根据网络范围区块链分类包括哪些,根据网络范围区块链分类包括什么

根据网络范围区块链分类，主要包括公有链、联盟链和私有链三种。以下将对三种类型的区块链进行介绍：

公有链，也叫做开放链，是指任何人都可以参与发起，参与使用的区块链网络。它是一种去中心化的、开放的、公共的、任何人都可以参与的区块链网络。它支持自由的参与者参与，允许任何人来参与网络的构建和使用，而不需要任何中介机构的参与。常见的公有链有比特币、以太坊等。

联盟链，也叫做受限链，是指只有特定的一群参与者才能参与网络的构建和使用的区块链网络。它是一种更加安全的区块链网络，它有一个特定的参与者群体，只有这些参与者才能参与网络的构建和使用。它的参与者可以根据需要设置不同的访问权限和规则，从而更好地保护网络的安全。常见的联盟链有Hyperledger Fabric、R3 Corda等。

私有链，也叫做私有链，是指只有特定的一个或者少量的参与者才能参与网络的构建和使用的区块链网络。它是一种非常安全的区块链网络，只有特定的参与者才能参与网络的构建和使用，这种参与者可以是一个公司、一个机构或者一个小群体。它可以根据需要设置不同的访问权限和规则，从而更好地保护网络的安全。常见的私有链有Multichain、Quorum等。

以上就是根据网络范围区块链分类，主要包括公有链、联盟链和私有链三种，常见的公有链有比特币、以太坊等，常见的联盟链有Hyperledger Fabric、R3 Corda等，常见的私有链有Multichain、Quorum等。

㈠ What categories can blockchain technology be roughly divided into at present?

As far as the known application classification of blockchain technology is concerned, Jinwowo Group believes that it can be roughly divided into There are three major categories:
1-Public blockchain; it refers to a blockchain that anyone can read, send transactions to confirm validity, and anyone can participate in its consensus process and jointly maintain the public area. Blockchain data is safe, transparent, and cannot be tampered with. For example, Bitcoin is represented
2-Community blockchain; also known as alliance chain, it means that participating blockchain nodes are selected in advance, and there are usually good network connections and other cooperative relationships between nodes;
Community blockchain is a practical application scenario that combines blockchain with physical goods, such as Domenech Jewelry’s Ubei model
3-Private blockchain: The participating nodes have only a limited scope and data access And use has strict permission management. Write permission is only in the hands of participants, and read permission can be opened to the outside world.

㈡ Classification of blockchains

Currently blockchains are divided into three categories, among which hybrid blockchains and private blockchains can be regarded as: generalized private chains, public blocks chain public blockchain. This means that any individual or group in the world can send transactions, the transactions can be effectively confirmed by the blockchain, and anyone can participate in its consensus process. Public blockchain is currently the earliest blockchain and the most widely used blockchain. Each virtual digital currency of the Bitcoin series is based on a public blockchain, and there is only one blockchain in the world corresponding to this currency.
Extended information
1. Industrial blockchain industry blockchains: multiple pre-selected nodes in the group are designated as bookkeepers, and the generation of each block is jointly decided by all pre-selected nodes (pre-selected nodes participate in the consensus process), others Access nodes can participate in transactions but do not interfere with the accounting process (essentially, it is managed bookkeeping, but it becomes distributed bookkeeping). How many pre-selected nodes and how to determine the bookkeeper for each block become the main risk points of the blockchain ), anyone else can make limited queries through the blockchain’s open API. Private Blockchain Private Blockchain ((privateblockchains)): Only the general ledger technology of the blockchain is used for accounting. It can be a blockchain with exclusive written permission from a company or individual. This chain is not much different from other distributed storage solutions. At present (December 2015), conservative giants (traditional finance) want to try private blockchains, while the applications of public chains, such as Bitcoin, have been industrialized, and the application products of private chains are still being explored. Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms. Blockchain is an important concept of Bitcoin. Essentially, it is a decentralized database.
2. At the same time, as the underlying technology of Bitcoin, it is a series of data blocks associated with encryption methods. Each data block contains a batch of Bitcoin network transaction information to verify the validity of its information.(anti-counterfeiting) and generate the next block. In fact, the word blockchain does not appear in the original English Bitcoin white paper, but appears in blockchain. In the earliest Bitcoin white paper, blockchain was translated as blockchain. This is the time when the Chinese word "blockchain" first appeared. The Cyberspace Administration of China issued the "Blockchain Information Service Management Regulations" on January 10, 2019, which came into effect on February 15, 2019. In a narrow sense, a blockchain is a chained data structure that combines data blocks in chronological order, and a tamper-proof and forgery-proof distributed ledger guaranteed by cryptography. Broadly speaking, blockchain technology is a new distributed infrastructure and computing method that uses blockchain data structures to verify and store data, distributed node consensus algorithms to generate and update data, and cryptography to Ensure the security of data transmission and access, using smart contracts composed of automated script code to program and operate data.

