Powering the Modular Expansion with Blobstream Zero
Steven Li
The TL;DR:
RISC Zero and Celestia are collaborating to build Blobstream Zero, a next-generation zkVM-based Blobstream bridge.
Blobstream Zero will open up a world of possibilities for the modular ecosystem by bridging Celestia’s modular data availability layer to Ethereum, Optimism, Bitcoin, Solana, and more.
With this bridge, rollups and applications can ZK prove and verify the validity of Celestia’s data availability (DA) on any chain; cheaper and faster than ever before.
It also opens up a completely new class of modular applications: ZK Coprocessors. This means that dApps on Ethereum, Optimism, and Solana can run highly functional and data-rich ZK programs, powered by RISC Zero and Celestia while maintaining composability with the chain.
Blobstream Zero will be a fully open-sourced and permissionless public good.
The Rust-based repo will also be easily upgradable and extensible thanks to the zkVM foundations allowing projects to modify the bridge around their needs.
In collaboration with Celestia, we’re excited to announce our commitment to build Blobstream Zero, a next-generation zkVM-based Blobstream bridge.
Blobstream Zero will open up a world of possibilities for the modular ecosystem by bridging Celestia’s modular DA layer to Ethereum, Optimism, Bitcoin, Solana, and more. With this bridge, rollups and applications can ZK prove and verify the validity of Celestia’s data availability (DA) on any chain.
Blobstream Zero will inherit many powerful features from its zkVM-based foundations and will have on-chain verification across all major chains, starting with Ethereum and moving towards Optimism, Arbitrum, Solana, and Bitcoin with more coming over the next few months. Subsequently, Blobstream Zero ZK proofs will natively connect Celestia and the entire modular ecosystem to Web3.
The recursive composability of the RISC Zero zkVM not only enables Celestia to seamlessly integrate into existing zkVM-based modular blockchains such as Optimism, Eclipse, Sovereign Labs, Citrea, and others. It also opens up a completely new class of modular applications: ZK Coprocessors.
ZK Coprocessors scale the functionality and performance of dApps, across every chain, by offloading execution using ZK. With Blobstream Zero, ZK Coprocessors can now scale both the compute of a chain and the DA. Blobstream Zero will allow applications to compose their execution ZK proofs with recursive DA light client proofs and proofs of inclusion to optimize existing and new use cases. This means that dApps on Ethereum, Optimism, and Solana can run highly functional and data-rich ZK programs, powered by RISC Zero and Celestia while maintaining composability on-chain.
Blobstream Zero will be a fully open-sourced and permissionless public good. This means any developer and project can run Blobstream Zero and generate ZK proofs locally. The Rust-based repo will also be easily upgradable and extensible thanks to the zkVM foundations allowing projects to modify the bridge around their needs. This implementation will also strengthen the security of Celestia DA bridges by enabling applications to choose which bridge(s) fit their security needs.
Blobstream Zero is ushering in the next generation of Modular Expansion. One that expands far beyond Ethereum Rollups into new chains and new applications empowering developers to build whatever.
