『一』How to make money with blockchain and what are its economic prospects

Blockchain suddenly became popular in 2017, and it also blew up my circle of friends. Some people say that the current blockchain is the early stage of the Internet in 2000. So how does the blockchain make money? What are the economic prospects?

In fact, the essence of blockchain is a protocol: a trust agreement through value transmission; it is also a decentralized database: the security and reliability of data are maintained through collective protocols through decentralization and encryption algorithms.

Bitcoin is a digital currency because it has the functions of exchange medium, value storage, circulation, etc., and the blockchain is the time-stamped Bitcoin.

The future of blockchain still has a long way to go, because it requires the support and promotion of governments of various countries.

Personal public account: Wu Liting Anita, financial management in both places, focusing on personal growth!

『二』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 It is the most popular topic at the moment, and many big guys in different industries are analyzing its role and prospects. Today we also do some research on blockchain. Is the blockchain useful? and what are the benefits of blockchain? I hope this analysis of the impact and prospects 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 think 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 enables the automatic filling of these "contracts" without manual intervention. Such contracts may eventually replace the core business of the legal merger industry, namely in commercial and civil matters.Domain drafting and managing contracts.
6. Stock trading: For many years, companies have been trying to simplify the process of buying, selling and trading stocks. Emerging blockchain technology startups believe they can go beyond the past, automating the entire process, improving security and efficiency.
What impact and prospects does blockchain have?
1. The dual impact of bringing wealth and risk:
The difference between blockchain technology and traditional Internet technology is that it chooses the high-risk financial industry as the entry point, but the financial field is full of Areas with 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. Improve efficiency and reduce costs:
For physical finance, blockchain can maintain the fidelity in the process of transmitting information, such as personal credit information and other data, thereby avoiding many transaction costs and enabling large-scale Improve efficiency, this is the positive meaning it brings.
3. Control financial risks early and small:
Blockchain is cooperating with the innovation of digital currency, preventing over-insurance in the insurance industry, over-lending in bank mutual funds loans, and the integration of supply chain finance. , promote electronic identity recognition, etc., 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 monitor and provide early warning for the risks of Internet financial companies, so as to control financial risks early and at an early stage.
4. The owner of the data should be the user himself:
Blockchain is a technology worthy of attention, and it has relevant layouts in its own business and investment. Bitcoin and other electronic currencies are applications based on blockchain technology. They have certain currency functions and have certain use value. However, the main problem now is that the gap between the use value and the transaction price 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. The application of blockchain is far more than just monetary and financial. For example, big data can be applied to the entire medical industry in the future. health field. If medical records and diagnosis data are shared to all different medical systems through big data blockchain, the efficiency of treating diseases and saving lives can be greatly improved.
The editor believes that the correct development prospect of blockchain is to "talk less about financial innovation, focus more on financial security, focus more on inclusive finance, and do more on medical care, health, and environmental protection."
The above is the blockchain brought to you by the editor. Is it useful? What impact and prospects does blockchain have? all content.

『三』The future prospects of blockchain e-commerce

This development model has good prospects.
Blockchain e-commerce is widely used in the economic field. Blockchain technology has strong practical significance in cultivating new drivers of economic growth, building an honest society, improving management technology, and alleviating financing difficulties for small and medium-sized enterprises.
Blockchain e-commerce has been widely used in many different fields., such as financial services, Internet of Things and supply chain management. It has the characteristics of decentralization, immutability and high security.

『四』Blockchain technology will change these 18 major industries in the future

Blockchain technology will change these 18 major industries in the future
Since the birth of the Internet, information dissemination has Costs have been greatly reduced, information dissemination efficiency has been rapidly improved, and social productivity has been liberated as never before. It is no exaggeration to say that the Internet has changed the entire pattern of human society.
However, while enjoying the many conveniences brought by the Internet, we have to admit that the Internet still has many flaws, especially in terms of security and mutual trust. The birth of blockchain technology has brought a new dawn to solve the problems existing in the Internet society.
Because blockchain technology is open and transparent, difficult to tamper with, and does not rely on intermediaries, blockchain can achieve safe, efficient, and low-cost value transmission. People are expected to build an Internet for value transmission based on blockchain to further promote the liberation of social productivity.
At the same time, just as "every new technology appears will change or even subvert many industries," in the future blockchain will change these 18 major industries!

