Knox receipts — legal posture

Knox receipts have not yet been tested in litigation. The cryptographic primitives — Merkle proofs, hash chains, and Ed25519 / P-256 signatures — are well-established and standardized (RFC 8785 for canonical JSON, RFC 8032 for Ed25519, RFC 6979 for deterministic ECDSA). External Bitcoin anchoring uses the OpenTimestamps protocol (opentimestamps.org). The legal admissibility of any specific receipt format depends on jurisdiction, judge, and case posture. Bonis Systems LLC makes no representation that a Knox receipt will be admitted in any particular proceeding.
