The cannon (cannon cannon cannon) is an on chain interactive dispute engine implementing EVM-equivalent fault proofs.
It's half geth, half MIPS, and whole awesome.
- It's Go code
- ...that runs an EVM
- ...emulating a MIPS machine
- ...running compiled Go code
- ...that runs an EVM
For more information on Cannon's inner workings, check this overview.
contracts -- A MIPS emulator implementation, using merkleized state and a pre-image oracle.
example -- Example programs that can be run and proven with Cannon.
extra -- Extra scripts and legacy contracts, deprecated.
mipsevm -- Go tooling to test the onchain MIPS implementation, and generate proof data.
unicorn -- Sub-module, used by mipsevm for offchain MIPS emulation.
Pre-requisites: Go, Node.js, Make, and CMake.
make build
make test # verify everything works correctly
