Ⅰ Several of my friends are playing with blockchain, is it reliable?

Blockchain is also a relatively new thing, and there are many people They all pay special attention to blockchain. Blockchain can be loved by many people, and it can also receive investment from many people. Many people particularly want to invest in blockchain, and they also hope to make themselves better by investing in blockchain. Get more bang for your buck.

There are many people who want to invest in the blockchain, but they may not necessarily understand the blockchain, and they do not know how to operate the blockchain. If everyone around them invests in the blockchain, they themselves If you invest, you may suffer relatively large losses. Some people may have this question: Several of my friends are playing with blockchain, is it reliable? In fact, I think blockchain is not necessarily reliable. There are three main reasons why I say this:

First, blockchain is easily affected by the market.

The reason why I think blockchain is not necessarily reliable is because I think blockchain is easily affected by the market. When the market fluctuates greatly, the value of blockchain may increase. decline, and it may not be able to recover as soon as possible. If some people invest because of the value of the blockchain, they may suffer relatively large losses, and they may lose all their money.

The above is my opinion.

II Does blockchain have any practical application value?

The current application value can be divided into: 1. Financial stored value: The characteristics of Bitcoin’s limited total amount and easy circulation make it It has become a good means of storing value and is also known as "liquid gold". Especially in some war-torn and turbulent areas, the rapid depreciation of the local legal currency caused local people to buy Bitcoin frantically. For example, during the 2017 coup in Zimbabwe, the country's currency price was once twice the global market price. In addition, whenever South Korea's northern neighbor launches missiles, it will trigger Koreans to buy coins frantically and drive up the price of coins; Payment: Currently, not many support the use of cryptocurrency for payment, but Japan is at the forefront of other countries. Many merchants and supermarkets in Japan have already supported Bitcoin payments, and some institutions in the United States and Europe have also begun to accept Bitcoin payments. 2. Credit information recording and notarization One of the core features of blockchain technology is that information cannot be tampered with after being recorded. This feature still has great application space in the fields of credit and justice. To give a simple example, food safety issues are largely caused by the opacity of information in the production, processing, transportation, and sales of food. If blockchain technology is used to record the specific information of each link, it can be ensured that every item Food information in every link is traceable, searchable and unchangeable, which will greatly alleviate food safety issues. Of course, the above example also involves other mature technical capabilities, such as the need for automated collection of information, which is the so-called Internet of Things. In addition, blockchain technology has begun to be introduced in terms of contract fairness, real estate information recording, and even the EU's information registration of Middle Eastern refugees. 3. Smart contracts are talking aboutBefore smart contracts, let’s first introduce the currently more mainstream Ethereum platform. It provides a basic development platform for blockchain, so that blockchain application developers do not need to develop from the bottom, and only need to apply it on Ethereum. Just develop. It can be compared to the Android platform. With Android, application developers only need to develop applications based on Android, and the cost is reduced a lot. On top of Ethereum, developers can implement smart contract programs. The so-called smart contract means that after the system determines that a condition is reached, it automatically triggers the corresponding follow-up reaction. Take aviation delay compensation as an example. Last time my flight was delayed, I applied for delay compensation from the credit card company. The whole procedure was very troublesome. If smart contract technology is used, the system can read that the flight has been delayed and can automatically credit it to my account. By depositing compensation, the efficiency of the entire process is greatly improved, and there is almost no operating cost for me and the credit card customer service staff. 4. Reduce settlement costs. Take Ripple as an example. Ripple is an open payment network. Through this payment network, you can transfer any currency, including US dollars, euros, RMB, Japanese yen or Bitcoin. It is simple, easy and fast, and the transaction is confirmed in a few days. It is completed within seconds, the transaction fee is almost zero, and there are no so-called inter-bank, long-distance and cross-border payment fees. Just entering 2018, Ripple also skyrocketed because it was introduced into the settlement system by banks in Japan and South Korea and began testing. Its total market value surpassed Ethereum and was second only to the oldest Bitcoin.

