Exactly, as a holder of StableCoins myself I've been waiting on it's mixing service to come about with great hopes for it. Sadly it seems that the developer announced it and hasn't done much since. The beta signups were a good step in the right direction but I haven't heard anything since then.

I'm not sure what's taking them so long, the way I implemented it in FedoraCoin is almost exactly the same way they planned it for StableCoin, but we managed to get a actual proof of concept running in less than 6 hours, with a working usable beta running in less than half a day. Compare this to StableCoins 6+ months of waiting and you'll see why I'm surprised it's taking them so long.

I actually hope that StableCoin manages to bring it out soon because I'm interested in how they plan on implementing it, the way that artos originally described seemed good on paper but when it came down to developing it I realized it'd require everybody to be running the latest version, which would be a miracle in the world of cryptocoins (There's still people running FedoraCoin 0.43, which is 2 versions older than the current version!)

I wish the best to all StableCoin holders. Maybe now that there's a competitor with an actual working mixing service this will help to bring StableCoins service up and running soon.
