Relational theory of authority separates proof of possession from proof of relationship
Original title: Beyond Proof of Possession: A Relational Theory of Authority
The paper introduces Proof of Relationship alongside PoP, using causal histories to classify executors and prove authorization is occurrence-sensitive.
Proof-of-Possession establishes artifact control but does not determine relational profile or causal history. The authors separate this from Proof-of-Relationship, the property that one occurrence validly continues another. Authorization models use observation-based verdicts and transition-admissibility relations. They classify executors by equivalence relations forming relational profile spaces with attenuation along valid causal histories.
- Two occurrences of the same executor need not be authorization-equivalent.
- Within a PIC lineage, a deputy's authority cannot be imported outside its origin context.
- Successor-side PoP is a possible evidence mechanism, not necessary for authorization.
From the original article
1 min read at arxiv.orgProof-of-Possession (PoP) establishes that an executor controls an artifact (key, token, credential, or capability), but such control alone determines neither the executor's relational profile nor the causal history of an execution occurrence.