1. Banking Industry
The application of blockchain technology in the financial field will change the transaction process and record keeping methods, significantly reduce transaction costs, and significantly improve efficiency.
2. Cybersecurity
Although blockchain is not a panacea to fix all Internet problems, it can be a powerful tool for experts and engineers, especially systems with single points of failure and centralized vulnerabilities.
3. Supply chain management
The supply chain is a complex functional network chain structure composed of suppliers, manufacturers, distributors, retailers, and users. In this chain, capital flow, information flow, and physical flow operate interactively, making coordination extremely difficult. The traditional coordination mechanism that relies on a single "chain owner" has encountered bottlenecks. The "decentralized" model of blockchain provides rich imagination for solving this problem.
4. Prediction field
The prediction market needs a platform that is decentralized, open and transparent, and more adaptable to global user participation to change the status quo, and this naturally matches the characteristics of the blockchain. Whether from sports betting to stocks to elections, these technologies allow for decentralized betting and observation.
5. Network and Internet of Things
The idea of ​​applying blockchain technology to the Internet of Things (IoT) has been around for some time. In fact, blockchain technology looks to be a suitable solution for at least three aspects of IoT: big data management, security and transparency, and micro-transactions based on the exchange of services between interconnected smart devices. Comes in convenience.
6. Insurance industry
The power of technology is making the insurance industry return to its essence: linking objects, regaining trust, and sharing. In other words, the law of large numbers in the traditional insurance industry may change due to technology,Technology and links encounter more uncertainties and create new possibilities.
7. Sharing Economy
Blockchain is inherently decentralized, which is highly consistent with the purpose of the sharing economy. The "Tencent Blockchain Solution White Paper" shows that Tencent is applying smart contracts to bicycle rental, house sharing and other fields. If this smart contract is applied to today's popular bicycle sharing field, it may bring new changes to the entire industry.
8. Cloud Storage
Blockchain technology can support distributed storage of encrypted data and is the core of collaborative cloud storage.
9. Charity industry
For charity, the openness and transparency brought by blockchain technology can ensure that donors can clearly understand the flow of their funds and can query it; the non-tampering feature can also ensure that financial Information cannot be tampered with; anonymity also protects donor privacy.
10. Voting
Blockchain technology can be applied to voter registration, identity confirmation, and electronic statistics to ensure that only legitimate votes are recorded and that votes will not be tampered with or removed. Create an immutable, publicly visible ledger of voting records to make elections fairer and more democratic.
11. Government Management
Government services are one of the most direct and significant application areas of blockchain technology. Information exchange across agencies will effectively improve government efficiency.
12. Public welfare industry
Internet culture itself has the genes of equality, openness, and mutual assistance, which is very consistent with the characteristics of public welfare.
13. Medical industry
The medical industry currently still relies on old systems and lacks ways to store data securely. Blockchain can be widely used in medical and health information sharing, medical process transparency, and medical accident liability traceability.
14. Energy Management
In order for the Energy Internet to be successfully implemented, various information interactions, smart grid control and scheduling, and coordinated control of distributed power sources are all obstacles that must be overcome, and blockchain Technology is trying to solve these problems.
15. Music Copyright
The importance of music copyright is self-evident to online music platforms. Having more copyrights means that it can capture more users, and the platform can therefore obtain better Development opportunities.
16. Retail industry
When we shop, we need to trust the store’s retail system. Decentralized blockchain can make retail different, as buyers and sellers can connect directly without middlemen and fees.
17. Real Estate Industry
Blockchain technology can change the way the real estate market operates. It can merge many complex processes and cases that real estate companies usually deal with, speed up transaction processes, reduce fraud, and provide benefits for everyone. Participants provide more transparent and secure transactions.
18. Your industry
If your industry deals with data or any trading system, it is very likely to be changed by the blockchain. This is an openingA field full of opportunities.
Of course, as an emerging technology, the application of blockchain still faces many challenges. More blockchain technology companies like Matrix are needed to overcome the difficulties in practical application of blockchain and promote blockchain technology. The widespread application and development of chains.

