区块链去中心化好不好,区块链真的可以实现去中心化吗

区块链去中心化是一种全新的网络架构，它可以解决传统中心化网络的缺点，提高网络安全性和可靠性。它可以将数据存储在分布式的节点上，从而减少数据的中心化，消除信息的控制权，使网络更加安全可靠。因此，区块链是实现去中心化的有效方法。

共识机制是实现区块链去中心化的关键。它是一种分布式的共识协议，用于确认网络节点的交易历史，以及确认新节点加入网络的正确性。它是基于密码学，可以防止未经授权的交易，确保网络安全。最常见的共识机制是工作量证明（Proof of Work），它是一种比较耗时的算法，可以防止恶意节点攻击网络，保证网络的安全性。

智能合约是区块链去中心化的另一个重要概念。智能合约是一种分布式的自动执行程序，它可以自动执行交易，而不需要中介机构的介入。它可以提供更高的安全性和透明度，因为它的执行过程是可追溯的。智能合约可以用于实现各种分布式应用，比如金融服务、投票系统、游戏等，它可以替代传统的中心化服务，实现真正的去中心化。

分布式账本是区块链的基础，也是实现去中心化的核心技术。它可以将交易数据存储在分布式的节点上，而不是集中在一个中心服务器上，从而消除信息控制权。此外，它还可以提供高度可靠的数据安全性，因为它可以检测到任何未经授权的修改，保护数据不被篡改。因此，分布式账本是实现区块链去中心化的重要技术。

综上所述，区块链去中心化是一种新的网络架构，它可以解决传统中心化网络的缺点，提高网络安全性和可靠性。它的实现主要依赖于共识机制、智能合约和分布式账本，可以实现真正的去中心化，使网络更加安全可靠。

(i) Will you be caught if you are cheated when managing a blockchain platform?

It must be calculated based on the actual situation. If you are the manager of the platform, you will knowingly break the law. If you still insist on doing it despite the circumstances, then it must be a kind of fraud. Knowing the law and breaking the law will be punished with an additional penalty. Do you understand! , of course, criminal liability may not be that serious, but joint and several liability is definitely there. In the case of police interrogation, the first thing to identify is that you are the victim and you are just a small manager

㈡ Decentralized blockchain, why is the wallet "frozen"

< p>Companies such as metamask, opensea, and coinbase have hundreds and thousands of employees. Each of them is independent and decentralized, but these employees combined are subject to a single centralized corporate entity. Therefore, unified instructions will be adopted to block the specified address.

Provides all power and support for crypto activities, from mining machine manufacturers, to power companies, to node servers, computer rooms, broadband network providers, to crypto exchanges, media, and various crypto projects Companies, etc., are dispersed and decentralized, but together they are controlled by centralized powers like China and the United States, so they will also obey unified instructions.

China can control all domestic encryption activities, and the United States can control global encryption activities. If you are not convinced, the CIA will take the US military there in a minute.

"Freezing" a wallet address is like the country issuing a wanted warrant for a prisoner. Providing him with shelter is harboring criminals and is illegal. Yes, the frozen wallet can be traded privately. He transfers money to your address and you give him legal currency cash. But when his cryptocurrency is transferred to your wallet, your wallet will be frozen by the association. This kind of transaction is an illegal transaction, and you will bear the risk of joint crime. It is not difficult to track the specific location of these transactions, because all transactions are network communications, and the addresses of both parties will be exposed in the node server. Follow the network cable from bottom to top to the router, to the node server, to The computer room, and finally to the IDC and broadband service provider, and then from top to bottom, searching the communication log, it is easy to find the physical location of both parties to the transaction, and then arrest the person.

㈢ What is blockchain

[Definition]

Blockchain refers to collective maintenance through decentralization and trustlessness. A technical solution for a reliable database. This technical solution allows any number of nodes participating in the system to calculate and record all information exchange data in the system for a period of time into a data block (block) through cryptographic algorithms, and generate the fingerprint of the data block for linking ( chain) and check the next data block, all participating nodes in the system jointly determine whether the record is true.

