I hope you don't mind, but I build my transaction manually, turns out it began with a 7! I must be lucky today.

if txhash[0] == "7":
print "collision found"
print txhash

break

What is this sorcery? Are you hacking?

EDIT: Anyways: my 3rd and last transaction has the two confirmations.

The chain must hate you. Maybe more miner fee's will get you lucky.

I'm almost sure he has scammed. And, like that person just shown, you can keep building rawtransactions, then signing them when you get a 7.

Painted the OP red.

I'm dabbling in Bitcointalk again - I won't be making trades with people. If I try to trade with you, ask for a signature from my address 171717... which I have had control of since about 2015. If I can't provide it, I might have been hacked.

Seems a bit early don't you think? He's done successfull deals selling ASICminer coupons, doubt he'd scam like this. Calm it with the negative reputation.

As you wish, but I'm pretty sure he'll get some red as a form of TWC further down the line.

Also, he went offline barely 1 minute before this:

Pretty sure he saw your bets...

And finally, when taking into account that he needs to pay 5x on what you both gave him, the total amount scammed comes to just below 0.7 BTC.

*Thank you, and good night.*

ogrgat, the first warning is that the topic is self moderated.

The second is that you don't know that people can submit selective transactions, I can keep generate transactions until I get one with the proper begging and only then broadcast it.

I don't know if you're being sarcastic, but I will assume you really don't know how the bitcoin transactions work:

Have you ever tried to sign the same message using the same address twice (Original Bitcoin Client format)? You will see that the signature won't be the same. And this is exactly what happens with a transaction. Every time you sign the same transaction, you will get a different txid.

Looks like the OP doesn't know about it either (or he's pretending that he doesn't know about it).

not a custom txid like "aaaaaaa...a" but you can keep signing a created raw transaction until you find a txid that fit your needs. That's why satoshi dice use secret server seeds.

https://en.bitcoin.it/wiki/Raw_Transactions

Not custom txids, but custom transactions, basically everytime you run signrawtransaction, a random number is used in the ecdsa signature generation, this is the signature is the first few bytes in the sigScript.

Run signrawtransaction enough times and you'll end up with a signed hex transaction which will equate to a txid which begins with a 7.

Example how it works.

Step 1 .... I send some Btc amount lets say .. 0.1 Btc to the exact wallet

You see, even his example amount was 0.1 BTC, HIGHER THAN ANY BET YOU BOTH MADE, and there was no mention of a maximum bet amount.

Now, it is a scam, because he's getting out of paying you the owed excess. Whether he overlooked raw transactions or not, he still owes you because of what he stated in the OP. Time for some red, and it's justified now.
