The core data of this article: Global blockchain market size, global area Regional distribution of blockchain investment and financing events

The scale of the global blockchain industry is growing rapidly, and application scenarios continue to expand

According to IDC data, in 2020, the scale of the global blockchain market will be stable growth, reaching $4.31 billion. Affected by the new round of regulatory policies on the blockchain industry in European and American countries, the growth rate of the global blockchain market has declined compared with 2019, reaching 53.97%, and is expected to reach US$14.533 billion in 2023.

Equity investment events account for nearly 93%

In 2021, a total of 1,786 investments and financings occurred in the global blockchain. Among them, there were 1,659 equity investments, accounting for nearly 93% of the total investment and financing. In addition, there were a total of 64 mergers and acquisitions, 13 listings and 50 token financings.

Equity investments in the Americas, Europe and Asia are the most active

Judging from the regional distribution of the number of equity investment events, the Americas have the largest number of blockchain equity investments, with a total of 542 in 2021. Pens, accounting for 33%. Followed by Asia and Europe, accounting for 18% and 15% respectively, there is not much difference. overallJudging from the above, the number of equity investments in the three continents of the United States, Europe and Asia accounts for more than 65% of the global blockchain investment and financing.

From the perspective of amount distribution, the amount of blockchain equity investment in the Americas in 2021 reached 128.975 billion yuan, accounting for more than 50%, reaching 56%. In terms of equity investment amount, Europe overtook Asia, accounting for 24% of the investment amount, which was double that of Asia (12%).

The United States "far surpasses Tongji"

At the national level, the United States ranks first with 484 equity investments and a total investment amount of 116.773 billion yuan. Far exceeding the second-placed China with 97 investments and 11.285 billion yuan, Singapore and the UK ranked third and fourth with 91 investments and 88 investments respectively. In addition, the number of equity investments in other countries is less than 50.

The above data refers to the "China Blockchain Industry Market Foresight and Investment Strategic Planning Analysis Report" by the Qianzhan Industry Research Institute.

Ⅲ What is blockchain technology and how does it change business and financial models

What is blockchain technology and how does it change business and financial models? According to reports, since the end of March, the tour guide team led by Yang Feihu has been receiving inquiries from out-of-town individual tourists. "There are many families traveling to Wuhan from out of town. Several families come together by car or by high-speed rail," Yang Feihu said. , Yellow Crane Tower, Hubei Provincial Museum, and East Lake Scenic Area are still places to check in. "It's hard to get a ticket for the Hubei Provincial Museum now, and all the seats for the May Day period have been reserved." He and a number of parents looking for relatives went to Shuidun Town, Zijin County, Heyuan City, Heyuan City. Because Zhang Weiping once confessed that this was the place where Aunt Mei lived, and it was also the place where 8 of the 9 abducted children in the "Aunt Mei Case" were sold.

IV Female scientist Duan Sisi: "Both hands fighting" behind the blockchain "jianghu"

Duan Sisi is at the Institute for Advanced Study of Tsinghua University. (Photo courtesy of interviewee)

Duan Sisi works as a researcher at the Institute for Advanced Study at Tsinghua University. There are very few things in her working place, and the equipment is only three computers. The strange and dangerous offensive and defensive advances and retreats are only brewed in the mind and deduced on the keyboard, and there is no trace of "gunsmoke".

Her research direction is "Byzantine Fault Tolerance Algorithm", which aims to prevent network collapse caused by "enemy destruction" of each node in a distributed system. To put it figuratively, she is engaged in a high-intelligence "hands-on-hand game." The first step is to imagine a possible loophole or "enemy"; the second step is to find a way to make the "enemy" ineffective; the third step is to convince peers that she is solving a "real problem".

Duan Sisi defines himself this way: between a scientist and an engineer. She does not directly "fight" with hackers like a network engineer. She uses the power of mathematics and logic to set rules that make the "enemy" powerless.

“There are bandits among us."Duan Sisi used the term "killing game" to compare the "Byzantine Generals Problem" she studied. "The bandit spreads false news and misleads the good people's judgment, and the battle will naturally be lost. What I want to do is create a protocol that ensures that even if there are gangsters, the good guys don't lose. ”

When the “Byzantine Generals Problem” was proposed in the early 1980s, no one knew what blockchain was. It is the continuous research on this issue that supports today’s blockchain Blockchain technology. Now, China has regarded blockchain as an important breakthrough for independent innovation of core technologies.

