BitLotto - best odds + best payouts + cheat-proof

When a round starts, the 3 winners of that round are chosen. The source of the winning ticket numbers is random.org, which uses ambient atmospheric signals to generate random numbers. The winning tickets are converted to a tiger192,4 hash, and the winning ticket string for the last round released after it ends. This enables you, the user, to verify that we, the operators, aren't monkeying around!
Can you give an example from a previous round showing all the steps so I can see how it's done? I'm still not certain what the hash accomplishes or how exactly you are picking the winning ticket.

Alright, I guess I'll connect the dots for you. Although, I have to say, the site's pretty clear as far as what the hash does, and the previous round is there for you already, but whatever.

Random.org selects some numbers, encapsulates them in a string, and hashes it.
Winning numbers for next round(tiger192,4): cdec4577078b5e6f93780776bba72e9c1b4d48fc840633bc

That's the hash for next round. Write this down if you have doubts about rafflebit's sincerity.

That's the winning numbers from last round, encapsulated in a string, and released since the last round's winners already got paid out.

Hash: e436a8dd1f85cf8805c1d10ff6eca74b6a0b5a9487a10e4b

This is the hash of the above string from last round. If you had written the hash down somewhere, you could compare these two things to your record to verify that the numbers are genuine. We even link you to http://www.whatsmyip.org/hash_generator/ on the FAQ to endorse honesty-verification. And things like http://blockexplorer.com/address/1HeySQD9yMJLWcs7SEGCZrbtLh2Bf1dhJZ that prove payouts. And https://bitcointalk.org/index.php?topic=30515 that show proof from random members of the community endorsing the honesty of the platform.

Thank you. Perhaps I'm slow? Wink I was just curious if your method prevented you from knowing the winner or being able to manipulate it.

Does random.org hide what the string actually is until certain date or do you know the string for who wins the whole time?
Are the numbers used for the order based off of blockexplorer for when they paid? Would 0 be the first ticket and 5 the 6th ticket?

No problem, I'm sure the truth-verification system is confusing for most first-timers. The string/winning numbers are hidden from me and set at the start of the round, so there's no way to manipulate the system. I can change the source code to display the winners if I need to, but the display in my terminal is minimized anyway since there's so much output data, so all of the number-display functionality that was present in dev has been stripped out. I have no competitive edge, even if I was ethically unopposed to participating in RaffleBit(service op shouldn't stand to gain beyond what's disclosed to customers).

In programming terms, yeah...0 is the first ticket, and 5 the 6th. The numbers of the tickets are based on the order in which they appeared in the blockchain, but not based on blockexplorer.



This is what I'm talking about, as far as verbose output, and the priority for space over seeing winning numbers. It also demo's what my actual interaction with the backend of RaffleBit looks like.
