区块链白话解释,区块链大白话解释

近年来，区块链技术已经成为一种热门话题。区块链的概念可能听起来抽象，但它的确是一项重要的技术。那么，什么是区块链？大白话来解释，区块链就是一个由一系列记录构成的数据库，其中的每条记录都是不可更改的，并且可以被多个用户共享。

每一个区块都包含一个时间戳和交易数据，这些数据可以是任何内容，例如货币交易，文件存储，合同等等。每一个区块都由一个唯一的数字标识，称为哈希，它可以让我们将当前区块与上一个区块进行对比。每一个新增的区块都会被记录到区块链中，这样就可以建立一个不可篡改的记录序列。

区块链的另一个重要特性是去中心化。它不依赖于任何中央机构，而是由多个用户共同维护。所有的交易都会被记录到区块链上，这样就可以确保所有的交易都是安全可靠的。因此，区块链技术可以被用于创建安全可靠的分布式数据库，用于存储和管理重要信息。

另外，区块链还可以用于智能合约，这是一种自动执行的合同，它可以让双方在无需受信任的情况下安全地进行交易。智能合约可以让双方避免任何第三方的干预，从而更加安全可靠。

总之，区块链技术是一种极具潜力的技术，它可以被用于创建安全可靠的分布式数据库，也可以用于智能合约，从而使双方可以安全可靠地进行交易。区块链技术有可能改变我们的生活，它可以让我们更加安全可靠地进行交易，也可以改善我们的数据管理能力。

『一』Blockchain explained in vernacular

1. It is an open and transparent underlying technology system of digital currency. In addition to the private information of the transaction parties being encrypted, other data is open to everyone, and anyone can query and develop related Qingchang applications. The entire system is highly transparent.

4. This ledger is constantly being generated, calculated and stored.

To put it bluntly, blockchain is the general ledger of transaction records of global Internet users. It’s much simpler to understand this way.

『二』 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 issued the "Blockchain Information Service Management 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".

(2) Extended reading of blockchain vernacular introduction:

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.

『三』 Introduction to blockchain technology What is blockchain technology

1. Blockchain technology is one of the top ten typical judicial technology applications on the Internet.

2. 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.

3. Generally speaking, the blockchain system consists of data layer, network layer, consensus layer, incentive layer, contract layer and application layer.

4. Among them, the data layer encapsulates the underlying data blocks and related data encryption and timestamps and other basic data and basic algorithms; the network layer includes distributed networking mechanisms, data dissemination mechanisms and data The verification mechanism is obvious; the consensus layer mainly encapsulates 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 encapsulates various Class scripts, algorithms and smart contracts are the basis of the programmable features of the blockchain; the application layer encapsulates various application scenarios and cases of the blockchain. In this model, the chain block structure based on timestamps, the consensus mechanism of distributed nodes, economic incentives based on consensus computing power, and flexible programmable smart contracts are the most representative innovations of blockchain technology.

5. The consensus mechanism of the blockchain has the characteristics of "the minority obeys the majority" and "everyone is equal". Among them, "the minority obeys the majority" does not entirely refer to the number of nodes, but also to computing power. , number of shares, or other characteristic quantity that a computer can compare. "Everyone is equal" means that when a node meets the conditions, all nodes have the right to give priority to the consensus result, which will be directly recognized by other nodes and may eventually become the final consensus result. Taking Bitcoin as an example, Caizihe uses proof of work. Only if he controls more than 51% of the accounting nodes in the entire network, is it possible to forge a non-existent record. When there are enough nodes joining the blockchain, this is basically impossible, thus eliminating the possibility of fraud.

『四』What exactly 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. Simply put, blockchain is a decentralized distributed ledger database.

Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms. After reading this, you may still be confused. In fact, in vernacular terms, blockchain is a decentralized distributed ledger database. The advantage of this distributed ledger is that buyers and sellers can trade directly without any intermediary. Everyone has a backup, even if your copy is lost, it will not be affected.

So what is distribution and decentralization? Take marriage registration as an example. The past twoWhen an individual gets married, he or she must go to the Civil Affairs Bureau to go through the formalities, and then enter the information into a computer to complete the legal process. What if we use blockchain technology? As long as two people agree to get married and post a message in their circle of friends, the marriage process is completed and there is no need to go to the Civil Affairs Bureau. Your friends are common witnesses. They may be scattered around the world, but their mobile phones will help you record the information and tell others who want to know the situation.

If you want to conceal your marriage information, you used to have to modify the records on the Civil Affairs Bureau's computer, but now you have to modify the records on the mobile phones of all insiders at the same time. The more people who know about it, the less likely it is to modify it. Therefore it is an impossible task. This is distribution and decentralization.

On the network, every once in a while, a block will be generated. This block is equivalent to a network record book, which is used to record relevant information that has occurred over a period of time. Waiting for this record book When the record is full, a new record book will be generated. Once the information is recorded, all participants will be notified and everyone's record book will be updated simultaneously.

These record books are eventually connected in series with each other. This is blockchain technology. Because of the use of cryptography technology, if someone wants to unilaterally tamper with the message, it will be verified through the blockchain algorithm protection mechanism. If the time point does not match and the related information does not match, other people will not update their record books. Then this information is invalid.

Therefore, compared with traditional information storage technology, blockchain technology is more secure, transparent, and information is irreversible.

Blockchain is not equal to Bitcoin, it is just an underlying technology invented to realize the digital currency of Bitcoin. Blockchain can be applied in a wider range. In addition to digital currency, it can also be applied in financial aspects such as P2P lending, global payment, micro-finance, electronic payment, remittance, etc. It can also be used in people's livelihood aspects such as intellectual property, elections, and notarization. The prospects for future development are huge.

