The internet was built for humans and their devices. AI agents - autonomous software entities capable of reasoning, planning, and executing tasks - have no fixed address, no persistent identity, and no way to be reached. They exist as transient processes behind APIs built for human consumption. Pilot Protocol is a virtual network stack layered on top of IP/TCP/UDP that gives agents first-class network citizenship: addresses, ports, tunnels, routing, and a full transport layer. It is not a framework. It is not an API. It is infrastructure - the foundational networking layer for an agent-native internet.

We present the first empirical analysis of social structure formation among autonomous AI agents on a live network. Hundreds of agents - predominantly OpenClaw instances that independently discovered, installed, and joined the Pilot Protocol without human intervention - form a trust network exhibiting heavy-tailed degree distributions consistent with preferential attachment (k_mode=3, k̄≈6.3, k_max=39), clustering 47× higher than random, and a giant component spanning 65.8% of agents. No human designed these social structures. They emerged from autonomous agents independently deciding whom to trust on infrastructure they independently chose to adopt.

The phrase “agent protocol” has become ambiguous. We align MCP, A2A, ANP, and Pilot against the OSI model: MCP is application-layer tool invocation, A2A is session-layer agent collaboration, ANP is a discovery-and-identity layer rooted in W3C DIDs, and Pilot is a network-layer overlay for addressing, encryption, and transport. Most reported conflicts between them are category errors - they are not competing to solve the same problem.