At first, the direction chosen by Duan Sisi was a bit unpopular, and people who did not know what was going on thought it was When solving Mathematical Olympiad problems, she also encountered rejections from scientific journals. After the rise of blockchain, people saw the importance of network security protocols, and her academic achievements were seen by more people.

In January this year, Duan Sisi was selected as one of the "35 Technological Innovators Under 35 Years Old" in China by MIT Technology Review in 2021. The reason for the award is that she proposed a number of industry-leading Byzantine fault-tolerant protocols in distributed systems and areas. Outstanding results have been achieved in the fields of blockchain and applied cryptography.

Riding on the express train of emerging technologies, Duan Sisi said that she was quite lucky, but the explanatory power of luck is limited after all. She had no experience during her master’s and doctoral studies. Most of the female classmates did not continue to engage in academic pursuits. The reason that supported her in not giving up was "it's quite interesting."

What made Duan Sisi find interesting was the various ideas she had come up with on her own. Tricky questions. In her opinion, discovering problems is sometimes more important than finding answers.

"Witch Attack", "Hard Fork", "Merkle Tree", "Asymmetric Encryption"... were asked to popularize science When talking about these "black words" in the blockchain circle, Duan Sisi is like pressing the answering machine on a quiz show. He thinks quickly, speaks quickly, and explains the problem quickly.

Duan Sisi studied in the Department of Electrical and Electronic Engineering at the University of Hong Kong. He received his PhD in Computer Science from the University of California, Davis in 2014. After graduation, he worked at Oak Ridge National Laboratory and the University of Maryland in the United States. In 2020, his family Return to China.

“I feel that domestic development is fast and the pace of work is also fast. I am more eager to develop in this aspect, especially in the computer field, although it will be tiring. ” she said.

She is young and promising, has an interesting career, and has a happy family. People around her say she is a “winner in life,” but she thinks her life is “a mess.” She is the daughter of two boys. The mother of a 6-year-old and a 4-year-old. She used to hold her baby with one hand and write code with the other.

She refused to admit defeat when she was young and could not stop doing what she wanted to do. This was also reflected in her work style "Other people can write code piecemeal, but I am used to writing it in one go. ”

To solve a Duan Sisi-type problem requires writing tens of thousands of lines of code, at leastIt will take a few months of work. What this "scientist with a baby" desires most now is a chunk of time. "Once you are interrupted, you will forget what you were thinking when you come back," she said.

Duan Sisi shared an experience about "time management": If you encounter something that can be solved within 5 minutes, then solve it now. It will definitely take more than 5 minutes to put it off later.

Ⅳ How individuals can make money by playing with blockchain

Newbies who don’t have much spare money but want to make some big money, follow social groups such as Huolian Blockchain Academy For a fee of several thousand yuan, you can make more than ten times the profit when the market comes; those who make the least money only buy Bitcoin and Ethereum, so the risk is small.

VI Direct to Digital Expo丨Blockchain Standardization and Application Innovation Summit released three innovative results

Zhang Ping, chief engineer of the Cyberspace Administration of Hebei Provincial Committee, introduced that blockchain is the One of the hot spots focused on at the Expo was the "Hebei Province Blockchain Special Action Plan (2020-2022)" released by Hebei Province last year, which clarified Hebei Province's blockchain technology and industrial application development goals - by the end of 2022, Hebei Province There are 20 leading companies and leading companies in blockchain-related fields, cultivating a number of blockchain application products, striving to create 1-3 nationally renowned blockchain brands, and forming 3 blockchain industry clusters with regional influence. Park, the competitiveness of the blockchain industry ranks among the top in the country. To this end, Hebei Province is committed to introducing well-known domestic and foreign enterprises, gathering the most advanced technology, the most cutting-edge innovative concepts, and the most high-end human resources to cultivate innovative forces for the development of Hebei's blockchain industry.