『Wu』How to introduce the blockchain in 3 minutes in a simple and easy-to-understand manner, and what its commercial value will be in the future

There is a real joke, an engineer from Ant Financial, He wrote a blind date resume, and the job description in it was "code farmer", but no one clicked it for a long time. Later, he changed his work experience to "blockchain" and received 381 love letters at once.

From workers in high-tech industries to square dancing aunties, it seems that everyone is participating in the blockchain carnival. So what exactly is the seemingly mysterious blockchain? After reading the following content, you will have completed the journey from beginner to beginner.

1. What is blockchain?

To put it bluntly, the blockchain is "everyone keeps accounts together." Any database needs a big housekeeper to be responsible for "accounting" (maintaining the system and entering data). But after using blockchain technology, the concept of this "central steward" disappears, and each of us can participate in accounting. So the question is, whose record will ultimately prevail? Of course, it is the person who completes the work well and quickly. A system that strictly adheres to fairness will select this person based on the algorithm, write the contents of his records into the ledger, and send the contents of the ledger during this period to everyone in the system. of others to make backups.

2. What is so powerful about blockchain technology?

Any new thing must have unique advantages if it wants to develop rapidly, and the same is true for blockchain technology. First of all, blockchain technology ensures the security of the system. In the absence of a central steward, everyone is a defender of the home, which means that destroying some nodes has no impact on the system at all. Second, the recording process cannot be cheated. Everyone in the blockchain system has the same ledger, and the entire process is open and transparent. The system will determine the final result based on the opinions of the majority. It is difficult for an individual to hack into so many computers at the same time, and it is meaningless to just modify one's own results. Who would do such a thankless task? Third, and most importantly, the blockchain completely abandons the existence of "credit intermediaries". Credit intermediaries are the platforms we must pass through when transferring money, such as traditional banks. Now any two strangers can directly complete mutual trust transfers, and the efficiency has been improved not only a little!

3. What is the use of blockchain technology?

As mentioned above, the main advantages of blockchain are that it does not require intermediary participation, the process is efficient and transparent, the cost is very low, and the data is highly secure. That is to say, any industry that has needs in these three aspects can use blockchain technology. Here are a few examples:

In the banking industry, the use of blockchain technology is equivalent to updating a digital, secure and tamper-proof General ledger books. In fact, Swiss bank UBS and Barclays Bank in the UK have already begun experiments, hoping to use it as a way to accelerate back-end system functions and clearing and settlement capabilities. Some institutions in the banking industry claim that blockchain may reduce middleman costs by 20 billion.

In terms of car rental, blockchain also has great potential. A future customer selects the car they want to lease, entering it into the blockchain's public ledger; then, sitting in the driver's seat, the customer signs the lease agreement and insurance policy, while the blockchain updates the information simultaneously. This is a foreseeable future for car sales and car registrations.

In terms of medical and health care, blockchain technology allows hospitals, patients and all parties in the medical benefit chain to share data in the blockchain network, and Don’t worry about data security and integrity. This means more accurate diagnosis, more effective treatment, and an improvement in the health system’s overall ability to deliver cost-effective care.

Blockchain is not cold-blooded. It has been implemented in applications that are closely related to our lives. For example, the application of Ant blockchain ranges from public welfare, to mutual insurance, to traceability of product authenticity, to traceability of rental housing.

In 2018, blockchain will "return to the world."

Blockchain, do you really understand it? Since it says three minutes, let’s give a simple answer.

