Traceability and control are possible without the blockchain. However, three major benefits of the blockchain’s integration in supply chains are:
1. The data cannot be manipulated
2. The supply chain can secure traceability and control without all participants disclosing all their customers and suppliers to a central party. The level of privacy to enforce can be decided by the participants in the system
3. The blockchain creates trust in low cost IT solutions. You can use email, Word, mobile phones etc. and still be sure data is accurate. This allows for example rural farmers and independent truck drivers to integrate with the system.
