㈠ What does the decentralization of the blockchain mean?
The decentralization of the blockchain refers to the form of social relations and content generated during the development of the blockchain. Form is a new online content production process compared to "centralization".
Blockchain is an important concept of Bitcoin. It is essentially a decentralized database. As the underlying technology of Bitcoin, it is a series of data blocks generated using cryptographic methods. , each data block contains a batch of Bitcoin network transaction information, which is used to verify the validity of its information (anti-counterfeiting) and generate the next block.
The blockchain is unified across the entire network, so it is logically centralized. From an architectural point of view, blockchain is based on a peer-to-peer network, so it has a decentralized architecture. From a governance perspective, blockchain uses consensus algorithms to make it difficult for a few people to control the entire system, so its governance is decentralized.
(1) Blockchain technology has decentralization and independence. Extended reading:
Characteristics of decentralization of blockchain:
Decentralization does not mean that there is no need for a center, but that the nodes can freely choose and determine the center. Simply put, centralization means the center determines the node. Nodes must rely on the center. Nodes cannot survive without the center.
In a decentralized system, anyone is a node, and anyone can become a center. No center is permanent, but is temporary, and no center is mandatory for nodes.
With the diversification of network service forms, the decentralized network model is becoming more and more clear and becoming more and more possible. After the rise of Web 2.0, the services provided by network service providers such as Wikipedia, Flickr, and Blogger are all decentralized. Any participant can submit content, and netizens can jointly create or contribute content.

㈡ Characteristics of Blockchain
< p>1. DecentralizationThe so-called decentralization means that because the blockchain uses distributed computing and storage, there is no centralized hardware or management organization, and the rights and obligations of any node are Equally, the data blocks in the system are jointly maintained by nodes with maintenance functions in the entire system.
2. Openness
The so-called openness means that the blockchain system is open. In addition to encrypting the private information of the transaction parties, the blockchain data is open to everyone. Public, anyone can query blockchain data through the public interface and develop related applications. The information of the entire system is highly transparent.
3. Autonomy
The autonomy feature of blockchain is based on specifications and protocols. Blockchain adopts consensus-based specifications and protocols (such as open and transparent algorithms) to enable all nodes in the system to operate in a trustless environment.Exchange data freely and securely, so that trust in "people" is replaced by trust in machines, and no human intervention can play a role.
4. Information cannot be tampered
Because of this, the stability and reliability of blockchain data are very high. Blockchain technology has fundamentally changed the centralized credit creation method, using mathematical principles rather than centralized credit institutions. To establish credit at low cost, birth certificates, real estate certificates, marriage certificates, etc. can be notarized on the blockchain, with a global central node, becoming something that is trusted by the world.
5. Anonymity
The so-called anonymity means that the exchange between nodes follows a fixed algorithm. The data interaction does not require trust, and the counterparty does not need to disclose its identity. The other party has trust in you, which is conducive to the accumulation of credit.
Lianxin is a blockchain application with tens of millions of member users. It has its own Quark blockchain as a public chain, qkibill open source wallet, and independent block browser. It is a completely independent A blockchain platform where users control their own data. Quark Chainchain’s innovative blockchain plus life service platform is committed to creating better blockchain services. The Chainchain Blockchain has the above characteristics and is a real blockchain chain project.
㈢ What are the differences and connections between blockchain and Bitcoin?
Blockchain technology is a new technology derived with the development of the Bitcoin economy. Blockchain technology can effectively The ground serves the Bitcoin economy, and they are interconnected. Bitcoin is a virtual currency that only circulates in a specific network economic environment. Blockchain technology can not only be applied to the economy, but can also be used in all walks of life. This is their difference.
Blockchain TechnologyBecause blockchain technology is still an emerging product, it does not yet have an accurate or definite definition and concept. Simply put, blockchain technology is a model for encrypted management of data, which can protect data to a large extent. Blockchain technology has the distinctive characteristics of decentralization, openness, independence, security and anonymity. Its characteristics are well adapted to today's requirements for information protection and information disclosure in all walks of life. On the one hand, it ensures data security and prevents data processing from being interfered by factors such as human subjective emotions and system failures. On the other hand, it is up to the individual data to decide whether to hide their details from the group to the greatest extent possible to achieve the purpose of protecting privacy.
At the same time, there is no doubt that blockchain technology is still in a preliminary state of development. Society's understanding of it is not deep enough, and scholars are still in the stage of continuous exploration. With the right application, blockchain technology willBring many positive impacts to society.
㈣ 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 cannot 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) Blockchain technology has decentralization and independence. Extended reading
Blockchain technology has never excluded supervision, and supervision nodes can be convenient Access 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).

