Building 3 levels of security for traceability using Blockchain 3.0 Generation

Nowadays, tracking the origin of a product as it goes from raw material to finished product is an essential need of consumers, which determines whether consumers choose to buy that product or not. At present, the most common method of product traceability is to scan the QR code stamp on the goods. These stamps, however, are still being counterfeited, resulting in inaccurate product information, not ensuring product integrity and transparency for consumers. Therefore, this research suggests a variety of blockchain-based solutions with different security levels to improve the security, integrity, and transparency of product data. In this paper, we propose to use blockchain technology 3.0 which has more advanced features than blockchain 1.0 and 2.0, including a transaction processing time of just roughly 6 seconds.
