# Fault proof VM: MIPS.sol

The `MIPS.sol` smart contract is an onchain implementation of a virtual machine (VM) that encompasses the MIPS32 R1 Instruction Set Architecture (ISA).
The `MIPS.sol` smart contract is an onchain implementation of a big-endian virtual machine (VM) that encompasses the MIPS32 R1 Instruction Set Architecture (ISA).
This smart contract is the counterpart to the off-chain MIPSEVM golang implementation of the same ISA. Together, the onchain and off-chain VM implementations make up [Cannon](cannon),
Optimism's Fault Proof Virtual Machine (FPVM). Cannon is a singular instance of a FPVM that can be used as part of the Dispute Game for Optimism's (and Base's) optimistic rollup L2 blockchain.
The Dispute Game itself is modular, allowing for any FPVM to be used in a dispute; however, Cannon is currently the only FPVM implemented and thus will be used in all disputes.

The `MIPS` contract provides an on-chain implementation of a big-endian MIPS32 R1 virtual machine,
designed to execute fault proofs for disputes by processing a standardized instruction set.
This enables instances of `FaultDisputeGame` and `PermissionedDisputeGame` to resolve disputes
over state transitions accurately and consistently.
