❶ Is 2022 a good time to buy a house? Do you have any plans to buy a house?

First of all, there is no telling what will happen to China’s housing prices in the future.

Overall, in the next 2-5 years, the first and second tiers will fall by 15%, and the third and fourth tiers will drop by 30%. It is a high probability event. The first and second tiers have low holding costs, while the third and fourth tiers have limited purchasing power.

Nowadays, the leverage of residents is too high, and it is difficult for the state to increase wages even if they release funds. Basically, they are transferred to Leeks in the form of leveraged credit. The current situation is really unbearable. In the past few years, almost everyone who has enough basic money to make a down payment has bought a car. It is really dangerous to double the down payment.

Do the third and fourth tiers want to sell land? Of course they do. Is there a shortage of land? There is certainly no shortage. The new areas are all filled with land. The key is that this liability is not transferred to home buyers, and the government's land sales money is the bank's money. Again, there are too many stocks and I really can’t pick up the leeks. Recently, there have been more and more failed land auctions, and it is urgent to supplement finance with property taxes.

The essence of the first and second lines is the same, but the situation is slightly better, because the belief and holding cost are too low, and the two sides are still in a stalemate. Shenzhen and Shanghai restricted loan quotas, transaction volume dropped instantly, and the so-called big guys who bought the houses they just needed with full payment disappeared.

The introduction of the property tax has completely changed this equilibrium state. The guide price is obviously prepared for the property tax. Otherwise, who else would be so tired to give a guide price to each community. If the real estate tax pilot is implemented quickly, it will be by the end of the year. If it is slow, it will be next year. It will definitely be launched. It will not be as harsh as everyone thinks, and it will not be like Shanghai and Chongqing before. Sell ​​the land when it is time to do so without delaying property taxes. After all, there will be a transition time, and the ratio between the two will be dynamically adjusted. At the same time, state-owned developers began to develop public rental housing. The country has many options for building public rental housing: a large number of vacant office buildings in the city center have been renovated, have good locations, and are endorsed by the state. It just depends on whether the country is willing or not. As the holding cost goes up, first-line housing prices will definitely loosen, but after all, if the first-line housing prices decline for a few years, a 15% drop is acceptable, and it will just go back to around 2019. So I personally feel that the first and second tiers will be an excellent low point to get started in 2-3 years.

It is estimated that it will take 2-3 years before the third and fourth tiers are fully levied, but if we have expectations, we will not be afraid of rising prices. The bubble in the third and fourth tiers is still quite serious. A 30% drop is considered good, but it may be cut in half directly.

This time we look at the determination and means to deal with double reductions. It feels really different.

Finally, no matter whether you buy it or not, just pay attention to the leverage. Yesterday I saw a post about buying a house in Chengdu, draining the down payment of both parents and borrowing foreign debt. It's so dangerous. Many people born in the 1990s have not realized that their parents' bodies are getting weaker day by day, and people will get sick as they get older. Being sick costs a lot of energy and money.

❷ What is the future development trend of blockchain?

Major companies in the industry: Ping An of China (601318), Donggang Co., Ltd. (002117), Information Development (300469), Yuanguang Software (002063) ), Boss Software (300525), Feitian Integrity (300386), Sifang Jinchuang (300468), Industrial and Commercial Bank of China (601398), SF Holding (002352)

The core data of this article: the number of Chinese government blockchain tenders, Chinese government districts Types of blockchain bidding

my country's blockchain market has maintained a high growth rate

From 2016 to 2018, large IT Internet companies have deployed blockchain, and start-ups have entered a blowout mode. The scale of the industry continues to expand. According to IDC 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%.

From a year perspective, from 2016 to 2020, the number of government tenders for blockchain-related projects has been growing exponentially. On the one hand, it benefits from the increasingly prominent application value of blockchain technology. On the other hand, it also reflects that the government’s demand for and emphasis on blockchain has increased.

Tendering projects are mostly concentrated in the second half of the year

Judging from the release time of tenders and tenders over the years, the time for the government to issue tender announcements for blockchain-related projects is concentrated in the second half of the year, especially from September to December In September, more than 50% of government blockchain projects issued bidding announcements from September to December. This reflects that the government is more cautious in project decision-making and has a more systematic project promotion process. It usually discusses and formulates annual work plans at the beginning of the year, conducts project approval after the two sessions, and starts to focus on bidding and construction after July.

The Beijing Municipal Government has the most blockchain bidding projects

From the regional distribution of bidding units, from 2016 to 2020, the government and scientific research institutions participating in blockchain project bidding Covering more and more provinces, government departments in 10 provinces issued blockchain project bidding announcements from 2016 to 2019, and 8 new provinces were added in 2020. Judging from the number of tenders, the governments and scientific research institutions in Beijing and Guangdong are relatively active, and the total number of tender projects ranks among the top. The reason is that the two places have a good foundation for development, with a concentration of universities and scientific research institutes. They are both pioneers in my country's reform and opening up and the vanguard of information technology innovation. Compared with other regions, the government has greater demand for blockchain innovation.

