according to their own rules, while Celestia orders and publishes the underlying data so users can verify that it is available. Its main technology is data availability sampling, or DAS. Light nodes sample small parts of erasure-coded blocks instead of downloading entire blocks. Celestia uses two-dimensional Reed-Solomon encoding to add redundancy, allowing sampling to provide evidence that the complete data can be recovered. Namespaced Merkle trees organize data by application, enabling a rollup to retrieve and prove only the data associated with its namespace. Rollups publish data through PayForBlobs transactions and pay fees in TIA. Rollkit provides a framework for building modular rollups, while Blobstream was designed to relay Celestia data commitments to Ethereum. Celestia’s documentation classifies Blobstream as legacy, and Succinct-operated SP1 Blobstream deployments have not received new commitments since September 2026. ## Use cases and ecosystem The primary use case is data availability for rollups. A rollup can use Celestia to publish transaction data while maintaining a separate execution environment and settlement network. The same model supports sovereign chains and application-specific networks for gaming, payments, trading and other specialized applications. Celestia has integrated with Arbitrum Orbit and Nitro, allowing Orbit developers to select Celestia as a data availability provider. It has also announced support for Polygon’s Chain Development Kit. The ecosystem includes projects such as Eclipse and Manta, while Rollkit supplies development tooling for modular rollups. ## Who is behind Celestia and where is it based? The project began in 2019 under the name LazyLedger and was renamed Celestia on 15 June 2021. Celestia Mainnet Beta launched on 31 October 2023. The founders are Mustafa Al-Bassam, Ismail Khoffi and John Adler. Nick White is identified in Celestia’s public materials as an early executive and developer, while current leadership materials identify him as co-founder and CEO of Celestia Labs and Preston Evans as CTO. Celestia Labs is the development organization associated with the network. The Celestia Foundation is a nonprofit based in Liechtenstein and operates under Liechtenstein law. Public company information identifies Strange Loop Labs AG, also associated with Celestia Labs, in Vaduz, Liechtenstein. Celestia’s public history includes a $1.5 million seed round in 2021 and a $55 million Series A and Series B financing round in 2022. ## Tokenomics and market data The CoinStats snapshot captured on 1 October 2026 records a price of $0.439, a 24-hour change of -1.11%, a market cap of $428.37M (rank #174), and 24-hour volume of $61.43M. Circulating supply is 975,470,038 TIA, while total supply is 1,178,391,932 TIA. The all-time high is $20.85, the current price is 97.89% below it. The documented genesis supply was 1,000,000,000 TIA. Its distribution included 7.41% for the public allocation, 12.59% for future initiatives, 26.79% for research and development and the ecosystem, 19.67% for early Series A and B backers, 15.90% for seed backers, and 17.64% for initial core contributors. Vesting schedules differ by allocation, and locked tokens can still be staked. [TIA](https://coinstats.app/coins/celestia) has ongoing issuance rather than a fixed maximum supply. The original inflation schedule began at 8% annually and declined toward a 1.5% floor. The Lotus upgrade reduced inflation to approximately 5.0% in July 2025, while the Matcha upgrade reduced it to approximately 2.5% in November 2025. The revised schedule continues declining by 6.7% annually until reaching the 1.5% floor. Two percent of block rewards goes to the community pool. ## Consensus and security [Celestia](https://coinstats.app/coins/celestia) uses proof of stake with the Cosmos SDK and CometBFT consensus. Validators stake or receive delegated TIA, produce blocks and vote on data ordering. Misconduct can result in penalties, while staking rewards compensate participants for helping secure consensus. Data availability security comes from erasure coding, DAS and light-node participation. This security model does not execute or validate every rollup transaction. The complete security of an application also depends on its execution, settlement and proof systems. ## Competition and development roadmap Celestia competes with Avail, EigenDA, NEAR DA and Ethereum blob data. Its distinct proposition is a dedicated proof-of-stake data availability layer combining DAS, namespaced Merkle trees and customizable execution environments. The trade-off is that applications rely on several separate components rather than one chain providing every function. Recent development has focused on higher throughput and specialized application infrastructure. Ginger doubled data availability throughput, Lotus changed the inflation schedule, and Matcha targeted blocks of up to 128 MB. In January 2026, Fibre Blockspace was introduced with a reported target of 1 Tb/s of blockspace across 500 nodes. Other 2026 initiatives included Private Blockspace, the Hibiscus upgrade for cross-chain messaging and the acquisition of Sovereign Labs to expand custom blockchain development. **Sources:** - [Celestia Documentation: Data availability](https://docs.celestia.org/learn/celestia-101/data-availability) - [Celestia Documentation: Staking, governance, & supply](https://docs.celestia.org/learn/TIA/staking-governance-supply) - [Celestia Documentation: Overview of TIA](https://docs.celestia.org/learn/TIA/overview) - [Celestia Documentation: Blobstream](https://docs.celestia.org/learn/blobstream) - [Celestia Foundation](https://blog.celestia.org/the-celestia-foundation) - [Introducing Fibre: 1Tb/s of blockspace](https://blog.celestia.org/introducing-fibre-1tb-s-of-blockspace/) - [Celestia Labs Acquires Sovereign Labs](https://blog.celestia.org/celestia-labs-acquires-sovereign-labs-to-build-high-performance-custom-blockchains) --- ## More on Celestia - [Is Celestia (TIA) a good investment?](https://coinstats.app/ai/a/investment-analysis-celestia) - [What are the key Celestia (TIA) support and resistance levels today?](https://coinstats.app/ai/a/latest-news-for-celestia) --- ## Related Questions - What happens to TIA inflation after it reaches the 1.5% floor? - How does Celestia's data availability sampling compare to EigenDA's security model? - What are the key differences between Celestia and Avail for rollup developers? --- ## Related Coins ### Solana (SOL) - What is the Solana (SOL) price prediction for 2026-2030? - What is the latest Solana (SOL) news today? - Why is Solana (SOL) price down today? - What is the Solana (SOL) market sentiment today? - What are the key Solana (SOL) support and resistance levels today? - Is Solana (SOL) a good investment? - What is Solana (SOL) crypto? ### Ethereum (ETH) - What is the Ethereum (ETH) price prediction for 2026-2030? - What is the latest Ethereum (ETH) news today? - Why is Ethereum (ETH) price up today? - What is the Ethereum (ETH) market sentiment today? - What are the key Ethereum (ETH) support and resistance levels today? - Is Ethereum (ETH) a good investment? - What is Ethereum (ETH) crypto? --- *This article was generated by [CoinStats AI](https://coinstats.app/ai)*
