Happy Halving Day Everybody !

Jim, can you edit out the quote in https://bitcointalk.org/index.php?topic=43616.msg1362963#msg1362963 please?
Problem was solved by downloading blockchain from Nov. 22 as you stated.

Removed as per your request.

I think I have done all the currency support / number localisation work. Screenshot:



It is quite easy to miss localising something on one of the screens/ warning dialogs so I will spend the next 2 or 3 days:
+ porting the code to the live branch (it is all in the encrypted wallets branch at the moment)
+ testing the various screens/ drag and drop/ bitcoin URI support

There should not be any new localisation terms added before the release - thanks for the localisation efforts everybody over the last couple of weeks. The help/ website will need updating but I can do that afterwards.

Assuming nothing too serious turns up in the testing I aim to get it out on Monday.

(Edit: and then the encrypted wallet beta with the currency support in should be a couple of days later)

Gary has started discussions with the lead dev of http://openexchangerates.org/ (Joss) to see if we can get some bitcoin to 'other fiat' cross rates.

On their FAQ they mention adding in bitcoin by 'the end of 2012' so they look bitcoin friendly.

hi jim, i tried to start the mac os multibit.app with the -testnet switch
i guess you know it does not work this way. what's the proper way to connect multibit to testnet, use testnet addresses and stuff, please?

the boring part:

Hi Binford 6100,

To use the testnet, there is an option that you put in the multibit.properties configuration file.

I see you are on a Mac, so I recommend doing the following:
1) Duplicate your multibit.app to, say, multibit-testnet.app
2) In Finder, do a right click and 'Show Package Contents'.
3) Navigate to: /Contents/Resources/Java
4) If you put a 'multibit.properties' file in the Java directory that install of multibit (only) will pick it up and use it. It effecively runs in local mode and does not use your user data area.
5) Create in TextPad a file called multibit.properties and save it to the Java directory.
6) In the file add the line:
      testOrProductionNetwork=test
(case sensitive)
7) Then when you open that install of multibit you will connect to the testnet and see something like:


A couple of things to note:
a) I almost never use the testnet so you might run into some gotchas - let me know if you do.
b) This is the 'old' testnet (with genesis hash 0000000224b1593e3ff16a0e3b61285bbc393a39f78c8aa48c456142671f7110)
There is also a newer testnet3 (with genesis hash 000000000933ea01ad0ee984209779baaec3ced90fa3f408719526f8d77f4943) that currently there is no switch for. If you need this I can add it in - just let me know.

jim, thanks a lot!
i followed your guide, well written and easy to follow and it worked as expected, just much much faster.
the reason is i'm promoting bitcoin to friends and want to give away test net coins so that they can play with them, loose them, get hands on experience w/o having to test with 1/100-1/1000 of btc or fear to loose more if using the real blockchain. testnet coins are still dirt cheap.
if i'll ever need the switch for testnet3 i'll let you know.
p.s. i also need a testnet client to verify the translations i work on : )

Hi PTSeller,

Sorry to say that if you have not managed to find the relevant private key after looking for a week (the private key to the address 1MfPk2Kifpv85zokzQWW3ZFjrw6tyguMWf I mean) then I doubt anyone else will be able to find it. Unfortunately without the private key there is no way to spend your BTC on that address so effectively it is lost.

:-(

Jim

hello Jim can you please tell me how does private key looks like ? i am new to BTC thing thank you !!

[jim618]

There is one private key for each bitcoin address listed in the 'Request tab'. These are the receiving addresses that people send bitcoin to.

If you have the receiving address/ bitcoin address in your wallet then you will have the private key in your wallet. You need the private key to spend your bitcoin which is why it is so important.

There is a little bit more in the multibit help here:
http://multibit.org/v0.5/help_whatIsAPrivateKey.html

i have many files in hard disk how does it looks like mate ?

[jim618]

The MultiBit/bitcoinj private keys are 32 bytes long and stored in the wallets in binary format.
Realistically you need a program to parse the recent (protobuf) wallets to extract them. If you look at it in a hex editor it is all just bytes.

In theory the wallets can be parsed using a variety of programming languages but to my knowledge there is only MultiBit/ bitcoinj that can read them.

good news

Hello

i just formated my system installed my multibit again but when i replaced my wallet with original one ( the backup one ) its gives me error


Error - > Could not load the wallet file "C:\Users\---------\AppData\Roaming\MultiBit\multibit.wallet".
The error message was "java.io.FileNotFoundException C:\Users\--------\AppData\Roaming\MultiBit\multibit.wallet (The system cannot find the path specified)"

[jim618]

That is the file path of the default wallet name.
I would check things like: is the file there ?, are you logged on as the same user ? etc.
You can rename your backup wallet file and open it directly if you want to.

[jim618]

There is a new live release of MultiBit at:

multibit.org


Version 0.4.15

Improvements
+ Fiat currency support (as outlined in the last few pages of this thread)
+ I18n refresh
+ Mac now uses command-c and v for cut and paste


Scan of release checklist


The encrypted wallets version with all the currency support should be out in a couple of days.

[jim618]

Thanks for the donations to the multibit.org donations address in November and December !
They are always appreciated.
:-)

[jim618]

I have tweaked the BTC amount so that it is aligned on the decimal point as it is easier to read.
Screenshot:



Also, the Amount columns were not sorting correctly (it was ignoring the amount sign). This is now fixed.

These changes will go in the next encrypted wallet release. They are 'nice to haves' rather than urgent bug fixes so I will wait and bundle them into the next live release.

If you spot any inconsistencies with things like the number parsing, currency support or translations please post here. I have gone through the basic combinations but of course there are lots of currencies x languages now.

[slush]

Jim, I tested latest release, monetary calculations looks very nice :-).

However I think I've found one bug, wallets (left columns) don't adapt column wide, so wallet balances are hidden under right column...



Hopefully there won't be too many bugs in this release, so you will focus to BIP32 wallets ;-).