㈢ The classification of blockchain according to the network includes

Legal analysis: In this application stage, people try to use blockchain to subvert the lowest level protocol of the Internet. It also attempts to apply blockchain technology to the Internet of Things to bring the entire society into the era of intelligent Internet and form a programmable society. According to the scope of the network, it can be divided into public chain, private chain and alliance chain. The so-called public means that it is completely open to the outside world, and anyone can use it at will. There is no permission setting, and there is no identity authentication. Not only can you participate and use it at will, but all the data that occurs can be viewed at will, and it is completely open and transparent.

Legal basis: "Blockchain Information Service Management Regulations" Article 2 Those who engage in blockchain information services within the territory of the People's Republic of China must comply with these regulations. If laws and administrative regulations provide otherwise, such provisions shall prevail. The term “blockchain information services” as mentioned in these regulations refers to the information services provided to the public through Internet websites, applications, etc. based on blockchain technology or systems.

㈣ The technical classification of blockchain mainly includes

1. Public chain, no official organization, no management organization, and no central server. Participating nodes freely access the network in accordance with the rules of the system. There is no control and the nodes work based on a consensus mechanism. (Subversive: absolutely trustworthy and open)

㈤ What are the classifications of blockchain and what is the structure of the blockchain?

The concept of blockchain has been described as It is quite popular, it comes from the implementation of cryptocurrencies such as Bitcoin, but now this technology has been gradually used in various fields. So do you know what the classifications of blockchain are? What is the structure of blockchain? Let’s follow us to find out more.
What are the classifications of blockchain?
1. Public Blockchains (PublicBlockChains)
Public Blockchain means: any individual or group in the world can send transactions, and the transactions can be effectively confirmed by the blockchain, and anyone can participate its consensus process. public blockChain is the earliest blockchain, and it is also the most widely used blockchain at present. The virtual digital currencies of all major bitcoins series are based on public blockchains. There is only one blockchain corresponding to this currency in the world. .
2. Consortium (Industry) Blockchain (ConsortiumBlockChains)
Industry Blockchain: Multiple preselected nodes are designated within a certain group as bookkeepers, and the generation of each block is jointly performed by all preselected nodes. Decision (pre-selected nodes participate in the consensus process), other access nodes can participate in transactions, but do not participate in the accounting process (essentially still managed accounting, but become distributed accounting, how many slag points are pre-selected, how to decide each The bookkeeper of each block becomes the main risk point of the blockchain), and anyone else can conduct limited queries through the open API of the blockchain.
3. Private Blockchain (privateBlockChains)
Private Blockchain: Only uses the general ledger technology of the blockchain for accounting. It can be a company or an individual, and has exclusive access to the writing of the blockchain. With access permissions, this chain is not much different from other distributed storage solutions. At present (Dec2015), conservative giants (traditional finance) want to experiment with private blockchains, while public chain applications such as Bitcoin have been industrialized, and private chain application products are still being explored.
4. Sidechain (Sidechain)
Sidechain is a blockchain used to confirm data from other blockchains. Through the two-way peg (TwoWayPeg) mechanism, various assets such as Bitcoin and Ripple coins can be Transfers are realized on different blockchains at a certain exchange rate.
What is the structure of blockchain?
1. Basic network layer: The basic network layer consists of a data layer and a network layer. The data layer includes underlying data blocks and related data encryption and timestamp technologies; the network layer includes distributed networking mechanisms, Data dissemination mechanism and data verification mechanism, etc.
2. Intermediate protocol layer: The intermediate protocol layer consists of a consensus layer, an incentive layer, and a contract layer. The consensus layer mainly includes various consensus algorithms of network nodes; the incentive layer integrates economic factors into the blockchain technology system. , mainly including the issuance mechanism and distribution mechanism of economic incentives; the contract layer mainly includes various scripts, algorithms and smart contracts, which is the basis of the programmable features of the blockchain.
3. Extension layer: This layer is similar to a computer driver and is designed to make blockchain products more practical. There are currently two categories. One is various trading markets, which are important channels for exchanging fiat currencies for cryptocurrency. They are simple to implement, get money quickly, and have low costs, but the risks are also high. The second is the expansion implementation in a certain direction. For example, based on the Yishu side chain, it can provide customized services for third-party publishing organizations, forum websites and other content producers.
4. Application service layer: As the most important link in the blockchain industry chain, the application service layer includes various application scenarios and cases of blockchain, including programmable currency, programmable finance and programmable society.
The above isWhat are the blockchain categories that the editor brings to you? What is the structure of blockchain? all content.

