❶ What exactly is blockchain and can it make money

Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. . The so-called consensus mechanism is a mathematical algorithm that establishes trust and obtains rights and interests between different nodes in the blockchain system.

How to make money in the blockchain:

1. Earn commissions through promotion.

The blockchain approach is to first register an exchange account, generate your own invitation link, and then promote it. If someone registers the exchange through your link and generates transactions, you will get a commission.

2. Coin speculation.

Speculating in currencies is like speculating in stocks. Coin speculation is the lowest threshold way to make money in the blockchain.

3. Mining.

"Mining" in Bitcoin is the accounting process. This process requires grabbing, and if you grab the opportunity to bookkeeping rights, you will be rewarded, and the reward is Bitcoin. This behavior is "mining".

4. Develop wallet.

The wallet is the infrastructure of the blockchain, just like the "Alipay" or "WeChat Pay" of the blockchain.

Extended information:

1. Blockchain is an important concept of Bitcoin. It is essentially a decentralized database and serves as the bottom layer of Bitcoin. technology. The blockchain is a series of data blocks generated using cryptographic methods. Each data block contains information about a Bitcoin network transaction and is used to verify the validity of its information (anti-counterfeiting) and generate the next block.

2. Blockchain was born from Satoshi Nakamoto’s Bitcoin. Since 2009, various Bitcoin-like digital currencies have appeared, all based on public blockchains.

3. On January 20, 2016, the Digital Currency Seminar of the People’s Bank of China announced that it had achieved phased results in digital currency research. The meeting affirmed the value of digital currency in reducing the issuance of traditional currency and stated that the central bank is exploring the issuance of digital currency. The expression of the People’s Bank of China’s Digital Currency Seminar has greatly enhanced the confidence of the digital currency industry. This is the first time that the five central bank ministries and commissions have expressed a clear attitude towards digital currencies since they issued a notice on preventing Bitcoin risks on December 5, 2013.

❷ What are the applications of blockchain education

There are many directions for combining education with blockchain. Our country The "China Blockchain Technology and Application Development White Paper" and the European Commission's report "Blockchain in the Education Industry" both conducted preliminary discussions on the application model of blockchain in the field of education.
The application models of blockchain in the field of education mainly include:
Intelligent transactions create an educational Taobao platform based on smart contracts, build communities to achieve true "self-organizing" operation of online learning communities, and non-school educational institutions join Multiple topics in the market jointly participate in the formulation of educational content and the establishment of an accessible individual academic credit database.The global problem of fraudulent academic qualifications.
Online education branches are very broad, and the ecological structure applied to each branch is also different. Existing online platforms should seize opportunities for ecological optimization, not only in their own market segments, but also in achieving continuous optimization in the entire online education market.

The Xueshuo Innovation Blockchain Technology Workstation under Lianqiao Education Online is the only “blockchain technology workstation” approved by the “Smart Learning Workshop 2020- Xueshuo Innovation Workstation” carried out by the School Planning and Construction Development Center of the Ministry of Education of China.

❸ What are the prospects for the future development of blockchain

Shared from District View Network: In 2018, blockchain-linked AI has become the most popular technical term, and there are already more and more Technology companies have announced their entry into the blockchain market. On the Internet, companies such as Xunlei, Renren, Baofeng, and Tianya have all made blockchain-related actions. These companies have the same fate. They have all experienced prosperity, but after being impacted by the Internet entrepreneurship wave, they began to decline. Then they caught up with the hot spots of blockchain and began to try to counterattack.
Investment in the global blockchain industry is booming
According to the "In-depth Analysis Report on Business Model Innovation and Investment Opportunities in the Blockchain Industry" released by the Qianzhan Industry Research Institute, as of the end of April 2017, there were a total of 455 companies worldwide The blockchain company has received a cumulative financing amount of US$1.947 billion. Among them, the total investment and financing of U.S. blockchain-related companies is as high as 1.252 billion U.S. dollars, accounting for 64.3% of the global market; the total financing amount of Chinese blockchain emerging companies is approximately 114 million U.S. dollars, accounting for 5.86%, ranking second only to the United States in the world Second, it is growing rapidly.
The current overall survival status of the blockchain is good, with a survival rate of 87.25%. 47
of all the invested companies have been closed down, accounting for about 10.51%, and another 10 companies have been acquired. Due to changes in the competitive landscape of the Bitcoin market, some companies have been forced to close down. At the same time, some companies in the currency circle have gradually transformed into chain companies
Exploration at the national level has also begun. On March 23, the Department of Information Technology and Software Services of the Ministry of Industry and Information Technology announced that it would study and explore the application of blockchain in the industrial field. Previously, the Ministry of Industry and Information Technology stated that it was preparing to establish a national blockchain and distributed accounting technology standardization technical committee to explore the formation of a complete blockchain standard system to better serve the development of the blockchain technology industry.

