It was pretty unstable when I tried it a few months ago.  Kept crashing on me and slowed down my machine even more (Bitcoin-QT already does a number on it).

Will be great when 0.91 comes out with full support for OS X.  I've seen Armory running nicely on Windows so can't wait to have that stability on OS X as well.

Armory Dev Team,

Keep up the good work!

It's interesting to see that this is only active thread I could find in the forum that talked about the price disparity between Gox and BitStamp.

Right now there is a 9% difference in the price at Gox ($107) versus BitStamp ($98).  This has been ongoing for the last few days now, and in past weeks as well.

I'm intrigued; variances like this would never last this long in a mature market.

@rfugger:

If you're worried about the MD5 and therefore the application being tampered with, an SSL tunnel from a hacked server is not going to get you very far.  Use PGP.

Thank you.

Hello Electrum Developers,

First off, thank you very much for an excellent application. I really like it!

I went to download the GPG detachable signature for 1.7.3 on the download page <http://electrum.org/download.html> but the server returns a 404 Not Found error.  Can you please post it so before installing I can verify that the executable was signed by Animazing?  The MD5 hash matches up, but that's really not a good substitute for verifying the signature.

Thanks for your attention to this matter.

I don't see how encrypting a wallet causes new keys to be created. Can you provide a reference to specific examples of this being discussed? I could not surface anything in google on this with the terms you suggested above.


Well, you should backup wallet.dat more frequently if you are using it for a lot of payments and therefore receiving a lot of change, which forces new keys to be generated as you burn through the first 100.

This is not an issue though if you are only using the wallet primarily for cold storage.

That's right. I posted on this here:

Basically just make a copy of the whole Bitcoin data directory and drop it into any computer with the Bitcoin-Qt client installed on it. Make sure the client is not running and replace the existing directory with the copy.
BE CAREFUL NOT TO ERASE ANY WALLET THAT MAY HAVE VALUE!

Of course! Thanks.

Disaster recovery planning.

Does anyone have any idea how to change the default data directory on a Mac? I'm not aware of a "Target" parameter when launching apps in OS X. I've tried googling it but come up with nothing.

OK, understood. But that only helps in meatspace situations. BTC is nice because you can still trade with anyone in the world, including meatspace transactions, provided of course there is internet connectivity.

What are they trading these days with in Cyprus? They still have internet there in spite of their extended "holiday" period.

Worked as expected. I created two wallet.dat files with different public/private keys stored in them and swapped them around at will. Main thing was to shutdown Bitcoin-Qt first, then swap the files, then start it up again.

Some other stuff I tested on two different machines (both OS X running 0.8.0 (haven't upgraded to 0.8.1 yet):

Downloaded entire blockchain on machine A and created a wallet on it too. Installed Bitcoin-Qt on machine B but DID NOT start it up. Instead I first copied the whole data directory (~/Library/Application Support/Bitcoin) from A to B. Then booted it up on B and it synced the last couple of blocks and was up and running nicely without having to sync the whole blockchain from scratch (and the keys from my wallet where there too). So was easy to port everything over to another machine and be up and running quickly.

That was my understanding too. I'm glad to hear that only the wallet.dat file is what acts as the container for the "crown jewels" and that it is as simple as keeping that file well protected. Will test it out to confirm for myself that all works as described in this thread.

Thanks everyone for your questions/input.

How is silver going to be helpful in that scenario? I assume you are talking about a serious currency meltdown such that cross border payments become difficult/impossible.

How do you define a "wide spread disaster"?

It does take some time.

It took me about 20 hours running Bitcoin-Qt 0.8.0 on OS X. My bandwidth usage was pretty moderate though at only a couple hundred Kbps maximum and even then only at times.  Seems this is one of the more moderate cases compared to deepskydiver and others I've heard from who've gone through the process.

Blockchain.info has a good explanation along with instructions about how to generate one securely:

Have fun!
