Abstract

Transfer of shares from one person to another happens in two ways, namely On-Market trade and Off-Market trade. On-Market trades are anonymous, meaning, both the seller and the buyer do not know each other. In an off- market trade, both parties know each other and to initiate the transfer of shares, the seller fills out a form named Delivery Instruction Slip (DIS) and submits it to their stockbroker. This method is prone to errors and delays, as even a single wrong entry could invalidate the whole transaction. This paper proposes a secure and immutable framework for transferring shares using QR-based authentication and blockchain technology. By employing the methods proposed on this paper, all the transactions are validated and recorded on an immutable ledger, thus making the transfers free from human errors and reducing the time required to transfer shares from the seller to the buyer from three days to a few minutes, this method provides a faster and more secure solution to retail investors.
