And so is my PC a server by your definition. The website uses javascript to query what my computer’s environment is. So in fact the internet server is now making my PC a server (your definition) because it is now replying to a request from the other computer for information (my environment)
Its the circular argument. Everything is a server so a vault must be a server because it supplies some data. But it is also a client since it sends a request to other vaults which supply info to it. By your definitions then a vault is both a client and a server.
But you know we engineers decided that P2P devices which send requests and respond to requests when part of a P2P system is best not to confuse the issue and realise that a server is NOT a device which responds to a request but much more than that. Thus servers have to do more than just supply a piece of data when requested. And your definition is both wrong and if ever correct is very outdated.
The SAFE network is basically one server made up of a distributed set of components working in a P2P fashion.
