Lasker}, title = {{An Architecture for Trustworthy and Transparent Digital Supply Chains}}, pagetotal = 35, year = 2026, month = jun, abstract = {Traceability in supply chains is a growing security concern. While Verifiable Data Structures (VDSs) have addressed specific issues, such as equivocation over digital certificates, they lack a universal architecture for all supply chains. This document defines such an architecture for single-issuer signed statement transparency. It ensures extensibility and interoperability between different transparency services as well as compliance with various auditing procedures and regulatory requirements.}, }
