I believe the block size limit issue is getting critical. You guys should check out Reggie Middleton's Veritaseum. Quoting:
thank god he renamed from "ultracoin".
Pretty bold claims from Middleton, but I have tried it and it works, at least in a beta phase, not vapor phase or proof of concept phase, but beta phase. You can trade all tickers that Cypherdoc mentions on here.
I still don't understand how the tickers are fed into veritaseum to settle the bets. Can you explain that?
