You should add a thing to sha256 a text field.  I liked having the list of emails be hashes.
Done. Works for emails, I'm not doing any input validation, so you can probably confuse it by pasting a bunch of junk into the input field.
Don't forget to lower case the input for those who don't realise that upper/lower case is not relevant in email addresses Smiley

I didn't like that, it becomes easier for a raffle operator to disguise his own fake entries (instead of showing forum user names, etc., which allows us to intuit that every ticket purchase in the list is legitimate).

Not sure that clear text email entries help that much. One can easily create a series of different email addresses that really have the same owner.

The only issue is the "remainder" greater than the max multiple.

10 hex digits = 16^10 = 1099511627776

1099511627776 / 40270 = 27303492.12  (that last 0.12 is unfair)

So max valid random number is 40270 * 27303492 = 1099511622840

Matt a "fix" is simple and fair.

If the value of last 10 digits of the block hash is > 1099511622840 then it is a "no-go" and you use the next block.

Don't worry the odds of that happening are very small.  Only 1099511622841 to 1099511627776 are "bad".  4936 unfair numbers out of 1099511627776 or 0.0000004%

I have updated my raffle ticket picker here: http://we.lovebitco.in/raffle.html. It will now alert you if the hash is greater than the last modulo interval with a full number of tickets (however you would describe that). Just so everyone knows they have an absolutely equal chance of winning.

Feel free to pore over the javascript source and try to break it or find any type of unfair calculation. As an example, in this raffle (with tickets 0-40269), the highest hash without error is FFFFFFECB7, which gives #40269 as winner; FFFFFFECB8 or higher gives an error.

Large hashes near the maximum are also only a problem if 0x10000000000h is not evenly divisible by the number of tickets. For example, with 65536 tickets (0x010000h), a hash of FFFFFFFFFF is still valid.

BTW, even with a raffle happening every block, this would likely never happen in your lifetime...

I'm going to hang myself if c267a549d21a37b371b8d4fa5b944d55bd5624dfcc735f4045031fd53a640bff didn't win

Congrats, man!

Did your piss stain just get bigger?

I would wager on it being BitScalper. He doesn't like it when I provide proof of him being a sociopath.
