Celestia, the pioneering modular blockchain network, this week announced the deployment of its data availability solution, Blobstream, on Arbitrum Orbit. This move enables Layer 2 (L2) and Layer 3 (L3) networks built on the Arbitrum platform to leverage Blobstream for improved scalability and cost-effective operations.

Developed by Celestia in collaboration with Succinct, Blobstream uses zero-knowledge proof to efficiently authenticate blockchain information. This new approach is poised to address the data availability challenges that many builders face when developing products on Ethereum. These challenges often lead to higher costs or the need to migrate to alternative layer 1 networks.
“Before Celestia, throughput limitations forced developers building expressive onchain applications to migrate to alt-L1s or required the overhead of recruiting a committee to deploy their own chain,” Celestia said in a post on X.
According to Celestia, L2 and L3 networks using Arbitrum Orbit can now use Celestia’s light client for data availability sampling (DAS). This method enables the validation of blockchain data availability without the need to download the entire dataset, thus reducing storage costs and transaction fees.
Celestia claimed that the new approach also eliminates the need for projects to form a data availability committee, which was previously required to store and deliver transaction data on demand.
Prior to this deployment, Celestia had already introduced Blobstream to two of Ethereum’s other major L2 networks, Starknet and Base, marking a consistent effort to improve infrastructure across the Ethereum ecosystem.
