Secure and Traceable QR Code Using Blockchain-enabled Certificates

The blockchain has been considered to be a breakthrough technology solution for problems based on security aspects. It is a Distributed Ledger Technology (DLT) which can be used to established trust among different trustless entities or nodes present in the network. Furthermore, Quick Response (QR) Codes are likewise one of the most promising innovations going on in the markets. In QR code, small dots are present which get converted to binary numbers and get validated with error correcting algorithms. Hence, QR codes are beneficial for both storage and authentication. In this article, we discuss the prospects of combination of these two technologies for better results. In this paper, we aim to develop permission-less Blockchain, which is relatively easier to compute and have shown to increase its data capacity. It also endeavored to add the QR Code incorporation to a block and make it more scalable with considering the limited space in a such block.
