Blockchain Based Land Registration System with Hierarchy Maintenance

Abstract

Land registry system denotes to the system that records the particulars of land ownership rights by government bodies. The deposited record can be used as the proof on right and avoid any sort of scam. The aim of this work is to use decentralized system to increase the consistency of land registration and storage of property records based on ownership hierarchy. The system architecture is proposed and implemented here supported with dashboard for land contact owner, land inspector and users. Land inspectors dash board contains various operations like verification of user, land and transfer of property from one user to another user. Similarly, user dashboard contains entry of user details for registration, add land details, land gallery, send request to buy and received request for sale. Here, a consensus algorithm is employed to make nodes in a network like users, land registrar to reach a common agreement about the present state of the distributed ledger. Proof of Stake (PoS) consensus algorithm is utilized to authorize the blocks. The validators will confirm blocks by keeping a bet on them if they notice a block that can be added to the chain. SHA256 is a cryptographic hashing algorithm used which converts an input of arbitrary length into a fixed-size output and is utilized to generate addresses of blocks created when transaction happens. The system is working well as intended with respect to various operations.
