① Is blockchain technology expected to lead mankind into the era of machine trust?

Recently, the concept of blockchain has made a comeback. Since February, the U.S. House of Representatives has held two blockchain hearings in succession, elevating blockchain to a "revolutionary technology" and exploring its future applications and impact on finance, business and government. At the same time, Russian President Vladimir Putin also stated that Russia will focus on developing blockchain technology to strengthen Russia’s voice in international competition in the field of cutting-edge technology. In China, more and more industries are beginning to pay attention to the field of blockchain technology, and this concept has also become one of the hot topics discussed by representatives during this year's "Two Sessions".

In today's turbulent era of technological advancement, there are still many places for us to explore in depth as a new technology called blockchain. Especially in high-tech fields where others have formulated the "rules", we should take a long-term view, continue to innovate, digest and absorb the essence of blockchain technology, and strive to form core competitiveness with independent intellectual property rights. At the same time, in the face of various temptations, we need to be cautious at all times, see risks, avoid losses, and never let the light of economic interests obscure our understanding of the essence and deep value of blockchain.

② BT110: What benefits does blockchain technology bring to the information security industry?

The significance of blockchain to the information security industry is reflected in the following three points:
1. Users Identity authentication protection
Asymmetric public and private key encryption technology uses two sets of key systems, which is more secure than symmetric encryption. Most public key encryption is implemented on the PKI platform, which can easily be used by hackers to impersonate identities. The WhatsApp vulnerability was exploited by hackers Send fake keys to perform man-in-the-middle attacks.
Blockchain can build a new identity management system. The identity identification algorithm used by business secret mail makes it difficult to conceal tampering, thus effectively preventing identity forgery.
2. Data Integrity Protection
Once the traditional encryption algorithm is tampered with by a man-in-the-middle, the participants in the network cannot detect it in time. Similar things often happen in the transaction emails of some companies: sending emails There is no problem with the person's email address, but the receiving account has been tampered with, and this type of email fraud is usually not discovered until the damage has been done.
The U.S. Department of Defense’s DARPA Advanced Research Projects Agency is considering using blockchain to protect sensitive military data. Blockchain uses a hash algorithm to store data. Data blocks are connected to each other. Any data tampering will cause changes in the block sequence value. No matter how large the network is, the source of the tampering can be easily found.
3. Effectively prevent DDoS attacks
The intensified DDoS attacks have made enterprises daunted. An advanced DDoS attack can even easily bring down a large enterprise. This is also the first choice for hackers to try to carry out large-scale damage.
The distributed storage architecture of blockchain will make hackers at a loss. Some companies have begun to develop a distributed Internet domain name system based on blockchain to eliminate the shortcomings of current DNS registration.to make the network system cleaner and more transparent.

③ 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. Soon 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 is the birth of commercial quantum computers

1 , since 20Since IBM announced the launch of the first commercial quantum computer in early 2019, the possibilities of micro personal quantum computers have 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

⑤ What are the main application fields of blockchain technology?

Answer: The main application fields of blockchain technology are financial field, Internet of Things and logistics field, public service field, digital copyright field, insurance field and public welfare field.

1. Financial field

Blockchain has potential huge application value in financial fields such as international exchange, letters of credit, equity registration and stock exchanges.

2. Internet of Things and Logistics Fields

Blockchain can also be naturally combined in the Internet of Things and logistics fields. Through blockchain, logistics costs can be reduced, the production and delivery process of items can be traced, and the efficiency of supply chain management can be improved.

3. Public service fields

Blockchain is closely related to people’s production and life in public management, energy, transportation and other fields, but the centralized nature of these fields also brings Some problems can be solved using blockchain.

4. Digital copyright field

Through blockchain technology, works can be authenticated, prove the existence of text, video, audio and other works, and ensure the authenticity and uniqueness of ownership. sex.

5. Insurance field

In terms of insurance claims, insurance institutions are responsible for fund collection, investment, and claims settlement, and often have high management and operating costs.

6. Public welfare fields

The data stored on the blockchain is highly reliable and cannot be tampered with, so it is naturally suitable for use in social welfare scenarios. Relevant information in the public welfare process, such as donation projects, fundraising details, fund flows, recipient feedback, etc., can be stored on the blockchain and transparently and publicly disclosed conditionally to facilitate social supervision.

⑥ BMEX: The beginning of the long-term prosperity of the blockchain industry has arrived. What is blockchain technology?

1. The concept of blockchain technology

Blockchain technology is a new technology that has gradually emerged with the rise of encrypted digital currency. It adopts a distributed computing model, uses blockchain to store data, and uses cryptographic principles to ensure the security of transmission and access. Data storage is jointly maintained and supervised by Internet users. It has significant characteristics such as decentralization, transparency and openness, and data cannot be modified [2]. It uses distributed storage and computing power to make the rights and obligations of the entire network nodes the same. In the system The nature of data is jointly maintained by nodes across the entire network, so the blockchain no longer relies on central processing nodes to achieve distributed storage, recording and updating of data. Therefore, its application is not limited to currency as an asset type, and is currently used in various industries. The application research is relatively extensive.

