[Development]SatoshiRat - a bitcoin game

This might be a stupid question, but why are the Server seed generation delayed? See this ---> http://prntscr.com/lbchsl  <Should this not be displayed immediately to show that the seed is not rigged?>

I use Freebitco.in Multiplayer Server seed as an example, because that is given as a verification, the moment after you placed a bet, so there are zero delays to provide the Server seed.

The same server seed is used for 10 games.

It is generated before the first game starts, and a hash of it is presented to the players.
When the server seed is revealed you can check the hash to be sure it is the same server seed.

This way you know it wasn't changed for the last 10 games.

After 10 games are played the server seed is revealed and you have all the data to use the formula and compute the rolls to be sure all rolls were correct.

Additionally the formula uses the timestamps of the blocks each transactions were included (first confirmation).
This timestamps are impossible to predict in advance.

If you have more questions please let me know.
thx

I think need redesign provably fair algorithm because need publish seed before game.
Or make easy it, not all player understand how it works..

ServerSeed must be published after the game not before as it is used in the rng functions. Before the game you get the sha1 of the ServerSeed. After the game you just check the sha and it should be the same and you know this way the server seed was not altered and is the same and was generated before the games. (You can see the hash of the current server seed on "Fair" page but i also added it to the game lists to be more clear)

Also take into consideration multiple games can start at the same start as it happened in the past. That is why the same server seed is used for 10 games, cause otherwise the second game that starts the same time as game 1 can have it's seed manipulated cause server seed, the game, and revealing of the server seed happens at the same time. Players have no way of knowing it was generated before the game.

Also if you look closely at the formula, as a second precautionary measure, even the first rat's roll uses data from the last rat that enters the game(timestamp of all rats first confirmation.) This way even if someone knows the server seed(sys admin, db admin , hacking) in advance, he still can't predict a thing, cause he needs to predict the timestamp of the the last rat, which is impossible.

Agree, I don't mean clear seed, need hash of server seed before game.
How can possible use timestamp for provably fair game?

Well any random, unpredictable, verifiable, public variable is good for any algorithm.
In this particular case it defends against malicious admin knowing the server seed. Please read https://www.satoshirat.com/index.php?page=fair for how the algorithm and timestamp of first confirmation is used.

In this game you don't play against the house, you play against other players, so it is a bit more tricky to ensure fairness for all participants against each other than playing against the house.

I agree on the thing you have said shows on bolded one but most people nowadays will really prefer showing of not only on last 10 games but it would be much better if it shows on every game.Confidence will always matter on players side.

can you check the following? after 7 confirmations still no entry at your page
transaction id

I think with the bitcoin price been so high than other crypto currencies its not something to play around with it is rare it is scarce why in the world you are required create a game out of it. with bitcoin been such an important store of value lately. No one will ever dare to play with their btc such an game.

[nutildah]

Its been 5 years since anyone posted in this thread, yet the game is still going 

https://www.satoshirat.com/

Are bets still being paid out?? Each bet costs 0.01 BTC minimum so I don't think I'll be partaking 

But it was just interesting to see the website is still up and the rats are still running.

Oh, it looks like the last race was in Nov 2018:

Oh well, kudos to the creator for continuing to pay for hosting and server fees all these years, its like a blast from the past.
