Re:
So the way I was thinking of composing them doesn’t quite work, but the construction in State Channels and Plasma Cash should be enough. It achieves the assignability and atomicity criterion with the same collateralization requirements, as well as all 4 extensions.
You’re going to have to use hashlocks if you want to cover microtransactions or smaller transactions - I think ecrecover costs ~$10 to use on the main chain right now?
Sure, you could say that the cost could be greatly diminished on plasma, but i would prefer we stick to a standard across all chains
