Within the master thesis, we developed a prototype solution for tracking products in the supply chain with the blockchain technology, the GS1 standard, security labels and the analysis of the existing Codikett solution. The application allows all members in the chain to update the distribution path and verify the status of the product on historically innocuous shared information. The purpose of the solution is to prevent irregularities in supply chains: black markets, illegal sales channels, manipulation of product sales, product counterfeiting and communication channel between the manufacturer and the final consumer. We developed the application with the Hyperledger Composer.
Blockchain technology can be used in many business applications of scattered services and applications. Today, many business models depend on processes and intermediate functions of central authorities. With the introduction of technology, they can be removed and the processes transferred to all network participants, introduce equality between them and the credibility of information. All participants must agree with a change in the status that is recorded in the chain of data block whose history can not be changed. In order to avoid conflicts between participants, everyone can check the history of the situation. Many believe that technology is the next technological breakthrough.
The masters thesis is divided into two parts. In the first part, we familiarized ourselves with the basic concepts of technology, supply chain and logistics, and an analysis of the existing solution, in which we had a detailed insight. In the second part, on the basis of analysis and good practice, we implemented the solution and compared it with the existing one. In conclusion, we evaluated the achieved result and presented numerous possibilities for further development.
