This transaction does not perform any network changes or upgrades and requires manual intervention to restart the network.


A non-freezing operation that initiates network wide preparation in advance of a scheduled freeze upgrade. The update_file and file_hash fields must be provided and valid. The start_time field may be omitted and any value present will be ignored.


Freezes the network at the specified time and performs the previously prepared automatic upgrade across the entire network.
