B. Tencent has entered the blockchain, will this be Tencent’s next connector?

By 2015, a new technology has emerged that is very likely to become the next connector. That is blockchain.
As the underlying technology of Bitcoin, blockchain has broken through the financial industry. Especially with the emergence of alliance chain technology, blockchain has the potential to become the core connection technology of "Internet+". At the Guiyang Big Data Expo in May 2015, Ma Huateng emphasized that "Internet +" is also a connection ability. Then, Tencent will naturally not be absent from the blockchain, which is the connector in the "Internet +" era.
WeBank, initiated and established by Tencent, has already begun to practice in exploring blockchain.
In May 2016, WeBank participated in launching the Financial Blockchain Cooperation Alliance (hereinafter referred to as: Golden Chain Alliance) in Shenzhen, China. In June, it launched an alliance chain cloud service based on Tencent Cloud.At the end of September, during the Shanghai Blockchain International Week, a cooperation agreement was reached with Wanxiang Group.

This series of signals shows that Tencent has entered the blockchain competition and is trying to build the blockchain into the next connector. (NetEase Finance)

Of course, other application scenarios of blockchain are also everywhere, such as the digital currency crowdfunding launched by Biying China; the asset custody system developed by China Post based on blockchain technology .

C. Hurun released the "Global Unicorn List" for the first time, 11 blockchain companies were selected

Hurun released the "2019 Hurun Global Unicorn List" for the first time, 11 Blockchain companies selected!

"Blockchain can be said to be the industry that creates wealth the fastest."

"Hurun Report, chairman and chief researcher of Hurun Report, said that as long as blockchain When emerging industries become bigger in China, they will lead the world."

This is the first time that Hurun Research Institute has released a global unicorn list after releasing China's Unicorn Quarterly Index six times.

On October 20, at the World Internet Conference held in Wuzhen, Zhejiang, Hurun Report, chairman and chief researcher of Hurun Report, released the "2019 Hurun Global Unicorn List" on the spot. List2019), this is the first time Hurun Research Institute has released a global unicorn list. The deadline for calculating the valuation of this list is June 30, 2019.

Hurun said that China's wealth creation in the past 20 years was the fastest in the world. According to the "Global Unicorn List", China has 206 companies on the list, surpassing the United States (203) to rank first in the world. Ant Financial becomes the world’s largest unicorn. The "Global Unicorn List" is a global ranking of technology start-ups with a valuation of more than US$1 billion. The companies on the list have been established for no more than 10 years, have received private equity investment and have not been listed.

It is worth noting that compared with traditional industries, blockchain can be said to be the industry that creates wealth the fastest. According to the list, the number of unicorns in the blockchain industry is 11.

11 blockchain companies were selected

According to the first "Hurun Global Unicorn List 2019" released by Hurun Research Institute, there are a total of 11 blockchain companies in the world. 494 unicorn companies are on the list, and the number of unicorns in the blockchain industry is 11, namely Bitmain (valued at RMB 80 billion), Coinbase (valued at RMB 55 billion), and Ripple (valued at RMB 55 billion) 35 billion yuan), Canaan (valued at 20 billion yuan), Circle Internet Financial (valued at 20 billion yuan), Binance (valued at 15 billion yuan), Block.One (valued at 15 billion yuan) ), Dfinity (valued at RMB 15 billion), Yibang International (valued at RMB 10 billion), BitFury (valued at RMB 7 billion), Liquid Global (valued at RMB 7 billion).

It is worth noting that the three major mining machine giants Bitmain, Canaan, and Yibang International are all on the list. In terms of exchanges, they are Binance, Coinbase and Liquid Global.

In this regard, Hurun Report chairman and chief researcher Hurun said that as long as emerging industries such as blockchain become bigger in China, they can lead the world. "Surprisingly, the United States is not the country with the most unicorn companies in the world. The number of unicorn companies in China ranks ahead of the United States. The opportunities brought by the new economy are global, as long as you develop this industry in China Big, you will suddenly lead the world, such as e-commerce, cloud computing, artificial intelligence, blockchain and other emerging industries."

