ODD - EVEN win 198% | Provably | House edge 1%

[crazybtrade]

No, what I said is correct.

1. There is no way to verify at which specific point you get the trade data. Just a few milliseconds later, would result into a completly different result. I gave a pretty easy-to-understand example of this. Look at the link you gave me:

{"date":"1481768751","price":5435.7,"amount":76,"tid":"107799733"},{"date":"1481768751","price":5435.7,"amount":14,"tid":"107799734"},{"date":"1481768751","price":5435.7,"amount":4,"tid":"107799735"},{"date":"1481768751","price":5435.7,"amount":2,"tid":"107799736"},{"date":"1481768751","price":5435.7,"amount":2,"tid":"107799737"},{"date":"1481768751","price":5435.7,"amount":71,"tid":"107799738"},{"date":"1481768751","price":5435.7,"amount":333,"tid":"107799739"},{"date":"1481768751","price":5435.7,"amount":508,"tid":"107799740"},{"date":"1481768751","price":5435.7,"amount":43,"tid":"107799741"},{"date":"1481768751","price":5435.7,"amount":36,"tid":"107799742"},{"date":"1481768751","price":5435.7,"amount":8,"tid":"107799743"},{"date":"1481768751","price":5435.7,"amount":1,"tid":"107799744"},

12 trades in 1 second, all timestamp 1481768751. All of those traders affect the volume (and sometimes the price.) You can pick the volume you like and there is no way for the player to verify it. Therefor it is not provably fair.

2. There is no fixed timestamps on transactions. Each node can see a transactions at a different timestamp, because it takes time for the transactions to be relayed through the bitcoin network.

We get volume from https://data.btcchina.com/data/ticker?market=btccny

example:
{"ticker":{"high":"5460.00","low":"5376.71","buy":"5446.03","sell":"5446.21","last":"5446.03","vol":"1099575.40990000","date":1481785161,"vwap":"5431.94","prev_close":"5442.93","open":"5443.2"}}

by timestamp one volume.

If our game can say not provably, that btcc.com is not provably too.
but i trust btcc.com.

Trust != proof.

Besides that, I am not even questioning the data from BTCC. I don't think your wager volume is enough for BTCC to be malicious.



I am saying that we have no way to verify at which point YOU get the data from BTCC. It is very easy to say that the transaction was 1-2 seconds earlier or later at your bitcoin node. This would result into completely different results and there would be no way for the player to verify the bet result. You could make the player lose every bet and there would be no way for the player to verify and prove if he was cheated or not.



Your site is not provably fair. You should either fix the provably fair method or stop promoting your site as a provably fair site.

This is not scam, we get real data form btcc only.
We fixed it in result table.

Please try our game and check result..

Thanks!

I am not saying you are a scam. I am also not saying that you are cheating. I could believe that you are honest. But provably fair is not about believing or trusting.

Provably fair is a way for the players to verify and prove if they have been cheated or not. On your site, they cannot verify and prove this, because using "timestamp" is unreliable as shown in my previous posts. Therefor the player just has to trust you to be fair.

That is "trust us, we are fair" and not "provably (=you can prove we are) fair".

[crazybtrade]

We get real data from https://data.btcchina.com/data/ticker?market=btccny

example:
{"ticker":{"high":"5460.00","low":"5376.71","buy":"5446.03","sell":"5446.21","last":"5446.03","vol":"1099575.40990000","date":1481785161,"vwap":"5431.94","prev_close":"5442.93","open":"5443.2"}}

by timestamp one volume and one price.

if wanna check your bet player can contact with support btcc.com and request the volume and price by needed timestamp.

for easy we can remove Volume from hash and still price only. ok?

[NLNico]

You cannot use timestamps if you want to be provably fair. There is no fixed timestamp at bitcoin transactions. There can be a 0 - 10 second delay EASILY between when a bitcoin node gets the transaction. You could maliciously change the timestamp to 1,2,3,4.. seconds later to make the player lose. There is no way for the player to verify if you did this. Therefor it's impossible to generate a provably fair outcome with this.



I replied to your PM already too:

I never really looked into secondstrade. It is possible that some of their games are not provably fair too.



LuckyBit uses a correct way to calculate provably fair bet results for on-chain games. They just use a hash of:

<tx_id>:<vout_id>:<secret_key>

vout_id is the output index, in case of multiple bets in 1 transaction. Secret key is a daily secret, all hashes of future secrets are published already. Then after midnight they release the secret so people can verify the hash and also the bet outcomes. More details on LuckyBit.

This could work for your ODD / EVEN game as well.



Of course there wouldn't be any relation with the bitcoin price anymore though.

I agree with NLNico.

Indeed there are trades even in between a second. He already showed it. How do we know the system chose the correct one by the time we placed our bets? Because indeed there is a time stamp but it only shows it by the second and not milliseconds. Therefore, if there are 10 transactions in one second, how do we know that the system did not pick a number that is favorable to the site?

exchange use standard Unix timestamp kind of 1481677011.

the exchande not use milliseconds!
step is one seconds.

You can try our game.
please make min 0.0005 bet.. and check it

I am confused why you guys want it to be provably fair since it uses the data from the open market which is VERY EASILY verifiable to be provably fair. Just take a bet, and see if the price matches or is close to the market rate for BTC/CNY and you have your evidence.

It is literally impossible to verify. Did you read my posts or not really?


Even in your post it's not provably fair: "if the price matches or is close to the market rate".. even 1 CNY cent difference would make a completely different result. This "game" is not predicting a price, it's just using the price in the hash generation.

thanks for giving insight NLNico. provably fair is important because this determines the winner and if in the case the owner can manipulate the transaction by just a millisecond this is a failure. im not saying the site owner is doing this but we can say 1 out of 10 is the site owner. you can see the effect.

im not accusing anybody, peace.

I agree with adaseb.
very easy to check bet.
I tried this game and won, got all winnings.


I know that some dice sites use fake provably seed..

also NLNico message about luckybit

why do you think luckybit use [secret_key] ? for provably fair system no need [secret_key]... if it is blockchain based game.

[chixka000]

You guys has your own opinion and those needs to be respected. The thing here is that have you tried the game before saying so?

Anyways i have here my current bet result

I bet .0013 and choose the odd result and won .0024

[NLNico]

Why would I try it? The game is not provably fair. That is a fact.

He might run a fair game.. sure. But that is "hopefully trustable fair", not "provably fair".

Thanks for the nice bonus. However is it possible to add more pairs like BTC/USD, or ETH/BTC or ETH/USD. Or even Forex pairs like Gold, Oil, Eurusd, GBPusb. We are bitcoin gamblers need a reliable Binary website because many of the current ones are reliable with payout problems or admin issues.
