③ Blockchain can be defined

On March 12, 2018, the second session was co-sponsored by Hangzhou Science and Technology Commission, Hangzhou Financial Affairs Office, Xiaoshan District People’s Government, and Herangna Hangzhou Daily Newspaper Group, and hosted by Hangzhou Venture Capital Association and Hangzhou Bank The Growth of All Things Conference was held in the press conference hall of Hangzhou International Expo Center. Babbitt and Bytom founder Chang Chai gave a keynote speech on "The future can be predicted and blockchain can be defined."
The following is the content of the speech:
Good morning everyone, I am very happy to be invited to do such a sharing. The theme I shared is "The future can be predicted and blockchain can be defined."
I used to be a science fiction writer and wrote some science fiction novels in college. At that time, science fiction was still a very niche group and very few people read science fiction novels. Later, I had a post that is now very popular. In 2011, a college student asked on Zhihu: If you have 6,000 yuan for investment and financial management, what advice do you have? The advice I gave him at that time was to buy Bitcoin. . Now it seems that this is a piece of advice worth 20 million. Of course, it is a sad story because the subject did not buy Bitcoin in the end. It is also a sad story for me, because many people in the novel I wrote I haven’t read it, but this advice is often mentioned. In recent years, people have been sending me private messages asking me which coins to buy. However, I am not an expert in investment and financial management. Our company is engaged in blockchain.
Babit established the website in 2011 and established the company in 2014, so we may be the first batch of blockchain companies in China. On what basis do we judge that blockchain technology may be popularized or survive in the future?
This would like to mention a science fiction novel I once wrote in college called "The Art of Slaying Dragons". This computer-themed novel was written in 2007. It tells the story of hackers who can use huge amounts of computing resources on the Internet in the cloud era to complete some very grand scientific computing projects. After this novel was published at the time, it was criticized by many readers. They think this novel seems unreal and doubt that hackers' abilities are beyond ordinary people's imagination.
But now it seems that this novel is not an exaggeration at all. Why? Because in the cloud era, the abilities between people will be disproportionately amplified. In reality, the abilities between people may be a kind of The normal distribution is just like a person's height and weight, but on the Internet, people's ability and influence will be disproportionately amplified. It is a combination of the Matthew effect + the long tail effect.
The core ideas of this novel are two points. The first point is that cloud computing will amplify people's abilities, and the improvement of computing power will amplify people's abilities. The second point is that computing is power. So when Bitcoin is like thisAfter new things come out, it seems like the world written in my novel is becoming reality. When Bitcoin was introduced to China from 2008 to 2010, many people had already heard of Bitcoin, but did not pay attention to it. In fact, to understand a thing like blockchain, some knowledge background is needed.
In addition, I would like to introduce a book, which is "Out of Control" written by Kevin Kelly. This book was written in the 1990s, but this book is very prophetic. One of its chapters introduces the cryptocurrency Pioneers, but these pioneers later became martyrs, what was the reason for their failure? In fact, blockchain needs to be based on three core technologies, and these three technologies are gradually maturing. The first technology is asymmetric encryption. In 1985, elliptic curve function encryption was already very mature, but unfortunately it was implemented in a centralized way. What are the risks of centralization? That is, when issuance If the currency company collapses or the founder is arrested, or the central server is attacked, it will cause the system to collapse, so it failed later. In 2000, someone began to introduce peer-to-peer technology into cryptocurrency for the first time, taking the lead in realizing distributed cryptocurrency. However, it also failed later. The reason is very simple, that is, there is no way to find a way to solve double payment (the same money is used). twice). It was not until 1997 that Adam Baker proposed proof of work. In 2004, Halfini expanded this technology into a reusable proof of work, so the 2008 Bitcoin white paper was successfully published.
And the carefully designed technical solutions in Bitcoin later seemed to be very advanced. For example, in 2014, Snowden revealed that elliptic curve function encryption is unsafe because the US National Security Agency has set up a backdoor in this encryption standard, giving the NSA an unknown method to weaken this curve. , at that time many people exclaimed that Bitcoin was dead and that the system might collapse, but later Satoshi Nakamoto did not use the encryption standard promulgated by the National Security Agency, but used a very rare curve.
