Hi, Mark. We were asked on the bitcoin-documentation mailing list about a month ago to work on something like this and we're getting close to a pull request for the Bitcoin.org website. There's a preview here: http://dg0.dtrt.org/en/mining#lucky-attack (Remember, it's a preview and still being actively written/edited.) Discussion about that doc belongs on the bitcoin-documentation mailing list. Here's the particular thread: https://groups.google.com/forum/#!topic/bitcoin-documentation/PKwBcroWGGg Thanks, -Dave -- David A. Harding
