Blockchain consumes memory

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

on December 2, 2019, the word was selected into the top ten catchwords of "biting words" in 2019

extended data:

Application of blockchain Finance:

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

Blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. Blockchain is an important concept of bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains a batch of information about bitcoin network transactions, Used to verify the validity of its information (anti-counterfeiting) and generate the next block

if such technology wants to be put into application, the biggest problem is the "Impossible Triangle problem"

that is, scalability, decentralization and security cannot be achieved at the same time, and only two of them can be achieved

most of the existing public chain projects in the market are difficult to put into use on a large scale

From District TV network Share: in 2018, blocklink bar AI has become the most popular technical term, and more and more technology companies have announced to enter the blockchain market. In the Internet, Xunlei, Renren, Fengfeng, Tianya and other companies have blockchain related actions. These companies share the same fate. They have all experienced prosperity, but after the impact of Internet entrepreneurship tide, they began to go downhill. Then they rubbed against the hot spots of blockchain and began to try to counter attack
Global blockchain instry investment is hot
according to the data of the "in-depth analysis report on business model innovation and investment opportunities of blockchain instry" released by prospective instry research institute, as of the end of April 2017, there were 455 blockchain companies in the world, with a total financing amount of US $1.947 billion. Among them, the total investment and financing of us blockchain related companies reached US $1.252 billion, accounting for 64.3% of the global market; The total financing amount of China's blockchain emerging enterprises is about US $114 million, accounting for 5.86%, ranking second in the world after the United States, and growing rapidly
at present, the overall survival status of blockchain is good, with a survival rate of 87.25%. Among all the invested companies, 47 have been closed, accounting for about 10.51%, and the other 10 have been acquired. Due to the change of competition pattern in bitcoin market, some companies have been forced to shut down. Meanwhile, some coin circle companies are graally transforming to chain circle companies.
exploration at the national level has also begun. On March 23, the information technology and Software Services Department of the Ministry of instry and information technology announced that it will study and explore the application of blockchain in the instrial field. Previously, the Ministry of instry and information technology said that it was preparing to establish a National Technical Committee for standardization of blockchain and distributed accounting technology to explore the formation of a complete blockchain standard system to better serve the development of blockchain technology instry
