The Lightning Network (LN) is a second layer solution built on top of Bitcoin, aimed to solve Bitcoin's long transaction waiting times and high transaction fees. Empirical and theoretical studies show that the LN is tending towards the hub and spoke network topology. In this topology most of the nodes, the spokes, open a single channel to one of the few well-connected nodes, the hubs. This topology is known to be prone to failures, attacks, and privacy issues. In this work we introduce the Maypoles protocol in which most nodes open two channels instead of one. We show that this protocol benefits the network significantly by enhancing its stability, privacy, and resilience to attacks. We also examine the economic incentives of nodes to take part in Maypoles.
