① 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.

② What is the origin of blockchain

Blockchain originated from Bitcoin. On November 1, 2008, a person claiming to be Satoshi Nakamoto published The article "Bitcoin: A Peer-to-Peer Electronic Cash System" explains the architectural concept of an electronic cash system based on P2P network technology, encryption technology, timestamp technology, blockchain technology, etc., which marks the birth of Bitcoin.

Two months later, the theory came into practice, and on January 3, 2009, the first genesis block with serial number 0 was born. A few days later, block number 1 appeared on January 9, 2009, and was connected to the genesis block number 0 to form a chain, marking the birth of the blockchain.

In recent years, the world's attitude towards Bitcoin has been ups and downs, but blockchain technology, one of the underlying technologies of Bitcoin, has received increasing attention. Formed in BitcoinIn the process, blocks are storage units one by one, recording all communication information of each block node within a certain period of time.

The links between each block are realized through random hashing (also called hash algorithm). The latter block contains the hash value of the previous block. With the expansion of information exchange, a block Continuing with one block, the result is called a blockchain.

Characteristics of the blockchain:

1. Decentralization change. 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.

2. 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.

3. 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.

4. Security. As long as you cannot control 51% of all data nodes, you cannot manipulate and modify network data at will. This makes the blockchain itself relatively safe and avoids subjective and artificial data changes.

5. 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.

④ What exactly is the blockchain

From the perspective of its application, the blockchain concept is a distributed shared ledger and database with the characteristics of decentralization, The files cannot be tampered with, leave traces throughout the process, can be traced, are collectively maintained, and are open and transparent. Blockchain originated from Bitcoin, and the first blockchain was born on January 9, 2009.

Definition of blockchain

Blockchain can currently be divided into public blockchain, joint blockchain and private blockchain. Public blockchain means that any individual or group can send transactions, and the transactions can be effectively confirmed by the blockchain, and anyone can participate in its publicity process. As the name suggests, joint and private blockchains refer to a combination of multiple individuals or groups, and an individual or a company has exclusive write access to the blockchain. Basic difficulties

⑤ What is blockchain? A popular explanation of a new accounting method (you will understand after reading it carefully)

In the past two years, there has been a The new financial model is "blockchain". I think many people still don't understand the meaning of this. After all, "blockchain" is still "advanced" to ordinary people, so blockchain What is the popular explanation? In fact, it is not as complicated as we imagined, so let me tell you what "blockchain" is and see what is special about this model!

The most popular explanation of blockchain:

What exactly is the "blockchain" that people often talk about? I believe that many people don’t know much about it, and most of the information they view on the Internet is “unclear”. In fact, it is easy to understand. So what is the popular explanation of blockchain? Fundamentally speaking, this model is a "decentralized" accounting method. So what is "decentralization"? All our current exchanges and communications on the Internet will actually be stored in a "centralized" server on a browser or APP. The other party can check our browsing information at will, and "decentralization" is convenient. This can be completely avoided.

Once information is written into the "blockchain", it cannot be tampered with, ensuring its authenticity and confidentiality. It can also avoid third-party platforms in transactions on the virtual market. Intervention, the transaction is directly completed by both parties, which saves a lot of procedures and time, and also ensures that the information is not leakedThere will be no security issues such as exposure and transparency, and there will be no possibility of data loss!

After reading the above introduction, do you have a new understanding of the "blockchain" model? can't read? Let’s take a look at it through a comic below!

Fields of application of blockchain

The "blockchain" model can be applied in many fields, the first of which must be finance. The earliest blockchain is from Born in Bitcoin. This new technology can also be used in education, e-commerce, film and television, etc. Now all walks of life are exploring this new field, hoping to have a foothold in the development of the future era!

⑥ What is blockchain technology? What exactly is blockchain?

Blockchain technology is one of the top ten typical judicial technology applications on the Internet. 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. In fact, it is a decentralized database. Blockchain, as the underlying technology of Bitcoin, is a series of data blocks generated using cryptographic methods. Each data block contains a batch of Bitcoin network transaction information, which is used to verify the validity of its information (anti-counterfeiting) and generate the next data block.

