About

• In today’s world, how do you know if you are buying a genuine product?
• We leverage the idea of Bitcoin’s blockchain that anyone can check the proof of possession of balance. Along with this, we plan to use QR codes.
• We plan to implement a proof-of-concept system employing a blockchain-based decentralized application which gives a customer the entire history of a product ownership (eg - brand info, owner, etc).

Data Flow

Why blockchain?

• Unlike a normal database, Blockchain has a non-destructive (immutable) way to track data changes over time. This means that data is not editable rather, whenever updates are made, a new block is added to the “block-chain”. This helps track historical data (authenticity and owner data) of a product.
• Given the amount of data to be dealt with (large amount of products being developed), if you have to keep track of all of them, it is better to have a decentralized and distributed network of nodes so that no entity can tamper with the product data and we also obtain 100% up time.
• Transparent nature of the Blockchain.
• Using Blockchain, authenticity can be checked and ownership of a product can be transferred easily.
