**Cannon has moved to the [Optimism monorepo](https://github.com/ethereum-optimism/optimism/tree/develop/cannon)!**

This repository is an archive of the following Cannon versions:

- [`v0.1.0`](https://github.com/ethereum-optimism/cannon/tree/v0.1.0): the original Cannon, implemented by `geohot`.

- [`v0.2.0`](https://github.com/ethereum-optimism/cannon/tree/v0.2.0): improved Cannon, with bugfixes and experimental demos.

- [`v0.3.0`](https://github.com/ethereum-optimism/cannon/tree/v0.3.0): refactored proof-format, initial Optimism Bedrock support.

## About

Cannon *(cannon cannon cannon)* is an onchain MIPS instruction emulator.

Cannon supports EVM-equivalent fault proofs by enabling Geth to run onchain,

one instruction at a time, as part of an interactive dispute game.

* It's Go code

* ...that runs an EVM

* ...emulating a MIPS machine

* ...running compiled Go code

* ...that runs an EVM