1. What is blockchain;

2. What are the benefits of blockchain;

3. What are the uses of blockchain;

4. Blockchain technology and existing problems;

Let’s first look at the first question: What is blockchain

Let’s look at it literally. Blockchain is called Blockchain in English. This is a very good word. The English name is well chosen and the Chinese translation is also very beautiful.

1. What is a "block"?

You can think of it as a record, or anything, which forms such a record during the production stage. This thing can be any physical or virtual object in the Internet of Everything.

For example, if you generate a Bitcoin, which is a thing, it actually corresponds to a block. This block is a record of what it is.

When you produce a bottle of medicine in the future, a block is actually generated when this bottle of medicine is produced. When it leaves the factory, it needs to be recorded once, and this corresponds to it one-to-one.

This is the first dimension.

To make it easier to understand, for example, each of us is born with a unique identifier, which is our DNA. All species in the world have different DNA. Every individual's DNA is different.

Your parents can name you Zhang San, Li Si, Wang Wu. These names can be repeated, just like a bottle of medicine, whether it is aspirin or penicillin, these can also be repeated. famous. However, human DNA is different. Even if you have identical brothers and sisters, your DNA is different, so this is your unique identifier. And once your DNA is formed, it cannot be changed. This is a benefit of the blockchain.

2. What is "chain"? The chain is actually a process. You can think of it as a transaction process. After this bottle of medicine leaves the factory, it enters the warehouse from the workshop and passes through a certain door, and it will record the process.

Of course, this requires automatic computer recording, and the cost of human recording is too high. Then, packing is a process, and transportation to the cargo transfer station is another process. Then it is loaded into a car and transported to the wholesale station, which is the next process.

Every step of the process is recorded. It is a process to go from the wholesale station to the store, it is another process for the people in the store to receive this batch of medicines and put them on the shelves, and it is still a process for you to buy them. Finally, when the whole process is connected, you will have a way to track the entire process of this bottle of medicine and know its authenticity, because once this bottle of medicine is produced, it will be bound to the blockchain, as well as to people and people. The same is true for DNA binding, which cannot be changed, but it can be seen and detected.

The doctor can also determine whether this person is you by testing DNA. So in terms of nature, if we virtualize it, it is actually a smart contract. You have signed a sales relationship with one of your customers. Once this happens, it cannot be changed. Then everyone can only execute it. This execution process is the same as the tracking of drugs I just talked about.

Second question: What are the benefits of blockchain?

1. Mathematically speaking, it is very beautiful. It changes the past situation where you had to own something before you could know its properties to the situation where you don’t own it butYou can learn a lot about it by asking questions.

Mathematically speaking, this is a perfect asymmetric situation. You can tell whether it's true or false, but you can't change it.

2. Theoretically speaking, blockchain is very safe. For example, if you participate in the process of a bottle of medicine, others cannot see this information. That is to say When you buy this bottle of medicine, you can know where it comes from, but others cannot.

For the same reason, for example, if we sign a contract, others can verify the contract. If you go to a bank for a loan, he can ask you the amount.

However, he cannot obtain this contract, and he cannot steal this contract from your computer.

Blockchain also has some very interesting properties. For example, a block chain can be divided into two at will, or several can be combined into one, etc.

3. Blockchain is transparent, which means that everyone abides by this algorithm and there is no special agreement in private. So, if you believe in this algorithm, it means you believe in me and believe that I didn't do anything fishy. I will not secretly do anything in the contract to make you suffer losses.

This is a beautiful place theoretically and mathematically.

In the third block, let’s take a look at the uses of blockchain

1. Bitcoin is a cryptocurrency, and the Ethereum currency that everyone uses now is also a cryptocurrency. Of course, you can make another one based on it, either Zhang three coins or Li four coins. As for whether it can replace the currency of the future, this is doubtful.