"Hebei Provincial Characteristic Agricultural Products Blockchain Traceability Platform" was jointly developed by the Institute of Applied Mathematics, Hebei Academy of Sciences and Huaye Hebei Co., Ltd. Wang Zhiqiang, deputy director of the Institute of Applied Mathematics of the Hebei Academy of Sciences, introduced that the platform fully integrates blockchain with big data, Internet of Things, artificial intelligence and other technologies to realize the full chain traceability of production, logistics and sales information of specialty agricultural products, making production Operators, the public and regulatory authorities can participate together to build brands, enhance product value, and promote high-quality development of the agricultural economy.

It is reported that the “Hebei Province Specialty Agricultural Products Blockchain Traceability Platform” has three most prominent features:

First, one vote, one code, and object code locking. Intelligent identification and matching of business entity information and sales documents effectively solves problems such as multiple data sources, poor quality, and inconsistency between upstream and downstream.

Then there is the whole-chain evidence storage and accurate traceability. With the traceability code as the carrier and responsibility and flow management as the core requirements, agricultural product circulation data, electronic vouchers and other information are uploaded to the chain to achieve functions such as data non-tamperability and transaction traceability, and improve data throughput through the standardization of data storage and exchange. Key performance indicators such as volume and system response speed.

The third one is multi-source fusion and targeted regulation.On the basis of the blockchain system, for the characteristic agricultural product industry chain, a fusion model of production, circulation and inspection big data has been established to achieve targeted supervision and intelligent decision-making based on big data analysis, and comprehensively enhance the brand of on-chain products. Credibility.

"After three months of trial, the platform has been connected to 212 agricultural product trading markets, 9,807 online merchants, and 3,484 on-chain varieties, demonstrating strong application demand and development potential." Wang Zhiqiang introduced that the Hebei Academy of Sciences is also exploring another high-quality route, cooperating with the Julu County Government to promote the "One Flower Supports Hundreds of Industries" project, using "blockchain empowering agriculture" as the entry point to create an agricultural digital estate, and then drive the development of agricultural digital estates. The integrated development of primary, secondary and tertiary industries in the county will eventually achieve the goal of "one flower blooming and all industries prospering".

This Blockchain Standardization and Application Innovation Summit is hosted by the China International Digital Economy Expo Organizing Committee and hosted by the China Electronics Technology Standardization Institute, the Software Institute of the Chinese Academy of Sciences, and the Hebei Academy of Sciences.

Ⅶ What blockchain traceability projects are there in Sichuan?

Tracing is one of the important application scenarios of blockchain technology. For consumers, food safety is a major matter related to life and health, so we now have higher and higher requirements for food quality. Since blockchain technology is non-tamperable, it can record the entire life cycle of food, making us feel more confident about what we eat.

So what blockchain technology traceability platforms are there in Chengdu? The editor has collected information from many sources and collected the blockchain traceability platforms in Chengdu as follows:

Lianbo Technology’s XTrace traceability

According to the official website of Lianbo Technology, this product has Botai quality control and traceability reached cooperation. This project is a quality traceability system initiated by the Provincial Food Quality and Safety Collaborative Innovation Center of Xihua University. Lianbo Technology has added the blockchain bottom layer to its original traceability system, making all traceability information non-tamperable and easy to locate. , which improves the reliability and credibility of the traceability system. At present, the traceability system has been connected to famous upstream and downstream brands such as Wudongfeng, Dancheng, and Jixuan.

China Cybersecurity’s Xinlianzhen product

China Cybersecurity launched the “Xinlianzhenzhen” product together with insurance companies, testing companies, e-commerce platforms and other institutions. "Product" has been implemented in agricultural products such as Chengdu kiwi fruit and tangerine, providing reliable traceability services for high-quality agricultural products.

Fertilizer traceability in Sichuan Rundi

Sichuan Rundi Agriculture Co., Ltd.’s application of blockchain traceability is mainly in pesticides and fertilizers. Using correct information sources or on-site sensors, now The non-central collection and processing of information on land production links has been realized.

Sichuan Zhenxuan Traceability

Sichuan Zhenxuan Traceability makes full use of Internet technology and the method of integrating ecological agriculture to break the traditional agricultural sales by building an online product base. concept, consumers can have a comprehensive understanding of the entire production process.

