Supply Chain Traceability
Prove it. Don't just say it.
The Uyghur Forced Labor Prevention Act (UFLPA) and similar global legislations require importers to prove the origin of their materials. A simple "Certificate of Origin" PDF is no longer sufficient; authorities demand granular, unforgeable supply chain mapping.
Nested Passports
A Cable Assembly Passport is not a single document; it is a hierarchy of nested credentials. The final assembler issues the top-level passport, which cryptographically links to passports issued by the raw material suppliers.
Zero-Knowledge Proofs (ZKPs)
Manufacturers often hesitate to share supply chain data to protect trade secrets. PassportCable supports ZKPs, allowing an assembler to prove mathematically that a material does not originate from a sanctioned region, without revealing the actual identity of the supplier.
