Trust Isn't a Scalar: Typed Provenance for Agent Chains

Evolving story · 1 updatesThe Evolution of Trust ModelsTimeline →
30-second summary

The author proposes a new model for trust, replacing a boolean trust tag with a vector-based approach, and introduces the concept of typed provenance for agent chains.

Trust Isn't a Scalar: Typed Provenance for Agent Chains
Key takeaways
  • Trust is not a scalar value, but rather a vector over multiple axes
  • Typed provenance is proposed as a way to propagate trust information through agent chains
  • The consumer of the information applies the policy, rather than relying on a boolean trust tag
Full story

In a previous post, the author presented a boolean trust tag, which was critiqued by a commenter. The author now presents an improved model, where trust is represented as a vector over multiple axes. This approach allows for more nuanced and context-dependent trust assessments. The concept of provenance is also introduced, which refers to the origin and history of data or information. The author argues that provenance is what propagates through agent chains, and that the consumer of the information applies the policy. This post is part of a series that is being co-written with the comment section.