❹ What is the nature of the China Blockchain Technology and Application White Paper?

This is a research report document and does not have any legal effect, it is just a suggestion.
The founding meeting of the China Blockchain Technology and Industry Development Forum and the first developer conference were held on October 18. The meeting released the "China Blockchain Technology and Application Development White Paper".
《白Paper" summarizes the current status and trends of blockchain development at home and abroad, analyzes the technical applications of multiple application scenarios including finance, supply chain, culture and entertainment, intelligent manufacturing, social welfare, education and employment, etc., and points out the core of blockchain Technical path and future blockchain technology standardization direction and process. (Reprinted from China Business Network)
The scope of blockchain application is theoretically very wide, but now blockchain is still in an early stage of development. Ethereum is mainly a smart contract platform; DECENT is a distributed content publishing platform.

❺ What are the application fields of blockchain technology?

Application fields: financial field, Internet of Things and logistics field, public service field, digital copyright field, insurance field, and public welfare field.

Blockchain can also be naturally combined in the Internet of Things and logistics fields. Through blockchain, logistics costs can be reduced, the production and delivery process of items can be traced, and the efficiency of supply chain management can be improved. This field is considered a promising application direction of blockchain.

Blockchain is closely related to people’s production and life in the fields of public management, energy, transportation, etc. However, the centralized nature of these fields also brings some problems, which can be transformed with blockchain.

❼ Blockchain Graduation Project Proposal

Background of the project research:

With the development of modern technology and information industry, at this stage, the fourth The second industrial revolution is beginning to take shape, and the world is about to enter a technological era centered on new technologies such as the Internet and artificial intelligence. At the same time, blockchain technology has emerged as the times require and has become a hot topic of concern to many international governments and industries. Blockchain technology has been regarded as the core technology with the greatest potential to trigger the fifth round of disruptive revolution after steam engines, electricity, information and Internet technology. In the past 10 years, with the strong support of the government and policies, the development situation of my country's philanthropy has been relatively optimistic. However, as the scale of charity continues to develop and expand, my country's public welfare undertakings have gradually revealed some shortcomings. The biggest problems existing in traditional public welfare undertakings are insufficient credibility, imperfect internal management of charitable organizations, and high costs. However, many Internet public welfare service companies are currently actively using the new technology of blockchain to solve this problem. Blockchain technology has the characteristics of decentralization, information traceability and non-tampering, openness and transparency, and smart contracts. It can make up for the shortcomings of traditional public welfare undertakings such as opaque information and low management efficiency. Blockchain technology will enter public welfare undertakings and will Bring new development opportunities to the charity industry.

The main content of the research: This topic mainly includes the following three aspects:

[if !supportLists] 1. [endif] Combination of blockchain technology and public welfare Problems that arise and solved.

[if !supportLists] 2. [endif] Make a public welfare query webpage based on blockchain technology

[if !supportLists] 3. [endif] The query system Application issues and explanations

Purpose of the research:

As the scale of my country’s public welfare continues to develop and expand, our shortcomings have also been exposed, including lack of credibility, and charitable organizations There is a lack of management, and the use of blockchain technology can solve this problem. This technology will track and store data and behaviors throughout the donation process, realize the complete disclosure of the public welfare chain, enable donors to effectively supervise, avoid shortcomings such as low efficiency and clear fund flows, control risks for public welfare projects, and improve Credibility and transparency of public welfare projects promote the development and progress of public welfare projects and enhance trust between people. According to the attributes and characteristics of the blockchain system, public welfare enterprises can implement full control of data and behavior in the public welfare process.Cycle tracking, evidence storage and auditing enable all parties involved in public welfare projects to track and effectively supervise the project, avoiding the shortcomings of artificially reduced efficiency in public welfare projects, thereby providing public welfare projects with rational methods to control risks and judge effects, and improve The transparency of public welfare undertakings promotes the development of public welfare.

