Securing land records using blockchain technology

Abstract

One of the main reasons for land conflicts is due to the actions of the land mafia. In the current day scenario, the land ownership system is under the grip of fraudsters and people often fear being deceived with fake land certificates. In this paper, we consider each buying and selling of land records as a single transaction, wherein each transaction has a unique hash value, which is highly secure in nature. Data being stored on the block are the transactions between buyers and sellers monitored by a closed group of people. Each of this transaction between the buyer and the seller is then validated using the consensus algorithm (proof of elapsed time) and updated as a new block after being marked valid by 'validators' on the Hyperledger Sawtooth framework. This block is then visible to all the members in that network, which incorporates trust and transparency in the transaction system.
