correct, it is kinda like lightning:
  • it is an off chain protocol
  • it allows unlimited off-chain back and forth payments
  • these payments are compatible with and routable through the real lightning network
it is also more scuffed:
  • force closures are less efficient
  • not everything is tested
  • it doesn't have a built in p2p network so it's slower
  • it doesn't use source routing so it's less private
