A Blockchain Based Land Registration and Ownership Management System for Bangladesh

From the times of Satoshi Nakamoto's Bitcoins invention in 2008 Blockchain has become one of the most popular technologies to keep records secure, immutable, transparent and in distributed ledger. Blockchain is the underlining technology of Bitcoin. Blockchain technology has been used in many domains such as IoT, healthcare, education, business, Land management and so on. Among them Land Registration and Ownership Management is a very tough process all over the world. Land is a state immovable object and many frauds claim false ownership. It creates disputes among people. Also, many intermediaries are involved in this system. These intermediaries take huge amount of money to solve problems in time. For this reason, many people fail to achieve their own land. Blockchain technology has the all characteristics to solve these problems. It keeps data transparent, immutable and secure, at the same time it does not need any intermediaries. For the powerful characteristics of blockchain technology, the authors of this paper proposed a permissioned blockchain-Hyperledger based solution model to solve the problems of land registration and ownership management system. Here the authors present a system overview of the proposed system, a flowchart of working flow and an architecture. And last of all, some basic algorithms are also built to conduct a proper research.
