⑴ What are the advantages of using blockchain technology in anti-counterfeiting traceability of goods

In the early days of the "blockchain era", people's understanding of blockchain was limited to Digital currency and currency speculation operations. With the development of technology, people realize that applying blockchain technology to industries and promoting the economic development of the industry is its true value. Blockchain traceability and anti-counterfeiting is considered to be one of the most promising areas for blockchain implementation, and it is also one of the first areas where giants compete for the implementation of blockchain application technology. It can be said that whoever can launch the first implementation project will be one step ahead in the industry.
With the help of blockchain technology, information on the circulation process of commodity raw materials, production process, commodity circulation process, and marketing process will be integrated and written into the blockchain to achieve one-item, one-code, full-process authenticity traceability. Blockchain technology is used to digitize the information of participants in different commodity circulation and store it in the blockchain. These include origins, manufacturers, distributors, retailers, brands and consumers. Make each participant's information viewable in the blockchain.
With the help of blockchain technology, the information of all aspects of the goods from production to warehousing is integrated and written into the blockchain. Each piece of information has an independent and special blockchain ID, accompanied by the digital signature and digital signature of the goods. Timestamps provide users with good underlying data support and product quality control.
At the consumer level, through terminal traceability QR codes and open and transparent blockchain technology support, users can easily check the authenticity of products, cultivate users' awareness of authenticity, and enhance brand value.
Due to the complex and difficult-to-verify transaction content and the temptation of high profits, counterfeiting and selling of counterfeit products are frequently prohibited in the market. This not only affects the shopping experience of consumers, but also damages the brand image of merchants. For merchants and consumers, it is urgent to establish a credible anti-counterfeiting traceability system.
All commodity transactions in the entire market must be supported by a trustworthy anti-counterfeiting traceability mechanism. In this way, we can better ensure the quality of the company's own products and improve consumers' shopping experience.

⑵ Problems with Blockchain

Blockchain has certain uses, but it is by no means omnipotent.

There are two main problems with blockchain.

1 The blockchain cannot verify the authenticity of information outside the system. If the information uploaded to the blockchain itself is false, the anti-counterfeiting and anti-tampering of the blockchain will be worthless. To ensure that the uploaded information is authentic, there still needs to be an authoritative agency to check it. Since we all trust the information uploaded by this authoritative organization, why should we be afraid of it tampering with the information? What difference does it make if we use blockchain or not?

2 In the blockchain world, code is the law, and the system can run automatically. However, once it interacts with the real world, the real world may not necessarily agree with the law of the code. For example, if a contract is signed on the blockchain, it will be automatically executed when it expires and the assets will be transferred. However, if there is a bad guy in reality, the contract will not be executed according to the contract on the blockchain.The contract implements the asset transfer in reality. This contract is a piece of paper and requires the action of the courts and other institutions in reality.

The first practical application of blockchain, Bitcoin, has such great influence because it can avoid the above two problems.

Bitcoin is completely self-contained. All information is generated within the Bitcoin system and is closed and verifiable. Bitcoin is not linked to any real assets, so it can be easily passed through The program runs automatically.

Because Bitcoin is completely virtual and operates entirely on procedures and rules, it has no borders, is not subject to regulatory control, does not require exchange, circulates freely, cannot be frozen or confiscated, is available to everyone, and will not be over-issued or devalued. , which is its advantage over legal currency.

However, because Bitcoin completely relies on fixed rules and procedures to operate automatically, the supply of Bitcoin is inelastic. If the private key is stolen, the property will be lost and cannot be recovered. This is why it Shortcomings.

Similarly, when using blockchain technology in reality, if we really pursue that code is the law and the private key proves everything, if the private key is stolen, the assets will inevitably be lost and cannot be recovered. For example, if shares are mapped to the blockchain, is it possible that if a major shareholder loses his private key, all his shares will become unusable? This is also an unavoidable problem with blockchain.

