A (mostly) visual collection of the Lightning Network

Disclaimer

Network views tend to be the view of the network from a single node, or small selection of nodes. They are not complete views of the network. This is impossible to achieve. Even if many node views were combined, it would still be incomplete.

These network views, or network maps, have been termed 'visualisers' by the LN community.

Screenshots may reflect older visual styles, and are dated accordingly.
