1. blockchain instry has great growth potential. Five aspects promote the healthy development of technology. Blockchain basic situation analysis blockchain technology, as a technical solution for collective maintenance of a reliable database in a decentralized way, has the characteristics of decentralization, tamper proof, highly scalable, etc., and is becoming a new technology following big data, cloud computing, artificial intelligence Virtual reality and other technologies are another emerging technology that will have a significant impact on the future, which is expected to promote human beings from the era of information internet to the era of value Internet. Some countries and regions in the United States, Japan and the European Union have promoted the development of blockchain as an important national development strategy, and vigorously promoted the research and development and application of blockchain technology. China also attaches great importance to the technological innovation and instrial development of blockchain. With the joint participation of it and other enterprises, a large number of new enterprises, new procts, new models and new applications have emerged. The application of blockchain in the fields of finance, government affairs, energy, medical and other instries has graally expanded, and is becoming an important force to drive the technological proct innovation and instrial transformation of various instries. The development of blockchain can be divided into three stages, namely, blockchain 1.0, represented by bitcoin and related financial infrastructure applications, and blockchain 2.0, represented by smart contract. At present, it is graally moving towards blockchain 3.0, which is based on blockchain technology and more complex in-depth application of smart contract. Statistical analysis of blockchain investment and financing in the first half of the year since 2016, the frequency and amount of investment and financing in China's blockchain field have increased sharply. According to the statistical data of "in depth analysis report on business model innovation and investment opportunities of blockchain instry" released by foresight Instry Research Institute, in the first half of 2018, the amount of financing in the blockchain field was about 10.7 billion, with a year-on-year growth rate of 1426% compared with the same period in 2017; The number of investment and financing events in the field of blockchain has reached 205, and it is expected that the investment in the field of blockchain will usher in another peak this year. Judging from the distribution of investment and financing rounds in China's blockchain field, the investment rounds in the start-up period (before round b) account for more than 95%. There are many instry pioneers participating in the investment together, and most enterprises are still in the race. Statistics and growth of blockchain investment and financing in the first half of 2014-2018 data source: prospective instry research institute collated the statistical analysis of Chinese blockchain enterprises and registered capital. In 2013 and before, there were only 26 blockchain related enterprises registered in China. In 2016, 116 blockchain enterprises were registered, 158 were registered in 2017, and 52 were registered from January to the end of June 2018. In terms of registered capital, there are 26 enterprises in China whose registered capital is less than 1 million yuan, accounting for about 6%; 197 companies have registered capital between 1 million yuan and 9.99 million yuan, accounting for about 46%; There are 171 companies with registered capital between 10 million yuan and 100 million yuan, accounting for about 40%; There are 31 companies with more than 100 million yuan, accounting for about 7%. Statistics on the enterprises and registered capital of China's blockchain enterprises from January to June 2013-2018 data source: prospective instry research institute collates the statistics of China's blockchain enterprises in terms of regions and fields. Among the 425 blockchain enterprises, 385 enterprises are gathered in Beijing, Shanghai, Guangdong, Zhejiang, Sichuan and Jiangsu, accounting for 90% of the total. Among them, Beijing has the largest number of enterprises, accounting for about 37% of the country. In terms of instry, China's blockchain enterprises are mainly distributed in the fields of finance, bottom public chain, enterprise services, technical solutions, data services, health care, Internet of things, transportation, games, etc. Among them, 91 enterprises are engaged in the financial field, accounting for more than 21%. China's blockchain enterprise field distribution statistics data source: prospective instry research institute collates that China attaches great importance to the development and application of blockchain technology. Driven by multiple forces such as policy, technology and market, the pace of blockchain innovation has been accelerating. It has been deeply integrated with cloud computing, big data, Internet of things and other technologies. The scope of exploration and application has also expanded from digital assets to supply chain management, intelligent manufacturing, instrial Internet, social welfare, right protection and other fields. Five aspects to promote the healthy development of blockchain technology, and promote the high-quality development of digital economy. 1. Pay close attention to the international development frontier, jointly promote the research of blockchain related technology and instry, promote the standardization of blockchain development instry behavior, and create a good development environment. 