To give another example, after hashing twice, a quantum computer cannot threaten the Bitcoin address and cannot decipher the Bitcoin private key from the address. What’s more interesting is that Satoshi Nakamoto also adopted a weird transaction method called a change mechanism. The change mechanism is that the remaining balance of each transaction is transferred to a new address. Now it seems that this is actually for the purpose of Prevent quantum computers, because the public key of a Bitcoin transaction will only be exposed on the blockchain during the transaction. You only need to transfer the remaining money to a new address during each transaction. In fact, you The public key will not be exposed on the blockchain.
So judging from so many details, it can be said that Satoshi Nakamoto is a bit like a person who is extremely careful, so many people think that he is not a person, but an organization.
I just mentioned why the proof-of-work mechanism was introduced to the blockchain and Bitcoin, and this cryptocurrency was successful? Because the proof-of-work mechanism is actually hash calculation, why is calculation so important to the blockchain?Want? I can give a very easy-to-understand proof through such a table.
This table shows that the real world and the digital world are actually in a mirror relationship. The real world can also be called the atomic world. In the real world, things are randomly distributed and random. In the digital world, everything is generally Pseudo-random. In the real world, there are no two identical leaves. Everything on the Internet can be copied. In the real world, it is a normal distribution. In the digital world, it is a power law distribution. It is the Matthew effect + long tail effect. . In the real world, things are competitive resources, which are exclusive resources. For example, if I own a microphone or a glass of water, others cannot own it. All resources in the digital world are non-competitive resources. For example, I transfer a document and article to another person, but in fact this document cannot be transferred like a book in reality, because this document may be saved infinitely in my computer or other storage media. A copy, so based on such a mirror relationship, we can ask the question, why is it so difficult to copy exactly the same thing in the real world? This question can be turned into whether you can create a perfect crystal in reality, you can create A perfect crystal can actually copy exactly the same thing, but the third law of thermodynamics tells us that if you want to create a perfect crystal, you need absolute zero, and you have to invest a huge amount of energy. In turn, through this symmetrical thinking, we can This raises the question that in the digital world, that is, on the Internet, it is very difficult to prevent something from being copied and to achieve such competitive resources. To achieve such a competitive resource, a huge amount of personnel consumption is required, which is computing. The more computing power invested, the higher the barrier against double spending, which is why computing matters.
So since the real world and the digital world have such a mirroring relationship, the blockchain can actually be understood as the reverse machine of the printing press. I like to use such a very vivid metaphor to define the blockchain as the printing press. Reverse process.
Why is the printing press so great? In fact, before the birth of the printing press, human knowledge and information were competitive resources. Whether it was the Bible or martial arts secrets, they were all competitive resources. But after the birth of the printing press, this knowledge and Information has become a non-competitive resource that can be copied on a large scale, or the marginal cost of copying is almost equal to 0, so there is the subsequent information revolution. With the Internet, the Internet is actually an enhanced version of the printing press. But the problem with the Internet is that it is difficult to transfer competitive resources in the digital world. This is also the reason why some cryptocurrency pioneers failed in the 1990s. Blockchain solves this problem. It is the first to realize competitive resources on the Internet. The first competitive resource is of course Bitcoin, which is the first domino to be erected. After the first card falls, we can imagine that the second and third cards will fall as long as they have value attributes. They are all very suitable for using blockchain for registration and circulation, because the InternetThe Internet is suitable for things with information attributes, so we say that the Internet is an information transmission protocol, and the blockchain is a value transmission protocol. All resources with value attributes are actually very suitable to be combined with the blockchain.
So I don’t think the blockchain will replace the Internet. The blockchain itself is a parallel world of the Internet. It is to do some things that the Internet cannot do, so it may propose many business models. In my opinion, it is not It is unrealistic. For example, it combines things with information attributes and business scenarios with blockchain. In fact, I think it is not that appropriate, because scenarios with information attributes are suitable for the Internet, and only scenarios with value attributes are suitable for "blockchain." +".
