Privacy and authority

Privacy effect: Distributed custody can reduce single-key exposure but adds participant metadata and recovery complexity.

Authority boundary: A signing quorum proves configured key control, not legal legitimacy or merits review.

Dependencies

  • participant governance
  • secure share custody
  • nonce discipline
  • rotation and recovery

Risks

  • share compromise
  • availability loss
  • quorum capture
  • implementation errors

Evidence and truth boundary

Open evidence context

Descriptive standards map only. A record does not prove Patefacere adoption, Eviulon legal adoption, interoperability, conformance, passport issuance, credential presentation, live revocation, production trust anchors, or external recognition. External specification status is recorded as source-derived and review-due unless the specification is packaged locally.

Authority and record status

Responsible authority: external cryptographic standard candidate.

Source-derived status remains externally unverified unless packaged locally.

Revision date: . Public corrections may be initiated through the diplomatic contact route.