2. Strengthen the construction of blockchain core technology capabilities. Establish and improve the collaborative promotion mechanism among backbone enterprises, universities and research institutions, guide it enterprises to strengthen technical reserves, accelerate the breakthrough of key core technologies, and improve the performance, efficiency and security of blockchain. 3. Support the development of entrepreneurship and innovation in the field of blockchain, encourage the cross-border integration of blockchain enterprises and user units, guide instry organizations to establish public service platforms, support third-party organizations to carry out blockchain service evaluation and testing, promote the enrichment of instrial applications of blockchain, and serve the transformation and upgrading of entity economy. 4. Actively build and improve the blockchain standard system, accelerate the development and application of key standards, and graally build a perfect standard system. Actively connect with ITU, ISO and other international standards organizations, substantially participate in more international standardization work, and actively contribute more "Chinese power". 5. We will accelerate the improvement of the policy environment for blockchain development, support qualified enterprises to carry out application innovation and mode innovation, and guide and encourage enterprises, universities and scientific research institutes to jointly cultivate professionals needed for blockchain development. Support eligible blockchain enterprises to enjoy the preferential tax policies of the state to support the development of software instry and small and medium-sized enterprises. The instrial scale is small but the growth potential is huge. The blockchain economy is on the eve of the outbreak period. The financial instry is relatively widely used, and the application of other instries has also entered the stage of exploration and development. It is estimated that the direct market value of blockchain will increase from US $410 million to US $7.68 billion between 2017 and 2022
2.
Because the digital currency, which is the first generation of blockchain technology, has a huge impact on the financial field, the research and application of blockchain technology has become an important task in today's financial field. In essence, blockchain technology still belongs to a kind of technical means and tools. Its application in the financial field and the real economy is parallel. It has its own relative independence, but it also has a certain degree of intersection. That is to say, its role in promoting the real economy is indirect
No matter finance or entity, trust is one of the basis of transaction between supply and demand. The current bank to enterprise, enterprise to enterprise and enterprise to person are all linked by money. With the further popularization and wide application of blockchain technology, enterprises and enterprises, or indivials can issue digital currency (Digital credit) by themselves in the future, and the status of banks will change from monopoly operation to equal competition operation in the market. Therefore, the wide application of blockchain technology in the financial field has an indirect impact on the real economy2. Blockchain technology is the bridge between reality (entity) and virtual world. Through blockchain technology, the real world can be reconstructed, reconstructed and redefined in the virtual world. For example, the digital currency of real paper money in the virtual world, the digital stock transaction of real stock transaction in the virtual world, the digital settlement, digital customs clearance, digital documents and bills of real import and export trade in the virtual world can greatly improve the efficiency of business process and save the transaction cost. At present, all transactions are inseparable from the bank. The bank plays a central role in the transaction. The application of blockchain technology by the bank will certainly improve the efficiency of its settlement and indirectly promote the efficiency of the real economy, but this impact will graally weaken in the future. Because the biggest feature of blockchain technology is decentralization, its distributed accounting system is a network system without center
3. The application of blockchain technology is actually to value and credit the current information flowing through the Internet. Through blockchain, the information with (use value, exchange value and cultural value) in the Internet is reorganized and reconstructed to form value Internet , which is of great significance, Whether it is to the financial instry or the real economy will bring revolutionary role in promoting

As a municipal Internet plus pilot enterprise, the Golden Bay network technology is the big data instry, and the deep block chain frontier technology is thoroughly explored to create an Internet innovation ecosystem with "block chain plus big data".
8. For your problem, its coverage is too large and profound! At present, the existence of QQ coin and all network virtual exchange items is to make the company
profitable, and its cost can not be superficial. Who knows or stipulates how much a hat and a dress in QQ embroidery are worth? How much do I sell
it is not the same as a real commodity
you need to estimate its value and how much benefit it can bring to employees. No matter how to determine its cost, it is also virtual. In principle, as long as I meet my
