Blockchain teaching node College

1. Do you want to learn blockchain development technology or just want to know what blockchain is? If it is the former, you can look at the code of other blockchain projects and learn about it first. If it is the latter, we can pay attention to some good blockchain we media. Blockchain is an emerging instry. There is no ready-made training course. It depends on self exploration and understanding.

2. Nodes are the places where the blocks are connected, and the blocks need to be chained to be useful
core analysis:
1. Transparency, 2. Openness, 3. Information can not be tampered with, 4. Decentralization,
5. Detailed analysis
blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system
1. In a narrow sense, blockchain is a kind of chained data structure composed of data blocks connected in sequence according to the time sequence, and it can not be tampered with and forged by cryptography
2. 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.

3. Relevant blockchain technology applications have also been quietly added to the live scene. Some experts have shown that the future blockchain will be closely related to people's lives, and the integration of blockchain technology and people's daily life is the general trend
the popularity of the blockchain market has caused a large number of talents demand based on blockchain technical personnel, and the popularity of blockchain talents is rising at the speed of light. According to the "2018 blockchain high salary list" released by lagou.com, Tencent, Xiaomi, Suning, Jingdong and other domestic enterprise giants have released many high salary blockchain post demands, trying to explore blockchain related technologies and applications. It is also pointed out in the list that the demand for high salary jobs is mainly based on blockchain related technical jobs, among which Suning and Keda have been given the highest monthly salary of 100k
the huge market demand for technical talents will inevitably lead to the explosive emergence and growth of the whole blockchain training market. Most of the training modes can be divided into online training, traditional IT organization training, and offline short-term training camps, which mainly focus on high-end forms. However, in the process of the hot market evolution, there are also a variety of blockchain training chaos: lecturers' qualifications are watered down, and even the most basic names are not disclosed, the syllabus is opaque, and the teaching quality is shrinking, Unreasonable class arrangement and uneven training fees and so on
in the first stage, go language foundation and network concurrency will be completed in 4 weeks, and then the introctory go language will be learned.
in the second stage, go language will be used for practical web development, crawler development, cryptography, consensus algorithm, and lightweight public chain will be realized, and the website and crawler that can develop golang will be completed, and lightweight block chain will be realized.
in the third stage, Ethereum source code analysis and intelligent contract DAPP development will be completed in 4 weeks, After learning and mastering Ethereum core and smart contract development, as well as blockchain,
phase IV 4-week super ledger, bitcoin EOS, source code analysis and smart contract practice, after learning and mastering super ledger development, Shanzhai bitcoin, bifurcated EOS, and smart contract DAPP development
phase V 6-week project practice, five enterprise level projects, One year of blockchain project experience after learning

4. Well, there are still many institutions. We recommend Guoxing blockchain business school, which is regular. If you need it, you can find it.

5. Blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies[ 1]
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 the information of a batch of bitcoin network transactions, Used to verify the validity of its information (anti-counterfeiting) and generate the next block[ 2]

6.

With all walks of life have begun to enter the blockchain instry, blockchain has undoubtedly become the world's largest wind in 2018. Since 2014, more than a dozen top universities in Europe and America, including MIT, Stanford University and Princeton University, have successively opened blockchain courses

now, it is no longer limited to the teaching of blockchain technology, and some people are ready to challenge the traditional ecation mode with blockchain technology. According to the times of higher ecation, a group of scholars from Oxford University announced that they would establish the world's first blockchain University, Woolf University

{rrrrrrr}

Course Platform demo according to the official website of Woolf University

actively promote the block chain credit certification

"hope the degree certificate will be widely recognized in the future"

however, there are no doubt many problems to be solved when applying an emerging technology to a new concept. Professor Michael sharens, a professor at the Open University of the UK, said that although the founding of Woolf university is a subversive force in the field of ecation, how to ensure high standards of teaching is a big problem. Although blockchain can ensure the teaching interaction between teachers and students, it can not guarantee the quality of teaching

in this regard, Dr. blocky told the media that the key to the quality of ecation is not whether there is a physical campus, but the ability of teachers. Of course, the school will also have relevant teaching quality supervision measures. First of all, only scholars with real doctoral degrees can join the platform as teachers, and they must upload certificates for verification

secondly, the top five colleges of the university will be composed of scholars with doctoral degrees from world-class universities. After the establishment of five high-quality colleges, Woolf will be open to other scholars one after another

in addition, a ranking system was established among colleges according to the number of teaching and the average score of students. Finally, the university will set up a review system for academic fraud and cheating, which will be regularly reviewed by the dean of the college

then, in addition to ensuring the quality of teaching, how can the academic records of blockchain obtain formal academic recognition