Let’s further deepen the mirroring relationship between the Internet and blockchain. The carrier of the Internet is often software, and the carrier of blockchain is generally protocols. Software needs to apply for patents to establish its own patent barriers. On the contrary, with blockchain, most blockchain projects are open source, and you are very welcome to copy it. The code does not need to establish such patent barriers or moats. The main body of software development is usually a company, and the main body of blockchain development is often a community or foundation, which is a very loose organizational form. Software requires constant iterative upgrades, but iterative upgrades of protocols are very difficult, so they are generally very stable, because protocol upgrades require the approval of the consensus of the entire network, which is of course very, very difficult. That’s why there are so many Bitcoins. The software can be maintained and updated, and the protocol is that it cannot be shut down after it is started, and it runs 24 hours a day. Based on this kind of thinking, we can solve many doubts in our hearts. For example, in 10 years ago, many experts or big names in the investment community believed that although Bitcoin was a pioneer, it would not necessarily have the last laugh. How to prevent being defeated by latecomers? This is a typical Internet thinking. Internet thinking regards Bitcoin as a software. Through technological upgrades, latecomers may catch up, just like the browsers in the 1990s. Later, the early browsers were defeated by the newcomers. But in fact, Bitcoin cannot be regarded as a kind of software, but a protocol. The method of implementing this kind of blockchain is already a minimum feasible solution, and there is not much room for optimization.
Many people understand blockchain as the fifth paradigm revolution, because it is based on the summary of technological updates in the past few decades, which means that such a paradigm revolution, a leap-forward revolution, will be completed approximately every two years. The 1970s were mainframes, the 1980s were PCs, the 1990s were the Internet, the 2000s were the mobile Internet, and the blockchain was born in the 10s. The trend behind this is actually a trend of decentralization. Mainframes are in scientific research institutes or military institutions. PCs have entered families. The Internet has entered tens of millions of people. Mobile Internet has pervaded the world. In all aspects of life, blockchain has become more decentralized, and there is no longer even a central server. There is another detail here, that is, the time of the blockchain is calculated from January 1, 1970. Why does it have such a feature? In fact, it is because many programming languages ​​​​are derived from Linux.System, Linux comes from the mainframe, so it has the imprint of this era invisibly.
In fact, there is a deeper evolutionary law behind it, such as the three stages of asset evolution. The evolution of assets can be divided into three stages. The first stage is the confirmation of asset rights, which is the equityization of assets and the confirmation of asset rights. It can then be transferred as a whole, so it's kind of like the solid stage of the asset. The second stage is asset securitization. After securitization, the assets can be divided and transferred, and their liquidity is obviously stronger. It is a bit like the liquid stage of assets. The liquid stage also has its limitations. For example, the business requires a container. , this container is the platform for assets, and assets still cannot flow across platforms. Only after the assets are blockchainized, that is, after the assets are put on the chain, will they truly enter a gas phase, because everyone can manage assets through their own private keys, whether it is Equity, income rights, debts, intellectual property rights, etc., as long as they are assets with this value attribute, they are suitable for registration and circulation using the blockchain, so they are no longer limited by the platform, because everyone can complete it through their own wallet. The process of asset transfer does not require a centralized authority or a centralized trading place. More broadly, many people have summarized the stages of blockchain evolution. The first stage was in 2009 with Bitcoin as the Representing the stage of cryptocurrency to solve value transfer matters, it can be understood as the 1.0 of blockchain. In 2017, the era of issuing virtual assets through smart contracts emerged, represented by Ethereum, which can be understood as the 2.0 of blockchain. We believe that we will enter the third stage in 2020, using smart contracts to issue physical assets or help real assets to be put on the chain. The blockchain will eventually move away from the virtual to the real and serve the real economy. So Babbitt is doing the third stage, which is our prediction of the future development trend of the blockchain.

