Modular blockchain project Celestia has introduced Blobstream to the Arbitrum ecosystem, allowing developers to create customizable chains (called Orbit) using Celestia for data availability.
Orbit Chains can be Layer 2 chains that settle directly on Ethereum, or as Layer 3 chains that can settle on Arbitrum’s own Layer 2: Arbitrum One.
Deploying Blobstream in this context allows L2 and L3 rollups to use Celestia light clients for data availability sampling (DAS) – a technique to ensure that data related to transactions and state changes is accessible to all network participants.
This integration will give Arbitrum’s Orbit chains the ability to publish data to Celestia alongside their existing setups, which may be more costly or too complex for many developers.
That’s why Blobstream wants to simplify the process for Arbitrum developers to leverage DAS and eliminate the need to create a data availability “committee” to launch their own chain. Previously, this requirement required an independent body data availability committee able to store data and deliver it on demand.
“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. “Blobstream allows developers to continue building the Ethereum ecosystem.”
Celestia developed Blobstream in collaboration with Succinct Labs. The solution will use Succinct Labs’ zero-knowledge light client to transfer attestations from Celestia’s data root to Orbit smart contracts.
Blobstream’s latest implementation follows its Edition in the Base ecosystem last week.
