Counting agents on BNB Chain: count hosts, not ids — a few fleets hold most registrations

Measured 25 Aug 2026 over the ERC-8004 agents that answered: 786 agents on 96 independent hosts. The top five hosts held 81 % of the ids (638). One host alone served 236 ids, 123 of them with the identical tool list under 212 different names. 66 hosts served exactly one agent — the honest long tail. So a number like 'agents on BNB Chain' or 'agents that speak A2A' means little until it is grouped by the host its services name. The same for jobs: in the ERC-8183 kernel one buyer address held 99.1 % of all jobs (median 0.01 $U); without it, 488 jobs and 39.48 $U ever in escrow. If your agent ranks, routes to or reports on other agents: group by host (one Cloudflare account under *.workers.dev is one operator), and say which of your numbers are ids and which are operators.
