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

Blockchain is on fire! It's so hot that I have no friends! In recent days, it has been swished by various popular science jokes of blockchain, just like crowdfunding, equity and original stocks in the past two years. If you go out and chat with others, you will be embarrassed to chat with others if you don't talk about blockchain. Textbook like explanation: an intelligent peer-to-peer network that uses distributed database to identify, disseminate and record information. It is a distributed database system with different nodes and an open ledger

the concept of "after the rules are settled, everyone will register spontaneously" in wechat organization corresponds to the concept of "decentralization, no single user can control it" in the blockchain. "Registration in wechat group" in wechat group corresponds to the concept of "peer-to-peer network" in blockchain. "As long as the network is connected, we can know the latest progress" in wechat organization Bureau, corresponding to the concept in blockchain, namely "game mechanism"

3. In short, blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. Blockchain technology enables all data in the database to be stored in all computer nodes of the system and updated in real time. The completely decentralized structure can record data in real time and update it in every network node participating in data storage, which greatly improves the security of database.

4. Blockchain is an important concept of bitcoin. In essence, it is a decentralized database and the underlying technology of bitcoin. Blockchain is a series of data blocks generated by cryptography. Each data block contains the information of a bitcoin network transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block
in a narrow sense, blockchain is a kind of chain data structure that combines data blocks in chronological order in a sequential way, and it can not be tampered with and forged by cryptography. In a broad sense, blockchain technology is a new distributed infrastructure and computing paradigm, which uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses intelligent contract composed of automated script code to program and operate data
both eurocrowdfunding and Ethereum use blockchain technology.

5. Man, you're not technology, are you; There are too many. All kinds of ghosts and ghosts come to evaluate the blockchain. Often, these people's understanding of blockchain is just superficial, even nonsense. I used to learn a little bit about technology development, but later I was afraid of being bald and started working in the media instry, although I found that there was still a risk of being bald after I joined the instry
to get down to business, let me analyze the routine of media platform from the perspective of media. A company needs a certain public opinion environment when it needs to develop, especially in emerging instries. What kind of things will media do for emerging instries? They will publish false reports and even malicious remarks about the instry. It's often the work of small media companies, so why do they do it? It's very simple to earn traffic. The most eye-catching is often the heated comments. This kind of articles can easily incite netizens' emotions and increase their reading volume. In this way, the flow of cash is a very simple thing, then the capital of advertising will become higher. The more vertical reports the article has, the more valuable the vertical ads will be. For example, if I am a we media practitioner and I have been making untrue comments about the blockchain instry, then one day a blockchain company wants to send a report to me, then I can ask for a price
most of the untrue comments on the Internet can be divided into several categories: the spread of falsehoods between small websites and small media. Rumors start from taking out of context and making up, and then they will be further upgraded. The first wave of taking out of context and making up articles will be used to intercept part of the evidence to spread the upgraded version of rumors. When many stars or company leaders see this, their first reaction is: when did I say this&# 160; The second reaction is to laugh. The media, alas, is normal. More helpless, spend money to find the media to explain it, another group of people said you wash white. Don't make a statement and say you acquiesce. This vicious circle wave after wave, some companies are not so destroyed? In view of the above content, I give the questioner a clear way to distinguish, first: pay attention to check the level of the media that issued the article, and be happy with what the small media say, but don't take it seriously. Second: is it released from its official platform? If not, no one knows so much inside information
from the perspective of technology, what's wrong with blockchain technology? It's just an emerging technology. In fact, it can't be counted. It was first applied to bitcoin. It's just that there is a delay for the general public to come into contact with these, just as it will take a few years for the routine model of big cities to develop into small cities. Columbus cat does have a certain strength in the technical circle, and its technical reserves are quite sufficient. Just want to achieve comprehensive business development, it will certainly need a long march. For example, we may have developed the online payment system long before Taobao came out, but the technology can not be applied immediately. First of all, you have to convince others to believe you, so that you can really apply it. Father Ma succeeded in persuading Chinese women, so he succeeded. Blockchain itself is a cross era technology. To better promote it, more dedicated entrepreneurs need to work together.
