Escrow issue

The trading network does not have the escrow, the safecoin does not have public ledge. As I know, when transaction of safecoin happens, only A and B two parts know the transaction. So how can guarantee the trade is safe without scamming…
I have confront the scams in btc trading. So personally, really hope safecoin can have a escrow mode for trading. thanks

It will on day 1. Dual signatures can be applied to any trade, so the seller signs then the escrow can complete the transaction or return it.
