Economics of Protocol Design
summary
Claim: using ARC as an offchain channel factory for Lightning compresses funding transactions, saves blockspace, and directly targets Lightning’s main failure mode — infeasible payments — which current measurements put at 97.5% feasibility (roughly 280 payments per second capacity under present assumptions). Multi‑party channels are the only proven fix for systemic infeasibility; ARC’s drawbacks (batched settlement delays, custodial visibility, unilateral‑exit scaling risks) remain, but combined ARC→Lightning topology changes can raise effective throughput by at least an order of magnitude.
