匿名で公平な言論空間の構成に関する検討

Currently, common publication and communication environments are provided by large private service providers, so-called “platformers”. They are basically operated based on commercial and marketing principles. In the environment, a writer is vulnerable to unfair denial of service attacks by a group people with confronting opinions, since the opportunity for the publication is controlled by the platformer’s regulations. In this paper, the possibilities of a trusted communication environment using blockchain technology is discussed. We assume several distributed managers (DMs) issuing accounts of users, which follow minimal regulation to keep anonymity and fair activities of participants. Firstly, the double issuing of accounts from a single user is prohibited and supervised by a blockchain mechanism. Secondly, activities such as publishing, evaluations, recommendation, citation and so on are operated fairly with an allocated number of points. The amount of points is maintained by the blockchain mechanism as well. We discuss the realizability and feasibility of such a system from the points of view of fairness and anonymity
