Introducing Steel 1.0: A production-ready smart contract prover bringing boundless runtime to EVM apps.

Steel moves smart contract execution offchain, bypassing gas limits while preserving onchain security.

Enhance your existing Solidity contracts ↓
2/ Steel uses execution proofs to eliminate blockchain re-execution.

Any computation—no matter how complex—becomes a compact proof which is quickly verified onchain.

Result? Boundless runtime, massive cost reductions. Image
3/ Our partners are already leveraging Steel's power.

One app:
- Processed 400,000 SLOADs in a single contract call
- Saved 1.2 billion gas (equivalent to 30 blocks of execution)
- All proven with just one execution proof

This is not small improvement. It's a paradigm shift.Image
4/ EVM developers can:
→ Use existing EVM smart contract logic
→ Prove execution over historic onchain state
→ Optimize expensive onchain operations
→ Or build apps that were previously impossible due to gas constraints

All while preserving EVM compatibility and security.
5/ At RISC Zero, we envision a future where @boundless_xyz replaces the need for onchain execution.

Steel is helping make this vision a reality.

Introducing Boundless: The Verifiable Compute Layer

Unlimited execution. Global composability. On-demand scaling.

For every developer. On any chain.
2/ Boundless leverages ZK to enable verifiable off-chain execution for any chain.

This means any application can be built off-chain while inheriting blockchain security.

No block/txn/execution limits. Only boundless possibilities.Image
3/ Boundless will bring forth a new era of advanced & expressive apps:
→ DEXs with CEX-like UX, accessing the liquidity of all chains
→ Verifiable AI interactions with onchain results
→ ZK-wrappers for centralized IDs

Imagine it. Build it. Scale it with Boundless.

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. ⏫

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.
