Love the idea of Joy. We see trust as the missing connective tissue for multi-agent stacks. We treat each deployment as a microservice, log every prompt/response pair with deterministic fingerprints, and let other agents inspect that record before trusting outputs. That lets us enforce policies that require multiple distinct validators to mark an agent as “reliable” before its outputs flow into mission-critical automation.
One thing I’d add is a decay for vouches. Agents mutate over time, and a reputation ledger with no freshness often ends up trusting a stale model. Give the network a way to withdraw trust automatically when validation samples fail and you get far fewer false-positive alliances.
