In this post, we summarize our paper on channel balance probing in the Lightning network. It supersedes our earlier work on this topic. A video presentation based on this post (a longer version is also available): First, we briefly introduce the Lightning network (LN) and the channel balance probing attack. Then, we propose an enhanced probing technique that allows an attacker to extract more private information faster. We run simulations based on real-world data and conclude that the propose...