The number of application development projects is growing rapidly

Among the 113 projects released by the government, each project has its own focus and can be roughly divided into application development and related facilities procurement ( There are four categories: laboratory equipment procurement, experimental platform construction, etc.), technical research, and others (feasibility analysis, development strategy consulting, etc.). Judging from the changes in the number of bidding projects, bidding projects for blockchain application development are growing rapidly.

Taken together, as my country’s blockchain technology continues to mature, blockchain-related applications are being used in various industries.The implementation process of the industry is gradually accelerating.

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

❹ Research on the new construction project budget platform

Project budget is a very important work item in the management of construction engineering enterprises. At the same time, in the process of engineering construction, the project budget is an important part of the construction project. is very important and requires extremely detailed work. Since the influencing factors of this work will cover a very wide range, how to reduce the influencing factors will be an important research direction in the future of project construction quality and funding. With the continuous in-depth research on blockchain technology, based on the important characteristics of blockchain technology, the establishment of a new blockchain engineering calculation platform will inevitably become the development trend of the future industry, reducing errors in project budget estimates, reducing deviations and even Eliminate the influence of other hidden risk factors.
The project budget is a foreseeable calculation of the overall income and expenditure of the overall construction project in a certain period of time in the future. The measurement unit of the project budget is in the form of currency. Therefore, through the normal income and expenditure of currency, we can evaluate the economic value of the project based on the overall budget results, and even strengthen the management, economic accounting and cost assessment of the enterprise. It must be referred to and considered. Of course, when bidding for construction projects, budget is also one of the most important basis for determining the quotation and overall project cost. It can be seen that the project budget is of vital significance in the construction of construction projects. At present, the budget budget mainly faces three major problems.
1) The influence of human factors: Although engineering budget software such as Glodon has long been an essential calculation software in engineering budgets, manual calculations are still included, and errors will inevitably exist. In addition, malicious competition or malicious competition may occur. Incidents where data loss eventually destroys calculation results occasionally occur. The loss of these calculation results not only loses the hard work and crystallization of the estimator, but may even directly affect the bidding results, and even affect the construction schedule and project quality. 2) Loss of stored data. Previous calculation results basically required triple backup, but in the face of emergencies, it is still possible to lose all calculation results, including the influence of subjective factors or objective factors, such as man-made destruction, natural disasters, and natural losses. How to ensure data It exists permanently and cannot be modified without authorization. This is also an issue that needs to be solved urgently in the project budget.
3) Work allocation. The traditional project budget work allocation is based on step-by-step calculations of individual projects such as steel bars, concrete, prefabricated panels, and labor costs. It is prone to omissions, miscalculations, etc. If a one-step calculation error is not discovered in time, a large number of inquiries will be made later. After checking the data, overturning and recalculating, all the calculation efforts of one or even multiple people will be wasted. FollowWith the rapid advancement of technology, the emergence of blockchain technology seems to be able to perfectly solve many "difficulties" existing in past project budgets. The so-called blockchain is a new application model that includes distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies [1]. Its essence is decentralization. Take the project budget as an example. In the past, a complete project construction budget was calculated manually by the estimator using the software, and then calculated and summarized by the budget engineer, and finally the project cost manager. The person in charge will make the final calculation and sign for confirmation.
The procedures are complicated, the time span is long, and omissions are easy to occur. However, if the blockchain technology platform is embedded, the entire construction project is assumed to be an "engineering chain". Based on the peer-to-peer transmission of blockchain technology, the budget clerk can directly The final confirmed results are loaded into the entire project chain as modules. Through the consensus mechanism, each budgeter on the project chain serves as a node. The calculations under the consensus mechanism can reduce the probability of calculation errors and avoid human error. to change the calculation results. So how can a completed "project construction blockchain" solve various problems that arise in the project budget? Through research, we found that we can build such a blockchain login platform by using the consensus mechanism of blockchain technology and distributed storage of data. Solve many problems and hidden dangers in the construction of engineering projects.
1 Use the consensus mechanism to solve the trust crisis
The distributed ledger technology applied in the blockchain can build a visibility organization to ensure that the data is not changed. Therefore it is very transparent and trustworthy. Blockchain provides a permanent record and data storage that is immutable. The characteristics of blockchain, which cannot be tampered with and are completely open and transparent, are the first impression of this new technology for everyone who comes into contact with it [4]. In the construction of construction projects, many budget projects have relevant data in different specific sub-projects. In the past, data could not be shared between different projects. It must be consolidated and recalculated by the final estimator, although the application of software has been widely popular [3].
However, in the actual application process, such problems cannot be avoided. Due to the lack of artificial intelligence integration, all calculation data are not centered on the project, but on the estimator as the center of the calculation results, with fragmentation The method exists and is stored in the hands of different estimators, which is equivalent to a small database. Such "small database" needs to be converted and moved again to the medium-sized database of the estimator, and finally completely summarized into the large database of the general project. , such a step-by-step calculation and transmission process is not only to avoid errors, but also to ensure the trustworthiness of the data. However, the original good intentions are no longer appropriate after the emergence of new technologies. Using the consensus mechanism of the blockchain can completely solve the problem of human modification and impact on data, because the data cannot be tampered with and is completely open to the public. It is transparent and uses its distributed storage characteristics to completely avoid problems in the entire operation caused by personal mistakes. untieResolve the trust crisis and potential human influence in the project budget.
