Designing a secure title deed registration model for land transactions in Kenya based on blockchain

The purpose of this study was to design a secure title deed registration model for land transactions in Kenya based on Blockchain. Blockchain technology creates a publicly accessible distributed database that keeps track of all land transaction records, allowing confirmation of land ownership at any given point in time with the aim of creating a secure and transparent environment that guarantees the much-needed confidentiality and integrity of land transactions. Design Science research methodology was adopted by the research to provide an overall scope in the model design and development requirements, while the Proof of Concept (PoC) research methodology was used to design and develop the essential modules for the model. The research employed subjective sampling to select users to perform a criteria-based model evaluation approach against the evaluation metrics (persistence, time stamping, transparency and decentralisation) set out by the research. Results were presented in the form of a descriptive summary of the users' feedback. From the results, the study established that the model could effectively execute immutable, time-stamped, transparent and decentralised land registration and land transaction processes that can be used as authentic proof of land ownership. The study concluded that the proposed model enhances transparency and security, contributing to a more reliable system that fosters public confidence. The study recommends that future research may focus on the integration of Blockchain with land taxation systems as well as the adoption of cryptocurrency as a legal tender to facilitate the execution of smart contracts for properties in Kenya.
