This paper conceptualizes the decentralized information systems success model. Based on theoretical and empirical findings in the realm of Information Systems (IS) and Open Source Software (OSS) acceptance and success research as well as various IS enabled socio-economical trends, we define ten constructs (societal norms, economic boundaries, intention to contribute, intention to use, objective quality, heuristic/perceived quality, level of contribution, level of usage, intellectual net benefit and economic net benefit) as well as their relationships. To enhance the understanding of the proposed constructs and relationships, we give examples of the contribution to and the usage of cryptocurrencies. We contribute to the IS research stream of IS acceptance and success by providing a model that allows for an effective examination of decentralized IS success.
