# Messages
|
|
|
|
In this section we describe the processing of the crisis messages and the
|
|
corresponding updates to the state.
|
|
|
|
## MsgVerifyInvariant
|
|
|
|
Blockchain invariants can be checked using the `MsgVerifyInvariant` message.

|
This message is expected to fail if:
|
|
|
|
- the sender does not have enough coins for the constant fee
|
|
- the invariant route is not registered
|
|
|
|
This message checks the invariant provided, and if the invariant is broken it
|
|
panics, halting the blockchain. If the invariant is broken, the constant fee is
|
|
never deducted as the transaction is never committed to a block (equivalent to
|
|
being refunded). However, if the invariant is not broken, the constant fee will
|
|
not be refunded.