2. Financing, we used to divide financing into three stages: the first stage is to get a loan from the bank. If you want to open a restaurant, you need to mortgage something. The second stage is that you issue some stocks and I sell 10% of the stocks, so that I can obtain part of the funds.

The third stage is actually crowdfunding. For example, if I want to write a book, it may cost 50,000 yuan for the publishing house to publish it. If any of you can give me 50 yuan at the beginning, I will use it in the future. Once the book is written, give everyone a copy. You will get the book, and of course I will publish it. But there is a problem. For example, I sell this book for 100 yuan and you get it for 50 yuan. What if my book sells very well, assuming I sell 100,000 copies, but you don’t seem to benefit from me? what to do?

Is there a fairer way to measure everyone's contribution? One way is to issue a cryptocurrency (ICO). When the business we do becomes bigger in the future, you can benefit from it.

3. Smart contract, for example, sign a contract. In the future, the smart contract can become like this. All the nodes in the middle are determined when the contract is signed, such as building or decorating a house for you. ,furnishAt which point your payment must be given to me. Once you have accepted it, no problem, the payment will be automatically given to me.

You can even sign with my supplier, which means that as soon as my money arrives in my account, I will give it to my supplier immediately. This will eliminate many triangular debt problems in the future, including the problem of arrears to migrant workers.

Blockchain can also be used for property registration, car registration, etc. Of course, another great use is gambling. In fact, gambling is the most willing to adopt new technologies because it is closely related to money.

After talking about the benefits of blockchain, let’s take a look at the technology and existing problems of blockchain.

Today’s blockchain is basically the second generation and the first generation. It is the Bitcoin generation. It has many problems. It is not a platform, but is actually a specific application.

The second generation is represented by Ethereum. It is a platform on which you can issue your own coins, and it removes the concept of mining machines, so its transaction costs will be much lower. . The reason why ICOs are everywhere today is because with Ethereum, you can issue coins. Unlike in the past with Bitcoin, you had to completely copy its formula and copy it again. Today you are on Ethereum. , it is easy to issue your own currency, just like you can easily make your App on the Android operating system today.

There are three problems with Bitcoin transactions

1. The transaction delay is very long. I asked people who specialize in Bitcoin transactions and the delivery time ranges from two hours to two hours. Days wait, so it is very inconvenient for you to use it to launder money. After the RMB is converted into US dollars, it may fall by 20% in two days, and you will lose 20% of your money.

2. It cannot be distributed. Like Bitcoin, the early people took away a lot of its shares, so how to distribute it in the future is also a problem. No one knows clearly, so it is difficult to use it as a currency. a currency. Because if it really becomes a currency that everyone uses, it will be equivalent to the first few people taking away a large part of the world's property.

3. Transaction costs are high. For example, a cup of coffee at Starbucks in the United States costs $2.50 on average. You usually pay money at the counter, and the transaction time is only one minute. If you want to use Bitcoin, you have to wait two hours before you can get your coffee, and the transaction costs are extremely high, the electricity bill alone is $20. In other words, if you pay $2.50 for coffee, the transaction cost of electricity is $20, so this is unrealistic.

Blockchain has high risks. This risk is not only a technical risk, but also a policy risk. In fact, this is also an opportunity. Whoever solves this problem will get the opportunity. Its transaction costs are also very high, so whoever can develop new underlying technologies and reduce this transaction cost will make a lot of profits in the future.

Some people say it is the next generation of the Internet.I don't agree with this, but it will definitely be a supplement to the Internet. Some people say whether it can subvert the central bank, but this is not certain, because there is no reason why the central bank or these big banks cannot do this themselves, so those who expect it to subvert the central bank may be too happy too early.

Perhaps in the end it was these large financial institutions in the past that used the blockchain to update themselves.

Talk in the vernacular and get useful information!

Literally, blockchain is blocks and chains, and some relationship between them. It is essentially a distributed accounting method and a network database system that cannot be tampered with.

The current development directions include digital currency, payment, smart contracts, defi finance, web3 and so on. It is still in the initial stage of development and is a back-end technology. Most projects are still speculating and financing.

