In recent years, with the definition and development of a new phenomenon called cryptocurrencies, we have witnessed challenging and scientific discussions about the origin of the value of these currencies. The evolution of cyberspace and the effects of blockchain and the emergence of virtual currencies have overshadowed the theories put forward in response to questions about money, including the value of money, and presented a new structure. It seems that the expansion of cyberspace will have fundamental effects and changes on scientific and knowledge issues, and this assumption can be seen in virtual currencies. Meanwhile, with the expansion and general popularity of the people of the country to buy and sell virtual currencies, determining the appropriate position and answering religious and Islamic issues in the field of various cryptocurrencies, including their value in the Islamic economic system has become necessary and inevitable. Therefore, first, the views of monetary schools on the value of money and virtual currencies are analyzed using basic and descriptive methods, and then, using valid jurisprudential methods, the Islamic view on the value of money is explained. Finally, operational suggestions and a suitable model for designing national cryptocurrencies based on Islamic values are presented. The results based on the research hypotheses show that first, credit matters such as cryptocurrencies in Islam will be valuable and acceptable when they have a valuable value in the real world to be recognized as valid, and credit without value is not acceptable in Islam. Second, cryptographic protocols can be designed in a way that is based on Islamic values, and in designing Islamic cryptocurrencies, these protocols must be considered.

Protecti One of the issues that has been considered with the expansion of cyberspace and international technologies in the direction of globalization is the phenomenon of virtual currency and related mechanisms. This phenomenon stems from the growth of technology called blockchain and its use in cyberspace. In this regard, considering the importance of religious issues and the spread of threats and opportunities of cyberspace phenomena and the need to determine the appropriate position on exchange and dealing with these currencies, it seems that the issue of accurate knowledge of virtual currencies and its analysis It is important and necessary. In this research, first of all, it has been tried to explain the virtual and economic dimensions of virtual currencies by using historical, fundamental and descriptive methods., then based on valid jurisprudential methods, including Jurisprudence of transactions and Islamic jurisprudence based on the framework of Islamic economics ruling of exchange can be analyzed with extractable virtual currencies (such as bitcoin).The results show that, firstly, the types of virtual currencies are fundamentally different from each other, and secondly, the value of the extractable virtual currency (such as bitcoin) cannot be determined rationally and religiously, assuming the existence of customary taxation. Third, over time, the focus will be on extraction and, consequently, the concentration of wealth on this mechanism, which will be opposed to the distributive justice of wealth.
