What is the concept of blockchain and what is blockchain
blockchain is a term in the field of information technology. In essence, it is a shared database. The data or information stored in it is characterized by "unforgeability", "trace in the whole process", "traceability", "openness and transparency" and "collective maintenance". Based on these characteristics, blockchain technology has laid a solid "trust" foundation, created a reliable "cooperation" mechanism, and has broad application prospects
on January 10, 2019, the state Internet Information Office issued the regulations on the management of blockchain information services. In October 24, 2019, ring the eighteenth collective learning of the Central Political Bureau, general secretary Xi Jinping stressed that "block chain as an important breakthrough in core technology and independent innovation", "accelerating the development of block chain technology and instrial innovation". "Blockchain" has entered the public field of vision and become the focus of social attention

related extension: blockchain financial application:
since 2016, the major financial giants have also carried out blockchain innovation projects to explore the possibility of applying blockchain technology in various financial scenarios. In particular, Puyin group took the lead in creating a "blockchain +" standard digital currency
standard digital currency refers to the process of assets identification, evaluation, right confirmation and insurance completed by a third party organization, which is written into the blockchain through careful digital algorithm to form the standard corresponding relationship between assets and digital currency, which is called standard digital currency
in order to realize the great leap forward development of blockchain finance, promote the new development of China's economy, accelerate the circulation of global assets, and realize the dream of rejuvenation that has been struggling for generations, Puyin group will hold the Guiyang strategic development ceremony of Puyin blockchain finance in Guizhou on December 9, 2016
the meeting will discuss the realization of digital circulation of assets by blockchain, the financial transaction mode of blockchain, and the application of blockchain services and social public instry. This conference will mark the beginning of the application of blockchain finance and the change and development of the new financial ecology
on June 1, 2020, Xinhua news agency was authorized to broadcast the "overall plan for the construction of Hainan free trade port" issued by the CPC Central Committee and the State Council, which will "actively participate in the formulation of international rules for cross-border data flow, and establish standards and rules for data rights confirmation, data trading, data security and blockchain finance" as one of the key tasks of Hainan free trade port before 2035
nowadays, the mainstream digital currencies are basically developed based on blockchain technology. Blockchain is the underlying technology of digital currency. The domestic tea based digital currency Puyin is developed based on blockchain technology.
blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system [1]
2. What is a concept
concept has two basic characteristics: Connotation and extension. The connotation of the concept refers to the meaning of the concept, that is, the unique attribute of the object reflected by the concept. For example: "goods are labor procts for exchange.". Among them, "labor procts for exchange" is the connotation of the concept of "commodity". The extension of the concept refers to the scope of the object reflected by the concept. That is, things or objects with attributes reflected by concepts. For example, "forest includes shelter forest, timber forest, economic forest, firewood forest and special purpose forest", which is to explain the concept of "forest" from the perspective of extension. There is an inverse relationship between connotation and denotation of a concept, that is, the more connotation a concept has, the smaller denotation it has; vice versa. A more understandable explanation: the connotation of the concept refers to the meaning of the concept. There are necessary conditions, that is, objective things (objective objects), among which there is only one necessary condition and N sufficient conditions. The more conditions, the smaller the extension of the concept. Conditions are functional. For example: the cup needs space to carry. And it is used to hold water, wine and other liquids. Moreover, it is a kind of utensils (the defined items cannot be directly or indirectly included in the definition items), so the meaning of the concept of cup is: utensils used to hold water, wine and other liquids. And if we know the sufficient conditions, we can roughly dece the things or objects. Because it must be connected with the objective things. The functions of concept include judgment, description, attribute, category, definition (conceptual clarity), etc
the description of concept in China is: concept is avant-garde, novel, trendy, with future trend, background and picture. The concept has the strict fixed content, also has the certain fuzziness. Concept is not real, but imaginary. We should use concept to think and use concept to show its authenticity. The pattern of consciousness is endless. The more thorough the images are, the better it will be for us to enter a fine and infinite field. Otherwise, one thing will always be reced to another
from the perspective of form: ideas are more advanced, concepts appear in the form of words, and ideas usually appear in the form of a complete sentence. But in the same form; They are all based on Chinese and symbols. Therefore, it can be understood that the concept is a brilliant idea that condenses more information. Therefore, the concept is imaginative and pictorial, while the scientific concept is systematic. Concepts must also be comprehensible, so they are universal and objective.
