# Kakarot

> We are building a ZK proving engine for the EVM , radically changing digital data verification.

Kakarot implements a ZK proving engine for the Ethereum Virtual Machine enabling trust-minimized, scalable state verification using STARK technology.

Kakarot provides zero-knowledge proving infrastructure for EVM-compatible blockchains, allowing any chain to transition to ZK for improved security and scalability. Built on CairoVM, it implements provable EVM execution that works across Ethereum L1, rollups, and Bitcoin sidechains. The system generates ZK proofs of block execution, enabling efficient state verification and cross-chain interoperability.

## Products

- [Keth](https://thegrid.id/profiles/kakarot): Keth implements chain-agnostic EVM proving that generates ZK proofs of EVM block execution in real-time. The system can help optimistic rollups transition to ZK, reinforce existing ZK-rollups with multiple proof systems, and power ZK-bridges for cross-chain interoperability, all while leveraging Starkware's STARK technology for efficient proof generation. (Developer Tooling, In Development)
- [Kakarot on Bitcoin](https://thegrid.id/profiles/kakarot): Kakarot on Bitcoin enables Ethereum-compatible ZK-rollups secured by Bitcoin using OP_CAT and other opcodes. It allows the verification of ZK proofs directly on Bitcoin, enabling trust-minimized bridging of BTC to rollups and unlocking native DeFi capabilities while maintaining Bitcoin's security guarantees. (Developer Tooling, In Development)
- [Kakarot zkEVM](https://thegrid.id/profiles/kakarot): Kakarot implements a complete EVM in Cairo, enabling existing Solidity smart contracts to run on Starknet. The system combines STARK-based cryptography with full EVM compatibility, allowing developers to deploy and execute Ethereum applications within Starknet's high-performance environment while maintaining code compatibility.
