A researcher made questionnaire are applied, in addition to interview, for data gathering. The under-study research population includes steel industry experts out of them, 12 experts were selected for data gathering phase. Conducting the research, first applying fuzzy Delphi method, 5 main factors and 25 important sub-factors were identified. Then, using fuzzy DEMATEL and interpretive structural modeling (ISM) methods, the importance of each facto was determined, in which two factors "external environment study" and "internal environment study" were at the highest level of the importance, while "Waste reduction", "waste recycling" and "purchasing based on environmental products" were at the last level.

Internet-based financial systems and communications have entered a new phase with the advent of blockchain technology and cryptocurrencies. The new economic system with its transparency, privacy, and peer-to-peer networking, has attracted the attention of economists. The advent of cryptocurrencies has brought new blood into the veins of blockchain technology and accelerated its growth. After a decade of cryptocurrency lifetime, it is necessary to identify key components to develop the use of this technology. The aim of this study is to identify the indicators needed to develop the use of blockchain technology and cryptocurrencies in financial systems. A total of six indicator groups were identified including technology, legislation, cybersecurity, regulatory methods, public acceptance, and investment. For this purpose, the three-round Delphi study is used to elicit expert opinions. Calculation of Kendall’s W coefficient shows a high degree of concordance of experts' opinions in determining the indicators. The indicators presented in this research can be a helpful guide for governments and economic sections to develop the use of blockchain technology in financial systems.
