The Internet’s Trust Problem: BGP Hijacking, RPKI, and the Role of Blackwell-Scale Compute

Part I The Idea, the Attack, and the Result How BGP Trust, Blackwell-Scale Compute, and Partial Security Collide The Internet Is Not One Network To understand BGP hijacking, you have to discard the idea of “the internet” as a single thing. The internet is a federation of Autonomous Systems (AS) independent “islands” operated by ISPs, cloud providers, universities, governments, and large enterprises. Google is an AS. Amazon is an AS. Your ISP is an AS. Each one controls its own infrastructure, policies, and routing decisions. What connects these islands is Border Gateway Protocol (BGP) the protocol responsible for telling each network how to reach every other network on Earth. BGP: The Postal Service of the Internet BGP functions less like a secure control plane and more like a global bulletin board. Every Autonomous System periodically announces to its neighbors: Which IP address ranges it owns Which paths it can use to reach other IP ranges These announcements propagate outward, hop b