Ⅲ Does blockchain have development prospects in the future?

A series of large companies such as Tencent and Alibaba are all trying to share and seize the blockchain cake. Do you think it has development prospects? Of course there is! Below are the top ten predictions of the China Academy of Information and Communications Technology on the global blockchain. I hope it will be helpful to you! !

< /p>

From the current market media information, we can see that blockchain information has occupied the major media landscape. It is not an exaggeration to say that it is in the center of the storm. The appropriate metaphor is that it is in the center of the storm.

Why does the blockchain become so popular all of a sudden? Let’s talk about the currency circle. For example, a mainstream currency actually appeared a few years ago, but because the individual value direction is not recognized by people, it is not It is worth entering the public eye. After several years of skyrocketing, it seems that some potential human nature has suddenly been activated. It is similar to buying a house. Everyone cannot understand it. It is tempting, explodes, and then activates greedy human nature. Then the information exploded all at once. Seeking knowledge is what everyone wants to know about how coins are produced and how coins are created. So this is how the term blockchain was discovered.

Back to the topic, there is a difference between the currency circle and the blockchain. The currency is just an extension of the blockchain, and the blockchain is the underlying development structure of the currency. Blockchain uses code architecture to build a data distribution architecture similar to a spider web. The information in each link is a storage node, which is different from the previous centralized information storage centers. If you want to modify one of the links, other storage information nodes do not allow it, and you cannot modify the underlying information. This kind of storage center Optimized information distribution is theoretically safer and has better information flow. Just like a house, the framework determines the layout of the house and the comfort of lighting. The principle of building the code architecture is also critical. The specific architecture of the blockchain There is currently not much reference information to what extent the utilization value can be achieved, but large companies have begun to make plans. Judging from the current popularity of the currency circle, the financial attribute field of blockchain is more attractive than other fields. .

The development prospects of the future blockchain are certain. If you want to understand the prospects of the blockchain field, you still need to have a deeper understanding of what the big guys in the current blockchain field are doing. For example, a certain investment giant What are V people doing using blockchain? The direction they are taking has set the benchmark for the development of this field to a certain extent.

I still advise that there are risks in certain coins, so do it and cherish it.

The prospects are great

Blockchain is known as the next generation of disruptive core technology, and some scholars believe it will redefine the world. Our government also supports blockchain technology. All its codes are transparent and each personal information is stored on a separate chain. Compared with the current leakage of personal information, the emergence of blockchain will effectively solve this problem. Question, secondly, there are many other applications of blockchain, private messages that need to be understood!

The current public misunderstanding about blockchain is mainly due to the state’s jurisdiction over digital currencies. The emergence of digital currencies has greatly threatened legal tender. The state has no control over this uncontrollable currency. Supported! However, if digital currency can be effectively popularized in the future, this decentralized currency will be even better than legal currency in terms of security and cost.

Based on the above personal opinions, if you are interested in blockchain and digital currency, please feel free to discuss in private!

Judging from the current situation, it is relatively simple for major Internet companies to test blockchain application functions and is still in its infancy. The real potential application space of blockchain (finance, government affairs, medical care, etc.) is still huge, and it will take time to slowly explore it. In the short term, it does not yet have the conditions for large-scale implementation. However, recently, major Internet companies have frequently deployed blockchain technology, which has played a positive role in cultivating and promoting blockchain in my country's market. Especially in the A-share market, it has attracted strong attention from investors. China Merchants Securities believes that through the conduct of major Internet companies, the audience of blockchain will gradually expand from niche players to the general public.

The current trend is good.

1. Distributed ledgers improve social efficiency.

2. Certain industries can reduce the need for intermediaries.

3. The development of storage and computing performance may bring more industry opportunities.

Bitcoin can solve these problems, and Bitcoin is BSV.

To be honest, the prospects are very good! If you want to talk about digital currencies like Bitcoin, I think the prospects are not great now. Firstly, because mining is now very difficult and it is basically difficult for individual users to mine it, but because the volatility is too high and the water level is too high. Deep down, investment is basically about losing more and making less. The money that can be made is miners and exchanges.

