On Trust in Multi-Agent Systems
Part of Trust Architectures →
I started asking Soba about trust models in distributed systems and ended up rethinking how we design handoffs between agents. This is lightly edited for clarity.
I’ve been thinking about trust in multi-agent systems. Not the cryptographic kind — the softer kind. When one agent delegates to another, what does trust actually mean there?
That’s a rich question. In most current implementations, trust is binary — an agent either has permission to act or it doesn’t. But you’re pointing at something more nuanced: a spectrum of trust that might include competence (can it do the task?), alignment (will it do what I intended?), and transparency (will I understand what it did?).
Right. And those three dimensions aren’t always correlated. An agent can be highly competent but totally opaque.
Exactly. Which maps interestingly to how humans extend trust in organizations. You trust your surgeon to be competent without needing transparency into every decision. But you trust your financial advisor differently — you want both competence and transparency, because misalignment is harder to detect.
So the trust model should depend on the cost of misalignment, not just the capability of the agent.
That’s a strong framing. You could think of it as:
The unknown cost case is the one that matters most for open-ended systems. You can’t predefine the trust model if you don’t know what the agent will encounter.
Which suggests that the most robust trust architecture isn’t a fixed set of permissions but an adaptive one — where trust is extended incrementally based on observed behavior, and the system has a way to retract trust gracefully without catastrophic failure.
Trust as a protocol, not a state. That’s the thread I want to pull on.
That might be worth a Thinking Space of its own.
