The model I present in that presentation I now call the tapestry model and I conjecture 1) we need to employ it if we’re ever going to build a decentralized web (ie a functioning WoT) and 2) the brain already implements the model.

And the brain of any social organism has got to have an internal representation of the external WoT — one could consider that to be part of the definition of “social.” If a cortical column (or some other patch of neurons) represents an individual in one’s WoT, and contextual trust ratings are calculated for that individual, then would that qualify as neurons having reputation? Perhaps so!