Ketuan Zhan became the "richest man in China's blockchain" in 2019

According to previous reports from Mars Finance, on October 10, 2019, Hurun Research Institute and LEXUS jointly released the "2019LEXUS.Hurun China Rich List" (2019LEXUS.Hurun China Rich List). This is the Hurun Research Institute The "Hurun Rich List" has been released for the 21st consecutive time since 1999. According to the list, Jack Ma became China's richest man for the third time with a wealth of 275 billion. Ma Huateng's wealth increased by 20 billion, returning to second place with 260 billion. Real estate developer Xu Jiayin's wealth shrank by 40 billion, falling to third place with 210 billion. It is worth noting that Ketuan Zhan, the founder of Bitmain, ranked 100th, has become the richest man in China’s blockchain field with a net worth of 30 billion.

Compared with traditional industries, blockchain can be regarded as the fastest industry to create wealth. On November 13 last year, Hurun Research Institute also released the "Hurun Blockchain Rich List 2018" for the first time, with 14 people on the list. Although there is still no killer application in the blockchain field this year, there are still 14 people on this year’s list.

According to the list, the people on the list in the blockchain field are mainly from exchanges and mining. Among them, Bitmain founder Micree Zhan topped the list with a wealth of 30 billion, Binance founder Changpeng Zhao ranked second with 18 billion, and Bitmain co-founder Wu Jihan ranked third with 17 billion.

There are three people on the list in the exchange track, namely Binance founder Changpeng Zhao with a net worth of 18 billion, ranking 195th; OKCoin founder Xu Mingxing with a net worth of 10 billion, ranking 398th ; Huobi founder Li Lin ranks 531st with a net worth of 7.5 billion.

Nine people from the mining industry are on the list, including five from Bitmain. In addition to Ketuan Zhan, Wu Jihan (worth 17 billion), Zhao Zhaofeng (with a net worth of 5.1 billion), Hu Yishuo (with a net worth of 3.4 billion), and Ge Yuesheng (with a net worth of 3.5 billion) ranked 214th, 816th, 1204th, and 1166th respectively on the list, which are worth mentioning. Yes, as a post-90s shareholder of Bitmain, Ge Yuesheng became the youngest person on the list in the team.

In terms of investment, Shen Bo, founder of Fenbushi Capital, is on the list with a net worth of 8 billion yuan, ranking 502nd. Wang Mingliu, founder of Maoqiu Technology, a blockchain computing service company, is a new member on the list, with 60 The net worth is ranked 684th. Finally, it is worth noting that Li Xiaolai, who was on the list last year, is not on the list this year.

Blockchain has huge potential, and empowering the real economy is the key

As can be seen from the list, exchanges and mining have the clearest and most profitable business models in the blockchain ecosystem. The strongest mode. Blockchain is not only a technology, but also a new track for global competition. From Bitcoin to Facebook Libra to central bank digital currencies, they are all innovative applications based on blockchain. However, the rapid development of the blockchain industry has not only brought innovation and wealth, but also bubbles and speculation.

The ICO bubble burst in the second half of 2018, and the total market value of cryptocurrency fell to US$700 billion, a drop of 85% from the peak in January 2018. The return of air coins to zero reflects the fact that many blockchain-based Commercial applications lack actual value and asset support, and empowering the real economy has become a basic consensus in the development of blockchain technology. As blockchain technology welcomes the 3.0 era, the industry's attention is gradually sinking. It should also pay more attention to the application and implementation of related technologies and deeply tap its growth potential, so as to truly seize the dividends of this era.

D. What companies are currently exploring blockchain technology

Zhuo Qiyun Chain, this company is Yimi The blockchain technology company has a professional blockchain team and has developed many blockchain application projects. You can go and learn about them together. I hope my answer can help you.

E. What are the blockchain companies?

As follows:

At present, almost all Internet companies have started to develop blockchain. Most traditional financial companies are involved. There are serious pure blockchain companies that do some technology research and development, including Yunxiang, Qulian, and Taiyi; there are also companies that do public chain main chains, such as Xunlei, Xiaoyi, Byuan, etc.

There are also many companies that are actually working on blockchain technology, such as Qulian Technology, Wanxiang Blockchain, Energy Chain Group, Complex Beauty Technology, Galaxy Blockchain, Zhigui Technology, and Medical Chain The group is relatively well-known in the industry andSome companies with good technology. Internet giants basically have blockchain sections.

More than 10,000 new blockchain companies will be added in 2020

Despite the COVID-19 pandemic, China’s blockchain industry is still growing significantly. As of July 2020, more than 10,000 new blockchain companies have been established in China. The number of new companies in 2020 exceeded the 18,500 in 2019.

