So, someone finally developed a honest and transparent escrowed ponzi ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) . Good to see such things.

I believe the txid can be changed before broadcasting into the blockchain ![Huh](https://bitcointalk.org/Smileys/default/huh.gif)
Anyone could easily win by simply repeatedly creating raw txids without broadcasting till he gets a txid with a low hex value at the required points.
The system is proven to be fair, to select the random number that determines the order of the payouts, the 13th,14th,15th and 16th character of the deposit TX is used
Example:
TX 0278d4300340724eb37a623089c3398fdaeb34e6a00057f4837c9d3833af5dbf
Would generate this 4 hexadecimal digits 724e So that's 29262 decimal that would be your order number.
Ordered by that method, every user is paid out 135% of your bet until no more funds are available

Suspicious tx in ROund #1 17 1CG1R4BimSyaFUhaEqiANLsuX28UpziYBt 0.09 0.1215 a3f12bb... [007b] 2/1/2015 9:54:03 AM UTC 123 Win d14e39c... The fact that the highest amount was put in by the same user makes it even more suspicious.

Now about the system, It'll be changed to the unix timestamp of the transaction, i.e. for that one https://blockchain.info/rawtx/a3f12bb4f79f007ba4589367aab8e0bcbab90a65faff1d4571de2b5c4dcded8bit would be 1422784443 = 344 I'm almost sure that couldn't be changed, what do you think?

Problem with the system i could keep submitting raw hex transactions and keep going for the tx id that I want, and don't broadcast it if its a txid that makes you win. Maybe hash the tx with a secret key, and you provide the sha256 hash of that secret key to verify that you aren't change it. This would make the random number not predictable if you don't know the secret key, which is released at the end of the day (week in this case)

Doesn't make sense to me Thanks for your reply, You say that the unix time stamp can be changed? The value will be taken from the "received time" by blockchain.info that value can't be changed, can it? Also 00 will win over 01 because the number would be taken from the 3 first digit of the inversed unix time: like 1422265904 = 409. Althought the players could try to get it in the lowest digit it's very easy to fail and get a higher number. Another option is adding the TXID with the hash of the block-height where it was included then hashed again, that way I think there's no way it can be changed, what do you think? Btw, while this get sorted out, the round will be increased by 24 hrs. Btw, we've noticed some other strange transactions.

I think it is okay. ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) Most games like this hash the txid and use it to determine the winner, etc. I personally use blockchain wallet, on which doing so is either not possible or unknown? Just check it with someone else, since personally I am not so much into bitcoin and blockcain tech.

Timestamp cant be changed but you can still resent the tx if the time received is bad. Also anyone can hash block height with the txid and then resent if its bad. Maybe hash the block hash of the next block that it confirms in, I am not sure if you can guess the next block hash but I dont think you can.

Yes! For the first round it was based on some digits of the txid of the deposit (the 1st post has details), but we noticed one player probably tried to alter it to gain advantage, so we're testing and deciding if we go with the unix timestamp of the deposit. i.e. b1efe3ed66420f5c0956dfab0f17baaf08626a763d59501d92f3790c4a1071a9 1423018427 = 724or with the txid + hash of the next block from the block_height that included the transaction, then hashed, then the 13,14,15,16 digit then to decimal, like this: b1efe3ed66420f5c0956dfab0f17baaf08626a763d59501d92f3790c4a1071a9 So: b1efe3ed66420f5c0956dfab0f17baaf08626a763d59501d92f3790c4a1071a9 + 00000000000000000fbceb08d7f309339f2307a5941104dace6da723077f112c (That's the next block hash of the block-height 341854 which included that transaction) Then hashed it's: 4b6ecf89594caff0ef2528e636ee682b774e30ae7a180d534a8e9dc2178081b2 So the digits are: aff0 So the draw number would be: 45040 But, every method can be checked and verified by all users so yes it's provably fair.
