UdjinM6	a611fc3b1b	Introduce CDSNotificationInterface - validation interface to listen to tip updates and trigger updates in DS, payments and budgets. Should significantly reduce number of references to chainActive.Tip() i.e.we should have less cs_main in dash-darksend thread and potential deadlocks.	2016-03-04 12:10:37 +03:00