Then these are probably the blockchain traceability platforms in Chengdu. I believe that blockchain traceability can develop better and better!

Ⅷ If you want to promote overseas blockchain, what should you do?

If you want to promote overseas blockchain, what should you do?

You can consider looking for BoZhan for overseas communication.

If you want to do blockchain advertising and promotion, is there any precision marketing platform?

You can consider Xiacheng Outer Circle, which has a dedicated blockchain industry promotion solution, integrates more than 10 types of media relations resources with more than 3 million W, and is said to be good at precise advertising.

Why does funsworld launch blockchain K assets?

Because blockchain has three major advantages: openness and transparency, collective maintenance, and reliable database, it has broad prospects and huge market potential, so they launched this electronic currency.

How to learn blockchain

Blockchain has become crazy, but you know nothing about it!

Blockchain is a decentralized database system participated by different nodes and an open ledger system.

It consists of a series of data blocks or data packets generated according to cryptographic methods, that is, blocks. The data information of each block is automatically stamped. Timestamp, thereby calculating a data encryption value, that is, hash value (hash).

Why does Panyubao launch the blockchain delivery function?

It should be for a better user experience

How to play foreign exchange when blockchain comes

How to play it specifically, Tiger Foreign Exchange has done a good job in this aspect of the industry

How to prevent counterfeiting in blockchain ? How to spot fakes?

They will record the production information, logistics information, sales information and other data of the product. It is equivalent to a person having an ID card, but this ID card is a code. After entering, you can see very complete information. Even your "parents" know your net worth and name, and they can't change it! With this kind of blockchain for anti-counterfeiting and traceability, even the labor cost of printing is saved.

After reading the previous content of Blockchain Three Plus One, what are the ways to promote blockchain?

From traditional promotion to offline and online methods, it mainly describes the different methods of promotion in entities and on the Internet. The main promotion of blockchain is through e-commerce online promotion channels (database marketing, social media marketing, online advertising, mobile clients, distribution platforms, search engine marketing, resource cooperation marketing, classified information, etc.). The models are always changing, but they remain the same. Regardless of the promotion channels, they all serve a common goal: profit.
The above are purely personal thoughts.

Blockchain, what kind of project is it? How to do it?

I have been studying blockchain for a long time and have learned about several projects. You can discuss it.

How to learn blockchain

Take two steps, the first step is to determine the direction, and the second step is to determine the details. .There are several directions: I'm just a novice who wants to know what it is.

I want to work in the blockchain industry, doing development, operations, products, and even blockchain entrepreneurship.

The details of each direction are purple:

Direction 1

I want to understand what the blockchain is and what the various coins do.

Let’s start with Bitcoin. Here we recommend "Bitcoin" edited by Li Jun, Chang Chai, etc., which can help you understand the consensus wisdom behind Bitcoin, the principle of decentralization, the history of Bitcoin, etc. Next, let’s research various currencies. The larger domestic chains include QTUM and NEO, and the larger foreign chains include EOS, ETH, etc. Go study their white paper, team, history, itter, telegram group and other places where you can get in touch.

At the same time, you also need a place where you can watch the market, exchange ideas, and read articles. Here are some commonly used apps recommended. For example, the commonly used APP blockfolio for checking prices; for checking information, block news, news, and even finding a place to brag, you can use the Baweiyuan APP; for currency information, you can refer to the Feixiao APP, which has quite a lot of content. Among them, Ba Weiyuan APP is the one I use most because its news is reliable and will not be faked.

Direction 2

Blockchain industry

As far as I know, most of the current practitioners in the blockchain industry have transferred from finance or computer majors. If you are a college student and want to work in the blockchain industry, you may consider majoring in finance or the computer industry. If you are already working and want to join the blockchain industry, then you need to learn the following content. This book "Blockchain: From Digital Currency to Credit Society" by Chang Chai and Han Feng will introduce you to the basic knowledge of blockchain. "Blockchain Technology Guide" can help you deepen your understanding of blockchain technology. "Blockchain Revolution" can take you into a revolution that is about to happen. Overall, there is a lot to learn.

