[ANNOUNCE] Electrum - Lightweight Bitcoin Client

[NothinG]

I guess this is the straw that broke the camel's back. Upgrading this server to CentOS 6.2. Thanks for the knudge.

May I ask what version of CentOS you where using prior to the upgrade?

5.7

I think Centos 6 has python 2.6, so you still don't have 2.7.  At least it is better than 2.4 though.

Today, I've had a (tiny, for testing) transaction take more than 4 hours to get its 1st confirmation.
Then the 2nd confirmation came about 10 minutes afterwards, as usual.
Could the initial delay be due to the fact that the fee I paid was just 0.0001 ?  
Out of curiosity, I'd like to know how Electrum servers prioritize transactions...


The details are here:

That's exactly correct.  Only the first confirmation can be delayed because of insufficient fees.

Electrum servers do not prioritize transactions.
They simply broadcast your transaction to the Bitcoin network.
At that point, the time to get a confirmation depends on the fee you paid.

The long delay you experienced might be caused by the current traffic caused by the SatoshiDice frenzy.

[flatfly]

This SatoshiDice thing could turn out to be a VERY good thing for Electrum...
With the blockchain size now at almost 2GB and increasing faster than ever before,
I think there is a golden opportunity for many new users to try out Electrum. They
just to need to find out about it...

electrum is -><- close to being my offline wallet. Last night I just played with moving the seedless wallet to an online computer for syncing and back. Pretty darn awesome and easy to do.

Here's another feature request... once the wallet file gets sync'd, can the balance function be modified to display the "cached" balance if it detects no network connection?

[flatfly]

Another little issue: when several transactions are in a pending state, they get listed in a strange order (not chronologically, like previously confirmed transactions). Once they are confirmed, they remain in that order, which leads to strange balance values, including negative balances, when looking at the history. Could you have a look at this screenshot?  Look at the negative balances toward the bottom.

indeed, transactions that belong in the same block are not displayed chronologically.

yes, I guess I can add that.
in the mean time, note that it is possible to display the balance of your wallet wile offline, using the command line 'history':

Code:

electrum history

electrum history

Well crap, I need to get out and play more. That's perfect for my needs. Forget it then... Spend your time on some other awesome feature (hint: like a currency calculator, a better installation system for android).

Is there a way to extend the deterministic sequence of wallets to have more keys (without having to backup the wallet)?

it depends on what you need.


if you only occasionally need a few more keys, use the last address of your list each time you need to receive a payment;
when you receive that payment the wallet will generate 5 new keys (instead of just 1 if you use the first unused address of your list.)


if you systematically need more, you can change the gap_limit parameter in wallet.py
you will not have to backup the wallet, but when you restore it you'll need to remember the new value.
(the gap limit used to be a user preference, but I removed it from prefs for safety)

version 0.48 is released.
There is no new feature, only the install procedure was modified.
it is now possible to install Electrum with easy_install:

Code:

sudo easy_install http://ecdsa.org/electrum/Electrum-latest.tar.gz

[flatfly]

Are you sure about the Electrum module in 0.48? Shouldn't it be lib?

[ThomasV]

Are you sure about the Electrum module in 0.48? Shouldn't it be lib?

the 'lib' directory is installed as a python package with the name 'electrum'
I think you should be able to install it as a package in windows (run "python setup.py install" )

if you cannot do this, I guess you'll need to call 'lib'

Thanks, I will try that

Couldn't do it using setup.py (too many dependencies missing, no time to fix that now)
so I will just call lib for now...
