How many people are involved in blockchain in China

1. Neo
quantum chain

In the past, when it comes to blockchain, we always think of foreign procts, such as Ethereum. But when I talk about this topic today, I think more about China's own blockchain technology

at present, the mature application of blockchain technology is more concentrated in some public chain projects, because many application projects need to be developed based on this, so I think the current global landing direction is public chain projects, and it is still too early to talk about maturity. After all, bitcoin and Ethereum are still blocked, and many old problems have not been solved, There will be many new problems. The well-known ones are Biyuan chain, ulord (the project is abroad, but the technical party provides it in the domestic company, Hunan Tianhe Guoyun Co., Ltd.), quantum chain, Xiaoyi Neo, gongxinbao, etc

ulord is a point-to-point value delivery public chain. By building the underlying architecture of blockchain and digital resource distribution protocol, it supports third-party developers to build their own applications on top of their open source protocol, and works with many instry partners to build a complete ecosystem of blockchain technology and applications

based on various rules and protocols created by ulord, it is convenient to graft various digital resource application scenarios including text, pictures, music, video, software, etc., providing a direct docking platform for information creators and consumers. Third party developers can build their own economic system in ulord, or focus on building all kinds of applications around ulord, and use the ulordtoken in ulord as the voucher in the system

for example, an experience sharing platform can be built on ulord, where the experience sharers price the published experience, and the people who obtain the experience information trade on the platform, and each fee paid to the experience sharers will arrive at the account immediately; Proct promoters can publish ads on ulord, price ads, and people who are interested in ads can get certain profits by clicking on ads. The first mock exam is to separate information from the past, and to use platform or other centralized organizations to spread profit. This mode eliminates intermediate links, and information providers and consumers directly connect with Ulord, which ensures the maximization of the interests of the originator. p>

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.

1. Jinrong China Financial Instry Co., Ltd.

this is a digital currency trading platform in Hong Kong. At the beginning of trading, it developed on the principle of safeguarding the rights and interests of customers. Similarly, in order to expand trading customers, the company launched the privilege of opening accounts free of charge, and gave customers some concessions in some festivals, This is an important reason why the enterprise takes the first place in the domestic formal blockchain platform

2. Bitfinex

is a digital currency trading platform in Hong Kong, China. It is one of the largest cryptocurrency exchanges in the world. It occupies an important position in the world's cryptocurrency trading and circulation. It also provides the world's most liquid registration policy and plays an important role in the world's trading operations, At present, it occupies the second place in the domestic regular blockchain platform

3. Fire coin network

this is an earlier digital currency trading platform in China, mainly trading bitcoin. As the third instry of domestic regular blockchain platform, it is the trading platform with the largest bitcoin trading volume in China. Many new digital asset trading platforms have been developed under the company, For the future development of the foundation

This is a digital currency trading platform jointly established by some digital currency enthusiasts, and its founder is Zhao CHANGPENG. In fact, this trading platform didn't attract much attention at the beginning. With the continuous operation of the company and the founder's understanding of digital currency, this enterprise has become the top four domestic regular blockchain platforms, which shows the power of this platform

This is one of the most popular digital asset trading platforms in the world. There are many kinds of digital currencies for trading, and their main functions are cash out and derivative trading. They are well-known in the world's exchanges

5. Blockchain mainly solves the trust and security problems of transactions, so it proposes four technological innovations to solve this problem:
(1) distributed ledger, that is, transaction bookkeeping is completed by multiple nodes distributed in different places, and each node records complete accounts, so they can participate in monitoring the legitimacy of transactions, At the same time, they can testify together
different from traditional distributed storage, the uniqueness of distributed storage of blockchain is mainly reflected in two aspects: one is that each node of blockchain stores complete data according to block chain structure, while traditional distributed storage generally stores data in multiple copies according to certain rules. Second, the storage of each node in the blockchain is independent and has the same status, which relies on the consensus mechanism to ensure the consistency of storage, while the traditional distributed storage generally synchronizes data from the central node to other backup nodes[ 8]
no single node can record the account data separately, so as to avoid the possibility that a single bookkeeper is controlled or bribed to record false accounts. In theory, unless all the nodes are destroyed, the accounts will not be lost, so as to ensure the security of the account data
(2) asymmetric encryption and authorization technology, the transaction information stored on the blockchain is public, but the account identity information is highly encrypted, which can only be accessed under the authorization of the data owner, thus ensuring the data security and personal privacy
(3) consensus mechanism is how to reach a consensus among all accounting nodes to determine the validity of a record, which is not only a means of identification, but also a means of preventing tampering. Blockchain proposes four different consensus mechanisms, which are suitable for different application scenarios and achieve a balance between efficiency and security
the consensus mechanism of blockchain has the characteristics of "the minority is subordinate to the majority" and "everyone is equal", in which "the minority is subordinate to the majority" does not completely refer to the number of nodes, but also can be the computing power, the number of shares or other characteristics that can be compared by computers“ "Everyone is equal" means that when the nodes meet the conditions, all nodes have the right to put forward the consensus results first, and then directly recognized by other nodes, and finally may become the final consensus results. Taking bitcoin as an example, the workload proof is adopted. Only when more than 51% of the accounting nodes in the whole network are controlled can a nonexistent record be forged. When there are enough nodes in the blockchain, this is basically impossible, thus eliminating the possibility of fraud.
(4) smart contract, which is based on these trusted and tamperable data, can automatically execute some pre-defined rules and terms. Take insurance as an example. If everyone's information (including medical information and risk occurrence information) is true and reliable, it is easy to carry out automatic claim settlement in some standardized insurance procts

6. 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.

7. 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.

According to the report, based on the logic of equality and trust, blockchain tries to realize the security trust mechanism of "mutual trust" instead of "public trust" through technology with the characteristics of decentralization, non tampering and anonymity, and has graally become an important role in the field of fintech

the report also said that the open and tamperable properties of blockchain technology have the potential to change the financial infrastructure, and all kinds of financial assets can be integrated into the blockchain ledger to become digital assets on the chain, which can be stored, transferred and traded on the blockchain, making it a broad application prospect in the financial field

9. 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.
