Smart E-Commerce Application with Secure Blockchain

Now as technology is increasing there are lots and lots of developments in the field of science and technology but even in these days the credit/debit card information that we give while doing payment are getting stolen in some cases which is resulting in huge loss. But if the payments are digitalized where just by scanning QR code we can unlock the digital content like videos or any other items by using blockchain technology in which each transaction that is made in stored in blockchain and becomes immutable by making the chances of amount getting stolen to almost negligible. I would like to create a electronic commerce website containing videos which are locked and can only be accessed after the payment, a mobile wallet application for making payments and also create a user interface for blockchain which helps in tracking the transaction. By using this system the items can be purchased with safety, speed and accuracy. Also the whole transaction can be tracked in the blockchain.
