Risc Zero

Provides zero-knowledge proof tooling for Web3

Overview

RISC Zero builds infrastructure for Web3 developers to create and use zero-knowledge proofs. Its core tools are zkVM, a verifiable computer that runs code like a RISC-V processor to produce ZK proofs, and Bonsai, a decentralized proving engine that distributes proof generation across a network. By running user programs and generating succinct proofs verifiable on-chain, the platform enables privacy-preserving and scalable smart contracts and dApps. The goal is to become the primary Web3 infrastructure for ZK tooling, making it easier for developers to secure and scale decentralized applications.

Simplify's Take

What believers are saying

  • ZK-rollup TVL surges in 2025-2026 boost zkVM demand.
  • Bonsai optimizations slash proof times from hours to minutes.
  • Rust/C++ support expands developer adoption beyond crypto experts.

What critics are saying

  • Succinct Labs' SP1 erodes market with 10x faster proofs.
  • StarkWare's Stwo commoditizes Zeth in 3-6 months.
  • Polygon AggLayer bypasses Bonsai using Plonky3 proofs.

What makes Risc Zero unique

  • zkVM emulates RISC-V microprocessor for familiar coding in ZK proofs.
  • Bonsai decentralized engine proves Ethereum blocks in minutes.
  • Zeth introduces Type 0 zkEVM for fully Ethereum-compatible scaling.

How Zero-Knowledge (Zk) Tech Will Power The Future Of Crypto

The past year has witnessed the ascendancy of Zero-Knowledge (ZK) technology. From its potential to increase and secure privacy protocols in the Web3 space, to its increased efficiency in validating transactions, the implementation of the tech is further cementing the growth and integration of blockchain into our daily lives. Its role in increasing efficiency has been taking center stage, as zk-proofs allow for data batching in transactions, lowering the computational requirements to process the information and the amount of data stored on blockchain networks.This means introducing a trustless scalability mechanism which the industry has been sorely lacking. The additional component that has secured its place as the new widely accepted validation protocol is the inherent capability to process this data without the need for any unnecessary information being added in, reinforcing the privacy frameworks inherent to blockchain.To mark the commitment and the recognition of this potential, Ethereum and other Layer 1 platforms, the pillars of the industry, are in the process of transitioning towards settlement and proof verification through the implementation of ZK technology. As Layer 1s integrate this technology, we are about to see an industry-wide standardization. By securing the Web3 space with stronger validations, an issue in desperate need of resolution, this shift has the potential to secure the industry’s foundations and pave the way for the broad-scale adoption it has been lacking.Decentralization: a benefit and a hurdleZK technology has taken on the role of overcoming decentralization challenges, namely the creation of centralized verification hubs in current solutions, and the need for efficient systems to allow people easy access to additional chains.As the Web3 space develops, the focus is on the broader narrative of decentralized systems, keeping them so, and emphasizing the need for interoperability in an app-sharded future

Risc Zero'S Open Source Zeth Proves Ethereum Blocks In Minutes, Instead Of Hours

Introducing Zeth —The First Type 0 zkEVMSEATTLE, Aug. 22, 2023 /PRNewswire/ -- RISC Zero , developers of leading general purpose zero-knowledge (ZK) virtual machine technology, today announced Zeth , a first-of-its-kind "Type 0" (fully Ethereum-compatible) zkEVM built on the RISC Zero zkVM and Bonsai proving service . Zeth is a new way of architecting L2's and scaling Ethereum, making this milestone release a significant step forward for ZK tech and the Ethereum ecosystem. Zeth paves the way for unprecedented ease in building powerful and efficient ZK infrastructure such as ZK rollups, ZK light clients, and ZK bridges.Type 0: A new category of zkEVMIntroducing Zeth —The First Type 0 zkEVM Tweet thisEthereum was not originally designed around ZK-friendliness, so there are many parts of the protocol that take a large amount of computation to ZK-prove. Type 1 aims to replicate Ethereum exactly, and so it has no way of mitigating these inefficiencies. At present, proofs for Ethereum blocks take many hours to produce
