# regen rollback
rollback cosmos-sdk and tendermint state by one height
A state rollback is performed to recover from an incorrect application state transition, when Tendermint has persisted an incorrect app hash and is thus unable to make progress. Rollback overwrites a state at height n with the state at height n - 1. The application also rolls back to height n - 1. No blocks are removed, so upon restarting Tendermint the transactions in block n will be re-executed against the application.
