3. 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 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 physical economy.economy, and began 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 the theoretical basis and technical support for the large-scale application of blockchain, and the future world will also be transformed by it. 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.

4. 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!

5. Leading digital currency concept stocks

Digital currency is electronic currency that replaces traditional currency. It can be seen that digital currency and cryptocurrency are both digital currencies. Compared with traditional currency, digital currency has the characteristics of being invisible and intangible. It is not as convenient for government issuance and supervision as traditional currency. It circulates mainly among many virtual communities. This circulation is a breeding ground for crime. In order to solve this hidden danger, China has vigorously developed digital currency since 2019 to avoid its drawbacks and make digital currency serve trade, which can not only improve economic development, but also make digital currency more useful. So what are the leading digital currency concept stocks now? According to data from Oriental Fortune Network, as of Tuesday, July 20, 2021, the leading stocks in the digital currency sector are as follows:

National Technology (300077);

2. Hanwei Technology (300007);

3. Ren Zixing (300311);

4. Ziguang Guowei (002049);

5. Win when you win (30037);

6. North China (002987), etc.

Regulation of Digital Currency

Digital currencies issued by leading companies in digital currency concept stocks should be subject to regulation because during their development and growth process, they enter a period of growth according to the index. Without effective supervision, blockchain technology cannot be used reasonably. Therefore, the regulatory agency of the People’s Bank of China established a digital currency regulatory mechanism.

6. What is blockchain, and can blockchain be invested in?

What is blockchain, and can blockchain be invested in?

Blockchain Technology is an emerging concept after the introduction of the Internet concept. It mainly solves the information asymmetry in society and decentralized services. Give an example to explain what blockchain technology is:

Usually we deposit cash into the bank. Every time we withdraw money, the transfer must go through the bank system to complete. So if we use blockchain technology To solve this problem, then our money does not need to be placed in the bank. When transferring money to others, we only need to transmit data on the chain. The transfer record data will be recorded by the entire network, and the consumption path of the amount can be found at any time. , there is no need to go through any intermediary to complete the intermediate recording.

This is just one of the scenarios where blockchain technology is applied. At present, the payment industry, gaming industry, lottery gambling industry, etc. are the most widely used blockchain technology.

In the nascent stage of the development of blockchain technology, many investors will naturally see the development potential and prepare to invest in blockchain. So how to invest in blockchain? Everyone knows that with the emergence of blockchain technology, digital currency will be generated, and the circulation of digital currency will generate value. Ordinary people can invest in blockchain by purchasing digital currency. Common digital currencies include Bitcoin, Ethereum, Yuzi, etc. However, the risk is extremely high. The return is much higher than that of stock investment, but the risk is also several times higher. Therefore, when investing in blockchain, the choice of digital currency is also very important. For novice investors, it is recommended to choose mainstream currencies, such as Bitcoin, Ethereum and Ripple. Their value has been basically recognized, they have a consensus mechanism, and the price will not drop significantly. However, the corresponding blockchain technology is still the best. Ethereum.

For professional risk control investors, you can choose to invest in blockchain companies, taking a fancy to their long-term value and tokens. Nowadays, blockchain companies will issue coins, which are so-called digital currencies. However, their value is zero and they have no actual circulation significance. Therefore, if you choose to invest in a blockchain company, you still need to see clearly the content of the company's projects, whether they can be truly implemented, and how much potential they have for changing human life in the future.

7. What is the concept of blockchain

Concept: Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm.

The essence of the blockchain is a distributed public ledger. Anyone can verify this ledger, but no single user can control it. Participants in a blockchain system jointly maintain a ledger: it can only be modified according to strict rules and consensus.

The development of blockchain has gone through three stages:

1. Incubation period: 2009-2012, the economic form was dominated by Bitcoin and its industrial ecology.

2. Embryonic period: The period is from 2012 to 2015. Blockchain entered the public eye with Bitcoin, new wallet payment and remittance companies appeared, and the blockchain economy spread to the financial field. The underlying technology of blockchain continues to innovate. Blockchain technology is divorced from the Bitcoin system.

3. Development period: In 2016, industry applications began to be explored, and a large number of blockchain startups emerged. The popularity of ICO in 2017 brought unprecedented attention to blockchain.

(7) Is 300311 a blockchain? Extended reading:

Three characteristics of three blockchains:

1 , The core idea of ​​blockchain is decentralization: in the blockchain system, the rights and obligations between any nodes are equal, and all nodes have the ability to vote with computing power, thusIt is guaranteed that the recognized result is the result recognized by more than half of the nodes. Even if it suffers a severe hacker attack, as long as the number of nodes controlled by the hacker does not exceed half of the total number of global nodes, the system will still be able to operate normally and the data will not be tampered with.

2. The biggest disruption of blockchain lies in the establishment of credit: in theory, blockchain technology can make WeChat Pay and Alipay no longer valuable. The Economist made a vivid metaphor for blockchain: simply put, it is “a machine that creates trust.” Blockchain allows people to collaborate without trusting each other and without a neutral central authority. Combating counterfeit currency and financial fraud will no longer be needed in the future.

3. The collective maintenance of blockchain can reduce costs: In a centralized network system, the maintenance and operation of the system rely on the operation, maintenance and operation of platforms such as data centers, and costs cannot be omitted. Anyone can participate in the nodes of the blockchain. While participating in the recording, each node also verifies the correctness of the recording results of other nodes, which improves maintenance efficiency and reduces costs.

In one sentence, blockchain touches money, trust and power, which are the fundamental foundations on which human beings rely for survival.
