What is the Department of blockchain

1.

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

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

Although the blockchain technology is still in the early stage of development, the corresponding talents are in short supply

Computer (software engineering, information and computing science, information technology, information security, etc.)

2, mathematics related majors

3, economics related majors

4, cryptography

at present, various well-known institutions around the world are competing to launch blockchain teaching courses, Some universities have even set up corresponding completion certificates for blockchain courses

3. You search the blockchain Business Revolution & ZWJ; Life, G & ZWJ; oj‍ Oy blockchain Network & ZWJ; University courses, the relevant knowledge explained very clearly.

4. 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". It is of great significance to the development of enterprises. They can learn the knowledge of blockchain in huocoin University. At present, they have launched the online live course, which covers the instry trend, cutting-edge technology, application mode, digital finance and other fields.

5. If you are interested in blockchain technology, you can learn the knowledge of cryptography at the beginning, and learn how to strengthen contracts other than trust through numbers. This is the most basic principle of blockchain. Then you can look at the programming books, understand the basic code, and do simple programming. After that, you can download some common blockchains, Study its code arrangement, see how it adds contracts, and make simple modifications to build its own smart contracts. Of course, if you are only affected by the recent price and hype and decide to join the instry, I suggest you learn more about the Bulls who hype it, listen to their opinions, and learn how others reap!

6. Blockchain is a new application mode of computer technology, such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and so on. As an important concept of bitcoin, blockchain 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 bitcoin network transaction information, which is used to verify the validity of the information and generate the next block
this is a passage in Alibaba's documentary dreamer. When ps: is repeated many times, it can explain the term "third parties" very well. This is also the beginning of Taobao and Alipay's birth. In other words, at that time, Ali was forced to act as a "third party" because no company could play such a role, so Ali became a center of trust. Businesses and users chose to give money to Ali because of "trust". But what if Ali absconds with money (though impossible...) or if the financial operator has problems (after all, it's human...)? If only there was a machine or a "super system" to do these things! Today, more than ten years after the replacement of Internet technology, blockchain appears in front of us, right! It's the super system;! A machine of trust
with blockchain, things start to change
traditional centralized mode:
decentralized mode under blockchain network:
in decentralized network, each user can be directly contacted without any third party's participation, and the transfer between users is like hand-in-hand cash, which is why bitcoin is called "e-cash"
well, now that a has transferred the money to B, who will charge the account? Alipay has helped me keep account of accounts, which will be unified in Alipay backstage system. In order to make all the transactions of the users recorded and the accounts are correct, Alipay will make great efforts to this end. Look at Alipay's initial
1000 bills per day. Artificial reconciliation is already very painful. With the volume of Alipay now, there are less than hundreds of thousands of bills per day, even if the system reconciliation is unavoidable, and it is necessary to pay the corresponding manpower and material resources to maintain this very complex revenue and expenditure clearing system. Having said so much, how does the blockchain reconcile? The answer is: no! There is no need for reconciliation and zero clearing in the blockchain network, because every node in the blockchain (a computer or a user) has its own account book, which is updated in real time. Any transaction in the blockchain network will be recorded in your own account book. Yes, you also have other people's accounts, But you don't know who this person is, because they all look like this:

7. Cheng University of information engineering, the first blockchain engineering major, blockchain is still very popular. The SMIC blockchain platform launched by Changsha high tech Zone also enlists enterprises to go on the chain, and then enterprises can make transactions on the chain.
