FYI: Recovered most of my unfinalized orders from Hansa. This includes both 2 of 2 and 2 of 3 tx's. Orders that were placed during the few days that the multi-sig transactions had been altered to send output to police controlled wallet of course were gone. It must be said that if anyone had verified their multi-sig tx's via coinbin would have seen that the tx's had been altered, the blockchain doesn't lie.
Any market not implementing this system is pretty much planning to take your coins, or they are too dumb to be running a market.
tldr: multi-sig with timelock totally works, vendors should verify each tx before shipping orders. the end.
Any current market that provides timelock transactions?
