What is the blockchain and can it be invested in?

District Blockchain technology is an emerging concept after the introduction of the Internet concept. It mainly solves the information asymmetry in society and provides 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.

II How much change can blockchain technology bring to stock trading?

The changes are as follows:
1. Blockchain technology can realize automated transaction settlement on exchanges, bypassing Through a third party, it improves transaction speed, reduces costs, and reduces operational risks and human errors.
2. At present, blockchain technology is mainly used for post-trade clearing services and equity transaction management in the over-the-counter market, rather than the mainstream trading market on the market. The reason is that blockchain technology requires a large amount of storage space and a long confirmation time, coupled with the limitation of transaction speed, it is not suitable for centralized on-site transactions.
3. Blockchain is suitable for securities registration because of its confidentiality and immutable characteristics., and can reduce registration time.
4. Blockchain technology is a double-edged sword for exchanges. On the one hand, it helps exchanges reduce operating costs and risks. On the other hand, it also reduces exchanges’ income from clearing (settlement fees decrease , the shortening of the settlement cycle will reduce the interest income of custodian banks and settlement companies). Therefore, for exchanges, after using blockchain, they need to develop new data services to make up for their profits.
Of course, blockchain will also have some positive impacts on traditional industries. Blockchain has already had a positive impact on crowdfunding, banking, and tea collections. Puyin Group launched Puyin, a tea-based digital currency.

Ⅲ What exactly is blockchain? How do ordinary people make money in blockchain?

The popularity of blockchain has caught the public off guard. Nowadays, no one knows about blockchain, but many people do not have a clear understanding of the definition of blockchain.

So, what exactly is blockchain?

Regarding blockchain and Bitcoin, most people have this misunderstanding: Bitcoin is blockchain.

In fact, Bitcoin and blockchain are not the same thing. Blockchain is the underlying technology of Bitcoin, but the first usage scenario after the birth of blockchain is Bitcoin.

I will explain to you what Bitcoin is and what blockchain is. Please move your bench quickly!

What is Bitcoin?

Bitcoin is a digital currency, a peer-to-peer encrypted digital currency. It is not a tangible paper currency such as RMB or US dollars. It is generated by computers through specific mathematical calculations. Also stored in the computer.

Because Bitcoin is just a string of data in a computer, it is also called a "virtual currency" compared to paper currency. To put it simply, you can understand that Bitcoin is just a string of numbers with cash value, similar to Q coins. In other words, Bitcoin has no actual value. Its current value is supported by the faith of currency speculators. If the faith is gone, the value of Bitcoin will collapse.

Bitcoin is magical, what is its magic?

If you want to get Bitcoin, in addition to buying it, you can also mine it. The original Bitcoin is mined!

1) Mining

The first thing that comes to mind for many people is the image of a coal mine:

Mine, absenteeism, dust , black coal, large trucks.

Bitcoin mines are not like this. They only need electricity, network cables, and computers. However, mining this mine is a technical job, and it tests the performance of the computer's CPU and GPU.

2) Transaction

How does a Bitcoin transaction proceed?

Each user has a unique address, which is the Bitcoin "wallet". For every transaction, for example: A pays B a Bitcoin, a Weibo post will be posted publicly in the system saying: "I gave B a Bitcoin @B". These records will be kept as evidence at every terminal of the system. on the chain.

If A wants to go back on his word and tamper with Bitcoin’s transaction history, then every terminal record on the network must be modified. However, this is not easy, because only A whose computing power exceeds the sum of the computing power of all nodes in the system can tamper with transaction records. Obviously, this is unrealistic.

In the transaction process, Bitcoin uses a decentralized accounting method, which is also blockchain technology. Simply put, blockchain is a decentralized distributed ledger database.

What is blockchain?

The blockchain was created along with Bitcoin. During the formation of Bitcoin, blocks were storage units one by one, recording the communication information of each block node. Blocks are very similar to For database records, every time data is written, a block is created. With the expansion of information exchange, one block continues with another, and the result is called a blockchain.

Blockchain is a distributed ledger technology. Everyone participates in accounting, and everyone has a copy of the ledger information. This account book is not easy to forge and is traceable.