But blockchain is different. Blockchain is a technical and knowledge-based thing. It can be used in many aspects, such as shopping transactions, transportation and logistics, finance, insurance and many other aspects. It can be applied. Not many banks are now cooperating with Internet companies to develop blockchain.

Therefore, blockchain should have good application prospects in the future, mainly because the technology itself has many advantages and has a wide range of applications.

Blockchain definitely has development scenarios! Blockchain technology can be applied in many fields, including finance, insurance, and shopping transactions. And due to the advantages of the blockchain itself, decentralization, asymmetric encryption, etc. are a good way to solve the current trust problems in people's production and life. The future prospects of digital currency may not be great, but I think blockchain has huge room for development.

Qianzhan believes that China’s blockchain market will maintain rapid growth, with a compound annual growth rate of 73% in market size from 2021 to 2026. The market size in 2026 will reach US$16.368 billion, and in the next 20 years , China’s blockchain industry market size is expected to reach the trillion level.

China’s blockchain industry market is developing rapidly

From 2017 to 2020, large IT Internet companies have deployed blockchain, start-ups have entered a blowout mode, and the industry scale has continued to expand. According to IDC According to the data, China's blockchain industry has experienced changes from a market size of US$85 million in 2017 to an industry scale of US$561 million in 2020.

In terms of the number of enterprises, in 2020H1, my country provided blockchain professional technical support, products, solutions and other services, and the number of new blockchain enterprises with input or output reached 303, a year-on-year increase of 274.07 %.

China’s blockchain patents account for a large proportion of the world, and the industrial aggregation effect is beginning to show.

From the perspective of the global competition landscape, my country’s competitive advantages in the blockchain industry are relatively obvious. Judging from the number of patents, according to the global authoritative third-party intellectual property agency IPRdaily and incoPat Innovation Index Research Center released data from the "Global Enterprise Blockchain Invention Patent Ranking in the First Half of 2020". The TOP 100 companies mainly come from 14 countries and regions, with China accounting for 46%, followed by the United States accounting for 25%.

As an important carrier for the development of blockchain industrial clusters, local governments are accelerating the construction of blockchain industrial parks. Judging from the location distribution of industrial parks, there are a large number of blockchain industrial parks in cities such as Beijing, Shanghai, Hangzhou, Guangzhou, Chongqing, Qingdao, and Changsha, forming a Bohai Rim agglomeration effect dominated by Beijing and Shandong, with Zhejiang and Shanghai , the agglomeration effect of the Yangtze River Delta dominated by Jiangsu, the agglomeration effect of the Pearl River Delta dominated by Guangdong, and the agglomeration effect of Hunan, Guizhou, and Chongqing dominated by Chongqing and Hunan. In the future, China's blockchain industry is expected to accelerate development relying on the aggregation effect.

The blockchain financial field is the most widely used

my country's blockchain industry applications are mainly distributed in finance, supply chain, traceability and hardware, accounting for nearly 65%. According to the "Blockchain Blue Book: China Blockchain Development Report (2019)", there are nearly 28,000 blockchain companies in the country. Among them, about 1,000 blockchain companies have been put into production, accounting for only 3.6%. They are mainly concentrated in developed eastern regions such as Beijing, Shanghai, Guangdong, and Zhejiang.

The market capacity of the blockchain industry is expected to reach trillions in the future

Blockchain technology is a key direction for China’s new generation of independent innovation breakthroughs in information technology, and contains huge space for innovation. In the fields of chips, big data, cloud computing and other fields, innovation activities are becoming increasingly active, and innovation elements are constantly accumulating. The application of blockchain technology in various industries continues to deepen, which will give rise to a large number of new technologies, new products, new applications, and new models.

