What a Bounded First Layer Might Deliver

The trust layer is best understood as a set of overlapping but distinct functions, each with different technical feasibility profiles and different relationships to the constitutional constraints. The first distinction is between an attestation and a reputation.

The most technically mature function is verified attestation: the ability to record specific claims about a participant's characteristics or history, that they have completed a particular governance process, that they have been attested to by specific other participants, that they have maintained a particular commitment over a specified period, in a way that is verifiable by others without being falsifiable by the subject and without revealing information beyond what the specific attestation claims. Verifiable credential technologies, combined with zero-knowledge proofs, can currently deliver this function for specific, bounded claims with reasonable privacy preservation, subject to a current security and privacy audit. Verification does not prove that the issuer was fair, that the claim remains relevant, or that the context transfers.

The less technically mature function is contextual reputation: the ability to communicate the quality of a participant's relational contribution across contexts in a way that is meaningful to recipients while being resistant to gaming and respectful of the participant's sovereignty over their own record. This function is harder because relational contribution is contextual in ways that attestation is not: what makes someone trustworthy in one relational context may not make them trustworthy in another, and a system that aggregates reputation across contexts risks obscuring the contextual nature of trust in ways that are both epistemically distorting and constitutionally problematic. Aggregation can turn a relationship into a rank.

The minimum viable trust layer, the version that can be built while the more difficult functions continue to be developed, focuses on verified attestation for specific, consensual, bounded claims, with explicit acknowledgment that the more ambitious functions of contextual reputation require further technical and governance development before they can be implemented in ways compatible with the constitutional principles. Attestations should expire. Contextual reputation should remain out of scope until governance, gaming, discrimination, appeal, and revocation have credible answers.
