We're thrilled to announce a collaboration with @celestiaorg to build Blobstream Zero, a new-generation zkVM-based Blobstream bridge. 🟡

Blobstream Zero will bridge Celestia's permissionless DA layer to Ethereum, Optimism, Bitcoin, Solana, and more...
2/ Blobstream Zero opens up a new class of modular apps: ZK Coprocessors.

Dapps on Ethereum, Optimism, and Solana can run highly functional and data-rich ZK programs, powered by RISC Zero and Celestia, while maintaining composability.
3/ As a fully open-sourced and permissionless public good, any developer and project can run Blobstream Zero and generate ZK proofs locally.

The Rust-based repo will be easily upgradable and extensible, allowing projects to modify the bridge to fit their needs. ⏫
4/ This implementation will strengthen the security of Celestia DA bridges by enabling applications to choose which bridge best fit their security requirements.🔒

We're excited to build this groundbreaking tech alongside Celestia and empower the modular ecosystem.💛

Introducing zkVM 1.0: The Future of Verifiable Computation🌐

Today, we're excited to launch the world's first and most performant, production-ready zkVM.

zkVM 1.0 makes zero-knowledge proofs scalable, accessible, and cost-effective for any chain.
2/ Unrivaled Performance 🔥

zkVM 1.0 offers cost-effective proving with performance that significantly outperforms competitors.

Our tests show zkVM 1.0 is significantly less expensive and consistently faster across various workloads.

Full details ↓

3/ Benchmark Highlights ⏫

Across the board, a properly configured RISC Zero zkVM outperforms a similarly configured SP1 deployment in both cost and speed. This holds true:

→ In the cloud
→On consumer Macs (M2 Max and M3 Max)
→On consumer PCs with NVIDIA GPUImage

Introducing Steel: our Alloy-based view call proof library designed to revolutionize dapp scalability directly on Ethereum L1 and beyond. 🟡

Why Steel is a game-changer for EVM developers and onchain protocols ↓
With Steel, RISC Zero’s ZK Coprocessor gains access to Ethereum's full state.

Tests surpassing 100K SLOADs (>210M gas) show Steel can cut $1000s in fees with one proof.

Steel enables Layer 0.5 scaling, sidestepping Ethereum's block & txn size limits, unlocking new use cases.
Steel enhances RISC Zero’s ZK Coprocessor, offering:

✅ Solidity smart contract execution
✅ Unbounded compute via Continuations
✅ Trustless off-chain execution
✅ Security of the first production-ready zkVM
✅ No vendor lock-in

All without writing a single circuit.

Introducing Zeth: A Fully Open Source Type 0 zkEVM 🚀

Built on the RISC Zero zkVM and Bonsai, Zeth is a performant, upgradable, and scalable way for developers to ZK prove any Ethereum block ushering in the next generation of ZK and EVM

🧵 1/8 Learn More Below!
Democratizing zkEVM 🧑‍💻

Zeth makes it easier to build ZK rollups, zkEVMs, light clients, and bridges by providing an open source solution to generate ZK Proofs of EVM and Ethereum blocks

Projects can use Zeth to bring ZK to their protocols in weeks instead of years

🧵 2/8
Why is Zeth a Type 0 zkEVM?

Zeth can prove all aspects of Ethereum, from every EVM opcode and EIPs to the block construction itself

We're able to accomplish this because Zeth was built by reusing major parts of reth and revm on top of the RISC Zero zkVM

Next generation Optimistic Rollups are here! 🚀

@RiscZero and @LayerN_ have joined forces to develop the first ZK Fraud Proof system, combining Optimistic Rollups with ZK Proofs, opening the door for more performant, reliable, and secure Blockchains.

🧵 [1/6]
Optimistic Rollups and Zero Knowledge Proofs don’t need to fight! ❤️

While @LayerN_ is a modular Optimistic Rollup, its Fraud Proof system has been completely overhauled and replaced with Succinct ZK Proofs, which attest to invalid state transitions.

[2/6]
This was accomplished by porting the @LayerN_ execution environment onto the @RiscZero zkVM.

🎉 This is just the start! 🎉

The versatility of the @RiscZero zkVM will enable compatibility with other execution layers in the future such as EVM, SVM, and WASM etc.

A huge thank you to participants in @__zkhack__ 's first IRL hackathon! Take a look here at the winning projects (and learn more about what we're looking for at hackathons): risczero.com/blog/zkhack
Thank you to everyone who participated and submitted to the RISC Zero prize category! Here are some of the projects that we loved:
The ZeroSkill team added a Rust-based Brainf*ck interpreter to the guest zkVM and used it to capture the execution of an interpreted program. This project was a great demonstration of ZK proofs for interpretable code.

This week’s RISC Zero Study Club is focused on FRI!

For real-time FRI learning, join us Wednesday 10am PST/5PM UTC at zoom.us/j/99200763534

If you'll be at #ZKSummit, you can also catch @Paul_Gafni's workshop on this topic.

For async learning, read on!

The FRI protocol, first published in 2018, is the backbone 🦴of all implementations of STARKs – and some newer SNARKs.
