Celestia launches Blobstream on Base

Celestia has launched Blobstream on the Base mainnet, allowing developers to deploy Base L3 chains to access Celestia's data availability. Blobstream is a one-way data validation bridge that can stream Celestia's DA layer to other chains. Developers can access efficient block space at prices unrelated to Gas fees on the underlying chain. This implementation allows L2 and L3 rollups to use Celestia's light client for data availability sampling.

Blobstream uses Zero-Knowledge Proofs to verify the validity of Celestia's block headers for confirmation on the target EVM chain. Blobstream is currently in the experimental stage and plans to support other chains.
