❶ The future prospects of blockchain e-commerce

This development model has great 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.

❷ Blockchain Medical Big Data Project Business Plan

Recently, according to people familiar with the matter, Son Zhengyi invested in the blockchain animation project Myou, which was founded in Singapore. A non-profit organization that creates a new form of collaborative creation ecological network for the global animation field based on blockchain technology. Let animation creators around the world connect quickly and effectively to form a new production and creation method.

As we all know, Masayoshi Son is very strict about the screening of projects. He has always only invested in projects that can implement blockchain technology. In the field of investment, he focuses more on supporting game-type projects. He believes that this field has great application scenarios. Relatively extensive.

He said that there are two main reasons for investing in Myou this time: on the one hand, the market in the animation industry is huge and there are business opportunities; on the other hand, due to the strength of the Myou project team, it is completely possible Realize the implementation of blockchain technology in the animation industry.

Optimistic about the animation industry, a 100-billion-dollar market to be tapped

According to a recent report released by the investment bank Digi-Capital: the market size of the animation industry is growing at an annual rate of 50% Increasingly, global animation software and hardware revenue will exceed 200 billion US dollars in 2019 and will exceed 250 billion yuan in 2020.

However, in a market worth hundreds of billions of dollars, there are fewer and fewer classic animation IPs. In the current centralized animation industry, profits are almost monopolized by giants, and animation is highly homogenized. Due to lack of funding, the living space for outstanding artists and teams is very limited, and good animation IP ideas are often stillborn. As the industry gradually reaches a stalemate, the quality of animation will decline inevitably.

Now, Myou is aiming at the huge development potential of the animation industry, investing a lot of manpower and material resources, adhering to the concept of a highly liberalized animation ecological environment, and is committed to creating a decentralized animation ecology and promoting the animation industry. path of healthy development.

What potential does Myou have to attract Masayoshi Son?

There is no doubt that the centralized traditional animation industry is in urgent need of change. Myou’s founding team strives to create a competitive industry from all dimensions. The project strives for excellence in terms of technology and team. In order to better develop the market in the future, we strive to reach cooperation with Japanese institutions such as SoftBank, Sony, and Shueisha.

Technical advantages. The ecosystem Myou wants to create is fair and transparent for creators, businesses and consumers.Ecological platform, unlike other platforms, Myou provides a groundbreaking incentive and multi-level recommendation system, allowing users to earn income in animation and social activities, as well as earn rebates from other users' payments. Through Myou developers will reduce their marketing expenses and gain additional revenue from other anime on the platform. In the process of users and developers contributing to the platform, the platform will reward them in the form of reward tokens.

Myou’s core logic and animation operation logic are implemented based on smart contracts, and key data such as all animation digital assets, core operations in the animation process and random number generation results are recorded on the chain, and all actions are public transparent.

Myou mainly uses the main chain and multiple side chains to achieve ecological layout. Considering the high-intensity interaction and high real-time requirements of animation scenes, the Myou protocol adopts a higher-throughput PoWPoS consensus main chain and cooperates with multiple animation/functional side chains with their own consensus mechanisms to achieve both security and efficiency. Among them, the main chain adopts a hybrid consensus mechanism of PoW (ProofofWork) and PoS (ProofofStake).

Financial advantage. In addition to Masayoshi Son's investment this time, the Myou project has already attracted the attention of venture capital, and has reached cooperation agreements with Japan's SoftBank, BA Capital, Coin Capital, FUNK Capital, Genesis Capital, Wanlian Capital and other institutions. In the future, with the support of capital, projects will be accelerated.

In addition, Sony, Shueisha and other companies have also reached strategic cooperation with Myou. With the efforts of many parties, more brand customers are encouraged to put animation IP copyrights on the chain, which will help Myou quickly enter the animation market.

Team advantage. Myou's CEO Reza Far won the TOP10 Canadian Young Entrepreneur Award in 1998, 1999, and 2001. He holds important positions in many groups in the Middle East, covering industries such as real estate, information technology, logistics, and crude oil.

CTO IvanKoma once worked at Microsoft Research as a senior software engineer and has unique insights into blockchain technology.

CFO Manuel Giner is an MBA from New York University, an EMBA from the University of London, a double bachelor's degree in finance and accounting from the University of Barcelona, ​​and a CFA holder. He has worked in well-known investment banks such as Goldman Sachs, Citigroup, and Blackstone, and has more than ten years of experience in traditional industries and sectors. Working experience in chain industry investment analysis.

At the same time, the rich background of the consulting team is worthy of everyone’s attention. Heyuan Lingxu created the BGM of Hunan TV’s “Where Are We Going, Dad” and the theme song of Tencent’s “Honor of Kings”. Haruka Nagumo, chairman of the International Color Association and professor at the Line Design Institute of Communication University of China, author of "Hunter Hunter" and final candidate for the Tezuka Award, Yuki Maeda, has directed Ritz-Carlton Royal Hotel and St. Regis Hotel Etiquette expert Junko Kato.

