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.
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.

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.

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://bitcointalksearch.org/topic/the-rafflebit-winners-circle-because-youre-awesome-30515 that show proof from random members of the community endorsing the honesty of the platform.

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.

I'm not sure I get what your hashing thing does. It appears you are picking a certain ticket such as the 5th ticket to win but hashing it? Then, when the 5th ticket wins you are releasing what the original text says?

We have updated the pot size to help finish off the beta process. The pot sizes were to small creating rounds that were to fast and not well balanced.

New pot size varies from 1-5 btc.

Have fun playing.

Alright, folks! Got a few things added to the http://www.RaffleBit.com system. We now have proof-of-honesty, where each raffle's winners are picked before the raffle starts and hashed, then released. When the jackpot is paid, the original string is released and the honesty of the match can be verified.

Also added a pot-splitting feature. Now, 1st place wins 60%, 2nd wins 25%, 3rd wins 15%. Everybody wins Smiley


So far, we've had quite a few BTC run through the system, and it seems to be functioning well. Many bugs have been squashed, and much progress has been made. Thanks for your help and patience, and we hope you continue having fun playing RaffleBit!

It's worth mentioning that the first few beta rounds went off with a hitch or two, but some crucial bugs in the code got worked out. So far, the system's working pretty well. I've got a few revisions in mind, but I'll be toiling away to improve the app and we should be out of beta, and in to full 5-25BTC rounds, pretty soon!

Well, you could just look at random.org's data yourself?
Everyone will get a different number.

Yeah, I've looked into it and there's no way of doing lookups on random.org generation history. I'll continue to work on scalable solutions that don't involve using a semi-random block method, or a lotto-number-matching system. As it is, the random.org works great and it'd be nice to see some activity Smiley

You could just dump out the hash of a PRNG seed then after each round give them the actual seed.

see void srand($seed)

Excellent approach, I'll look into something along those lines.

As I've designed it, the raffle is not able to be subverted in any way, and the games move so quickly that a scam-style RaffleBit would be nixed by the BTC community very quickly. Rounds are designed to sell out over the course of a few hours. If 2k people a day were paying attention, the system would get a bad reputation really quickly, and stop being used!
 Grin
You can subvert it. I bet you could take thousands and thousands of dollars worth of BTC before anyone would suspect something was up with your picking method. The more popular it is, the easier it is to continue taking money without anyone suspecting anything. Everyone is anonymous. It's to be expected that the winners are unknown.