For example:

On a certain day of a certain year, Lao Wang lent Xiao Wang 10,000 yuan. Lao Wang told everyone around him the news , the transfer records were posted on WeChat Moments, and everyone helped them testify to the existence of this transaction.

Lao Wang and Xiao Wang are two nodes. These two nodes generate transaction time, location, person and other information, and they are packaged to form a "block". Lao Wang’s friends are also nodes. These nodes jointly record the transaction status and details (blocks) of the two nodes Lao Wang and Xiao Wang. These blocks are connected to form a chain, forming a decentralized database.

In the past, only both parties knew when Lao Wang and Xiao Wang borrowed money. This was the centralized accounting model. But now everyone knows it and records it in their own ledgers. This is the decentralized accounting model. model.

When one day, Xiao Wang regrets that he did not borrow the money, everyone around him will know their transaction information, so Xiao Wang will not be able to deny it. This is the blockchain Information sharing cannot be tampered with.

How do ordinary people make money by participating in the blockchain?

I have summarized several methods suitable for ordinary people to make money during the blockchain bonus period.

1. Direct investmentInvest in blockchain: Buy coins or buy some blockchain stocks, but the currency circle is risky, so you must be cautious when buying, and there are many blockchain stocks now, but the stock market is risky, so you need to be cautious when investing.

2. Make blockchain self-media: run a WeChat public account or Toutiao account, write articles about blockchain and publish them on it. If you are good, you can also get some good profits.

3. Participate in technology development: In fact, it is very simple, it is to participate in the process of blockchain development. However, this method requires high technical threshold.

4. Blockchain training: Companies that can provide blockchain technology training or knowledge training.

That’s all the relevant knowledge about what blockchain is, I hope it can bring you some help.

IV Application aspects of blockchain

The main application scope of blockchain includes: digital currency, transaction settlement of financial assets, digital government affairs, certificate deposit and anti-counterfeiting data services and other fields. Blockchain is a database technology that links data blocks in an orderly manner. Each block is responsible for recording a file data and encrypting it to ensure that the data cannot be modified or forged.

Blockchain is essentially a distributed database system that uses cryptography technology for multi-party participation, joint maintenance, and continuous growth. It is also called a distributed shared ledger. Each page in the shared ledger is a block, and each block is filled with transaction records. The anonymity, decentralization, openness, transparency, and non-tamperability of blockchain technology make it highly favored by enterprises and has gained More extensive application attempts.

Blockchain application scope 1. Financial field

Blockchain can provide a trust mechanism and has the potential to change the financial infrastructure. Various financial assets such as equity, bonds, bills, warehouse receipts, fund shares, etc. It can be integrated into the blockchain technology system and become a digital asset on the chain, which can be stored, transferred and traded on the blockchain.

The decentralization of blockchain technology can reduce transaction costs and make financial transactions more convenient, intuitive and secure. The combination of blockchain technology and the financial industry will inevitably create more and more business models, service scenarios, business processes and financial products, thereby bringing more impact to the development of financial markets, financial institutions, financial services and financial formats. . With the improvement of blockchain technology and the combination of blockchain technology with other financial technologies, blockchain technology will gradually adapt to the application of large-scale financial scenarios.

2. Public service field

Traditional public services rely on limited data dimensions, and the information obtained may not be comprehensive enough and have a certain lag. The non-tamperable nature of the blockchain makes the digital certification on the chain highly credible. It can be used to establish new authentication mechanisms in the fields of property rights, notarization and public welfare, and improve the management level of public services.

Relevant information in the public welfare process, such as donation projects, fundraising details, fund flows, recipient feedback, etc., can be stored on the blockchain.Under the premise of protecting the privacy of project participants and other relevant laws and regulations, the information will be publicly disclosed conditionally to facilitate public and social supervision.

3. Information security field

Using the traceability and non-tampering characteristics of blockchain, we can ensure the authenticity of data sources and ensure the non-forgery of data. Blockchain technology will fundamentally change information Security issues of the propagation path.

