I am trying to recover an old CoPay multi-signature wallet and want to find the keys that were on a device as a co-signer. I still have the physical iPhone, which has been upgraded and restored several times, as well as many backups of the iPhone. So far as I can tell, these keys were not stored in the backup, but perhaps I am mistaken.

If the keys are not stored on the backup, where were they kept on the device?

I am trying to understand better what happened technically with the Bitcoin Cash SV (BCH-SV) split.

What is puzzling me is that I recently created a Bitcoin Cash (BCH) wallet with an old private key which had bitcoin at the time of the BCH split in 2017. It showed the balance of BCH, which I then sent to another bitcoin cash address in a different wallet (wallet #2).

Now when I try and load that old key into a BCH-SV wallet, it shows the movement of the BCH and says that there is no BCH-SV balance available.

When I import from wallet #2 into a new BCH-SV wallet, is says that I can split the BCH-SV off.

I am not understanding what is happening here in terms of the blockchains. Why would a transfer of the BCH at a date after the BCH-SV split in 2018 result in BCH-SV being available? Are they somehow marking transactions on the BCH blockchain as either BCH alone or BCH and BCH-SV being moved?

UPDATE -- please see my last post in this thread. This was caused by some confusion on my part about keys.

When creating a multi signature 2 of 3 wallet using a combination of xprv and xpub keys, it appears that the addresses created by Electrum (v 3.2.3) depend on the particular combination of keys used. For example, say there are 3 keys, A, B, and C.

Wallet 1: One creates a view only 2 of 3 multisig wallet using the 3 xpub keys, xpub A, xpub B, xpub C.

Wallet 2: create a new wallet using 2 of the 3 private keys. If one uses xprv A, xprv B and xpub C, the same addresses are produced as Wallet 1.

Wallet 3: create a new wallet using a different set of 2 of the 3 private keys, say xpub A, xprv B, and xprv C. This wallet now has a different set of addresses.

This does not seem correct. Any ideas on the problem or what algorithm Electrum is using?

Do people have a suggestion for a reasonable amount of RAM and storage to run the Lightning Bitcoin linux full node wallet? I'm trying to setup a new machine to do so. Thanks.

What are people's opinions about the best companies/exchanges for a US resident to use to sell larger numbers of bitcoin?

Does anyone have any knowledge about who was running Vircurex? I had some coins deposited with them from way back and only recently went back to review the history of their apparent scams.

It seems they are not answering any queries at this point.

While they have not formally announced it, BTC-e recently stated to me that they are no longer dealing with US banks or customers.

This would explain the lower price of BTC on that exchange as USD would be relatively more scarce there.

News on the BTC-e site now that there is a 2 week delay in USD wire transfers due to banking problems.

Anyone have further information or insight on this?

Does anyone have a link for the list that was circulating of Mt. Gox employees and their contact information?

Specifically, I would like to know a current address for service on the following individuals as well as the names of the attorneys representing them:

Mark Karpeles
Gonzague Gay-Bouchery
Jeb McCaleb
Marion (a woman who worked on the support desk and claimed to be from management).

thanks,
Peter

Given the lack of information coming out of the trustee for Mt. Gox in Japan, I'm beginning to think another class-action lawsuit in the U.S. may be the best way to go. The settlement with Sunlot is a pile of nonsense in my opinion -- how can one reasonably agree to a settlement before one even knows what was going on at Mt. Gox?

My understanding is that the class in Greene vs. Mt. Gox was never certified, so that it should be possible to start another class action, does that seem correct?

I am also searching for the Motion for Preliminary Injunction of April 8, 2014. According to exhibit 2 of the preliminary settlement, this 34 page document sets forth the results of the Plaintiffs discovery efforts. It seems like this could be an interesting read. Any pointers?

Hi All,

Having read through most of the posts in this forum concerning keywords like those in the title, I thought I would start a new thread for those block erupter cubes which are really unreachable on the LAN port.

That is, I have a cube hooked to a LAN with a computer on the 192.168.1.0 subnet. I have factory reset the cube multiple times. The cube powers up and has a link light on the LAN interface, but is not reachable at its nominal address http://192.168.1.254:8000. Furthermore, it doesn't respond to a ping or to a broadcast ping.

