Payment channels, in traditional sense, are fully collateralized credit. I suggested to leave collateralization ratio up to users themselves. Some could have 100% collateral, some 0%, some 50% etc.
Rejection reason: unclear, doesn't fit the narrative.
Payment channels are not at all credit. Credit means you're relying on someone to pay you back, and have a risk that they won't pay you back. Credit relies on trust. Payment channels do not rely on trust. You can always retrieve your money even if your channel partner doesn't want to give it back.