Blockchain originated from Bitcoin. On November 1, 2008, a person who called himself Satoshi Nakamoto published the article "Bitcoin: A Peer-to-Peer Electronic Cash System", which elaborated on P2P network technology, encryption technology, timestamp technology, and block technology. The concept of electronic cash system framework such as chain technology marks the birth of Bitcoin.

(6) The birth of the blockchain toilet Extended reading:

The birth of the blockchain:

The concept of blockchain was first proposed by Satoshi Nakamoto in 2008. In the following years, blockchain became the core component of the electronic currency Bitcoin: a public account for all transactions. By using peer-to-peer networks and distributed timestamp servers, blockchain databases can be autonomously managed.

The blockchain invented for Bitcoin made it the first digital currency to solve the problem of repeated consumption. Bitcoin design has become a source of inspiration for other applications. On December 20, 2016, the Digital Currency Alliance-China FinTech Digital Currency Alliance and FinTech Research Institute were officially established.

⑦ What is blockchain and how was it born? What are the types of blockchain?

If you want to understand blockchain, you must first understand the basic structure of the program. Everything we see on the Internet is constructed through computer language. There are many kinds of computer languages, but the most basic characters that make up the language are codes, and blockchain technology is a way of applying codes, which is different from traditional centralization. The difference is that the blockThe chain has the characteristics of immutability, privacy, security, and consensus.

There are many application scenarios for blockchain. The most successful case so far is Bitcoin, followed by electronic invoices, cross-border payments, etc. Based on the interoperability of data, it is impossible to With characteristics such as tampering, it can also be used to save some important data. As long as this data uses blockchain technology as the underlying technology, it can never be destroyed and will be saved forever. No person or institution has the ability to modify or delete it. In addition, there are certain intersections between blockchain payment and education, medical care, credit reporting, automobiles, transportation and other fields. It is a technology, not a certain product, so there is only one type of it, but with the application As the scene changes, its role is also different. It can be integrated with existing scenes in almost any field and then derive other applications.

⑧ What is blockchain and how to make money with blockchain

Blockchain is a new application of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. model. The so-called consensus mechanism is a mathematical algorithm that establishes trust and obtains rights and interests between different nodes in the blockchain system.

How to make money in the blockchain:

1. Earn commissions through promotion.

The blockchain approach is to first register an exchange account, generate your own invitation link, and then promote it. If someone registers the exchange through your link and generates transactions, you will get a commission.

2. Coin speculation.

Speculating in currencies is like speculating in stocks. Coin speculation is a way to make money on the Blockchain with the lowest threshold.

3. Mining.

"Mining" in Bitcoin is the accounting process. This process requires grabbing, and if you grab the opportunity to bookkeeping rights, you will be rewarded, and the reward is Bitcoin. This behavior is "mining".

4. Develop wallet.

The wallet is the infrastructure of the blockchain, just like the "Alipay Zheng Xinque" or "WeChat Pay" of the blockchain.

Extended information:

1. Blockchain is an important concept of Bitcoin. It is essentially a decentralized database and serves as the bottom layer of Bitcoin. technology. 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. piece.

2. Blockchain was born from Satoshi Nakamoto’s Bitcoin. Since 2009, various Bitcoin-like digital currencies have appeared, all based on public blockchains.

3. On January 20, 2016, the Digital Currency Seminar of the People’s Bank of China announced that it had achieved phased results in digital currency research. The meeting affirmed the value of digital currency in reducing the issuance of traditional currency and stated that the central bank is exploring the issuance of digital currency. The expression of the People’s Bank of China’s Digital Currency Seminar has greatly enhanced the digital currency industryconfidence. This is the first time that the five central bank ministries and commissions have expressed a clear attitude towards digital currencies since they issued a notice on preventing Bitcoin risks on December 5, 2013.

⑨ What exactly is blockchain and how do ordinary people make money in blockchain?

Blockchain is so popular that it makes people eat melons The crowd was caught off guard. Nowadays, no one knows about blockchain, but many people do not have a clear understanding of the definition of blockchain.

So, what exactly is blockchain?

Regarding blockchain and Bitcoin, most people have this misunderstanding: Bitcoin is blockchain.

