『一』What does blockchain mean? One article will teach you how to understand blockchain

According to Xinhuanet: On the afternoon of October 24, 2019, the Political Bureau of the Central Committee of the Communist Party of China The Bureau conducted the 18th collective study on the development status and trends of blockchain technology.

When organizing this study, Xi Jinping said: "The integrated application of blockchain technology plays an important role in new technological innovation and industrial transformation. We must use blockchain as a core technology An important breakthrough for independent innovation, clarify the main direction, increase investment, focus on conquering a number of key core technologies, and accelerate the development of blockchain technology and industrial innovation."

"Blockchain" for a time This word has become popular all over the Internet. People with a software development background may have a certain understanding of blockchain technology, but most of us are ordinary people. As ordinary people, when faced with the term "blockchain", it is full of questions. Questions, what does blockchain mean, what does distributed ledger represent, and what is the difference between centralization and decentralization?

The Internet defines blockchain as: Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Blockchain is an important concept of Bitcoin. It is essentially a decentralized database. As the underlying technology of Bitcoin, it is a series of data blocks generated using cryptographic methods. Each The data block contains information about a batch of Bitcoin network transactions and is used to verify the validity of the information (anti-counterfeiting) and generate the next block.

Simply speaking, blockchain is a decentralized database.

This is the function of distributed accounting. Distributed accounting brings benefits and convenience to our lives.

In real life, "blockchain" technology can be widely used in medical care, travel consumption, financial payment and other fields in the future. It will bring convenience to people’s lives, and at the same time, it will also comprehensively improve our financial environment and medical environment.

『二』 What is blockchain in simple terms

Blockchain is a term in the field of information technology. Essentially, it is a shared database. The data or information stored in it has the characteristics of "unforgeability", "whole process traceability", "traceability", "openness and transparency" and "collective maintenance". 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". Blockchain has entered the public eye and become the focus of society. From a technological perspective, blockchain involves many technological issues such as mathematics, cryptography, the Internet, and computer programming.
Extended information:
From an application perspective, in short, blockchain is aA distributed shared ledger and database with the characteristics of decentralization, non-tampering, full traceability, traceability, collective maintenance, and openness and transparency. These characteristics ensure the "honesty" and "transparency" of the blockchain and lay the foundation for establishing trust in the blockchain. The rich application scenarios of blockchain are basically based on the fact that blockchain can solve the problem of information asymmetry and achieve cooperation, trust and coordinated action among multiple entities.
Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism and encryption algorithm. Blockchain is an important concept of Bitcoin. Essentially, it is a decentralized database. At the same time, as the underlying technology of Bitcoin, it is a series of data blocks associated with cryptographic 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 data block [8]. In fact, the word blockchain does not appear in the original English Bitcoin white paper, but blockchain. In the Chinese translation of the earliest Bitcoin white paper [9], blockchain was translated into blockchain language. This is the earliest time when the Chinese word "blockchain" appeared.

『三』 How is the development of the blockchain market

Blockchain definition

According to the China Academy of Information and Communications Technology’s “Blockchain White Paper (2019)” Definition in "Blockchain": Blockchain is an accounting technology that is jointly maintained by multiple parties, uses cryptography to ensure transmission and access security, and can achieve consistent data storage, difficulty in tampering, and prevention of repudiation; in the People's Bank of China's "Financial "Distributed Ledger Technology Security Specification" defines: Distributed ledger technology is a distributed infrastructure and computing paradigm formed by the highly integrated integration of multiple core technology systems such as cryptographic algorithms, consensus mechanisms, point-to-point communication protocols, and distributed storage.

Blockchain technology collectively maintains trusted database technology in a decentralized manner. It has the characteristics of decentralization, tamper-proof, and high scalability. It is working closely with big data, cloud computing, artificial intelligence, 5G, etc. The new generation of information technology is rapidly integrated and applied to various important fields such as government affairs, medical care, charity, and judicial governance. It is expected to promote mankind from the information Internet era to the value Internet era.

