Topic: BlockRace - First bitcoin game that's 100% on the blockchain http://blockrace.co (Read 1814 times)

There is definitely a bot. I checked the site and saw no one had won for 6 hours. I placed a bet and literally 5 seconds later another bet was placed. Indeed the bots are taking a huge risk, but they know that most people are going to make a few bets and then stop to limit losses.

It does indeed look like there might be some kind of bot playing on our site. Notice, however, that even bots do not really have an advantage, and they are actually taking a big risk of not entering a block, and losing their entire deposit.

Additionally, even the bot might *just* miss being the last transaction of a game, so all a bot is really doing, is taking big risks, and we believe that in the long run, it would not be any more, or any less profitable than playing manually.

In any case, we have been offline for a few hours while we made some improvements for everybody, and we're back online now, so we'll be glad to have you all back and playing.

I played a couple of bets and noticed that immediately after i place one 0.01 bet, another one is placed on top of mine, at 5-10 secs. difference.
My guess is you have a 'bot' that places bets immediately after a player bets, to always be the top player and win it all.

I know blocks can't be predicted, but this way you increase your chances exponentially.

I may be wrong, but this is my first impression.
Will play more soon.

Regards.

We had a bit of a technical issue earlier... but everything is back to normal... come join the race to the next block!

is it just me or the site isnt working?

SatoshiDice is not 100% on the blockchain as it uses their own odds generator to determine who wins or loses... see my response #18 above

BlockRace does not rely on anything other than tansactions and blocks on the blockchain. Even if we take the site offline, and come back a week later, we can determine the winners and pay them accordingly. Nothing is needed on our part to make this game work, except pay the winner... which is also on the blockchain.

Yes it was.

No, SatoshiDice is not 100% on the blockchain, as it uses their own odds generator to determine who wins or loses.

https://en.bitcoin.it/wiki/SatoshiDice (Random Number Generation section).

Our game relies simply on the last transaction to enter the next block to determine the winner. No external information other than what's on the blockchain is needed to play the game, and at any moment, one can visit https://blockchain.info/address/1RaceBKYh5saS5D54vbNzPrLjWENviBMR to see the past winners, past prizes, current players, current game state, etc. 100% on the blockchain. That's what this game is

Was SatoshiDice not 100% blockchain based?

Ok thanks.

That's just how bitcoin works. Sometimes it's because the transaction didn't include enough fees and the miner didn't pick it up. It could be because the transaction didn't propogate enough to reach the miner. It could be that it uses an unconfirmed input etc. That's why we add a generous 0.0005 BTC fee when we pay the winning transaction, to get the miners to pick up our transaction, plus the previous transaction, in case it didn't include enough fees.

Why are some transactions not confirmed on the first attempt when block is solved?

Or more chances of losing more

Basically a lottery, and the more you send the more chance you have :O

Sorry about that... wanted to get attention to our cool new concept... and in fact, I did play and win 0.04BTC, and in fact, I did not think of this myself (my partners did)... but the point is - nor I (even with my control of the site), nor anyone else, can really cheat here... I would be taking the same risk as anyone else if I send in money, and I have the same chances as everyone else to win.

That's how elegant the idea is. Even I can play and I wouldn't have an advantage over the others.

Anyway, we're working on more functionality all the time. The clock that Joohansson mentioned is apparently a bug, but you can be sure that the actual time the system uses is taken directly from the blockchain.info API. The time displayed in your browser is client side, and is to give the user indication of the length of the block. All transactions are validated, and the winner is determined by the server.

Obviously, all this is on the blockchain, so it's all there for everyone to double-check. We have no intention of cheating, nor the possibility (as funds are released at the end of every round). We're smart enough to realize that if this turns out to be popular, the best bet for us is to keep it honest.

So thanks for playing, come back again... you'll see more cool stuff then.

I check it out and join to play

I just had to try this, and won =) I can confirm I sent 0.01 and received 0.02. The pot was 0.06 but two unconfirmed transactions. Site seems legit. But the time counter was strange when I played, it showed the time for the second last block at blockchain.info but now it seems correct. I can't figure out what was happening there but probably a bug.

Epic Fail.

Awesome!
