Qualitative participants Twelve technology experts were purposefully selected for in-depth interviews. Data analysis using open and centralized coding. In the quantitative section, 232 IT specialists were selected by simple random sampling. Their opinions were collected using a questionnaire and analyzed by variance-based structural equations. The results show that the emphasis of experts on the economic opportunities of businesses includes: digital transformation (transparency, reduction of errors and fraud, elimination of intermediaries and non-elimination and manipulation of data), innovation (startups, smart tracking and business flexibility) And competitive advantage (participation in decision making, building trust and decentralization).
