RISC Zero and Celestia collaborate to build zkVM-based Blobstream bridge Blobstream Zero

Blockchain infrastructure provider RISC Zero and Celestia are collaborating to build Blobstream Zero, a zkVM-based Blobstream bridge. Blobstream Zero aims to connect Celestia’s data availability layer with chains such as Ethereum, Optimism, Bitcoin, Solana, and more. Blobstream is Celestia’s solution that enables Rollups to leverage Celestia light clients for data availability sampling. Blobstream Zero introduces the ability to verify Celestia DAs using zero-knowledge proofs. The integration allows Rollups and applications to generate proofs more efficiently across chains. Blobstream Zero also introduces a ZK coprocessor that enables DApps on Ethereum, Optimism, and Solana to run data-intensive ZK programs without sacrificing composability. Blobstream Zero will be a fully open source and permissionless public product. This means that all developers and projects can run Blobstream Zero and generate ZK proofs locally.
