[ANNOUNCE] Electrum - Lightweight Bitcoin Client

[flatfly]

Could you add an at-a-glance way to see the current block number -- perhaps in the lower right corner?

You mean, something like this?


I have made a little patch for it and am currently fine-tuning it.
The patch is ready. If some find it useful and want to test it out, just let me know and I will post it.
(It's NOT included in my releases at this time.)

EDIT: Added a little hyperlink to the BlockExplorer count, for a quick comparison.

PS: bear with me, I'm still a beginner with Python and Qt

Could you give me a patch or a diff, want to try to patch my OS X version

Sure! To try it out, just back up your copy of gui_qt.py and replace it with this one:
 http://dre.tx0.org/gui_qt.py  (file size should be 53791 bytes)

Hopefully it should be OK on a Mac too, let us know

Thanks, seems to work fine, I hope this gets added to master.



It's not as pretty as on Windows but it will have to do

Thanks for the feedback!
If ThomasV decides to merge it, it's just 4 lines of code.

What key format does electrum use?  I just tried to import my wallet from blockchain.info using every format they provided, and none of them worked.  I keep getting an "unsupported key format message".  Furthermore, why do I have to provide both the address and private key?  Shouldn't the client be able to compute the address from the private key?

Uncompressed, WIF (starts with 5), the command is:

electrum import address:privkey

Where address and privkey are your actual pair.

[Topazan]

Thanks, finally got it to work.

Is there a program that converts between different formats?  Or at least a set of algorithms?

I like brainwallet.org -- you can run it off the site to see what it can do, or run it offline by downloading the zip.

bitaddress.org can also do some tricks with its Wallet Details tab. Like brainwallet.org, you can download the HTML and run it offline to be secure.

Sorry, you can try again now. Let me know if it works for you.

Tuxuvant : did you follow my Install instructions for Fedora posted earlier in the thread https://bitcointalk.org/index.php?topic=50936.msg948023#msg948023

Would somebody mind posting them on the wiki or with the source or something for Fedora and other RH derivative users?

[Tuxavant]

I did not (but might).. I've just been using the install commandline from the linux download option at ecdsa.org.

Yeah, it's a little generous to call it a "linux" download .... Debian-Ubuntu is known to work, I don't know what else it has been tested on ...


Edit: all right I tested the

Code:

sudo pip-python install http://ecdsa.org/electrum/Electrum-0.59b.tar.gz#md5=4254bad432f44d61904b93917860069b

on FC15 and it works. Note however though I already had the "slowaes" and "ecdsa" packages installed from previous deps on electrum work. I also tested downloading the .tar.gz manually, unpacking and running

Code:

sudo python setup.py install

inside the unpacked dir and that works also, but again with previous caveat about existing deps.

So known to work on FC will be something like this:

Code:

#
# use yum-ex and get packages PyQt4 PyQt4-devel
# or on command line

$ sudo yum install PyQt4 PyQt4-devel

# separately do same for packages python-setuptools python-pip

$ sudo yum install python-setuptools python-pip

# Install python modules ecdsa slowaes (crypto stuff)

$ sudo easy_install ecdsa
$ sudo easy_install slowaes

$ sudo pip-python install http://ecdsa.org/electrum/Electrum-0.59b.tar.gz#md5=4254bad432f44d61904b93917860069b

Note how the dep. packages need to be installed first, rather relying on electrum to install them. Anyway it is not good practice to "sudo" a whole lot of unknown packages onto your OS !!

thanks. there are 6 instances of getpass in the file.
is there a reason why you want to patch only 2 of them?

[ThomasV]

new release: 0.60

changes:
 - updated list of default servers
 - the client will not display servers that have not upgraded to version 0.1.
 - two new languages: chinese and dutch
 - improved help messages (tachik0ma)

#1 I barely knew what the hell I was doing.

#2 That was the only place I could find that "bothered me" at the moment.

#3 I will search for the other 5 and patch those too.

#4 Father, I am sorry I dissapoint. lol

edit: #5 I can't count. 4 other patches coming.

I was able to test (with success) all patch conditions with the exception of mktx and payto.

why don't you define a unique getpass function, instead of repeating things six times?

[Tuxavant]

That's all the mojo-fu I have at the moment. But, challenge accepted. I'll give it a go when I have some time.
