1. Want to know what the development and applications of blockchain are?

The application scope of blockchain is spread across many industries

At present, the earliest One of its applications is Bitcoin, a blockchain underlying technology platform based on Bitcoin. As the name suggests, it is the Bitcoin network

Other blockchain underlying technologies now include IBM's Febric and Silver Chain's blockchain. The underlying technology platform, etc.

Up to now, the application of blockchain mainly has the following directions: 1

Financial industry

In the financial industry, areas Blockchain can be said to be the most popular FinTech (financial technology) in the world

There are also endless application cases in the financial industry, such as: Sunshine Insurance launched "Blockchain Aviation Accident Insurance" on July 29, 2016 "Card Bill"

Most aviation accident insurance will only issue insurance claims when an aircraft accident occurs. In most cases, fake insurance policies bought by customers are not easy to detect. Based on blockchain technology, the card bill can be traced from In the entire process from source to customer, all parties can not only check the authenticity of the card, but also facilitate subsequent processes, such as claims, etc.

At the same time, without middlemen, the unit price of insurance cards will be significantly reduced

p>

The economic benefits: You can buy one copy of this product for 60 yuan and can use it for 20 people. You can get up to 2 million yuan of aviation accident insurance each time, which is equivalent to getting 3 yuan for each trip. The guarantee of 2 million yuan

has greatly saved consumers’ expenditures and insurance companies’ costs

There is also the commercial bank mortgage released by Yinlian Technology in September 2016. This product is mainly used for the registration of real estate, vehicles and other assets to prevent repeated mortgages. It applies the consensus mechanism of the blockchain to improve the efficiency of inter-bank work

Financial Banks

< p>2. Blockchain drives the future: Can society really be programmed?

"Three o'clock" has been very popular recently, but what is even more popular is blockchain.

Since the "94 Incident", policies have become increasingly tight for the currency circle. In contrast, the "chain circle", which had rarely spoken out before, has become popular. Regardless of the media or the market, various voices discussing "blockchain" are emerging one after another in social circles large and small. Finally, during the Spring Festival this year, the popularity of "Sleepless at Three O'Clock Blockchain" brought this wave to its peak.

Finally, I would like to end with a quote from Zeng Ming (Chairman of the Academic Committee of Alibaba Group and Dean of Education of Hupan University), so that everyone can experience Teacher Zeng’s surging vision for the future:

p>

Today, what we are doing is to write trust consensus into the program before an economic ecology is born. What a ground-breaking thing this is! We are designing our own destiny! It's almost like we have a CRISP tool trying to encode genes. Just like the fundamental challenges that artificial intelligence encounters in cracking the human brain, the challenges of blockchain in designing the economic system that has evolved together with human society will also be fundamental and revolutionary. Because it directly faces human nature. Only by understanding Token at this level can we have enough awe and a true sense of mission for the historical opportunities and challenges we face.

3. What is the principle of blockchain technology development?

In a narrow sense, blockchain is a combination of data blocks that are connected sequentially in chronological order. A chained data structure and an untamperable and unforgeable distributed ledger guaranteed by Midanhuai wide cryptography.

Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, and uses cryptography to ensure data transmission and access. It is a new distributed infrastructure and computing method that uses smart contracts composed of automated script codes to program and operate data securely.

Working Principle

The blockchain system consists of data layer, network layer, consensus layer, incentive layer, contract layer and application layer. Among them, the data layer encapsulates the underlying data blocks and related data encryption and timestamps and other basic data and basic algorithms; the network layer includes distributed networking mechanisms, data dissemination mechanisms, data verification mechanisms, etc.; the consensus layer mainly encapsulates Various consensus algorithms of network nodes; the incentive layer integrates economic factors into the blockchain technology system, mainly including the issuance mechanism and distribution mechanism of economic incentives; the contract layer mainly encapsulates various scripts, algorithms and smart contracts, and is the area The basis of the programmable features of the blockchain; the application layer encapsulates various application scenarios and cases of the blockchain. In this model, the chain block structure based on timestamps, the consensus mechanism of distributed nodes, economic incentives based on consensus computing power, and flexible and programmable intelligent contract signing are the most representative innovations of blockchain technology. .

4. What is the chaos surrounding the blockchain craze?

According to reports, as blockchain has transformed from a cold and obscure professional term into a hotly debated "buzz" "At the forefront of the trend, many merchants with keen sense of smell are trying their best to seize the opportunity and use various fancy "hot spots" to take advantage of the opportunity to attract money. Behind the overwhelming pursuit of resources and capital from all parties, there may be a tangle of excitement and anxiety: seize the spotlight or pop the bubble?

