Moneychanger (Windows Builds) - Out of Date!

[da2ce7]

OUT OF DATE BUILDS - DO NOT USE!  -  Edit 30th October 2014


Open Transactions (commonly abbreviated OT) is a collection of tools that helps people create financial transactions.
Open Transactions is built around cryptographic messages.  Once can think it is as: ‘gpg-email for money’.

While Bitcoin provides a great way to transfer value between on identity to another; it doesn’t provide a good way to manage the ownership of real-things (such as hours worked, or the silver credits that your hold in your safe).

Moneychanger is our demonstration test-wallet (and if it becomes stable one could use it as their main wallet)… However for trivial amounts of value it should be ok.

If you are on a unix based system, the easiest way to get Open Transactions is to compile it yourself; please check-out our guides here:

Open Transaction isn't much use without digital assets:


Digital Assets:
Make sure your check out markm's thread for actual uses of OT:

Hope everyone likes it!  Please report bugs.

well we already have my first fix... updated the moneychanger builds.

Tomorow I'll put a list of the know issues on the OP.

[Stephen Gornick]

Is Open Transactions really a topic for Bitcoin "Alternative clients"?  Though I can't think of a more appropriate forum and I suppose technically the OT server could be considered a Bitcoin client?

[Nefario]

GLBSE will be adding asset export via OT in a few weeks, if that helps make it any more bitcoiny.

I lift my lamp beside the golden door!"

[da2ce7]

Ok... Updated the moneychanger builds again! Lets hope they have less issues this time!

 

[da2ce7]

Ok... been testing my releases on other PC's been finding a few issues...

1.  If you do not have Visual Studio 2010 SP1 with the Windows SDK 7.1 installed, you will not be able to run any of the 'Debug' builds.
2.  For release builds you need to install:


Microsoft Visual C++ 2010 SP1 Redistributable Package (x86)
http://www.microsoft.com/download/en/details.aspx?id=8328

and

Microsoft Visual C++ 2010 SP1 Redistributable Package (x64)
http://www.microsoft.com/download/en/details.aspx?id=13523

(I have no idea why microsoft dosn't ship them with windows, but anyway...)

3.  You needed to have OpenSSL installed... however, with my new builds I'll ship the OpenSSL DLL's with it.

[da2ce7]

New Builds.

On Windows, it's our responsibility to ship the redistributable package that our software is built for, the same way that you are planning to add OpenSSL DLLs to future builds.

At some point soon we will have a "RoboInstall" project (or similar tool) for creating the Windows install, and that project will have the OpenSSL DLLs, the Windows redistributables, etc. All of that will build into a single install .exe and when that time comes, there will probably be a lot more people "kicking the tires" so I'm happy if that comes together slowly because it's been giving us time to test, debug, and strengthen the software. The testers we already have, have definitely kept my hands full for the past couple of months.

Actually it is the OT java test client, Moneychanger, that could be considered a lite-weight bitcoin client/wallet ...

[becoin]

To sub or not to sub? That's the question. 

[da2ce7]

New OT Build for Windows.  Both Win32 and x64 this time!

I have included the OpenSSL DLL's this time to make things a bit easier.
Next build I'm going to be upgrading my OpenSSL packages to 1.0.1a

New Moneychanger Builds incoming soon also!

[da2ce7]

Updated the Moneychanger Build.

I've decided to include both the Old and New packages in one archive this time.

Updated the Moneychanger Build.

Have tried making a simple All-In-One package for those who want to just try-out moneychanger on windows:

Please give me your comments!

I just wanted to point out, this is the final step before having an actual Windows install program.

da2ce7's package doesn't actually install software, but it does come with all the necessary components pre-built, so you don't have to compile anything at all, just copy some DLLs and you are ready to run.

I understand this version comes with working builds of the OT localhost Server as well as the Moneychanger test GUI, meaning that you should be able to actually run the server right there on your Windows box, and then pop up the client, and play around with cheques, cash, etc.

It's a pretty momentous day! We're getting closer and closer to click-of-the-button installs. I hope that many of you are able to download the package and play around with it, so da2ce7 can get the feedback he needs to refine it.

I've been fudging around with this, but i have no idea what i need to tall moneychanger. What paths does it want? what is a password image file?
This is definitely nothing like an installer-ready build.
Doesn't work for me jet.

In the 'Java Paths' field you need to select where Java is going to look for the native libraries that contain all of the OT functions.

On Windows 32bit you should select:  ./Win32/Release/
On Windows 64bit you should select:  ./x64/Release/


The 'Password Image File' is a .png or .jpg file that you want stored in your OT local storage for your password image.  A password image is a file that loads up, unique to you, so you don't supply a password to the wrong dialogue by mistake.
Just select any Image file that you wish.

You will also need to copy the '.ot' directory to:  ./AppData/Roaming/  in the root of your user directory... Normal: C:\Users\(username)\


You will need to install the 32bit and 64bit version of java:

As well as the Microsoft Visual C++ 2010 SP1 Libaries:

x64: http://www.microsoft.com/download/en/details.aspx?id=13523

Ok I had everything right except for the password image file i think that one just didn't and still doesn't make much sense to me.
These are the errors I get:

com.moneychanger.ui.Load$LoadNativeDependenciesFailedException: java.lang.UnsatisfiedLinkError: C:\Users\psiborg\Downloads\Moneychanger-Win-24042012\moneychanger\Win32\Release\otlib.dll: The operating system cannot run %1
com.moneychanger.ui.Load$LoadFailedException: com.moneychanger.ui.Load$LoadNativeDependenciesFailedException: java.lang.UnsatisfiedLinkError: C:\Users\psiborg\Downloads\Moneychanger-Win-24042012\moneychanger\Win32\Release\otlib.dll: The operating system cannot run %1

Any ideas what's going on?

Imagine that you are performing a financial transaction.

For example, perhaps you are sending 100,000 grams of gold to Alice.

When you initiate such a transaction, a PASSWORD DIALOG will pop up on your screen. It might say, "Are you SURE you want to send 100,000 grams of gold to Alice? If so, enter your passphrase: "

NOW: How do you know FOR SURE that this is really your password dialog? How do you know it's not some FAKE DIALOG that a HACKER created, so he could TRICK you into entering your passphrase?

Because eventually when OT has a real install process, part of that process will force you to choose a PASSWORD IMAGE -- one of your own choosing. Perhaps you selected a picture of a goat that was dear to you in your childhood. Every time the passphrase dialog pops up, for you to enter your passphrase, that goat picture will appear on the dialog.

A hacker trying to impersonate your passphrase dialog will be very unlikely to guess the exact goat picture that you chose for yours, and thus will be unable to trick you into entering your passphrase into an imposter dialog. Without this security precaution, the hacker could make a fake dialog that would look correct to thousands of people.  But WITH this security precaution, the hacker would have to guess the individual password image used by each and every one of those thousands of people (and it's extremely unlikely that he could do that...) When his fake dialog pops up, any near-victim would immediately see that it's the wrong dialog, since it does not feature the unique password image that person chose when he first installed OT.

I hope that clears it up.  I'm sure da2ce7 will contact you soon to help figure out the issue you are having.
