Rejecting the arguments of the sanctity of bitcoin mining and proving its legitimacy by Reward Contract (Joaleh)

Bitcoin soon attracted the attention of experts and the general public around the world, including the Islamic community. Due to the novelty of the subject, although little research has been done to examine the legitimacy of bitcoin mining from the perspective of Muslim thinkers, this paper is responsible for examining two reasons in the research of contemporary Sunni thinkers. The two reasons for "violation of the sovereignty in the issuance of money" and "the truth of gambling" are among their strongest arguments for the sanctity of bitcoin mining. A comparative analysis of these two reasons leads us to the conclusion that in addition to the major premise of the sovereign monopoly on the issuance of money, the minor premise of its application to bitcoin mining is not provable; As from the point of view of Imami jurisprudence, there is no valid reason for either the minor or the major premise. As for the title of gambling, although the prohibition of gambling is one of the prerogatives of Shiite and Sunni jurisprudence, but in terms of minority, it is not applicable to bitcoin mining. In addition, the novelty of the present paper is to prove that the title of reward (Joaleh) is thematically and ruling consistent with bitcoin mining, so bitcoin mining can be considered a kind of Joaleh, which is considered a religious and valid unilateral obligation.