Today’s Afghanistan may best prove the value of Bitcoin, and there is no problem with value storage

Blockchain is not just a technology, it is a way of trust transfer, value The way it is delivered may have huge potential in the future.

Keywords: block, chain, database, ledger, Afghanistan, currency speculation, value, technology, market

First, what is a blockchain? Blocks and chains are an accounting method and a form of network data storage.

Literally speaking, blockchain refers to blocks and chains. This block actually records the transaction records of the entire network, or the execution result data of smart contracts, etc.

Every once in a while, the entire network will produce a block. This block records all transfer data, and the blocks need to be connected by some kind of "chain".

This chain is an encryption algorithm. Some information of the previous block is used to calculate and obtain certain information of the next block. They are linked together. The latter block can trace back to the previous block and needs to be modified. The next block must modify the previous block, all the way to the first block. Regarding the details of these issues, I have written many articles before. If you are interested, you can go back and take a look.

Blockchain is actually an accounting method, or a database storage method. Please pay attention to what I say below. The whole process is the operating mechanism of blockchain.

Each node in the entire network has the same status and runs the same program. This program is used to collect, encapsulate and package all transaction record data records that occurred in the entire network within a period of time. Then broadcast it to the entire network

Let’s take Bitcoin as an example. Once this packaging and encapsulation is completed, you can obtain the right to produce the block. A certain amount of Bitcoin can be issued every time a block is produced. Since the nodes in the entire network run the same program, there is no center to control everyone. Therefore, the currency issued is irrevocable and cannot be changed.

How to decide whoDo you have the right to make money? This requires the use of the so-called consensus mechanism, which is to establish a rule and use who produces the block as the benchmark to solve the problem of network consistency. The mainstream consensus mechanisms include POW mechanism and POS mechanism. Proof of work and proof of stake. Proof of work, who does more work, and proof of equity, who stakes more assets

Pow means that everyone calculates a difficult mathematical problem together, whoever calculates it Whoever comes out has the right to produce the block. Pos means that everyone takes out their family assets as mortgage, and whoever mortgages more. It is possible to be selected as a block producing node.

The essence of this approach is that you have to pay a certain price and receive a certificate of investment, which essentially builds a kind of trust.

When all these tasks are completed, a block can be produced, and the block will be connected to the previous block one by one. This is the entire block sequence. Note that the entire blockchain world will produce many blocks, connected to one chain after another, but everyone will only recognize the longest chain, and short chains will be discarded.

To put it simply, each network node uses a program to package transactions within a period of time, and then connects the transaction blocks one after another and saves them in each node, but an encryption algorithm will be used in the process. Ensure that node information is not leaked, ensure that user information is encrypted, and ensure that the information in the block is not cracked or tampered with

Second, the block The current development of the chain, various projects and significance, at this stage are more about currency speculation, and there is no problem with value storage.

Blockchain has been developing for twelve or three years since the Bitcoin white paper in 2008. It has also experienced various evolutions and developments.

For example, now it has gone from being able to issue currency in a distributed way to now having huge functional expansion. The landmark event is the birth of the Ethereum smart contract.

I have explained many times that a smart contract is an automated contract signed by two or three parties. It will be automatically executed as long as the conditions are met. It is essentially a program with infinite possibilities and the judge in the blockchain world. Various functions can be input into the program, and the program exists. Blockchain has become rich and colorful.

Current blockchain applications mainly include the following aspects: smart contracts, payments, cross-chain assets, oracles, defi, web3 storage, etc. I will briefly mention two. Let’s take an example and talk about its commercial application.

For example, defi applications are quite popular on Ethereum now. Defi is decentralized finance. Abbreviation for decentralized finance.

What does it probably mean? It is to move all financial-related businesses in real life, such as mortgages, insurances, and loans, onto the blockchain.

This field is very popular now, and the reason is simple. It is very suitable for blockchain. As I said, a smart contract on the blockchain is a contract. If the contract conditions are met, execution can be automatically triggered.