Why is it so popular? It is reported that the "Traffic Ore Box" is an entry-level "mining artifact", which can be said to be mined using the sharing economy. It mainly collects and utilizes idle broadband resources and rewards users through the blockchain digital asset LLT of traffic ore. The digital asset LLT can be exchanged for shopping cards and recharged for electricity bills, phone bills, Internet bills, etc., to obtain certain real benefits.

Behind the heated discussion among the people, it is difficult to hide the entanglements and worries of all walks of life about the future fate of blockchain. “On the one hand, everyone realizes that blockchain has a promising future as a new technology and wants to seize the spotlight. But just because it is a new thing, at the same timeThere are also many uncertainties at this time, and there is a certain risk of bubbles. "Industry insiders admit that in the context of blockchain technology that is not yet mature, for some institutions that are "running into the game", how to cross the river by feeling the stones while guarding against "bad money driving out good money" is worthy of further consideration and consideration. Pay attention.

5. Floating losses exceeded 300 million yuan! Meitu’s big bet on cryptocurrencies “failed”

As the price of cryptocurrencies fell, Meitu, which had bought it at a high point, Meitu has tasted the "bitter pill." Meitu recently announced that it has confirmed impairment losses of approximately 311 million yuan (RMB, the same below) in its purchases of Ethereum and Bitcoin, resulting in a net loss of between 274.9 million yuan and 349.9 million yuan in the first half of the year. Yuan.

Analysts pointed out that Meitu’s allocation of Bitcoin and Ethereum cannot improve its technology and application level in the domestic blockchain field, and may hope to be boosted by the rise in cryptocurrency prices. Its performance. However, because Meitu purchased Bitcoin at a relatively high price, and the cryptocurrency market is extremely volatile, it is unclear whether it will bring benefits to Meitu in the future.

Recently, Meitu, a Hong Kong-listed company, issued inside information and profit warning announcements. As of June 30, 2022, Meitu may record a net loss of approximately 274.9 million yuan to 349.9 million yuan, compared with approximately 137.7 million yuan in the same period last year. The net loss of yuan increased by approximately 99.6% to 154.1%. The main reason for the expected increase in net loss is the impairment of purchased cryptocurrency.

On the evening of March 7, 2021, Meitu issued an announcement stating that, The Group purchased 15,000 units of Ethereum and 379.1214267 units of Bitcoin in open market transactions on March 5, 2021. The total consideration for these two cryptocurrencies was approximately US$22.1 million and US$17.9 million respectively, for a total of 40 million US dollars (approximately RMB 260 million). Subsequently, topics such as "Meitu purchased Bitcoin and Ethereum for US$40 million" and "Chairman of Meitu responded to buying cryptocurrency for US$260 million" became hot searches on Weibo.

More than ten days later, Meitu announced that its wholly-owned subsidiary Miracle Vision purchased a further 16,000 units of Ethereum for a total consideration of approximately US$28.4 million; and purchased 386.08 units of Bitcoin for a total consideration of approximately US$21.6 million. According to the announcement, the average transaction prices of Meitu’s purchases of Ethereum and Bitcoin were US$1,775 and US$55,900 respectively.

More than half a month later, Meitu announced its purchase again Cryptocurrency. Meitu has purchased a total of 31,000 units of Ethereum and approximately 940.89 units of Bitcoin, with corresponding total prices of US$50.5 million and US$49.5 million respectively, totaling US$100 million.

Buying coins is not yet available By one and a half years ago, the value of cryptocurrencies fell rapidly, and Bitcoin fell below the US$20,000 mark, which directly led to the decline of Meitu’s performance. Meitu is expected to soonIn the announced 2022 interim financial report, impairment losses of approximately US$18.5 million and US$27.1 million were confirmed for purchased Ethereum and purchased Bitcoin respectively, totaling approximately US$45.6 million, or approximately RMB 311 million.

Allocating cryptocurrency is a “big gamble” for Meitu to boost its performance and stock price. Meitu stated in the announcement that its investment in Ethereum was to prepare for entering the blockchain industry. Investing in Bitcoin is one of Meitu’s asset allocation strategies.