The continuous influx of new blockchain companies has laid the foundation for the development of my country's blockchain industry. However, due to the rapid development of the blockchain industry, there is a shortage of professional talents to match it, and most employers will face the problem of recruiting people.

F. Alibaba and Tencent have entered the game, what is the magic of NFT?

Overnight, NFT has become a hot topic.

This concept, which seems to be only popular in geek circles, is now extremely popular "outside the circle". Starting in 2020, people from all walks of life, from Elon Musk to Yao Ming, from Coca-Cola to Disney and Marvel, to LV, GUCCI, eBay, and Facebook, have begun to play with NFT.

Sky-high auctions are an important driver of NFT’s emergence in the industry - a set of works by digital visual artist Beeple, "Everydays: The First 5000 Days", was auctioned for a sky-high price of US$69.35 million at Christie's in the form of NFT. ; The "world's first tweet" consisting of only five words posted by the CEO of Twitter was auctioned for US$2.9 million. Currently, there are four crypto artists in the world who are worth hundreds of millions because their works are popular in the NFT field.

All kinds of strange things have been minted into NFTs, such as Steve Jobs’ handwritten “job application”, NBA highlights, sneakers, WeChat/QQ avatars, virtual stones, Buddhist amulets, real estate, and World Wide Web source code , Nobel Prize papers, Time Magazine covers, etc.

In the scene where “everything can be NFT”, what exactly is NFT?

NFT is a Non-Fungible Token, and its "non-fungible" means that each NFT is unique and indivisible. This means that when a work is minted into an NFT, it becomes a unique digital asset on the blockchain.

Technological revolution, copyright protection variables, speculative bubbles, the prelude to the metaverse... different people have very different meanings in NFT. As NFT is making rapid progress in overseas markets, more and more domestic players are embracing this new thing. After the rise of the art field, domestic Internet giants have also sought to enter NFT. What changes will it bring about, and what do the major manufacturers intend to do?

Judging from the most practical results of technology implementation, entertainment, The art industry is currently the most enthusiastic embracer of NFT.

NFT provides new ideas for solving copyright issues. When a work is cast into an NFT and put on the chain, the work is given a unique code that cannot be tampered with to ensure its uniqueness and authenticity. In this way, no matter how many times the work is copied or distributed, the original author remains the sole owner of the work.

Not only that, compared to traditional art trading forms, when NFT circulates, every transfer of its ownership means that the creator can profit from it. Take the trading platform Super Rare as an example. When conducting a first-hand transaction, the artist will receive 85% of the income, and the platform will receive 15%; when performing a second transaction, the seller will receive 90%, and the artist will receive 10%. In the traditional trading method, even if the original work is sold to sky-high prices in multiple circulations, it is difficult for the artist to profit from it again.

The potential for profit has attracted speculators. Coupled with the existing high-return cases of NFT, many players hope that the value of the NFT they bought will increase overnight.

Data from nonfungible.com, a website that tracks NFT market activity, shows that after Beeple’s work was sold at Christie’s this year for more than $60 million, the NFT market transaction volume that week reached $100 million for the first time. Although the subsequent decline in the cryptocurrency market had a certain impact on NFT transaction volume, in early May, the NFT market's transaction volume soared to nearly $200 million that week.

With the enthusiastic support of artists, geeks, investors and other parties, a mature NFT trading mechanism has gradually formed overseas - after the creator releases the NFT for the first time, other Buyers can continue to make secondary transfers and purchases on the NFT trading platform.

The process of an NFT being sold for the first time occurs in the primary market. There are many popular NFT projects in overseas markets. Data from nonfungible.com shows that in the second quarter of 2021, there were three NFT projects with sales of more than 10 million US dollars in the primary market, and there are currently four projects in the market worth With more than 10 million, MeeBits, the most valuable NFT project among them, is worth US$90.76 million. In addition, NBA Top Shot, which sells highlights of NBA stars, and CryptoPunks, which sells pixel avatars, are also very popular NFT projects.

The circulation process after issuance is the secondary market transaction. In addition to OpenSea, the world's largest digital collection trading platform, trading platforms Nifty Gateway, MakersPlace, Rarible, etc. are also very active. Most NFT trading platforms are based on the public chain "Ethereum", but due to Ethereum's low throughput, high transaction fees, and generalThe road is crowded, and some platforms will also choose to be based on new public chains such as Flow and GSC. In addition, large NFT trading platforms such as OpenSea and Rarible also have the "issuance" function of the primary market.

