DMarket is a global marketplace solution that turns every virtual item into a real commodity. This paper discusses how we combine blockchain technologies and seven years of industry experience to open this multi-billion dollar market to the existing world economy. All that time people spend playing games on their mobile, PC, console or any other platform could finally be worth something. Essentially, DMarket is a new ecosystem where gamers, developers, and entrepreneurs can efficiently and securely evaluate and trade virtual items. Thus, DMarket creates a new economy that joins with existing real-equity markets. Early-access to the present paper was given to a number of individuals from the gaming industry and blockchain community. The authors deeply thank and acknowledge the comments and criticisms that have made the design of DMarket and this whitepaper as good as they are. Any faults that remain are, of course, the authors¡¯.