Blockchain is a type of database similar to NoSQL (non-relational database).Such technical solutions are collectively referred to as not a specific technology. Blockchain technology can be implemented through many programming languages ​​and architectures. There are also many ways to implement blockchain. Common ones currently include POW (Proof of Work), POS (Proof of Stake), DPOS (Delegate Proof of Stake), etc.

The concept of blockchain was first proposed in the paper "Bitcoin: A Peer-to-Peer Electronic Cash System" by the author who calls himself Satoshi Nakamoto (Satoshi Nakamoto) individual (or group). Therefore, Bitcoin can be regarded as the first application of blockchain in the field of financial payments.

[Popular explanation]

No matter how big the system or how small the website, there is usually a database behind it. So who will maintain this database? Under normal circumstances, whoever is responsible for operating the network or system will maintain it. If it is a WeChat database, it must be maintained by Tencent's team, and Taobao's database must be maintained by Alibaba's team. Everyone must think that this approach is natural, but this is not the case with blockchain technology.

If we imagine the database as a ledger: Alipay, for example, is a typical ledger, and any change in data is an accounting type. We can think of database maintenance as a very simple accounting method. The same is true in the world of blockchain. Everyone in the blockchain system has the opportunity to participate in accounting. The system will select within a period of time, maybe within ten seconds, or maybe ten minutes, to select the person with the fastest and best accounting during this period. This person will do the accounting, and he will combine the changes in the database during this period with Changes in the ledger are recorded in a block. We can imagine this block as a page of paper. After confirming that the record is correct, the system will link (chain) the data fingerprint of the past ledger to this paper, and then This piece of paper is sent to everyone else in the entire system. Then the cycle starts over and the system looks for the next person who can do the accounting quickly and well, and everyone else in the system gets a copy of the entire ledger. This also means that everyone in this system has exactly the same ledger. This technology is called blockchain technology, also known as distributed ledger technology.

Since everyone (computer) has exactly the same ledger, and everyone (computer) has exactly the same rights, there will be no problem due to a single person (computer) losing contact or going down. The entire system collapses. Since there are exactly the same ledgers, it means that all data is open and transparent.Everyone can see the digital changes on each account. Its very interesting feature is that the data in it cannot be tampered with. Because the system will automatically compare, it will consider the account books with the largest number of the same number as the real account books, and the small number of account books with different numbers as others are false account books. In this case, it makes no sense for anyone to tamper with their own ledger, because unless you can tamper with most of the nodes in the entire system. If the entire system has only five or ten nodes, it may be easy to do, but if there are tens of thousands or even hundreds of thousands of nodes, and they are distributed in any corner of the Internet, unless someone can control most of the computers in the world , otherwise it would be unlikely to tamper with such a large blockchain.

[Elements]

Combined with the definition of blockchain, we believe that it must have the following four elements to be called a public blockchain technology. If it only has the first three points elements, which we will consider as private blockchain technology (private chain).

1. Point-to-point peer-to-peer network (peer-to-peer power, physical point-to-point connection)

2. Verifiable data structure (verifiable PKC system, non-tamperable database)

3. Distributed consensus mechanism (solve the Byzantine generals problem and double payment)

4. Nash equilibrium game design (cooperation is an evolutionarily stable strategy)
/>
[Characteristics]

Combined with the definition of blockchain, blockchain will realize four main characteristics: decentralized, trustless, Collectively maintained (Collectively maintained), reliable database (Reliable Database). And the four characteristics will lead to two other characteristics: open source (Open Source) and privacy protection (Anonymity). If a system does not possess these characteristics, it will not be considered an application based on blockchain technology.

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

Trustless: Each node participating in the entire system does not need to trust each other for data exchange. The operating rules of the entire system are open and transparent, and all data contents are also public. , therefore within the rule range and time range specified by the system, nodes cannot and cannot deceive other nodes.node.

