What I really appreciate about Rene’s work is that it pushes Lightning Network discussion into a more rigorous mathematical space. Too often, conversations get trapped in either anecdotal experience or surface-level technical chatter without probing the structural limitations in detail. By framing payments as shifts in wealth distribution across a constrained topology, Rene is essentially giving us a mental model for why certain payments fail before they even have a chance to propagate. That is a more fundamental insight than simply observing failed transactions in the wild.
The point about multi-party channels is particularly important. If you care about Lightning reliability you cannot just tune fees or routing algorithms in isolation. You have to reconsider the architecture itself. Multi-party channels are not just a scaling trick; they alter the feasible state space of the network and that directly changes the economic behavior of participants.
That said, the critique about endogeneity of topology is spot on. In the real world channels do not exist in a vacuum. Operators will strategically open and close them in response to routing opportunities and this dynamic element needs to be incorporated into modeling if the ultimate goal is predicting reliability. In economics we often deal with systems where network formation is itself part of the equilibrium and Lightning is no different. If Rene’s framework could be expanded to include adaptive topology, it would bridge the gap between theoretical feasibility and the evolving reality of Lightning.