China focuses on accelerating the transformation of its economic development model, pays more attention to the improvement of economic quality and people's living standards, and uses new generation information technology, including blockchain technology, to transform and upgrade traditional industries and enhance the competitiveness of traditional industries. Develop quality and efficiency, and improve the level of smart social management, public services and home life.

The huge market demand in the future will bring rare development opportunities and broad development space to blockchain technology. Researchers compiled and analyzed that China’s blockchain market will maintain rapid growth, with a compound annual growth rate of 73% in market size from 2021 to 2026. The market size in 2026 will reach US$16.368 billion, and in the next 20 years, China’s blockchain market will The industry market size is expected to reach the trillion level.

At present, the country also strongly supports the development of blockchain Technology is expected to be applied in various fields, so now some large companies, such as Tencent, Alibaba, NetEase, and the Internet are involved. It is still in the development stage, and we can look forward to the future

BlockchainThe economy cannot simply be understood as various virtual currencies. The essence of the blockchain is to solve the problem of authenticity, confidentiality and non-tampering of information. (Everyone participating is a recorder of information, and everyone is only a recorder of the entire information chain. (One Ring) It more effectively solves the problems of privacy and integrity, so its application scenarios and prospects are broad and promising. (But it should not become a paradise for scammers)

IV What is the use of blockchain besides Bitcoin

Virtual currency is not the only way out for blockchain. Here are a few already implemented and relatively common blockchain applications

Finance

Except for special applications like Bitcoin, in traditional finance In the industry, blockchain technology also has various emerging opportunities. Identity authentication, financial transactions, payment and settlement, and supply chain finance all have their application scenarios.

Because of the non-tamperability of blockchain technology, the trust in the financial industry has been further enhanced. Participants in the chain can query each other's information without having to establish connections through a centralized system. This not only improves work efficiency, but also reduces risks.

Games

The traditional online game industry almost always connects all users together through a server-centered star network. The responsibilities of the server include running applications, transmitting data, saving data and other functions. With the continuous increase of users and the continuous iteration of versions, the pressure on the server and the cost of enterprise investment are increasing day by day.

The distributed computing of blockchain allows each client to undertake certain computing and storage tasks, which not only reduces the pressure on the server, but also further improves data security. .

Electronic Contracts

Traditional paper contracts have disadvantages such as difficulty in confirming the signing identity, easy tampering and loss, and difficulty in management. With the development of the Internet, electronic contracts have played an important role in meeting corporate needs to improve efficiency and reduce costs.

The addition of blockchain technology makes electronic contracts more secure and reliable. Taking the Fada Electronic Contract as an example, through the "Fa Chain" alliance that cooperates with Microsoft (China) and Onchain, important digital fingerprint information on the electronic contract such as the signing time, signing subject, and file hash value of the Fada Electronic Contract will be It is broadcast to the respective nodes of all members. Once all information is stored, no party can tamper with it. At the same time, the hash value information of the file is also simultaneously stored in the national authoritative electronic data forensic identification center, which fully meets the requirements for judicial storage of electronic evidence.

Copyright

Although people's awareness of copyright is constantly increasing, with the increasing number of electronic devices and increasingly convenient data transmission, pirated products still belong to the creators. A piece of heart disease. What worries the original author even more than piracy is the series of disputes caused by the inability to confirm that he is the original author.

The addition of blockchain makes copyright confirmation more convenient. After the author completes the creation, he can register and store the certificate on the blockchain platform. This kind of time-stamped, non-tamperable certification document can give the creator a higher voice.

Logistics

Nowadays, there are many well-known products that are adulterated or replaced with other items during transportation. Traditional anti-counterfeiting signs have frequently shown a sense of powerlessness in today's world where criminals' technologies are becoming more and more comprehensive.

There are now some large companies that have applied blockchain to logistics and supply chains. Through technology that cannot modify data on a single node, the process in each transportation link will be traceable. There are already cross-border logistics companies in China, which have used this technology to achieve step-by-step traceability of overseas goods, international logistics and import declaration traceability, domestic logistics traceability, and even production enterprise traceability. Such an application will undoubtedly gradually increase consumer confidence and build brand authority.

