"Blockchain technology," also known as "distributed ledger technology (DLT)," ensures transparency, security, traceability, immutability of information, and decentralization. This technology offers a promising outlook for reducing or solving many managerial challenges, such as fairness, and has positioned itself as a critical factor for the sustainability of companies and organizations through its value proposition of "trust." This study aims to design development strategies for a blockchain-based ecosystem by leveraging established and validated models of this technology to create an efficient, secure, and transparent platform in the service delivery chain of a defense service organization. To achieve this, after identifying the essential requirements and drivers of change, the internal and external factors will be specified as the basis for determining strategies. These strategies will then be aligned with validated national and international models, and the components, tools, and platforms of this ecosystem will be presented. To address the research questions, a mixed-methods approach was employed, utilizing questionnaires and expert opinions from the fields of management within the organization and blockchain technology. Finally, based on the obtained results, a strategy map for establishing this ecosystem is provided.
