DAP-01·Identity & Physical Specifications

Serialized Lot Identity & GS1 EPCIS Encoding

Globally unique, tamper-evident serialization combining UUID v4 and GS1 EPCIS 2.0 electronic product codes.

DIMENSION 01

Capabilities & Scope

Globally unique lot identification: Every pallet, ingot bundle, and wire spool receives an immutable serialized identifier
GS1 EPCIS 2.0 standards compliance: Universal compatibility with global customs registries and ERP supply chain databases
Dual-layer barcoding: High-density 2D DataMatrix etched directly onto metal surfaces alongside physical polymer tags
Cryptographic UUID v4 generation bound to depository intake block timestamp and validator signatures

DIMENSION 02

Technical Specs & Parameters

Governing Standard

GS1 EPCIS 2.0 / ISO/IEC 15459 Unique Identification Standard

Attestation Cadence

Generated once at certified refinery or bonded depository intake

Tolerance Limit

Zero collision tolerance across all platform historical records

Target Standard

100% Globally Unique Lot Disambiguation

DIMENSION 03

Security Invariants & Controls

Non-Negotiable System Invariants

Uniqueness Invariant: No two physical assets can ever share or re-use a Passport UID across protocol history
Linear Provenance Invariant: State transitions can only append chronologically to the root lot identifier

Protective Safeguards

Deterministic collision checks executed in PostgreSQL master registry and EVM smart contracts simultaneously.

Automated Circuit Breaker

Immediate intake rejection if barcode scan digest matches any pre-existing registered identifier.

DIMENSION 04

Authority & Integrations

Primary Operating Entity

ReserveChain Registry Controller & Depository Intake Officers

Governance Oversight

GS1 Global Standards Agency & Independent Registry Auditors

Enterprise Partner Ecosystem

GS1 Switzerland, Zebra Technologies Industrial Scanners, Intermec RFID

Tamper-Evident Physical Sealing

Every allocated metal parcel is secured under ISO 17712 High Security mechanical bolts and serialized holographic void films. Any breach attempt triggers an automated registry quarantine.

Immutable Cryptographic Provenance

All inspection artifacts, laboratory assay PDFs, and weighing tickets are content-addressed on decentralized IPFS clusters with Merkle root digests anchored directly into smart contracts.

Open W3C Verifiable Credentials

Digital Asset Passports adhere strictly to W3C Verifiable Credentials standards, enabling global participants, banks, and auditors to verify authentic ownership and purity without platform dependencies.
