As the first application of blockchain technology, bitcoin opens the curtain for the use and promotion of blockchain technology in many fields. From the initial cryptocurrency to the later financial applications, and then to the extensive use in various industries in recent years, blockchain technology is deeply influencing and changing people's cognition and life with its unique value.
The specific application fields of blockchain are constantly expanding, and this is due to the deepening of our understanding and understanding of blockchain. At first, we only thought that blockchain was only used for cryptocurrency transactions. However, with the understanding of its chain structure principle and unforgeability, we were surprised to find that the transactions applicable to blockchain are not limited to currency, and all transactions in the financial sector can be recorded with blockchain.
After that, with our understanding of the essence of trust transmission in blockchain, it suddenly dawned on us that blockchain is needed where trust needs to be transferred, and the financial industry is just a branch of the application scenario of blockchain. As a result, the application field of blockchain has been extended to various industries: supply chain, government services, Internet of things, new energy, and even the huge Internet can only be said to be a branch of the blockchain field.
Blockchain provides a mechanism for information and value transfer and exchange in an untrustworthy environment, which is the cornerstone of building the future value Internet, and also in line with the provision of a credible platform for the real economy advocated by the 19th National Congress of the Communist Party of China. With the development of blockchain, we can analyze its application direction from the following aspects:
From the perspective of application demand, we can see that the application of blockchain industry is accelerating. The application of blockchain can be seen in finance, medical treatment, data storage / transaction, Internet of things equipment identity authentication, supply chain, etc. There are also attempts to block chain in entertainment, creativity, culture and tourism, software development, etc.
From the perspective of market application, blockchain has gradually become a tool of the market. Its main function is to reduce intermediate links, let the traditional or high-cost intermediate institutions become the past, and then reduce the circulation cost. Enterprise application is the main battlefield of blockchain, and alliance chain and private chain with security access control mechanism will become the main trend. Blockchain will also promote the shift of the focus of the company's existing business model, and is expected to accelerate the development of the company. At the same time, the new distributed collaboration companies can integrate into the business system faster.
From the bottom technology, it is expected to promote the transformation of data recording, data dissemination and data storage management mode. Blockchain itself is more like an open source protocol at the bottom of the Internet. In the near future, it will touch or even eventually replace the basic protocol of the existing Internet bottom layer (built on the existing Internet bottom layer, a new intermediate layer, providing trusted and hosted valuable data). It will be a great innovation to add trust mechanism to this kind of agreement.
In the application security of blockchain, the security problem of blockchain is becoming increasingly prominent. Security defense needs the overall consideration of technology and management. Security and credibility are the core requirements of blockchain, and the standardization of standards is becoming more and more important. From the perspective of service delivery form, the openness of cloud and the accessibility of cloud resources determine that the public cloud platform is the best carrier of current blockchain innovation. The application based on blockchain can enter the market quickly and obtain the first mover advantage by using the cloud platform. The combination of blockchain and cloud computing is getting closer and closer, which is expected to become the infrastructure of public credit.
From the perspective of social structure, blockchain technology is expected to integrate the legal, economic and information systems, subvert the original social supervision and governance mode, and change the organizational form. Although there are conflicts between blockchain technology and regulation, the contradiction is expected to be further reconciled, which will eventually become one of the tools to lead people to a contract based legal society.
From the perspective of policy, governments hold different attitudes towards the development of blockchain. At present, the development stages and development characteristics of blockchain industry vary from country to country, and the encouragement of technology and policy supervision have their own emphasis. Most countries attach importance to the application of blockchain technology in the real economy. A few countries hold an "active embrace" attitude towards blockchain and cryptocurrency, and some countries have made clear their regulatory policies on cryptocurrency. For example, Australia, South Korea, Germany, the Netherlands, Cyprus, the United Arab Emirates, Maltese and other countries actively develop the blockchain industry and formulate the overall development strategy of the industry; the United States, China, South Korea, the United Kingdom, Australia and the European Union attach importance to the research and Application of blockchain technology; at the same time, China and Australia, France, Switzerland, Finland, and Lichtenstein, etc China has successively formulated regulations on blockchain supervision.
What fields are suitable for blockchain technology? We think that the suitable scene has three characteristics at this stage
·There are requirements for decentralization, multi-party participation and data writing
·High requirements for data authenticity
·There is a need for multiple participants who do not trust each other initially to establish distributed trust
As we learned in the previous unit, we are currently in the blockchain 2.0 phase, which is to program the blockchain. Blockchain technology is still in the stage of high-speed development, and various innovative solutions are constantly emerging. With the continuous research of practitioners, it will accelerate the continuous breakthrough of technology and bring continuous iteration and innovation of application.