㈤ What are the advantages of the application of blockchain technology in commodity anti-counterfeiting traceability
In the "blockchain era" “In the early days, 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, information on all aspects of the product 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 number of the product.Signatures and 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.
㈥ What is blockchain technology? Popular explanation of what blockchain is
Blockchain has been at the forefront since the end of October.
What is blockchain technology
Although blockchain has been around for more than ten years, many people still don’t know much about this technology.
Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms. From an application perspective, blockchain is a distributed ledger.
So, why is the blockchain called the blockchain?
Because the blockchain itself is a series of linked blocks, these blocks are filled with transaction records. The blocks are much like the records of a database. Every time data is written, it is Create a block. With the expansion of information exchange, one block continues with another, and the result is called a blockchain.
What are the characteristics of blockchain technology?
Simply put, blockchain has the characteristics of decentralization, openness, non-tampering, and anonymity.
1. Decentralization:
In the blockchain system, there is no center.
In the blockchain model, it is distributed accounting and storage. Each node self-verifies, transmits, and manages information. Each node is the center, which is decentralization.
2. Openness:
The blockchain system has the characteristics of openness. The data is open and anyone can query the blockchain data and data through the public interface. Develop related applications.
3. Information cannot be tampered with:
In the blockchain system, once the data is written, the tampering cannot be undone unless 51% of all data nodes are controlled. Forge a record that does not exist. Therefore, blockchain technology has a certain degree of security.
4. Privacy and anonymity:
The cryptography technology in the blockchain can effectively achieve identity concealment.
The identity information of each node does not need to be disclosed or verified, and information transfer can be done anonymously. It can only be accessed with the authorization of the data owner, thus ensuring data security and personal privacy.
Xiao Li lent 10,000 yuan to Xiao Wang. Xiao Li found two people in common and Xiao Bai to prove it. This accounting model is a centralized accounting model, and Xiaobai is the center.
However, a year later, when Xiao Li wanted to get the money back, Xiao Wang Shikou denied that he had lent him the money. It turned out that Xiao Wang introduced Xiao Bai’s girlfriend to his company. a job.
This is the disadvantage of centralized accounting.
Xiao Li learned a lesson and gained wisdom. In the future, when someone asked him to borrow money, he said on WeChat in the village that I would lend so-and-so how much money. In this way, everyone in the village knew that Xiao Li How much money did Li lend to whom?
In this way, when Xiao Li asks for debt again in the future, the other party will not deny the issue, because a consensus mechanism has been established in the minds of the people in the village: How much did you borrow from Xiao Li? .
This is the advantage of decentralized accounting.
Because after all, there are many people to testify about this transaction. If it seems to be a fraud, it will be unless more than half of the people in the village are bought. However, the price is very high.
In fact, these characteristics of the blockchain are all to solve the problem of "trust". The rich application scenarios of the blockchain are also based on the blockchain's ability to solve the problem of information asymmetry. At the same time, Blockchain also helps achieve collaborative trust and consistent action among multiple entities.
What are the applications of blockchain?
In addition to digital currency, there are many application scenarios of blockchain.
1. Medical field
Blockchain helps realize smart medical care, such as going to the hospital to see a doctor. Through the blockchain model, the patient’s medical status, cases, treatment status, etc. are all Clearly visible, saving a lot of medical resources.
2. Copyright field
Blockchain can prove the authenticity and uniqueness of the copyright of works, from the birth to the transfer of audio, video, pictures, text and other works. Can be tracked and recorded, and form tamper-proof information.
3. Logistics field
After applying blockchain in the logistics field, goods can be traced from production to consumption.
4. Food safety
Is blockchain used for food safety? via blockchainTraceability makes it easy to trace the past and present life of their food.
5. Securities trading
For example, traditional securities trading requires the coordination of multiple institutions to complete, while the blockchain system can independently complete one-stop transactions. This service can make securities trading simpler and faster.
However, many people have big misunderstandings about blockchain. The biggest misunderstanding is: blockchain = Bitcoin
In fact, blockchain and Bitcoin is not the same thing. Blockchain is the underlying technology of Bitcoin, and Bitcoin is the first application of blockchain.
㈦ What does the decentralization of the blockchain mean?
The decentralization of the blockchain refers to the form of social relations and content generation formed during the development process of the blockchain. It is a new online content production process compared to "centralization".
Blockchain is an important concept of Bitcoin. It is essentially a decentralized database. As the underlying technology of Bitcoin, it is a series of data blocks generated using cryptographic methods. , each data block contains a batch of Bitcoin network transaction information, which is used to verify the validity of its information (anti-counterfeiting) and generate the next block.