What is the best procedure for trying to get one of these to work under these circumstances? Is there a known method of using the USB port to interrogate this or reset the firmware? Any documentation on the USB port?

thanks,

Given the possible recent leak of the Mt. Gox source code and database, what would the core developers and mining community think of locking the apparent large wallet balances belonging to Mt. Gox, Mark Karpeles, and Jeb McCaleb by changing the protocol for now?

The idea would not be to accept any transactions spending these bitcoin until the Mt. Gox bankruptcy case is sorted out. A committee, possibly appointed by the Bitcoin Foundation, could verify proper ownership before the coins are cleared for spending and a change back is made.

This would be a bit different than the idea of taking the coins permanently, or permanently invalidating them. The intention here would be to simply assist the legal process.

I know this is not something which can be done for every theft, etc., but we are talking about 6% of all bitcoin mined to date, which are presently tangled up in a real legal mess.

I suppose a general principle to govern this could be that when an entity controlling greater than some number of fraction of bitcoin is subject to legal action, such as a bankruptcy, charges of fraud, lawsuits, etc., that coins may be locked pending the outcome of litigation.

As I've noted previously, we are now putting together a group working with a law firm in Japan to represent the interest of Mt. Gox creditors during the civil rehabilitation procedure (similar to Chapter 11 bankruptcy in the USA).

Some significant issues we hope to address are the potential criminal negligence involved, protecting remaining assets, and a fair and appropriate treatment for bitcoin assets.

We are looking for additional creditors to join us in legal actions. If you are a Mt. Gox creditor with more than 40 BTC or $20,000 (or equivalent Euros) on deposit with Mt. Gox and would like to join us, please pm me including your email address and name. I will then add you to our email list for updates regarding our actions and thoughts on proceeding.

I was just thinking more about potential solutions to the Mt. Gox situation. Firstly, this is assuming a disaster has occurred and that Mt. Gox has lost control of its cold storage and that noone else has the private keys (thus, they aren't stolen). This is also assuming that the full records of Mt. Gox transactions can be obtained (possibly by subpoena in bankruptcy proceedings).

Under these circumstances, if a majority of miners agreed, would it be possible to hard-fork the bitcoin protocol to just nullify their transactions using their cold storage after a certain date and implement appropriate transactions using a wallet under supervised control to obtain an equitable settlement for all parties?

It seems unlikely this disaster has occurred, but I guess we shouldn't underestimate the level of incompetence in handling there at Mt. Gox.

Does anyone know which Japanese law firm has been representing Mt. Gox?

Another possible explanation of the recent Mt. Gox problems occurs:

Could it be that they were just served today with papers regarding a lawsuit with an injunction, or an involuntary bankruptcy. This combined with a perhaps petulant reaction by Mark Karpeles?

Many commentators here have complained for a long time about the continued trading for a long time in the presence slowed or absent withdrawals.

An injunction or involuntary bankruptcy proceedings might well require immediate suspension of trading. Additionally, there may have been part of an order demanding the removal of the misleading (at best) statements on the front page.

And if you were going to skip town, why call attention to it by suspending the website?

While the multi-party lawsuit is an interesting civil case against Mt. Gox, it may be that a better approach for locking down records and increasing pressure on Mt. Gox to fix the withdrawal problem would be reporting them to the criminal justice system, with complaints of fraud.

It appears that both the Antimonopoly Act and the Unfair Competition Prevention Act in Japan may cover making deceptive promises and statements.

The other advantage of a criminal complaint is that it would hold the CEO responsible, versus the corporation itself.

Is there anyone in Japan who could contact the appropriate authorities?

Looks like CampBX may be down for some maintenance. There was a page saying they would be back in 15 mins, now offline.

There is an ongoing attack on wallet.dat files which were created by the old Apple BitPak client program.

The developer stated that the wallet.dat file was backed up in encrypted form on DropBox. This client program was removed from the Apple Store in mid-2012, but people may still have backups on their Dropbox account.

It turns out these wallet.dat files were not encrypted, and consequently there is an ongoing attack right now which is hacking into people's DropBox accounts, where passwords may have been obtained due to re-use, stealing the wallet.dat file, and then stealing the bitcoin.

The wallet.dat file backup for this old client is unencrypted and can simply be downloaded from DropBox, then dropped in as the wallet for Bitcoin-QT and the coins removed.

Whoever it is has been removing the bitcoin to address 1BjxoP5BDwxPG4myiXhJK8zWownJUbd4K4 and has netted at least 29 BTC so far.

Can anyone help trace who this might be?