④ The top 20 blockchain projects were unveiled at the Hi-Tech Fair and achieved remarkable results in technological and industrial innovation and development

From November 11th to 15th, the 22nd China International Hi-Tech Fair The Technology Achievements Trade Fair (hereinafter referred to as the "High-tech Fair") was officially held at the Shenzhen Convention and Exhibition Center, with a total exhibition area of ​​more than 140,000 square meters, more than 3,300 domestic and foreign exhibitors, nearly 10,000 projects participating in the exhibition, and more than 140 various activities.

The top 20 blockchain companies made a collective appearance at the Hi-Tech Fair

On the morning of the 11th, the exhibition hall was crowded with visitors and professionals. Yang Jianjun, deputy director of the Electronic Information Department of the Ministry of Industry and Information Technology, and Fan Shujian, deputy director of the Science and Technology Department, visited the booths of the top 20 blockchain projects during the tour and listened to the staff introductions to learn more about the latest progress of blockchain technology and its application in the industry. The actual situation of landing.

On October 24 last year, the country regarded blockchain as "an important breakthrough for independent innovation of core technologies." Over the past year, blockchain technology and industry development have also opened a new era, with demonstration applications emerging one after another. middleYu Jianing, rotating chairman of the Blockchain Professional Committee of the China Communications Industry Association and president of Huobi University, said that the top 20 blockchains displayed this time were selected by multiple recommendation institutions based on industry development and after several discussions and surveys. Representative blockchain design projects with forward-looking, growth and practicality, covering blockchain underlying technologies such as alliance chains and distributed storage, as well as blockchain’s applications in manufacturing, agriculture, public welfare, justice, consumption, finance, The implementation of entertainment and other physical industries.

For example, in the field of blockchain infrastructure, the project on the list is the "Blockchain Service Network (BSN)" jointly launched by the National Information Center, China Mobile Communications Group, etc., for deployment and operation areas A global public infrastructure network for blockchain applications can change the current high cost problem of blockchain application development and deployment. In the field of public welfare, the public welfare tracing platform "Public Welfare Searching Chain" launched by Tencent Blockchain and the "Spark Love" project to build a blockchain public welfare ecological mutual aid platform are both on the list.

At the same time, the one-stop "blockchain + industry" service platform "Huolian Blockchain Platform" independently developed by Huolian Technology has also entered the top 20 blockchains. According to the needs of enterprise-level customers According to business needs, select the corresponding smart contract function modules, combine them, and quickly deploy them to enter the blockchain world with zero threshold.

Yuan Ruijuan, COO of Spark Love, a project on the list, said that blockchain technology can improve the current pain points of the charity industry. Xinghuo Love hopes to jointly apply blockchain technology and blockchain governance ideas to public welfare, and actively promote the exploration of the "blockchain + public welfare" field. With this exhibition at the Hi-Tech Fair, we hope that the public can understand blockchain The application of technology in public welfare practice management helps the development of domestic public welfare undertakings.

It is reported that the 2020 Top 100 Innovative Design List and the "Academician Expert Recommendation Plan" were launched in October 2020. It is sponsored by relevant central units and local governments and is widely and continuously carried out across the entire industry across the country. Series of activities. China Communications Industry Association Blockchain Professional Committee, Huobi University and Huobi Labs participated in the selection of the top 20 blockchain technology and application design categories as recommendation institutions.

Blockchain application enters a new stage

Blockchain technology is leading a new round of global technological change and industrial change, becoming the "source power" of global technological innovation and model innovation. Yu Jianing said that only when technological innovation and financial innovation are deeply integrated with the real economy and promote the development of the real economy can the value of innovation be fully realized. Only when blockchain is truly implemented in industrial scenarios can its intrinsic value be demonstrated.

As blockchain technology has been elevated to the national strategic level, blockchain was officially included in the category of "new infrastructure" in the first half of this year. With the support of various policies, the underlying technology of my country's independent intellectual property rights has ushered in a leap forward, and alliance chains, distributed storage, public chains, industry chains, government affairs chains, and custody chains have fully blossomed. Industrial blockchain and chain reform have become social consensus.