"Those who wait and see will be eliminated"

p>

The architecture of the underlying technology of blockchain can solve the essential problem of centralization in today’s business districts. The concept of blockchain will become the basis of trust and credit mechanism in the future business field. Hubers has long realized that blockchain is a disruptive technology, and he believes that those who wait and see will be eliminated.

Myou is just one of the projects he has invested in the blockchain field. In the future investment layout, he will rely on the financial and resource advantages of NutsCapital Fund to continue to delve deeply into the blockchain field and explore more potential projects. potential projects.

NutsCapital has currently established branches and professional teams in China, the United States, Singapore, Japan, South Korea and other countries to achieve a global blockchain ecological layout.

❸ The future development prospects of blockchain

1. Blockchain has become the forefront of global technological development and opened up a new track for international competition. Blockchain will become a new key infrastructure to further accelerate the development of the digital economy, lead a new round of global technological change and industrial change, and become the "source" of technological innovation and model innovation. The world's major developed countries will further pay attention to blockchain technology, intensively introduce relevant policy plans, increase industrial support and guidance, and enhance the competitiveness of their country's blockchain technology and industry.
2. The digital currency bubble gradually cools down. With the spread and popularization of the concept of blockchain technology, more and more people will realize that Bitcoin is not the same as blockchain, and various air coins will be gradually eliminated. Blockchain technology innovation will return to a more rational track. Technical features such as decentralization, multi-party collaboration, and anti-calculation tampering will be highly valued by relevant industries. Some industries with strong innovation capabilities will continue to emerge with blockchain applications that have been transformed based on industry characteristics.

❹ What is the development trend of blockchain, and what is the development trend of blockchain technology?

The development trends of blockchain are:
01. The long-term direction of the blockchain industry Well, the core value is generally recognized;
02. Technology development is more pragmatic, with engineering and ecological construction becoming the focus;
03. Blockchain and privacy computing develop collaboratively;
04. Blockchain Chain interconnection has become the focus, and the future of value interconnection is promising;
05. The call for blockchain infrastructure is gradually rising, and the construction model still needs to be explored in depth;
06. Blockchain cannot conquer the world, and needs to cooperate with many Technology cooperation completes digital transformation;
07. The application of certificate storage takes the lead, gradually moving towards multi-party collaboration and value transfer;
08. The importance of the blockchain alliance business model is further highlighted;
09. Government Support will still be an important driving force for industrial development in the future;
10. As the scale of blockchain practitioners increases, the relative shortage of talents will continue to exist.

(4) Extended reading for future business of blockchain:
Blockchain is a chain composed of blocks one after another. Each block stores a certain amount of informationInformation, they are connected into a chain according to the time sequence of their respective generation. This chain is saved in all servers. As long as one server in the entire system can work, the entire blockchain is safe. These servers are called nodes in the blockchain system, and they provide storage space and computing power support for the entire blockchain system. If you want to modify the information in the blockchain, you must obtain the consent of more than half of the nodes and modify the information in all nodes. These nodes are usually in the hands of different subjects, so it is extremely difficult to tamper with the information in the blockchain. thing. Compared with traditional networks, blockchain has two core characteristics: first, data is difficult to tamper with, and second, it is decentralized. Based on these two characteristics, the information recorded in the blockchain is more authentic and reliable, and can help solve the problem of people's mutual distrust.
Blockchain is still mainly used for certificate storage. For example, the application of blockchain in supply chain finance, product traceability, trade finance and other fields has achieved certain results, but its application model is still based on documents, contracts, The main thing is the deposit certificate of the bill. As the industry application of blockchain continues to deepen, in order to further promote the role of blockchain in promoting the development of the real economy, in the future, we will focus on the development of multi-party collaboration and value transfer applications.
Blockchain is not just a technology, but also a concept and a cooperation model. Blockchain will connect upstream and downstream parties in the industry, and it is necessary to rely on the common interests of the alliance to bring together all participants. At present, there are two main organizational models of blockchain alliances, namely, core organization leadership and participating organizations co-governance. Both blockchain alliance business models also have their own pros and cons. For the long-term and stable development of the alliance, how to build and which kind to build The model also requires continued in-depth exploration by the industry.

❺ What is the future prospect of the blockchain industry?

Main companies in the industry: Tianzhou Culture (300148), Meiya Pico (000607), Hua Media Holdings (300188), Digital Video (300079), Jinyun Laser (300220), Nantian Information (000948), Borui Communication (600880), Annie Shares (002235)

The core data of this article: Global blockchain market size, global area Regional distribution of blockchain investment and financing events

The scale of the global blockchain industry is growing rapidly, and application scenarios continue to expand

According to IDC data, in 2020, the scale of the global blockchain market will be stable growth, reaching $4.31 billion. Affected by the new round of regulatory policies on the blockchain industry in European and American countries, the growth rate of the global blockchain market has declined compared with 2019, reaching 53.97%, and is expected to reach US$14.533 billion in 2023.

Equity investment events account for nearly 93%

In 2021, a total of 1,786 investments and financings occurred in the global blockchain. Among them, there were 1,659 equity investments, accounting for nearly 93% of the total investment and financing. In addition, there were a total of 64 mergers and acquisitions, 13 listings and 50 token financings.

