I am trying to gather some data from blockchain for a bunch of addresses for my experiment purposes and I am using Bitcoin armory for the same. I was going through the official website and it says that for doing so I need to read the wallet file, register it with TheBDM, initiate the TheBDM and run armory database with the supernode option. I donot understand what is the "TheBDM" over here, I have looked into armoryengine and there is BDM.py file present. The code that is available online contains whole list of functions applied on TheBDM like TheBDM.setBlocking(True). I am sorry if my question is not clear but I am trying to understand what is this TheBDM. Thanks for your help in advance