Blockchain is reflected in the following three points in the field of information security:

User identity authentication protects data integrity and effectively prevents DDoS attacks

The distributed storage architecture of blockchain will make Hackers are at a loss as to what to do. Some companies have begun to develop a distributed Internet domain name system based on blockchain to eliminate the root cause of the current DNS registration shortcomings and make the network system cleaner and more transparent.

4. Internet of Things field

Blockchain + Internet of Things can allow each device on the Internet of Things to operate independently, and the information generated by the entire network can be protected through smart contracts in the blockchain.

Security: Traditional IoT devices are highly vulnerable to attacks, data loss and maintenance costs are high. Typical information security risk issues for IoT devices include low firmware versions, lack of security patches, permission loopholes, too many device network ports, and unencrypted information transmission. The blockchain's consensus mechanism for network-wide node verification, asymmetric encryption technology and distributed data storage will significantly reduce the risk of hacker attacks.

Trustability: The traditional Internet of Things is managed and controlled by a centralized cloud server. Due to the security of the device and the opacity of the centralized server, it is difficult to effectively protect user privacy data. The blockchain is a distributed account book. Each block is interconnected and has its own independent working ability, ensuring that the information on the chain will not be tampered with at will. Distributed ledgers can therefore provide trust, ownership records, transparency and communication support for the Internet of Things.

Effectiveness: Limited by cloud services and maintenance costs, the Internet of Things is difficult to achieve large-scale commercial use. The traditional Internet of Things realizes communication between things through centralized cloud servers. The disadvantage of this model is that as the number of access devices increases, the server faces more load, requiring enterprises to invest a lot of money to maintain the normal operation of the IoT system.

Blockchain technology can directly realize point-to-point transactions, omitting the labor expenditure of other intermediaries or personnel, which can effectively reduce the costs incurred by third-party services and maximize benefits.

5. Supply chain field

The supply chain consists of many participating entities, with a large amount of interaction and collaboration. Information is discretely stored in their own systems, lacking transparency. The lack of smooth information makes it difficult for various participating entities to accurately understand the real-time status and existing problems of related matters, affecting the collaborative efficiency of the supply chain. When disputes arise between parties, it is time-consuming and laborious to provide evidence and pursue accountability.

Blockchain can make data open and transparent among various entities, thereby forming a complete, smooth, and non-tamperable information flow throughout the entire supply chain. This can ensure that all entities promptly discover when the supply chain system is runningproblems and find targeted solutions to improve the overall efficiency of supply chain management.

6. Automotive Industry

Last year announced a partnership using blockchain to build a proof of concept to streamline the car rental process and build it into a “click, sign up, and drive” process. Future customers choose what they want The rented car enters the public ledger of the blockchain; then, sitting in the driver's seat, the customer signs the rental agreement and insurance policy, and the blockchain updates the information simultaneously. This is not an imagination, for car sales and car registration Said, this type of process may also develop into reality.

7. Stock Trading

For many years, many companies have worked to make the process of buying, selling, and trading stocks easy. Emerging Blockchain Chain startups believe that blockchain technology can make this process more secure and automated than any previous solution. At the same time, blockchain startup Chain is working with Nasdaq to enable private companies through blockchain. Equity transfer

8. Government management

Government information, project bidding and other information are open and transparent. Government work is usually subject to public attention and supervision. Since blockchain technology can ensure the transparency and immutability of information, it is very important to the government. The implementation of transparent management plays a great role. There is a certain degree of information opacity in government project bidding, and enterprises also have the risk of information leakage during the sealed bidding process. Blockchain can ensure that bidding information cannot be tampered with and can ensure the transparency of information nature, forming a common trust among competitors who do not trust each other. It can also arrange subsequent smart contracts through the blockchain to ensure the construction progress of the project and prevent the growth of corruption to a certain extent.

There are many more applications of blockchain technology, and this is just a fulcrum of blockchain applications. In the future, blockchain technology will be applied everywhere

IV Brief description of blockchain finance How does the rich securities fund business develop? Traditional financial institutions such as banks, securities, and insurance companies have developed to this day. They are huge in size, have solid models, and are highly centralized, which has led to the formation of information barriers between various institutions and reduced communication efficiency. , the cost has increased significantly. The information Internet brought about by the first digital revolution has given birth to an emerging Internet financial system, which is committed to broadening the circulation channels of funds and realizing point-to-point communication between supply and demand. The current mature information Internet only realizes the digital transmission of information. , and blockchain can build a value Internet that digitally transfers value based on its decentralization, non-tampering, openness and transparency, privacy protection and other characteristics, leading the second digital revolution and opening a new chapter in Internet finance.

