How many people are doing blockchain in China

1. There are still many domestic enterprises that are actually doing blockchain technology, such as fun chain technology, Vientiane blockchain, energy chain group, complex US technology, Xinghe blockchain, Zhigui technology and medical chain group. They are all well-known enterprises with good technology in the instry. Internet giants basically have blockchain sections.

2. Shanghai's Wang chain technology is OK. They are the first enterprises to engage in blockchain technology and apply the technology to the actual instry. We can digitize every link of agricultural procts from proction to processing to retail, so as to make proct information open and transparent.

3. IBM, Microsoft, Oracle, Accenture, Tencent, Alibaba, Jingdong, network, etc. have all done it. Many large banks, including Ping An Bank, have also launched their own blockchain solution platforms or solutions. However, it should be added that large companies do not mean strong technical strength, because blockchain is still in the hot stage of concept in the world. Unicorn blockchain companies are likely to emerge in the future, such as EOS in foreign countries and honeycomb chain of Fanrong technology in China. The efficiency of TPS and packing into blocks may be much higher than that of large companies.

4.

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

5. Beijing, Fujian, etc. we also have a Changsha blockchain Application Technology Instry Association in Changsha. Recently, the SMIC blockchain launched by Changsha hi tech Zone is also operated by its member units.

6. Patents have always been controversial in the field of cryptocurrency and blockchain, because most projects are built on the premise of decentralization and open source. It is for this reason that the concept of intellectual property (IP) is highly controversial
for this purpose, the following search terms are used to collect the website data of the World Intellectual Property Organization (WIPO): blockchain, blockchain, bitcoin, virtual currency, virtual currency, digital currency, digital token and smart contract
the analysis found that although the price of bitcoin plummeted, 2018 was the year with the most patents approved, and records showed that at least 1060 patents were published ring this period

971 items were approved in 2017. In that year, bitcoin began trading at $998, reaching an all-time high of $19666 in December
according to the data, patent approval started to take off in 2012, and it remained at the same level until 2015. So far this year, the World Intellectual Property Organization has granted 242 patents related to cryptocurrency or blockchain
China ranks first with 790 patents
followed by the United States, which approved 762 patent applications. South Korea and Australia followed, 161 and 132 respectively. The UK is the only European country in the top 10 with 36 approvals

the companies on the list are mainly technology giants and financial service companies, such as IBM (119 items), MasterCard MasterCard (111 items), coinplug (84 items) and Alibaba (60 items)< Among them, Yao Qian, director of the digital currency Research Institute of the people's Bank of China, has obtained 92 patents.

7. There are at least 20 or 30 parks in Shanghai, Wuhan, Hangzhou and Changsha, but the vacancy rate of nearly 30% of the parks exceeds 50%. In fact, every park is increasing favorable policies to attract enterprises to settle down. Changsha high tech Zone has launched a medium core block chain service platform project, which is block chain + public service mode, and is recruiting enterprises to join the chain.
