A. What is the concept of blockchain

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

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.

(1) The essence of blockchain technology is extended reading:

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, thus ensuring recognition. The result is 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.

B. Popular explanation of blockchain technology. The essence is a distributed ledger

What is blockchain technology? Briefly explain what blockchain is. At the beginning of 2019, a new currency began to enter the ranks of digital currencies and gradually attracted the attention of many digital currency players.Light, that is blockchain technology. But some people found that there is really little information about it on the Internet. This not only caused many people to wonder, what is it and why is it so mysterious? Blockchain is the earliest basic technology of Bitcoin. It is currently being studied all over the world and can be widely used in various fields such as finance.

Basic Principles Edit

The basic principles of blockchain are not difficult to understand. Basic concepts include:

Transaction: an operation that causes a change in the status of the ledger, such as adding a record;

Block: records transactions and status results that occur within a period of time, is Consensus on the current account book status;

Chain: composed of blocks concatenated in order of occurrence, it is a log record of the entire state change.

If you think of the blockchain as a state machine, each transaction is an attempt to change the state, and the blocks generated by each consensus are the participants.

Explanation Editor

Explain in layman’s terms: If we assume that the database is an account book, then reading and writing the database can be regarded as an accounting activity. The principle of blockchain technology is to find the fastest and best bookkeeper within a period of time. This person will keep the books and then send this page of information in the ledger to everyone else in the entire system. This is equivalent to making changes to all records in the database and sending them to every other node in the entire network, so blockchain technology is also called a distributed ledger.

C. What is the most essential feature of the blockchain?

As the demand in the market is increasing, our merchants have already experienced a shortage of supply, so we As technical personnel, we will find more products for us to use, and blockchain is one of them. The most prominent and essential features of blockchain are:

Blockchain

Decentralization. Blockchain technology does not rely on additional third-party management agencies or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, each node realizes self-verification, transmission and management of information through distributed accounting and storage. Decentralization is the most prominent and essential feature of blockchain.

Openness. The foundation of blockchain technology is open source. In addition to the private information of the transaction parties being encrypted, the data of the blockchain is open to everyone. Anyone can query the blockchain data and develop related applications through the public interface. Therefore, the entire System information is highly transparent.

Independence. Based on consensus specifications and protocols (similar to various mathematical algorithms such as the hash algorithm used by Bitcoin), the entire blockchain system does not rely on other third parties. All nodes can automatically and securely verify and exchange data within the system without the need for any human intervention.

Security. As long as you cannot control 51% of all data nodes, you cannot arbitrarily manipulate and modify network data, which makes the blockchain itself relatively safe.Subjective and artificial data changes are avoided.

Anonymity. Unless required by legal regulations, technically speaking, the identity information of each block node does not need to be disclosed or verified, and information transfer can be carried out anonymously.

The Xueshuo Innovation Blockchain Technology Workstation under Lianqiao Education Online is the only "blockchain technology" approved by the "Smart Learning Workshop 2020- Xueshuo Innovation Workstation" carried out by the School Planning and Construction Development Center of the Ministry of Education of China. Professional” pilot workstation. The professional base is based on providing students with diversified growth paths, promoting the reform of the training model integrating professional degree research, production, and research, and building an applied and compound talent training system.

D. How to understand the essence of blockchain technology

The essence of blockchain is a distributed ledger. For example, a bank's system is also a ledger, with a complete set of information systems to store various transaction information such as deposits and withdrawals, loans, and exchanges. There are several keywords for blockchain:
1. Distributed: The ledger is not just stored in one place, but stored in many places.
2. General ledger: It is not necessarily the general ledger stored in a machine that can be determined through the network, but at least the general ledger can be obtained from the network.
3. Decentralization: "Distribution" is not general distribution, but decentralized distribution. No one can control or tamper with it, and its accounting rules are accounted for according to some designed mathematical methods. How to check and how to use it is all done according to a public method, so it is essentially a ledger.
Biying China took the lead in introducing blockchain into the crowdfunding industry, making crowdfunding more open, transparent and simple.

E. What technology is blockchain?

1. The reason why blockchain is popular is because its function is very practical. Blockchain can make information more fidelity . Blockchain technology can be applied to many fields and scenarios, including some social management scenarios, and it is necessary to further broaden the horizons of research and development of blockchain technology.
2. Blockchain is essentially a database technology, specifically a ledger technology. A ledger is a set of records that records changes in assets and transactions in one or more accounts. It is actually a database with the simplest structure. The running accounts we usually write down in small notebooks and the statements sent by the bank are all typical ledgers.
3. Blockchain is a distributed ledger with multi-party participation, and is called a technology "born to solve trust problems". The essential difference between the digital world and the physical world is that things in the physical world really exist and cannot appear or disappear out of thin air. However, data in the digital world can be deleted, altered or copied out of thin air without leaving any trace. But with blockchain technology, the digital world can be as real and trustworthy as the physical world.

F. What does blockchain technology essentially include

Essentially speaking, Jinwowo believes that blockchain technology mainly includes the following points:

1. Data storage: Break the monopoly of big data and promoteEnter the growth of big data
2. Data analysis: provide detailed data reports to help enterprises operate accurately
3. Data tracking: trace product and service processes to ensure the integrity of the enterprise
4. Data security: eliminate Illegal reselling of data, reshaping the rules of data circulation

G. Do you know what the essence of blockchain is and what is the principle of Bitcoin

Blockchain has been developed for some time today. Time has passed. During this period, people’s understanding of blockchain has experienced rapid changes.

The essence of blockchain is technology

Since we talk about the essence, what is the essence? The essence should be traced back continuously until it can no longer be traced back. Only then can what is obtained be called the essence. The essence of blockchain is a technology. Going back to the original starting point of the blockchain, when Bitcoin was first born, the problem it wanted to solve was the Byzantine Generals Problem. From a professional perspective, it meant how to achieve consistency in a distributed environment. . Blockchain technology is a combination of multiple technologies. It is naturally suitable for multi-party cooperation and can provide a trusted environment for multi-party cooperation.

Application of the non-tamperable characteristics of blockchain

Bitcoin’s technical principle P2P network

Bitcoin is a P2P computer Network, each network node stores all transaction records on the network. Generally speaking, any information can be recorded on one node plus several backups. All transaction records of the network are stored on each node, which results in the transaction records being visible to each node, and each node cannot independently modify the transaction records arbitrarily, thus forming a set of open and transparent transaction records.

H. What is the essence of blockchain

Blockchain is essentially a decentralized distributed database, a distributed data storage, and multi-center point-to-point transmission. , consensus mechanisms, encryption algorithms and other innovative application models in the Internet era.
In layman’s terms, the blockchain can be compared to a “ledger”. The traditional ledger is "centralized accounting" by one party. This new "accounting book" can be participated and shared by multiple parties on the Internet. Each participant can "accounting" and back up, and each backup is a "block". Each "block" is linearly connected to the next "block" in chronological order, and its structural characteristics make the record impossible to be tampered with and forged.
For example, if you are the one doing the accounting at home, and your parents give you a salary and let you record it in the account book, then because you are the only one keeping the accounting, you secretly spend more than ten yuan, Maybe they won't know, but now it's your parents who keep the accounts with you, so whether it's your father who wants to buy cigarettes secretly or you who want pocket money, every move will be clearly recorded in the account book.

I. What is the essence of blockchain

The essence of Jinwowo blockchain is actually to build a multi-center trust system in which everyone participates. superior,Enable trusted data sharing
