Nov 2019 - May 2020
We introduce a health measure for the lightning network that is created from the overall health of single par- ticipants. The health of a node is defined of how even the funds of the node are distributed over its channels. We provide a re-balancing algorithm together with a communications protocol that allows a subset of nodes to improve their health.