In the past, it might have been very troublesome for you to go to the bank to apply for a loan. You had to sign various signatures and verify them, and the bank might not be open on weekends and nights

But with blockchain The network operates 24 hours a day. If you want to run various assets on it and do various mortgage transactions, you only need to click and there is a software terminal.

Of course, the real assets will be frozen in the process and mapped to virtual assets. After the transaction is completed, they will be exchanged for real assets. Cross-chain technology and oracle technology may also be used in this process, which I have written in detail in other articles.

It roughly means cutting off banks through decentralization, and direct point-to-point transactions. The security of transactions is guaranteed by blockchain technology, code and cryptography.

There is also the current web3 storage class. For example, the leading project fil. His vision is to take out all the scattered hard drives. Break all the data and information that need to be stored on the network into small pieces

and then distribute them to the entire network. When we want to use network data in the future, we no longer need large network database or server. In this way, Internet giants cannot charge high service fees. There is no way to maintain a monopoly.

If you want to obtain stored information, just take a taxi online like dd. You pay for a taxi, so that information on the Internet can flow freely. Costs will drop significantly.

Of course, these visions are grand and huge, and the current blockchain development is still in its early stages. There are still some technical difficulties to be overcome and some underlying systems to be established, but there is no problem in this direction.

The original digital asset projects like Bitcoin have now been proven to be very safe. Just like this situation in Afghanistan, the first thing that comes to my mind is Bitcoin. He is the first violent and unplunderable asset.

Your house may be occupied and blown up, and your gold may be robbed. And if you have Bitcoin, it's much easier. He can't snatch this thing away, because the mnemonic phrase and private key are in your mind, and he doesn't even know whether you have this thing in your mind. If you want to pass it on to your child, just ask him to memorize the key and mnemonic phrase.

It is precisely because we are now in a stage of financing and bubbles that all the news you see on the Internet is still speculation.

Also, this thing is a back-end technology. For example, Guangdong Province already has blockchain invoices. For example, there are already some blockchain apps for judicial certification, but for the front-end For you, you can't feel it. There is an extra string on the invoiceHash encoding, can you tell what the difference is?

This is why when it comes to blockchain now, everyone is speculating on coins, but in fact it has certain applications and future technical logic.

Third, it is essentially a mechanism of trust, a method of value transmission, and an exploration of social governance methods.

What is the essential value of blockchain? The most important thing is that it is a way of credit transfer. Because there is enough credit, real-life assets and property values ​​can be spread on the Internet in the form of information codes.

Mainly in these aspects.

First, before Bitcoin, people did not know how to protect a piece of information, because information on the Internet can actually be copied. Bitcoin solves the problem of uniqueness of information assets. With scarcity, there is value in transactions and storage.

The second is decentralization and disintermediation. We used to do everything. All require some kind of intermediary. For example, when you borrow money, a bank acts as an intermediary, and when you buy a house, various institutions and real estate agencies act as intermediaries.

You cannot buy or sell directly. Because you don't have enough credit. We usually come to find a third party, but the third party is usually made up of people and may also do evil.

For example, the master who could whip five lightning whips a while ago. If he calls you all kinds of names at the beginning, you may be frightened. You won't know he is a liar until he is punched and lying straight there. This is human credit, which is unreliable

Blockchain ensures credit through code, cryptography, and consensus mechanisms. We no longer need a powerful third party. Note that this third party will often become a monopoly boss.

The third is to reduce the cost of coordination, communication and entry barriers.

If we want to become richer, we need to trade in the market. And transactions require coordination and division of labor. Essentially, the companies and organizations we work for are intermediaries.

You have to integrate your resources through this kind of intermediary, transform your labor force, your brain power, and your ingenuity into final products and sell them on the market.