Dr. brocky said that blockchain can help the credit certification process, because the information records it provides are highly accurate and completely reliable. The European Commission has recently published a report on blockchain in ecation, but it will take some time to complete this process

before obtaining official permission, blockchain records will be temporarily used as a part of the application process. For the degree certification of early-stage students, the university will cooperate with existing universities and still use the traditional way to certify credits. In addition, at the initial stage of its establishment, the university will invite ecational institutions such as Oxford college to join the platform and make full use of their existing degree certification mechanism. At the same time, the University of Virginia Woolf has begun to actively seek ecation certification in the European Union and the United States, hoping that in the next 10 years, the degree certificate of Virginia Woolf University will be widely recognized

Dr. blocky said that Woolf university is the future ecation model, which combines online and offline ecation, and connects the world's outstanding students and teachers by building a global talent network“ I hope this model can improve the overall quality of ecation and provide a new way for students to acquire knowledge and achieve success, no matter where they are

7. There is no specific measure. But we can choose from several aspects:

8. I think Guoxing blockchain business school is really good, which can improve the competitiveness of enterprises and help enterprises.

9. The currency of ancient China has a long history of using currency in China, which has graally developed into a unique style of currency culture in thousands of years of historical evolution, and has had a great impact on many surrounding countries and regions

it is generally believed that in the Xia and Shang Dynasties, China had money. The earliest currency in China was mainly physical currency. At that time, the currency with the widest circulation, the largest quantity and the longest time was shellfish. Shell, smooth and beautiful, strong and wear-resistant, easy to carry, easy to count. There are a large number of shells unearthed in the sites of Xia and Shang Dynasties, and there are also records about shells in the ancient documents of Shang and Zhou dynasties. In Chinese characters, most of the characters related to value begin with "Bei"

with the rapid development of commodity exchange, the demand for money is increasing, and seashells can not meet people's demand. In the late Shang Dynasty, people began to imitate seashells with copper, and bronze imitation became the earliest metal coin in China. With the extensive use of coinage by workers, seashells, as a kind of natural currency, graally withdrew from China's currency stage. From the appearance of Tongbei in Shang Dynasty to the Warring States period, e to the dominance of vassals, China's currency graally formed four unique currency systems, namely shovel coin, Dao coin, ring coin and Chu coin (yuan Jin and Yi Bi Qian)< After the unification of China by Qin Dynasty, the first emperor of Qin Dynasty promulgated the earliest monetary law of China in 210 B.C., which abolished the formal currency of various countries and designated gold and copper as the unified currency. Gold was used to pay for large transactions, while copper money, half of the round square hole of Qin, was used in daily life. The circulation of Qin banliang coins with round square holes in the whole country ended the disordered state of different shapes and great weight differences of ancient Chinese coins, which was a significant evolution from disordered shape to standard shape in the history of ancient Chinese coins. The shape of this round square hole determined by the Qin banliang coins continued until the early Republic of China

Emperor Wu of the Han Dynasty regained the minting right of the prefectures in the fifth year of Yuanshou (118 BC) and minted five baht coins by the central government. On the surface of the round square hole, the word "five baht" was cast, which determined the unified management of coin casting and issuance by the central government. Wuzhu money has been used in the period of emperor Gaozu of Tang Dynasty for more than 700 years. It is the longest used and most successful currency in ancient China< In 621, Li Yuan was determined to reform the currency system, abolish the five baht coin, and cast "Kaiyuan Tongbao" coin“ The four words "Kaiyuan Tongbao" were written by Ouyang Xun in the early Tang Dynasty. The so-called "Kaiyuan" means to create a new era, while "Tongbao" refers to the general treasure in a unified country. Kaiyuan Tongbao is a reverse of the old system of Qin and Han Dynasties. The weight of money is not written in the text (the weight of money is usually clearly indicated in the text of money since Qin and Han dynasties). It is the evolution of ancient Chinese money from the weight of documents to Tongbao and Yuanbao. Kaiyuan Tongbao coin is the earliest Tongbao coin in China. It was cast in July of the fourth year of Wude (621 A.D.) in Tang Dynasty. It has a history of about 300 years and has never been interrupted. This is also rare in the history of currency. Since then, copper coins in China no longer use money to mark the weight, but use Tongbao and Yuanbao. It has been used until the "Tongbao of the Republic of China" after the 1911 Revolution

