❶ What is btd

BTD is a digital asset in the distributed shared storage ecosystem based on blockchain technology, which is used to motivate users who participate in the construction of the BTD ecological chain. The BTD project was established in 2012. By 2017, the data technology research and development was completed, and then implemented in 2019. The team worked hard for 7 years to achieve the full implementation of public chains, wallets, exchanges and malls. At the end of October 2019, the BTD project began to launch a promotion model globally.

Blockchain involves many scientific and technical issues such as mathematics, cryptography, Internet and computer programming. From an application perspective, simply put, blockchain is a distributed shared ledger and database, which has the characteristics of decentralization, non-tampering, full traceability, traceability, collective maintenance, openness and transparency. These characteristics ensure the "honesty" and "transparency" of the blockchain and lay the foundation for creating trust in the blockchain. The rich application scenarios of blockchain are basically based on the ability of blockchain to solve the problem of information asymmetry and achieve collaborative trust and consistent action among multiple subjects.

Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms. Blockchain is an important concept of Bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of Bitcoin, it is a series of data blocks generated using cryptographic methods. Each data block contains information about a batch of Bitcoin network transactions, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block.

In the original English version of the Bitcoin white paper, the word blockchain does not actually appear, but the word chain of blocks is used. In the earliest Chinese translation of the Bitcoin white paper, chain of blocks was translated into blockchain. This is the earliest time when the Chinese word "blockchain" appeared.

The Cyberspace Administration of China issued the "Blockchain Information Service Management Regulations" on January 10, 2019, which will come into effect on February 15, 2019.

As an important breakthrough for independent innovation of core technologies, the security risk of blockchain is regarded as a major shortcoming that currently restricts the healthy development of the industry. Frequent security incidents have sounded the alarm for the industry. To embrace blockchain, we need to accelerate the exploration and establishment of a security system that adapts to the blockchain technology mechanism.

❷ Is blockchain technology really going to be a post-Internet era? What is its manifestation?

Yes. In essence, it is a shared database, and the data or information stored in it is "unforgeable", "leaving traces throughout the process", "traceable" and "open and transparent"Features such as “collective maintenance”. Based on these characteristics, blockchain technology has laid a solid foundation of "trust" and created a reliable "cooperation" mechanism, which has broad application prospects.

The foundation of blockchain technology is open source. In addition to the private information of the parties to the transaction being encrypted, the blockchain data is open to everyone. Anyone can query the blockchain data through the public interface. and develop related applications, so the entire system information is highly transparent. As long as you cannot control 51% of all data nodes, you cannot manipulate and modify network data at will. This makes the blockchain itself relatively safe and avoids subjective and artificial data changes. Blockchain technology does not rely on additional third-party management agencies or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, each node realizes self-verification, transmission and management of information through distributed accounting and storage.

❸ Can blockchain technology solve the problem of information asymmetry? If so, will it involve a large number of intermediaries and trade associations?

One of the theoretical foundations of blockchain is game theory. Question The information asymmetry problem mentioned by the Lord often occurs in the actual scenario between the upstream and downstream of the supply chain. The upstream hopes to sell more expensively, while the downstream hopes to buy cheaper. This will lead to a game between upstream and downstream.

The other is the competitive game between peers, such as two suppliers, and a very important means of competition in this game is through the collection of first-hand information. Through information asymmetry, we can grasp the market trend and obtain higher economic profits.

Blockchain technology can achieve transparent sharing of information between parties and guarantee trust. Therefore, the problem of information asymmetry can be completely solved through blockchain technology.

As for whether intermediaries will be completely eliminated? In my opinion, this is not achievable in the short term. However, judging from the development trend of blockchain technology and future prospects, the share of dealers as intermediaries will definitely be gradually reduced and will be abandoned by the times.

The above are some of my personal views and opinions.

❹ Can you analyze the information asymmetry problem in the second-hand car market and give some countermeasures and suggestions?

First of all, give some suggestions for the information asymmetry problem in the second-hand car market : Establish a trust distribution system; strengthen market supervision; and improve information construction.

(2) Strengthen market supervision

The government strengthens supervision of the second-hand car market, regulates sellers’ trading behavior, and improves information Transparency and continuous improvement of the construction of automobile sales
information platform. Strengthen the supervision and management of second-hand car quality appraisal institutions,
establish an authoritative second-hand car evaluation institution, establish credibility, and continuously regulate its development.

(3) Improve information construction

Establish a soundAll second-hand car files are informatized and an electronic business network trading platform is created to combine physical stores and e-commerce platforms to realize second-hand car information sharing and improve information transparency and consumer trust.

❺ Is blockchain technology a devil or an angel?

Both good and bad are more good and less bad

Blockchain Technology , in the final analysis, it is the sharing of information and data.

Whoever masters this technology will have the opportunity to develop the economy and trade, and have the initiative to do business.

