Celestia, a modular blockchain network, has rolled out its data availability solution, Blobstream, on the Ethereum mainnet, as announced by the team on Monday.

Developed by Succinct Labs, Blobstream allows Celestia's data roots to be streamed to an Ethereum light client on-chain, offering high-throughput data availability (DA) for Ethereum layer 2 solutions (L2s), backed by cryptoeconomic guarantees.

Previously, Ethereum developers encountered throughput limitations, leading them to explore alternative layer 1 networks or rely on centralized services for DA.

Blobstream empowers developers to continue their work within the Ethereum ecosystem, enabling them to create customizable, high-throughput blockspace without requiring permissions or committees, while ensuring security through cryptographic economic guarantees.

In addition to the launch, Celestia announced that Blobstream on the Ethereum mainnet is now accessible through Celestia's blockchain explorer, Celenium.

According to Celestia's blog post, Succinct Labs has introduced Blobstream X, a zero-knowledge (ZK) implementation that simplifies the verification of Celestia validator signatures on-chain with a single ZK proof. This reduces validator overhead, streamlines the Celestia protocol, and expedites the streaming of data root commitments for Ethereum L2s.

Both Blobstream and its ZK implementation are currently available on the testnet. Following code audits and Celestia's imminent launch, the community will be able to deploy Blobstream on Ethereum Mainnet and L2s to enhance streaming DA.

Prior to this deployment, Celestia had already introduced Blobstream to Arbitrum Orbit, Starknet, and Base, demonstrating its ongoing dedication to improving the infrastructure of the Ethereum ecosystem.
