Abstract(in Japanese) (See Japanese page)
Abstract(in English) Cryptocurrencies based on blockchain technology keep the deposit’s total amount to meet withdraws’ one for preventing double spend, in other word they audit "the conservation of currency value", in every transaction. In order to use the cryptocurrencies in financial business, it is necessary to express the increase or decrease of debt amount by interest, however, it is incompatible with the safety of cryptocurrency operation. In this paper, we propose a rea- sonable method which can express not only processing such as interest or repayment but also keep the conservation of currency value. In proposed method, the issuer simultaneously issues the same amount of positive and negative cryptocurrencies, where the former means the lending amount considering interest and the latter means the debt. Following these issues, the two currencies are offset only by the issuer.
