Existing big-tech platforms have controlled the sovereignty of digital services and user data, limiting the opportunities for users to experience platforms. These platforms' control policies were no exception in the content area of the platform. Users can only engage with content by viewing, commenting, emoticons, and sharing. Users were limited to engaging with content in the functions and areas designated by the platform, which meant they could not interact with opinion leaders or content creators equally. Consequently, concepts of Web 3 and MyData have emerged with the idea that the sovereignty of platform users should be restored to the user, not the platform. However, many papers on blockchain and smart contracts that can implement these concepts are mostly engineering or focused on laws such as content copyright. This study examines two purposes as a case study of qualitative research methods for a content platform named A3I®. First, this study identified the feasibility of implementing a blockchain-based content platform with universal value. It refers to the universal value that anyone can access information (data) securely and transparently in a Web 3.0 environment, including the concept of MyData, which empowers users to control their data. Second, this study highlighted that the Article Value Evaluation Mechanism (AVEM), including reward and revenue sharing systems, can enhance digital content activation through automatic payment programs of smart contracts in the platform. Furthermore, the study found that A3I platforms based on blockchain and smart contracts have stronger performance on technical and user-centric factors than other platforms without these technologies. In addition, the A3I platform with innovative technologies and AVEM shows better digital content activation by increasing "feedback frequency" than other platforms that increase "content frequency." Therefore, this study has academic and social significance by reflecting the universal values of Web 3.0 in platform design. It also has industrial significance by presenting a feasible blockchain platform business model.
