Re: Ask HN: Where are the 750k Bitcoins lost by Mt. Gox?

In November of 2011 Mt. Gox demonstrated control of 500k BTC. I followed the 500,000 BTC for a bit beginning at https://blockchain.info/tx/b269bf1b82dae8a61f7f91dbf7a9d807e... . The coins move around and small amounts are sent away, but the majority ends up back in Mt. Gox's main (hot) wallet. This repeats a few times until the majority is paid back to the main Mt.Gox address. Here is the transaction where it starts…

I wonder, can this trace be automated?

Some info here: http://www.reddit.com/r/Bitcoin/comments/1z37zw/mt_gox_has_a... "MtGox still has at least 200k BTC" Here are the possibilities, as far as I can tell: 1) That information is inaccurate. 2) MtGox lost their private keys. 3) The private keys were kept in a bank vault, which was seized by a foreign entity like the US government at some earlier time. 4) MtGox stole the coins. The management of MtGox knows…

5) they were stolen

that is #2

Why doesn't Mt. Gox just publish the ID of the wallet(s) from which they were stolen? 1. They weren't stolen - lost in cold storage harddisk failure for example 2. Revealing it would show something extremely embarrassing - they only used a single wallet? 3. They still have them - yay? 4. They were stolen by Mt. Gox - gulp

MtGox may just have larger problems right now and can't get around to the actuarial work involved.

Though I agree a cold storage failure is still a good possibility, given the poor communication.

With the possibility of getting down voted into oblivion. The BTC lost/stolen are all available within blockchain/public ledger. Depending on who stole them, it would probably be distributed within multiple very smaller transaction. It my be traceable, but likely unrecoverable, because this is a feature of Bitcoin. In other words authorities and forensic enthusiasts can find the BTC but they are most likely lost at t…

I wouldn't be that pessismistic. If people manage to identify people behind the blockchains, I strongly suppose that law enforcements, depending on countries where the theift physically is, can force the thieft to give it back without any modifications to existing laws. I think we can catch him when he is going to want to laundry his bitcoins.

The community really needs to choose one of two messages:

a) Bitcoin is pseudonymous enough that you can safely buy drugs with it

b) Large thefts of bitcoin can be traced; it's not pseudonymous enough for massive frauds

Which is the same as 2) and 3).

Can anybody follow one of these "branches" until the very last known transaction on the blockchain? Would that clear anything up?

Yeah, people have been trying all kinds of analysis on these addresses on r/bitcoin this week- So far the jury is out as to whether meaningful info can be gathered in this way.

It must be. Has anyone built a transaction tracer? Perhaps a visualizer using d3?

"Coming together" is a bit difficult to determine -- how do you identify a large group of recipient addresses as a single entity? How do you differentiate between a group of addresses belonging to a single owner, and a group of addresses belonging to multiple owners?

We can construct a graph tree all destinations beginning from that one address, but what good would that be? Where do you make inferences to determine the identity of the recipients? How do you group them together?

At some point your trail becomes so long and so disparate that any effort to continue following that trail would be a pointless endeavor.

Sure the technology is there to follow the trail indefinitely, and (where available) you can easily check all recipient addresses from this "poisoned" tree against regular fiat exchange logs, but within the BTC ecosystem? It's an interesting intellectual challenge, but not useful.
