Are you sure that the accounted has posted atleast once in every 2week period?

The account for sale has posted quite frequently, except between November 2014 and January 2015.

so how much activity it can possibly get just by posting? i might bid to this if this can reach Sr Member just by posting or nearly Sr

I'm not sure but in my case I have a 2013 account and the activity increases a lot. From that, I guess that the activity increase by 1 per day of existence.
Your activity = your posts except if your posts > total days since registering. Then if your posts > activity, activity = days since registering. (being updated every 14 days)

If the account is more than one year old, you should easily get at least around 350 activity. Senior member kicks in at 240 so you'll have it for sure with that account.

Could someone confirm ?

Bonjour, et merci d'avoir cliqué sur le thread français consacré au FAILcoin !

Je m'occuperai de répondre à vos questions et d'annoncer les informations relatives aux évolutions du FAIL.
Également, je pourrais faire remonter vos différentes remarques à l'équipe et faire le lien avec vous.

Ce projet est fun. Nous faisons les choses à notre rythme. Le plus important, à mon humble avis, est d'avoir une équipe constituée de personnes dignes de confiance.
A force de pousser dans une direction commune, nous finirons par arriver là où nous voulons aller. Smiley

Feel Bad?  did he feel bad for all the players that lost there money to not truly fair game?  "What goes around comes around"

This is not the topic of that thread. There are already countless accusation against Stunna for that reason.
I think their algorithm is fair. I don't recall that Stunna forced any player to deposit BTC on PD. However having someone to take advantage of a design flaw is always unpleasant...
3806  Economy / Gambling / Re: Provable fairness good practices on: April 15, 2015, 03:35:30 PM
@boopy265420: thanks Smiley

@elm: Not yet. Stunna promised to write a blog post about it but didn't yet, you can keep a lookout at http://blog.primedice.com/ Personally I am definitely looking forward for the details about it as a hobby security researcher, although I definitely feel bad for Stunna (and rest of PD team) for the loss.

@NLNico
thanks for explanation. do you have any explanation in mind? I was sure that PD's provably fair option is 100% secure.
is there a 100% secure provably option for the player and op?

I might be totally wrong, but from what I understand, the player secret was generated based on time.

That cheating player could have created 2 accounts at the same moment, and used one with small bets to see what was scheduled for this player secret.
When he found the right player secret he just went high stakes with it. Since he knew the outcome of the bets, he could roll max bet every time and be guaranteed to win.

It reminds me of the almanac in Back to the future.
I feel bad for Stunna tho.

To get back to the topic, I am more intrigued by provable fairness but using the different bitcoin block hashes to make the calculations.

What do you think of doing this ? => sha256("block_hash"+"server_secret") with server_secret being changed and revealed every 24hr to allow verification of previous bets ?
As long as the server_secret doesn't leak, no miner can calculate the outcome of a bet before broadcasting some block.

Also, does someone remember BitMillions ? (http://bitcoincasinopro.com/wp-content/uploads/2013/10/bit-millions-main-page.jpg)
I'm curious about what happened to them. I'm not sure their provable fairness algorithm used some kind of server secret so it could be exploited easily.

Hi everyone, Dan Palmer from igot here. Any issues, please feel free to email me at dan[at]igot.com.

You should try to send an email to the address above. Maybe this representative will be able to help you further (or will help you faster) than the support team.

Until now , I still have not yet got a respond from "yogg" as he said.
So that's the second reason I have not used that account to do anything.
You must ask yogg to give signed message. You may get into trouble sooner or later without it.

I kept BTCBLOGGER's funds until he provided a signed message stating he asked me to sell his account.

I got it, then I released the funds. Now I just sent to OP that signed message from BTCBLOGGER and another signed message from me, stating I sold such account to OP on behalf of BTCBLOGGER.

I really don't get it.
Admin is talking about BTC50 .. BTC100 wagered.. within one week  Huh

If the site is really able to gather so much interest from players, why hold BTC0.68 and create such a drama ?
The profits should be way higher than BTC0.68 if the site gets 100BTC wagered.

You said "marketing". But here, you're clearly destroying your hard work by showing you don't want to process a withdrawal.

If you made a mistake with some promotion and made it possible to gain advantage on the website to some cheaters, then you either have to prove they cheated, or just stick to your word.
You had a player who deposited. And now you're holding his coins. Imagine how everyone feels about depositing on your site.
If you can hold someone withdrawal like this, why not hold everyone's coins ?

Still, it's you, admin, who made that promotional offer. You're the only one to blame there.
3810  Economy / Gambling / Re: girlbtc.com || new site || jackpot 0.01btc everyround || simple||transparent on: April 15, 2015, 07:22:02 AM
Admin claims there are cheaters. How would they cheat ?
There are people claiming their funds, withdrawals are not processed.

From what I saw it first took some time to process withdrawals if Google 2FA wasn't enabled..
I wonder if it's not some lunatic way to delay the withdrawals.

I'm not sure what's happening and I don't want to go through all the pages.
Please, can someone recap what's going on there ?
3811  Economy / Gambling / Re: girlbtc.com || new site || jackpot 0.01btc everyround || simple||transparent on: April 15, 2015, 06:39:19 AM
This admin is crazy. this is his way of promoting his site? Shameful!!

Bad advertising is still advertising, they say...

Good luck to everyone who has some coins in there.

Hello.

I was wondering about the different ways we can implement provable fairness to different games.
This is truly a great concept, but we have to make sure it can't be exploited by some smart player.

What would be the best way to do so ?

I mean, most of the dice sites use a combination of :
- Some <player secret> variable.
- a hidden and later revealed <server secret> variable. This variable should be changed regularly.
- Maybe a nonce like "Bet ID".

This solution seems pretty safe since no once can predict the result of some bet. The server secret in use is theoretically unknown from players so no one can calculate a bet outcome before it takes place.

What about blocks hashes ?

I remember http://www.bitmillions.com .. It was a lottery game. There was a draw every time there was a new block.
In this case, the block hash only was used to calculate and pick up the winning numbers.
Now, this site is down for about a year, I'm not sure why and when it went down.

I liked that website. It went down without notice and I never saw any more news about it.
What could possibly have happened ?

As far as I understand the provable fairness concept, they could have been exploited :
Some miner calculates a block but doesn't broadcast it right away. He first plays on bitmillions.com with the winning numbers (since he knows the block hash because he found one).
Then, when his participation is confirmed, he broadcasts the block and boom he gets the 1st prize.

The jackpots were progressive, and the top prize was about 1,400 BTC before it went down.

Maybe this is what happened ? I mean, if a game outcome is based only on the block hash, any miner can do the calculations to determine the outcome and bet accordingly.
Would that be doable ? Is it what happened ?

If yes, what would be the best way to prevent this ? Could we simply add some secret <server hash> that changes every 24h and use it with the block hash in the calculations ?
What would be the best way to implement provable fairness in a game based on the block hashes ?

I really understand how difficult it is to come up with a provably fair algorithm that won't be exploited.

Thanks for your answers. Smiley

What you got available to loan bro

Hello.

Nothing yet.
I loaned 0.1 BTC to BitBerau. He should have repaid now. He sent me a message a few days ago, but is not responding to my new messages.
If the loan is not repaid before the 16th April, I will sell the collateral.

If this was true, and if the guy could come up with the original silkroad, he should have the funds or skills or team to build the site he's talking about, and not begging for 5 BTC...
