I have been visiting Berlin to attend the second lightninghackday and want to give a brief wrap up about the event. This article will basically cover two topics. 1st as promised within my bar camp session on “Building an automated topology for autopilot features of the lightning network nodes” I will give an extensive protocol / summary of the session itself. 2nd I will talk about an already well known technique called splicing which I realized during the event might be one of the more important yet unimplemented features of lightning nodes.
