Ⅰ What is the difference between regional chain and blockchain?

Blockchain is not a single individual, but connects many block structures together to form a chain structure. Each block is then connected to form a specific collection or area. So there is actually no difference between blockchain and regional chain. The term regional chain is actually another expression of blockchain. Blockchain technology is the underlying technology. Without the operation and management of any centralized organization, it has been running very stably for many years without any problems. Therefore, some people noticed its underlying technology and extracted the technology abstractly, calling it Blockchain technology, or distributed ledger technology. When we search for regional chains, we will automatically jump to the search results page of blockchain, so we can list blockchain and blockchain as synonyms.
Extended information
1. What is blockchain?
Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. The so-called consensus mechanism is a mathematical algorithm that establishes trust and obtains rights and interests between different nodes in the blockchain system
Blockchain is a very important technology. Huobi.com cooperates with the Internet Finance Laboratory of Tsinghua University PBC School of Finance , the "2014-2016 Global Development Research Report" released by Sina Technology mentioned that blockchain is the underlying technology and infrastructure. Essentially a decentralized database. Blockchain is a series of data blocks generated using cryptographic methods. Each data block contains information about a network transaction and is used to verify the validity of the information (anti-counterfeiting) and generate the next block.
In a narrow sense, blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable and non-forgeable. Ledger.
Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses A new distributed infrastructure and computing method that uses smart contracts composed of automated script codes to program and operate data.
Blockchain _ The original blockchain is a decentralized database that contains a list called blocks, with continuously growing and neatly arranged records. Each block contains a timestamp and a link to the previous block: Blockchains are designed so that data is immutable—once recorded, the data in a block is irreversible.
The design of blockchain is a protection measure, such as (applied to) highly fault-tolerant distributed computing systems. Blockchain makes hybrid consistency possible. This makes blockchain suitable for recording events, titles, medical records and other activities that require data collection, identity management, transaction process management and provenance management. Blockchain has huge potential for financial disintermediation and has a huge impact on leading global trade.
2. What is a regional chain?
The words "region chain" and "blockchain" are only different in one word. Do they have the same meaning? Let's take a look at the meaning of the words block and domain. A block can be understood as a part of the whole, and a domain refers to a specific area or a specific whole.
Blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and is a cryptographically guaranteed distributed ledger that cannot be tampered with or forged.
Broadly understood, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, and uses cryptography to ensure the security of data transmission and access. A new distributed infrastructure and computing method that uses smart contracts composed of automated script codes to program and operate data.

II Blockchain and Edge Computing What is Blockchain and Edge Computing Analysis

1. Blockchain: Blockchain is a concept of Bitcoin. It uses a block chain data structure to verify and store data, and uses a distributed node consensus algorithm to generate and update data. Utilize cryptographic methods to ensure the security of data transmission and access. It is a new distributed infrastructure and computing method that uses smart contracts composed of automated script codes to program and operate data. It is essentially a disintermediated database.

2. Edge computing: Edge computing is the ability to use an integrated platform of network, device computing, storage, etc., close to the source of data to provide corresponding services nearby. The main feature of edge computing is to provide services based on a regional model near the data end. Since the demand end and the service provider end are very close to each other geographically, it is easier to provide fast and high-quality services, thus gaining popularity from Internet companies. .

3. Edge computing does not actually appear in the past few years. As early as 2003, IBM cooperated with content distribution network CDN and cloud service provider AKAMAI in edge computing. , and edge computing has also begun to cautiously carry out large-scale applications in recent years with the development of blockchain and 5G technology. Since edge computing needs to connect many devices scattered around, it also needs to form a distributed network. This This structure is similar to the decentralization of blockchain, so in many cases, edge computing and blockchain can be well combined.

III Briefly explain what blockchain is

Blockchain is a term in the field of information technology. 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.

On January 10, 2019, the Cyberspace Administration of China released the "Blockchain Information ServicesManagement Regulations". On October 24, 2019, during the 18th collective study session of the Political Bureau of the CPC Central Committee, General Secretary Xi Jinping emphasized that “blockchain should be used as an important breakthrough for independent innovation of core technologies” and “accelerate the development of blockchain technology and industrial innovation.” . "Blockchain" has entered the public eye and become the focus of society.

On December 2, 2019, the word was selected into the top ten buzzwords of 2019 by "Biwenqiezi".

