Re: Implementing Decentralized RPKI with Blockchain Technology

In such a scenario I’d argue for less automation to prevent such a rogue RIR from being able to cause such a disruption 
to the Internet. 

To expand on what Tom mentioned, Networks are not yet rejecting announcements with a NotFound validation. Even if such 
an event did occur I’d be willing to bet most network operators are going to be leaning on their interpersonal 
connections rather than automation to reestablish peering with networks. The “proof” of showing they are still allowed 
to announce those resources will happen later. In a true disaster things are going to fall back to the least complex 
solution which is simply people talking to people.
