IMHO the safest possible bitcoin "wallet" would be #1 offline computer with open source OS #2 deck of cards [1] or other form of sufficient entropy #3 generate ECDSA key with the libary/tools the OS brings (use #2 for entropy) #4 generate your address [2] #5 encrypt everything #6 never use the machine for anything else, unless you want to spend the coins Security level: tin foil hat.

While it makes little difference for an offline machine, if you are concerned about security you should not use an OS that is no longer supported by the developers.

Only conceivable problem I see is when you actually want to spend your hyper-secured coins. You don't have Qt + Armory/Electrum to sign transactions offline (in this scenario) so you have to import the private key onto an online computer at some point which may be dangerous unless you spend the outputs instantly (although this is quite unlikely). Given this, I'd probably still say that you'd be better off just downloading Qt and Armory and making sure they've been GPG signed and match both sha1 and md5 checksums. Then copy them to a formatted USB and onto an offline computer. Title: Re: Impossible to hack bitcoin wallet help! Post by: nuno12345 on July 26, 2014, 02:02:59 PM #1 Get an old HDD an old pen drive and a brand new pen drive
#2 Copy bitcoin-qt to the old pen drive #3 Install windows on the HDD, this windows should never see the internet #4 Copy bitcoin-qt from the old pen drive to the new windows, after copying remove the pen drive #5 Open bitcoin-qt and generate a new address/privkey #6 Insert the new pen drive into the computer and copy wallet.dat to it #7 Remove new pen drive and format the HDD The only downsides on this is that you are still vulnerable to physical hacks and a remote possibility the old pen drive could have a virus that infects the new windows then infects the new pen drive, you will still be safe until you want to spend the coins, if this happens you can still sync bitcoin, disconnect the computer from internet insert new pen drive, sign an offline transaction and broadcast it trough blockchain on another computer Any way to not be vulnerable to physical attacks without using a password to encrypt wallet.dat?

One could spend the outputs instantly and use a newly generated (same machine, its there allready, so why not use it again) address for the change or rest. I was merely suggesting this as a solution since OP asked for the "safest" wallet. :P Title: Re: Impossible to hack bitcoin wallet help! Post by: gadman2 on July 26, 2014, 03:08:07 PM Coinbase vault.

Anyway it isn't very good to store it in a third larty wallet. Our control over it is very limited. Kindly, MZ Title: Re: Impossible to hack bitcoin wallet help!

Post by: screwUdriver on July 26, 2014, 06:16:57 PM I think the most secure way to keep your bitcoin safe is to make it so as few people as possible know that you own bitcoins. They will keep you from being subjected from most attacks

Most viruses only can do very limited tasks on your computer. Very few of them will search your computer and report back their findings. Title: Re: Impossible to hack bitcoin wallet help!

Other than just backing up your wallet on a couple different devices (another HDD, USB flash drives, 360KB floppy, w/e), I agree... except every step that bitcoin takes towards being 'mainstream' you'll get people that are less and less tech savvy/computer knowledgeable in general. God knows how much crap they have on their computers already from clicking on random Facebook pictures. ... and then there's the whole thing about wireless, esp. in public areas.

Not on a personal computer, a potential big loss,"choose a virtual treasure hoard in bitcoin storage sites as special protection systems available there. online wallet is much safer and reduce the risk of viruses. bitcoin wallet was just a number and cryptographic code. I use coinbase and blockchain for me because bitcoin depositary has its own system that can protect against viruses bitcoin, Once logged in the user is given blockchain usually hidden typer and password. Thus, there is only one risk that could make a bitcoin is lost at the two sites. "Well if we forget the password account in blockchain yes we lost bitcoinnya. Usually when in the existing e-mail recovery, if at blockchain no. Forgot password or hidden typer so exhausted already, let's just lost,. using different accounts on two sites. It means having two purses online to protect the currency and not have to worry about virus attacks. Title: Re: Impossible to hack bitcoin wallet help!

What about when you want to send the BTC? You have to connect to internet. Just transfer it to the USB and go to a clean Linux computer. You aren't get infected for just turning on your internet. Your private key would also not be exposed. You can always reset your computer every time when you send the transaction if you are really that scared. |
