🏦 Facebook reported that the effective diameter (covering 90% of all pairs of users) of its social network is five and is decreasing with time.
The equivalent number for the bitcoin transaction network is fourteen and is increasing with time. That is, across 90% of all pairs of transactions, the shortest path between them in the transaction network, ignoring directionality, is at most fourteen hops. The increasing value is likely due to the fact that, unlike the Facebook social network, there is no preferential attachment. New nodes are connected to existing nodes whose corresponding transactions are not yet fully redeemed. In other words, the transaction network is growing at the frontier only.

📈 The notes below are our attempt to re-develop #economic_theory from scratch, namely starting with the axiom that individuals optimize what happens to them over time, not what happens to them on average in a collection of parallel worlds. The latter, surprisingly, is the starting point of the currently dominant form of economic theory.