In fact, Bitcoin and blockchain are not the same thing. Blockchain is the underlying technology of Bitcoin, but the first usage scenario after the birth of blockchain is Bitcoin.

I will explain to you what Bitcoin is and what blockchain is. Please move your bench quickly!

What is Bitcoin?

Bitcoin is a digital currency, a peer-to-peer encrypted digital currency. It is not a tangible paper currency such as RMB or US dollars. It is generated by computers through specific mathematical calculations. Also stored in the computer.

Because Bitcoin is just a string of data in a computer, it is also called a "virtual currency" compared to paper currency. To put it simply, you can understand that Bitcoin is just a string of numbers with cash value, similar to Q coins. In other words, Bitcoin has no actual value. Its current value is supported by the faith of currency speculators. If the faith is gone, the value of Bitcoin will collapse.

Bitcoin is magical, what is its magic?

If you want to get Bitcoin, in addition to buying it, you can also mine it. The original Bitcoin is mined!

1) Mining

The first thing that comes to mind for many people is the image of a coal mine:

Mine, absenteeism, dust , black coal, large trucks.

Bitcoin mines are not like this. They only need electricity, network cables, and computers. However, mining this mine is a technical job, and it tests the performance of the computer's CPU and GPU.

2) Transaction

How does a Bitcoin transaction proceed?

Each user has a unique address, which is the Bitcoin "wallet". For every transaction, for example: A pays B a Bitcoin, a Weibo post will be posted publicly in the system saying: "I gave B a Bitcoin @B". These records will be kept as evidence at every terminal of the system. on the chain.

If A wants to go back on his word, andTo tamper with Bitcoin’s transaction history, every terminal record on the network must be modified. However, this is not easy, because only A whose computing power exceeds the sum of the computing power of all nodes in the system can tamper with transaction records. Obviously, this is unrealistic.

In the transaction process, Bitcoin uses a decentralized accounting method, which is also blockchain technology. Simply put, blockchain is a decentralized distributed ledger database.

What is blockchain?

The blockchain was created along with Bitcoin. During the formation of Bitcoin, blocks were storage units one by one, recording the communication information of each block node. Blocks are very similar to For database records, every time data is written, a block is created. With the expansion of information exchange, one block continues with another, and the result is called a blockchain.

Blockchain is a distributed ledger technology. Everyone participates in accounting, and everyone has a copy of the ledger information. This account book is not easy to forge and is traceable.

For example:

On a certain day of a certain year, Lao Wang lent Xiao Wang 10,000 yuan. Lao Wang told everyone around him the news , the transfer records were posted on WeChat Moments, and everyone helped them testify to the existence of this transaction.

Lao Wang and Xiao Wang are two nodes. These two nodes generate transaction time, location, person and other information, and they are packaged to form a "block". Lao Wang’s friends are also nodes. These nodes jointly record the transaction status and details (blocks) of the two nodes Lao Wang and Xiao Wang. These blocks are connected to form a chain, forming a decentralized database.

In the past, only both parties knew when Lao Wang and Xiao Wang borrowed money. This was the centralized accounting model. But now everyone knows it and records it in their own ledgers. This is the decentralized accounting model. model.

When one day, Xiao Wang regrets that he did not borrow the money, everyone around him will know their transaction information, so Xiao Wang will not be able to deny it. This is the blockchain Information sharing cannot be tampered with.

How do ordinary people make money by participating in the blockchain?

I have summarized several methods suitable for ordinary people to make money during the blockchain bonus period.

1. Direct investment in blockchain: buy coins or buy some blockchain stocks, but the currency circle is risky, so you must be cautious when buying, and there are many blockchain stocks now. However, there are risks in the stock market, so investment needs to be cautious.

2. Make blockchain self-media: run a WeChat public account or Toutiao account, write articles about blockchain and publish them on it. If you are good, you can also get some good profits.

3. Participate in technology development: In fact, it is very simple, it is to participate in the process of blockchain development. However, this method requires high technical threshold.

4. Blockchain training: Companies that can provide blockchain technology training or knowledge training.

That’s all the relevant knowledge about what blockchain is, I hope it can bring you some help.
