A lot of people think storage is the main constraint. It’s actually the least important one.
  • bandwidth needed to IBD
  • validation time
  • block propagation time, especially between miners
Are all things we need to keep from growing out of control if we want to have a decentralized and permission-less system.
As more bandwidth becomes more available, and ZKPs start to help with things like the first two, we probably re-do the numbers at some point.
