NHZ is a coin that some people have been working with that show up on the mumble hangouts. This is either implemented or what they are working to implement.
Is it anything but an escrow system ? So anyone can have a futures contract if they put up escrow and the source of the escrow decision can be trusted to make the correct decision.
I didn't read the article, just your quotes. Meh unless there is more to it.
Lol - Do they mention how they put USD in a wallet by any chance ?
Actually this would likely be some future addition to a BTSX now that I think about it..
2nd edit - No probably not. We have bitUSD + price feeds so it would never need to be a multisig account. I mean unless a consensus network controls the third account, then it is centralized. TBH I don't even really know what "smart contracts" are so maybe I should shut-up.
