Topic: SatoshiCircle.com Official Launch (Read 5308 times)
I guess the game has changed a bit since we made the last video review here: https://www.youtube.com/watch?v=gw93GXVbqYY ??
could u pls give me a contact email adress?
Very nice website will deposit some coins to test it out 
The site stopped this morning. I have some btc deposited but i can't withdraw it as server is off. Is my money lost?
I'd say you should probably write it off, I hope it wasn't a lot. OP hasn't been online since August 2014 and their Twitter account is inactive since around the same time. I highly doubt they will reach out to members who've still got funds there. But you never know.
Thank you, the site started working but some bad things started to happen. I wrote about it here: https://bitcointalksearch.org/topic/satoshicirclecom-official-thread-731924
I won some BTC yesterday and i can't withdraw it. When i press "ok" nothing changes. And even after that i can't spin the wheel anymore. If i try to play using another account everything works fine.
i have created a new Satoshi account, won more that 1 BTC, but after i try to withdraw it my NEW account stopped, wheel is not spinning and withdrawal can not be processed. Satoshi seems to be scam. I will keep you informed but be careful.

Hello all, maybe you can help me. I just made a deposit, and I did it twice. Unfortunately, it is showing up. Has anyone had that problem? I kept refreshing the page as suggested, but it is still not showing up. I am open for any suggestions.
I have the same problem right now. What happened to you later?

I really liked this site! Just cashed out 0.3 BTC from my 0.01 BTC deposit
that's a lot man, congrats! how did you get that much, care to share your experience here ?
Yea, adrenaline were pumping man..
Don't know really, incredible lucky and bet with a wager big enough so you could lose some spins in a row. Also take some huge risks sometimes
That's what I did.

Satoshi Circle game is NOT provably fair.
They use the following model:
1. The outcome of the game is fully determined by initial data in a way, known to the player.
2. Part of the initial data is provided by the player ("Client Seed").
3. For every possible variant of server's data, there exists a variant of player's data that makes player win.
4. The server proves that it didn't change its data after the player revealed his part of the initial data.
5. After the game, the player can compute the outcome himself and verify that it matches the actual outcome of the game.
I will show that the outcome is determined in an unknown way, which invalidates the provision (1).
Here is an excerpt from the algorithm published by Satoshi Circle:
This is the implementation of rand in PHP 5.5.0 (ext/standard/rand.c):
So, we have many possible PRNGs, and in fact, many different algorithms for computing the outcome.
How it theoretically can be used by Satoshi Circle to cheat. Suppose, a player makes one large bet, and it is his first bet. After the player discloses his "client seed", the server tries several PRNGs and uses one that gives the worst outcome for the player. Then Satoshi Circle claims that it is "the" PRNG they use.
Also, even if PRNG algorithm was known to the player, it is still difficult to verify the outcome.
1. When I try to select the hash of the server data to copy-paste it, the "client seed" entry form pops up and the text that I try to select goes to background.
2. The scheme used to compute the outcome is excessively complex. There exists a scheme that would provide at least the same level of security for the Satoshi Circle and the player, do better randomization of the outcome, and is easy to compute by an average player.
3. To verify the outcome using the current scheme, the player needs exactly the same PRNG. It may be a considerable hassle to get one for some OSes.
That all discourages players from verifying the fairness themselves. Most will hope that someone else will find it out if Satoshi Circle is cheating.

Here is an excerpt from the algorithm published by Satoshi Circle:
Code:
function seedShuffle( $items, $seed ) {
if (is_numeric($seed)) {
$seedval = $seed;
} else {
$seedval = crc32($seed);
}
srand($seedval);
for ($i = count($items) - 1; $i > 0; $i--) {
$j = @rand(0, $i);
$tmp = $items[$i];
$items[$i] = $items[$j];
$items[$j] = $tmp;
}
return $items;
}
This function is central in determining the outcome. It uses PHP functions rand and srand. The underlying PRNG algorithm has roughly as much influence on the outcome as the initial data.if (is_numeric($seed)) {
$seedval = $seed;
} else {
$seedval = crc32($seed);
}
srand($seedval);
for ($i = count($items) - 1; $i > 0; $i--) {
$j = @rand(0, $i);
$tmp = $items[$i];
$items[$i] = $items[$j];
$items[$j] = $tmp;
}
return $items;
}
This is the implementation of rand in PHP 5.5.0 (ext/standard/rand.c):
Code:
PHP_FUNCTION(rand)
{
long min;
long max;
long number;
int argc = ZEND_NUM_ARGS();
if (argc != 0 && zend_parse_parameters(argc TSRMLS_CC, "ll", &min, &max) == FAILURE)
return;
number = php_rand(TSRMLS_C);
if (argc == 2) {
RAND_RANGE(number, min, max, PHP_RAND_MAX);
}
RETURN_LONG(number);
}
{
long min;
long max;
long number;
int argc = ZEND_NUM_ARGS();
if (argc != 0 && zend_parse_parameters(argc TSRMLS_CC, "ll", &min, &max) == FAILURE)
return;
number = php_rand(TSRMLS_C);
if (argc == 2) {
RAND_RANGE(number, min, max, PHP_RAND_MAX);
}
RETURN_LONG(number);
}
Code:
PHPAPI long php_rand(TSRMLS_D)
{
long ret;
if (!BG(rand_is_seeded)) {
php_srand(GENERATE_SEED() TSRMLS_CC);
}
#ifdef ZTS
ret = php_rand_r(&BG(rand_seed));
#else
# if defined(HAVE_RANDOM)
ret = random();
# elif defined(HAVE_LRAND48)
ret = lrand48();
# else
ret = rand();
# endif
#endif
return ret;
}
As you can see, it uses one of 4 possible PRNG functions. Which one is actually used, depends on the PHP build. One of the back-end functions, rand (as defined by C standard), has implementation-dependent algorithm.{
long ret;
if (!BG(rand_is_seeded)) {
php_srand(GENERATE_SEED() TSRMLS_CC);
}
#ifdef ZTS
ret = php_rand_r(&BG(rand_seed));
#else
# if defined(HAVE_RANDOM)
ret = random();
# elif defined(HAVE_LRAND48)
ret = lrand48();
# else
ret = rand();
# endif
#endif
return ret;
}

Server not found. Hopefully not when someone deposited 50 btc or something and the site owner ran.

Guaranteed not to spam the blockchain. Only deposits and withdrawals go through the chain.
We'd love feedback and recommendations on improving play for a new game we just launched tonight. We'd also appreciate tips on the best place to market the game. Here's the live radio spot we did tonight on Free Talk Live, a nationally syndicated radio show on 100 stations in the U.S....they love talking Bitcoin.

How do I know you're not scamming me?
Any Bitcoin gambling that's not independently verifiable is broken. This is exactly the opposite of what this nitwit says:
Does satoshicircle bloat the block chain in the same way satoshidice does? If not I would use that in your marketing. Are the transactions off-chain until you withdraw?
Unless you're "spamming the blockchain" it's not gambling, it's a scam.

Glad to have some more visually-appealing games out there, thanks for this one.
Thanks! Over 15000 spins in just over a day!
