On this episode of “The Van Wirdum Sjorsnado,” hosts Aaron van Wirdum and Sjors Provoost are joined by Lightning developer Joost Jager to debate the whole lot about Lightning Community routing.
What Is Lightning Community Routing?
The Lightning Community — Bitcoin’s Layer 2 protocol for quick and low-cost funds — consists of a community of funds channels. Every fee channel exists between two Lightning customers. Even when two customers don’t have a fee channel between themselves straight, they’ll pay one another although one or a number of different Lightning customers, who in that case forwards the fee from the payer to the payee.
The problem is {that a} fee path throughout the community should be discovered, which permits the funds to maneuver from the payer to the payee, and ideally could be the most cost effective, quickest and most dependable fee path obtainable.
Jager explains how Lightning nodes at the moment assemble a map of the Lightning Community, and what details about the entire (publicly seen) fee channels is included in that map. Subsequent, he outlines on what foundation Lightning nodes calculate one of the best path over the community to achieve the payee, and the way the efficiency of this route elements into future path discovering calculations.
Lastly, van Wirdum, Provoost and Jager focus on some (potential) optimizations to learn Lightning Community routing, equivalent to rebalancing schemes and Trampoline Funds.