I believe that in the future, this underlying technology will be used in more industries and scenarios.

IV What does blockchain mean and what are its main uses

In recent years, a hot word has appeared frequently on the Internet, that is "blockchain". This word gives people It’s a very noble and powerful feeling, but many people don’t know what blockchain means? And what are the main uses of blockchain? Let’s take a look at the relevant content that has been issued.

Blockchain Blockchain is actually equivalent to a disintermediated database, which is composed of a series of data blocks. Each of its data blocks contains information about a Bitcoin network transaction, which is used to verify the validity of its information and generate the next block. In other words, blockchain is essentially a decentralized database.

In a narrow sense, blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order, and uses cryptography to Guaranteed immutable and unforgeable distributed ledger. Broadly speaking, blockchain is actually a distributed infrastructure and computing method that is used to ensure the security of data transmission and access.

In addition, the blockchain is composed of six infrastructures: data layer, network layer, consensus layer, incentive layer, contract layer and application layer. Regarding its role, blockchain is mainly used to solve the trust and security issues of transactions. The above is the relevant content about the meaning and function of blockchain. I hope it can help friends in need.

VI Does blockchain have a future?

The concept of blockchain has been very popular recently. It is like the Internet in the 1990s, promising to completely change our world. Whole life, both professional and personal. Just as the Internet spawned thousands of new companies in its early days, so too is blockchain now.
As the backbone of emerging technologies, blockchain is not only used for virtualThe field of pseudo-currency is also being attempted in other fields such as finance, medical care, and intellectual property certification. A large number of outstanding companies have emerged at home and abroad to develop or enter the blockchain industry. Microsoft, IBM, Tencent, Alibaba, JPMorgan Chase, NetEase, Xiaomi, etc. have all deployed blockchain. In the past two years, blockchain will flourish in many fields.
It can be seen that blockchain technology is developing rapidly in the world. Perhaps in the next few years, blockchain-related technologies will be applied to the intelligent field and the notarization field, including identity information authentication, notarization, arbitration, auditing, email, personal visas, ticket information, etc. The scope of application can be Covering the entire society, blockchain technology has the potential to become the lowest level protocol for the Internet of Everything.

VII What effect does blockchain have on real life

Blockchain is essentially a disintermediated database that uses a blockchain data structure to verify and store Data, a new distributed infrastructure that uses distributed node consensus algorithms to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses smart contracts composed of automated script codes to program and operate data. and calculation methods. In layman's terms, blockchain is a distributed accounting technology, which has the characteristics of decentralization, non-tampering, and node consensus mechanism. Although it sounds a bit obscure, it can actually bring tangible benefits to our daily lives:
First, blockchain technology can be used to establish a traceability mechanism for food and vegetables, completely eliminating source pollution of food and vegetables, and providing the common people with Safe and hygienic green food and vegetables allow everyone to buy and eat with confidence;
Second, blockchain technology can be used to store various ownership certificates and notes and transcripts, completely eliminating fake certificates, fake files, fake academic records, fake medical records, fake transcripts, etc. Fraudulent incidents occur;
Third, blockchain technology can be used to conduct community election voting, completely eliminating fake votes and truly achieving openness, fairness and impartiality. Build a democratic community and achieve democratic governance.
In addition, blockchain technology can also be used in many aspects of daily life such as charity fundraising and commodity anti-counterfeiting.

ⅧWhat exactly is blockchain and what are its uses

Recently, the word "blockchain" has appeared very frequently on the Internet. The word "blockchain" is very interesting. So what is "blockchain", how to explain "blockchain", and what kind of chain is "blockchain"?

If we want to know what “blockchain” is, we must first start with Satoshi Nakamoto.

In November 2008, Satoshi Nakamoto posted a research report on a secret cryptography review group, describing his new idea for electronic currency-Satoshi Nakamoto proposed : "I believe there is a currency that doesn't rely on credit, and I can't stop myself from thinking about it." Bitcoin was born.

