The goal is to establish an integrated system through a blockchain platform for various service platforms such as delivery, travel, and shopping used through mobile apps. It is also designed to support the ownership and value of app user-generated data, such as content and reviews. Cashback is widely used on various service platforms to increase brand loyalty. However, cashback typically offers a fairly modest amount of money in relation to customer satisfaction. MILO provides a platform for integrated management of cashback points provided by various service platforms. The MILO platform allows users to exchange cashback points on any platform to consolidate the minimum amount into a more valuable amount. When different service platforms can exchange cashback points, they can attract new users and increase brand loyalty. In addition, existing platforms have limitations in that users cannot trade ownership of their own content, reviews, etc. However, MILO provides an innovative platform concept that allows consumers to transfer and sell the rights and values of content and reviews created by consumers to companies. This allows consumers to protect their creative rights, such as content and reviews, and allows companies to use consumer data for purchasing and marketing purposes, which can have a positive impact on advertising effectiveness, ratings, and reputation management. It can also increase the amount and quality of information provided to consumers. The MILO project addresses these challenges by discovering the value of data and creating an ecosystem where consumers and businesses can interact and collaborate. It aims to create social value that everyone grows together by serving as a platform for innovative use of underutilized data in existing markets, actively participating and creative activities through consumption and purchase of consumer data, and providing solutions using blockchain technology.
