1. What signals does the blockchain 3.0 era give us?

2017 is the first year of the outbreak of blockchain, and 2018 will be the first year of the implementation of blockchain.

What kind of changes has the blockchain brought to the world from the 1.0 era to the 3.0 era?

The development of blockchain can be divided into three stages: peer-to-peer transactions, smart contracts and pan-blockchain application ecology (Token economy)

Blockchain 1.0 Era: Digital currency return rate is king

The 1.0 era now mostly refers to the digital currency era centered on Bitcoin. Digital currency transactions are the most important form for people to participate in the blockchain. At this stage, few people really pay attention to the application value of digital currency, let alone the practical value of the blockchain technology behind it. People focus on the rate of return of digital currency, which is equivalent to buying a stock on a different market, but this "stock" is relatively Active, the rate of return is astonishing, and of course it is also full of disasters.

Blockchain 2.0 era: smart contracts provide infrastructure support for upper-layer application development

The "smart contract" era is the real Programmable blockchain, usually represented by "Ethereum", supports Turing-complete scripting language at this stage, providing the necessary infrastructure for developers to develop any application on the "operating system" they set, realizing The actual application of virtual world has been implemented. The biggest contribution of Blockchain 2.0 is to completely subvert the concepts of traditional currency and payment through smart contracts. In the era of Blockchain 2.0, the blockchain has formed a trust foundation based on its traceability and non-tampering characteristics, providing a basis for smart contracts. A trustworthy execution environment makes it possible for contracts to be automated and intelligent. The biggest difference between smart contracts and traditional contracts is that they are not restricted by real social laws. For the contract subject to automatically execute the agreement after triggering the contract terms, the arbitration platform no longer determines the execution results in the smart contract but assumes responsibility. Responsibility for execution

Blockchain 3.0: The disruption to business lies in its transformation of production relations

We are now at the junction of the 2.0 era and the 3.0 era. The 3.0 era can be called It is people's ideal vision for the future virtual digital currency economy. In blockchain 3.0, people can truly realize assets on the chain, build a variety of applications within a large underlying framework, and create a seamless A platform with trust costs, super transaction capabilities, and extremely low risks can be used to realize the increasingly automated distribution of physical resources and human assets around the world, and promote large-scale collaboration in science, health, education and other fields.

Blockchain 2.0 builds infrastructure such as digital identity and smart contracts. On this basis, the complexity of the underlying technology is hidden, and application developers can focus more on application logic and business logic level. That is to say, we have entered the blockchain 3.0 era.The sign is the appearance of Token. Token is a value transmission carrier on the blockchain network, and can also be understood as a pass or token.

Token’s greatest impact on human society is its transformation of production relations. Joint-stock companies will be replaced, and every actual participant becomes the owner of productive capital. This new type of production relations encourages every participant to continuously contribute their own productivity, which is a great liberation of productivity. If this business activity is mapped to inflation in real society, as long as the former outperforms the latter, every Token holder will make a profit over time.

It is too early to talk about Blockchain 3.0. Although Blockchain has gone out of the conceptual stage, the current status of Blockchain technology development is that the underlying technology is still It is not mature enough and its applicable scenarios are relatively limited. On the one hand, there is still room for optimization and improvement in core blockchain technologies such as consensus algorithms; on the other hand, the processing efficiency of blockchain is still difficult to meet the requirements of some high-frequency application environments in reality. Moreover, the current mainstream blockchain technology platforms all originated from abroad. Domestic blockchain technology service providers must patiently start from the bottom development, achieve independent and controllable technology, and strive to lead the development of global blockchain technology. time period.

Competing among the heroes, the company that laughs last must be the company that really focuses on researching technology and developing practical applications! According to my observation, among the various applications based on Ethereum, the SEC social e-commerce chain has a very high chance of being implemented, and it is likely to become a killer application. There is a weekly report on the SECblock official account, which shows that the team is working hard.

