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.