Its characteristics are: unforgeable, leaving traces throughout the process, traceable, open and transparent and collectively maintained.

Therefore, both devils and angels will use blockchain to serve themselves. It’s just that whoever has advanced technology and is powerful will be at the top.

Aren’t each of us the incarnation of devils and angels? ? What's more, it's a technology? The key depends on how you use it,

Technology is neutral, neither an angel nor a devil. The key is who controls it. If angels dominate, the world will become a better place. If the devil dominates, it will be hell on earth.

In essence, blockchain is a shared database. The data or information stored in it has the characteristics of "unforgeable", "full traces", "traceable", "open and transparent" and "collectively maintained". ” and other characteristics. Based on these characteristics, a solid foundation of "trust" has been laid, a reliable "cooperation" mechanism has been created, and it has broad application prospects, especially in the financial field, which will bring unprecedented experience to people.

Blockchain technology is an advancement in network development and is widely used in the military. It is not available for civilian use yet. It is also not suitable for civilian use in our country. Therefore, if it can be used, it is an angel

Blockchain technology is neither an angel nor a devil. At present, this confidentiality and sharing technology is relatively advanced, but it is a bit untimely. will be quickly eliminated in the future!

First of all, let me explain the general meaning of blockchain technology: blockchain is a distributed shared ledger and database, which is decentralized, cannot be tampered with, leaves traces throughout the process, can be traced, and is collectively maintained. , openness and transparency and other characteristics. These characteristics ensure the "honesty" and "transparency" of the blockchain and lay the foundation for creating trust in the blockchain. The rich application scenarios of blockchain are basically based on the ability of blockchain to solve the problem of information asymmetry and achieve collaborative trust and consistent action among multiple subjects.

To put it more straightforwardly, blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. (A rougher understanding is that the main business of this technology is encrypted files and the side business is virtual currency)

One of the biggest hidden dangers - the birth of commercial quantum computers

1. Since IBM announced the launch of the first commercial quantum computer in early 2019, the possibility of micro personal quantum computers has become infinitely larger. . If anyone still doesn’t understand why quantum computers are mentioned here, then I can tell you responsibly that the power of quantum computers is that currently the most difficult passwords are as fragile as white paper in front of quantum computers!

2. The uncertainty faced by the blockchain. Currently, mainstream scientists have proposed two solutions to the upcoming quantum computers. The first one: Tailor-made for quantum computers and rewriting blockchain technology. (Currently, I have only written an outline, but no specific details.) The second type: write rules and regulations into the hardware of each quantum computer that is about to leave the factory, prohibiting the use of various modes to crack blockchain technology. (I personally don’t believe in the second method. Rules and regulations are easy to write and easy to implement on computers. However, some countries basically have no credibility at all. It is inevitable that they will default on their obligations and even open a backdoor program on it...)

3. The relationship between blockchain technology and digital currency. Take the digital currencies issued by central banks of various countries as an example. They draw on part of the blockchain technology. Although the mechanism is independent and obviously has a higher security level than the blockchain, it also faces risks because this technology is also based on the current computer working environment. from.

Summary: The best technology is not perfect. In the future, digital currency will definitely replace the original paper currency, but future risks may arise due to loopholes. And it becomes even more dangerous...

The progress of science and technology1 is indeed accompanied by the rise of emerging industries and the decline of traditional industries. Be objective in understanding.

I don’t understand and am confused

Is the blockchain issue a technical job? I don't think so. I think it should be broken down from the perspective of the system of the universe, of which the solar system is a part. As for how to block other galaxies, astronomers are still in the process of brewing it. It is a matter of the future. What we have to do now is We can only start from the territory of the earth. The result is either a continent or a country. Of course, there are also the problems of the religious consciousness of numerous ethnic groups and nations, as well as the connection problems of blocks in people and things.

I haven’t quite figured out the content and meaning of blockchain yet. At present, it should be good

❻ How extensive is the scope of blockchain?

Blockchain is as widespread as the Internet. The future trend is increasingly towards blockchain. To be honest, many binance chains, Binance Smart chains, etc. are practical applications of blockchain.

❼ What is blockchain in simple terms

Blockchain is a technology in the field of information technologylanguage. Essentially, it is a shared database. The data or information stored in it has the characteristics of "unforgeability", "whole process traceability", "traceability", "openness and transparency" and "collective maintenance". Based on these characteristics, blockchain technology has laid a solid foundation of "trust" and created a reliable "cooperation" mechanism, which has broad application prospects.
On January 10, 2019, the Cyberspace Administration of China issued the "Blockchain Information Service Management Regulations". Blockchain has entered the public eye and become the focus of society. From a technological perspective, blockchain involves many technological issues such as mathematics, cryptography, the Internet, and computer programming.
Extended information:
