Blockchain technology can be used in IT systems of different fields to eliminate the third party. The number of blockchain applications is growing and the need for the trustworthiness of those applications is critical, as they often process sensitive data. The key features of blockchain technology are its decentralization, immutability, transparency, and security. The main goal of this master\u2019s thesis was to research how trustworthy blockchain applications are developed and which factors establish trustworthiness in the context of blockchain technology. This research was conducted as an integrative literature review and a case study, in which both interview study and grounded theory methods were applied to the case study part. Primary empirical conclusions were concluded from the results of both parts of the study. According to these conclusions specific features of blockchain technology support the formation of trustworthiness in the system, and the implementing blockchain into the IT system will result as an improvement of the trustworthiness in that system. In addition, it was found that more blockchain-specific tools, methods, and resources are needed for the field of developing trustworthy blockchain applications.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2021-05-28T11:54:31Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2021-05-28T11:54:31Z (GMT).
