Which country does the blockchain originate from

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

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

2. This is where the myth of bitcoin really takes over. According to legend, Satoshi Nakamoto, an unknown person, released an agreement on the digital point-to-point system of decentralized digital currency on October 31, 2008. I urge you to read this short and wonderful paper. While the idea behind bitcoin is revolutionary, it can now begin to make more sense in the context of all other systems, not all of them. Bitcoin proposed blockchain as a synchronous network to solve the probability consensus. According to BFT, from having less than 50% of the total network hash rate of Byzantine rivals Security is achieved in different ways than other historical protocols. Blockchain is designed to support availability rather than consistency, and can support thousands of distributed nodes. The cost of decentralization is much lower throughput in terms of transactions per second (TPS).

3. All departments in the United States actively strive to lay out blockchains. The Department of justice held a digital currency summit. The stock exchange has approved the company's stock trading on the blockchain. The commodity futures trading commission of the United States regulates the blockchain and treats bitcoin as a bulk commodity; In addition, the UK released distributed ledger Technology: beyond blockchain; Russia put forward "block chain technology development roadmap"; Australian central bank wants to issue data currency; Japan held a special research conference on blockchain; The Central Bank of Korea issued the status quo and Enlightenment of distributed ledger technology and digital currency< On January 20, 2016, the Central Bank of China said that it would launch legal digital currency as soon as possible; In July of the same year, the Ministry of instry and information technology issued the letter on organizing and carrying out research on the development trend of blockchain technology and application; On August 11, the Ministry of instry and information technology issued a two-year plan for blockchain.

4. Australia, Japan and Canada are all developing well. For example, in Japan, even the government has begun to apply the blockchain technology. Some of their government affairs, such as government bidding, are completed on the blockchain platform. There are also high-quality blockchain government affairs platforms in China, such as the blockchain rental platform in xiong'an New District of Hebei Province, the blockchain government affairs platform in Chongqing, and the SMIC blockchain public service platform in Changsha of Hunan Province. They have done well and achieved good results.

the definition of blockchain

in a narrow sense, blockchain is a kind of chained data structure that combines data blocks in a sequential way according to the time sequence, and it is a distributed account book that can not be tampered with and forged by means of cryptography

broadly speaking, blockchain technology uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, and uses cryptography to ensure the security of data transmission and access It is a new distributed infrastructure and computing method to program and operate data by using intelligent contract composed of automated script code

there are many channels to learn blockchain

① you can buy some books related to blockchain, learn some knowledge related to blockchain, take notes in your spare time, and consult relevant information

② watch some videos of blockchain on the Internet, the contents of which are easy to understand, with relevant examples, It's also a very good way to learn

③ you can take part in some offline blockchain learning exchange meetings, or take part in some training courses, and some teachers will answer questions for you

to sum up,

all roads lead to Rome. There are many channels to learn blockchain, and the best one is suitable for you

7. Yes, it's true. Ant blockchain takes advantage of the characteristics of non tampering, non repudiation, and easy traceability to provide businesses with one-stop online self-service, such as "image theft and rights protection" tool, que, which provides picture right confirmation, infringement forensics, evidence verification, and so on. The evidence meets the judicial recognition standards. In short, right protection information can be registered on the chain in one second to form reliable electronic data evidence. These sellers are no longer worried about being infringed, once infringement can quickly safeguard their rights.
