Jurisprudential-economic study of the value of money and proposing national cryptocurrency based on Islamic values

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.
