+* Finding new peers
+* Uploading blocks
+* Downloading blocks
+* Daemon maintnence/housekeeping
+
+## Files
+
+* \_\_init\_\_.py: Contains the main communicator code. Inits and launches the communicator and sets up the timers
+* peeraction.py: contains a function to send commands to remote peers
+* bootstrappers.py: adds peers from the bootstrap list to the communicator to try to connect to them
+* onlinepers: management of the online peer pool for the communicator
