It is the particular approach to sharding that makes it less secure, to reduce bandwidth.
I agree that sharding reduces security. I wouldn't propose sharding the blockchain as a scapability solution.[/quote]
That if your home computer had to do 2.25TB/day down to be a full node you might not be able to do it, which is a centralising factor.
You're saying that retaining the possibility for home computers to be full nodes is both necessary and desirable.
I understand that many people have made this
claim over the years, but I am not aware of any attempts to actually prove either of those.
One of the problematic implicit assumptions I can identify in that claim is that if home users can't run nodes, the number of total nodes in the network would decrease.
Why would anyone assume that in a future Bitcoin economy that generated 100k tps of demand would not fewer business users running full nodes then than home users running full nodes today?