2Use "smart contracts" to provide construction guarantee and work allocation for engineering projects
What is a "smart contract"? A simple example is given: When a developer builds a building, there may be more than 10,000 contracts, which are subcontracted by the general contractor and several levels of contractors. However, when the general contractor receives the money, how can we ensure that the other contractors at all levels will get the money? This requires the protection of blockchain. "The smart contract will write in the code what action to perform under what conditions. Put this contract on the blockchain and no one can change it. As long as the general contractor receives the money, subsequent transfers will automatically start [ 5]." In the same way, if this "smart contract" is applied to the estimated budget of an engineering construction project, only when the first-level budget is confirmed and preparations begin, the smart contract will take effect and the next step will be executed. Calculation not only ensures the entire operation of the calculation process, but also ensures the complicated correction procedures and verification process after the project is completed. What the engineering project blockchain needs to do is to provide a very comprehensive and complete data for all engineering project participants, and to provide personalized specific project implementation details with the entire project as the center, so that the engineering construction project can automatically determine the next step. To whom execution information is shared [6]. Once you have this comprehensive database, the efficiency and overall security of engineering construction projects can be completely improved.
3 "Blockchain + Engineering" makes use of data storage
Centralizes fragmented engineering construction budget data to help budgeters and chief engineers make decisions based on more sufficient basis and provide engineering projects with More comprehensive engineering project construction advice. This is the application prospect of blockchain in the field of engineering and construction [2]. For "computational security," blockchain can also play a role. Using the traceability function of the blockchain, full chain traceability can be achieved throughout the entire budgeter's computing supply chain, thereby ensuring the security of data storage. The budget data supply chain is the lifeblood of engineering enterprises. The scientific management of the budget data supply chain can add a protection lock to the data security of engineering construction projects. The distributed and peer-to-peer characteristics of blockchain are very suitable for engineering and construction projects. The purpose of introducing blockchain technology into engineering projects is to achieve the "separation of three powers" of data - to determine the relationship between the "owner", "user" and "executor" of data, in line with the country's standardized management and use of data. It can also meet the industry’s openness and transparency needs in data applications.
Through blockchain, a new platform can be created for Internet-based services. "Blockchain + engineering construction" can make the construction of engineering projects more and more safe and reliable. At the same time, based on blockchain, data sharing can be promoted and a trustworthy system can be built. Combining the two with Internet services can even build a new platform. Today, with the diversification of data storage technologies, various technologies bring various security risks, and the engineering construction projects themselves involve very huge funds., the problem of human corruption is particularly serious. Various types of problems such as changing data and erasing data often occur during the project budgeting stage. This has become one of the common topics in the industry. Once blockchain is implemented, all projects will The project data will be open, transparent and cannot be tampered with. Whether it is the person responsible for the project itself or the person responsible for all budget estimates, it is necessary to carry out a lifelong responsibility system for the entire project, that is, to solve the fundamental problems technically and solve the People's psychological luck mentality ultimately ensures the convenience, practicality and safe storage of data.
A certain city office building, a complex large-scale public construction project, the total cost of the building is about 1 billion yuan, the estimated budget of this construction project needs to be calculated before bidding, the total project list of this building is estimated At about 2,000 items, it is estimated that a company with an average cost budget of about 10 people will need 7 days to 10 days to carry out the project. However, it will still be affected by many factors, such as artificial influence. In recent years, the market has changed greatly, and labor The impact on rates is also very different. Taking the Beijing-Tianjin-Hebei region as an example, the daily difference for a single work station is often dozens of yuan. Secondly, the difference between Beijing and Tianjin is that Tianjin is divided into Category I workers, Category II workers, and Category III workers. Then there are environmental differences. For example, in hydropower projects, there is a huge gap between the north and the south, which also needs to be considered; the difference in construction sequence also directly affects the construction of the overall building project.
Influencing factors such as these may bring about price fluctuations in engineering budget projects at any time, and such price fluctuations directly lead to the differentiation of budget projects. If such budget projects use blockchain technology The platform re-budgets only requires 5 people and can be easily completed in 4 days to 6 days. Moreover, based on the platform's internal AI, 3 calculation project results can be obtained using 3 data, namely peak data, average data and underestimated data, and then you can choose to calculate Submit and declare the results, and respond to possible influencing factors at any time. While the efficiency has been improved by more than 50%, it can almost avoid the existence of influencing factors, which will lead to fluctuations in the results of budget projects. At the same time, the permanent distributed storage, artificial intelligence technology, consensus mechanism and other technologies of the blockchain platform are borrowed to make the results of the project budget estimate more accurate and perfect. It is worth mentioning that in this study, we need to rethink how to "reshape" the construction industry with the various technical services that appear in life. In particular, technologies such as artificial intelligence and 5G can be used to add trusted systems and data sharing to the construction of engineering projects, thereby improving the level and efficiency of project construction. In the future, blockchain should focus on three aspects.

