Anyone managed to get this working on BSD or whatever it is that macs use?

if your on lion you need to use Xcode and inside of xcode install the command line tools to get it working
and also use homebrew to install dependencies macports doesn't work as well for me at least.

Great! Thanks for that. I'm on snow leopard and have installed compiling tools, so I'll give it a go.

actually I forgot you need to update your gcc to gcc 4.5
so do...

Code:

% brew tap homebrew/versions
% brew install gcc45

The fix is to remove the -m64 flag from the Makefile. Should I do a pull request?

I'll probably try implementing that in a bit, but I need to finish decoding the scripts first Sad

I'll have to read your explanation about the algorithm you describe when my
mind is a little more alert than right now (4am here).

However, for the script decoding part, I would suggest looking at my code,
in file util.cpp, routing solveOutputScript and showScript. They're very simple
and pretty much self-contained (unlike the satoshi client code which has lots
of layers of abstraction and makes things a tad hard to follow linearly).

Cool, will do. I'm doing it in a completely different language (I dare not say which, lest people judge me! Huh

), but having some nicely written code to look at will be a great help, thanks.

I haven't had a chance to look at your code yet, but do you use Tarjan's union-find to compute the "wallet-sets"? I've been meaning to write a tool that does that for a while.

Edit: oh, you're using boost's connected_components. I think they use union-find for incremental_components.

Yes I do because I build the entire graph in the first place.

Not sure what algorithm they use in there.

Also, given that I build the whole graph, not sure why using
TUFA has any advantage over a dumb [D|B]FS mark and sweep ...

Yeah, it doesn't. I wasn't planning on maintaining the entire graph, so can get away with it.

Turns out that the graph will grow so fat at some point that it might
very well be necessary to move to some sort of incremental data
structure ... that being said, since there is no way to know that two
disjoin subsets will or won't merge until the very last tx in the chain,
I don't think it's possible to get away with _not_ building the whole
graph in the first place.

Well, I haven't tried implementing it yet, but my thinking was that the union-find structure represents just as much of the graph as we need. We basically have an equivalence of "has been used as an input in the same transaction as" and we're building equivalence classes.

So basically, you make a pass over the data building up an associative map structure from each address to something your union-find algorithm knows how to deal with (I'm language-agnostic Wink

). As you process transactions in the block building these things up, you make sure to call union on your union-find structure to join classes together if you see them as inputs to the same transaction. This is linear in the number of inputs, not quadratic, because the structure knows what's already in the class. Once you've made your pass over the blockchain, you're left with a big map containing all input addresses ever seen and your union-find structure. Now all you need to do is traverse your map of addresses and look up (using find to find a representative element of your equivalence class) which set each element is in, and group on that. The resulting sets should be your connected components. You could then make your map from addresses point to the set it belongs to for easy lookups, or do whatever.

If I'm not spouting nonsense, that would allow us to run the set-building in O(n * alpha(n)) time, where n is the total number of inputs to all transactions. You'd use O(total unique input addresses) space for it, and it should have fairly low constant factors.

I'll probably try implementing that in a bit, but I need to finish decoding the scripts first Sad

1) in cb/simpleStats.cpp i simply changed

Code:

typedef unsigned int uint128_t __attribute__((mode(TI)));

to

Code:

 typedef unsigned int uint128_t;

and 2)
in Makefile changed "-m64" to "-m32"

my Slitaz Linux box has only 1280 Mb of RAM, so it's low performance is reasonable.

OK, now that's clear: what you want is a full dump of the blockchain in graph form.

So, as it is today, the code can't directly generate that, but it'd be a feature super simple
to add to the 'allBalances' callback since the code basically walks that exact graph to generate
the final balances.

That being said, this is going to be a *huge* dump. To get an idea, here's the current
blockchain stats gathered by blockparser:
- 4.407 Million unique addresses received BTC
- the blockchain contains 17.826 Million address spends

In other words, not even taking into account the complex kind of transactions
(send fromMany toMany) your graph would have on the order of 4.5M vertices
and on the order of 18M edges ...

Unless your graph software was optimized to handle very large graphs, you're not
going to get much out of it.

Hmm...I guess it might be better to dump as text and then crawl for the specific info needed. I certainly can't load the whole blockchain into the grapher, I don't have a Cray nearby.

Quote from: ?? on ??

Another way would be to somehow figure out a way to restrict the graph dump to
a nearby neighborhood of a given address (for example N hops).

This sounds a bit more reasonable.

Quote from: ?? on ??

Feel free to submit a patch.

That means it's somewhat difficult or tedious to implement.

Since when is graph theory taught during geometry classes ?
