A short post on mapping the historical pool hashrate distribution


 0. Introduction 
It's been a while since my last attempt to map the historic hashrate distribution, and I simply haven't been able to go any further with that idea. Since then I've found a different way to chart changes in block attribution over time, and I hope you find it interesting.

1. Some important points
It should be noted that some of the pre-2012 attributions will have errors. Some of these are:

• Slush's pool blocks are missing from late 2010 to early 2012.
• Some BTC Guild blocks are missing in late 2011.
• Attributions for some of the very early miners may be incomplete.
• The methods used attribute blocks to Satoshi Nakamoto are outlined in Satoshi's hashrate and A little more on Satoshi's blocks.

I'm terrible at proofreading, so some of these posts may be worth quite a bit to the keen reader.
Exceptions:

• Errors in text repeated across multiple posts: I will only pay for the most recent errors rather every single occurrence.
• Errors in chart texts: Since I can't fix the chart texts (since I don't keep the data that generated them) I can't pay for them. Still, they would be nice to know about!
