Nick Szabo already knew in his Bitgold design that consensus can't scale to large transaction throughput securely. So he designed a 2 tier architecture:

1. Bitgold itself, the settlement layer
2. Chaumian digital cash - A peripheral payment network

"Money requires social scalability in its design, via security. For example it should be very hard for any participant or intermediary to forge money (to dilute the supply curve leading to undue or unexpected inflation)."

This is why we're paying so much for all the security.

 The amount of wisdom in Szabos writings is mind blowing. 

Bitgold was conceptualised before bitcoin even existed. 

 Nost Influencers have been influenced by his early work.  

 He seems to have disappeared from the public eye. Would be curious to hear from him again on various things.