❺ How to define blockchain What are the application scenarios of blockchain

Many people now think that blockchain is a universal technology that can do anything.It’s a bit of a myth about blockchain technology!
Regarding the definition of blockchain technology, American scholar Melanie Swann defined blockchain technology as an open, transparent and decentralized technology in her book "Blockchain: A New Economic Blueprint and Introduction" database.

Definition of Blockchain: Narrow VS Broad

As for the application scenarios of blockchain technology, it is natural to combine the differences between blockchain and other technologies. In terms of system characteristics.

Blockchain technology features include:

Blockchain is a global A database storage system that can be operated collaboratively in various places is different from traditional database operations where read and write permissions are in the hands of a company or a centralized authority (a characteristic of centralization). Blockchain believes that anyone with the ability to set up a server can participate. Nuggets from all over the world have deployed their own servers locally and connected to the blockchain network to become a node in this distributed database storage system; once joined, the node enjoys exactly the same rights as all other nodes and obligations (decentralized, distributed characteristics).

At the same time, people who provide services on the blockchain can perform read and write operations on any node in the system. In the end, all nodes around the world will complete the process again and again according to a certain mechanism. Synchronize in sequence to achieve complete consistency of data in all nodes in the blockchain network.

At the beginning of this year, the term blockchain began to enter everyone’s lives. From national leaders to aunts who dance square dances, everyone knows this term. This term is widely known by Bit Brought by coins.

As we all know, the first few dozen bitcoins could only be exchanged for one pizza. At its peak, it was more than 20,000 US dollars each, which has skyrocketed by more than a thousand times, which has also benefited a large number of wealthy people. Currently, there are blockchain The virtual currency generated by technology is gradually entering into everyone's life, and many people have joined the ranks of currency speculation. I often hear people say that if you buy the right currency a hundred times, a bicycle will become a sports car, and one coin will turn a young model. You can imagine how many of them are involved. Attractive.

Since 2008, various games applying blockchain technology have also become popular, such as development games (Network Letts Dog, 360 Block Cat), mining games (NetEase Planet, Virtual Earth, Gongxinbao), these are attracting everyone to join in the name of blockchain, and of course there are some that are really reliable, which requires everyone to identify them carefully.

The three words "blockchain" were completely ignited during the Spring Festival that just passed, and the limelight overshadowed everything else. Some people said that this was the arrival of a new era, and the past has become classic, while others said To say that everything is hype is ultimately a bubble.

In fact, blockchain technology is not a new concept.In the past two years, it has begun to be applied in many industries, such as electronic signatures. Recently, the third-party electronic signature platform eShanbao revealed the latest progress of blockchain applications to NewSeed.

Currently, blockchain technology is mainly used in e-signing products for certificate deposit and certificate issuance. The application scenarios include copyright protection and online signing. , web page forensics, phone recording, email storage of evidence, etc.

Take the rights protection of online works as an example. Since online rights protection generally adopts the method of collecting evidence after the fact, real-time confirmation of rights is not carried out in the process of evidence generation, so the entire confirmation process is difficult. The copyright process is time-consuming, difficult and costly to obtain evidence, and extremely difficult to prove and trace the source. It cannot meet the characteristics of rapid dissemination and large quantity of online works.

eShanbao's new intellectual property protection solution based on timestamp + blockchain starts from the user's real-name authentication and solidifies the information generated in the process in real time. Electronic data, and through the time source service synchronized with the National Time Service Center, online works are stamped with legally valid timestamps to prove that electronic files have not been tampered with in a certain period of time. Blockchain technology can establish point-to-point trust in the network, ensuring that all blockchain nodes can record complete copyright confirmation and transaction records, and can trace their origins, truly realizing anti-repudiation and anti-tampering, and realizing a kind of distribution. trust infrastructure.