Although we still don’t know who Satoshi Nakamoto is, we all know the famous nameDing’s Bitcoin, and also knows the recently popular word “blockchain”.

In professional terms, blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc.

In the original English version of the Bitcoin white paper [2], the word blockchain does not actually appear, but chain of blocks is used. In the earliest Chinese translation of the Bitcoin white paper [3], chain of blocks was translated into blockchain.

What does it mean in human terms? In layman's terms, blockchain is a decentralized distributed ledger database.

Decentralization means removing the original data center.

Here is an example of decentralization: Alibaba’s servers support Alibaba’s daily data operations, including the Double Eleven that just passed. We were able to smoothly carry out flash sales of goods at zero o’clock. Largely thanks to the support of Alibaba servers.

All data generated by Alibaba’s daily activities are recorded on the server. So what will happen if Alibaba’s server encounters an accident? (For example, Alibaba's server was hit by a meteorite, causing the server to be damaged)

After the server is paralyzed, Alibaba's data will naturally be unable to be restored in time, which will result in Alibaba being unable to maintain daily operations in the short term. operations.

However, after adopting blockchain technology, a piece of data generated by Alibaba due to daily business will not only be recorded on Alibaba’s servers, but also on various servers around the world such as the Internet and Google. In this way, even if Alibaba's servers encounter an accident, it will still not affect Alibaba's operation. The data generated by Alibaba's daily activities will still be recorded on various servers around the world. This is the advantage and benefit brought by blockchain technology.

In other words, Ali's data was only recorded in Ali's server, and Ali's server was the center. Now every server in the world is synchronously recording the business that Ali has done, and Ali's server is the center. It is no longer the only center, this step achieves decentralization. The behavior of servers around the world recording Alibaba data simultaneously is called distributed accounting.

Now that we know what blockchain means, what kind of boundaries can blockchain bring to our lives? What fields may blockchain be used in in the future?

1. Blockchain technology is applied in the medical and health field. For example, Xiao Zhang’s family has a history of hereditary red-green color blindness. Xiao Zhang once went to Hospital A and had his red-green color blindness checked. Now Xiao Zhang is in City B and went to Hospital B for treatment. Now Hospital B can directly treat him in his own hospital. Xiao Zhang’s previous medical treatment status was found in the database, and Hospital B does not need toA repeat inspection was done on Xiao Zhang. This greatly saves medical resources for the hospital and saves medical expenses for repeated examinations for Xiao Zhang.

2. Blockchain technology is applied in the field of food safety. Nowadays, everyone is paying attention to food safety, and blockchain technology is applied to the field of food safety to carry out food traceability. First, we can label each vegetable and fruit with its own label, and then record the growth, maturity, pests and diseases of the vegetables and fruits in this label. The data in this tag can be simultaneously recorded in various data centers around the world through blockchain technology.

On the one hand, when people buy vegetables, they can directly check the growth status of the vegetables. On the other hand, when our country imports and exports vegetables, we can directly check the status of the imported and exported products. No more quarantine required.

Ⅸ Is the blockchain now in the limelight and has no future?

Blockchain is in the limelight, no, right? Blockchain technology has been developing and it has no future. Not quite right.
The current development of blockchain is still OK. Here are a few recent examples: On June 14, led by the Information Center of the High People’s Court and co-sponsored by a total of 25 units, the “Blockchain Judicial Certificate Deposit” was launched. "Application White Paper" was officially released, and blockchain technology has already achieved results in the field of judicial evidence; VISA recently launched a blockchain payment network and entered the US$125 trillion cross-border payment market; Fuzhou City also recently issued "About Acceleration Three Measures for the Development of the Blockchain Industry" to promote the implementation of blockchain technology applications.
Further further, there are blockchain electronic invoices, blockchain traceability, etc. I won’t talk about these, so there is no future for this one. Crypto Finance focuses on blockchain, you can learn more here.
