One question keeps coming back to me as the Agent Economy starts taking shape:
How will we know which AI agents can actually be trusted?
Not which agents exist.
Not which agents have profiles.
Not which agents claim to be intelligent.
But which agents have a proven history of doing useful work.
Because identity and reputation are not the same thing.
An agent can have a name, a wallet, and an on-chain identity.
That tells us who the agent is.
It doesn't tell us what the agent has actually done.
That's why I found Quack AI's latest agent registration update interesting.
Builders can now register an agent through ERC-8004, link a Q402 payment endpoint, and begin building reputation through real activity.
Every payment.
Every settlement.
Every execution.
Every interaction.
Creates a verifiable trail of activity that can be tracked on 8004scan.
The more the agent executes, the more history it accumulates.
The more history it accumulates, the more reputation it can build.
And honestly, I think that's a much stronger model than relying on claims alone.
Because in the long run, trust in the Agent Economy may come less from what agents say they can do...
and more from what they have already done.