Founder and CEO Jin Hongzhou believes that the application of decentralized blockchain technology has greatly improved the efficiency of data storage and certification, and The credibility of the identity of the parties reduces the cost of trust, but it cannot replace the original centralized public key encryption technology. The two should complement each other. Through the combination of the two, it can provide users with real-time and reliable Confirmation plan.

Next, e-Shanbao will also focus on building a smart contract platform based on blockchain technology. Jin Hongzhou said that data storage, Issuing certificates is only a relatively superficial application based on blockchain technology. It is the first step to implement blockchain technology, and the realization of real smart contracts is the second step. "Smart contracts cannot simply be understood as electronic contracts. They refer to a process, from the conclusion of the contract to the confirmation to the final execution." Jin Hongzhou explained.

Through the following limited cases, I hope everyone can understand the actual performance of blockchain technology, thereby stimulating interest in such solutions.

1. Administrative Services

Over the centuries, the roles and responsibilities of public administration have not changed significantly – or rather, what has changed dramatically is actually the size of the data and the specific ways in which public agencies handle it. Although there are currently various types of tools that help collect and processData digitization technology, but problems such as anonymization, portability and the immutability of large amounts of data have still not been solved.

Sasha Ivanov, founder, entrepreneur and CEO of Waves Platform and Vostok projects, said, "What the public administration currently lacks is a more convenient user experience (UX) for data use. To improve the user experience , we should introduce some kind of layer to it that acts as a trusted public environment that is transparent and can store data anonymously and immutably."

Governments are working on this by launching the U.S. Federal agency and enterprise-level initiatives such as the Federal Blockchain Initiative are gradually confronting the existence of such problems. The United States held its first federal government blockchain forum in July 2017, and the U.S. General Services Administration currently has more than 200 related use case repositories. Ivanov explained, “Distributed systems can really help us build such a reliable environment, improve our big data work, and even integrate all emerging technologies – including artificial intelligence and the Internet of Things. In fact, , whenever we face any kind of technology, it always embodies the sum of certain other technologies."

Now, the system supported by the blockchain can actually work - this This view has been unanimously recognized by all experts and has become the most important theoretical basis. In other words, what we need to do next is create more production-ready solutions.

2. Payment services

The government needs to process transactions, many of which involve the exchange of funds with citizens. Blockchain technology has huge potential application value in reducing the cost of fund transfers - including using new blockchain-based cryptocurrencies as intermediate transaction carriers, or using blockchain as a means of fund transfer, etc. Once a perfect solution is discovered, the business opportunities will be endless - especially for those who need to conduct frequent cross-border or Internet transactions.

The Jasper project was developed by the Bank of Canada to help it further think about how central banks and other financial institutions should implement payment operations between different banks based on distributed ledgers. The Bank of Canada has also developed its own digital currency variant, “CAD Coin,” to test the feasibility of using a national currency on top of the blockchain.

This project brings to an interesting conclusion that we should say no to proof-of-work public chain systems. In a paper titled "Project Jasper: Is a Distributed Batch Payment System Feasible?" the author observed that "Proof-of-work systems are not suitable for such large transaction processing systems because they assume that all transactions in the system are There is a need for openness and observability to a certain extent.”

3. Digitization and intellectual property

Governments have the responsibility to maintain copyright records and databases. These records prove ownership of intellectual property. A blockchain-based system would allow artists, performers and writers of all kinds to time-stamp their works and theoretically detect copyright infringements and even keep a permanent record of their rights. In fact, many governments have already taken important exploratory steps in this direction.

Iran recently announced that it will deploy this technology. "Iran Financial Tribune" quoted Morteza Mousavian as saying that "the Digital Media Department of the Ministry of Culture has reached an agreement with a blockchain company to jointly design a system that can be used to protect online copyrights." He also added that "the relevant procedures will It will soon be released to users in an easy-to-use format."

This work is still in the early exploratory stages, but it offers enterprise customers the possibility of preserving records through replication technology. From a theoretical level, companies can use blockchain solutions to conduct financial accounting and discover errors in real time.

4. Welfare distribution

The government has the responsibility to create a level playing field for citizens. Citizens who are chronically poor or economically disadvantaged certainly need government support and assistance to ensure that they are able to sustain themselves and develop. However, welfare distribution is neither simple nor often straightforward. Problems such as corruption and impersonation have been wreaking havoc on various distribution channels within government schemes.

In China, the National Council of Social Security Fund is conducting early research on how to use blockchain technology to improve the delivery of national benefits to citizens. At the same time, India is also taking action. Andhra Pradesh and Telangana are already using blockchain to support their civilian resource supply systems.