⑦ 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 militaryThe "bulletproof vest" of 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.

⑧ What is the military application value of blockchain technology?

There are many possible potential applications of blockchain technology in the military field:
Intelligence work performance incentives. Blockchain has the anonymity feature when recording transactions and can be used for covert targeted payments of intelligence work incentives. As we all know, intelligence providers or "informants" need to keep their identities and whereabouts secret, and traditional payment methods such as transfers and cash can easily be tracked or even locked. However, by using Bitcoin as a payment intermediary, the payment channel can be cleverly "broken", making the flow of intelligence funds difficult to trace, thereby effectively protecting security. The Bitcoin trading platform plays the role of a "black box" in the entire payment process, in which the three key links of "purchase-transaction-exchange" can be completed anonymously, hiding the key information of both parties to the transaction.
Full life management of weapons and equipment. Equipment needs to register and manage important information throughout its life cycle from project establishment and verification, production verification, delivery to service, to decommissioning and scrapping. The current recording method is usually paper or electronic media. This traditional method has difficulties in ensuring safety and Defects such as difficulty in transfer and handover and lack of effective supervision. If blockchain technology is introduced, higher-level authorities, equipment management departments, equipment users, and even equipment manufacturers can participate in the update and maintenance of equipment combat status, forming a distributed and supervised file registration network. If all parties keep a complete copy of the file, the above problems can be effectively solved and the security, convenience and credibility of the file can be improved.
Military intelligent logistics. For modern military logistics to be truly intelligent, it cannot be separated from the intelligence of participants such as logistics departments, warehouses, materials and material demand parties, which constitutes the small Internet of Things. Blockchain technology can effectively solve the problems of network communication, data storage and system maintenance. Dynamics of people and things in the system,Autonomous networking forms a decentralized peer-to-peer network without the need for a central server. The distributed structure improves the survivability of the system; nodes connected to the network can communicate directly or through relays to achieve free exchange of information. ; Important data information in the logistics chain, such as user needs, warehousing goods, loading and transportation, distribution transfer, etc., are stored in each block; the maintenance of the blockchain must be subject to the supervision of the entire network nodes, and illegal operations of individual nodes will be punished. Most nodes refuse and resist, ensuring the orderly and efficient operation of the system. (Reprinted from Science and Technology Daily)
Of course, blockchain is mostly used in the financial field, such as Biying China’s digital currency crowdfunding; China Post Bank’s fund custody, etc.

⑨ What are the applications in the blockchain field?

Blockchain application fields:
1. Financial field. Blockchain has potentially huge application value in financial fields such as international exchange, letters of credit, equity registration and stock exchanges. The application of blockchain technology in the financial industry can eliminate the need for third-party intermediaries and achieve direct point-to-point connection, thereby greatly reducing costs and quickly completing transaction payments.

2. Internet of Things and logistics fields. Blockchain can also be naturally combined in the Internet of Things and logistics fields. Through blockchain, logistics costs can be reduced, the production and delivery process of items can be traced, and the efficiency of supply chain management can be improved. This field is considered to be a promising application direction of blockchain.

3. Public service field. Blockchain is closely related to people's production and life in the fields of public management, energy, transportation, etc. However, the centralized nature of these fields also brings some problems, which can be transformed with blockchain. The decentralized, fully distributed DNS service provided by the blockchain can realize domain name query and resolution through point-to-point data transmission services between various nodes in the network, and can be used to ensure that the operating system and firmware of an important infrastructure are not Tampered, you can monitor the status and integrity of the software, detect bad tampering, and ensure that the data transmitted by systems using IoT technology has not been tampered with.

4. Digital copyright field. Through blockchain technology, works can be authenticated, proving the existence of text, video, audio and other works, and ensuring the authenticity and uniqueness of ownership. After the rights of the work are confirmed on the blockchain, subsequent transactions will be recorded in real time, realizing full life cycle management of digital copyright, and can also be used as a technical guarantee in judicial evidence collection. For example, Mine Labs, a startup company in New York, USA, has developed a blockchain-based metadata protocol. This system called Mediachain uses the IPFS file system to realize copyright protection of digital works, mainly for copyright protection applications of digital pictures.

5. Insurance field. In terms of insurance claims, insurance institutions are responsible for fund collection, investment, and claims settlement, and often have high management and operating costs. Through the application of smart contracts, there is no need for policyholders to apply, and does not require the approval of the insurance company, as long as the claim settlement conditions are triggered, the policy will realize automatic claim settlement. A typical application case is LenderBot, which was launched in 2016 by the blockchain company Stratumn, Deloitte and the payment service provider Lemonway. It allows people to register customized micro-insurance products through the chat function of Facebook Messenger and exchange between individuals. high-value items are insured, and blockchain replaces the role of a third party in the loan contract.

6. Public welfare field. The data stored on the blockchain is highly reliable and cannot be tampered with, so it is naturally suitable for use in social welfare scenarios. Relevant information in the public welfare process, such as donation projects, fundraising details, fund flows, recipient feedback, etc., can be stored on the blockchain and transparently and publicly disclosed conditionally to facilitate social supervision.
