从以上内容可以看出，区块链技术和互联网技术之间的关系越来越紧密，可以从三个关键词：去中心化、可信任性和安全性来概括这种关系。区块链技术可以让用户在不需要中央机构、信任任何第三方机构和任何第三方机构的情况下实现安全的交易。

『一』Why do you say that the value of blockchain is 10-100 times that of the Internet

Why do you say that the value of blockchain is 10-100 times that of the Internet

The entire history of mankind and the history of the Internet can be described in eight words, that is: "If we divide for a long time, we will unite and we will unite for a long time."

In the United States in the 1980s, there were A giant called AT&T (American Telephone and Telegraph Company) was able to completely monopolize the resources of that network, but then a network protocol that could decentralize appeared, that is, TCP/IP (protocol). Because of this TCP/IP ( After the emergence of the Agreement), the Internet was born immediately. Just overnight, the monopoly of network resources of the entire AT&T team disappeared immediately. This is an era of long-term cooperation and separation

However, in the era of long-term separation, it is because all this network information is scattered on the entire Internet, and everyone has to dig it. This information is very difficult to retrieve early, and then it immediately appears again. New centralized platforms are like Google. and Facebook, some of our core data originally belonged to us, but now they are immediately flowing to these central platforms. In the era of blockchain, it is an era of long-term integration and inevitable division. All this data has been transferred to our own. In hand,

Why did the market value of Google and Facebook at that time be 10-100 times that of AT&T? That was the era of blockchain, and the technology created was 10-100 times that of the previous Internet!

『二』 What are the relationship between social networks and blockchain and what are the potential applications

The Internet has connected the world, but for children whose values ​​have not been fully formed, , some negative energy information on the Internet can easily affect their physical and mental development, so Papa Mama Youliang appears to be very cautious about children's use of social media.

However, don’t underestimate the curiosity of babies. Sometimes Mommy’s over-protection can have the opposite effect. Xiao E thinks that we don’t need to completely deny the value of social networks because of a small number of negative cases. Using them correctly can bring more benefits to children than disadvantages:

Make more friends

The Internet breaks geographical restrictions, and babies can make friends with different people on the Internet. Racial friends, while broadening children's horizons, can also convey a positive voice to those in need.

Recognized by more people

Compared with real things and society, speech on the Internet is freer. Children can express their opinions and opinions freely without having to win over the mainstream. cultural identity.

On the other hand, children’s questionsYou can also get high-quality assistance and answers on social networks as soon as possible.

More willing to express themselves

Social media allows children to share their works freely without so many restrictions and restrictions, especially for introverted children, the Internet is a good A way to express yourself.

Note: If a child uses social media, a responsible daddy will definitely pay close attention to the changes in the child. So, what changes are worthy of vigilance?

Suddenly stops sending messages

If your baby is usually very active on the Internet and suddenly stops updating one day, this is a warning sign that he may have encountered some trouble. Son, he may even have blocked his eyes.

Refuse to hand over your mobile phone

Although it is very necessary to give children appropriate privacy, when children are very young, the content they read still needs to be controlled by adults. If the baby shows panic or refuses when Mommy wants to check her phone, Mommy should be very careful.

Change usernames frequently

If the baby frequently changes usernames, in addition to coveting freshness, they may also be hiding something or avoiding certain people, Daddy. Mom should also pay attention.

『三』What do blockchain technology and the Internet have in common?

Chongqing Jinwowo Analysis and Research: Blockchain operates based on the Internet, but its functions are wider than the Internet . The similarities between the two technologies mainly lie in
:
(1) In terms of data transmission methods, neither the Internet nor the blockchain requires a centralized intermediary;
(2) Both technologies Users are required to access the Internet;
(3) Both technologies can satisfy the simultaneous use of multiple users within an organization.

『四』Why is it said that the blockchain is ten times as powerful as the Internet

The data transmission speed and efficiency of the blockchain are faster than the Internet model, and the effect is geometrically increased . Therefore, it is said that the blockchain is ten times more powerful than the Internet.

『Wu』 Is blockchain technology really a post-Internet era? What is its manifestation?

Yes, blockchain must be a necessary technology in the post-Internet era.

Specifically reflected in its non-tamperability and the ability to achieve decentralization:

1. On the Internet, value and rights can be transferred.

2. A decentralized system can be built so that multiple parties can trust each other.

The first point is that value and rights can be conveyed on the Internet.

We all know that it is easiest to copy and paste on the Internet, and we can easily transfer information. However, if value is transferred on the Internet, the information may be stolen and tampered with. With blockchain technology, the information we put on the Internet can not be tampered with, and we are not afraid of being stolen. Therefore, you can interact with each otherThe transfer of value and rights on the Internet is proven.

There are too many examples of value transfer. For example, Bitcoin is a digital asset that can be transferred at will through the Internet, and does not require a centralized organization to manage it.

