The object of the game is to determine if an address from transaction C belongs to the same person from transaction A.

OK, let's get started!

Transaction A: Notice it contains 6 sending addresses and two output address.

The first determination you must make is: which output address was the intended recipient?

I don't question the fact that bitcoin users are anonymous.

My question is how will bitcoin survive if the US goes after the exchanges under the guise of AML regulations?

Under the new FinCEN guidance these bitcoin exchanges would have to identify their customers and maintain records of transactions.

Much ado about nothing. Most exchanges, even foreign exchanges, were already following those laws.

So most Bitcoin exchanges have been following all of the regs listed here?

BSA Requirements for MSB's

I find that hard to believe.

I don't know about all of those, but definitely most of them, like ID requirements, KYC crap, etc. MtGox is based in Japan and for a US customer to get an account there, they have to go through many many legal hoops, and it's been that way for a while.


Now, can we proceed with the point of this thread? Or is it going to get hijacked?

So how does that work given the anonymity of Bitcoin? The whole point of a KYC program is to essentially destroy anonymous transactions.

Doesn't my question fit within the topic at hand? The point of your thread was to prove how anonymous Bitcoin is, and how it would be impossible to trace users -- wasn't it?

What is the point of this thread? Is the point that currently bitcoin users can execute transactions that are very difficult to be traced back to them?

If so, who is arguing against that point? No one on this board that I've seen.

It is not hijacking the thread to point out that current virtual currency ID requirements will become irrelevant as new regs are developed on any virtual currency exchange.

The exchanges will be held responsible for being able to identify their customers and if they can't or won't, they will be penalized.

Let's play a game called $100 bill forensics:

Who has used the $100 bill below to buy something?

If you can't identify who has ever used this $100 bill then it proves no anti-money laundering laws can be enforced!

I'll send the link to the FBI for them to get started on.

It only removes anonymity at that point in the system. And like I said, this has pretty much been the case for a while with the major exchanges.

After that, anonymity can be easily regained by performing a few simple transactions within the bitcoin network.

jesus man, does nobody want to play this game?

I asked a simple question (which output address was the intended recipient) and no one will even wager a guess? come on, man.

Completely irrelevant when it comes to enforcing AML regulations. See my $100 bill forensics game above.....

Are we "harassing" you if we think your 'game' is stupid....as well as irrelevant?

Besides, you don't believe in Jesus....

Can you solve differential equations?

Probably not, and neither can I, but there are experts that can. I don't see the point of the question.

It's an exercise to point out some features in the bitcoin system. If you participate, you will learn. But unfortunately, most of you don't actually have an interest in learning how bitcoin works.