Collectively maintain: The data blocks in the system are jointly maintained by all nodes with maintenance functions in the entire system, and these nodes with maintenance functions can be participated by anyone.

Reliable Database: The entire system will be divided into databases so that each participating node can obtain a copy of the complete database. Unless more than 51% of the nodes in the entire system can be controlled at the same time, modifications to the database on a single node are invalid and cannot affect the data content on other nodes. Therefore, the more nodes and stronger computing power participating in the system, the higher the data security in the system.

Open Source: Since the operating rules of the entire system must be open and transparent, for the program, the entire system must be open source.

Privacy protection (Anonymity): Since nodes do not need to trust each other, there is no need to disclose their identities between nodes. The privacy of each participating node in the system is protected. protected.

㈣ Everyone is talking about "decentralization", do you know what "decentralization" is?

Since the Internet era, around "centralization" and "decentralization" "The debate has never stopped. Now the rise of blockchain technology in the Metaverse era has brought a new interpretation to this debate.

·"Centralization" and "Decentralization"

To explain "decentralization", we must first mention its opposite - "centralization".

What is "centralization"?

"Centralization" means relying on the center to determine nodes. Nodes depend on the center. Nodes will not operate smoothly without the center.

To give a simple example, the shopping APP we commonly use now is a "centralized" platform, in which our shopping, transactions and other activities all depend on the shopping platform. The platform can obtain all the data of consumers and merchants, and can make certain decisions in the process. It has certain rights to influence the process, such as product push, etc. It is the center of the entire shopping process.

Because the center controls the data, the audience’s desire for “decentralization” is even more urgent. The so-called "decentralization" means to remove the center, disperse the power originally belonging to the center, and realize point-to-point communication between users.

What is "decentralization"?

"Decentralization" is the social relationship form and internal structure formed during the development of the Internet.The content generation form is a new online content production process compared to "centralization".

Compared with the early Internet era, "decentralization" refers to the transfer of power and operations from companies or governments to users. Content is no longer provided by professional websites or specific groups of people. It is the result of the joint participation and equal rights of all netizens. Anyone can express their opinions or create content online and co-produce information.

To put it simply: in a "decentralized" world, everyone will be a node, and anyone may become a center. No center will be permanent, but will be temporary, and no center will be mandatory for nodes.

·How to distinguish between "centralization" and "decentralization"?

From the perspective of vocabulary interpretation, the difference between the two is actually very obvious.

To give a simple example, "decentralization" is like attending a class reunion. Everyone is equal in the event and can freely choose to stay or leave. It will not affect the gathering activities.

"Centralization" is like participating in a music festival. During the event, everyone will follow the rhythm of the singer. Once the singer leaves the event, the music festival will also stop.

·Advantages of "decentralization"

1. Reduce risks

Compared with "centralization", all data are stored in one centralized On the central node, "decentralization" can better avoid infringement of network data from the outside world, such as hackers invading the network. In "centralized" nodes, hackers only need to attack the central node to destroy the entire network, but "decentralization" can "Centralization" is maintained in multiple central stages, so a hacker's attack on one of the nodes will not have much impact.

2. Decentralize the power of the center and avoid data monopoly

"Decentralization" can disperse the power of "centralized" companies, avoid the emergence of data monopoly, and allow users to Information privacy is guaranteed, without third-party intervention, and information leakage is avoided.

3. Save resources

Since the "decentralized" processing form is more concise, it will save more resources when a large number of data transactions are carried out simultaneously.

4. Autonomous efficiency

Due to "decentralization" using blockchain technology, point-to-point transactions are realized, ensuring high-efficiency and large-scale information interaction.

·Understanding misunderstandings

“Decentralization” does not mean that there is no center;Centers are diverse and anyone can become a center, and it won’t be permanent.

·Conclusion

“Decentralization”, as a typical feature of the blockchain, makes the operation of the blockchain independent of central processing nodes and realizes the distribution of data. Store, record and update. In this era of high-profile development of the metaverse, the charm of "decentralization" will inevitably become more prominent.