The smart contract technology of blockchain technology can break up these contracts in a decentralized manner. People in the market can combine freely to establish a new type of organization that is completely transparent and cannot tamper with the rules, which is a blockchain autonomous organization. The future of this kind of organization may be more promising than that of ordinary joint-stock companies.

You can join or quit an organization at will, and the trust between you and others has been resolved. You can cooperate with others and sign smart contracts to complete joint collaboration and complete a certain product. We no longer have to worry about some big capitalist taking advantage of everyone and getting the bulk of the profits.

So BitcoinBlockchain is essentially a large social experiment, through consensus mechanism, decentralized decision-making, and distributed signing of smart contracts. Gradually and completely change the original appearance of our society. Restore the original ideal of market economy, peer-to-peer, direct transactions between people.

To summarize. Blockchain is a block of information connected together through an encryption algorithm. It is essentially an accounting method and a network data structure

Through decentralization, you can do finance, storage, and decentralize many things, but now it is still very In the initial stage, most projects are still in the stage of speculation, financing and concept development.

The value storage capability of the blockchain has been proven to be problem-free, very safe, and cannot be plundered by violence.

The essence of blockchain solves the problem of credit intermediary, and at the same time can reduce the cost for people to work together, lower the threshold for enterprise entry, improve social efficiency, make social transactions larger, and allow We are richer.

I recommend the book linked below, it is easy to understand. Like You Pump tells the history of the birth of blockchain, the underlying technical logic of blockchain, and some mainstream projects. Learn some knowledge about blockchain, feel more at ease, and no longer worry about whether it is a scam.

『Lu』 What kind of blockchain projects can you make money by investing in?

Third, you must have investment protection mechanism.

The investment protection mechanism is easy to understand but difficult to implement. Investment protection mechanisms include: legal protection mechanisms and return protection mechanisms.

The legal protection mechanism of course refers to legal compliance, which is best reflected in the form of a contract agreement. This approach cuts off the escape route and allows some people with ulterior motives to escape. There is no opportunity for people to take advantage of.

The guarantee of returns is direct cash dividends. This is also an extremely important point in investment standards. Users must be given cash dividends, and sharing shares with coins is fake. It is not as practical as getting cash in your hands. Most people are small and medium-sized investors and do not have that much money to lose, unlike large investors who can forget about losses. If small and medium-sized investors lose money in their investment, it will be fatal, and the family may even have no way of living from now on. Therefore, distributing cash may seem demanding, but it is actually a kind of protection for investors. If you want to live a few more days, you have to ask for this.

Some dividend disks split the disk and give you some coins. Is it useful for you to hold it? If it can't be sold at all, then it's still equal to zero. It's different if you give cash. If you give cash, you can use it immediately after you get it. It's hard currency.

At the same time, the cash distribution can also show the determination of the project party and whether it is really doing something. One investment corresponds to one dividend. If it is not a project that is really doing something, can the cash be used to distribute it? Just kill it! So, split the cashThis approach is also an investment standard for many current projects.

Blockchain is the future trend, we all know it. Blockchain projects are also very promising, we also know this. However, as to what the blockchain project is like and how to do it, whether it is depositing coins to earn interest or wallet mining... we don’t have to spend time to understand and figure it out. There are some things that we may never understand in our lifetime. Then just choose based on these criteria. If all three conditions are met at the same time, you can invest and there is a high probability that your investment will double. If the three conditions are not met at the same time, then you can wait to protect your rights.

The industries created by blockchain will benefit. Due to the high degree of integration, blockchain technology can not only benefit the financial field. Enterprises can provide technical support or meet scenario needs. They can also use their own characteristics such as high-end equipment to have a catalytic effect on some manufacturing enterprises after the integration of manufacturing industries.

WithAs blockchain technology gradually matures, the six major areas supported by the Science and Technology Innovation Board will adopt more and more technologies. A research report released by Lianxun Securities shows that with the help of policy dividends and industrial capital, the application of blockchain technology is expected to be rapidly developed in the future. development, and gradually radiate to other industries and scenario applications starting from the financial industry.
