Bitcoin Forum

In view of the thefts occurred in gox (if true), poloniex, flexcoin and since bitcoins are traceable. Wouldn't it be good to create a list to trace the movements of stolen coins for, at least, they can not be sold in major exchanges?

No.  This has been discussed to death, but in short fungibility is good, whitelists and blacklists are not for a variety of reasons, including, who decides what coins go not the list? Who enforces it? Etc

Indeed.... that is what will make more h@x0r5 want to attack... :)
But what can we do. Sit and watch :) (+10 popcorn)

+1

no but if u do find them u can sit at ur PC and make a bitcointalk.org saying


AH MA GAWD STOLEN BITCOINS JUST GOT SENT INTO BITSTAMP!!!!!!


then we all go OMG HAXOR CASHING OUT


then someone goes IS IT MARK CASHING OUT OMG

then starbucks see a 2 percent rise in sales

then we go to sleep.

Yes. and everything going back to normal :)
after we wake up.

Certainly no and there is no benefit and point in tracing those transactions back and i think i have read about this on tis forum somewhere before as well !!!

If you mix the coins you will not be able to track it anyway.

Besides, who decides what to blacklist?

Its completely trackable is most cases and should be.  Exchanges should be involved in investigations, tracing addresses and fiat exit points.   this is unquestionable.  If they don't , bitcoin will be stuck.   If the community can show some policing at least in major thefts, it would be a huge boon for the success of bitcoin.  The exchanges should openly participate in theft forensics.  You cna track forward in the chain from thefts and backwards from exchanges where the biggest fiat transactions should be traced backwards and see if the trails connect for suspect accounts/addresses.   

Bitcoins cannot be stolen.
Private key can obtained from someone's machine but nobody can claim sole ownership of a private key.

Get tracking coins out of your head. It will never happen.

It's guaranteed to happen in cases like this.

Its not as easy as it sounds, people use tumblrs to distract those searching for thefts.

You track the coin and then what? You can't prove anything...

Once they exchange for fiat, you have whatever country they are in investigate them for taxes and sources of income.  If they can't prove where the cash to get the bitcoin came from, confiscate the cash.  Rinse and repeat.

It would be better to have the industry standard that all exchanges' wallets are being made public (tagged in blockchain).

When your stolen coins appear on an exchange's tagged address, you would simply notify this exchange that the coins that were stolen from you have just arrived in their wallet. The exchange knows who funded the wallet with your stolen bitcoins and can give the name of the thief to the police for further investogation.

marking coin looks infeasible but we can try to trace these guys.

Look at my post in the meta forum, it seems someone has found the guy who stole flexcoin according to the taint analysis he sent me. I posted it.

I'm a huge fan of this.

I believe it is still traceable although it is a much more sophisticated process.