In fact, Meitu, whose transformation has not been smooth, has already tried to get involved in the currency circle. Cai Wensheng, chairman of Meitu, invested in cryptocurrency exchange OKEx in 2014. At the beginning of 2018, Cai Wensheng became the rotating group leader of the "Three O'clock Blockchain Group". Longling Investment, founded by Cai Wensheng, also has a stake in the cryptocurrency exchange FCoin.

Also in early 2018, Meitu launched a blockchain wallet product called Beautychain. Later, Beautychain’s token “BEC” was listed on OKEx, and Meitu was accused of Is the issuer of BEC tokens. In April of the same year, abnormal transactions occurred in BEC tokens that had been online for two months. A hacker used the batch transfer method of the contract to generate unlimited tokens, triggering a wave of selling and the currency price almost reaching zero. Meitu later stated that it “does not and will not issue any digital currency.”

Dong Sheng pointed out that according to Meitu’s statement in the announcement, investing in Bitcoin is only for one of the company’s asset allocation strategies, while investing in Ethereum is for Meitu to enter the blockchain industry. Preparations made. However, in the domestic market environment, allocating Bitcoin and Ethereum does not mean that Meitu is increasing investment in blockchain. The currency circle and the chain circle have always been distinct in China. Meitu's allocation of Bitcoin and Ethereum cannot improve its technology and application level in the domestic blockchain field.

Long-term losses have also caused Meitu’s stock price to collapse and its market value to plummet. Meitu’s stock price once exceeded HK$23 in March, the second year after its listing (2017), but then fell. From the second half of 2019 to 2020, it hovered around HK$1 for a long time. It only returned to HK$2 in February 2021, and has recently hovered around HK$1. As of the close of trading on July 5, Meitu closed at HK$0.93, which was the same as the closing price of the previous trading day. The stock price fell 10.58% the previous day.

6. What is the best investment direction in 2018

In the Spring Festival of 2018, the "3 o'clock sleepless block" Chain" has become popular in the circle of friends. This is the "world's first blockchain community" that gathers various VCs, blockchain entrepreneurs, Gao Xiaosong, Han Geng, Tong Liya and other artists. On February 26, "People's Daily" published a full page of articles related to blockchain. The full page reported three articles: "Three Questions about Blockchain", "Being a Leader in the Digital Economy" and "Seizing the Blockchain". This Opportunity" Three Questions about Blockchain, People's DailyMake a public call to seize the opportunity of blockchain. What is an opportunity? This is the best opportunity! If this is the chance God gives me in life, I will rush forward and seize it without hesitation.

Bin Elite Business School is a very loving and "clean" team, they are positive and look forward to growing with you

7. Following this trend, Tong Liya and Gao Xiaosong joined the "3 O'clock Sleepless" group, but Han Geng was kicked out

Recently, a "3 O'clock Sleepless Blockchain Group" (hereinafter referred to as the 3 O'clock Sleepless Group) is investing The circle is on fire!

According to China Entrepreneur Magazine, big names in the investment circle such as Sequoia Capital Shen Nanpeng, 360 Chairman Zhou Hongyi, angel investors Cai Wensheng, Xue Manzi, etc. are all in this group, and even Gao Xiaosong, Tong Liya , Lin Yoona, Han Geng and other stars.

This WeChat group, created on February 11, reached the upper limit of 500 members in less than a day. During the Spring Festival, it is said that the total amount of red envelopes in this group reached one million. However, this is not the main motivation for celebrities and big shots to join the group. It is even forbidden to publish information such as currency speculation and ICO in this group. People in the group mainly learn about the application prospects of blockchain technology.

I noticed that according to the definition of "China's Blockchain Technology and Application Development White Paper" issued by the Ministry of Industry and Information Technology, blockchain is a computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Innovative application models in the Internet era.

Blockchain technology is considered to be a disruptive innovation in computing models after mainframes, personal computers, and the Internet, and is likely to cause a new technological innovation and industrial change on a global scale.

Today, with the price of Bitcoin “cutting in half” from its peak, and the strict supervision of countries such as China, the craze for “virtual currency” has begun to dissipate. However, as the underlying technology, blockchain is expected to be widely used in finance, supply chain management, manufacturing, Internet of Things and other fields in the future.

The group once distributed over one million red envelopes in seven days

The "3 O'clock Sleepless Blockchain Group" was originally founded by Yuhong on February 11. Yuhong had previously He is the main person in charge of 360 Games and is now the founder of SEEU & QYGAME, which launched the large-scale online game "Basic World" based on blockchain.

