If the network slowly shutdown and only one vault was left standing, it was an enormous archive node, the network would still operate. With this single vault, it would just now be centralised. Or are you saying you would need a minimum of 8 nodes to create one group that contains all the sections?
Its a distributed server, behaving as a single server, made up of many.
If you removed 100% of many, then they weren’t on their own to start with, or am I missing something.
Still think this should be removed. But i’ll stop here.