But how to understand the transfer of proof of equity? For example, when we go to handle government affairs, we often encounter that I go through a procedure at a window of a department, and then take the paper procedure and go to the window of the next department. Although we have experienced the Internet for so many years, we still have to go through so many processes and handle various paper documents. Why is this?

This is because technology is now very developed, and it is actually very easy to tamper with some electronic documents. Without the combination of blockchain, it is more difficult to trust the electronic information you submit. Therefore, in order for the window department to know that you are yourself and that you are willing to apply for the application, you often need to bring your ID card and then fill in the information in person on site to ensure that you are applying for it out of your own will. This way nothing goes wrong.

Combining blockchain and face recognition, it can be done. The procedures I completed in one department are put on the blockchain, and the other department only needs to complete the procedures on the blockchain. If you check it online, you will know that I have gone through the relevant preparatory procedures myself, and then I can proceed.

In fact, Chancheng District in Foshan, Guangdong is already exploring the use of blockchain technology to achieve "zero errands" in government affairs. It can handle government affairs without leaving home, which has greatly improved Processing benefits.

Let’s talk about the second point: a decentralized system can be built so that multiple parties can trust each other. Before the emergence of blockchain, it was difficult for multiple entities to collaborate, especially online collaboration. This is why cross-border transfers generally take several days and are expensive, with fees of several percent. Because for cross-border transfers, different banks have different account books and use different systems. Therefore, it is often necessary for the personnel responsible for external clearing and settlement of the two banks to synchronize the account books with each other before the transfer can be successful.

Some people say that if everyone uses one system, then the question becomes, whose system should we use? Other companies don't trust whoever uses it, because whose system often has the authority to modify it, and the operating rights are in the hands of the other party, not to mention issues such as privacy.

But if the system is developed using blockchain, this problem can be solved very well, because everyone uses the same system, and the permissions between each node are consistent, and no one The subject can be changed at will.

In fact, in June 2018, Ant Financial had already used blockchain technology to achieve rapid cross-border remittances. It takes three seconds and the fee is extremely low and can be ignored.

This decentralized solution brought by blockchain can establish a collaborative relationship that is different from previous centralization and solve an insurmountable problem of centralization.problems and greatly improved efficiency.

If we extend from this direction, think about any company we are in, it will always be upstream or downstream of another company, and it will definitely exchange materials, funds, information, etc. with the other company. A series of interactions etc. Then you will find that many processes are often created for trust. For example, the information sent by the other party needs to be confirmed, and the materials sent by the other party need to be confirmed and inspected. Every time you make a new action with the other party, there will be constant questions. Confirmation, feedback. And these are the costs of trust.

But if you use the blockchain, after the data is generated, it is put on the blockchain, and all the upstream and downstream companies in the supply chain obtain the data, then a lot of data does not need to be confirmed repeatedly, so that It can greatly reduce the cost of trust. At the same time, because the data transmitted is credible. Once the data is trusted, the interaction between machines will reduce a lot of trouble in the future. (This is another big topic)

Blockchain technology is widely regarded as an important starting point for achieving a more secure Internet - its advantages mainly come from its technical principles and the current Internet structure. different. In this article we will introduce to you how blockchain can promote network security.

What is blockchain technology?

Blockchain technology is a decentralized distributed ledger system. You can put any digital assets into the blockchain, regardless of any industry. It uses a series of time-stamped immutable records to save information, managed by a cluster of computers. Different transactions can be tracked through these records, which are separated by blocks and connected by cryptographic chains. At the same time, the data does not belong to a certain computer or an individual, but is jointly owned by multiple users within the entire system.

Once the information is confirmed, the encoded data cannot be changed and will become a permanent block that is added to the chain formed by other blocks that have been verified. Initially this technology was designed for cryptocurrencies, but now we can see that blockchain technology has great potential in many areas, especially cybersecurity, as it can be used to prevent cyber attacks, data leaks, identity theft or Malicious transactions, keeping data private and secure.

As a lower-level technology, blockchain can provide beneficial solutions for different industries. Its main features are:

Blockchain has a democratized network with no central authority. It is public domain, so no single organization can enter the blockchain system to manipulate any information.

Blockchain is a decentralized system that does not belong to any one entity. Data in the blockchain system can be stored encrypted.

Anything stored in the blockchain is immutable, preventing human tampering or manipulation of the information. For example, with blockchain, it would be possible to hold a completely transparent election and instantlyproduces result. People can vote at home, and the results can be counted immediately.

Blockchain is transparent - anything built and stored in the blockchain is publicly accessible. The data stored inside can also be tracked, creating a higher standard of accountability for those who use the system.

How does blockchain technology promote network security?

Internet of Things and Edge Computing

With the development of Internet of Things and edge computing, more and more data Distributed across edge computing and storage devices for real-time, on-demand access, meaning data is processed and stored closer to the source. Blockchain provides a secure solution for IoT and Industrial IoT through tighter authentication, improved data attributes and flows, and more advanced record management systems.