㈤ What does decentralization mean when the blockchain is broken, and how is its security?

Decentralization, for example, Taobao, which is usually used for shopping, is actually centralized. , whether it is selecting goods or paying for transactions, there is an inescapable platform for buyers and sellers. Alibaba, as the central platform, maintains the entire online shopping ecology. The so-called decentralization means that Alibaba is Get rid of the center and re-establish a new set of rules where everyone can jointly manage data and trade freely. There are many problems with centralization. In the centralized model, data are stored in the central server. Once this server is paralyzed, the entire network will be destroyed. Problems will arise. In addition, industry data is concentrated in a few giant companies. Due to opaque data management, once the data is leaked, the consequences will be catastrophic.

The advantage of decentralization is that everyone participates in data maintenance, and data information is no longer centralized, thus solving these problems. Therefore, decentralization can be said to be an unprecedented change in the Internet world. Everyone All can equally participate in the management and maintenance of data. The reason why blockchain is hailed as a trend is because of the fairness of decentralization.

Blockchain is a distributed database technology. Distributed technology mainly refers to storage architecture. The distributed architecture adopted by the blockchain not only stores ledger data on each node, but each node must contain the data of the entire ledger. This completely distributed architecture brings higher security than centralization. No one can destroy all nodes at the same time.

Will the decentralized wallet be closed?

It will not be closed. 1. The decentralized wallet is an account display software based on the blockchain, which means that the decentralized wallet itself does not store your data. It is just a software for receiving, transferring, and displaying your balance. So as long as you don't lose your private key (which can be understood as a password), your digital currency is very safe. Decentralized wallets, because users hold their own private keys and mnemonic words, do not rely on any third-party management, and no one else or even the official will know except the user themselves. 2. The private key is generally a string starting with 5, K, and L, and the mnemonic is generally a group of 12 words. The two are functionally consistent. Whoever has the private key or mnemonic phrase has control over the assets at the corresponding address and can restore the assets in the wallet. Therefore, private keys and mnemonic phrases should not be stored on networked devices. 3. If the private key or mnemonic phrase is lost, the wallet will not be able to help the user recover and the funds will be lost forever. Wallet backup, in layman’s terms, means to keep it safe for youThe password of the wallet ensures that it will not be stolen by others and that you will not lose it.
Extended information
1. "Decentralization" means gradually moving away from the centralized storage-directed access model of servers and clients, and replacing it with distributed storage models such as decentralized storage and grids. On the Internet, “decentralization” is also known as “division.” With the emergence of more simple and easy-to-use decentralized network services, the characteristics of Web 2.0 have become more and more obvious, such as the birth of Twitter, Facebook and other services that are more suitable for ordinary netizens, making it easier and more diverse to produce or contribute content to the Internet. ization, thereby increasing the enthusiasm of netizens to participate in contributions and lowering the threshold for content production. Ultimately, each netizen becomes a small and independent information provider, making the Internet flatter and content production more diversified.

3. Chinese name decentralization English name décentralisation Type technical term application web2.0 Overview The term decentralization or decentralization also refers to a land planning policy aimed at reducing the regional impact of Paris and surrounding areas proportion in development. Another policy of "industrial decentralization" was also mentioned. Especially in the mid-1950s, the state tried to encourage industry to go out of the Paris area and participate in "foreign aid construction" (développement exogène) in other provinces. This policy was later influenced by "local development" (développement). strong criticism from supporters of local). Compare it with a TV station: In the beginning, there was only one CCTV to transmit information. This was a center, like 1.0; then the rise of various local stations gathered a certain range of popularity, which formed multiple centers. The original center Weakened, like 2.0. The Ile-de-France region is home to virtually the majority of the population and economic activity. In the provinces, many places are in a worrying state of neglect. It was this situation that led to the introduction of ambitious land planning policies in the sixties, thanks to the Council for Land Planning and Regional Affairs (DATAR: la Délégation à l'Aménagement territoire et à l'Action Régionale) formation. This decentralization is implemented through the creation of a balanced metropolis.
