What are the core concepts of 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

Application of blockchain Finance:

Since 2017, the concept of blockchain, which has been popular all over the society and the world, is still heating up, attracting people and social funds; Boost bitcoin, as well as similar network "encrypted digital currency" (such as ether coin, Wright coin, etc.) price rise, created a lot of "overnight rich" myth. The argument that digital currency and blockchain will subvert tradition and profoundly change the world is constantly rising. The start-up and development of blockchain seems to be coming like a roaring sea, but it is more and more concentrated in coin making and speculation, and more and more trapped in the thinking and paradigm of "bitcoin blockchain" of mining and coin making
in the case that bitcoin must be exchanged with fiat money and must join the network trading platform and other auxiliary links in order to play a greater function, the characteristics of bitcoin blockchain such as area center and disintermediation may have serious problems. In the real world, if the transfer of monetary assets is operated through the bitcoin blockchain system, it will actually increase the intermediary link rather than disintermediation. Moreover, because the bitcoin system is highly anonymous and deliberately evades supervision, it is difficult to fully meet the requirements of anti money laundering and anti-terrorism transportation. On the contrary, many new serious problems may arise, Many arguments about bitcoin and blockchain are difficult to hold
those unseen pain points
the so-called labels of bitcoin blockchain, such as "decentralization", "democracy, equality and freedom", can not stand scrutiny; The truth is that if it puts too much emphasis on "decentralization", it will affect efficiency; Bitcoin has not yet become a real currency; The ICO type fund-raising method is not concive to the development of blockchain... But when people enthusiastically pursue blockchain like faith, they can not see these "pain points":
first, bitcoin blockchain is difficult to build a decentralized, democratic and equal society
bitcoin blockchain system envisages the establishment of an equal and democratic world for all participants, but in fact, the core team of coding maintenance and the main forces involved in mining and operation are not so equal and democratic. Due to the influence of computer computing power, the mining and acquisition of bitcoin are not equal as advertised. As a result of competition, the opportunities of mining and acquiring bitcoin are more and more concentrated on a small number of mining pools or nodes with powerful computing power. However, more and more people are involved in mining, consuming resources, but they may not be able to obtain bitcoin. This makes bitcoin more occupied by a few people, and will enhance its voice or influence on the adjustment of network rules
secondly, there are strict conditions for bitcoin blockchain to "de trust" and "de mediate" point-to-point transactions
