There is no centralized node in the blockchain, and all nodes are equal, and data cannot be modified by mastering a single node; enough nodes need to be controlled to falsify data, which greatly increases the cost of falsifying data.
The inherent openness and transparency of the blockchain makes it possible for anyone to inquire publicly, and the probability of falsified data being discovered is greatly increased.
The data of the blockchain cannot be tampered with, and it also ensures that the product information that has been sold has been permanently recorded, and it is impossible to simply copy the anti-counterfeiting information to confuse it and achieve secondary sales.
