MultiBit

Are we ever going to see sendmany support? That would be nice.

[jim618]

Yes I will be at the London conference.
I have a technical slot to go over what I have been doing on MultiBit over the summer.

RE: sendmany - I would like to beef up the send options to include sendmany and choosing change addresses etc but I must admit I would like to first get in:
 + encryption out the door (useful for everyone)
 + support for displaying fiat amounts and then switching it around so that you enter in fiat and see the bitcoin amount (useful for 'fiat people' and merchants)
 + would really like to get in server side bloom filters if and when that becomes live. (should see big speedups and it is an enabler for other things).

Oh well - it is a fact of life that our imaginations can run a 1000 times quicker than our ability to implement things.

ok great,

when are you scheduled?

Roland.

[jim618]

Hi Roland,

I presume from your question that you are going too so we can meet up !

I do not think the schedule is fixed yet - there are two rooms they have for talks apparently so I imagine there is a bit of juggling to do.

My talk will be mainly going over what has been done over the summer, demo and a look at what work is planned next.

I think it is going to be a really interesting conference as Bitcoin is popping up all over.

yeah im really psyched too

im planning to make my little list of bitcoin-questions, cause theres still a lot of stuff that i dont understand.

There is a new live release of MultiBit at:

http://multibit.org

Version 0.4.8

Enhancements:
+  I18n update. Hebrew added as target language. Lots of new texts including fr:95%, ja:44%, he:24%



Scan of release checklist


This release is mainly because there has been quite a lot of localisation work over the last week that I wanted to get out. Thanks to everyone who has spent time translating source text.

[jim618]

Thanks to the localisation effort this week translators !
French is now at 100%.

Also, I could not resist posting some links of screenshots of MultiBit in Asian languages:

Japanese

and

Korean


They are both at 67% translated as I type. (The Japanese screenshot is from a couple of days ago so is actually more done than shown).

Ideographic languages are certainly more space efficient than our rather long and rambling Roman character transliterations.

Here is the MultiBit translation site

I've totally failed on the translation duties. I translated the wallet to Finnish once and afterwards I've just been so busy with other stuff. But this is one of my favorite wallets so I will get the Finnish translation up-to-date asap.

[jim618]

Hi Technomage,

Thanks for the help!

At the moment bitcoin is still quite English centric and geeky but the language work is all about making it easy for new people to start using bitcoin. Bitcoin is confusing enough for new starters so you want the text they are reading to be their mother tongue.

I am hoping other projects will recycle the MultiBit translation work, as the text probably covers 80% of a typical bitcoin wallet's words.

There is a nice appearance of MultiBit in this video that Tony Gallippi@bitpay has made for Max Keiser's PirateMyFilm.com website:

Good one Tony!

Hi, Hopefully this is the right place to post problems with Multibit! My bitcoins are stuck, I can't spend them!! The transaction when the bitcoins were transferred shows up as confirmed with a tick, but my available balance shows up as 0, what is going on? Some minor transactions are being shown as waiting to be confirmed but they are small amounts.

Blockchain.info shows 8 confirmations already with that amount. HElp!

Update: Ok, after a long while I figured out that after sending, say a very small amount, the whole balance is locked down until that transaction I just sent gets at least 1 confirmation! Is this supposed to happen? Never happened to me with the other clients???

[jim618]

Yes - it is most likely this:
http://multibit.org/help_availableToSpend.html

It does not appear in other clients that have the whole blockchain (or talk to a server with the whole blockchain).
Because MultiBit does not have the whole blockchain to check against, it has to wait until the transactions you send appear in a block before it is sure that everything worked ok.

If you have an unspent output of, say 50 BTC even a small spend can make that unavailable to spend. e.g. the transaction might be:

You spend: 0.01 BTC to address 1aaa

The transaction consumes your 50 BTC transaction output, sending 0.01 BTC to 1aaa and 49.99 BTC back to one of your addresses as change. Until the transaction appears on the blockchain MultiBit will not you spend the 49.99 BTC.

It is mainly in there because otherwise you can get into complicated and confusing situations such as:

1) first transaction gets sent but never confirms (say fee is too low)
2) a second transaction that uses the change from transaction 1 then also does not confirm because transaction 1 does not.
3) the user that received transaction 2 may have a client that allows them to spend unconfirmed BTC, in which case THEIR recipient gets BTC that is dependent on the very first of your transactions confirming.

This all gets too confusing hence the restriction in MultiBit.

I have put in the ability to change the Look and Feel. You can use this to effectively skin MultiBit.

In the 'Preferences' tab there is now an 'Appearance' section with a 'Look and Feel' combo box:



Here is an example - this is the Nimbus Look and Feel with the font set to Verdana.



So far I am just listing the available Look and Feel that are available on the system but if there is a particularly nice one I like I might bundle it in.

This code is currently in test but I will copy it back to the live branch and put it in the next live release.
This code will appear in the next live release.

[jim618]

For Arabic, Hebrew and Persian/Farsi users I have been working on right-to-left layouts.
Currently all three of these languages are between 20 and 25% translated.

There is still some work to do, but here is a screenshot of MultiBit set to Hebrew:



You have to use your imagination a bit as the English is rendered left-to-right but when translated to Hebrew it will be rendered right-to-left. This work will appear in the next live release.

I like the differences between a languages.
good work Jimi

[jim618]

Thanks !

Lots of languages in the world but everyone can use Bitcoin.

:-)

[tpantlik]

Hi, thanks for a good work on great client!

There is a lot of languages available but there isn't Czech translation yet. Can I work on that?

[jim618]

Thanks!

Sure - I will add Czech as a target language.
I will add it in tonight.
