Outstanding. Looking forward to having a play with this.
Could be used to buy/sell crypto currencies by storing the address and private key and releasing them to a buyer? Or do I misunderstand?
I think so, yes. There is a danger that the seller would spend the coins at the same time as he sells them. But I think I read on the other thread that somebody is working for atomic cross-chain transactions, which would solve this issue, but I don't know a lot about that.
Good to see this discussion continued here, hard to follow in the massive Nxt thread. I still like the idea of magnet links listed in the client, click and the marketplace GUI is loaded into the client. There was a BTT member (Fry) that was interested in developing. Would love to get more brainstorming here, this could be a great thing to have.
I'm creating a command-line version as a proof of concept. I'll probably offer a bounty for a GUI version.
