“Mossland” is a location-based Augmented Reality(AR) mobile game based on real estate. Users can identify real properties in vicinity, acquire and trade them in the game. Virtual properties in the game can be tradable and liquified through cryptocurrency exchange, so users will put time and effort to increase the value of their properties. Augmented Reality Virtual property value in the game is proportionate to the number of check-ins in the properties and the owners will install “Accessory”, AR objects in attachment to the virtual properties, which is the most effective way to draw attentions from the other users. Accessory will not only make the virtual properties visually attractive but also provide in-game benefits to the users, which would increase the number of visitors. As more people join the game, more properties would be installed with various AR Accessories. It would be visually attractive to see how the familiar cities’ landscape changes their images with exotic AR visuals, which would be a great marketing point for this game. Figure 1: Real property + Accessory (Augmented Reality object) Tradable Properties and Accessories Properties and Accessories of the Mossland can be traded between users through in-game auction system. Such transactions between the users can be done by using “Moss”, which is an in-game currency matched with “Moss Coin”, a cryptocurrency secured by blockchain technology. Moss Coin is expected to be listed on the cryptocurrency exchanges, providing liquidity to the users who have made transactions with Properties and Accessories. 3 Figure 2: In-game Auction House.

Any users of Mossland can create and run advertisement campaign through a simple interface after setting an ad budget using Moss.

AR Accessories will not only add fun experience to the users in the game but also provide tangible value which would be accepted positively and welcomed by the users.
