Recently, a blockchain recruitment advertisement in Beijing has burst the circle of friends, requiring candidates to have in-depth research on blockchain technology and cryptography, and the annual salary given is not less than 5 million yuan, and there is no ceiling
Song Mofei told reporters that in the actual development process, it is far from enough to simply master the use of some blockchain tools. Because there are still many problems in the efficiency and scalability of blockchain, developers need to improve the underlying platform of blockchain to meet the needs of practical application. The blockchain technology is a typical composite comprehensive discipline, which integrates cryptography, computer network and game theory. It is not easy to master and understand the underlying technology of blockchain overnightaccording to Shan Yi, chief data officer of liepin.com, the core of blockchain is the change of social relations and business model based on Internet distributed trust system, which is characterized by decentralization“ There are still many uncertainties in the future development of block chain. There are obvious bubbles at present, and many block chain projects are not reliable. He said

the demand for talents in Internet / game / software instry is large
according to the data released by liepin.com, in 2019, the demand for talents in Internet / game / software instry accounts for more than 77%, far ahead of other instries, followed by the financial instry, accounting for 6.5%
-- for more data, please refer to the analysis report on market prospect and investment strategic planning of China's blockchain instry issued by foresight Instry Research Institute
4. Blockchain as a technology, the essence of blockchain is a decentralized and distributed public ledger. Note that "public ledger" here is a logical concept. Each node maintains its own ledger data, and the so-called public ledger is to maintain consistency on each ledger, and the part that keeps consistency is the public ledger
generally speaking, blockchain companies need more technical talents, which is more concive to the development of the company. In addition, the long-term operation of the company is also a very important thing
from a small perspective, blockchain is still unfamiliar to the public, and more often, it needs more publicity and promotion.

5. Blockchain network has done a special article analysis, this instry is very promising, less talent, as long as in Colleges and universities to find.
6. If it's raw stone, the general quality (small particles and soft cracks) of Baijing is about 20 yuan per kilogram. If it's bracelet, I bought a better Baijing bracelet, 12mm, 20 yuan, which is less than 1 yuan per gram based on 25g. If it is more high-end varieties, such as garnet, amethyst, green ghost, the lowest quality of about 3 yuan a gram.
7. At present, it is in the early stage, and the application of blockchain technology is still vigorously supported by policies. The SMIC blockchain service platform launched by Changsha high tech Zone also solicits enterprises to go on the chain, which is a blockchain + public service mode.
8. Will not return to your principal, just like you bought life insurance, when the accident will pay you a certain loss, the principal will not return. Alipay safety insurance claims 100% compensation, 1 million upper limit!
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.

In recent years, blockchain and artificial intelligence have been very popular
first of all, blockchain is to establish a decentralized network. The so-called decentralization means that the network does not belong to you or me
it belongs to everyone
Artificial intelligence is a new technology science that researches and develops the theory, method, technology and application system for simulating, extending and expanding human intelligence. In other words, "machine self-learning"in this way, we can think about the combination of blockchain and artificial intelligence
first of all, we need to understand that blockchain can be divided into three stages
However, in the first three stages, there are some problems, such as the lack of decentralization, low scalability, the mismatching between the incentive of the blocker and the best profit of the whole network, and the network always running at the maximum capacity. Serious waste of resources and rece efficiencyso can we combine artificial intelligence with underlying public chain technology to solve these problems
The answer is yes! And there has been team research and development, and has made a certain progressVelas is a public chain that enhances its consensus algorithm through artificial intelligence (AI) optimized neural network, and carries out self-learning and self optimization. It is committed to improving the security, interoperability and high scalability of the transfer process and intelligent contract. Velas adopts the dpos consensus enhanced by AI, which completely realizes decentralization without recing the security and transaction speed. Not only that, AI chooses who to mortgage the token according to the needs of the blockchain; Velas only blocks when needed; Every 1 second to every 2 minutes; Scalability (up to 30000 TPS); Block procers are selected by artificial intuition