Blockchain financial applications:

Since 2016, various Major financial giants have also taken notice and launched blockchain innovation projects one after another to explore the possibility of applying blockchain technology in various financial scenarios. In particular, Puyin Group took the lead in pioneering the “blockchain+” standard digital currency.

The standard digital currency is an asset that has been identified, evaluated, confirmed, insured, etc. by a third-party organization and written into the blockchain through rigorous digital algorithms to form a standard correspondence between the asset and the digital currency. relationship, called a standard digital currency.

In order to realize the great leap forward development of blockchain finance, in order to promote the new development of China's economy, accelerate the circulation of global assets, and realize the dream of rejuvenation that generations of people have been striving for, Puyin Group will Puyin Blockchain Finance Guiyang Strategy Release Ceremony was held in Guizhou on the 9th;

At the meeting, the digital circulation of assets through blockchain, the blockchain financial transaction model, and the relationship between blockchain services and blockchain services will be discussed. The application of social public industries will be discussed. This conference will mark the beginning of the application of blockchain finance and the transformation and development of a new financial ecosystem.

IV What is Blockchain

Concept: Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm.

The essence of the blockchain is a distributed public ledger. Anyone can verify this ledger, but no single user can control it. Participants in a blockchain system jointly maintain a ledger: it can only be modified according to strict rules and consensus.

The development of blockchain has gone through three stages:

1. Incubation period: 2009-2012, the economic form was dominated by Bitcoin and its industrial ecology.

2. Embryonic period: The period is from 2012 to 2015. Blockchain entered the public eye with Bitcoin, new wallet payment and remittance companies appeared, and the blockchain economy spread to the financial field. The underlying technology of blockchain continues to innovate. Blockchain technology is divorced from the Bitcoin system.

3. Development period: In 2016, industry applications began to be explored, and a large number of blockchain startups emerged. The popularity of ICO in 2017 brought unprecedented attention to blockchain.

(4) Extended reading on the difference between blockchain cdn:

Three characteristics of three blockchains:

1. The core idea of ​​the blockchain is decentralization: in the blockchain system, the rights and obligations between any nodes are equal, and all nodes have the ability to vote with computing power. This ensures that the recognized result is the result recognized by more than half of the nodes. Even if it suffers a severe hacker attack, as long as the number of nodes controlled by the hacker does not exceed half of the total number of global nodes, the system will still be able to operate normally and the data will not be tampered with.

2. The biggest disruption of blockchain lies in the establishment of credit: in theory, blockchain technology can make WeChat Pay and Alipay no longer valuable. "The Economist" gave a vivid metaphor to the blockchain: simply put, it is "a machine that creates trust." Blockchain allows people to collaborate without trusting each other and without a neutral central authority. Combating counterfeit currency and financial fraud will no longer be needed in the future.

3. The collective maintenance of blockchain can reduce costs: In a centralized network system, the maintenance and operation of the system rely on the operation, maintenance and operation of platforms such as data centers, and costs cannot be omitted. Anyone can participate in the nodes of the blockchain. While participating in the recording, each node also verifies the correctness of the recording results of other nodes, which improves maintenance efficiency and reduces costs.

In one sentence, blockchain touches money, trust and power, which are the fundamental foundations on which human beings rely for survival.

IV What is the difference between regional chain and blockchain? It turns out to be this

1. Blockchain is a combination of data blocks that are connected sequentially in chronological order. A chained data structure and a cryptographically guaranteed distributed ledger that cannot be tampered with or forged.

2. Broadly understood, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, and uses cryptography to ensure data Security of transmission and access, a new distributed infrastructure and computing method that uses smart contracts composed of automated script codes to program and operate data. Summary: From the above description of what a blockchain is, we can see that a blockchain is not a single individual, but a number of block structures connected together to form a chain structure.

3. Then the connection of each block will also form a specific whole or area. Therefore, there is actually no difference between blockchain and regional chain. The term “regional domain chain” is actually another description of blockchain. When we search for regional chains, we will automatically jump to the search results page of blockchain, so we can list blockchain and blockchain as synonyms.

