How Useful Is a Distributed Ledger for Tracking and Tracing in Supply Chains? A Systems Thinking Approach

Christian Straubert, Eric Sucky
2021 Logistics  
This practical perspective is complemented by a theoretical systems thinking perspective.  ...  Furthermore, it became evident that DLT can only be useful for supply chain tracing.  ...  If a reputable certificate authority creates correct keys, the connection between a company and a public key cannot be changed easily without it being noticed.  ...