Since it was three o'clock in the morning when the group was first established, it was named the 3 O'clock Sleepless Blockchain Group.

In this WeChat group, known as the No. 1 blockchain information group, there are Shen Nanpeng of Sequoia Capital and directors of 360Chairman Zhou Hongyi, angel investors Cai Wensheng, Xue Manzi, Fenbushi Capital partner Shen Bo, and even celebrities such as Gao Xiaosong, Tong Liya, Lin Yuner, and Han Geng.

Xue Manzi, Li Xiaolai, Chen Weixing, Shuai Chu and others are the earliest participants of the blockchain. Xue Manzi invested in Quantum Chain, Bytom Chain, and Mo Chain. Li Xiaolai is the first person in China to invest in Bitcoin and Ethereum. Chen Weixing also has his own fund and has invested in projects such as Huobi, Binance, and Tron. Shuai Chu is the founder of Quantum Chain.

Interestingly, the person who received the warmest welcome among those who joined the group was not the industry boss, but the film and television star Tong Liya. It is said that after Tong Liya was added to the group, there were hundreds of messages welcoming her to join. Tong Liya said that she is still a beginner in blockchain and hopes to learn more, and attached a big red envelope of 8,000 yuan.

Some inactive people in this group will be kicked out, such as Han Geng, No. 1 Matchmaker founder Mu Yan, Meitu CEO Wu Xinhong, etc. Those who remain in the group often engage in intense “mutual” discussions, and there are also some new members who are thirsty for knowledge and quickly absorb fresh knowledge about the blockchain.

On February 24, Chen Weixing in the group and Zhu Xiaohu, managing director of Jinshajiang Venture Capital, had a "mutual fight" around the blockchain.

The cause of the incident was that Zhu Xiaohu forwarded an article about blockchain in his circle of friends and said not to include him in various 3 o'clock groups. There are some outlets that he would rather miss and some money that he would rather not make. Otherwise, the late holiday will not be guaranteed.

This statement immediately aroused Chen Weixing's refutation. Chen Weixing asked, is the method of cutting leeks in equity investment more advanced than that in the currency circle? Is the bubble in the entire blockchain industry as high as the global stock market bubble? Zhu Xiaohu responded that ICO, a model that tests human nature, has never been successful.

Don’t talk about currency speculation, just talk about blockchain

Yuhong and the first industry tycoons Xue Manzi and Chen Weixing to join the group jointly set rules in the group: It is strictly prohibited to post news about currency speculation, ICO, etc. in the group. Therefore, the main topic of group chat is the application of blockchain technology.

Guo Hongcai is a well-known figure in the currency circle. He doesn’t know much about blockchain technology, but he became a rich man through currency speculation. He was kicked out of the group for the second time because he said in the group, "I'm here to make money anyway. Talking about technology is really meaningless... The biggest application of blockchain is currency speculation." After being kicked out, Guo Hongcai was unconvinced and sulked in another group, "They never talk about making money, they are too vain."

China has always been ahead of the curve in supervision.At the forefront of virtual currency speculation.

In September last year, China completely banned the domestic Bitcoin trading platform business. This regulation also has an impact on global Bitcoin transactions.

On February 5 this year, the People’s Daily published another article discussing “currency speculation” and believed that all countries should strengthen coordinated supervision to prevent systemic risks.

People's Daily stated that in recent times, various conferences and exchange activities with the themes of blockchain, digital assets, and virtual currencies have emerged one after another, and crazes such as "coin speculation" and "disguised ICO" have also emerged one after another. Some people join the "coin speculators", hoping to obtain huge returns through short-term speculation. Since blockchain and virtual currencies can transcend national boundaries, countries should strengthen coordinated supervision to prevent virtual currency transactions from causing systemic financial risks.

This is exactly what it is:

The virtual currency is booming,

and it is a series of sudden rises and sudden falls.

Beat the drum and spread the flowers, blow the big bubble,

There is an urgent need to regulate the cloud.

Blockchain has broad application prospects

According to the white paper of the Ministry of Industry and Information Technology, blockchain technology originated from a scholar with the pseudonym "Satoshi Nakamoto" published in 2008 The foundational paper "Bitcoin: A Peer-to-Peer Electronic Cash System".

In a narrow sense, blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable and Unforgeable distributed ledger.

Currently, blockchain technology is hailed by many large organizations as a major breakthrough technology that will completely change the way business and even organizations operate.