2. Blockchain Encyclopedia: The Past and Present of Blockchain - 3.0 Era

The representative of the blockchain 1.0 era is Bitcoin, and the representative of the 2.0 era is Ethereum. And the troubled times of various copycats and air coins. Blockchain 3.0 is the era of consumer-level blockchain that has truly entered commercial applications and physical applications after the troubled times. The typical symbol is the emergence of tokens. The pass has brought about changes in traditional business models and production relations. The pass has moved from the digital world to the real economy and has begun to seek practical applications in various industries.

The pass has three elements, one of which is indispensable.

Pass: The pass can be circulated on a large scale in a network and can be verified anytime and anywhere; Certificate: As a proof of digital rights and interests, the pass must be a certificate of rights and interests that exists in digital form, and it must represent It is a right, an inherent and intrinsic value; value: the token must have economic value.

In this way, the meaning of "token economy" is not difficult to understand. The token economy is a large-scale group collaboration based on tokens. It maximizes the role of tokens, allows every role that creates value to share value fairly, fully mobilizes participation motivation, and forms a self-organizing form.

Major changes in the blockchain 3.0 era

The token economy has laid a theoretical basis and technical support for the large-scale application of blockchain, and the future world will also be transformed on a large scale. Changes include:

1. Fragmented investment, fragmented income, subverting the traditional way of doing business on the Internet. In the traditional Internet era, it was impossible for ordinary people to participate in the investment of a company, but the emergence of blockchain allows ordinary people to make fragmented investments in a large asset. Assuming that Alibaba originally adopted blockchain for fragmented investment, then all fragmented shareholders who invested in Alibaba would be able to reap a return on investment that has increased thousands of times today!

2. Break the money-burning model of the Internet and make everyone a winner. The free model of the traditional Internet is essentially to obtain a large number of users through free products to form monopolies and barriers, and then make profits through advertising and value-added services on this basis. In the blockchain 3.0 era, project income is redistributed by issuing tokens to attract more early investors and community users. As the number of users holding tokens increases, the value of the tokens will become higher and higher, and community users, investors, and projects can all benefit from it. In this way, the money-burning model of providing free services in the early days of the traditional Internet can also be improved, and everyone will become a winner.

3. Breaking down the traditional corporate organizational hierarchy, self-organization may become a future trend. In the blockchain 3.0 era, through the establishment of distribution and collaboration mechanisms through smart contracts, it can be more efficient and accurate than enterprises. All token owners will naturally form a community. Everyone has the same goal - "to promote the development of the project and make it a success". They are all members of the community, contribute to the community, promote the value-added of the token, and thus gain benefits together. profit. From a philosophical perspective, this new self-organizing community of freedom, independence, and equality must be the future trend. Gojoy blockchain e-commerce is a blockchain self-organized community. Every consumer is a token owner and a fragmented investor, so he is very happy to co-create and build Gojoy value.

Therefore, we can look forward to the era of great development of the blockchain 3.0 token economy, and the existing ones may be subverted. What we need to be prepared for is to work hard to embrace the blockchain. If you want to seize the trend of blockchain and understand how to transform into blockchain, please leave a message to communicate and we will take you to learn the blockchain professional certification course.

3. Is the founder of 360 Zhou Hong_?

“The inventor of the word superuniverse is amazing. This concept can be so broad that everyone thinks they don’t understand it, but It can be popularized so that everyone can speak it. No matter what you do, you can label yourself as super-universal." On December 28, 360 Chairman Zhou Zhou was at the "3354360 Group Strategy Conference to Open the First Year of Digital Security" Said, "I likeI like the word "happy", but do you think I really understand the metaverse? No one knows, but that doesn’t stop us from talking about the word at all. Academicians have their own understanding, doctors have their own understanding, and I have my own understanding. "

The universe is a basket that everyone can fit into.