Compared with the popularity overseas, the development of NFT in China is a little late, but now more and more domestic players are involved in NFT.

The popularity of NFT in China also starts from art. Chinese crypto artist Song Ting is the 2020 Chinese NFT crypto art auction record holder. Since March this year, musicians Gao Jiafeng and Aduo have released their own NFT digital music works and been bought at high prices.

However, what is more conspicuous and influential is the entry of enterprises and institutions. At present, one of the institutions most actively embracing NFT is the music copyright agency:

In May this year , Alibaba Auction launched a special NFT digital art session, and then Alipay jointly launched 4 NFT payment code skins with the Dunhuang Fine Arts Institute and the domestic animation "Assassin Wu Liuqi" in June; in July, the IP of NetEase's game "Eternal Tribulation" was also authorized for distribution NFT; Tencent launched the NFT trading software Huanhe APP in August, with the first limited sale of 300 "Audio "Thirteen Invitations" Digital Art Collection NFT". Tencent Music (TME) also announced the first batch of limited edition "TME Digital Collection" "It will be released on QQ Music one after another.

However, unlike the public chains chosen by most overseas NFT trading platforms, when Tencent and Alibaba entered the NFT field, they were based on the alliance chains of Zhixin Chain and Ant Chain built by their own companies respectively. Compared with public chains, alliance chain participants are controllable and have stronger privacy protection capabilities. In addition, NFTs launched by Tencent, Alibaba, NetEase, etc. cannot be traded for secondary transactions.

For example, after users purchase the "Audio "Thirteen Invitations" Digital Art Collection NFT", they can only view and collect it. The platform does not provide opportunities for secondary transactions, and currently users cannot The platform launches its own NFT works. Similarly, users can only view and collect Alipay payment code skins, and cannot transfer them to gifts or make secondary transactions.

In the context of the immature development of NFT in China, the caution of major manufacturers is obviously to prevent the testing of waters from turning into a hype craze for speculators. However, the signals revealed by the successive entry of entertainment industry and technology companies are equally obvious: NFT is an existence that cannot be ignored.

People's attitudes towards NFT are divided into two extremes: supporters believe that NFT will not only affect copyright protection methods, but also from a longer-term perspective, NFT will make the concept of the "metaverse" a reality; but opponents But I feel that NFT is just a new way of speculation.

Both are not unreasonable. The impact of NFT itself is multiple.

The metaverse refers to a virtual world that is born out of the real world, parallel to the real world, affects each other, and is always online. NFT can serve as an important infrastructure of the Metaverse, capable of mapping virtual items and becoming the main carrier of native assets in the Metaverse.

In March of this year, because the game company Roblox wrote in its IPO prospectus that "Metaverse (Metaverse) is being realized", in the following six months, the game industry ushered in the Metaverse boom. According to the Financial Associated Press, in the first half of 2021, NFT blockchain games have raised US$1.4 billion in financing, and the number of daily active users of the NFT blockchain game Axie Infinity is as high as 250,000.

Some participants who have nothing to do with blockchain are also getting involved in the NFT game. On August 4, French fashion giant Louis Vuitton announced the launch of its own NFT mobile game; in July , Coca-Cola released an NFT virtual device that can be worn on the decentralized virtual reality platform Decentraland.

William Quigley, the former co-founder of USDT issuer Tether, said in an interview in July: “NFTs will coexist alongside movies, music and video games as a unique form of entertainment. All All consumer goods that cannot be eaten will become NFT.

Supporters regard NFT as part of their faith, but there are also many people who are cautious or even negative about the development of NFT.

Speculation is the most obvious chaos in the NFT craze. The higher and higher the price of NFT, the more and more outsiders are jealous, and it continues to attract new players to enter the market eagerly. Many voices compare NFT with the "" At that time, exchanges at the top of the food chain did not strictly review air coins, resulting in a large number of air coins. The exchanges were therefore questioned for wantonly "harvesting" project parties and investors.
< br /> Will NFT follow the footsteps of air coins? There is no answer yet. Although many celebrities support NFT, the voice questioning NFT is hard to ignore.

