I have the C++ documentation ready and the source downloaded. Before I pick my way around and try to begin to slowly absorb this thing, any tips? Is there any actual documentation on the Bitcoin code itself?

We're fucked now! What next? The manual for Three Mile Island, and you're going to fix that? (Sorry, Harv. Couldn't help myself. Good luck with C++).  Wink

Oops! I may have misunderstood your post. I thought you were going to delve into the client. My bad!

There aren't a lot of comments, but it's a relatively small code base and most things are fairly self-explanatory.

I noticed in the development forum someone had already done what you are going to do, and also done some good writeups on the code. Don't have a link right here, but I'm sure you will find it.

  • Use the debugger to step through the code.  Makes it easier to see what's going on.
  • PyBtcEngine is a near-complete implementation which I am finding much easier to follow.
  • Documentation is sparse, but there's some on the wiki, and a thread called "overview of the Satoshi client", both of which can be pretty handy.  Browsing the source code history with a tool like gitk can also be informative, but it's a bit of a crapshoot.

If you haven't done C++ before then you might find the BitcoinJ java implementation easier to read.

I don't know how helpful it will be to you; but my (woefully incomplete) alternative bitcoin client is available at:

https://github.com/andyparkins/additup

I was trying to write clearer code than the satoshi client so perhaps it will help with understanding.

The protocol is there, and a broadcast block reciever.  But they are held in memory not written to disk.

I haven't looked at how much of 0.5 is in QT, but I'm somewhat familiar with QT myself. Any object that starts with a Q is likely to be a QT object, and QT's documentation is pretty good. Simply google the object type and you should come up with a page on Nokia/Trolltech's site that has all the details in it.

I only mention this since I think your major grievance was the UI, and I gather the 0.5 version's UI is QT-based.

Version 0.5 actually comes with two UIs.  There is a bitcoin.exe and a bitcoin-qt.exe.  Depending on whether you want the new QT UI or the legacy UI.

So he could still poke around in the non-QT based one if he doesn't want to deal with QT.
