Let's say I wanted to raffle off some steem monsters cards, it would be cool if I could go on your website and put in the raffle details and then your tool could track the entries and pick the winner at the end using your provably fair system.

@yabapmatt, sir what if any bot doesn't vote on my bid . Because 12 hours ago I send 3 steem to @upme and I did not get upvote so far . One more user did not get upvote for 45 steem.
Ah I see that is a cool idea and I will look into it. As for now next week I will be cliff diving in Greece for 2 weeks, so it wont be anytime soon.
As for solving the provably fair aspect. I decided to use the hash of the first Ethereum block found after the deadline. In the new process when a deadline expires, first the public hash from the server seed will be published in a transfer on STEEM. Then when a new Ethereum block gets found this hash will be used instead of the transaction id and also published in a transaction on STEEM.
