Land Records System Using Hybrid Blockchain

Abstract

Maintaining land records is a difficult task for countries with large area and population. Having a central database server is not a 100% safe alternative to paper-based traditional records as it is susceptible to cyber-attacks and frauds. This paper proposes an idea to solve this issue using blockchain. The proposed land records system is based on a hybrid blockchain network. The existing land records are put on the blockchain by the government. All land sales transactions are recorded on this hybrid blockchain. These transactions are mined (verified) by a miner which is run on government authorized peers or nodes. These records or transactions cannot be tampered with. The citizens can view their owned lands and corresponding transactions but cannot make changes to any data on the blockchain. Being based on hybrid blockchain, this system is benefitted by advantages of both the types of blockchain-public and private and is more secure and reliable than databases and paper records.