Ⅸ Does blockchain really have development prospects?

There is no doubt that blockchain has development prospects, and the necessary condition for development prospects is to enter the mainstream market.

Matt Spoke, founder and CEO of North American blockchain infrastructure The OAN (formerly Aion Network), published an article in Forbes on July 24 titled "In order to successfully enter the mainstream market, blockchain projects must "Eat Dog Food", in which Matt mentioned his views on how blockchain should enter the mainstream market - "Eat Dog Food".

In the technology circle, there is a jargon called "dogfooding" (also known as eating your own dog food), which refers to a company using its own products and becoming a user of its own products. Many high-growth companies (such as Microsoft, Facebook, AsiaAmazon, Apple, Netflix and Google) will also use dog food to test products or help products build credibility. Although "eating dog food" is often used to find and fix bugs, it has another value: creating reliable use cases for the company's products.

This is worth learning from blockchain projects, because blockchain projects often hold the idea of ​​"if it is built, they (users) will naturally come" and habitually create new and interesting things. Responsibility for blockchain applications is given to third parties.

This attitude is so common that even the well-known blockchain summit Consensus 2019 (2019 Consensus Conference) also held a conference titled "Build it, they (users) will naturally come: Creating a global area" Blockchain Center's roundtable forum discusses how governments around the world can make efforts to attract blockchain projects while balancing regulatory, investment and innovation needs.

To be fair, this strategy may be effective for blockchains that only target cryptocurrency circles. For security tokens, especially exchanges that trade such representatives, this makes even more sense - "supply creates demand" is the usual thinking here, especially considering the complex infrastructure required to implement these transactions. .

In contrast, "eating dog food" is more likely to be used by blockchain project developers seeking mainstream audiences (such as those in the financial industry, manufacturing and supply chain, identity management, etc.) use. If blockchain technology wants to break into these mainstream fields, blockchain companies must first "eat dog food." This will not only clearly prove that blockchain technology is feasible outside the currency circle, but also highlight that blockchain can not only optimize existing use cases, but also create new use cases.

The OAN team has always adhered to this concept and relied on the technology stacks of The OAN and Aion built over the years to develop Moves, a financial technology platform for independent workers.

Matt said that when developing the Moves product, the team hopes that the relevant functions of The OAN blockchain network can be fully utilized, so the focus will be on the following three aspects:

p>

1. How to use The OAN blockchain network to improve the credit efficiency of products.

There are two main considerations for improving credit efficiency: 1) Can Zheng Lu learn from the mechanisms of the DeFi market to reduce capital costs; 2) Can blockchain technology be used to increase the external credit process for Moves? of trust. Here, Moves will form a "pooling of wisdom" mechanism, allowing everyone to contribute to reducing credit risks and increasing the credibility of the credit granting process, and may even develop a micro-guarantee mechanism in the future. Therefore, users will be able to participate in the market established by the platform as a borrower, lender or guarantor.

2. How to align the interests of products and users.

Specifically, by combining Moves with The OAN network connection, with the help of the digital asset Aion, a relationship of consistent interests is formed between the product and the user, so that the user can personally experience the success of Moves product development, and at the same time directly participate in the area that supports Moves. Blockchain network - The OAN.

3. How to create a pioneering financial reputation data open system with Moves.

This open system may become a replacement for traditional credit scores or related mechanisms. For years, banks and financial institutions have used scores from Equifax, FICO or others as risk indicators, and the Moves team believes that the product it is building will be a good start - a better, more modern financial system. The beginning of the reputation system. This is a long-term goal.

Moves supports mainstream ride-sharing, food delivery and other gig economy concept platforms in North America and will be the flagship open application developed by The OAN on its blockchain network. In June, Moves' business operations expanded from Ontario to two more provinces - Alberta and British Columbia, and into Western Canada.

The various measures taken by The OAN team are all based on the spirit of "eating dog food" and working hard to allow blockchain technology to enter the mainstream market as soon as possible. Blockchain is not for the niche, but for the mainstream. In addition to The OAN team, many projects and institutions in the blockchain industry are also moving towards this goal. With such an excellent and targeted blockchain, what can you do? Are you saying there is no development prospect?