"I've been crazy about the Metaverse for a while, and I started reading multiverse material in awe," Zhou said. "The Metaverse is in good shape. It's a big basket where everything can go. Some people put VR stuff in it, some people put community stuff in it, and I put industrial Internet stuff in it. Therefore, everyone can talk about the metaverse, and everyone can be a metaverse. Just don't make it the preserve of a few big companies. "

Zhou revealed, "I have read reports written by many investment banks, and each bank has its own understanding. In reality, I have also talked with many companies called Super Universe 2. As the saying goes, there are a thousand Hamlets in the hearts of a thousand people. Now I can say that there are ten thousand metaverses in the hearts of ten thousand people."

Although the basket of superuniverses is very large, Zhou still made a rough classification, namely the game school, the stock market school, the currency speculation school, and the virtual school. The world school and the digital twin school. After the word "super universe" became popular, many companies came forward and said that we are also related to the super universe, such as servers, chips, graphics cards, switches, clouds, big data, and databases. All Manufacturers related to digital technology are actually related to the Metaverse. These people are not lying. It is true that the Metaverse needs service machines and cloud computing. This is the industrial chain that builds the foundation of the Metaverse. Caution is the label of the Metaverse , the stock prices of many companies have skyrocketed, so much so that the China Securities Regulatory Commission has inquired about many companies. I call this school the stock market school."

In Zhou's classification, he was regarded as a digital twin by Bi Jing, but he also admitted that " "Digital twin" is too weak. "I'm very touched. All our colleagues in communication should think about it. The digital twins and industrial Internet that we have been talking about for so long are not as powerful as the super universe."

Zhou’s own answer is, “The core of the industrial Internet is digital twins. In my understanding, twin numbers and the metaverse are basically the same thing. But the term “digital twin” is too professional and technical, so there is no It has become a hot word among ordinary people. But the word metaverse describes digital twins from another perspective, making it easier for ordinary people to perceive and accept."

The network shows that digital twins refer to making full use of physical models, sensor updates, Operation history and other data. Integrate multi-disciplinary, multi-physics, multi-scale, and multi-probability simulation processes and complete mapping in virtual space to reflect the full life cycle process of the corresponding physical equipment. A digital twin is a concept that transcends reality and can be viewed as a digital mapping system of one or more important and interdependent equipment systems.

The network security industry should be upgraded to a digital security industry.

In Zhou's view, no matter what is in the basket of the super universe, safety will only become more and more important. "The super universe or industrial Internet can make the entire human society smarter, but it will also make it more vulnerable in terms of security."

Zhou believes that regardless of Yuan YuThe universe is still digitizing the industry, and the ultimate core of business is the big data system. Once the big data system is paralyzed, all businesses will be paralyzed. “Imagine everyone, in the metaverse era, I will only talk about a few scenarios, such as critical infrastructure, industrial Internet, Internet of Vehicles, energy Internet, digital finance, digital currency, etc. Each scenario is extremely complex and is not a traditional security product or Technology can solve it. For example, although blockchain says it has algorithmically proven itself secure, many blockchain exchanges have had numerous security issues in the past two years, resulting in large amounts of digital currency being stolen. That is to say , As long as these technologies are based on code and software, there will be loopholes. No matter how high the programmer’s level is, as long as he writes a thousand lines of code, there must be 4-6 loopholes.”

Therefore, Zhou The concept of "digital security" was put forward, that is, "network security" should be upgraded to "digital security", "I think 2023 should be the first year of digital security."

Introduction: Zhou Hong_, male, was born in Henan Province, China in 1970. He graduated from the Department of Computer Science, School of Telecommunications, Xi'an Jiaotong University. Founder and CEO of 360 Company, well-known angel investor. Main achievements: Founded Qihoo 360 listed company. His representative works include "My Internet Methodology" and "Rejecting Mediocrity". In 2014, he won the title of China Internet Person of the Year. In 2016, he served as the third chairman of the Beijing Intellectual Property Protection Agreement. In 2016, he ranked eighth in the Entrepreneur Writers List, a new sub-list of the 10th Writers List.

Related Q&A: What kind of person is Zhou Hong_, President of 360?

