Blockchain based Land Registry with Delegated Proof of Stake (DPoS) Consensus in Bangladesh

Abstract

Land Registry documents are legally binding documents provided by the government to owners of land as proof of their ownership. In developing countries such as Bangladesh, it is essential to combat the challenges which a traditional Land Registry system faces. To keep a digital ledger of information about land assets in a transparent an secured manner, Blockchain technology can be used to overcome the hurdle. However, any Blockchain system could fail in the hands of an attacker if the right kind of consensus protocol is not used to secure the chain. The thesis proposes a novel approach on enhancing the Delegated Proof of Stake consensus to provide a private ledger based system secure for transacting land assets which can be easily integrated into the existing traditional Land Registry system for smooth operation. Witnesses are elected genetically while blocks have been customized to cover all the intricate details of the Land Registry Documentation while the system Architecture have been improved to include all sides of the stakeholders. Designated nodes have different roles which enhances the overall model to a structured Hierarchy and also withstand attacks. With the implementation of a Blockchain based system to maintain Land Registry document will allow for data transparency, and immutability therefore making counterfeits and forging almost impossible. This also cuts down the hassle of collecting different documents from different agencies making it easier to obtain land registry documents.

A novel game theory based reliable proof‐of‐stake consensus mechanism for blockchain

“…18 In PoS, nodes referred to as validators initially have to deposit a stake which is in point of fact a number of coins. Likewise, DPoS [19][20][21] was developed to offer higher energy efficiency. However, DPoS is still in its inception stage.…”

Blockchain-Based Land Record System

“…Mahbub Alam Majumdar et al [3] In this paper author has come up with a solution to introduce Council Protocol over delegated proof of Stake. He has also mentioned the structure of a block.…”

On Performance of PBFT Blockchain Consensus Algorithm for IoT-Applications With Constrained Devices

“…This algorithm appeared later than PoW and PoS, so fewer DPoS-based blockchain systems have been developed and researched by now. For example, the paper [31] describes a blockchain-based solution for transparent and secure maintenance of a digital register of land assets; in turn, the authors of [32] present a low-latency secure authentication model for drones in smart cities. They use modified DPoS for drones as a consensus algorithm that does not require re-authentication and can decrease the number of nodes for the authentication process.…”
