You have to be not just an identity geek, but a dedicated addressing geek, to have even heard of Zooko’s Triangle, let alone understand how elegant an analysis it is of the tradeoffs involved with global identifiers (globally-unique, human-meaningful, decentralized: pick any two). But if you care about this particular neck of the networking woods, Bob Wyman has just redrawn the map. He agrees with those of us who believe the characteristic of identifier persistence is important enough that he’s not only suggested Zooko’s Triangle needs a new dimension, he’s drawn it up beautifully.

So clear was his argument that I updated the Wikipedia page on Zooko’s Triangle to include a reference too his post.

From now on it’s Zooko’s Pyramid!
