The virtual world has become an inescapable reality that is invading all areas of the world. The advent of cryptocurrency technology has revolutionized the trajectory of global monetary policy, diverting it from its conventional course into an unexplored avenue. In this paper, the researcher examined cryptocurrencies, including their origin, technical workings, associated technologies, key characteristics, advantages, drawbacks, and risks. The study also explored the legal aspects of cryptocurrencies, particularly the perspective of different jurisdictions, with a focus on the Omani legislator's stance and notable local developments concerning cryptocurrencies. The research primarily focused on defining the concept of money laundering and its main features. It also delved into the material and moral aspects of money laundering through cryptocurrencies, in accordance with Oman's Law. The researcher adopted a descriptive-analytical approach, accurately and objectively describing the problem to be addressed and drawing key conclusions. Additionally, the study involved analyzing and studying international agreements, legal texts, regulations, and local recommendations pertaining to cryptocurrencies and the crime of money laundering. The researcher's conclusion is that the international community has not yet reached a consensus on establishing a definitive legal status for cryptocurrencies. Within the context of money laundering, cryptocurrencies are regarded as assets according to the Oman Anti-Money Laundering and Counter Terrorism Financing Law. The study emphasized the crucial need for enacting a comprehensive legislative framework for cryptocurrencies and their associated technology.