It is said that many companies, including Microsoft, are also considering using the same technology. These solutions, which will touch individual employees and functional roles, are expected to gradually appear in small businesses in the near future.

5. Bidding activities

In order to build public infrastructure or provide related services, the government hopes to achieve economies of scale and competitive gains through bidding as much as possible. However, the bidding process is often not fair or transparent. Public procurement has long been a major scene of rampant corruption around the world. Transparency International noted that “many governments will award project contracts to a certain supplier in the absence of fair competition. This allows companies with greater political resources to improperly win over competitors; or companies in the same industry Bids will be negotiated in advance between companies, ensuring that each company gets a share of the tender. This will significantly increase the cost of delivering services to the public - we have found that corruption issues can increase project costs by 50%."

So, how can blockchain technology solve the bidding problem? According to Ivanov,“Unlike decentralized centralized systems, independent ledgers powered by blockchain will improve the transparency of tenders or any other financial process that needs to be tracked. The intervention of blockchain technology will help track the use of funds. , and ensure that it is paid as expected and within the allowed time.”

Currently, Japan’s Ministry of Interior and Communications has announced a blockchain-based bidding system, which means that in areas with serious collusion problems In the industry, small and medium-sized enterprises are expected to usher in a more transparent bidding method and brighter development prospects.

Although quite a few of the cases mentioned previously are far from finalized, they do provide many possibilities for companies and governments. Of course, the key lies in implementation; and we should also look at all this with optimism, that is, although blockchain technology is often misunderstood, it is and will eventually find a direction in which it can exert its own energy!

< p> In layman's terms, the blockchain is like a dozen beacon towers on the Great Wall. If an enemy comes at one place, they will send out smoke. The other beacon towers will know about it and enter a defensive state together. In technical language, it is a distributed ledger. Each node keeps accounts separately. The failure of one or two nodes will not affect the entire network.

How is this distributed network different from the distributed servers of Google Network? Google Network's distributed servers still belong to Google Network and are controlled by their central scheduling algorithm. The distributed nodes in the blockchain do not know each other and have no legal relationship. You can just go offline and shut down if you want, but because of the currency rewards, there will always be someone who will turn on the machine as a new node to support the network.

After the popular and technical explanation, I hope you understand. So the first application scenario is finance. I put my money in Alipay. If Alipay doesn't recognize it one day, there's nothing you can do. But on the blockchain, it is useless if one node does not acknowledge it, because other nodes still have my records. The second is the contract. Nowadays, contracts are made on paper and are easy to be faked. But if they are put on the blockchain, they cannot be faked.

There are more application scenarios. It is recommended to check the top 100 digital Huobi online to understand the corresponding projects behind them and become a blockchain expert. .

Blockchain technology was first used in Bitcoin. Blockchain provides a reliable and trustworthy means of organizing data for cross-subject business scenarios. JD.com is essentially a supply chain company, and blockchain technology will be first used in many scenarios of the supply chain.

Blockchain is a decentralized technology. Blockchain can be applied to all products currently covered by the Internet.

The most popular application industry at present is the financial industry.

The application that has been implemented is product traceability.Lihe JD.com is already using blockchain technology to fully trace the origin of some of the goods it sells. Consumers can trace the origin of the purchased goods. There are also many blockchain applications in the digital advertising industry. Since traffic fraud in digital advertising causes losses of tens of billions of dollars every year, there are already blockchain application projects based on digital advertising, such as DCAD, which is based on blockchain. The digital advertising application of blockchain technology mainly solves the problem of traffic fraud

In the future, as the application of blockchain technology becomes more mature, it will be applied in many industries, creating a new ecosystem based on technological trust. Mode

The characteristics of blockchain are distributed accounting and decentralization, but the ultimate goal is to make people get along more equally. Technology is meaningful only when it serves human values, and technology that meets human value needs will develop. Therefore, blockchain is in line with human pursuit of freedom and equality, so its trend to become mainstream is unstoppable.

Currently, there are many blockchain gimmicks, which are basically used to issue coins. The newly launched ono is a decentralized, free and global social platform. Due to decentralization, your chat communication information is peer-to-peer and cannot be viewed by others. In other words, your every word and deed will no longer be recorded and reviewed at any time like it is now on WeChat, QQ, and Facebook, freeing you from the trouble of surveillance.

In fact, blockchain technology can be used in any field. Information that previously required third-party confirmation can be completed online and confirmed at multiple nodes, making it difficult (almost impossible) to delete.

At present, blockchain is still in its infancy, and the technology is not mature enough, but it is also a better time to enter.

What is blockchain

If you use non-technical terms to explain blockchain, blockchain is a place where data is stored. However, the data stored in the blockchain is safe and reliable and does not need to be managed by anyone, so In the Internet, a place where data and information are exploding, having such a place would be like a magical treasure.

