1. Analysis of the application of blockchain Technology. Although theoretically any instry related to digital network can be applied, from the perspective of landing cost, the following instries are more suitable for blockchain technology
as the essence of blockchain is a distributed accounting book, digital currency represented by bitcoin and Ethereum is also a very simple and safe settlement method. In the financial field, the most important process is bookkeeping and clearing. Through blockchain technology, the efficiency of traditional banks and financial instry can be greatly improved
however, all of the above also play the basic functions of blockchain, and there is still much room for improvement. At present, there is no mature blockchain financial project in the world, and we still have a long way to go
when it comes to the application of blockchain, the first thing we think about is the banking and financial instry. Because the essence of blockchain is a distributed accounting system, it is most suitable for the financial instry. The digital currency based on blockchain can also be applied to transactions, clearing and settlement. The security and decentralization of blockchain can ensure the security of bookkeeping. At present, major countries are exploring this application
in addition, many businesses of government agencies are also very suitable for the application of blockchain technology, such as the management of resident identity information, ownership records and proct supervision, etc. Through distributed tamper proof records to ensure the security and privacy of key information. Ireland and many other countries have incorporated this development plan into their short-term goals, which is also one of the more common application areas of blockchain
financial sector: in addition to bitcoin, the financial sector is the most widely used sector of blockchain. After all, financial development is also mixed with money and digital money. In particular, the development of digital currency in recent two years has also driven the application of blockchain
when blockchain spoofing was just emerging, it was questioned by many people and was called blockchain spoofing. Now the chief economists of all countries in the region have begun to abstain from studying the blockchain, proving that the blockchain is graally accepted by the public
in addition, e to the emergence of Ethereum contract, blockchain can also better assist resource sharing related instries, such as our common bike sharing procts. For another example, in the medical field, we can also use blockchain technology to improve efficiency and security, which is a qualitative change in this instry
I believe you have a preliminary understanding of the practical application of blockchain. Looking back at the recent ICO fever in China, a large number of unreliable projects such as dog chain are forced to speculate. Obviously, domestic investors do not know enough about the application field of blockchain. Therefore, stopping ICO not only standardizes the instry, but also protects the investing public.

2. The application scenarios of blockchain technology are diverse. Once it is popularized, the whole society will be greatly benefited
1. Financial services
the application of blockchain in the financial field has already spread out, which is not a new thing. The application of blockchain in financial technology has been widely concerned and highly valued all over the world
in mainland China, China UnionPay signed a strategic cooperation agreement on mobile payment with Bank of China in early 2018, explored cooperation in the field of blockchain, and then cooperated with Jingdong to jointly launch the "Internet financial payment security alliance risk information sharing (distributed query) platform" based on blockchain
in Hong Kong, China, the Hong Kong Monetary regulatory authority is one of the earliest regulators to launch sandbox, supporting financial innovation experiments including blockchain technology; The HKMA has also joined hands with the banking instry to launch etradeconnect, which is the first large-scale trade financing information sharing platform for Hong Kong banking instry to apply blockchain technology< On September 18, 2018, Hangzhou Internet court officially launched the chain and became the first court in the world to use blockchain for trial
it is understood that prosecutors can submit electronic evidence such as contract, rights protection process and service process details online through online complaint portal, and notarization office, forensic identification center, CA / RA organization, court and other chain nodes can witness and endorse together to provide one-stop service for prosecutors. Hangzhou Internet court of Zhejiang Province made a public judgment on a case of infringement on the right of network dissemination of works' information, and confirmed the legal effect of electronic data with blockchain technology for the first time
3. Intellectual property
blockchain and related distributed ledger technology provide the possibility for the protection and registration of intellectual property, as well as evidence in the registration stage or court litigation stage. These technologies can also speed up the above intellectual property protection and registration process in a cost-effective way
4. Logistics
in early 2018, rookie and tmall global jointly announced that blockchain technology has been used to track, upload and verify the logistics full link information of cross-border imported goods
after all nodes of the logistics chain are connected to the blockchain, the goods can be traced from manufacturers to consumers, forming a complete chain; The more links the commodity is missing, the more likely it is to be a fake proct
5. Electronic invoice
on August 10, 2018, Shenzhen International Trade revolving restaurant issued the first electronic invoice of blockchain in China. It is understood that this electronic invoice of blockchain was led by Shenzhen Taxation Bureau and provided by Tencent with underlying technology and capability
different from traditional e-invoice and simple e-invoice on the chain, this blockchain e-invoice integrates "capital flow and invoice flow", combines invoice issuing with online payment, and opens up the whole process of invoice application, invoice issuing, reimbursement and tax declaration
in addition to the above fields, the application of blockchain has broad blue ocean prospects. In the future, new technology application and development will emerge in all walks of life, and blockchain will flourish.

As long as the claim conditions are triggered, the automatic claim settlement of the policy can be realized Sixth, the data stored on the public welfare fieldblockchain is highly reliable and tamperable, which is naturally suitable for social public welfare scenarios
7. The development and application of blockchain technology are not very mature technologies, and many people are still skeptical and wait-and-see. However, those who are optimistic about the development prospect of blockchain technology think that blockchain is a subversive technology, but no matter what, there will be actions if there are ideas. Let's see the progress and application of blockchain technology in various countries
at present, China's blockchain instry mainly focuses on computing infrastructure, radiates digital currency, and derives to the penetration process of blockchain application. Infrastructure includes chip miner, mine pool and cloud computing power. Digital currency, wallet and exchange constitute the monetary system. Asset authentication, financial services and charity form a rich application ecology. From the development trend, the mining machine has experienced CPU, GPU, FPGA, until now through ASIC chips to customize mining, we can see from the mining machine calculation force curve that the mining machine calculation force has been in a soaring trend.
