# BfcOffences

### Description

The Bifrost Node tracks offences of validators and penalizes them to maintain network stability. The related implementation is defined in the `pallet_bfc_offences` module which is a central module implemented to handle offences reported through multiple modules and is responsible for counting offences and processing validator slashing.

### Extrinsics

**set\_offence\_expiration(new: `SessionIndex`)**

* interface: `api.tx.bfcOffences.setOffenceExpiration`
* summary: Sets a new offence expiration for all validators. It must be specified in sessions. The origin should be the root.

**set\_max\_offence\_count(new: `OffenceCount`)**

* interface: `api.tx.bfcOffences.setMaxOffenceCount`
* summary: Sets a new maximum offence count for all validators. The origin should be the root.

**set\_offence\_activation(is\_active: `bool`)**

* interface: `api.tx.bfcOffences.setOffenceActivation`
* summary: Sets the activation of validator offence management. The origin should be the root.

**set\_slash\_activation(is\_active: `bool`)**

* interface: `api.tx.bfcOffences.setOffenceActivation`
* summary: Sets the activation of validator slashing. The origin should be the root.