What can the blockchain do?

If you ask what the blockchain can do, it is better to say what applications require the use of the blockchain. As mentioned earlier, blockchain is a safe place, so wherever data needs to be protected securely on the Internet, blockchain technology needs to be used. For example:

Because the use of blockchain technology can better protect the data of policyholders, in today’s Internet, data is value and wealth, so value protection and value transmission are the future development directions of the Internet. And blockchain technology can really do just that.

If there are any deficiencies, you are welcome to comment and correct me.

In a narrow sense, blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable and non-tamperable. fakeCreated distributed ledger.

The two parties involved in the transaction do not need to know who the other party is, nor do they need a third party for trust endorsement. They only need to trust a common algorithm to establish mutual trust and conduct direct transactions.

Its characteristics are trustlessness and decentralization. The destruction of each node's ledger has no impact on the entire blockchain. The blockchain runs point-to-point payments without a center that may cheat, and the security is greatly improved. Improved, the entire transaction network has changed from a star structure to a point-to-point P2P structure.

In the future, blockchain will be used in many fields and will have a great impact on human life. . It can be widely used in fields ranging from digital currency to securities and financial contracts, medical care, games, artificial intelligence, smart contracts, Internet of Things, e-commerce, file storage and other fields.

1. Cloud storage

This is the statistics of current cloud storage on the Internet. In terms of volume, Google has the largest volume, which is 8,000PB. So what if we share the idle data on the Internet?

Starlight Cloud builds a blockchain data computing and storage lake through Starlight Chain, with a total storage capacity of 15,000P (approximately 15.72864 billion G) in the future. This will be more than 10 times that of Alibaba Cloud's 1500PB! It is also more than four times the size of the Taizhou Storage Center, the largest storage lake in the world after expansion.

2. Medical aspects

Using blockchain technology to save personal medical records also retains personal medical historical data, which can be used when seeing a doctor or planning for your own health in the future. Historical data can be called directly. These data are highly private, and the use of blockchain technology also helps protect patient privacy.

❻ What role can blockchain technology play in practicing ESG?

Take the blockchain company Qulian Technology as an example. Qulian Technology is driven by the dual-wheel drive of technological empowerment and strategic investment on the road to practicing ESG. It continues to require itself with the ESG evaluation system, and through technical support and investment, it supports the application of ESG at the micro level to be more practical. .
The COVID-19 epidemic broke out in early 2020.

❼ A brief analysis of the application of blockchain technology

Today we will talk about the application analysis of blockchain technology in the field of public resource transactions< br />Public resource transactions include both the purchase of public resources by the public sector, such as government procurement, construction project bidding, etc.; and the sale of public resources by the public sector, such as the bidding, auction and listing of state-owned land, the transfer of mining rights, The sale of state-owned forest rights, the disposal of state-owned financial assets and other public resource sales involving public interests and public security. Public resource transactions are related to the national economy and people's livelihood, and involve the fundamental interests of the people. Therefore, public resource transaction management has always been an important management function of my country's government affairs management.
In recent years, the National Information Center has continued to promote the construction of a public resource trading service platform, giving full play to the role of a public entrance to trading services, a public channel for data sharing, and comprehensive technical support for cross-regional transactions. The integration of public resource trading platforms based on digital technology has achieved remarkable results. Among them, blockchain technology has the characteristics of consistent data storage, difficulty in tampering, and traceability. It provides new ideas and solutions to solve the problem of trust in public resource trading data. path.

Information data management issues in the field of public resource transactions

Objectively speaking, various credit deficiencies have long existed in the field of public resource transactions in my country, which not only disrupts the normal market transaction order, but also It affects the fairness and justice of market competition, and also poses serious risks and threats to the quality of project construction and construction safety production. The reason is that the root cause of credit risk lies in the information asymmetry between entities in the public resource trading market, and in the limitations and defects of traditional public resource trading management on information data security and information data use.

