In the modern software industry, which is in constant expansion, the problem of trust between different users of the software solution is becoming increasingly dominant. End users want to be completely sure that the product or service is fully compliant with their requirements and that the quality does not deviate from the selected or ordered product or service. Manufacturers or service providers, on the other hand, want to have complete information about the quality of raw materials or infrastructure they provide in order to create products and services, which should be provided by the appropriate supplier. All participants in the software solution (actors) as an imperative have the security of their own data that is stored, processed and exchanged within such software system. The aim of this paper is to demonstrate the application of an innovative approach in the storage, processing and exchange of information using blockchain technology with a case study on the supply chain. There are different approaches and in the first step the corresponding ones will be compared: Ethereum and Hyperledger Fabric blockchain network / platform. After selecting the appropriate technology, the work will focus on examining the potential security solutions that blockchain technology provides for the needs of the use case. This means that it is first necessary to explain the specific concepts of blockchain technology, then make a use case model, describe it in detail and deepen it to an adequate extent, and finally test some hypotheses related to improving transparency, information integrity, maintaining network security, maintaining effective initiatives for participation and defense against bad motivations of all actors within the system.
