Update: ibittler has claimed this bounty.


I'm not sure yet how difficult (excuse the pun) or time-consuming this would be yet, so if the bounty amount is inappropriate or offensive, please post a counter-offer.

What I'd like is some php code that generates an image with everything you see here:



Preferably the code would use some blockchain.info or other api for the data. If that's not possible, then code that relies on a bitcoind instance would also be acceptable.

I tried messaging Pieter Wuille (owner of bitcoin.sipa.be) but haven't had any response as yet.

Well, thanks. Did you just write that yourself? I wonder if I should pay for something that's just been open-sourced.

Just kidding Smiley

If it works, information will seek freedom...

Edit: Nevermind, I see that your code has nothing to do with bitcoin difficulty at all and is just a general graph script. Something to play with anyway.

What exactly is the significance of the "window estimates", are they supposed to represent the expected difficulty increase vs actual difficulty increase? How exactly should those three estimates arrive at a value?

It appears that the graph you posted uses an analysis of percentage increase over 3, 7, and 14 day periods then extrapolates that data on top of the graph using the same X coordinate. Is this true?

Not to discourage anyone, but more of a heads up: ibittler is making good progress on this so far.

Oh, and metacoin, I think you're pretty much correct on how the estimates graphs work.  I won't know for sure until someone programs me something similar Smiley