Data security management issues

Various transaction information and credit information in the field of public resource transactions contain huge value. Under the increasingly electronic development trend of domestic public resource transaction management and services, including electronic bidding user identity information, potential bidder information, bid evaluation committee composition information, bid document information, judges' bid evaluation information, and bid evaluation result information Various types of information security risks have increasingly become important issues affecting the efficiency, quality, and fairness of public resource transactions.
Traditional data security technology cannot effectively avoid security management problems such as leakage, tampering, and loss of various information data. Especially with some technical means, it is difficult to trace traces of relevant data operations, causing great trouble for data security management. .
Data sharing application issues
The main reason for the long-standing problems of various credit deficiencies and untrustworthy behaviors in the public resource trading market is that there are limitations in the sharing and application of relevant credit information of market entities.
On the one hand, a large amount of credit information of market entities has been deposited in theWithin each department, it has not been fully explored and utilized;
On the other hand, the credit information of public resource trading market entities involves many management departments such as banks, public security, courts, housing construction, human resources and social security, taxation, etc., and long-term information between different management departments The existing phenomena of "data islands" and "data fog islands" hinder the efficient sharing and application of credit information in the public resource trading market.
Blockchain and public resource transaction information data management
According to the "China Blockchain Technology and Application Development White Paper 2016" issued under the guidance of the Ministry of Industry and Information Technology, in a broad sense, blockchain technology is the use of blocks Chained data structures are used to verify and store data, distributed node consensus algorithms are used to generate and update data, cryptography is used to ensure the security of data transmission and access, and smart contracts composed of automated script codes are used to program and operate data. A new distributed infrastructure and computing paradigm.
Essentially, blockchain technology is a technical solution that collectively maintains a reliable database in a decentralized, high-trust manner. In layman's terms, blockchain technology can be seen as an accounting method that supports the participation of all people.
Traditional data accounting involves multiple accounting entities and generates multiple data ledgers. Under this accounting method, due to the risks of lack of supervision, technical security risks, and physical security risks, the account data may be tampered with or lost, and it is difficult to trace relevant operational behaviors. Therefore, the objectivity, fairness, and security of the account data must be It’s hard to guarantee.
Blockchain technology provides a technical solution that supports multiple accounting entities to participate in accounting. When any accounting subject modifies the ledger, its modification behavior will form indelible traces (timestamps) in the ledger records, and the modification results will be synchronized to the ledgers of all accounting subjects, which prevents the account from being The risk of data tampering and loss can be traced back to relevant accounting behaviors to promote supervision.

In response to the information data management and credit issues raised above in the field of public resource transactions, blockchain technology can use its own "decentralization", "distributed data storage" and "traceability" ”, “anti-tampering characteristics”, “openness and transparency” and other advantageous features to effectively respond and solve.
Public resource transaction data is tamper-proof
The public resource transaction platform stores a large amount of public resource transaction data. With traditional centralized data storage management, once the data and backup are damaged or lost, it is difficult to recover, and due to There are loopholes in the supervision mechanism and the risk of data tampering.
Blockchain technology adopts "decentralization" and "distributed data storage". Data damage or loss in one or more data storage nodes will not affect the data security of other data storage nodes. At the same time, updates to data ledger records are shared and made public simultaneously, and operations traces are supported. Blockchain data cannot be tampered with or corrupted unless all nodes are compromised.
Establish a trustworthy public resource transaction data environment
Information asymmetry in the public resources trading market leads to adverse selection and moral hazard among market entities, affects the efficiency and quality of public resource trading, and affects the orderly operation and development of the public resources trading market.
Blockchain technology solves the problems of authenticity, security and openness of public resource transaction data, promotes the efficient sharing and application of credit information in the public resource transaction market, promotes the establishment of a trustworthy data environment for public resource transactions, and prevents and avoids Various credit risks provide trustworthy data decision-making support for market trading entities and regulatory entities

❽ What are the applications of blockchain technology

Developing Ethereum Cat based on Ethereum, this calculation Not counting apps, it’s a bit fun to play, and there’s NetEase Planet. For traceability, I have snapped up the Orange Chain made by China Enterprise Tongbao Blockchain, which is used for blockchain traceability records on Orange.

❾ How does blockchain technology “show its mettle” in the military?

In recent years, the application of blockchain technology has attracted widespread attention, whether in the financial field, enterprises, or Government departments are accelerating the research, development and application of blockchain technology. Some countries have also sensed the potential of blockchain technology in warfare and are striving to expand the breadth and depth of blockchain technology in military applications.

Blockchain technology is the "bulletproof vest" for military logistics. The decentralized nature of blockchain technology gives it a strong ability to recover information after an attack. Unless all computers in the system are destroyed, it is completely meaningless to modify the information of a node because the system can recover quickly. Complete form. The current logistics system relies too much on the reliability of the information service center. Once the information service center fails, it will affect the normal operation of the entire logistics system. Military applications have very high requirements on system security and wartime damage resistance. The use of blockchain technology can effectively solve the core issues such as information security, data storage and interactive processing faced by intelligent military logistics. The key point is to improve the logistics system. survivability, thereby ensuring the orderly and efficient operation of the system.

Essentially speaking, blockchain technology is a mutually trusted storage device that can be used for information transactions between multiple users. Its core is "distributed consensus" and "anonymity". Transactions can be verified at any time without affecting the privacy of the parties involved. Therefore, blockchain technology is bound to become a new generation of disruptive technology, and its military applications will become more extensive and in-depth.