In terms of IoT devices, blockchain technology, based on its decentralized architecture, can provide security for remote IoT devices and protect them from hacker attacks. Smart contracts can provide secure verification for transactions in a blockchain environment, and blockchain can be used to manage IoT activities.

Data access control

Because one of the original goals of blockchain was to enable public access, it has no access controls or restrictions. However, various industries now use private blockchain systems to ensure data confidentiality and secure access control. The blockchain’s full encryption ensures that data – whether part or all of it – cannot be accessed by outsiders, especially when it is being transferred.

DDoS Attack

The target of a Distributed Denial of Service (DDoS) attack is usually a server that is attacked by multiple infected computer systems, causing the system to fail through denial of service. slow down, eventually causing the system to overload or crash. If blockchain is integrated into a security system, the target computer, server, or network becomes part of a decentralized system that protects these machines from attacks.

Personal communication

By using a platform based on blockchain technology for communication, enterprises can obtain higher security, and the technology can resist malicious attacks. Whether in personal, business or highly confidential communications, consumers can gain the confidentiality of communications without fear of cyber attacks. Blockchain can handle public key infrastructure (PKI) better than ordinary encryption applications, so many companies now want to develop blockchain private communication applications.

Public Key Infrastructure

There is an increased focus on securing computers and online credentials, and blockchain technology can help in this regard. PKI relies on third-party certification authorities to secure communications applications, emails, and websites. These certification authorities that issue, revoke or store key pairs are often targeted by hackers, who usually use forged identities.attempt to access encrypted communications. When these keys are encoded on the blockchain, it minimizes the possibility of generating false keys or identity theft because the identity of the legitimate account holder is already verified on the application, making any intrusion, spoofing, or identity theft Thefts are instantly identifiable.

Domain Name System

Using the blockchain method to store the Domain Name System (DNS) can comprehensively improve security. Because it is no longer a single, risky target, it can prevent malicious activities by hackers from bringing down DNS service providers.

Blockchain, the future of network security

As we continue to deepen our understanding of blockchain, more and more people are investing in the application and research and development of blockchain technology. , this technology is slowly maturing. In the past two years, the application of blockchain in different industry scenarios has increased, as well as the country’s policy guidance on blockchain technology. Blockchain has changed dramatically and is no longer synonymous with cryptocurrency.

Blockchain technology may be born of cryptocurrency, but its value is by no means limited to cryptocurrency. Blockchain is a safe and reliable technology that, once integrated into mainstream security measures, can bring many practical benefits to advancing cybersecurity.

As hackers continue to create new and more sophisticated ways to steal and attack data, the threat to network security is intensifying, and blockchain technology is likely to become the forefront of network security in the next few years. To a certain extent, today’s blockchain is the future of network security.

My understanding is that blockchain is a technology, and the Internet is just a carrier or a communication channel for information integration. It should not be a post-Internet era.

Blockchain can be truly fair and open, and what has happened will not be tampered with when recorded.

Blockchain is decentralized, cannot be cracked, and its uniqueness is irreplaceable

『Lu』What impact does the emergence of blockchain technology have on the Internet

More often, blockchain technology will rely on the B/S, C/S structure of the Internet to achieve functional expansion, but overall it is still a supplement to the existing technology of the Internet. Most of the application scenarios currently envisaged by blockchain can be implemented using B/S and C/S structures, with higher efficiency and more mature technology.
Whether it is from the perspective of information transmission efficiency, resource consumption, or the evolution of the nervous system, blockchain cannot become the mainstream architecture of the Internet, let alone a subversive and revolutionary leader of the future Internet.

『撒』 What are the differences between blockchain and the Internet

Blockchain is essentially a decentralized ledger system that is decentralized, open, and information-free. With features such as tampering and programmability, it can be used as the underlying storage and transmission protocol of the Internet of Value. Blockchain is expected to lead us from personal trust and institutional trust to the era of machine trust. The consensus mechanism is the core of regional chain construction. Digital currency is just the beginning,Blockchain can change more, reshape the world's trust system, and solve many problems in the past where the cost of trust was too high.
As an analogy between blockchain and the Internet, they have one core difference: the values ​​of the underlying protocols and upper-layer applications of blockchain and the Internet are completely reversed. Mainly due to the two core characteristics of the blockchain:

The first characteristic is that zero-knowledge proof causes changes in data ownership. In other words, the user's personal data on the blockchain belongs to the user and does not need to be provided to the application and stored on a central server. Then Internet application layer services, such as BAT, the core supporting "data" behind the market value, have lost their original value in the blockchain field.
Another feature is the economic incentive model brought by tokens, which gives extremely high value to the underlying protocol. In the Internet era, no one paid for the http protocol, no one paid for sending and receiving emails, and no one paid for Google's search services.

『8』 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 has the characteristics of "unforgeable", "full traces left", "traceable", "open and transparent" and "collectively maintained". 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.