VI What is digital currency blockchain

1. Blockchain is a ledger that records digital currency transactions
Take Bitcoin as an example. It has no physical form, but It exists in a special ledger. All Bitcoin transactions are recorded in the ledger. Through the transaction records, we can calculate the number of Bitcoins owned by each user, such asIf a person owns Bitcoin, it means that transaction records related to him can be found in the ledger.
The ledger mentioned here is a piece of software, which we can download from the official Bitcoin website, and the underlying technology used in this software is the blockchain. To facilitate understanding, we usually say that the blockchain is the ledger.
The reason why blockchain is used as the underlying technology of the ledger is to achieve the decentralization of digital currency. It can be said that the starting point for a series of problems encountered by digital currencies and the solutions provided comes from decentralization.
2. Blockchain is a technology that ensures the safe use of digital currencies. Everyone knows that blockchain technology has two major characteristics: encryption and non-tamperability, which can reduce the probability of errors during the use of digital currencies. reduced to 0. Since digital currencies have higher requirements for encryption, blockchain technology must be used to support them. Currently, not only many industries in our country are using blockchain technology, but many foreign countries are also actively using blockchain technology. Blockchain technology.
[Extended information]
Blockchain is the underlying technology of digital currency, and Bitcoin is the first successful application of blockchain.. To understand this problem, we must first recognize the facts: not all blockchains require Issuing digital currency, currently our country strongly supports "coinless blockchain". Generally speaking, public blockchain, that is, public chain, needs to issue tokens as "rewards" to motivate users and maintain system operation, while ordinary blockchain , often called a consortium chain, can or cannot be issued. Private blockchains are mostly used for company internal audits and generally do not need to issue coins. The following is a detailed explanation of the differences between the three blockchains:
1. Public block Chain: A blockchain in which anyone in the world can read and send transactions for validity confirmation, and anyone can participate in its consensus process. Bitcoin and Ethereum are typical applications of public blockchains. Public blockchains are a global Distributed blockchain, blockchain data is open, user participation is high, and it is easy to produce network effects, easy to apply and promote. Therefore, this kind of blockchain operation relies heavily on the incentive mechanism, Bitcoin Tokens such as Ethereum and Ethereum are used as "rewards" for incentives, so public chains need to issue tokens to maintain their own development and ecology.
2. Community Blockchain (Alliance Chain): It means that the participation of nodes in the blockchain is selected in advance. There are usually good network connections and other cooperative relationships between nodes. The data on the blockchain can be open It can also be internal. For partial distribution, we can regard it as "partial decentralization". Each alliance in the chain has its own centralized management. For example, R3CEV of more than 40 banks is a typical alliance chain. Chains usually don’t require a lot of money, but there are also individual alliance chains that choose to send money to motivate members within the alliance to contribute, so there are no restrictions on the chain.
3. Private blockchain: refers to a node with only a limited scope of participation, such as a specific organization's own users, strict permission management for data access and use... Completely privateWrite permissions in the blockchain are only in the hands of the participants, and read permissions can be open to the outside world or restricted to any extent. They are currently mainly used for internal audit work of the company. Therefore, private chains do not need to issue currency and are not decentralized. The characteristic is a centralized management mechanism.

Ⅶ What is the relationship and difference between edge computing and cloud computing?

Edge computing refers to the integration of network, computing, storage, and application core capabilities at the edge of the network close to the source of things or data. An open platform that provides edge intelligence services nearby to meet the key needs of industry digitalization in terms of agile connection, real-time business, data optimization, application intelligence, security and privacy protection.
Fog computing, like cloud computing, is very vivid. Clouds float in the sky, high above, out of reach, and deliberately abstract; while fog is realistically accessible, close to the ground, and right next to you and me. Fog computing is not composed of powerful servers, but of computers with various functions that are weaker and more dispersed. It has penetrated into factories, cars, electrical appliances, street lights and various supplies in people's material lives.
The core idea of ​​cloud computing is "centralization". It is envisioned that in the future, the terminals themselves will no longer need high-performance CPU, GPU, and storage space. All terminals will be connected to the cloud, and every mirror and every mobile phone will be connected to the cloud. They are all entrances to the cloud. They do not (do not need) to calculate and process data themselves, and all are handed over to the computing center in the cloud for processing. The access terminal is only input and output. This idea is very good, but it is still a very distant goal for a long time to come.

The most practical and practical solutions at this stage are edge computing (front-end and back-end hybrid computing), decentralized distributed computing, and fog computing. All terminals can become distributed computing nodes. , all terminals in a blockchain have parallel permissions. This design idea is currently being applied in the development of cloud desktops.
