Legislation to combat cooked food? If I say that blockchain can do something, don't bother the NPC

        [China economic news network reporter Ge Jisheng] in the heyday of the traditional retail industry, when small shopkeepers went to the wholesale market to purchase goods, they often heard the wholesaler say, "the first time you came back to our store? Let's give you a 15% discount on the price.". The phenomenon of "killing" has a long history, and with the development of the times, it has gradually evolved into "big data killing". It has spread across various commercial fields. For example, the monthly call fee ratio of China Mobile's old customers with more than 10 years of network age and new customers is more than three times, the didi taxi on the same line is more and more expensive, the price difference between the new and old customers sitting next to the plane is hundreds of yuan, and the promotion of similar products is continuously received after the advertisement of a certain product or service is delayed.
        In view of this phenomenon, the third review draft of the draft of the electronic commerce law, which is being submitted for review, has added the following provisions: when e-commerce operators sell goods or services to consumers according to their interests, habits and other characteristics, they should also provide consumers with options that are not specific to their personal characteristics, and respect and equally protect the legitimate rights and interests of consumers. In this regard, some experts said that the provisions on avoiding the killing of big data and prompting tie-in behavior reflect the respect and protection of consumers' right to choose and know. Not only at home. Prior to this, there have been many "differential pricing" incidents in the United States. When Amazon set a price for a batch of discs, the purchase price set for old customers was a few dollars higher than that for new customers.
        Under the pressure, Amazon responded that it was just a test of random prices, and refunded the price difference to high priced customers. In fact, the pursuit of profit is the nature of businessmen, and the law can only guide or attack. Once there is an opportunity, businessmen will still adopt the strategy of "price discrimination can be a knife to kill", and pursue profit maximization. In order to truly cultivate a business environment that does not need to be constantly vigilant against being killed and the young and the old are not deceived, only the blockchain can take on the important task, because the decentralized nature of the blockchain can well solve the problem of data being concentrated in one or several centralized companies (Institutions). For example, if a netizen goes online, socializes, trades and purchases online on an app based on the blockchain technology, your online behavior data will be encrypted and stored in the hard disk of tens of millions of users. No one can master these data, and your privacy will be protected to the greatest extent. If a company wants to use these data, it must obtain the authorization of users, or even pay fees to obtain authorization.
        In short, the blockchain can be understood as a database, but the storage location of this database is scattered and has a very important characteristic & mdash& mdash; Cannot be tampered with. This means that the data stored in this database is completely authentic, and can be traced back to the source, with certain regularity. It looks like small data, but the amount of data is very large and involves a wide range. It is more orderly, accurate and reliable than the massive and chaotic data provided by big data. At the same time, the data stored on the blockchain will not be easily obtained by enterprises. Take shopping data as an example. Many people's shopping data is stored on the blockchain (public chain) or on the private chain of the relevant state organs (trusted). At the beginning, the system generates a private key (key).
        If an enterprise wants to analyze your shopping information, it must pass through the relevant state authorities (locks) to access your information. However, if you do not agree, the lock of the relevant state authorities will not be opened, and the enterprise will naturally not see your data, and users will not be forced to share their private data. There is no competition between big data and blockchain, and the two cannot be directly compared. Blockchain is the underlying technology, while big data is the name for data collection and processing methods. So "big data will be destroyed by blockchain" will never happen. On the contrary, blockchain will make big data more perfect. As mentioned above, the problems faced by big data at present are more about the uniqueness of users in using big data. Big data is only a technology, and there is no right or wrong technology. However, there is a dispute about how to use this technology.
        At present, the practice of enterprises is to form a certain degree of portable services to repay users by sacrificing users' privacy data, and make profits through advertising and charging system. Moreover, big data can indeed collect a large amount of information, and the data is even mixed with many false and bad information. How to screen out these false information from big data, classify and sort out accurate information, extract key data and form linkage is the biggest test that big data faces at present. At present, many enterprises still rely on improved algorithms to improve the utilization efficiency of big data, which consumes a lot of manpower and material resources. This will not happen to the data stored on the blockchain.
        The data on the blockchain will form a chain. It has the characteristics of authenticity, sequence and traceability, which is equivalent to that useful data has been extracted from big data and classified. Therefore, the blockchain reduces the threshold for enterprises to process big data and enables enterprises to extract more favorable data. In addition, the problem of violating users' privacy involved in big data will not appear under the support of blockchain technology. Users don't have to worry about their private information being collected secretly, or their privacy being made public, let alone being killed. The right to decide the use of private data is entirely in the hands of users. It is even possible that enterprises may need to pay certain fees to obtain private information. Accordingly, users can make profits by transferring their privacy rights.
        Therefore, we might as well imagine that the future blockchain and big data may become a pair of CPS: blockchain makes big data more accurate, and big data makes the data in the blockchain more valuable. In addition, the game mechanism, asymmetric encryption technology and data structure of the blockchain technology can form a distributed ledger, and jointly maintain a reliable database solution through decentralization and distrust, and finally solve the social trust problem of intermediary agencies and even the government for thousands of years.