The widespread application of blockchain technology can enable "decentralization" to be realized at low cost.

When we send an email, what the other party receives is actually a copy of the email, which allows the information to be spread quickly. However, this approach cannot be replicated in applications in finance and other fields. For example, when you pay 100 yuan to the other party, you cannot copy and paste the 100 yuan currency in your hand to the other party.

Therefore, in today's society, transactions involving cash, securities, intellectual property rights, patents, carbon emission quotas, etc. must be solved with the help of a huge central institution (bank, third-party payment platform, etc.) Trust issues will increase transaction costs and slow down transactions. For example, we can send an email within a minute, but a transfer within the same city may take several days.time. Transferring funds from one country to another comes with high fees.

Canadian blockchain expert Don Tapscott believes that blockchain technology will change the world and make trust-building technology simple and easy to understand. He said that the popularity of blockchain technology means that we may no longer need a powerful central institution as a credit medium in the future. This is the next generation of the Internet, one that has the potential to transform our money, trade, government, and society.

8. How to develop blockchain

Share Zone View Network:

The application scope of blockchain technology is still very wide. Based on decentralization, With features such as trustlessness, collective maintenance, and reliable databases, its application in the financial industry is one step ahead.
Blockchain is the underlying technology of Bitcoin, and the application development of blockchain in digital currency is already mature.

Like the blockchain-based trading system development solution provided by Yingtang Zhongchuang, the developed software system has a high degree of security and transparency.

9. What are the basic concepts of blockchain programming and development technology

With the continuous development of the Internet, the development and application of blockchain technology has also been put on the agenda. Today Let’s take a java course to learn about the basic concepts that need to be mastered in blockchain programming and development technology.

1. Blockchain technology

Chain data structure, the head of each block stores the link to The hash value of the previous node is connected in sequence.

Based on the P2P network, the distributed node consensus algorithm maintains and updates data to ensure that the data is "non-tamperable".

Use cryptography principles to ensure the security of data transmission and access.

Automated scripts (smart contracts) to program and manipulate data.

Essentially it is a decentralized database, and what it ultimately wants to solve is the trust issue in Internet transmission.

2. Decentralization

The entire network is jointly participated and maintained by each node, and does not rely on central processing nodes , each node is a center.

Data storage and update are distributed and do not require intermediary or trust structure endorsement.

3. Private chain, public chain and alliance chain

Private chain:

p>

The qualifications for participating nodes are limited and controllable, and reading and writing are limited.

Weak centralization corrects the problem of trust among "teammates" (within the organization).

Public chain:

Open, anyone can read the data on the chain and participate in transactions.

Completely decentralized, the data on the chain cannot be tampered with by any person or institution.

Encourage participants to compete for accounting rights through the mechanism of rewarding positive and negative coins.

Solve the problem of "human beings" (all people) being untrustworthy.

Consortium chain:

It is jointly participated, maintained and managed by multiple institutions. The data on the chain is only allowed within the system. Institutions read, write, and trade.

Partially decentralized, each institution runs one or more nodes.

Solve the problem of "organizational" (inter-agency) distrust.

10. How do you view 2021 as the first year of the Metaverse, and how do you view the venture capital trend of the Metaverse

The reason why 2021 is the year of the Metaverse ’s first year, mainly due to three reasons: jumping ahead, technology, and monetization.
The metaverse is becoming the most popular topic nowadays. In many Internet circles or venture capital circles, if you don't talk about the metaverse, "surfing" for a hundred years will be in vain. The last time it caused such a buzz was the blockchain. If you think of the "Three O'Clock Blockchain" incident in 2018, it is not difficult to find that although the Metaverse is wrapped in a new skin, its popular logic is in the same vein as the blockchain. Too many gimmicks and not enough years is a wonder of the Internet. The popularity of the concept of the Metaverse means to a certain extent that the Internet industry has gradually entered the stage of stock competition, and capital has begun to look for the next "wind outlet." Companies represented by Facebook regard the Metaverse as the next stage of the Internet, hoping to gain new incremental development space in it.
The metaverse is called the next direction of the technological race. It is the direction of competition among major technology giants, and it is the integration of real life and virtuality. With the upgrade of network speed, it may change the way everyone lives and works, so it is highly valued from the enterprise to the national level.
The term Metaverse comes from the cyberpunk novel "Avalanche". In this novel, the author describes a virtual digital world parallel to the real world - the "Metaverse".
