## Description

The search for scalability is reaching its end stages. The rapid advancement of zero-knowledge technology, parallel execution and better virtual machine design solves the "execution" constraint, allowing massive amounts of computation to be compressed to a concise proof. Meanwhile, the data-availability sampling used by Danksharding & Celestia solve the data-availability bottleneck. This leaves us with one final constraint: state growth. Why is state growth so important? And why have other virtual machines not been able to solve this issue?
