The goal is to make Dubai the leading center for Islamic finance, e-commerce, the digital content industry, design and innovation, knowledge, education, and research, as well as the global reference for Islamic economy standards. The  UAE government has adopted blockchain technology to implement government transactions and to achieve the desired results; the country launched the UAE Blockchain Strategy 2021m.
