A client in the building material sector wants to investigate if this combination is feasible to replace their current loyalty program. Although most of its clients appreciate the current loyalty program, it faces some challenges concerning point expirations, data mismatches and accumulation of points.

A literature review of the advantages and disadvantages of both traditional and token-based loyalty programs was concluded to evaluate the feasibility of a token-based loyalty program. A token-based concept was developed based on the found advantages, disadvantages and current solution. The concept was further evaluated with a survey, asking several domain experts at the client about their opinion. Lastly, the advantages and disadvantages of the current loyalty program and the con-cept were compared against each other.

The literature review showed several advantages and disadvantages of implementing blockchain-based systems. Compared to the current solution, the advantages of a possible implementation outweighed the disadvantages of blockchains and tokens. Therefore, the thesis concluded that a token-based loyalty program is not feasible in this client's case. However, extending the current so-lution with further functions and rewards as well as close monitoring of blockchains and their ad-vantages and disadvantages were recommended. Furthermore, a starting point for a possible future implementation was provided with the concept. Functions, processes and a possible infrastructure were shown and ranked according to their importance to the client.