Zhou Hong_ was born in Qichun County, Huanggang City, Hubei Province in 1970.

When he was a student, he was always very good and hard-working. After receiving his undergraduate degree from the Department of Computer Science, School of Telecommunications, Xi'an Jiaotong University, due to his excellent academic performance, he was recommended to Xi'an Jiaotong University to continue his postgraduate studies in the Department of Systems Engineering, School of Management.

In 1998, 28-year-old Zhou Hong_ founded Beijing 3721 Technology Co., Ltd., and in the same year launched the Chinese website, the predecessor of 3721 "Internet Real Name", pioneering Chinese Internet services. In 2003, the company was acquired by Yahoo, and soon Hong Zhou became the president of Yahoo China. But after just 18 months, Zhou launched Yahoo.

In 2006, Zhou Hong_ invested in Qihoo 360 Technology Co., Ltd. and served as the chairman of Qihoo 360. Later, he launched free security software-"360 Security Guard". Over the years, he has been bombarded all the way, making sudden advances in the east and west. When it landed on the New York Stock Exchange 6 years ago, 360's market value exceeded 10 billion US dollars, becoming the top 3 Chinese Internet companies in terms of market value.

But in December 2015, Qihoo 360 announced that it had reached a final privatization agreement with a buyer group, and the buyer group would acquire Qihoo 360 for US$9.3 billion in cash. In July 2016, 360 Company announced the completion of privatization transaction, delisting from the New York Stock Exchange.

In November 2017, after "hibernating" for a period of time, Zhou Hong_ finally took 360 officially returned to A shares. At the media briefing on Jiangnan Jiajie's major asset restructuring held in the trading hall of the Shanghai Stock Exchange, Zhou Hong_ appeared wearing a red Polo shirt. However, unlike the glory of the year, when 360 returned to the A-share market, the world had already changed.

At any time, Zhou Hong_ is a person who knows what he wants to do. In "The Subversive: Zhou Hong_Autobiography", it is written that at a class meeting in the second year of high school, the class teacher asked everyone to talk about their ideals. Zhou Hong_ walked up to the podium and delivered his only speech about ideals:

"My ideal is very clear. I will be a computer software developer in my life. Make a product and change the world."< p>Today's Zhou Hong_ is also constantly changing under the wash of the Internet wave. In addition to security software, he also began to develop new products, because Zhou Hong_ knew: "In China's Internet arena, it is quite difficult. If you don't enter other people's territory, others will enter your territory; if you If you guard a territory and don’t go anywhere else, and others don’t come, it means that this land is quite desolate.”

4. In what project did the earliest blockchain technology appear?

Bitcoin project.

The earliest prototype of blockchain technology appeared in the Bitcoin project. As the distributed accounting platform behind Bitcoin, Bitcoin has been running stably for nearly eight years without centralized management. , supports massive transaction records without serious vulnerabilities. The world-recognized blockchain technology began in 2008.

Feature Introduction

Under the consensus mechanism, only when most nodes in the entire network believe that the record is correct at the same time, the authenticity of the record can be Only with the approval of the entire network can the recorded data be written into the block, ensuring the data integrity of the information.

Blockchain is an immutable technology. Each block is linked to the previous block through cryptographic proof. To modify the transaction content in a historical block, you must combine the transaction records and cryptography of all blocks before the block. The proof is reconstructed, which effectively prevents data tampering.

5. What is blockchain

In the simplest terms, blockchain is a distributed ledger.

To understand what this means, we first have to look at its opposite: a centralized ledger. Because blockchain technology started with finance, we will also introduce it below using banks as an example.

The following is our process for using bank debit card transactions:

You can swipe your card to purchase goods in stores.

The merchant sends a statement to your bank for the agreed upon amount.

Your bank will verify that you may have authorized the purchase.

The bank sends the money to the merchant.

Finally, the bank records this information in its ledger.

There's a lot of technology involved here, but that's basically it. The last step is important - the bank records all transactions made by the customer. This ledger goes all the way back to the first transaction the bank made.