In summary, the real killer application of blockchain is actually cryptocurrency. Developing a currency-less blockchain is not that disruptive, and we must be wary of some scammers using the banner of blockchain to defraud money and subsidies.

⑶ Is the blockchain reliable?

With the development of the times, there are now Many science and technologies are used in people's lives, and blockchain is a very widely used Internet technology. The purpose of blockchain is to verify the validity of information, so it has anti-counterfeiting functions. Blockchain is a combination of many data blocks in a chain structure in time order to maintain the reliability of the database. The application fields of blockchain are also relatively wide, and are often used in finance, the Internet, insurance, and some public welfare fields. Blockchain is divided into public and private. Its biggest features are high transparency, decentralization and collective maintenance. Because it is used too widely, many people have doubts about blockchain in daily life. I don’t know. Is it reliable?

Generally speaking, blockchain technology is not a scam. It is reliable, but it also has certain disadvantages. Blockchain technology can have great benefits if applied in legal fields, but once it goes astray and is introduced into illegal fields, it will have very serious consequences.

⑷ Why do many people say that blockchain is a lie?

Blockchain is not a lie, it is a lie.People who use blockchain as a guise to deceive people. In fact, blockchain scams take advantage of people's lack of understanding of the technology, and then scammers rely on a variety of fancy methods to set up scams. Many people only look at the surface when making investments, and are eventually lured into the trap by high profits.

In today's society, more and more people are willing to take the risk to invest in order to obtain huge returns, but not everyone can make a profit. After all, there are benefits. There are many people squatting and watching, and they will set traps for people to take the bait.

(4) Extended reading on the authenticity of current blockchain:

Notes

Blockchain is a Technology, simply put: This technology is based on new ways of data management such as cryptography. Blockchain technology has broad application prospects because of its advantages such as decentralization, non-tampering, full traceability, and traceability. Issuing coins is an act derived from blockchain technology. At present, the vast majority of blockchain applications that focus on issuing and speculating coins are suspected of illegal fund-raising.

Blockchain technology is still in its early stages of development, and its application is also difficult to implement. If you rely solely on a white paper to claim that there is an application, it is an act of deception in itself.

⑸ How to distinguish real and fake blockchains

There is a special group of people who like all kinds of financial investment projects and are looking for projects all year round, especially in the blockchain industry. In the field of blockchain, the background of creating huge wealth miracles has also inspired many capital projects under the cloak of blockchain, and these investors looking for projects have naturally become leeks for various complicated projects, turning the projects into If you do it as a career, you will end up hurting others and yourself! The reasons are that one is not enough knowledge, and the other is the wrong mentality. You can't always think about getting rich overnight. A truly good career is built down-to-earth through the accumulation of value over time. If you don't have such a correct mentality, you will be like the above. The people mentioned are always looking for projects to do, but in the end they hurt others and themselves; apart from spending money to buy lessons, the best way to improve cognition is of course learning, and the most efficient way to learn is of course to learn systematic knowledge. The Jiguang Community provides such a professional learning platform to popularize structured and systematic blockchain knowledge for free. Here we will first popularize the anti-fraud knowledge.

First, let’s be clear about one fact. There is no truly mature currency circle in China, and most of them are capital projects disguised as blockchains. Therefore, when making a choice, you must understand and be cautious. The key is to protect your principal!

Second, how to distinguish true from false:

Judging from the entry threshold, there is no entry threshold for real blockchain projects. Anyone can participate, regardless of asset size. And it is free to enter and exit, without your principal, without custody of funds, and the assets will always belong to the users.

From the perspective of income distribution, the real income of the blockchain is earned by users through their contributions rather than the so-called pulling. A human head can truly produce blood and produce value, rather than a zero-sum game

Third, howDistinguish whether it is truly decentralized:

From the product side, all codes must be open source and put on the chain; they must be audited by authorities; all data must be on the chain, and user data must not be stored or infringed upon.

