Efficient application of blockchain Technology
Publish: 2021-05-09 01:54:29
1. The core advantage of blockchain technology is decentralization. It can realize point-to-point transaction, coordination and cooperation based on decentralized credit in a distributed system without mutual trust by means of data encryption, time stamp, distributed consensus and economic incentive, so as to solve the common high cost, low cost and low cost of centralized institutions Low efficiency and data storage insecurity provide solutions
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry
taking the tourism instry as an example, blockchain applications mainly focus on tourism travel, tourism community reviews, digital identity management, credit consumption management, tracking pilot's professional certificate and qualification, loyalty plan of hotels and airlines, reservation management and consumption points management. In addition, blockchain also has applications in finance, games, entertainment and other fields.

2. 1、 Decentralization:
blockchain technology does not rely on additional third-party management institutions or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, each node realizes information self verification, transmission and management through distributed accounting and storage. Decentralization is the most prominent and essential feature of blockchain< Second, openness:
the foundation of blockchain technology is open source. In addition to the private information of all parties to the transaction is encrypted, the data of blockchain is open to all. Anyone can query blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent< Third, independence:
based on consensus specifications and Protocols (similar to various mathematical algorithms such as hash algorithm used by bitcoin), the whole blockchain system does not rely on other third parties, and all nodes can automatically and safely verify and exchange data in the system without any human intervention< Fourth, security:
as long as 51% of all data nodes cannot be controlled, the network data cannot be arbitrarily controlled and modified, which makes the blockchain itself relatively safe and avoids subjective and artificial data changes
5. Anonymity:
unless there are legal requirements, technically speaking, the identity information of each block node does not need to be disclosed or verified, and information transmission can be carried out anonymously
Digital China is the first major development strategy explicitly put forward in the report of the 19th National Congress of the Communist Party of China. The application of digital technology represented by cloud computing, big data and mobile Internet is no longer limited to the economic field, but widely penetrated into all aspects of public services, social development and people's life, which requires macro coordination, overall control and integrated development
with the deepening of a new round of scientific and technological revolution and instrial change, the tide of digital economy in the world is unstoppable. The development of digital economy has become a global consensus, known as the key to the fourth instrial revolution
adhering to the connotation of the University of nice's world inclusive humanistic spirit, always embracing change, standing up to the tide, conforming to the development trend of the digital economy era, and integrating the essence of Chinese and Western cultural thinking, the University of nice's doctor of blockchain and digital economy management (DDE) came into being
based on this, we can enable the managers of digital economy instry to have global vision and global integration thinking, integrate knowledge, operate digital economy intelligently, promote the sustainable development of the instry, and contribute to the community of human destiny. Therefore, DDE project will cooperate with colleagues in the field of digital economy

3. Renren blockchain enterprise services, visual display, analysis, statistics, monitoring blockchain operation
analysis, statistics, monitoring and alarm of the overall running state of the system
visualization analysis, statistics and management of member organizations, nodes and account books
digital asset transaction into the chain, transaction information, block height query display, etc
at present, there are not many such companies. Because of the particularity of blockchain, only indivial companies in China can do it, not necessarily big companies, but only those who have really done blockchain landing projects, such as Renren chain.

5. First,
decentralized feature
as the name suggests, a blockchain does not need a centralized server, and all the information is stored on each node in the chain in a distributed form. Even if a node is damaged or tampered, the operation of the whole blockchain will not be affected, and the data will not be disordered
Second, consensus mechanism
consensus mechanism plays an important role in the trustworthiness of data on blockchain. Due to the decentralized architecture, any two nodes in the chain do not need to trust each other's identity to establish a connection, and there is no need to trust each other for data exchange. Since all nodes in the network can act as "supervisors", there is no need to worry about fraud. When a transaction is completed, all nodes on the blockchain will synchronize this information, so the consensus mechanism is based on the distributed architecture to ensure the data can not be tampered with
Third, smart contract
before we talk about blockchain + smart contract, let's first clarify the meaning of smart contract: a set of commitments defined in digital form, on which contract participants can implement these commitments. Generally speaking, it is a smart contract. In a computer system, when certain conditions are met, the contract can be executed automatically.

6. The core technology of Chongqing jinwowo network analysis blockchain:
the core of blockchain is to establish appropriate consensus mechanism and good governance mechanism
it is difficult to establish a new consensus mechanism in philosophy and technology. Now the mature consensus mechanism is POW
, which is a consensus mechanism based on workload proof.

7. 1-blockchain can drive the birth of a new business model
the characteristics of blockchain technology enable it to achieve some business models that are difficult to achieve in the centralized mode
2 - blockchain technology has a flexible architecture
according to different application scenarios and user needs, blockchain technology can be divided into public chain, private chain and alliance chain, which can be selected according to the actual use of institutions
the openness of 3-chain technology encourages innovation and collaboration
through the opening and cooperation of source code, blockchain technology can promote the cooperation among different developers, researchers and institutions, and learn from each other, so as to achieve a more efficient and secure solution
jinwowo will use blockchain technology to fully record big data sources and improve storage.

8. The core of blockchain technology
is consensus algorithm. The essence of consensus algorithm is to form a game field of
Nash equilibrium
in
distributed network
under the condition that each node does not trust each other, and to win the trust of all parties, quickly reach an agreement between each node, and complete the task synchronously.
