        If we live in an environment without government, companies and banks, how can we conduct reliable and fair cooperation or transactions among people? Such cooperation or transaction may be possible between acquaintances, but it is very difficult to complete such cooperation and transaction between strangers and groups without mutual trust. There is a complete lack of necessary mutual trust between strangers, and both parties do not trust each other. If the trust relationship extends to the whole society, everyone forms an island of information trust, which makes the whole society loose and unconnected, and it is difficult to develop.
        This is also the problem of all Byzantine Generals. Although the army is large, there is no mutual trust between generals, and it is difficult to conquer an island in the end. We need to build trust by building various organizations and groups, so as to carry out cooperation or transactions and promote social development. Then we take the bank as an example. For example, when the bank appears, the economic transaction relationship is different from the original one. As a fully stable and reliable third-party authority, the bank is located on both sides of the transaction. At this time, the bank acts as a trust intermediary between strangers, Both sides of the transaction agree with the unshakable credit of the bank, and interact with the bank in terms of their own capital flow. As an intermediary, the bank communicates the capital flow between strangers, thus completing the reliable transaction between strangers. At this time, the bank becomes the center of the transaction relationship of the whole society, and everyone contacts the bank, and gradually makes reliable transactions with other people. As for the currency issued by the bank, In fact, the representative of the bank's reliability and trust is the certificate of the bank's trust. Under the current rapid development of the Internet, network transactions are frequent and the transaction volume is huge, which has become an important part of the national GDP.
        Therefore, it is particularly important to ensure the reliability of online transactions. The current online transactions need to rely on the third-party trust institutions. The transaction relationship between the network environment and the real environment is very similar. The buyer and the seller lack the necessary reliable trust, so the transactions involving their own interests are not so easy to complete. Then, the credibility of the buyer and the seller depends on the guarantee and maintenance of the third-party institution. The buyer stores the required funds in the third-party trusted institution. The seller provides goods or services to the Buyer under the driving of this event. When both parties confirm that the commitment of both parties has been made, the third-party institution completes the transfer transaction of capital flow.
        These third-party trading institutions, such as wechat, Alipay, online banking, Amazon, meituan and other platforms that we often use, provide various trading services. Then, the current sharing economy relies heavily on the trust of the third party. This highly centralized trading relationship network must have its own advantages, but it must have its own disadvantages. First of all, the security of institutions that are too low and too centralized is relatively weak, but they are prone to collapse when the outside world has a serious impact on the institutions, unable to provide stable and reliable services to the outside world, and the disaster tolerance capacity is poor. Second, the trust center is not always reliable. The trust center is maintained by a group. It is inevitable that internal personnel will secretly attack the organization for their own interests and damage the interests of users. At the same time, the trust center may consider its own overall interests and take extreme measures.
        Third, it will increase transaction costs. Transactions based on the third-party trust center must pay additional trust costs in order to improve the trust degree, thus increasing transaction costs. In order to overcome the disadvantages of the trust center, in 2008, a scholar with the pen name of Satoshi Nakamoto, or also known as a team, published an article called bitcoin: a peer-to-peer electronic cash system, which introduced the development of a fully distributed peer-to-peer electronic money system to the trust center, that is, bitcoin, which we later knew. The blockchain is the underlying technology of bitcoin. Since then, the blockchain and bitcoin have entered the public's field of vision. At this time, we will build this trust system between people point-to-point.
        From the Google search trend, the attention of blockchain technology has continued to rise in the last five years. At present, major Internet companies, stock exchanges, banks and governments have started to make efforts in blockchain technology and seize the new technology. Since the advent of bitcoin, the development of blockchain can be divided into three periods. Its application scope has expanded from the initial digital currency and assets to all aspects of social and economic life, Phase 1.0 is typically represented by digital assets such as bitcoin, phase 2.0 is typically characterized by the application of smart contracts, and phase 3.0 is characterized by a programmable society. At present, it is in the advanced stage of two points zero. The blockchain still mainly focuses on small-scale local applications, and there are few real industrial level and ecological level landing. By the 3.0 stage, the blockchain will become a tool for social governance, with the rule-based trusted and intelligent social governance system as the typical feature, it will realize the social governance mode, from the stage assisted by traditional information technology to the stage of rule of law based on the blockchain order.
        From the perspective of regions concerned, European and American countries and Russia pay great attention to blockchain technology, while China pays less attention to it. The current status of blockchain technology is that foreign countries mainly focus on the research and development of blockchain basic technology platforms and operating systems, while domestic enterprises mainly focus on the application development of blockchain. China's enterprise application development mainly relies on foreign countries, and the achievements of open source communities have not yet produced an autonomous and controllable blockchain infrastructure. According to the report on the testing of trusted blockchain standards issued by China Institute of information and communications in October 2018, half of the test manufacturers use the underlying platform of IBM led super ledger blockchain. Unlike the previous information technology, the blockchain technology characterized by rule governance has strong expansibility. Therefore, the core goal of promoting the healthy development of China's blockchain technology and industry is to first solve the problem of advanced layout, Independent and controllable underlying platform and independent innovation of basic technology.
        We should take blockchain as the core technology, an important breakthrough for independent innovation, clarify the main direction of attack, increase investment, focus on tackling a number of key core technologies, and accelerate the development of blockchain technology and industrial innovation. Blockchain is a trusted system built for the first time in human history. Its core function is to improve the governance ability of all dimensions, which also requires our deep understanding and correct grasp.
