As their name suggests, trust is of crucial importance in ‘‘trust service". Nevertheless, in many cases, these services suffer from a lack transparency, documentation, traceability, and inclusive multi-lateral decision-making mechanisms. To overcome these challenges, in this paper we propose an integrated framework which incorporates formal argumentation and negotiation within a blockchain environment to make the decision-making processes of fund management transparent and traceable. We introduce three possible architectures and we evaluate and compare them considering different technical, financial, and legal aspects. [less ▲]

Both argumentation and trust concern multi-lateral uncertainties, while argumentation owns the ability to enhance trust in many ways. In the field of trust service where the trustee administers financial assets on behalf of principals, trust is an indispensable element. Often, the trustees withhold the investment plans and of which the decision-making process from their principals such that these services lack of transparency, documentation, traceability, and inclusive decision-making mechanisms. In this paper, we integrate formal argumentation within a blockchain framework. Both argumentation and blockchain have distinctive features that complement each other. They together make the decision-making of the trustees transparent and traceable in order to gain trust and confidence in principals. We introduce three possible architectures and we evaluate and compare them considering different technical, financial, and legal aspects. Specifically, we discuss the role of argumentation in building trust between trustees and their principals. [less ▲]

Abstract agent argumentation frameworks extend Dung’s theory with agents, and in this paper we study four types of semantics for them. First, agent defense semantics replaces Dung’s notion of defense by some kind of agent defense. Second, social agent semantics prefers arguments that belong to more agents. Third, agent reduction semantics considers the perspective of individual agents. Fourth, agent filtering semantics are inspired by a lack of knowledge. We study five existing principles and we introduce twelve new ones. In total, we provide a full analysis of fifty-two agent semantics and the seventeen principles. [less ▲]