< p>From the governance side, it is initiated and run by the DAO organization; it has its own governance group; it has its own proposal mechanism

⑹ Is the blockchain a lie?

" "Blockchain" is an important concept in the new era. It is essentially a centralized database and the underlying technology such as digital currency. According to our popular explanation, the "blockchain" can be regarded as a ledger, and each bill is a block. However, this ledger is centralized, and it can be said that no company or team has jurisdiction over it. "Blockchain" technology is a unique informatization that is centralized and cannot cross-change information. Now in daily life, this technology has been applied to a series of applications such as electronic invoices and payment codes.
In today's life, many people use this guise to commit fraud. Direct sales disks, capital disks, technology disks and other names are used to lure people to make money and then run away. As a result, many people have lost their funds and have nowhere to defend their rights. In the end, I can only say that "blockchain" is a lie. There is no right or wrong in technology, it’s the people who are wrong.
With the progress of the times and the progress of society, the initial application of any technology will be subject to various positive and negative doubts. However, with the relative application and maturity of technology, coupled with the improvement of technology, various aspects around people have formed. This application will continue to improve, and I believe that these doubts will slowly dissipate in the near future.
The following is a summary of some blockchain scams that are often around you!
Trap 1: Blockchain is about issuing coins to make money
Trap 2: Conducting virtual currency transactions, promising low investment and high returns
Trap 3: Decentralization can solve all problems
Trap 4: With the extension of the blockchain, you can make money with a mining machine
Trap 5: Transactions on WeChat and Alipay to buy and sell virtual currencies
In short, the methods of scammers are also advancing with the times. Through our "eyes of wisdom", we can improve and enhance our adaptability, discover and alert ourselves, and prevent being deceived. Investors must be wary of various deceptive methods that offer low investment and high returns.

⑺ Is the blockchain technology a lie? Is it actually related to our lives?

How can something useful be useless

In recent years , more and more people regard blockchain technology as one of the most promising new technologies in the future. Right now, there is a lot of talk about how cryptocurrencies and blockchain will change the world economy. Although the future of cryptocurrencies is unpredictable, the unshakable status of blockchain may continue to lead the development of the industry in the future. In fact, blockchain has changed not only the world economy, but even the daily lives of ordinary people have been greatly changed by its impact. The emergence of blockchain technology itself is an innovative process. Anyone who understands blockchain technology should know that blockchain is a platform that can collaborate on a large scale.database. It allows many different subjects to collaborate to complete a task without trusting each other. This is the essence of blockchain.

Since this year, there have been numerous cases about blockchain technology supporting the resumption of work and production of small and medium-sized enterprises.

⑻ Is blockchain a scam?

The word blockchain So it was mentioned first because after Bitcoin entered people's attention, with the fermentation of Bitcoin craze and the proliferation of topics, blockchain has become a familiar topic to the general public. It once became a greeting among entrepreneurs (what are you doing? Is it blockchain? Is your entrepreneurial project related to blockchain? Etc.) The application of blockchain in the market is very crowded now, and ordinary people’s concept is almost stuck in the stage of speculation. What is blockchain? Is blockchain a lie?

From a global perspective, it is not only our listed companies, shareholders, everyone in the currency circle and investors who are fascinated. In 2016, Citibank, BBVA, JPMorgan Chase, Morgan Stanley, Swiss Leading financial institutions such as Bank of China have jointly established the R3CEV Alliance (Goldman Sachs Group has now separated from the R3CEV Blockchain Alliance). Therefore, from this perspective, blockchain technology has been applied to a certain extent around the world. At this level, blockchain It is a new invention, and I am not lying. Many readers are curious why many people now hear that blockchain (digital currency) is like a scam. Buffett said: Stay away from Bitcoin, it is just an illusion. In my opinion, it has great intrinsic value The idea is a joke.

