① What is blockchain technology and how does it change business and financial models

Blockchain technology is a distributed ledger technology. It allows multiple participants to jointly maintain a secure, transparent and immutable record on a decentralized network. Blockchain technology was originally designed for the digital currency Bitcoin, but is now widely used in many other fields.

The core features of blockchain technology include:

Decentralization: Blockchain has no central control agency, and data is distributed on various nodes in the network, which makes it decentralized. The centralization feature reduces the risk of single points of failure.

Transparency: Transaction records on the blockchain are public to all participants, and anyone can view these records. This helps increase trust and reduce the risk of fraud.

Immutable: Once a transaction is recorded on the blockchain, it cannot be easily modified or deleted. This guarantees data integrity and security.

Smart contracts: Transactions on the blockchain can be automatically executed to implement "smart contracts", which automatically execute corresponding operations when specific conditions are met. This helps simplify complex business processes and reduce costs.

Blockchain technology has had a profound impact on business and financial models, which is mainly reflected in the following aspects:

Reducing costs: Blockchain technology can reduce intermediary links and reduce costs. Transaction costs and operating costs. For example, by adopting blockchain for cross-border payments, remittance fees can be significantly reduced.

Improve efficiency: The automation and smart contract features of blockchain technology help improve the efficiency of business processes, reduce manual intervention, and reduce error rates.

Enhance trust: The transparency and non-tamperability of blockchain technology help to establish a reliable trust system, reduce the risk of fraud, and provide better protection for business activities.

Innovative business models: Blockchain technology has spawned many new business models, such as decentralized finance (DeFi), digital asset trading, supply chain finance, etc. These new business models have brought disruptive changes to existing industries.

In short, blockchain technology, as an emerging technical means, is gradually changing the landscape of business and finance. With the continuous development of technology and the in-depth promotion of applications, blockchain is expected to have a more extensive and far-reaching impact in the future

② How to understand the decentralization of blockchain technology

From an academic perspective, blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanisms, and encryption algorithms. Blockchain is essentially a decentralized database.

For example, if you are a woman, every time your boyfriend says something disgusting to you or promises to buy you something, you immediately record it and send it to all of your and his Best friends, classmates, colleagues, as well as various groups and circles of friends, he can no longer resistLai, this is called blockchain.

The core advantage of blockchain technology is decentralization. It can realize based on data encryption, time stamping, distributed consensus and economic incentives in a distributed system where nodes do not need to trust each other. The point-to-point transactions, coordination and collaboration of decentralized credit provide solutions to the common problems of high cost, low efficiency and insecure data storage in centralized institutions.

The application fields of blockchain include digital currency, certificates, finance, anti-counterfeiting and traceability, privacy protection, supply chain, entertainment, etc. With the popularity of blockchain and Bitcoin, many related top All domain names have been registered, which has had a relatively large impact on the domain name industry.

③ How blockchain empowers the transaction end

Blockchain technology itself is a distributed ledger technology, and its core features include decentralization, non-tampering, transparency, etc. These characteristics allow blockchain technology to be used to empower transactions. Here are a few examples:

Decentralized payment: With the help of blockchain technology, without any intermediaries, we can realize a global instant transfer method, making currency and virtual The asset trading process is more convenient, safe and reliable.

Smart contracts: Smart contracts are automated contracts based on the blockchain that can ensure trust between two participants without involving a third party, thereby reducing operating costs and risks. Smart contracts have the advantages of faster, lower cost, and more accurate execution, making the transaction process more efficient.

Decentralized exchange: By using blockchain technology, a decentralized exchange can be established where participants can trade directly and control their own digital assets in the process, unlike traditional transactions. In comparison, it can avoid the possibility of third-party intervention and improve the transparency and security of transactions.

Digital identity verification: Blockchain technology can be used to establish a secure, decentralized identity verification system, which will help improve users’ trust in digital asset transactions and reduce the risk of fake accounts , improve safety.

In short, blockchain technology can empower the transaction side by providing faster, more convenient, and safer transaction methods.

④ What are the characteristics of decentralization in blockchain technology?

The characteristics of decentralization in blockchain technology are decentralization, trustlessness, and collective maintenance.

1. Decentralization: There is no centralized hardware or management organization in the entire network. The rights and obligations between any nodes are equal, and the damage or loss of any node will not affect the entire system. operation. Therefore, the blockchain system can also be considered to have excellent robustness.

2. De-trust: There is no need to trust each other for data exchange between each node participating in the entire system. The operating rules of the entire system are open and transparent, and all data contents are also public, so Within the rule range and time range specified by the system, nodes cannot and cannotcannot deceive other nodes.

3. Collective maintenance: The data blocks in the system are jointly maintained by all nodes with maintenance functions in the entire system, and anyone can participate in these nodes with maintenance functions.

(4) Is the blockchain trading platform centralized? Further reading

Blockchain technology has never excluded supervision, and supervision nodes can conveniently Connect to any blockchain network. Due to the open and transparent nature of the blockchain, regulatory agencies can more easily monitor the transaction data of the entire system, and due to the tamper-proof nature of the blockchain.

Once a transaction occurs, it cannot be changed or deleted. It is impossible for data fraud to deceive supervision, which is more conducive to regulatory agencies' supervision of market behavior. It can be seen that blockchain will become an important tool for regulatory technology (RegTech).

⑤ The new generation of completely decentralized exchange Node Swap will be launched soon

It is reported that: it has attracted many international capitals The new generation of fully decentralized exchange Node Swap is about to be launched. Not long ago, Binance CEO Changpeng Zhao said that this is his most optimistic decentralized exchange. Why is this?

Nowadays, with the emergence of information transparency and sharing models, users have become more equal, joining hands with the public, with the purpose of co-creation, co-management, and sharing, and cooperating with users to jointly operate exchanges, which is the decentralization of Node Swap Purpose of the Exchange.

Lower the investment threshold in the encryption market, promote the organic integration of the encryption market and the traditional market, and create a good investment order in the encryption market.

⑥ Will blockchain technology really be a part of the post-Internet era?

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

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. As a result, proof of value and equity can be transmitted on the Internet.

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, 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? Whose to use?They don't trust any of them, because whoever's 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 establishes a collaborative relationship that is different from previous centralization, solves some insurmountable problems of centralization, and greatly improves 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 checked. 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 eviltransactions, 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 is possible to hold a completely transparent election with immediate results. 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 stricter 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

Using a platform based on blockchain technology for communication, enterprises canFor greater security, the technology protects against 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 issuing authorities, which issue, revoke or store key pairs, are often targeted by hackers, who often use fake identities to try 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 uniqueness is irreplaceable

⑦ Blockchain trading software

The software for blockchain trading is To provide a trading platform for digital currency enthusiasts and digital currency investors, we can look at the following aspects of selling potatoes

Legally, the country has promulgated the " After the September 4th ban,It is clearly proposed that domestic platforms are prohibited from providing digital currency trading platforms, and digital currency is essentially a virtual asset, and it is difficult to clearly define its value in law (generally speaking, the value of digital currency The price will be affected by many factors) Its value is floating

From the essence of the blockchain, the blockchain is actually a decentralized public ledger. Each user in the blockchain can be regarded as a node on the blockchain. The fundamental task of these nodes is to maintain the stability of the blockchain ledger and maintain consistency in the ledger data on each node.

From a security perspective, blockchain trading platforms are all in the form of software or websites and are vulnerable to network attacks to a certain extent.

To sum up, there is instability in the blockchain trading platform.