『Wu』How to explain blockchain in a popular way

“Blockchain technology is considered to be the next generation of disruptive core technology after steam engines, electricity, and the Internet. If we talk about steam engines It has released people's productivity, electricity has solved people's basic living needs, and the Internet has completely changed the way information is transmitted. As a machine that builds trust, blockchain will likely completely change the way value is transmitted in the entire human society."

I have just come into contact with the blockchain. There are too many basic knowledge that need to be understood and known. Don’t worry, today I will popularize this knowledge for you. Today, let’s first take a look at what public chains, private chains, alliance chains, and side chains are.

『Lu』What does blockchain mean?

『淒』What is the concept of blockchain? What is blockchain? Is it a scam?The most complete explanation of blockchain

What is the concept of blockchain?

On October 25, 2019, the country advocated the development of blockchain. Overnight, the blockchain concept became popular.

However, many people are hearing about blockchain for the first time.

So, what is blockchain?

Let’s take a look at it from an academic perspective:

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 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 transactions. Information, used to verify the validity of its information (anti-counterfeiting) and generate the next block.

In fact, blockchain is essentially a decentralized database.

Is blockchain the same as Bitcoin? Blockchain is not Bitcoin. The first application of blockchain is Bitcoin.

What are the characteristics of blockchain? Now let’s take a look at several characteristics of the blockchain:

1. Decentralization:

The most important feature of the blockchain is decentralization, and the blockchain system is different Based on a centralized database, it is not controlled by any person or entity. Through distributed storage, data is completely copied and distributed on multiple computers, and each node realizes information self-verification, transmission and management.

2. Non-tamperability:

The blockchain system also has the characteristics of non-tamperability. In the blockchain system, each node is the center and no information can be changed, not even the administrator can modify this information. The consensus mechanism of the blockchain has the characteristics of "the minority obeys the majority" and "everyone is equal". Only when more than 51% of the accounting nodes in the entire network are controlled, it is possible to forge a non-existent record. This situation is basically impossible, thus eliminating the possibility of fraud.

3. Publicity:

In a blockchain system, all nodes in the network can easily access information. The foundation of blockchain technology is open source. In addition to private information being encrypted, blockchain data is open to everyone. Anyone can query blockchain data and develop related applications through public interfaces, so the entire system information is highly transparent. .

4. Independence:

Because the blockchain is decentralized, it can facilitate peer-to-peer transactions, so there is no need for a third party whether in transaction or exchange of funds. of approval.

Based on consensus specifications and protocols, the entire blockchain systemThe system does not rely on other third parties, and all nodes can automatically and securely verify and exchange data within the system without any human intervention.

Let’s assume an environment: 6 people live in dormitory 188 of the university

There is a ledger in the dormitory for Xiao Li, who is good at calculation, to keep accounts.

In the beginning, when the dormitory sold paper boxes or bought some public items, Xiao Li would record them in the ledger. If Xiao Li wanted to enrich himself and made false accounts, there would be less money in the account books, but no one would know.

After all, there is already a general ledger room, who would have nothing to do to keep track of the ledgers?

However, one day, because Xiao Li took more, there were obvious errors in the account book. Now, he could no longer hide it, so Xiao Li had to admit his mistake and make up the money.

So, how to solve this problem?

If blockchain is used to solve the problem:

Everyone in the dormitory takes out a ledger, and every time a transaction occurs, everyone records it in their own ledger. , such problems will not arise, because everyone is keeping accounts and can see the transaction records and final results on the ledger.

Xiao Li can’t change, you can’t change, and neither can your lower bunk. No one can change it.

This is because the previous accounting model was a centralized accounting model, and the current accounting model is a decentralized accounting model, where everyone is the center and everyone is the accountant.

If someone wants to change it, it will obviously be ineffective if they only change the data on their own account book, unless they bribe three people.

So, is blockchain a scam?

With the emergence of the great benefits of blockchain, in a short period of time, the prices of blockchain-related assets have soared, and ordinary investors are becoming more and more interested in blockchain. And criminals have also taken aim at this. There are some criminals who wear the gorgeous cloak of "blockchain" and use the blockchain to commit fraud or issue digital currencies without permission, leading many people to think that the blockchain is a scam.

But in fact, it is not. Blockchain is just a technology. If it can be used well, it will benefit the public and promote the development of the industry.

In particular, the application of blockchain is very wide and can be applied to almost everything of value to human beings.

Medical field: For example, when you go to the hospital for medical treatment, you can directly check the previous medical treatment in your own database, which greatly saves medical resources and saves medical expenses for repeated examinations.

Food traceability: Do you know where the food on your table comes from? Which logistics team is transporting it? By using blockchain it can be trackedinformation. It can provide us with a single source of truth.

Supply chain application: For example, when we buy a product on a certain product, it leaves the factory, goes to the distributor for logistics turnover, goes to the seller's store warehouse, and then reaches the consumer's hands. During these processes, if something goes wrong, only you will know about it, and others, especially consumers, will not.

Well, this is where I introduce you to the relevant knowledge about the concept of blockchain. I hope it can be helpful to you.

『8』 A simple and easy-to-understand introduction to what is blockchain

Blockchain is an important concept of Bitcoin and is essentially a decentralized database. , and as the underlying technology of Bitcoin. The blockchain is a series of data blocks generated using cryptographic methods. Each data block contains information about a Bitcoin network transaction and is used to verify the validity of its 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 distributed cryptographically to ensure that it cannot be tampered with or forged. Account book. 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 automated scripts to A new distributed infrastructure and computing paradigm that uses smart contracts composed of code to program and manipulate data.
European crowdfunding and Ethereum both utilize blockchain technology.