Fred Ehrsam, founder of Coinbase He said earlier: “90% of NFTs produced may lose value in the next 3 to 5 years and become almost worthless. This is the same situation as the early Internet companies in the late 1990s. "The artist Beeple, whose works were auctioned for high prices earlier, also said in an interview with CNN's "First Move" that NFT was sold for $69.35 million.

Litecoin founder Charlie Lee also believes that only a fewNFTs are extremely valuable, such as works created by well-known artists like Picasso, but "since the cost of creating NFTs is almost zero, if artists flock to this field in order to make a profit, the market will be driven by this craze." submerged, supply will overwhelm demand, and prices will eventually collapse.”

Regulation is another pressure that NFTs may face. The cautious attitude of major domestic manufacturers in promoting NFT reflects their emphasis on compliance. Alibaba and Tencent have repeatedly emphasized the scope and boundaries of their deployment in the NFT field.

In response to the misunderstanding of whether NFT is equivalent to issuing tokens, Ant Chain has made it clear: NFT is not a virtual currency. "NFT is an effective and reliable technical means to solve the problem of confirming the rights of digital artworks. It is unique and indivisible, does not have the characteristics of equivalent exchange, and is essentially different from virtual currencies such as Bitcoin."

In an online roundtable forum held by Tencent Research Institute, Qin Qing, director of blockchain products at Tencent Cloud, also said that issuance of NFT on the alliance chain can truly remove the attributes of currency. "We infer that the alliance NFTs issued on the chain can be issued in compliance with regulations."

NFTs are complex. Although they are a better way to protect copyrights, they also have potential hype attributes. The road to development in China It is also inevitable that China will face supervision. How can the development of NFT leverage its strengths and avoid its weaknesses? All Chinese participants need to explore the appropriate development path for NFT.

G. What are the leading blockchain listed companies?

As of August 11, 2021, there are a total of 251 blockchain concept stocks listed on the Shanghai and Shenzhen stock exchanges.

The above are my statistics of leading listed companies in the blockchain industry. I apologize for the inaccurate statistics and hope to communicate with you more. , thank you all for your attention!

H. Which companies are relatively mature in developing blockchain technology

Shandong Bianke Information Technology Co., Ltd. is a software development company with excellent technology.

[Blockchain Exchange]

Blockchain technology application research and development, exchange wallet system app development Blockchain technology is actually a new type of Internet. Why is it said to be a subversion of the Internet? Because the Internet solves the problem of information transmission, and the blockchain solves the problem of value transmission. Yuanzhongrui Blockchain System Development Blockchain has many value transfers, such as distributed ledgers, decentralized trust, smart contracts, etc. So what kind of society will it build in the future?

The answer is: a distributed business and self-disciplined society. The first characteristic of blockchain is decentralization; no third-party intervention is required to realize person-to-person, point-to-point transactions and interactions.

Second, the information cannot be tampered with; once the data information is written into the block, it cannot be changed or revoked.

Third, openness and transparency; very short timeWithin, the block information will be copied to all blocks in the network to achieve data synchronization across the entire network, and each node can trace back all past transaction information of both parties.

Fourth, collective maintenance; in the entire blockchain network, all roles jointly maintain the reliability and security of the entire blockchain information.

Fifth, reliable database; only by mastering 51% of the nodes in the entire system can the blockchain information be tampered with. This is obviously impossible because there are many participants in the entire system and so many nodes are mastered. The cost is extremely high and it is impossible to achieve.

The characteristics of blockchain bring great opportunities to the financial industry. Using it to transform internal application scenarios in the industry can bring three main benefits:

< P>1) Reduce costs: Communication costs: Centralized trading markets generally require the participation and coordination of multiple parties such as central settlement systems, securities companies, exchanges, and banks. The coordination costs are very high. Through the signature encryption next to the blockchain source, etc. Technology allows information to be shared and reduces coordination costs; operating costs: reducing labor and paper vouchers, improving automation through smart contracts, and centralized coordination also bring very high operating costs.

2) Improve efficiency: The settlement cycle is very fast. When the financial transactions realized through blockchain technology are confirmed, it is actually a settlement process that combines clearing, settlement and auditing. The openness, transparency and non-tamperability of the blockchain can save traces of operations, allow supervision records and audit traces to be retained, and facilitate supervision and auditing.

3) Risk reduction: Transaction confirmation on the chain completes clearing and calculation, greatly reducing transaction risks. Blockchain technology application research and development, exchange wallet system app development
