Online label syncing plugin in Electrum 1.7

[Tachikoma]

LabElectrum

Starting with Electrum 1.7 there will be a plugin to sync your labels between multiple instances or installs of Electrum.

The syncing works in two parts.

• A webserver running on cloud-hosting service Heroku: labelectrum.herokuapp.com
• A plugin for Electrum.

Setting it up

If you want to help me test the plugin you can use it as follows. Go to the LabElectrum site and sign up for an account. The service does not require email confirmation  so feel free to improvise. Once signed up copy the API-key to your clipboard. Download the latest 1.7 release of Electrum and go to the plugins tab and enable the "Label Sync" plugin.



Enter your API-key key. If this is your first time using the plugin use the "Force upload" to sync all upload all your current labels. If your labels are already uploaded you can simply press "Done" and restart Electrum to retrieve them all from the server.

To test if it worked you can login to the LabElectrum site again and see if you see a wallet id and the amount of transactions you have uploaded.



Privacy

Now please note the following matters regarding your privacy:

• The unique identifier for your wallet is your master public key hashed.
• Your transactions, addresses and labels are send to the server in encrypted form.

Future plans

The ability to not only decrypt and view your labels online but also edit them.

I've updated the plugin and webservice to fully encrypt all data using AES.

Awesome work, this works great for me, It's absolutely brilliant for traders on the go (cash trades, etc). Can have electrum running on my laptop which means a really fast 'instant on' experience, but at the same time have everything sync perfectly with my PC back at home.

Glad you like it; there is still a bug somewhere that makes it so your labels and uploaded twice and the javascript decryption isn't fully solid yet; but hey. It does the job

Hi,
Thanks for great service. I have a question. How do I connect my Android Electrum client to the labeling sync service? I don't see any options to install a lable sync plugin on Android client.

[Tachikoma]

There is no plugin system in the Android version.

[slavix]

so no label syncing with android..

[Tachikoma]

Exactly.

I just want to be 110% sure about this - we're just syncing labels which can be used to make a record of what each transaction was and is for, for easier accounting.
Transactions are noted but these can't be abused in any way and private keys aren't transmitted.

Thus, the encryption is there for financial privacy.

Just want to be totally sure that this is what it is?

[Tachikoma]

You are correct; even in the worst case scenario that the database would be exposed there would be nothing in there that could be used even when decrypted; except perhaps your password if you re-use that somewhere.

Thanks for this plugin!
It's a pity there is no plugin system for the Android client.

[Tachikoma]

There is work being done on a native, non officially supported, Android client that will also support the label sync plugin.

just enabled this.  great feature.

I just enabled this plugin for the first time with my existing wallet using Electrum 1.9.5 portable. It did upload one single transaction label and stopped there. I tried the "force upload" button several times but nothing happened.

Any known issue? Maybe there's a problem with labels containing symbols? Like:

Thanks!

[Tachikoma]

I haven't checked those out. I will do some checks when I can find some time
