There are many reasons I enjoy working at coinometrics.com, and having access to data I wouldn’t otherwise have is chief among them. Recently, Jonathan Levin had been discussing whether or not Satoshi’s coins had been moved (which was in the news at the time) and Martin Harrigan of QuantaBytes(who had recently started working with us) was able to provide the sort of data that we needed to assign blocks to Satoshi.
With that information I was able to do what I’d wanted to do since I first started mining – estimate Satoshi’s hashrate. At the time I didn’t realise that I would also be provided with a small window into the great man’s thinking – his plan for managing his personal hashrate.
