[docs] """txupdate event reports the confirmation changes of incoming transaction (deposit) or outgoing transaction (broadcasted).
This event is fired for each transaction, when its ``confirmations`` changes. One network transaction may contain several deposit or broadcast transactions and they all trigger the event.
When the incoming transaction is first seen in the network, but it is not yet confirmed, confirmations is 0. Evaluate the risk of `double spending <https://en.bitcoin.it/wiki/Double-spending>`_ for these kind of transactions in your application context.
