The three characteristics of blockchain are well known, that is, decentralization, openness and transparency, and non-tampering. Among them, the non-tamperable feature makes blockchain applied to many places. Such as commodity traceability anti-counterfeiting, privacy protection and so on.
With the increasing popularity of blockchain, many small and medium-sized enterprises have begun to lay out and study blockchain, and combine themselves with blockchain technology to optimize and enhance their applications. So among them, how does Alipay use blockchain to achieve product traceability?
In fact, in a popular science program earlier this year, the blockchain director of Alipay introduced the blockchain traceability technology in detail. The popular meaning he expressed is: when you just know a person whose name, age and birthplace he told you, you will have no idea whether the information is true or not, and at this time you just need to look at his ID card.
The same is true when buying a product. When you want to know whether the product is genuine or not, you only need to scan its "ID card" (traceability QR code) in the blockchain traceability machine, then you can know the production details of the product and know whether it is genuine or not.
the traceability technology of blockchain enables buyers to protect their own rights and interests, clearly understand the production process and context of products, and on the other hand, it also optimizes the user experience, so that users can use products with more confidence.
Nowadays, many technologies of blockchain have been widely used, such as charity, rental management, payment by subway and high-speed rail, etc. It can be said that the blockchain has improved social efficiency and brought great convenience to life.
However, although the combination of blockchain and Alipay has brought many benefits, the traceability technology of blockchain is still not perfect.
Because all the production processes traced back to it are uploaded artificially, even the data that can't be tampered with can't be guaranteed, which still fails to solve the substantive problems.
Generally speaking, although blockchain has brought great benefits, it is not perfect after all. However, the technology of blockchain has promoted the development of the times, and I believe its future is still worth looking forward to.
