The current study aims to examine the role of cryptocurrencies as an alternative to the US dollar in the oil industry. The oil industry, which has traditionally been dependent on the dollar, has taken a new step with the emergence of cryptocurrencies with features such as transparency, security, and reduced transaction costs. As a form of digital money based on blockchain technology, cryptocurrencies provide new possibilities for managing transactions. By examining the history of these currencies from the emergence of Bitcoin to institutional adoption and the development of national cryptocurrencies, it is clear that this technology can reduce dependence on the dollar and make the oil trade more resilient to sanctions and financial fluctuations. However, there are also challenges such as price fluctuations and the need for appropriate infrastructure. This article presents solutions such as the gradual acceptance of cryptocurrencies by governments, the development of blockchain infrastructure, and the creation of oil stablecoins to replace the dollar.
