+The `fault-mon` detects differences between the transaction results generated by your local Optimism node and the transaction results actually published to Ethereum.
 Currently, transaction results take the form of [the root of the Optimism state trie](https://medium.com/@eiki1212/ethereum-state-trie-architecture-explained-a30237009d4e).
 
 The state root of the block is published to the [`L2OutputOracle`](https://github.com/ethereum-optimism/optimism/blob/39b7262cc3ffd78cd314341b8512b2683c1d9af7/packages/contracts-bedrock/contracts/L1/L2OutputOracle.sol) contract on Ethereum.
