Analyzing XC mixer transaction by spamming.



Dev refused bounty.

http://cryptexplorer.com/address/XVrqrpe2ZDmykAnjcAHN6McbuDEjBZSvRZ


There is the wallet that received a mix transaction...




lets start with this wallet that received a payment from the mixer
and we can walk through it backwards


I'll make it easy

this is the received mix transaction


http://cryptexplorer.com/tx/9bc580ea9b7ec69d53dbc28e9cc42f1ea810925137d6cc8c1011e904f7c18bac#o0




and you have address XZvkTGD9hMiRuMByqCkHgRTNAu5J5fWnJV - which made the payment




Okay so we know 2 things, XZvkTGD9hMiRuMByqCkHgRTNAu5J5fWnJV  SENT a payment to XVrqrpe2ZDmykAnjcAHN6McbuDEjBZSvRZ


now - can that be tied back to the original transaction?Huh










Hmm. I don't see any link back to the original transaction




maybe this will help


original transaction --->>>> which was sent TO this address "XYyMMG1VQHyRhAQWGdRQ9AEfdwSuG7w18G"


http://cryptexplorer.com/address/XYyMMG1VQHyRhAQWGdRQ9AEfdwSuG7w18G


so now I've revealed the transaction ^^^^^ with this data you should be able to find the original senders wallet ^^^^^^ then take that original senders wallet and search XVrqrpe2ZDmykAnjcAHN6McbuDEjBZSvRZ for the link





what is his point? the mixer address [output] used for this transaction is visible? well of course it yes, we aren't using quantum physics to send the coins, the issue is the mixers input address and original senders output address


since we provided the "last leg"of the TX, he can only back trace to the mixer itself, so far he has NOT Proven anything else



So when you send from original address A to the receiving address D , it goes to the mixer B, the mixer makes a new address C to send the amount to the receiver D? And Chaeplin doesn't get only A?

And chaeplin is adding that the mixer only uses one address for you, so once you know A, you can trace it. Which is what I said before. You have to assume A is known.


that is not how the mixer work's


The highlevel summary is this

The mixer tells the client to send coins to wallet b, however wallet C is used to send coins to the final user, there is NO link from wallet B to wallet C unless somebody manually moves the coins from C to B




seeing how the inputs at http://cryptexplorer.com/address/XYyMMG1VQHyRhAQWGdRQ9AEfdwSuG7w18G are unspent, you can't - it is impossible


ah, somebody is spamming that address w/ transactions 0.003 and 0.03


It's me, sorry.

Now you get my point.

XYyMMG1VQHyRhAQWGdRQ9AEfdwSuG7w18G is a NEW address aka wallet b.

this is the received mix transaction

Simple python scripts analyze the transaction.
Dev wants hard link.

Now where is link between
XZvkTGD9hMiRuMByqCkHgRTNAu5J5fWnJV and XYyMMG1VQHyRhAQWGdRQ9AEfdwSuG7w18G


Easy part.

Mapping.

If there is many transactions, We don't need this.
Block explorer will show the link.

x11coind sendmany 123 '{"XYyMMG1VQHyRhAQWGdRQ9AEfdwSuG7w18G": 0.003, "XZvkTGD9hMiRuMByqCkHgRTNAu5J5fWnJV":0.003}’

!

Watch out.

When coins is spent, hard link will appear.
