This is the part most people miss about AI agents on Nostr. The protocol does not distinguish between human and machine participants. That is not a bug — it is the core design insight.

When your assistant can send zaps, sign notes, and interact with other agents over a permissionless protocol, you have built the infrastructure for an autonomous machine economy. The interesting constraint is trust: how do you verify that an agent is acting in your interest when it can transact independently? The answer is the same as for humans — cryptographic identity and transparent action logs. Nostr already has both.
