Celestia

Celestia is a modular blockchain network whose base layer specializes in ordering transactions and making their data available, rather than executing them. Rollups, Layer 2s and app-chains publish transaction data to Celestia while running their own execution environments, virtual machines, fee tokens and execution rules. The core technical primitive is data availability sampling (DAS), which lets light nodes verify that block data has been published by downloading only a small portion of each block; because verification capacity grows with the number of light nodes, the network's data throughput is designed to scale as the light-node set grows. Celestia's mainnet beta went live in October 2023, described at the time as the first specialized modular consensus and data network.

The project is organized around two entities: the Celestia Foundation, which raises capital and supports the network, and Celestia Labs, the core engineering organization. As of the current website, Celestia positions itself as a full-stack partner that designs, builds and hands over custom high-throughput chains to enterprise customers, who then own the infrastructure, roadmap and economics. Two productized offerings are marketed: Fibre Blockspace, aimed at high-performance trading venues and payment rails, and Private Blockspace, which keeps positions, balances and order sizes private. The company targets use cases including agentic payments and onchain exchanges requiring millisecond latency.

Celestia's native token, TIA, is used to pay for blobspace (publishing data to the network) and for staking and governance. The core developer community has published a technical roadmap centered on scaling toward 1 gigabyte blocks; the more recent Celestia Fibre milestone targets up to 1 Tb/s of blockspace throughput, which the company equates to 625M+ transactions per second.

Founding story

Celestia was co-founded by Mustafa Al-Bassam, an Iraqi-British computer security researcher who completed a PhD at University College London in 2021 with a thesis on securely scaling blockchain base layers, and who previously co-founded Chainspace, a sharding-based smart contract platform acquired by Facebook in 2019.

Business model

Celestia sells blockspace on a shared data-availability network and, following the acquisition of Sovereign Labs, also acts as a custom blockchain development partner that designs and ships production-ready chains which the customer then owns and operates.

Network usage is paid for in the native TIA token, which is used to purchase blobspace for publishing data to Celestia, as well as for staking and governance. The website markets an economic model in which chain operators charge end users roughly $0.0001 per transaction.

Traction

The company website reports 25+ production chains built and launched by the team, over 20 chains running on Celestia, $8.5B+ settled in cross-chain transfers, 30K orders/second on perpetual futures exchanges and $26B+ in notional options and futures volume. At the time of the 2024 Foundation raise, developers had deployed the first 20 rollup chains and Celestia data blobs had recently exceeded half of total data published by rollups. Open-source repositories are actively maintained, with celestia-node at roughly 996 stars and celestia-app at 416 stars.

Latest developments

Celestia Labs acquired Sovereign Labs, announced via X, establishing Celestia Labs as a full-stack custom blockchain development partner spanning Layer 1 through execution and application layers. The company also announced Celestia Fibre, which it says brings up to 1 Tb/s of blockspace throughput, and now markets two offerings, Fibre Blockspace and Private Blockspace.
