How to Measure Similarity between Source Codes of Cryptocurrencies for Detecting Plagiarism (Lightning Talk)

Abstract

Since Bitcoin appeared in 2009, various other cryptocurrencies have also begun to attract attention and supporters. At the same time, because many cryptocurrency investors want to make a profit using cryptocurrencies, cryptocurrency exchanges list them without any special or technical verification. Cryptocurrency developers often write white papers to describe their cryptocurrency's special techniques and expected future worth. However, based solely on the contents of the white paper and/or a surface inspection of the source code, we cannot know if the developer has simply leveraged existing code bases without incorporating novel functionality. In order to address this problem, we present a framework to measure the similarity between the source codes of cryptocurrencies for detecting plagiarism.
