Abstract

The invention relates to the field of sustainability, in particular to the field of sustainable industrialization. The invention describes trust management within decentral networks including a plurality of decentral network nodes. These nodes, associated with product supply chain participants like producers, users, or digital passport generators, can collaborate for efficient data exchange and verification processes. Producers may request specific rules-based credential generation at issuer nodes, while users receive these credentials from producers or other nodes for verification of received data.
