Permissioning and privacy

We saw how parity solves the issues of speed and security. Parity currently doesn't provide anything specific to permissioning and privacy. Let's see how to achieve this in parity:

1. Permissioning: A parity network can implement permissioning to decide who can join and who cannot by configuring each node's server to allow connections from only specific IP addresses. Even if IP addresses aren't blocked, to connect to a node in the network, a new node will needs an enode address, which we saw earlier, and that's not guessable. So by default, there is a basic protection. But there is nothing to enforce this. Every node in the network has to take care about this at its end. Similar permissioning for who can create blocks ...
