### 6.4 Deactivate
114

-
An on-chain transaction from current controller calling `deactivate(cowHash)` permanently deactivates the did:cow ID.
116
-
117
-
It sets the controller address to `0x0` and the stored wrapped DID to `:`.
115
+
Call `deactivate(initial_controller_address, initial_wrapped_did)` from the current controller to permanently deactivate a did:cow ID. If the cow has not been registered on-chain yet, it will be registered automatically in the same transaction.

119
-
After deactivation, the DID resolves to deactivated status and cannot be reactivated.
117
+
After deactivation, `resolveCow` returns an empty string and the DID cannot be reactivated.

NB: It is permitted to set the controller to `0x0` via `updateController` without deactivating, in which case the DID continues to resolve but can never be updated or deactivated.