This ledger is kept, maintained and regulated by the bank. You can read it in your online bank account, but you can't change it. The bank has complete control. If it decides to make a change, there's nothing you can do about it.

Crucially, if hackers were able to access a bank’s ledger, that could cause a lot of problems. They can change the account balance to make it look like certain transactions never occurred, etc.

This is why distributed ledgers are so cool.

Blockchain Network Visualization

If a bank operates on a distributed ledger, each member of the bank will have a copy of the ledger, and whenever any member of the bank When they make a purchase, they tell every other member of the bank.

Each member will validate the transaction and add it to the ledger (the added records are called "blocks"). This has some important benefits, as there is no centralized authority that can manipulate records. Hackers accessing one ledger won't be a big problem because other ledgers can easily verify it.

On the other hand, it requires a lot of work. In short, the second system is blockchain (at least in financial scenarios).

As mentioned above, blockchain is a decentralized list of transactions. If I send Xiao Ming 2 Bitcoins, I send a message to everyone in the network saying "I am sending Xiao Ming 2 Bitcoins" and they all record the transaction.

The future of blockchain, how will it change our lives?

One thing that is important about blockchain is that it is a public resource and no one really owns it because everyone owns it.

Blockchain is not just science fiction. We don’t need to understand the mechanism behind this technology, but you do need to understand that it may completely change our lives in the next 20 years.

This may sound bold, but remember, 20 years ago we were browsing the Internet on Netscape, using state-of-the-art Motorola flip phones, and buying our first DVD players. At that time, if we imagined that a computer could be held in our hands and that we could buy cars, make payments, and watch movies, it would have been considered a fantasy.

Although the impact of blockchain may not be as obvious as the Internet, nor as tangible as mobile phones, blockchain will effectively solve many worries in daily life. Such as intermediaries cheating people, transaction delays, etc. In our current lives, middlemen are everywhere and we take them for granted as a part of life. If one day these intermediaries cease to exist, you will find that the world willBecome something else.

Imagine that by 2040, blockchain may become a mature and widely used technology. When one day you can't live without the blockchain just like you can't live without the Internet now, you will be surprised to find that this decentralized accounting technology has simplified the complexity and become a part of your lifestyle

6. What happened when 360 discovered epic vulnerabilities in the blockchain?

Recently, the Vulcan team of 360 Company discovered a series of high-risk security vulnerabilities in the blockchain platform EOS. It has been verified that some of these vulnerabilities can remotely execute arbitrary code on EOS nodes, that is, they can directly control and take over all nodes running on EOS through remote attacks.

In the early morning of May 29, 360 immediately reported this type of vulnerability to EOS officials and assisted them in repairing the security risks. The person in charge of the EOS network stated that the EOS network will not be officially launched until these problems are fixed.

EOS super node attack: virtual currency transactions are completely controlled

In the attack, the attacker will construct and publish a smart contract containing malicious code, EOS The super node will execute this malicious contract and trigger the security vulnerability in it. The attacker then uses the super node to package the malicious contract into a new block, which in turn causes all full nodes in the network (alternative super nodes, exchange deposit and withdrawal nodes, digital currency wallet server nodes, etc.) to be remotely controlled.

Since the attacker has completely controlled the node system, the attacker can "do whatever he wants", such as stealing the key of the EOS super node, controlling the virtual currency transactions of the EOS network; obtaining other financial information in the EOS network participating node system. and private data, such as digital currencies in exchanges, user keys stored in wallets, key user information and private data, etc.

What's more, attackers can turn nodes in the EOS network into members of the botnet, launch network attacks or become free "miners" to mine other digital currencies.

