 <p>Say you have 5 channels. Yo uwant to be pretty clear that they are actually yours. So you can build network graphs. If you just have a bunch of edges, you can't sort of link them all together into a vertex, it doesn't help. But if you say this edge and this edge are all connected, even if I'm not using the same public key for these 2-of-2 multisig, I must have had a key in common to generate all of these.</p>
