(5) Blockchain from a researcher’s perspective from entry to mastery Extended reading

General Secretary Xi Jinping at the Political Bureau of the CPC Central CommitteeDuring the 18th collective study session, it was emphasized to “use blockchain as an important breakthrough for independent innovation of core technologies” and “accelerate the development of blockchain technology and industrial innovation.”

The forward-looking judgment of the Party Central Committee has brought "blockchain" into the public eye and has become a common concern for financial capital, the real economy and social public opinion.

From network power to big data, from media integration to blockchain, the Political Bureau of the CPC Central Committee has collectively studied and aimed at the forefront of technological change, demonstrating the direction, forward-looking judgment and future foresight of the Party Central Committee, leading It follows the pace of China's industrial reform and economic transformation. This collective study by the Political Bureau of the Central Committee specifically emphasized "blockchain", which opened up imagination space for the development and application of blockchain.

From a technological perspective, blockchain involves many scientific and technical issues such as mathematics, cryptography, Internet and computer programming. From an application perspective, simply put, blockchain is a distributed shared ledger and database, which has the characteristics of decentralization, non-tampering, full traceability, traceability, collective maintenance, openness and transparency.

These characteristics ensure the "honesty" and "transparency" of the blockchain and lay the foundation for the blockchain to create trust. The rich application scenarios of blockchain are basically based on the ability of blockchain to solve the problem of information asymmetry and achieve collaborative trust and consistent action among multiple subjects.

㈥ How to develop a block into a blockchain What is a blockchain

1. The development of a block into a blockchain requires the software Go. Go is an open source programming language that makes it easy to build simple, reliable, and efficient software.

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", created a reliable "cooperation" mechanism, and has broad application prospects.

㈦ The most straightforward explanation of blockchain

Blockchain is a technology that can ensure that the data on the chain cannot be tampered with or forged.

Blockchain has five important technical characteristics: decentralization, non-tamperable information, openness and transparency, collective maintenance and reliable database.

Detailed explanation of blockchain:

1. Detailed explanation of the definition of blockchain

In a narrow sense, blockchain is a way to block data in chronological order. A chained data structure composed of sequential connections, and a cryptographically guaranteed distributed ledger that cannot be tampered with or forged.

Broadly speaking, blockchain is a distributed infrastructure and computing method. It is a security technology used to ensure data transmission and access.

In summary, in summary, the blockchain is equivalent to a disintermediated database, consisting of a series of data blocks. Each of its data blocks contains information about a Bitcoin network transaction, which is used to verify the validity of the information and generate the next block.

2. Blockchain infrastructure

Blockchain consists of six infrastructures: data layer, network layer, consensus layer, incentive layer, contract layer and application layer.

3. Purpose of blockchain

Blockchain is mainly used to solve trust and security issues in transactions.

4. Applications of blockchain in different fields

From a scientific and technological perspective, blockchain involves many scientific and technical issues such as mathematics, cryptography, Internet and computer programming; from an application perspective From a perspective, blockchain is a distributed shared ledger and database, which is decentralized, cannot be tampered with, leaves traces throughout the process, can be traced, collectively maintained, and is open and transparent.

5. Issues that need attention in blockchain

As an important breakthrough for independent innovation of core technology, the security risk of blockchain is a major shortcoming, and security incidents occur frequently. A wake-up call for the industry. To embrace blockchain, we need to accelerate the exploration and establishment of a security system that adapts to the blockchain technology mechanism.

㈧ After reading this article, you will have a thorough understanding of the blockchain

In this article, all the content I introduced is based on the blockchain in today’s world. The fact that the blockchain field has already happened is not some imagination or opinions about the blockchain. I think that as long as you read this article carefully, you will easily have a basic and accurate understanding of blockchain.

The main content of understanding blockchain in just ten minutes is divided into four sections. 21 topics and 4 sections are:

The first national blockchain strategy.

Second, Bitcoin and its literal representation involve four topics.

Third, blockchain and its technical logic involve 13 topics.

Fourth, blockchain empowers the economy and society, involving three topics.

Let’s first look at the first part of the blockchain national strategy. The first part of the blockchain country. Everyone knows that we humans have experienced six times.information revolution. Seven or eight years ago, the first information revolution created primitive language, social tacit understanding, and the second information revolution saw the emergence of writing. The third information revolution in feudal society invented papermaking and printing, and the fourth information revolution in the late 19th century invented radio.

In the fifth information revolution of the 20th century, television appeared again, and now in the sixth information revolution, computers and the Internet have appeared. The emergence of computers and the Internet has given rise to the rapid development of various new technologies. Especially in 2020, the digital economy has experienced epoch-making development.

Why do you say that? The characteristics of high bandwidth, low latency and large connections in the 5G era have enabled the implementation of the four major technologies of ABCD.

