Hello. After extensive use, I have a few questions about Electrum:

- Regarding Electrum addresses with asterisk under "Tx" column. Why have some of these addresses seen previous use (even before I generated the wallet)?
- Can the Electrum seed phrase program be modified to generate a 256 bit seed phrase? Can this be made a cmdline option, e.g. --strength [128,256]? If not, would a fork be possible?

I can handle lots of 12 word phrases easily; I want more security. I like Electrum, but I'm concerned about 128 bit security and also how certain addresses (with asterisks) have seen previous use according to blockchain.info. Please explain how this is possible. 128 bit seed phrase is ok, but 256 bit option would put Electrum over the top for me.

I do not think there is a serious reason to use 256 bits of entropy. (you might be confused because of RSA, for which a 128 bits key is too short. we're not talking about the same thing here)

if the addresses you generate have been previously used, it means that you are reusing a wallet that you already generated before, or that there is a serious security issue with Electrum. Switch to a full server and you'll recover your full history, not just the asterisks. if you believe this is the case, can you PM me the master public key?

A basic question here, is the electrum wallet.dat the exact same as the satoshi wallet.dat?

electrum supports arbitrary wallet filenames - you can easily maintain multiple wallets.

The internal structure is entirely different.

Electrum in a deterministic wallet - all addresses you ever need or will use are generated by a pretetermined pseudo random sequence. bitcoin-qt generates completely unrelated random keys as needed. The difference being that it's idiot simple to backup an electrum wallet by recording the initial seed value. the bitcoin-qt wallet.dat must be physically backed up ever 100 or so transactions

Is the update notification working as it should?
I had to click the empty space to get the notification, and it is also wrong.

Haha this should _not_ have happened. I will check out what I did wrong there

Edit:

On OSX that little shadow effect is not shown so I had no idea there was something clickable there. When there is a new version a label should appear there. I will try to remove the empty space itself when no update is available.

Edit 2:

Pushed a possible fix to git master. If anybody on windows could verify the button is now not appearing anymore that would be great

The button is not there anymore, but there's a little indentation error at line 1265 of gui_qt. Just add one more space to fix it

Code:

if (int(qtVersion[0]) >= 4 and int(qtVersion[2]) >= 7):

IndentationError: expected an indented block

I pushed a fix for the indentation error.

If you ignore all versions you will never receive the message again. If you don't want this to happen just use "ignore this version".

I support freedom of choice

ok

What happen if the user clicks the "Ignore all version" button?
How can the user reactivate the notification?
Can you add an option on settings to turn on/off update-notification?

version 1.6.2 was released today.

it contains bugfixes, and a gui notification of further releases.
also, the spanish translation is complete.
localization is now available with the osX builds

To get translations working on Windows, users can download the .zip file from http://electrum.org/download.html to extract the 'locale' folder and copy it to 'C:\Program Files\Electrum' (if you used the Windows Installer) or simply place the 'locale' folder in the same location as the Standalone Executable version of Electrum.

Is there any important bugfix, or is it still ok to use v1.6.1 ?

no critical bugfix in that release.
however, if you encounter a bug, please upgrade to the most recent version before you report it.

I need some immediate help please. I downloaded Electrum 1.6.1 for Windows yesterday, had money sent to one of my receiving addresses but it hasn't shown up in my wallet yet. The transaction has 49 confirmations as of this posting https://blockchain.info/address/1FJb2KSq2GgrsWKLyGzwzWUUDp94H7KZ6C but it's still not available in my wallet.. HELP!!

EDIT: Nevermind, I just reconnected and it's showing up

sorry about that. we have had some server bugs recently.
I believed the bugs are now all fixed in the repo, but it will take some time until servers get updated

Has anyone tried to get Electrum working on the One Laptop per child laptops?

What OS do they use?

They use Sugar, which is based on Fedora. I was trying to get it running on VirtualBox but as I'm a novice I got stuck on some dependency issues. Since then I've just been too busy to give it an honest chance.