VI How to make money in the blockchain and what are the economic prospects

MLM.

VII How about blockchain digital currency investment? Does anyone have any advice?

1. Use spare money to invest
Be sure to use spare money to invest, and never use leverage (in fact, this is the basic common sense for ordinary people to invest). Compared with stocks, funds, etc., digital currency transactions are more frequent and convenient (7*24 hours), so people are more likely to be impulsive. Moreover, the bull and bear markets of digital currency often come suddenly, which may bring unnecessary trouble to life if you don’t have spare money.
2. Moving bricks
If you think "long-term investment" such as digital currency is too slow and want to make quick money, then "moving bricks" may be more suitable for you.
Buying is to use the price difference of the same digital currency between exchanges to buy and sell, and make profits from it. For example, if the price of X coin is 10 yuan on exchange A and 15 yuan on exchange B, and the price of coin Y is 10 yuan on exchange B and 14 yuan on exchange C, then you can buy it on exchange A. For X currency, transfer the currency to Exchange B and sell it; at the same time, buy Y currency on Exchange B, then transfer it to Exchange C and sell it to earn the price difference.
This way of making money does not require a deep understanding of blockchain knowledge. What is required is speed, courage, time, and energy. If you encounter big fluctuations, the profits will be quite generous. For example, a netizen recently purchased EOS from China and then transferred it to an exchange in South Korea to sell it, making a profit of more than 80,000 yuan in one night.
Of course, "moving bricks" also requires you to have a certain amount of capital reserves (usually around tens of thousands of yuan), otherwise the money earned from the price difference alone will not be enough for transaction fees and currency withdrawal fees.
3. Digital currency investment homework
Before investing in a project, you must do enough homework and understand the future development prospects of the project in detail through various channels, including the profit model, valuation space, and project team. Understand it carefully and deeply. It would be terrible to invest money without knowing what the project is about.
Blockchain is an emerging industry. It is currently in a mixed situation. The quality of the personnel is also uneven. Naturally, there are also scammers who use ICO to make money. When we invest, we must be careful and don’t be fooled by a few people. The beautiful PPT has been deceived. You must keep your eyes open and seek verification from various sources. Even if you have a lot of money, don't be fooled.
As for how to identify a scam, you must rely on yourself. What is certain is that those projects that promise high returns must be scams, because any project has the possibility of failure. In fact, as long as you do multiple verifications , it is not difficult to identify a scam.
4. Psychological Warfare of Digital Currency Investment
1. Buy and leave. This is a very important point. After buying, many people will pay attention to the rise and fall of the price. In severe cases, their mood will also follow the price. It changes with the rise and fall of the price, and even the IQ will change with the rise and fall of the price, so there will be a situation of chasing the rise and killing the fall. When the price starts to soar, I regret buying too little, so I add a position, and the price suddenly After a callback, fear appeared in my heart again, and I thought it would be better to throw it away, so my whole person changed accordingly, and my quality of life was seriously affected.
How to prevent the above situation? The answer is to set an expected return or holding time in your mind before investing. This is actually extremely important. If you decide to hold it for one year, no matter how the price changes,Don't worry about it, and think about it a year later. If you think it's okay to increase by five or ten times, then sell it when it reaches your psychological price.
2. Never take advantage of it. The blockchain industry has just emerged and the market is still blank, so there will be many good projects related to it. We must not invest all our funds in one project, even if this project It’s not good to be very good. You must know that any project may not be successful, so you must learn to diversify your investments. Diversified investments also mean diversifying risks. The most important principle in the investment field is to consider risks first and then returns. Risks are always ours. The first factor to consider.
In addition to diversifying funds into different projects, we should also pay attention to the fact that the proportion of funds used for investment must be allocated reasonably. Never use all of it for investment, because once you use too much money for investment , when prices fall, it will definitely affect your life, and in turn affect your decision-making. Then you are likely to sell your shares during the bear market. If you cannot survive the bear market, you will naturally not be eligible to enjoy the benefits of the bull market. Gained.