the "Kaiyuan Tongbao" in the Tang Dynasty ushered in a new era in the monetary history of China. From then on, the bronze coinage broke away from the tradition of renaming with banliang and wuzhu, and began to transform to abstraction and symbolization“ "Kaiyuan Tongbao" also sets up the standard image of Chinese currency in shape and weight. It takes one coin as the legal weight unit, and weighs one or two for every ten coins. The decimals of ten yuan or two came into being and had a profound influence on later generations

in the Northern Song Dynasty, e to the shortage of copper materials, there was a shortage of money. In order to make up for the shortage of copper money, the government cast a large number of iron coins in some areas, and iron coins and copper coins coexisted. According to the records of the history of Song Dynasty, the cast iron coins in Sichuan at that time always weighed 25 Jin and 8 Liang. To buy a piece of silk in Sichuan, you have to pay 130 Jin of iron. Iron money is so heavy and inconvenient that paper money "Jiaozi" came into being in Sichuan“ Jiaozi uses a unified paper, has a certain shape, is printed with complex patterns, and has anti-counterfeiting secret records“ The appearance of "Jiaozi" is an important evolution from metal currency to paper currency in ancient Chinese currency history“ Jiaozi is not only the earliest paper currency in China, but also the earliest paper currency in the world

Kublai Khan, the emperor Shizu of the Yuan Dynasty, established a unified banknote system and issued "Zhongtong Yuanbao banknotes", which made the Yuan Dynasty the first dynasty to adopt a unified banknote as its basic monetary system< In the early Ming Dynasty, silver was not a legal currency, and gold and silver trading was forbidden. During the reign of emperor Yingzong of Ming Dynasty, the ban on using silver was lifted. So far, silver, as a currency and a measure of value, officially gained its legal status. In the late Ming Dynasty, silver was popular in the whole society and occupied a dominant position in the field of currency circulation

in the first 100 years of the Qing Dynasty, the ingot shaped silver ingots cast in the late Ming Dynasty were still used in various places. At that time, there were various shapes and qualities of silver in circulation on the market. Those weighing less than one or two were called scattered silver pieces, while those weighing from one or two to five Liang were called small pieces, which were used for general trading; For bulk trading, it is a kind of national fake standard silver, which weighs about ten liang of ingots and fifty liang of Yuanbao. When paying, it must be converted into silver and then converted into pure silver, so as to complete the exchange of value for money. It is very inconvenient to use

before and after the outbreak of the Opium War, foreign silver dollars were successively imported into the mainland of China. There were dozens of silver dollars in circulation in the local market, such as Benyang in Spain, Ma Jianyang in the Netherlands, zhanrenyang in Britain, Yingyang in Mexico, Longyang in Japan, etc. As foreign silver counts the value of a piece, it is not necessary to weigh it when it is used, so the people are willing to accept it. For most of the 19th century, it became a choice of currency in China, and also became the catalyst of China's self casting silver dollar. In the years of Daoguang and Xianfeng, imitation silver rose from coastal cities with frequent trade with foreign merchants, and then spread to all parts of the country. It is called Guangban in Guangzhou, fuban in Fuzhou and Hangban in Hangzhou. Among them, the one supervised by Shanghai Daotai is the most regular, with the weight roughly in line with foreign silver dollars. In this situation, in order to maintain national dignity and maintain the monetary system, the Qing government began to plan to cast its own silver< During the reign of Guangxu, Zhang Zhidong, the governor of Guangdong and Guangdong provinces, founded the Guangdong money Bureau in Guangzhou, bought British machines and began to cast silver yuan called Guangxu Yuanbao, which was worth 1 million yuan that year. This is the beginning of China's official casting of silver dollar by machine, and also the origin of modern monetary unit system. The back of Guangxu Yuanbao is decorated with flat dragon pattern, which is also made of imitation silver, so it is called Longyang. After that, the Qing government set up a general foundry of silver coins in Tianjin to manufacture silver coins. The emergence of mechanism currency in the late Qing Dynasty is an important evolution from hand coinage to machine coinage. From then on, not only did great changes take place in the process of casting coins, but also the round square hole coins that had been in circulation for more than 2000 years died.

10. It's a blockchain information website, which has a lot of the latest blockchain information. The content is very rich
