I’ve just figured out something, in that step:
The identity code must be generated from https://keybase.io which looks little bit unserious, because it’s not decentralised. What will happen if this website stop working tomorrow?
If this service is the only way to create a full validator node, then I have a proposal - implement some other decentralised system to replace keybase.io… with avatar censorship votings etc. because doing it that way is little bit unserious and unstable.