What are the four major ABCD technologies

The a here refers to Artificial Intelligence, which is artificial intelligence technology.

B refers to Blockchain, blockchain technology.

C refers to cloud computing cloud computing technology

D refers to big data technology.

The word blockchain is now completely popular all over the country. On October 25, 2019, the Political Bureau of the Central Committee of the Communist Party of China announced the development of blockchain technology. The current situation has been collectively studied, so the requirement of this meeting is to use blockchain technology as the core technology.

As an important breakthrough for independent innovation, it is necessary to accelerate the innovative development of blockchain technology and industry. On April 20, 2020, the National Development and Reform Commission officially included blockchain into new infrastructure. Blockchain, why do you think it is so awesome? Let us say that blockchain is not an extension of the Internet, it is a subversion of the Internet. In the future, many, many technologies will grow on this blockchain and realize blockchainization.

So, how can we accurately learn and understand the blockchain?

We found that among the four major technologies of ABCD, only the block is naturally built-in It's financial. Therefore, we must learn and understand blockchain from the IT perspective and the financial perspective, and even learn and understand blockchain from the level of national governance. If you only study and understand blockchain from an IT perspective, it is impossible to understand the huge influence and influence of this technology. Then, your understanding of this will be biased. Even more, you may disapprove of blockchain technology. In addition, in the process of learning blockchain, you should also pay attention toIt has a lot of new terms, which requires concentration and understanding step by step.

Let’s first understand blockchain from a financial perspective.

Bitcoin and its birth performance

To understand the blockchain, it involves Bitcoin, and what about the birth of Bitcoin? , and it is inseparable from the evolution of currency. We know that currency is a special commodity that is separated from commodities and serves as a fixed general equivalent. In fact, we humans have used a lot of currencies, including physical currency, weighing currency, paper money, accounting currency, etc. As for accounting currency, it includes electronic currency and digital currency. Electronic currency itself is not a currency. It is just used to represent the same amount of currency. It is a token.

Then the total amount of his tokens will not increase due to the increase of electronic currency. Alipay, WeChat, payment, and online banking are typical electronic currencies. As for digital currency, it is itself a legal currency. The total amount of this fiat currency will increase with the increase of digital currencies. We know that when it comes to physical currency, we humans have actually chosen many things as general equivalents.

Weighing currencies are some heavy metals. Later, people chose gold among the heavy metals. Why choose gold? Because gold has the characteristics of rarity, divisibility, and the most stable chemical properties. What needs to be noted here is gold. It is not issued by any country. It is provided by nature. of. Your country's total amount is as much as nature provides. Therefore, the country does not need to provide credit guarantees for the value of gold.

However, as for gold, it has some flaws in its use, and it is difficult to carry when you go out again, so there are descendants. Paper money appeared in the Northern Song Dynasty. At that time, paper money was not currency in the current sense. The currency at that time was still gold, but we used paper money to represent gold. We called it the gold standard. The gold standard is the gold standard, which is a monetary system with gold as the standard currency. The core essence of the gold standard is that how much currency a country issues should be decided based on how much gold your country has. It does not mean you can issue as much currency as you want.

At that time, the Great Depression of the United States reached January 10, 1934. On this day, the newly elected President of the United States made a very important decision to abandon the gold standard and issue $3 billion. Think about it, abandoning the gold standard, in theory, means that he can issue as much currency as he wants. Even if there is no gold in the treasury, he can issue banknotes as long as he wants to. Then someone will ask, do you issue suchDuowei, will it be possible to exchange for gold of equal value by then?

Look at the paper currency at this time, it has been separated from gold, and national credit has appeared. This, we call it national credit. Credit is the collateral currency. Now, when mainstream countries issue currency, they also issue it with national credit as a guarantee.

What are the benefits? The advantage is that it can regulate the economy. When the economy is not doing well, a little more hair can drive economic development. The increase or decrease in this variable will cause a chain reaction of the entire economic aggregate. This is the multiplier effect in economics. Once a country masters this thing, some countries will be fascinated by it. But if it is not well controlled, it will lead to national credit bankruptcy. As a result, many people began to reflect. This reflection is, when issuing currency, is it better to use national credit as a guarantee, or is it better to stick to the gold standard based on the total amount of gold. This question involves the birth of Bitcoin

㈨ Blockchain and Bitcoin, are there any good channels for novices to recommend from getting started to becoming proficient?

Blockchain digital currency entry channels for novices There are many, and there are many websites on the Internet that provide learning, communication and investment, such as Babbitt Forum, Dr. Bi Forum, Bihu, etc. However, I see that you want to make money but are afraid of losing money, so I advise you not to play. If you don’t have the responsibility, Don’t be mentally prepared to lose money. It’s better to live a normal life.
