analysis of instrial chain of blockchain instry
Original title: China's blockchain instry market status and development trend analysis in 2019, widely used to accelerate the construction of Digital China. Basically, a relatively mature instrial chain has been formed. With the promotion of national policies and the increasing demand of downstream application fields, the market scale of China's blockchain instry is constantly developing, the regional concentration is high, and the instrial cluster effect is obvious. With the increasing maturity of blockchain technology, the blockchain instry is entering the 3.0 stage as a whole. It has a good performance in finance, logistics, right protection and other fields, and has made great contributions to promoting China's digital construction and accelerating the process of Digital China
instrial chain analysis of blockchain instry: there are many downstream application fields with huge development potential
from the perspective of instrial chain, China's blockchain instry includes upstream hardware, technology and infrastructure; Midstream blockchain application and technical services
application fields of downstream blockchain. The upstream hardware, technology and infrastructure mainly provide the necessary hardware, technology and infrastructure support for blockchain application. The hardware equipment includes mining machinery, ore pool, chip manufacturer, etc; General technologies include distributed storage, decentralized transaction, data service, distributed computing and other related technologies
the downstream application fields include the combination of application blockchain technology and existing instries, mainly including financial instry, logistics instry, right protection, medical health, instrial energy and many other fields. As an emerging technology, blockchain has many downstream application fields and great development potential
the application and service of midstream blockchain includes the construction of infrastructure platform and the provision of technical service support. The construction of infrastructure platform is divided into general infrastructure chain and vertical domain infrastructure chain; Technical service support includes technical support and service support.

instry chain analysis of blockchain instry Most of 360 and other enterprises use their own financial companies to apply blockchain technology to launch a new mode of blockchain + finance and broaden the application scenarios of blockchain technology
With the continuous development of China's blockchain technology and the continuous expansion of blockchain application fields, China's blockchain instry will become the forefront of global technology development and open up a new international competition track in the future2. Blockchain has become a new hot spot for innovation and entrepreneurship, and technology integration will expand new application space
3. Blockchain will be widely implemented in the real economy in the next three years and become an important support for the construction of Digital China
4. Blockchain creates a new platform economy and opens a new era of sharing economy
5. Blockchain accelerates the process of "credible digitization" and drives finance to "move from virtual to real" to serve the real economy
The blockchain supervision and standard system will be further improved, and the instrial development foundation will continue to be consolidated(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
in the future, jinwowo will continue to tap the value of blockchain technology in the commercial field.
There are many applications of blockchain, which can be summarized in the following figure:
Blockchain Instry Yearbook is a comprehensive and informative large-scale tool book that comprehensively reflects the development of global blockchain instry, and has been published continuously year by year The blockchain Instry Yearbook is based on the continuous observation and research of the global blockchain instry, as well as enterprise interviews, media docking, and employee research, which makes a detailed division of the current mainstream blockchain instry ecosystem. The Yearbook covers 12 categories of blockchain ecological content, including global blockchain people, media, applications, institutions, ecation, instrial parks, capital, exchanges, supercomputing services, tools, underlying public chains, and technical services. Yearbook is of great significance to meet the needs of global governments, enterprises and employees for information of the blockchain instry, and to make up for the lack of information of the global blockchain instry< br />
blockchain has the characteristics of decentralization, point-to-point transmission, transparency, traceability, non tampering, data security, etc., which can be used to solve some pain points of existing business and realize the innovation of business model. In essence, blockchain is a robust and secure distributed state machine. The typical technical components include consensus algorithm, P2P communication, cryptography, database technology and virtual machine. Its five essential core capabilities are data storage, shared data, distributed, tamper proof and privacy protection, and digital contract
the number of blockchain projects established in China has increased year by year since 2013, and decreased in 2017 e to policy supervision and other reasons, but the number of investment and average integration amount have graally increased.
