Celestia Labs

Celestia Labs was founded by Mustafa Al-Bassam, Ismail Khoffi, John Adler, and Nick White to build the first modular blockchain, separating consensus and data availability from execution. Celestia provides a dedicated data-availability layer: rollups and app-chains post their transaction data to Celestia, which uses data-availability sampling and erasure coding so light nodes can verify that data is published without downloading all of it, enabling cheaper, more scalable blockspace. The Celestia mainnet launched in late 2023; the July 2025 Lotus upgrade cut TIA inflation by 33% and added Hyperlane-based interoperability. Eclipse has become the dominant consumer of Celestia blobspace, accounting for roughly 84% of blob volume. The project raised a $55 million round in 2022 co-led by Bain Capital Crypto and Polychain Capital, and the Celestia Foundation later announced an additional $100 million raise.
