The Celestia team announced via X on Wednesday that Celestia Labs has acquired Sovereign Labs.
This acquisition establishes Celestia Labs as a full-stack custom blockchain development partner for companies building onchain, marking a new chapter for our go-to-market strategy and ambitions.
With Sovereign, Celestia’s expertise now spans the entire blockchain stack from Layer 1 to the execution and application layers, enabling end-to-end development for peak scale, performance, and customisation.
Celestia is an L1 blockchain purpose-built for data availability - the scalability foundation for all commerce to come onchain. Rollups, app-chains, and Layer 2s plug into Celestia to order and publish transaction data, while running their own execution environments independently.
At the core of Celestia is data availability sampling (DAS): a cryptographic technique that lets light nodes verify data availability without downloading the full block. This means Celestia's security scales with the number of light nodes - not just validators - making it uniquely suited for a world of millions of onchain applications.
Celestia's latest milestone is Celestia Fibre, which brings up to 1 Tb/s of blockspace throughput - enough to support hundreds of millions of onchain transactions per second. This positions Celestia not just as a research-grade DA layer, but as production-grade internet-scale infrastructure for the onchain economy.
Celestia focuses exclusively on ordering and making data available, and does that job at a scale no other DA layer can match. By using Celestia, rollups and app-chains gain:
-
Instant sovereignty - deploy a chain with your own VM, execution rules, and fee token, inheriting Celestia's security from day one
-
Massive scalability - blockspace throughput that grows as the network grows, not bottlenecked by monolithic consensus
-
Censorship resistance - data availability sampling ensures that even with a small number of light nodes, liveness and data integrity are preserved
The native token, TIA, is used for paying for blobspace (publishing data to Celestia) and for staking and governance within the network.
TIA is down 1.4% in the last 24 hours and now trades at $0.4036 per coin.
