thats great man!
Keep up the good work, really looking forward to the version with wallet encryption.

Will you be adding some support for offline wallets you think ?

wanted to do some translation for you today but http://translate.multibit.org/project/multibit is not working.

Do you know of problems with the site?

I just tried http://translate.multibit.org/project/multibit and it worked ok.
It resolves directly to the crowdin.net site (under the covers) so maybe they were doing something with their servers (Sunday maintenance?)
Seems ok now.

RE: offline wallets.
I am not sure actually.
I will certainly be doing watch-only wallets (which have been supported in bitcoinj for a while).

I have a Raspberry Pi on order to see if I can run MultiBit directly on it (with practically no modification).
In which case I might suggest doing something like:
1) Create encrypted wallet using MultiBit on Raspberry Pi.
2) Create watch only wallet and copy it to your main machine.
3) Lock your Raspberry Pi in your safe.
4) You can use your watch only wallet on your main machine to receive tx and check balance.
5) When you want to do a spend, take out your Raspberry Pi, let it sync, fire off send, get the send confirmation, switch off, lock away again.

It is not offline signing as you are connecting the Raspberry Pi to the network. To get your private keys someone has to steal or hack your Raspberry Pi for the few minutes it is out of your safe and connected to the network.

Hi, I have a feature request.

1- Add on transactions tab a column showing what was the usd value of 1 bitcoin in the time someone sent me the coins.
If I'm a merchant that accept bitcoin I would like to record the value of bitcoin on each transaction. So I can choose to only sell it if bitcoin price is = or higher when I received it.

[jim618]

Hi Teste,

Thanks for your feature request.
I have been thinking about how best people can do their "Analytics" on their transaction data.

(Commercial companies always try to sell another software package called "Business Analytics" for the decision makers to take a bit more cash off them :-) )

Due to me pretty much being a one-man-band I cannot really do this properly so I think I will go down the route of exporting the raw data so that users can work on it.  There have been previous requests to export as CSV so I will probably support that. That way people can import it into Excel / Open Office Spreadsheet and slice and dice it to their heart's content.

You would have all the transaction data (including date of transaction and hence can do a rate lookup on whichever exchange rate you want to use).  Hopefully people will start sharing their solutions/ charts so that people will not have to do it from scratch.

I think that is the only practical way to do it - I know we had 2 or 3 people permanently on Analytics at my last place and we could never keep up with the requests for different data presentations.

The screen layout for "Change Password":

Hi!,

Just installed the lastest version and it seems a-ok, so thumbs up for that!

I was wondering: i once remarked that a "portable" option in the installer would be a great thing, you know so that the app can be installed on a usb stick.
It seems to me that the app is portable already, or does the normal install put files in other directories?

Thanks!

Roland.

[jim618]

Hi Roland,

Thanks for your feedback.

MultiBit is quite easy to run off a USB drive, you just have to copy a few files around. There is a 'how-to' here:
http://multibit.org/help_runFromUSBDrive.html

I would like to have a version that integrates smoothly with PortableApps.com as that is a very good environment for USB drives. I have looked at what it entails and it is various configuration files etc. It is a bit of work but would be worth doing I think.

If you are happy to move a few files around it does not take very long to set MultiBit up for a USB drive. In some of my tests I create a temporary directory, copy in a blockchain, create a multibit.properties, run the test with the 'MultiBit runtime' I just created, then throw it all away. It is that easy.

I have put an icon for the wallet type (i.e. encrypted, unencrypted) into the individual wallet panels:
Composite with wallet details shown and not shown:



As MultiBit understands more wallet types, there can be different icons (e.g. an eye for a watch only wallet). There are tooltips for all the icons.

Also I have removed the 'Type' row from the wallet details panel as it is redundant.


edit: twisties back.

[jim618]

When you are importing or exporting private keys on an encrypted wallet, you also need the wallet password so I have added it to the corresponding screens:

http://multibit.org/postImages/importKeysWithPassword.png

There are two passwords required (the wallet password and the password for the export file) but hopefully the labelling and different sections makes it reasonably clear.

edit: playing around with the icons

Wallet password added to spend confirm dialog:

I am getting excited!!!!

[jim618]

Thanks!

Note that this is all pure user interface work. The buttons click and everything but they they don't do much of anything yet.

There is still a fair amount of "down in the engine-room" work todo yet.

I understand... I do software development for a living, so I understand that there is WAY more work to do than looks like. 

But I love what I am seeing

Now if you click on the wallet type icons the appropriate help page opens:

There has been a flurry of translation work on MultiBit in the last week or so:

• Dutch. This is now at 94% of all texts (including the encrypted wallet ones!). Translators: damnek, grouver, Wim, dutchbrat, bitcoinspot, Marius van Voorden
• Danish has now been added to the target languages and started by D4CH
• Esperanto has also been added and has been started by Colin Dean

Thanks to all for their efforts.
I will do another MultiBit v0.4 build around the middle of next week. (I want to upgrade to bitcoinj 0.5.2 as well at the same time).


The encrypted wallet localisation phrases are now all on the http://translate.multibit.org site so please log on and translate some of your mother tongue. :-)

Can Multibit import a Satoshi client wallet?

If not, is there a plan to add this feature sometime?

[jim618]

Hi Mageant,

Not directly no.
If you export your Satoshi wallet keys then you can put them in a file and import them using 'Tools | Import Private Keys'. It imports the sipa key wallet format (the ones starting with 5) but not the compressed private keys.

I was not planning to add this feature no as it would be a lot of work for not that much extra gain.

[jim618]

Over the weekend I hooked up the UI work I have done to the code that actually does the encryption.
Now when you 'Add Password', 'Change Password', 'Remove Password' it actually encrypts/ decrypts the wallet.

Screenshot for change password (though it does not look very different)
http://multibit.org/postImages/changePassword.png

There is also more feedback to the user on whether the encrypt/ decrypt was successful or not.

There are various changes still to do (e.g. wallet persistence still not done) but I am going to swop back to the v0.4 branch and work on that for a few days now.