Equity investments in the Americas, Europe and AsiaMost active

Judging from the regional distribution of the number of equity investment events, the Americas have the largest number of blockchain equity investments, with a total of 542 transactions occurring in 2021, accounting for 33%. Followed by Asia and Europe, accounting for 18% and 15% respectively, there is not much difference. Overall, the number of equity investments in the three continents of the United States, Europe and Asia accounts for more than 65% of the global blockchain investment and financing.

From the perspective of amount distribution, the amount of blockchain equity investment in the Americas in 2021 reached 128.975 billion yuan, accounting for more than 50%, reaching 56%. In terms of equity investment amount, Europe overtook Asia, accounting for 24% of the investment amount, which was double that of Asia (12%).

The United States "far surpasses Tongji"

At the national level, the United States ranks first with 484 equity investments and a total investment amount of 116.773 billion yuan. Far exceeding the second-place China with 97 investments and investment amount of 11.285 billion yuan, Singapore and the UK ranked third and fourth with 91 investments and 88 investments respectively. In addition, the number of equity investments in other countries is less than 50.

The above data refers to the "China Blockchain Industry Market Foresight and Investment Strategic Planning Analysis Report" by the Qianzhan Industry Research Institute.

❻ The future development prospects of blockchain will profoundly affect three aspects

It is still unknown how much technological impact blockchain will bring to the human world, but industry, academia and research generally believe that at present We have only seen the tip of the iceberg of blockchain’s potential value! Blockchain technology will not only change technology and reshape industries, but will also shake the existing order, traditional rules and value systems of human society. As blockchain technology gradually matures, it is foreseeable that blockchain will show the following development trends.

Zero-knowledge proof

Blockchain is very transparent in nature. Any node running in the blockchain network can view and download all data stored in the ledger. Blockchain combines zero-knowledge proof technology to allow users and businesses to use private data to execute smart contracts without revealing specific data content.

Artificial Intelligence

Blockchain can serve as the foundation for decentralized markets and a coordination platform for various artificial intelligence components, including data, algorithms, and computing power. This could lead to new levels of innovation and use of artificial intelligence. Blockchain will also make such decisions more transparent, explainable and trustworthy. Since all data on the blockchain is public, artificial intelligence will become the basis for providing anti-counterfeiting and privacy protection.

Internet of Things

Blockchain can add a layer of accountability and security to IoT data, becoming the future driver of IoT efficiency, scalability and standardization By. For example, in healthcare, blockchain-enabled IoT devices will allow patients to control access to the data collected by these devices. This technology will make devices more resistant to cyberattacks andProvide detailed records of when data was accessed by another party. In supply chains, blockchain-based systems, powered by smart contracts, can automate payments based on specific conditions measured by IoT sensors.

The arrival of the blockchain era has revealed the future development trends of various industries, and the increasingly mature technology of blockchain has gradually entered a period of expansion. I believe that in the near future, it will definitely produce greater economic benefits for society.

❼ What is the most important change in the blockchain business model?

Blockchain-based intellectual property protection It is possible to establish truly unique intellectual property rights in the blockchain. The first is authentication and the second is protection. Some media groups want to ensure the authenticity of data based on blockchain and real accounting in the future.
2.
If a platform like this is established for micro-knowledge content, micro-notarization, micro-publishing, and public innovation, a large number of Weibo and WeChat, including what I said today, will be original. , will be registered on the blockchain at a very low cost. After registering, you can micro-publish. It will be profitable in the future. Even if everyone uses it, I'll get a penny. That's a lot of profit. How big is the market? This is definitely not about using traditional publishing houses to take away their publishing market of more than 1 billion pounds. That's worth tens of billions of dollars.
3.
Wearable instruments and blockchain medical records At present, due to the lack of smooth communication of information, there is a great conflict between doctors and patients. Originally, everyone’s medical records

❽ How to introduce 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, Ant Financial An engineer 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 suddenly received 381 A letter of love.

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.Some others 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 earlier, 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, andImprove the health system's overall ability to provide 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.process, and then load it into a trolley and transport it to the wholesale station. This 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 tested.

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 from the past that you had to own something before you could know its properties to that you don’t own it, but you can ask questions Learned many details about it.

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. 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 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,To get a loan from a 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. , your payment must be given to me at any stage of the decoration. If you accept 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 save 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 have 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. Unable to be distributed, like Bitcoin, those early people took away a lot of its shares, so how to distribute it in the future is also a problem, and everyone has not made it clear, so it is difficult to use it as 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 be the best proof of 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 process 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 certain information of the next block. They are interlocking. The latter block can trace back the previous block. To modify the next block, just You have to 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 who has the right to make a block? 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 only recognizes 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 hacked 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. In the middleIt has undergone 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 relatively grand and huge. The current development of blockchain is still limited.It's very early days. 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 of hash codes on the invoice, can you tell the difference?

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 brainpower, 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 the Bitcoin blockchain is essentially a big social experiment, through the consensus mechanism, the decentralized decision-making method, and the 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.
