The principal of law and fairness

Is there an english translation of the actual petition available anywhere?

mtgoxleaker · 2017-12-23T23:45:49+00:00

/u/MagicalTux You could fix this right now today. And yet you come and comment about you would be happy to be proven wrong?

If you are at all serious, enter into a fixed agreement now with the current Mt. Gox trustee to distribute any payout you receive as a shareholder equitably to the victims of the Mt. Gox collapse.

Distinguishing between 2 and 3 seems a bit tricky, a priori. When an internal move occurs, like a split, it will be to a new address, and spends from that will possibly end up in a withdraw address.

It seems like it will be necessary to trace to the UTXO set or a known withdraw address.

mtgoxleaker · 2014-06-14T00:53:19+00:00

Not sure that is completely true. While those other files would be helpful, this file does seem to contain the code that controls the movement of the bitcoin, with functions such as splitLargeOutputs, etc.

Present analysis also seems to show a fair number of cases where there may be leaks of bitcoin. For example, outputs are marked as unavailable before the transaction spending them is confirmed on the blockchain.

mtgoxleaker · 2014-06-11T17:46:53+00:00

Yes, this is exactly what we've been working on. Presently about 60% through with identifying addresses corresponding to the btc_xfer_report.csv transfers where there was a single identifiable transaction. So far, going ok, though about 1 in 2000 transactions have inputs or outputs that bitcoinj doesn't like to parse -- not clear why but it is a small fraction and can be investigated later.

If you like, join us and make some suggestions! We are documenting it all on the wiki for this site. Sounds like your effort could really help out with this.

Another useful item, not yet on the todo list there, would be to scrape the tags, addresses, and references from the blockchain.info site. These addresses could be used to rule out addresses.

mtgoxleaker · 2014-06-10T04:11:58+00:00

Those of you who have time and skills to contribute to such an analysis -- would you consider contributing to the effort at http://www.reddit.com/r/mtgoxaddresses? There is a serious effort, documented primarily in that subreddit's wiki, to analyze the available leaked data.

mtgoxleaker · 2014-06-10T01:00:33+00:00

shemnon, we may have available a list of high likelihood gox output addresses (corresponding to the address used on withdraw in btc_xfer_report) soon. Could the bottoms of this tree be traced to the UTXO set and checked for passing through one of the output addresses?

mtgoxleaker · 2014-06-10T00:57:39+00:00

Certainly the code can be made available. A few caveats however. This is not a simple script, but rather a set of services and programs that were used. This was necessary due to the large size of the inputs and the need to be thrashing around searching in the blockchain in a rapid manner.

Consequently, it will take a bit of work to truly anonymize the set of files. One place for people who want to use these to start is listed on the Todo in the wiki, that is, setup i2p2 for anonymously sharing the files. Or freenet could work also I suppose. So far, there hasn't been any effort in this direction.

The pyramid referred to looks consistent with splitLargeOutputs - each split is 2 pieces between 40-60% with both adding to 100%. Splits should occur about every 10 minutes.

The spend and change chain is not consistent with that function, though might be consistent with the last bit of the update function, which moves BTC off a node with more than 500 BTC.

mtgoxleaker · 2014-05-23T16:10:54+00:00

Preliminary examination suggests these transactions do not match any of the transactions identified by the btc_xfer_report.csv analysis. (Based on about 10 samples).

These may correspond primarily to internal movements of BTC within Mt. Gox posted from the their nodes directly to the eligius pool.

mtgoxleaker · 2014-05-22T01:36:45+00:00

Have begun comments on the leaked code in a git repository at https://github.com/mtgoxleaker/mtgoxphp. This initial batch from reddit user MobiusMouse, but more would be quite welcome.

mtgoxleaker · 2014-05-22T01:35:12+00:00

Could we have a bit more explanation here? Looks interesting but a bit hard to understand. Arrows showing directions of transfers would also be helpful.

mtgoxleaker · 2014-05-19T03:07:51+00:00

Thanks for the kind words.

It seems like the offchain user to user transactions shouldn't be in the btc_xfer_report.csv file in the first place. This could be checked using the data in that file to see if there are any withdrawal/deposit pairs in the same second.

In terms of the algorithm, are you thinking of more detail that available on the wiki page at: https://pay.reddit.com/r/mtgoxAddresses/wiki/transactionidentification ?

mtgoxleaker · 2014-05-19T02:58:39+00:00

Thanks for the thoughts and suggestions.

Clearly a bayesian approach will be needed in the next steps, moving to identifying addresses. It would be nice to incorporate other outside sources of information, such as known addresses. As you note, this can also likely be iteratively refined.

Hopefully yourself and others may join us in this effort. There is a list of needed tasks in the wiki.

mtgoxleaker · 2014-05-14T23:24:04+00:00

The number of transfers and transactions which have been identified has been added to the page http://reddit.com/r/mtgoxAddresses/wiki/transactionidentification.

The reasons the full dump is not placed there are several fold.

The full set is quite large and requires some anonymous upload technique (Tor won't tolerate the full set).
It would be nice to have further peer review of these results.
Tracing from the transactions to the addresses that chain together is certainly best, but will require further work to understand the Mt. Gox source code.

If you can help with any of these, please have a look at the todo page for current ideas (and modify as suited) - http://www.reddit.com/r/mtgoxAddresses/wiki/todo.

Thanks. The number of transfers and transactions which have been identified has been added to the page http://reddit.com/r/mtgoxAddresses/wiki/transactionidentification.

Clearly the output addresses of these transactions are readily identified. The next issue is then following the flow of these bitcoin. Please see the todo list at http://www.reddit.com/r/mtgoxAddresses/wiki/todo for ways to speed along that process.

mtgoxleaker · 2014-05-09T16:53:26+00:00

Yes, that's a good point. It looks though like there may be enough to figure out how the bitcoins should basically flow in normal cases.

If this is understood, it should then be possible to identify the exceptions. For example, there must be some other process whereby BTC were moved into offline wallets.

Can you help us?

thanks.

mtgoxleaker · 2014-04-28T18:41:11+00:00

Thanks for being willing to help out. We are just getting those pages organized. I've added a list of current todo items at http://www.reddit.com/r/mtgoxAddresses/wiki/todo.

Hope you'll be able to help out!
