Pluggable Integrity Layer for Property Registration

Property registration plays a crucial role in property transfers; hence, it is necessary to ensure the transparency and integrity of the property registration records. In this paper, we present our successful deployment of a Hyperledger Fabric [1] based integrity layer for property registration in the state of Karnataka, India. Unlike traditional approaches that build the entire system on the blockchain, we propose an integrity layer approach that leverages the benefits of blockchain while addressing its limitations in terms of speed and complexity. Our solution aims to enhance the existing property registration system by integrating a pluggable layer that can be adopted by any state, considering the diverse state laws governing land (property) in India. We comprehensively address various practical scenarios in property records, including the registration of attorneys and encumbrances on properties. To facilitate user interaction with the blockchain, we have developed a Java card as a hardware wallet, which could be of independent interest.
