Hello Kurt ?

  Thanks for your sweet words .

  About your bug , I propose the community of Bitcointalk to be escrow and the judge .

  You explain the bug and the proofs , I give my advice , you can answer , and finally we decide if you qualify or not and the community is witnessing .

  About how much is it valuable i would say that 500 usd is the maximum : a systemic bug .
  An average bug will be rewarded 150 usd .
  

 BTW I don't understand why you signal a bug at the advantage of the client , and in the end of your message you deter people from playing BitRoul threatening them of losses .
  puzzling   Roll Eyes Huh

  

 


BUG IN PROVABLY FAIR FEATURE


The bug: Each time you change your client seed, the unhashed server seed is revealed in the response from your server sent to the browser.

Proof:

I change my clientseed to kurtfoundabug00 in the option provided.
It changes successfully and this response is sent to browser.

As you can see the noramlServerSeed shows the unhashed server seed.

I then take that serverseed and put it together with my client seed and the time I plan to press the spin button and SHA512 hash it.

I then take the hash and convert it to decimal , 2 by 2

I then wait for the time to be 1 second as planned and press the spin button so that the time can be accurate.

Here is the spin Result

More Proof

Look at round 65, I haven't played it yet. The hashed seed is given and my clientseed changed to kurtfoundabug001.

The unhashed serverseed is already in my possession.
