Thanks for sharing this

Creating a Bitcoin client that fully implements the network protocol is extremely difficult. Bitcoin-Qt is the only known safe implementation of a full node. Some other projects attempt to compete, but it is not recommended to use such software for anything serious. (Lightweight clients like Electrum and MultiBit are OK.)

A big fan of VM's myself, how about getting a VM (Used to use VMWare, but VirtualBox fan these days) of your favourite distro up and running, install all of the necessary software, take a "snapshot" of it (shut down is safer, but you can "snapshot" a running VM).  Do your wallet transactions inside the VM after booting it up, transfer the file to cd/usb stick/whatever..., shut down the VM reverting to snapshot.  Then you won't be needing to install the software every time, but you still get the benefit of having a system which doesn't actually contain your wallet.  If you are extremely paranoid, download the software installs separately and install them in the VM while not connected to the web.

I'm not sure what the VM gains you.

Like the live cd, your "wallet" is NOT on the disk (in this case image).  Any traces of it are disposed of when reverting to a snapshot.  Unlike the live cd, you only have to install the bitcoin software once.  If you really know your stuff, install the software and create your own live-cd with it.

Ah, so basically an alternative to the live CD. Though I would assume that a useful live *would* have the software installed.

It is a trust issue.  If you know a source for a live CD with the Bitcoin software already installed that can be trusted to NOT have put in other stuff...

I guess one option would be for some kind soul to put together a live CD but include scripts which download and install the bitcoin software onto a known-good(ish) live-cd so that some others can verify that it's a good CD. You can then choose to either create the CD yourself or trust that if there was something up, someone would have found it.

Great Info...

However, as I am not a wealthy man in bitcoins, I still use blockchain.info 's wallet, as it appears to be pretty secure to me.

If I however be wealthy in btc's, I will surely add more protection to my money.

Thanks.

I think the guide to being secure doesn't need to be complex at all, though I don't know if the required technologies are available to write such a simple guide.

For example I think that an offline computer can send money without being connected to the internet. You just use your signing keys(you must also know manually how much bitcoins you have beforehand, without having any blockchain around. Here you can use blockchain.info to check that up, advised to access it through Tor. Then since you know how much you have, you use your private key on that offline computer and sign a transaction. Then you transfer that transaction with a usb key storage to your main computer which may be virus and trojan+keylogger infested and just execute the transaction. Voila!

Though are these technologies available. We would need a very simple program, one that doesn't like need the latest version of Ubuntu, not the full fledged bitcoin-qt, except if it can work in offline mode and it can allow to send Bitcoins without needing an internet connection.

The above are maybe a bit of half-baked thoughts.

There may still be hope for the 1st decentralized cryptocurrency which is Bitcoin. How to approach different subjects is key to progress.

At the very least, I've avoided using online wallet services after reading about btc thefts.  So the argument about keeping those savings accounts on physical media and physically locked in a safe is not a bad one to make.

You are right, this whole thread is obsolete. There are two million + 1 ways to lose your bitcoins if you do encrypt your disk and create cold storage wallet and use regular client which you would never start. There's only one (ok two) passwords between you & your money on blockchain wallet, it is easy, secure (as long as your computer is secure), and convinient.

The only thing they need to do is to remove the builtin satoshi dice. I mean really, that's very distracting and dangerous. Have to keep money in an archived address to not waste them all while not sober.

That's exactly the question. How much do you trust them? Even if they're "smashing chaps", that doesn't preclude them from making a mistake. Of course, you may make a mistake too so how much do you trust yourself.

The security ultimately resides in access to the private key. If only you have access to it, that's about as secure as it's possible to get.

As long as you use the zerotrust method i.e. have the private keys yourself then they're fine.

But imo people shouldnt worry too much about bitcoin security - its far more secure than nearly all other forms of online transctions e.g. Paypal, moneybookers. The main problem is the flucuating exchange rate...

But this doesnt mean you can then use your bitcoin client on a comp which is used by other people who moght get it infected - still use a livecd.

The main problem though is that you have to trust the liveCD to not suddenly become infected...