Blockchain development stages

In the past ten years, blockchain technology has been continuously upgraded. The industry divides its evolution and development into three stages. These three stages are not realized sequentially. It is a process of common development and mutual promotion.

The blockchain industry will be further standardized in 2020

In 2020, my country's blockchain policies will continue to be favorable, standards and regulations will be more perfect, industry scale will continue to grow, technology will continue to innovate and develop, and application demonstration effects in key areas will accelerate. At the same time, based on the problems existing in the development of my country's blockchain in 2019, CCID Blockchain Research Institute proposed to speed up the top-level design and formulation, establish a sound supervision system, accelerate core technology innovation research and development, and promoteSix suggestions include third-party evaluation and certification, strengthening professional talent training, and accelerating the implementation of applications in various fields.

——The above data comes from the "China Blockchain Industry Market Foresight and Investment Strategic Planning Analysis Report" by the Qianzhan Industry Research Institute.

『四』 What is the concept of blockchain? What exactly is blockchain? Read it in three minutes!

On October 25, 2019, Xinwen Broadcast sent a very important signal: the country must vigorously develop blockchain. After that, blockchain has become an Internet celebrity, and the figure of "blockchain" is floating in the streets and alleys. In fact, many technology companies have already deployed blockchain technology.

Although blockchain is very popular, many people do not know much about blockchain.

What is blockchain?

Let’s first take a look at how Du Niang explained it. Network display: Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms.

Why is blockchain called blockchain?

The blockchain is linked by blocks one by one, and the blocks are storage units that record the communication information of each block node. The blocks are much like the records of a database. Each block is a storage unit. Writing data every time creates a block. With the expansion of information exchange, one block continues with another, and the result is called a blockchain.

What are the characteristics of blockchain?

Blockchain mainly has the following characteristics:

1. Decentralization: In the blockchain system, every node has equal rights. and obligations, there is no central control here. Decentralization has well established trust relationships with each other. Although there is no central management organization, people can collaborate with each other and trust each other. This mainly applies blockchain distributed ledger technology.

2. Openness: Blockchain data is open to everyone. Except for some encrypted information that is not open, everyone can check the data here.

3. Independence: 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 any human intervention.

4. Security: Blockchain has a certain degree of security and cannot be tampered with. Because everyone in the blockchain system has the same ledger, if someone wants to tamper with it, it is possible to forge a non-existent record only if they control more than 51% of the accounting nodes. Of course, this is basically impossible. This is mainly due to the core technology of the blockchain: the consensus mechanism. The consensus mechanism has the characteristics of "the minority obeys the majority" and "everyone is equal".

5. Anonymity: Many people feelIf the blockchain is so open and transparent, does that mean we have no privacy? In fact, no, although the transaction information in the blockchain is open and transparent, the identity information of the account is encrypted and can only be accessed with authorization.

Now let me tell you a story to help you better understand the blockchain.

There are three people in the family, mom, dad, older brother and younger brother. Last year, my father was in charge of the family's account books. He was responsible for all the family's income and expenses alone.

However, on the day of Double Eleven, my mother, who has always been frugal, wanted to buy herself a beautiful piece of clothing on a certain online store. When she checked the account book, she found something was wrong. It stands to reason that except for some money deposited in banks and financial management, the whereabouts of the daily consumption money at home are all in this account book, but no matter how you look at it, it is wrong. Some consumption is clearly not recorded, but is recorded.

Later, my father took the initiative to confess that he couldn’t help but buy a pack of cigarettes.

Later, my mother changed her strategy and the whole family kept accounts. Everyone recorded their monthly consumption expenditure in their own account books. Whenever there was a transaction or consumption at home, my mother would shout, "Book it," and everyone would record the transaction in their own books. This is the decentralized accounting model, where everyone is the center and everyone has a ledger.

The previous accounting model for dad was centralized accounting. If dad wanted to do something alone, it would be difficult for anyone to see it. The decentralized accounting model has solved the problem of centralization very well. The disadvantage of bookkeeping is that it is very difficult for dad to tamper with the books.

