Blockchain-Based Secured Estate Property Registration System: Baghdad Estate Registration as a Case Study

Estate property is a very important document to guarantee the rights of the owners. The issue of maintaining these documents is an arduous issue. Because the owner of a property may change frequently, it is challenging to maintain exhaustive and lengthy records of ownership transfers. The problems are exacerbated by falsified or incomplete records that are difficult to track over time. In this research, a system based on blockchain technology is proposed to create and implement a smart contract to facilitate the work of the system. It is implemented on the Binance Smart Chain platform to keep estate property records and to prevent manipulation and fraud. The system uses the keccak256 algorithm to create a unique hash for each bond based on its information. This hash helps to verify the validity and integrity of the transaction and to ensure that there are no two identical bonds. The proposed system is designed for Baghdad estate registration as a case study that uses formal information as practical implementation and as the initial stage for developing the whole system. The system increases reliability and makes the circulation of real estate transactions transparent, efficient, and secure.
