Deleting the config file fixed it for me too. I couldn't imagine any beginner or even some novice users figuring this bug out because gui users will see a silent failure.

I am a Ubuntu beginner and having the same issue...at the risk of sounding stupid, where do I find the config file to delete?

Many thanks

It's in a hidden folder in your home directory. It has a name that begins with a dot : ~/.electrum

Here's a guide for various platforms:

Regarding 2. there is such thing as van eck phreaking:

http://en.wikipedia.org/wiki/Van_Eck_phreaking

He wants only unused addresses. listaddresses will show all main account addresses including used ones.

Edit:
I think you have to combine listaddresses with getaddresshistory. Loop over the output of listaddresses and then use getaddresshistory on each of them. If getaddresshistory returns empty then that's an unused address.

For stuff like this I prefer the command line rather than the elecrum console:

Code:

electrum listaddresses
electrum getaddresshistory 1BitcoinEaterAddressDontSendf59kuE

Electrum spawns a daemon process when you use the command line so multiple requests are more efficient. Still, getaddresshistory takes a few seconds per address so perhaps there is a more efficient way?

i am using wireless.. so i just right click disable wifi ..

so u mean should be ok if i dual boot... windows = online and unbutu = offline.. even my windows have virus will they run to the unbuntu to collect the files and sent back to windows via the internet thru the hacker?

It's possible but unlikely. Malware is usually targeted at a large number of people. So windows malware is windows only. You would have to be targeted specifically with custom malware that can read ext4 partitions.

Try this:

https://bitcointalk.org/index.php?topic=594733.msg6552620#msg6552620

Also try deleting the config file in that directory as well.

Click on the red icon on the bottom right and change to another electrum server. Note that the first time you run electrum on a new system, or operating system user account, it downloads the blockchain headers and that can take a few minutes.

anyway is there anymore commands lines other then the gap limit?

Using your operating system's command line (not electrum console) you can run a lot of commands. On windows this is known as the command prompt. On MacOSx I think it is the terminal app and on other *nix based operating systems it is the shell. Run the following in the shell and you'll see a list of commands:

Code:

electrum help

For command specific help type something like this

Code:

electrum help signmessage

Indeed, your private keys on Electrum are not at risk of being viewed by nodes. Your public keys, however, are. It is for this reason that it is said that Electrum is not ideal for those wanting a full level of privacy.

I think you mean address not public key. An address is a hash plus checksum of the public key. The public key itself is exposed only when you spend money from an address. That transaction gets broadcast to all the nodes and once it is confirmed it becomes a part of the blockchain.

I`m trying to pick either Multibit or Electrum.

Anyone using these, tell me the difference or which ones more user appeal.

Thanks!

Edit: I use a Mac

I personally use multibit. I find it to be very user friendly and easy to use.

My concern with Electrum is that your keys are stored on the server, making it not only possible for your keys/wallet to be hacked but also opening the possibility that you lose your seed (and your coins).

Electrum stores the seed in a wallet on your computer. Address specific private keys are deterministically generated from the seed at runtime. The private keys or seed are not stored on an electrum server. Electrum servers are queried for transaction details. They are sent your bitcoin addresses only. There are many electrum servers and they are all run by volunteers. They are funded solely by donations.

It doesn't look like Electrum is going to be adopting that word list:

https://bitcointalk.org/index.php?topic=623606.0

But other parts of that spec are being used. Like the mnemonic to seed function:

https://github.com/spesmilo/electrum/blob/31226b8a34c92b3e6c71cf4fab7c56bf73fe54e0/lib/bitcoin.py#L116

I like to think we'd be able to use numeric bip32 private keys from other software in electrum. Or install watch only wallets using extended public keys generated offline.

Add the --pre switch:

Code:

pip install --pre Elecrum-$ELECTRUM_VERSION.tar.gz

You need this for slowaes in newer versions of pip.

deseed creates a wallet file with the extension .seedless. What happens when you run it?

deseed does nothing to imported addresses.

Yes it does. I just tried it and it works. Import private key in offline wallet. Then run deseed to create watch only wallet. No manual copy pasting required. Also please see the quote in the OP from thomasv.

Code:

electrum deseed #default wallet
electrum -w /path/to/wallet/file deseed #other wallet

If the above doesn't work then what version electrum are you using?

edit: I just read your post again. You're not supposed to run it in the electrum console. You are supposed to run it on the command line i.e. command prompt on windows, shell on *nix.

deseed creates a wallet file with the extension .seedless. What happens when you run it?

What do you mean when you say a very small amount? I would think with all the security minded bitcoin owners there would be millions and millions of different bitcoin addresses.

Heh heh. I think you are being sarcastic and if you are I totally agree. Most people reuse addresses. Usually it's just one address that they use for everything.

Relevant chart:

https://blockchain.info/charts/n-unique-addresses

If someone has the total figure then I'd like to see that too. I vaguely recall somebody mentioning it on the forums and it was a very small amount. Most people just reuse addresses.

I know this isn't 100% secure or anything, but realistically is this a reasonable course of action to secure some coins?

1. USB flash drive of Linux Mint or Ubuntu

2. While connected through direct LAN cable internet go download Electrum.

3. Create wallet and write down seed on paper(double, triple check seed ect.)

4. Write down receiving address from wallet.

5. Shutdown computer and send bitcoins from non secure source to the receiving address that was written down.

How does that sound as far as a decent way to have some coins secured? If I need to access them I can boot up from the USB flash and restore the wallet from its seed.

Save the master public key to a file and use that to create a watch only wallet for your online system. This will give you unlimited addresses and offline spending capabilities i.e. a proper offline wallet.

offline pc being your PC booted off a live disc. Online being it booted of your regular OS.