The author thinks that there are no correct mistakes in technical books, but the mistakes that application macro practitioners think are correct. Many people envy the currency circle (application of blockchain) to make a fortune overnight, but forget that Returning to poverty overnight (its multiple currency operation methods are the same as those of silver spot stamps, cards, etc. at that time). This should be people’s most intuitive concept of blockchain.

What is blockchain? Is blockchain a lie?

The definition of blockchain in the Internet Encyclopedia is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. The consensus mechanism is to realize the connection between different nodes in the blockchain system. A mathematical algorithm that establishes trust between people and obtains rights and interests.

⑼ How to identify the authenticity of a blockchain white paper

In the currency circle, you can make a fortune by relying on a white paper and air coins. Stories of getting rich are common. The digital currency industry based on blockchain technology is very hot. In this industry, the most indispensable thing is leeks and people who want to cut them. The proliferation of air coins has given rise to a new industry - "blockchain white paper ghostwriting".

Currently, there are a large number of"Blockchain white paper writing" business. In addition to Taobao, there are more than 100 shops engaged in blockchain white paper writing business on Zhubajie.com. Some stores claim to be able to conduct overseas advertising and even create project information on Wikipedia. The addresses of such stores are basically first-tier cities such as Beijing, Shanghai, Guangzhou and Shenzhen, and most stores support on-site negotiation of transactions. People in the blockchain industry said that the routines of many ghostwritten white papers are basically the same and are not particularly difficult. “There are standard templates for everything, and a lot of it is ready-made.”

These white paper ghostwriters are targeting a weak point in today’s blockchain market: most entrepreneurs don’t understand the issues surrounding blockchain What content should be included in the formal white paper of chain technology has become the reason to support the entire black production line.

Taobao’s actions obviously only cleaned up a very small part, and these “magic hands” cleverly avoided surveillance. When Gray Production Circle asked a Taobao merchant who had communicated with him before why he could not search for his store, the other party said that he could enter by clicking on the link he sent.

The irony is that these white paper ghostwriters who are waging a "guerrilla war" with Taobao are pure scams. The Gray Industry Circle learned from a ghostwriter that most of the writers behind these "Taobao white papers" are ordinary copywriters. Not only do they not understand blockchain technology, they can't even write code, but they claim that they "There's logic too."

An insider who wrote a blockchain white paper even directly told the gray industry circle: "If you have an idea, give me an idea. If you don't have an idea, give me an outline. You don't have to give me an outline." I can go in one direction, and we will make a logical white paper for you."

So, how should we stay vigilant about "white papers"? The project is unrealistic, the content is obscure and difficult to scrutinize, the project is copied to gain popularity, and the strength of the team is infinitely exaggerated.

For ordinary people and capital, blockchain represents the ability to make quick money. The gathering of summits, celebrity platforms, and even the attendance of aunts have pushed the blockchain into wave after wave, but we must believe that under the supervision of multiple parties, valuable blockchain project white papers can be truly implemented. application and serve society.

The Xueshuo Innovation Blockchain Technology Workstation under Lianqiao Education Online is the only "blockchain technology" approved by the "Smart Learning Workshop 2020- Xueshuo Innovation Workstation" carried out by the School Planning and Construction Development Center of the Ministry of Education of China. Professional” pilot workstation. The professional base is based on providing students with diversified growth paths, promoting the reform of the training model integrating professional degree research, production, and research, and building an applied and compound talent training system.

⑽ Several of my friends are playing with blockchain. Is it reliable?

Blockchain is also a relatively new thing, and many people are interested in it. For those who pay attention to blockchain, blockchain can be loved by many people, and it can also gain investment from many people. Many people particularly want to invest in blockchain, and they also hope to gain more by investing in blockchain. More rewards.

There are many people who want to invest in the blockchainPeople who don't know blockchain may not necessarily understand blockchain, and they don't know how to operate blockchain. If you invest in blockchain because everyone around you invests in blockchain, 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.
