< H2 > reference: network leading stocksBlockchain 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
digital currency and virtual currency are actually different names. They are tokens issued based on blockchain technology. Behind them are a series of computer-generated complex codes. At present, there are thousands of digital currencies in the market. The safest and most powerful digital currency is bitcoin
digital currency is also a high-risk and high return investment proct, through appropriate investment strategies, you can get rich returns. If you have spare money, you might as well put some of it into the digital currency. There will be unexpected surprises.
10x + 5 (45-x) = 350
10x + 225-5x = 350
5x = 125
x = 25
so 10 yuan is 25 pieces, 5 yuan is 20 pieces.
for example, the traceability of procts. For example, we buy a box of West Lake Longjing tea. If this box of Longjing tea applies blockchain technology. We can trace the origin of tea proction, a mountain in Hangzhou, a teahouse, from the picking process, proction to the circulation market to the hands of consumers. In this way, we can ensure that the procts we buy must be authentic West Lake Longjing. This is a very big value of blockchain in the traceability level of procts
As for this question, I suggest you go to lobby the community to have a look (web link), where there are big guys and big V to answer for you. Here I share with you an article by Mr. Ruan Yifeng, which should be able to answer your questions
I. what is the essence of blockchain? In a word, it is a special distributed database
the current rule is that new nodes always use the longest blockchain. If there is a fork in the blockchain, we will see which branch is behind the fork point and reach six new blocks first (called & quot; Six confirmations. According to the calculation of a block in 10 minutes, it can be confirmed in one hour
since the generation speed of new blocks is determined by computing power, this rule means that the branch with most computing power is the authentic blockchain
9. As an unmanaged distributed database, blockchain has been running for 8 years since 2009, and there is no big problem. This proves that it is feasible However, in order to ensure the reliability of data, blockchain has its own costs. One is efficiency. When data is written to the blockchain, it takes at least ten minutes. If all nodes synchronize data, it takes more time; The second is energy consumption. The generation of blocks requires countless meaningless calculations by miners, which is very energy consumingtherefore, the application scenarios of blockchain are very limited
there is no management authority trusted by all members
the data written by
does not require real-time use of
the benefits of mining can make up for its own costs
if the above conditions cannot be met, then the traditional database is a better solution
at present, the biggest application scenario (and possibly the only one) of blockchain is cryptocurrency represented by bitcoin
