Developed by Succinct Labs, Blobstream enables Celestia’s data roots to be streamed to an Ethereum light client on-chain. The solution offers high-throughput data availability (DA) for Ethereum layer 2 solutions (L2s), secured by cryptoeconomic guarantees. Apart from the launch, the Celestia team announced that Blobstream on the Ethereum mainnet is now accessible on Celestia’s blockchain explorer Celenium.
According to Celestia’s blog announcement, Succinct Labs has introduced Blobstream X, a zero-knowledge (ZK) implementation that streamlines the verification of Celestia validator signatures on-chain with a single ZK proof. This reduces validator overhead, simplifies the Celestia protocol, and accelerates the streaming of data root commitments for Ethereum L2s.
As noted, both Blobstream and its ZK implementation are currently available on testnet. Following code audits and Celestia’s upcoming 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 brought Blobstream to Arbitrum Orbit, Starknet, and Base, marking a continuous commitment to improving the Ethereum ecosystem’s infrastructure.
