Trampoline Routing Mobile / light Lightning clients can't sync the full 50,000-channel graph efficiently. Trampoline lets them target trampoline-capable nodes, which then do their own pathfinding to the destination. Why Pathfinding cost: - Full sync: 50-100 MB graph + 30 minutes initial sync. - Memory: 50-100 MB resident. - Update bandwidth: continuous gossip rate. For battery-constrained mobile, trampoline shifts this to a server. Mechanism Sender constructs a 2-layer onion: - Outer onion : routes to trampoline node, payload is opaque. - Inner onion (encrypted) : contains target destination…
