1. blockchain technology uses mathematical methods to achieve distributed accounting and solve the trust problem, so as to complete the decentralization, which will bring far-reaching influence in many fields such as communication, finance, Internet of things, government management and so on
blockchain refers to the technical solution of collective maintenance of a reliable database through centralization and distrust in the past, and it is a technical way for the whole people to participate in bookkeeping. Previous bookkeeping methods were all centralized and needed centralized intermediary, whether it was traditional government, financial institutions, notarization institutions or emerging e-commerce platform and online payment platform
in economic hypothesis, information is sufficient. In fact, it is precisely because of insufficient information that there are very large intermediaries. The existence of intermediaries increases the transaction cost and raises the transaction threshold. In essence, blockchain technology is a large-scale collaboration tool. It makes direct value transfer possible by using pure technology for the first time, and continues the trend of Internet decentralization and disintermediation. Disintermediated blockchain technology will greatly subvert the information intermediary instry
blockchain technology is the basic technology for building bitcoin data structure and encrypted transmission of transaction information, which realizes the issue and transaction of bitcoin. The core of blockchain technology is that all the current participating nodes jointly maintain the transaction and database, so that the transaction is based on the principle of cryptography rather than trust, so that any agreed parties can directly carry out payment transactions without the participation of a third party
technically, a block is a data structure for recording transactions, reflecting the capital flow of a transaction. In the system, the transaction blocks are connected to form a main chain, and all the nodes participating in the calculation record the main chain or part of the main chain
a block contains the following three parts: transaction information, hash formed by the previous block and random number. Transaction information is the task data carried by the block, including the private keys of both parties, the number of transactions, the digital signature of electronic currency, etc; The hash hash formed by the previous block is used to connect the blocks and realize the sequence of past transactions; Random number is the core of the transaction. All nodes compete to calculate the answer of the random number. The node that gets the answer the fastest generates a new block and broadcasts it to all nodes for updating, so as to complete a transaction.

Blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. Blockchain is an important concept of bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains a batch of information about bitcoin network transactions, Used to verify the validity of its information (anti-counterfeiting) and generate the next block
if such technology wants to be put into application, the biggest problem is the "Impossible Triangle problem"
that is, scalability, decentralization and security cannot be achieved at the same time, and only two of them can be achieved
most of the existing public chain projects in the market are difficult to put into use on a large scale
3. What are the e-commerce sources of blockchain traceability< According to the introction, the food supply chain involves many links such as proction, transportation, storage and sales, so the control of food quality is extremely complex. As a technology with decentralization as the core, the block chain is open and transparent among all parties, So as to effectively form a chain of information and value sharing. Because the blockchain has the feature that the data can not be tampered with, once the data is uploaded, it can not be changed. Therefore, it is easier to make the source traceable and the destination traceable, and truly realize the responsibility traceability< Specifically, the identification number attached to each batch of goods is unique, recording a series of information from planting, processing to store sales. By scanning the QR code on the proct label, consumers can fully grasp the real information of each stage from the source of the supply chain to the terminal. This approach can not only enhance consumers' impression on the quality of Carrefour procts, but also enhance their trust in Carrefour brand; To some extent, it can effectively urge the upstream of the supply chain to improve the quality and safety level
so far, the food safety issues that consumers are most concerned about will also be strongly guaranteed. Carrefour believes that the use of blockchain can effectively help consumers regain confidence and rebuild their trust in the food instry
in fact, it has become a trend to apply blockchain technology to commodity traceability scenarios. Previously, tmall also applied blockchain technology to commodity traceability scenarios in this year's "double 11". It is reported that in tmall International Mall ring the "double 11" period, the commodities traced by blockchain will cover more than 100 countries and regions, and the number of commodities will reach 150 million. The commodities involved mainly include diamonds, imported milk powder, imported health care procts and other cross-border commodities. In addition, Wuchang rice, Maotai (600519, Guba) and other high-end liquors and Pingwu honey will also use blockchain traceability
Third, the combination of online and offline
Suning e-buy launched the blockchain commodity traceability system ring "618" this year. It is understood that ring the "618" period, Suning e-buy's self-developed block chain commodity traceability system was fully opened in Suning e-buy's online and offline stores, with two lines to ensure the quality of goods and reject fakes. Suning applies commodity anti-counterfeiting traceability blockchain technology to track and record the proction, processing, transportation, circulation, retail and other links of commodities, which is realized through the wide participation of all parties in the upstream and downstream instries. Suning easy to buy users in the purchase of goods, as long as the scan proct traceability source code, you can "one click" query proct information< (4) it is suitable for regulatory or instrial closed-loop scenarios.
Wang Maolu, chairman of consensus digital, once told Securities Daily that "blockchain technology is suitable for anti-counterfeiting traceability of commodities, especially for regulatory or instrial closed-loop scenarios. The combination of the two characteristics of blockchain data non tampering and transaction traceability can eradicate the problem of fake and shoddy procts in the process of proct circulation in the supply chain, solve the trust problem existing in the traditional traceability, and protect the rights and interests of consumers. "

The five functions of money are as follows:
1, the function of value scale
specific performance: to price and price all kinds of goods in life to measure the value of goods, and the money to measure the value of goods itself is also a commodity with value
2. The function of circulation means: in the process of commodity exchange, commodity sellers convert commodities into money, and then use money to buy commodities. Here, money plays the role of medium of exchange and performs the function of means of circulation. Popular will be the act of buying and selling, hand in money, hand delivery
3. Storage function
specific performance: money withdraws from the circulation field and acts as an independent form of value and the general representative of social wealth, such as the first, second and third generation of RMB, or other commemorative coins
4, the function of means of payment
specific performance: as an independent form of value, currency performs the functions of unilateral movement (such as debt repayment, tax payment, wage and rent payment, etc.), such as interest payment, wage payment, rent payment, tax payment, etc
The function of world currency is embodied in the following aspects: currency performs the function of general equivalent in the world market. Due to the occurrence and development of international trade, the currency circulation goes beyond the scope of a country and plays a role in the world market, so the currency has the function of world currency. For example, the US dollar is the world currency6.
The reason why Sweden has also joined the ranks of banning Huawei and ZTE equipment is that the role of the United States can not be ignored. At the same time, Sweden also wants to play a certain role in protecting domestic related instries in this way{ RRRRR}
and if we insist on this view all the time and fail to embrace new technology in time, sooner or later, it will be abandoned by technology and overtaken by other countries. In the end, it is the people of the country who will be harmed. Although we can't see the impact of some national policies on our daily life, the Swedish government will regret the technological dividend in a few years
