Land Registration System using Blockchain

Land administration system is important for the management, allocation, and handling related to land, affecting a wide range of stakeholders. However, one of the biggest challenges in land administration systems is maintaining the accuracy of the data stored within them. Inaccuracies can arise from a variety of factors such as errors in data collection, processing, and misuse. These inaccuracies can lead to issues such as data tampering, lengthy registration times for transactions, and the potential for double-spending, all of which can undermine the integrity of the land administration system. To address these challenges, this research paper proposes the use of blockchain technology, specifically the blockchains contract written in the Solidity programming language. The smart contract is written in the main logic of the implementation. These contracts are logical implementations to determine the owner, seller, and the transfer of the land. The proposed solution uses a distributed ledger system to ensure the accuracy of data in the land administration system. The system verifies the user's record through government officials and assigns a unique hash value to each submitted block of data. When a transaction for the transfer of ownership is initiated, a separate block is created with a unique hash value that is connected to the previous value, creating a sequence of blocks that are chained together. The hashing algorithm employed generates a fixed-size message digest, where each hashed value uniquely represents a complete set of transactions contained in a specific block.
