Recently, Blockchain has become a trending topic in the tech world. After the success of Bitcoin and other cryptocurrencies, it had a lot of promise. "Blockchain" refers to an encryption and data structure used to keep track of asset transfers between users of public and private P2P networks. The most critical aspects are openness, faith, and quickness. There are several academic and corporate groups throughout the world, including IBM and Microsoft, that are working on blockchain technology. Blockchain technology is a potential solution for decentralizing today's centralized system and can be used to tackle authentication management issues. A central database now renders the Ministry of Hajj insecure, lacks transparency and necessitates using a third party to process payments. We suggest a system that includes the Ministry of Hajj, agencies, and pilgrims to tackle this problem by making data decentralized. Using Blockchain, we are attempting to manage the granting of permits for pilgrims from within our borders.