7. Which relevant departments in Shandong have taken action to lay out the blockchain project

Ten years have passed since the blockchain was proposed. In the past ten years, under the guidance and support of relevant domestic departments, blockchain has penetrated into various industries. Since 2017, the State Council and the Ministry of Industry and Information Technology have repeatedly proposed to actively promote domestic blockchain research, standardization development and industrial application in related fields. However, blockchain has not yet developed on a large scale in Shandong. Through mainstream search engines such as the Internet and 360, searching for keywords such as "blockchain + Shandong" can reveal some related deployment documents and policies in addition to blockchain. Except for support and a few companies that provide blockchain technology services, there are almost no specific application projects of blockchain. In recent years, relevant departments of the Shandong Provincial Government have also been actively promoting and deploying blockchain project construction.

➨On December 27, 2018, the Shandong Provincial Development and Reform Commission issued a notice on the "Shandong Provincial Producer Service Industry Development Layout Plan", aiming to accelerate the innovative development, sustainable development and leadership of Shandong Provincial Producer Service Industry develop. In the layout of the software and information technology service industry, it is emphasized that Jinan, Qingdao, and Yantai are the core nodes, focusing on the development of 12 industrial directions such as artificial intelligence and blockchain. Zhongzhexin Blockchain Co., Ltd. follows the layout planning trend of the Shandong Provincial Development and Reform Commission , actively layout and explore the application of blockchain in the real industry.

➨On October 28, 2018, the "Special Plan for the New Generation Information Technology Industry in Shandong Province (2018)" was issued by the General Office of the People's Government of Shandong Province and implemented by the Department of Industry and Information Technology of Shandong Province and other relevant departments. -2022), the notice emphasizes that we must grasp the development trend of the new generation of information technology industry, adhere to advanced layout, innovative leadership, and solidly promote disruptive technological innovation in cutting-edge fields such as artificial intelligence, quantum technology, virtual reality, and blockchain. , seize the opportunities and commanding heights for the future development of the industry. In exploring and promoting the development and application of blockchain technology, specific requirements are put forward, requiring accelerating the research and application of key technologies such as blockchain architecture, consensus algorithms, asymmetric encryption, fault-tolerance mechanisms, distributed storage, etc., to form blockchain infrastructure and solutions . Actively promote the in-depth integration of blockchain with big data, cloud computing and other technologies, expand blockchain application scenarios, and strengthen the application of blockchain technology in key industries such as finance, industry, energy, and medical care.

In addition to various notices and layout plans, relevant provincial departments are also actively implementing the cooperation and construction of blockchain projects. On June 28, 2018, the Shandong Provincial Department of Commerce and SF Express Group signed a strategic Cooperation Agreement. The two parties will use their respective advantages to cooperate in areas such as the construction of modern supply chain systems and promote the integration of blockchain and other technologies with supply chains.

➨On July 26, 2018, Xie Weijun, Director of the Shandong Provincial Department of Justice, stated that blockchain technology should be promoted in related fields, explore the implementation form of "blockchain + judicial administration", and promote "district "Blockchain" technology is applied in judicial administration fields such as community corrections, notarization, and forensic appraisals.

The development of blockchain also requires the supervision and supervision of more departments, including the Office of the Network Security and Informatization Committee of the Shandong Provincial Committee of the Communist Party of China, the Shandong Provincial Communications Administration, and the National Computer Network and Information Security Management Center. The "2018 Shandong Province Network Security Report" jointly released by the Shandong Branch pointed out that the security problems brought about by new technologies such as 5G, IPv6, and blockchain will become increasingly serious. The Shandong Provincial Administration for Market Regulation (Intellectual Property Office) also provides services and supervision in industrial and commercial, intellectual property and other aspects.

Zhongzhexin Blockchain Co., Ltd. actively responded to the call of the Shandong Provincial Government, based in Jinan, relying on entities, and took the lead in creating the country's first tea blockchain project in Shandong, striving to create a new generation of information in the country A new frontier of technological development. Tea Chain World is based on blockchain technology and is a tea blockchain application that integrates artificial intelligence. It uses the characteristics of blockchain decentralization and trustlessness to achieve point-to-point interaction and transactions between the supply end and the consumer end. On the one hand, It solves the problems of enterprise operating costs, inventory, sales channels, etc.; on the other hand, the characteristics of blockchain such as non-tampering and traceability solve product quality problems. Products can be monitored in every link from source, production, processing, distribution to the hands of consumers. .

