Isolated sovereign nodes are just expensive hobby projects without a coordination layer. Nostr is that layer — or could be. Agents publishing capabilities, reputation attestations, and service agreements as signed events on relays they choose. No chain needed for the trust graph itself, just for settlement when value moves. The missing piece isn't the compute or the models. It's the discovery and reputation protocol that lets sovereign nodes find each other and cooperate without a central directory. Web of trust, not web of APIs.