For example, if my father wants to take some money from the ledger and secretly buy cigarettes, the amount of money is limited, and if he wants to take the money, he has to change the ledger, but he only tampered with his own ledger. No, he had to change the accounts of three people including himself. And this is undoubtedly more difficult than reaching the sky.

So, many times my father had the idea of ​​smoking, but he had no choice but to give up the idea due to the current situation.

Are blockchain and Bitcoin the same thing?

In fact, blockchain and Bitcoin are not the same thing. It is just the underlying technology of Bitcoin. Bitcoin is the first digital currency applied by blockchain.

In 2008, Satoshi Nakamoto first proposed the concept of blockchain. In the following years, it became a core component of the electronic currency Bitcoin, serving as a public account book for all transactions. Blockchain was first applied to Bitcoin.

The origin of blockchain is to solve the problem of trust, and one of the most successful applications of blockchain is digital currency. Bitcoin is arguably the most successful application of blockchain so far.

What are the applications of blockchain?

The application of blockchain is actually very wide. In addition to digital currency, the future applications of Bitcoin are still very extensive. Blockchain technology has been widely used in different industries. Such as product traceability, copyright protection and transactions, payment and settlement, Internet of Things, digital marketing, medical care, etc., promoting different industries to quickly enter the "blockchain+" era.

1. Payment and clearing: Blockchain can abandon the role of transit banks, realize point-to-point payment, reduce transit fees, and accelerate fund utilization.

2. Product traceability: For example, if we buy a piece of clothing on a certain store, we can see the past and present life of this piece of clothing.

3. Securities trading: Traditional securities trading requires the coordination of four major institutions, which is inefficient and costly. Blockchain technology can independently complete one-stop services.

4. Supply chain: Introducing blockchain technology into the supply chain system, synchronizing information within the system can control all links, better complete division of labor and collaboration, and facilitate subsequent accountability.

5. Intellectual property rights: With copyright on the chain, our photographic works, musical works, literary works, etc. will become our information, and the ownership of the information will be confirmed and become our property.

『五』What is the development trend of blockchain in 2019?

As an industry insider, what I see is that the big waves wash away the sand, the survival of the fittest, those who are unreliable and pure deception Blockchain projects die faster in the cold winter. Even if they don’t die, they will slip away. Companies that are truly capable and earnestly research blockchain technology will have a higher probability of surviving and then take off in the next bull market.
In terms of currency prices, the overall price in 2019 should still be in a bull market, because bears are long and bulls are short.
There will be more breakthroughs and developments in technology and business applications in 2019.

『Lu』 What will happen to the blockchain in 2019

Updated accounting technology”

『撒』 What is blockchain

Blockchain is a term in the field of information technology. Technically speaking, 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".

On January 10, 2019, the National Internet Information Reform Office issued the "Blockchain Information Service Management Regulations". On December 2, 2019, the word was selected into the top ten buzzwords of 2019 by "Yi Wen Qi Zi".

『8』 What is blockchain

What is blockchain? What changes will it bring to your future life?

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

Blockchain is an important concept of Bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of Bitcoin, it is a series of cryptographic methods related to each other. Each data block generated contains a batch of Bitcoin network transaction information, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block.

In fact, the original English version of the Bitcoin white paper does not appear in the word blockchain, but uses chain of blocks. In the earliest Chinese translation of the Bitcoin white paper, chain of blocks was translated into blockchain. This is the earliest time when the Chinese word "blockchain" appeared.

The Cyberspace Administration of China issued the "Blockchain Information Service Management Regulations" on January 10, 2019, which will come into effect on February 15, 2019.

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-transformable. Fake distributed ledger.

So in conclusion, this is undoubtedly a new technology that changes life. In the future, the production activities of the entire society will be carried out with blockchain as the underlying logic. Many things We all have it at our fingertips, and with the integration of artificial intelligence and big data, we can easily handle things that may seem cumbersome now, such as some securities market transactions and intelligent matching of financial management activities.

To put it simply, blockchain is a network computing center that integrates people, property, machines, and goods, and packages them into a whole; putting it on an infrastructure to run.
