Paper Abstract:	Food waste is a major global concern and engenders profound ramifications of environmental and socio-economic dimensions, while on the other hand, food insecurity affects a significant part of the global population. The co-existence of food waste and food insecurity in urban environments is a paradox of modern cities. The research project presented in this paper introduces a solution using blockchain technology to address both of these issues, simultaneously. The project aims to develop a decentralized mobile application (dApp), which facilitates the reduction of food waste and provides safe and nutritious meals to food-insecure individuals. The tokenization capability provided by the blockchain technology, through the utilization of smart contracts, is used to incentivize food waste reduction and track surplus availability. Citizens use the project's token as currency to purchase food portions, while the participating food service establishments from the retail sector, receive the tokens in exchange for the saved surplus. In this paper the architectural design and all the components of the decentralized application are outlined and described and a holistic view of their interconnection into an IT architecture is provided. This description is followed by an initial discussion of the tokenization process of the proposed ecosystem and its main characteristics that are going to guide the development of the project's tokenomics, by taking into account token's supply, distribution, utility and market demand to estimate the token's value.