㈥ There are several classifications of blockchain

1. Decentralization
Due to the use of distributed computing and storage, there is no centralized hardware or management organization, and any The rights and obligations of nodes are equal, and the data blocks in the system are jointly maintained by nodes with maintenance functions in the entire system.
2. Openness
The system is open. In addition to the private information of the transaction parties being encrypted, the blockchain data is open to everyone, and anyone can query the blockchain through the public interface. Data and development related applications, so the entire system information is highly transparent.
3. Autonomy
Blockchain adopts consensus-based specifications and protocols (such as a set of open and transparent algorithms) to enable all nodes in the entire system to exchange data freely and securely in a trustless environment. , so that trust in "people" is changed to trust in machines, and any human intervention has no effect.
4. Anonymity
Since the exchange between nodes follows a fixed algorithm, the data interaction does not require trust (the program rules in the blockchain will judge whether the activity is valid by itself), so the counterparty does not need to Making the other party trust you by disclosing your identity is very helpful for the accumulation of credit.
Outstanding advantages:
Information cannot be tampered
Once the information is verified and added to the blockchain, it will be stored permanently. Unless more than 51% of the nodes in the system can be controlled at the same time, otherwise Modifications to the database on a single node are invalid, so the data stability and reliability of the blockchain are extremely high.
(6) Classification of blockchain based on network scope includes extended reading:
Blockchain originated from Bitcoin, two weeks after the collapse of Lehman Brothers, which marked the starting point of the last financial crisis, in November 2008 On the 1st, a person claiming to be Satoshi Nakamoto published the article "Bitcoin: A Peer-to-Peer Electronic Cash System", which elaborated on P2P network technology, encryption technology, timestamp technology, blockchain technology, etc. The architectural concept of the electronic cash system marked the birth of Bitcoin.
Two months later, the theory came into practice, and on January 3, 2009, the first Bitcoin genesis block with serial number 0 was born. A few days later, block number 1 appeared on January 9, 2009, and was connected to the genesis block number 0 to form a chain, marking the birth of the blockchain.
In recent years, the world's attitude towards Bitcoin has been ups and downs, but blockchain technology, one of the underlying technologies of Bitcoin, has received increasing attention. In the formation process of Bitcoin, blocks are storage units one by one, recording all communication information of each block node within a certain period of time.
The links between each block are realized through random hashing (also called hash algorithm). The latter block contains the hash value of the previous block. With the expansion of information exchange, aBlocks follow one block after another, and the result is called a blockchain [3].

㈦ The technical classification of blockchain mainly includes

including public chain, alliance chain, private chain and so on. The emergence of these lead-up technology classifications is mainly to solve different usage scenarios and needs of the public chain. The public chain is relatively transparent, and the security is jointly maintained by network participants. The delay and high handling fee cost caused by its decentralization cannot be tolerated. On the other hand, consortium chains and private chains have more flexible access control and faster network speeds. Blockchain is a decentralized, digital ledger technology that is secure, transparent, and cannot be tampered with.

What are the different types of blockchains

The different types of blockchains are as follows

1. Divided by degree of openness: public chain, alliance chain, Private chain

2. Divide by application scope: basic chain, industry chain
There is a saying that currency is about consensus, and chain is about ecology.

3. Divide by original program: original chain, forked chain
This division may be more niche, and maybe there is such an understanding

Four , divided according to the degree of independence: main chain, side chain
There is another way to divide the blockchain according to whether the blockchain is independent enough.

5. Division by hierarchical relationship: parent chain, sub-chain
The last division method is also relatively niche, and let’s give a simple definition.
