Ken, this is great. Cryptograffiti is also great. I have been looking for something to counter the potential Mandela effect if a powerful enough force alters the blockchain. In "Contact," Carl Sagan pointed out that when government is spending the money, they might as well do everything twice because they have no bottom line. So they could run computing power parallel to and hidden from the world to generate their own blockchain and then deploy it with whatever differences they want, assuming they amassed enough computing power. Loads of people would complain that Bitcoin is messed up somehow. A large number of balances would be wrong. No one would know what happened because we all rely on the machines to remember and protect the "longest chain" under the assumption that we won't get 51% attacked.
But this post gives human beings some incontrovertible expectations about the "real" blockchain - an image of Mandela himself! So beautiful.
Thanks!