"Blockchain applications are about to enter the era of big bang in 2021." Yu Jianing said that this is mainly due to three reasons: First, physical assets will be widely "on-chain", and physical assets on the chain and DeFi (distributed Finance) will further lead the way in empowering real industries with blockchain technology and digital finance; second, the digital renminbi will become a key tool for the digital transformation of enterprises, and the pilot will further drive the digital upgrade of the industry; third, the importance of data protection and digital identity will be highlighted , "new infrastructure" such as blockchain distributed storage will accelerate the historical process of identity digitization and digital assetization.

The Blockchain Professional Committee of the China Communications Industry Association is an affiliated organization of the China Communications Industry Association under the business guidance of the Ministry of Industry and Information Technology. It is the first national-level association in the blockchain industry organization in the country. As an industry educational institution focusing on blockchain applications and digital economic development, Huobi University has provided training for blockchain technology, market, operations and management talents. It is known as the "Whampoa Military Academy of the blockchain industry" and serves as a regional The blockchain industry has cultivated a large number of innovative leading talents. Huobi Labs is committed to building a "blockchain innovation workshop" to provide funding, business, technology, market, human resources, legal, training and other related resources and services to innovative entrepreneurial teams that apply blockchain technology in the real economy.

It is reported that some of the top 20 blockchain companies in this selection also achieved excellent results in the big data and blockchain industry competition of the Innovation Nanshan 2020 "Entrepreneurship Star" competition held this year. It is also a high-potential star project in Huobi Labs Entrepreneurship Camp.

"Today is the year of great development and change in the digital economy. The popularization and application of blockchain will bring about a series of changes. New finance, new business, and new organizations are about to emerge. This time, we will bring blockchain The top 20 projects were unveiled at the China Hi-Tech Fair, hoping to demonstrate the current development results of blockchain technology to the outside world, help the public understand blockchain technology, and establish a broader mass base for promoting blockchain technology to empower the real economy." Yu Jia Ning said.

⑥ Why blockchain investment must not just listen to "actors"

Yesterday, the Boao Asia Blockchain Forum attracted widespread attention. It is not that technology research and development and application design have achieved important results. As a result, it was just because the performances of the special actors on the forum were criticized.

For investors, although blockchain technology will have better development prospects in the long term, if you want to invest in blockchain, you still have to fully Consider the corresponding risks.

Ordinary investors who follow the trend of investment need to pay attention to the fact that many so-called investment projects are actually just pyramid schemes in the name of "blockchain". If ordinary investors enter rashly, they are likely to In the end, they were either "cut off leeks" or fell into a pyramid scheme.

To put it bluntly, blockchain investment must not just listen to the "actors".

⑦ Mars First Line | Tencent Virtual Bank has obtained a Hong Kong license and is preparing for a blockchain virtual bank

Mars Finance APP reported that on November 8, the Second World Blockchain Conference was held in Wuzhen. The conference focused on blockchain, digital assets, central bank digital currency, AI, 5G and other topics, and discussed the application implementation, technological frontiers, industry trends and hot topics of blockchain.

Cai Yige, general manager of Tencent's blockchain business, delivered a keynote speech on "Entering the New Era of Digital Assets" at the meeting, revealing that Tencent Virtual Bank has obtained a Hong Kong license and is preparing for a blockchain virtual bank. Banking Team.

He said that the blockchain is still in the early stage of the explosion of applications. In the large-scale implementation of applications, the blockchain itself is no longer the bottleneck, but the gateway and auxiliary technologies from off-chain to on-chain. is the key, which requires integration with cutting-edge technologies such as the Internet of Things and artificial intelligence.

He also mentioned that the Hong Kong government has begun to regulate digital virtual asset transactions, which has given enough attention to blockchain and digital assets, which is good for the entire industry. Currently, Tencent has digital asset practices in supply chain finance and improving the efficiency of asset and capital allocation, such as its cooperation with McDonald's in supply chain finance and the blockchain electronic invoice developed by Tencent itself.
