A Socio-Economic Approach towards Trustworthy 6G Marketplaces of Softwarized Resources

6G provides the promise of sophisticated services dynamically created through the composition of softwarized resources such as holograms, sensing and related vehicular technology, and advanced remote medicine, to name a few. Therefore, within the 6G ecosystem there will be multitudes of heterogeneous stakeholders, such as providers of specialized services, application developers, as well as communication providers, wanting to interact with each other, e.g., to negotiate the use of such resources. Furthermore, stakeholders will be able to join or leave the 6G ecosystem at will. Given the scale of 6G, it will be necessary for stakeholders to be able to buy/sell such softwarized resources in real-time without pre-existing static trust relationships among them, and a variety of trust relationships will need to be supported. At the same time, to encourage marketplace growth, it will be essential to prevent new entrants from being starved out due to the lack of prior trust history. In this paper, we use game theory as an underlying basis for incentivizing and enforcing socio-economic marketplace policies such as social welfare and social fairness. We then demonstrate using formal verification how game-theoretic strategies can be automatically generated to use as a basis for implementation of such policies, and how cooperation among stakeholders can lead to better outcomes w.r.t. non-cooperative approaches in a model of a marketplace with varying trust relationships.
