I am the owner of anno1777 labs, the company behind great games like anno1777 or goldentowns (anno1777 was sold this year). Goldentowns is quite popular here.
The game's currency is GoldenTowns Coin (GTC). There are 100.000 GTC in circulation, 100% backed by gold.
What you see is a small wallet to allow players to spend the coins outside the game. It was nice addition to GoldenTowns, but its a simple centralized, client-server application written in flash. It took around 2 weeks to write it. It's nice, has some app written around it but it's nothing compared to MaskNetwork.
We took the interface, rewrite everything in java, worked for 12 months in a row and you are going to see the results in August.
We have 5 years of writing extremely complex real money social games.
No, those who wrote MaskNetwork are not newbies programmers...
