Of course this would require some trust between the parties.
Use Robosats if you do not have that trust. Put the offer on Robosats: I offer 100k CC in exchange for 80k sats. I am coming and take your offer, putting the sats on hold (with a hold invoice in Robosats) until you send me the CC through SN. Once I received the CC I confirm in Robosats and you get the sats automatically. Robosats act as a escrow service.
Trust problem solved already.
We have a market.

Do you trust Darth to play honest?
And when we will have the SN badges implemented we can assign trust badges to others...
