Hi, I joined the signature campaign, why is not it appearing on the spreadsheet? Will the stakes count for a week from the day I joined or is there a specific check-in day? Is avatar and personal text required? Thanks. Smiley

Hello Karodozo

1. Now you are there in spreadsheet.
2. Stakes counted from the day you've joined.
3. Avatar and personal text give you +0.5 stake per week. They are not required.

Welcome!

Hi,

As a potential investor, I am very concerned by what I have seen looking at your lottery algorithm. There are 2 glaring issues that undermine the legitimacy of your lottery and are astounding given the millions that will soon be raffled on the site.

1) Any customer who has purchased a ticket using number 49 has been cheated. Your algorithm uses modulo 49 which makes it so only numbers 1 through 48 are drawn.
2) Your algorithm discards repeated numbers and moves to the next 4 character section in the hash. This is inherently ok, but there are no safeguards to prevent a bitcoin block hash that generates duplicate powerball numbers exceeding the unique hash length. This may not happen for a long time, if ever, but there are already 18 prefix 0s on the bitcoin block hash, reducing your available seeds for the drawings, and this will only decrease in time. When it does hit, your algo will crash. For a lottery based business understanding the impact of ' small odds', this should go without saying..

https://github.com/TrueFlip/prizecounter/blob/master/algorithm.py

edit: 4 character, not 4 bit
edit2: this also applies to the golden ball with modulo 26

Hello bitboi1

We appreciate your discovery very much!

We will check the algorithm today and give resolution about it in several hours.

If this mistake is exist we will fix it.

Also we will have to make recompense for players with 49 number at their tickets, if this mistake is confirmed.

Looks like you have similar rules for tweets of SONM but this would create a spam like thread and I would suggest to open another thread for bounty and to keep things posted there

Just made new account there but not option to make deposit with other altcoins instead of BTC. Maybe my account have some problems to make deposit using LTC.

It seems I couldn't understand you correctly. You can't buy tickets for alcoins now. Such an opportunity will be available only after the ICO starts. But you will be able to buy tokens for altcoins from June 28.

Best regards,
Trueflip.io


Thanks for this reply I was actually asking how to play lottery with altcoins so that I will wait for June 28 when this will be up for place bets there.

Hi,

As a potential investor, I am very concerned by what I have seen looking at your lottery algorithm. There are 2 glaring issues that undermine the legitimacy of your lottery and are astounding given the millions that will soon be raffled on the site.

1) Any customer who has purchased a ticket using number 49 has been cheated. Your algorithm uses modulo 49 which makes it so only numbers 1 through 48 are drawn.
2) Your algorithm discards repeated numbers and moves to the next 4 character section in the hash. This is inherently ok, but there are no safeguards to prevent a bitcoin block hash that generates duplicate powerball numbers exceeding the unique hash length. This may not happen for a long time, if ever, but there are already 18 prefix 0s on the bitcoin block hash, reducing your available seeds for the drawings, and this will only decrease in time. When it does hit, your algo will crash. For a lottery based business understanding the impact of ' small odds', this should go without saying..

https://github.com/TrueFlip/prizecounter/blob/master/algorithm.py

edit: 4 character, not 4 bit
edit2: this also applies to the golden ball with modulo 26

I am a little bit worried about the big error in algorithm, the equal distribution should be one of the most important elements in a lottery.

Second thing are the names and pictures on your team description site:
https://ico.trueflip.io/newico
Some pictures of the members have different names and are doubled.

Can you comment this please.

I hope you get a good bounty. That was a monumental error you discovered.

I think there is a market for a blockchain lottery not sure this is the team for it but I will read more.

I am a little bit worried about the big error in algorithm, the equal distribution should be one of the most important elements in a lottery.

Second thing are the names and pictures on your team description site:
https://ico.trueflip.io/newico
Some pictures of the members have different names and are doubled.

Can you comment this please.

Hello Frank37

Thank you for your concern about it.
It is great luck that bitboi1 discovered bug like this!

This page https://ico.trueflip.io/newico was from test period of developing site. That period delelopers didn't have the pictures from all the team and marked with doubles places for them.

Thank you for find it, now it is blocked.

Best regards,
Trueflip.io
