According to Foresight News, zero-knowledge proof software developer RISC Zero is working with Celestia to build a zkVM-based Blobstream cross-chain bridge "Blobstream Zero". Blobstream Zero will allow Rollups and application ZK to prove and verify the validity of Celestia's data availability (DA) on any chain by connecting Celestia's modular data availability layer with Ethereum, Optimism, Bitcoin, Solana, etc.
Blobstream Zero will perform on-chain verification on all major chains, starting with Ethereum and gradually expanding to Optimism, Arbitrum, Solana, and Bitcoin, with more to come in the coming months. Blobstream Zero will also allow applications to combine their execution of ZK proofs with recursive DA light client proofs and inclusion proofs to optimize existing and new use cases.
