Is it possible to use electrum in python(or another language?) to query the balance of addresses other then one that is found in the wallet(aka query the balance of an address I don't own)

[highlevelminer]

I think this project is a great idea.

A pre encrypted wallet will provide an extra layer of security for savvy bitcoin users and the fact that it doesn't have to download the block chain will allow for faster and more efficient usage.

In comparison my bitcoin.com wallet is still currently synchronizing with the network which shows the need for a more efficient client.

I look forward to hearing about future development of this project.

Code:

$ electrum -b addresses
Traceback (most recent call last):
  File "/home/anorber/bin/electrum", line 291, in <module>
    if item['is_in']:  ni += 1
KeyError: 'is_in'

electrum.bitcoins.sk node is not updating confirmations for me while program is open. I have to close it and open it again to get updates.

ecdsa.org node updates 1st and sometimes 2nd confirmation automatically and then it also stops.

Any idea?  I use flatfly's 0.43d build. I've tried tcp and http options.

I had to reboot ecdsa.org this morning. it should be fine now

Hello,

I just released version 0.44

this new release is a mandatory protocol update.
you will need to upgrade your client in order to use Electrum;
older clients will no longer receive notifications, and may experience connection problems.

if you cannot upgrade your client, please visit your settings and select the native protocol; it will remain supported for a while.

Code:

$ electrum -b addresses
Traceback (most recent call last):
  File "/home/anorber/bin/electrum", line 291, in <module>
    if item['is_in']:  ni += 1
KeyError: 'is_in'

thanks for reporting that. I just commited a fix to the repo

sure. in a terminal, type:

Code:

watch_address <your address>

(this post was edited in order to reflect changes occuring in version 0.45)

Code:

$ electrum -b addresses
Traceback (most recent call last):
  File "/home/anorber/bin/electrum", line 291, in <module>
    if item['is_in']:  ni += 1
KeyError: 'is_in'

Thanks for fixing it!

[ThomasV]

version  0.45 is released!

new features:
* the Qt and Android clients can generate and read QR codes that contain a requested amount.
* The Qt client can save QR codes to a file.
* A new script, watch_address, is provided: it displays the balance of any address, and gets notified everytime a transaction occurs. It replaces the 'electrum balance' command.

Still no luck for me, no new confirmations while program is open. I opened second client after an hour and it already had 6 confirmations (see pic).

Also... a mini request: could you add ".0" for integer numbers under "Amount" tab? It looks a little bit strange the way it is now.



Cheers!

oh, I think that I know what's wrong here; thanks for the pic!
this is caused by the new stratum protocol: the client cannot detect when the link is down, because it does not poll anymore.
I believe the best way to fix this is to add a 'ping' message sent by the client.

yes, I can do that, but I am not sure if it really makes sense... are there other people who would want it?

I couldnt care less but since were on the issue eight zeros would make more sense then just one zero.

[flatfly]

8 zeroes would be a lot of clutter... How about 2 zeroes, like the official client (and almost all ledger / accounting software in the world)? So 0 BTC would be shown as "0.00"

Example:

[minimalB]

If ThomasV decides to go with 2 decimals, then 2 decimals should be minimum for all values (like in official client).

For example "2.5" is displayed as "2.50" in official client.



I agree with flatfly that 8 decimals would be to much. I guess 1 or 2 would work best.

Cheers!

[marcus_of_augustus]

Well millibitcoins are already being used regularly in some places ... Ogrr, bitcoin advert clicks, etc ... so i'd say at least 3 decimal places.

[BTCurious]

The main thing bothering the original poster is the decimal point with nothing behind it. If we can't reach an agreement on the amount of decimals, then perhaps the decimal point should simply be removed in case of whole Bitcoins.

Make it an option?
Set decimals ( 0 - 8 | default: 2  ): [ ]

indeed, when nobody seems to agree on something, it has to be an option.
