I have installed Electrum 2.8.2 on Windows 10.

When I try to sign a message/transaction with a HW1 wallet (btchip) I get the error message "No module named websocket".

On Ubuntu I fixed this by installing the package "python-websocket".

How can I resolve this issue on Windows?


I have also created a github issue:
https://github.com/spesmilo/electrum/issues/2433

I have installed electrum server according to the guide at https://github.com/spesmilo/electrum-server/blob/master/HOWTO.md
I downloaded electrum-fulltree-10000-2015-12-29.tar.gz and checked the md5sum.
bitcoind is running.

When I start electrum server I get the following

Code:

[30/12/2015-15:06:38] Starting Electrum server on localhost

But it will not continue.

If I execute any ohter electrum-server command (e.g. stop, status, getinfo) then electrum will use 100% CPU but will be stuck.
The only way to stop it is to kill the process.

If I start it again I see the following in the log

Code:

[30/12/2015-15:40:11] Starting Electrum server on localhost

Any ideas?
Thanks.

I'm bought a Ledger Wallet and like the idea to have multiple accounts from the master node.
I'm also a long time Electrum user and would prefer to continue to work with this wallet.

From what I understand Electrum only uses the first/default account in the tree. (e.g. m/0/c/i)
Is there a way to retrieve keys of additional accounts? (e.g. /m/a/c/i)

Of course usable and grouped in the GUI would be best but it would also help if I could use them through the command line.

I was using the LabelSync plugin in 1.x versions.
Since I have upgraded to 2.x I can't enter any account info anymore.
Currently I'm running 2.5.2.

When choosing Settings I only get the Force upload and Force download buttons.
But no way to enter the decryption key and the others settings one had to enter in previous versions.

Anyone got this plugin working in the latest electrum version?

Hi

I'm looking into creating a rig using FGPAs.
To control them I would like to use a Beagleboard-xM or Pandaboard ES.

The Beagleboard-xM has a 1GHz ARM Cortex-A8.
The PandaBoard ES has a Dual-core ARM Cortex-A9 MPCore with Symmetric Multiprocessing (SMP) at 1.2 GHz each.

Has somebody used these boards?
How many FGPAs do you think it will able to manage?

Thanks.

Hi

I'm trying to set up a linux based mining rig based on FGPA.
I'm interested in using a Beagleboard to control the FGPAs.

The question is how much RAM do I need to run several instances of a mining software like diablo, phoenix, etc.
Can somebody with a linux mining rig share some numbers?

Thanks!

Hi

Is it possible to choose which Bitcoins will be send using Bitcoin-Qt or bitcoind?
E.g. I have 3 addresses in my wallet
A has 1 BTC
B has 2 BTC
C has 1 BTC

I now want to send 1.5 BTC without using the BTCs that are in A or C.

Thanks

Edit: typo I have 2 addresses...

I have a wallet.dat which generated a Bitcoin address.
I successfully sent Bitcoins to this address.

Before using the wallet.dat I stored it in a save location.

If I now use the stored wallet.dat my Balance is 0.00 but if I move the current wallet.dat back to the bitcoin app folder my Balance is ok.

Is it possible to retrieve the new balance with the previously stored wallet or do I have to backup my wallet every time a change in Balance has been made?
