I've implemented a BitStream proof of concept by Robin Linus in Cashu for atomic swaps between files and Lightning payments.
Atomicity is achieved via a "Nutbond" Ecash contract which can be challen...
What if the file isn't necessarily what the client was looking for? (i.e. I upload a file called Terminator Movie, but it's actually Star Wars or just the first 30 minutes of the movie or even some kind of malware). Would that punishment just be reputation since the file could still be decrypted properly?