Ⅷ Is blockchain useful? What is the impact and prospects of blockchain?

I believe everyone is no longer unfamiliar with the emerging technology of blockchain, because this is the current The most popular topic of Jiao Chun, many big guys in different industries are analyzing its role and prospects. Today we also do some research on the blockchain. Is the blockchain useful and what is the impact of the blockchain? and prospect analysis, I hope it can help everyone.
Is blockchain useful?
1. Banking: As a digital, secure and interference-proof account, blockchain realizes the core function of the banking industry: a safe storage and transfer center of value. In other words, in the next few years, a wave of companies based on blockchain technology may affect the banking industry.
2. Payment and transfer: Blockchain technology can avoid complicated systems and create a more direct payment process between the payer and the payee. Whether it is a domestic transfer or a cross-border transfer, this method has its advantages. Low price, fast, and no intermediate handling fees.
3. Network security: Although the blockchain system is public, its verification, sending and other data exchange processes use advanced encryption technology. This technology not only ensures the correct source of data, but also ensures that the data is not intercepted during the process. If blockchain technology is more widely used, the probability of being attacked by hackers may also decrease, so people believe that blockchain systems are more stable than traditional systems. One of the reasons why blockchain systems can reduce traditional network security risks is that they eliminate the need for middlemen.
4. Election: Everyone's vote "can never be modified or deleted by us - programmers, school administrators or students."
5. Smart contract: Smart contracts are actually on another object. A computer program that performs functions on the go. Like ordinary computer programs, smart contracts are also an "if-then" function, but blockchain technology realizes these "if-then" functions."Contracts" are automatically filled in without human intervention. Such contracts may eventually replace the core business of the legal merger industry, which is the business of drafting and managing contracts in the commercial and civil fields.
6. Stock trading: For many years, various Companies are looking for ways to simplify the process of buying, selling and trading stocks, and emerging blockchain technology startups believe they can go beyond the past, automating the entire process and improving security and efficiency.
What is the impact of blockchain and Prospects?
1. The dual impact of wealth and risk:
The difference between blockchain technology and traditional Internet technology is that it chooses the high-risk financial industry as its entry point, but the financial field is a It is an area full of many obstacles. Such direct entry has a dual impact: on the one hand, it can bring wealth effects to entrepreneurs relatively quickly; on the other hand, various risks will also come directly and violently.
2. Improvement Efficiency and cost reduction:
For physical finance, blockchain can maintain fidelity in the process of transmitting information, such as personal credit information and other data, thereby avoiding many transaction costs and improving efficiency on a large scale. This is why it The positive significance brought by it.
3. Control financial risks early and small:
Blockchain is cooperating with the innovation of digital currency to prevent over-insurance in the insurance industry and over-lending in bank mutual funds loans. , the integration of supply chain finance, and the promotion of electronic identity recognition, etc., are applicable to many industries and fields. In terms of financial security, many companies have also cooperated with regulatory authorities to build regulatory technology systems to help regulatory authorities conduct risk management of Internet financial companies. Monitor and warn early to control financial risks.
4. The owner of the data should be the user himself:
Blockchain is a technology worthy of attention, and it can be found in one’s own business and investment Related layout. Bitcoin and various other electronic currencies are applications based on blockchain technology. They have certain currency functions and have certain use value, but the main problem now is the difference between use value and transaction price. The gap is too big. ICO is a financing business model.
5. The darkest stage contains the most opportunities:
The darkest stage often contains the most opportunities, and the application scope of blockchain is far away Not only currency and finance, for example, big data can be applied to the entire medical and health field in the future. If medical records and diagnosis data are shared to all different medical systems through the big data blockchain, the efficiency of treating diseases and saving lives can be greatly improved.
Editor He believes that the correct development prospect of blockchain is to "talk less about financial innovation, pay more attention to financial security, pay more attention to inclusive finance, and do more medical, health, and environmental protection."
The above is the block brought to you by the editor Is blockchain useful? What is the impact and prospects of blockchain? All content.
