Ark: your gateway to Lightning
summary
Bark is a live ARC implementation that uses VTXO trees and a funding+exit chain to preserve unilateral custody while enabling pooled onchain efficiency; rounds currently run 1 hour by default. Design shifts from a CLARK-style protocol to HARK with cosigners remove strict simultaneity so mobile wallets can delegate signing to many ephemeral cosigners. Rounds sweep expired trees onchain, delegated co-signing is one-out-of-n for availability, and ARC can act as a channel factory to cut onboarding fees and enable cheap monthly splices.