The tea chain world has introduced tokens, using blockchain token incentives to break the original business model and reshape the production relations of the tea industry. passThe consensus mechanism allows each participant in the chain to collaborate with each other to jointly create value, share corresponding rewards and equity certificates according to their contribution, greatly mobilizing the enthusiasm and creativity of participants, thereby creating more value and fully stimulating The economic vitality of individuals and enterprises promotes the economic growth of industries. Taking real enterprises as the starting point and starting from the tea industry, it will drive the development of the real economy. Tea Chain World has realized all possibilities for the innovative development of tea companies, and has played a positive leading role in leading China's tea industry to new heights.

8. What stages has the blockchain developed?

The blockchain has developed in five stages
1. Germination stage: The real germination stage of the blockchain was in 2007 By 2009, a Japanese-American with the pseudonym Satoshi Nakamoto first described a new fantasy report on electronic currency on a cryptography discussion group in 2008 under a different name. Since then, Bitcoin has been born. As early as 2007, Satoshi Nakamoto began to explore a series of new technologies with the intention of creating a new currency. The Bitcoin white paper was released on October 31, 2008, and the Bitcoin system officially began operation on January 3, 2009.
The main technologies supporting the Bitcoin system include hash functions, distributed ledgers, blockchain, and asymmetric encryption; it can be seen that these technologies build the initial version of the blockchain, which can also be said to be a blockchain It is the underlying technology of Bitcoin. In the three years from 2007 to 2009, Bitcoin was in the experimental stage with the participation of a very small number of people, and real commercial activities had not really begun.
2. "Geek" niche stage: The "Geek" here refers to people who are enthusiastic about Internet technology and who regard technological innovation as their fashion and life. The first Bitcoin exchange appeared on February 6, 2010. On May 22 of the same year, someone bought 2 burgers with 10,000 Bitcoins. On July 17 of the same year, the exchange Mt. Gox was established. This marks As Bitcoin officially flows into the market. Despite this, the only people who can truly understand and enter the market to participate in Bitcoin buying and selling are geeks who are passionate about Internet technology. They discuss Bitcoin technology on forums, mine Bitcoins on their computers, and then buy and sell Bitcoins on Mt. Gox. Today, these geeks have become billionaires.
3. Market brewing stage: At the beginning of 2013, the price of Bitcoin was US$13. However, on March 18 of the same year, the Cyprus government closed banks and the stock market due to the financial crisis, causing the price of Bitcoin to soar. In April, the highest price rose to US$266. . On August 20 of the same year, the German government confirmed the currency status of Bitcoin. On October 14, the Chinese Internet announced the opening of a Bitcoin payment channel. In November, the U.S. Senate hearing also clarified the legality of Bitcoin. On November 19, the price of Bitcoin It rose to $1,242, forming a new high. Despite this, the foundation for blockchain to enter the mainstream social economy is not yet available, and the surge in Bitcoin prices is only due to overly optimistic expectations. Containment of China’s banking system, collapse of Mt. Gox and moreIncidents caused the price of Bitcoin to continue to fall. At the beginning of 2015, the price of Bitcoin had fallen below 200 US dollars. From 2013 to the beginning of 2015, the public began to understand Bitcoin and blockchain.
4. Blockchain mainstream period: Britain left the EU on June 23, 2016, North Korea’s fifth nuclear test in September, Trump’s election in November and other events. The uncertainty of the world’s mainstream economy has led to risk aversion. Functional Bitcoin began to recover. The market demand was large and the increase in transaction volume caused the price of Bitcoin to soar from a maximum of 400 US dollars in 2016 to 20,000 US dollars in 2017. The wealth-making effect of Bitcoin and the transaction overflow caused by the congestion of the Bitcoin network It has led to the explosion of other series of virtual currencies, and various blockchain applications have also exploded.
