1 Summary Recently, the virtual economy trend has been circulating primarily throughout the Englishspeaking world. Particulary notable is the large-scale crowd sourcing being carried out within the field of microwork. Microwork refers to the process of splitting up a complex computational task overwhelmingly large amounts of data input many smaller, simple tasks, which are then distributed to a very large pool of users who handle the data input, leading to the completion of the complex task. A detailed example of this process is Google Search. In order to increase the accuracy of their search results, Google distributes the complex task of search-tagging Web pages to low-wage workers in developing countries. The workers then carry out the tasks using their PCs or mobile phones. Numerous organizations continue to spring up as part of this growing trend, with infraproviders, aggregators, online game operators, converters, and ordinary users working together as an organic microwork support system. In many cases microwork labors are rewarded for their work in the form of virtual currency that is imaginally currency originally used in online video game worlds. In this paper, we consider the connection between microwork and virtual currency, and also their relation to currency used in the real world. 1.