Significance of the project research: This project intends to develop an open and transparent system for tracking public welfare donations based on blockchain technology and combined with the actual development of public welfare undertakings in my country. Through in-depth analysis of blockchain technology and charity business, we found that blockchain technology has natural advantages in solving the problem of public welfare transparency. Blockchain technology can be understood as a distributed accounting method that can record all transaction information and ensure that it cannot be tampered with. This determines that wherever justice, fairness, and integrity are required, blockchain has great technology. Room to play. At the same time, the addition of smart contracts directly solves the business problem of earmarked funds.

Eventually, trust between citizens will be enhanced, donation channels will be accelerated, and the development of social donations will be promoted

❽ What blockchain technology cannot do

What blockchain technology cannot do
"China Blockchain" issued by the Ministry of Industry and Information Technology "White Paper on Chain Technology and Application Development" (2016) points out that blockchain is mainly used in the Internet of Things, intelligent manufacturing, supply chain management, digital asset transactions and other fields, and provides a basis for the development of new generation information technologies such as cloud computing, big data, and mobile Internet. It has brought new opportunities, and may also have the ability to trigger a new round of technological innovation and industrial changes. Open source communities, industry alliances, key enterprises, start-up companies, investment institutions, financial institutions, and regulatorsInstitutions are participants in the development of blockchain technology and applications.
As we all know, blockchain technology was first used in the financial field. The identity of the blockchain is a decentralized distributed ledger database. Its information transparency, data storage security, and transaction process without any intermediary platform play particularly well in this field, and are particularly useful for supervision, anti-counterfeiting, and improving processing efficiency. ....Blockchain technology seems to be full of endless possibilities.

In my country, financial companies, Internet companies, IT companies and manufacturing companies are also actively investing in the research and development and application promotion of blockchain technology, which has given rise to rapid development momentum of blockchain. For example, SF Express has been developing and deploying services such as blockchain pharmaceutical traceability and drone pharmaceutical transportation in the field of pharmaceutical logistics. Recently, it has officially implemented blockchain pharmaceutical traceability.
However, no matter how great the role of blockchain is imagined and described, when facing the emergence of a new event or concept, we must pay more attention to all aspects of things. You must know that the concept of blockchain was born with the emergence of Bitcoin in 2009, and it was not until around the beginning of 2018 that blockchain gradually became known in China, and then large companies such as Alibaba, Internet, and Xunlei joined in. Among them, nine years is a long enough time to develop businesses that can be supported by blockchain technology, but it seemed to explode suddenly in 2018, even without warning. Therefore, investors should be vigilant. It is also necessary to carefully consider whether to invest or not when my country's domestic blockchain technology has just started and is immature, taking into account my country's national conditions, social development level and other factors.
What blockchain technology cannot do is first created by immature technology. At least in China, when blockchain has just emerged, the technical platform is not as good as abroad, and the business supported by the technology should not be widely launched. Technical personnel applying blockchain must be patient, learn more from advanced experience, and work in detail. .
The second is that blockchain technology cannot regulate the fair, equitable and effective operation of the blockchain market. For example, as soon as blockchain technology entered our country, there were many scam companies using its name to collect funds and make money. It was difficult for the public to judge the difference between "technological innovation" and "fund-raising innovation", so they were easily deceived. Therefore, when it comes to blockchain, if we want it to be technically autonomous and controllable and adapt to the requirements of a variety of scenarios, it will be decided by time; if we want it to be autonomous and controllable in terms of value, we need to be able to use it to its full potential. Its greatest value is determined by the supervision of government organizations, regulatory authorities, experts, etc.
Even though the possibilities of blockchain technology are infinite, the industries and markets under it are frequently chaotic. Without listing them one by one, there are still too few places that blockchain can "manage". In terms of how to use blocks correctly, When it comes to blockchain technology doing what it is supposed to do, people's hearts must not be confused first, and this shows that the whole society has a long way to go.
