区块链的英文是什么,区块链的英文是什么意思

A. What is the concept of blockchain?

The English name of blockchain is Blockchain. Translated into Chinese, it is a literal translation, just like the Internet. Blockchain is actually an underlying protocol. Roughly speaking, it has several components:

The first is called distributed ledger; the second is called decentralized trust; the third is called asymmetric encryption; The fourth is called timestamp; the fifth is called smart contract. These five underlying technologies are all a bit mysterious to talk about, but everyone seems to understand them.

For example, why Alipay is so powerful is because it solves a trust problem in online shopping.

The buyer does not give the money to the seller first, but gives it to Alipay first. Then you verify that the goods are received and the money is OK, and then it is transferred to the seller's account. Alipay plays the role of an intermediary.

Of course, Alipay was not invented by Jack Ma. One of the earliest founders of PayPal was also Elon Musk. This was his first pot of gold, using the Internet to solve centralized trust.

B. Zihang talks about currency: Newbies in the currency circle don’t even know what “blockchain” is

First of all, I believe that before everyone learns about blockchain, You’ve heard of Bitcoin first, right? Because we all know that the first people to hold Bitcoin made money!

But one point of view is wrong: What point of view? Many people believe that Bitcoin is the blockchain. In fact, Bitcoin is just a type of blockchain asset, and it is the earliest blockchain asset. The concept of blockchain comes from Bitcoin. The reason why Bitcoin can be so arrogant and exist independently without relying on any organizational structure is because the bottom layer is supported by blockchain technology.

Just like our mobile phones can run, the bottom layer is supported by Android or ios system. So what kind of technology is blockchain? Why is it so powerful? Can make Bitcoin so valuable! The English name of blockchain is block chain, and block means block. You can imagine that if you fall or bump into something, you may have bruises, right? The blocks in the blockchain contain some The data block of transaction information, something, may have a bruise, right? The block in the blockchain contains some data blocks of transaction information, and the chain in the blockchain connects the data blocks. , this is like a big ledger. Anyone who uses this blockchain ledger can directly query any transaction information arranged in order, and it is difficult to tamper with. So how does it do it?

Let’s give a simple example based on local materials: There are now a total of 100 readers, who are linked through the Internet to form a blockchain network system. Please pay attention! We are not reading this article now, but a blockchain network system. I'm in this system,Ask one of the people, for example, this person's name is panda, to borrow 10 yuan, and then panda transfers 10 yuan to me in the network system. Then my account or wallet increased by 10 yuan. As for panda, who lent money to Bibi, his account lost 10 yuan. After this transaction is completed, other people in our blockchain network system, after seeing it, will take a small notebook and record the matter. My account will increase by 10 yuan, and panda's account will decrease by 10 yuan.

That’s not right, then what are you doing when you are full and have nothing to do? Why should we record these small and medium-sized "bad things"? This is because the network system will pay wages to those who participate in recording. As long as she records it once, the system will automatically reward tokens that are common in this network system. As long as there is money, everyone is willing to do anything. In reality, there are actually countless individuals in a blockchain system. In other words, our group not only has only 13 people, but they don’t know each other yet, but they can all spread to each other on the system chain and record them in the blockchain in order. For this transaction in the network, if one day I want to default on the debt and no longer plan to pay back 10 yuan to panda, then I must convince more than 51% of the people in the blockchain network system to delete this record or tamper.

If it were replaced by real-world computing power, it would be almost impossible and would require huge costs. This is the characteristic of blockchain technology - decentralized collaboration, transaction data is difficult to tamper with, and transaction information is transparent and queryable. Its main function is to solve two problems that are difficult to solve on the Internet - one is trust and the other is value transfer.

The so-called trust, according to the above scenario, is that I may default on the loan and take the money and run away; the value transfer is: my borrowing account should increase by 10 yuan, while the panda account becomes -10 Yuan money exchange. Then we may have questions again, isn't Alipay and WeChat payment solved now? Wouldn’t it be enough to just confirm the account and transfer the money directly and send a red envelope? Yes, Alibaba and Tencent exist based on solving these two problems. but! Thinking about it from another perspective, if a mere blockchain technology can solve these two problems now, can huge and complex institutions like Alibaba and Tencent be abandoned?

Rebuilding a new network system to apply it to more fields is on the way.

Because, the final conclusion is: this technology builds the value of Bitcoin, then this technical logic can also be used in many other fields. Maybe one day you will be happy to discover - Huh? I am now using a product from a certain blockchain technology company! ? Just like many years ago, one day you unknowingly used QQ and started to learn to watch videos and play games online. Having said that, what does it mean that Bitcoin is an early asset of the blockchain? Why does it add value? According to the scenario mentioned above, the so-called generationTokens are tokens issued by the system to everyone in the group by participating in accounting. These tokens are blockchain assets. (The behavior of everyone participating in bookkeeping is commonly known as mining.) Bitcoin itself is the value token of the Bitcoin blockchain network system

Then why is it Will it add value? Because its quantity is limited, the number of issuances is determined at one time from the beginning of the establishment of the network system and will never be issued additionally.

So, in the future, the more people participate in accounting in a certain blockchain network, the number of people who get it will gradually decrease, and value-added will become inevitable. This is like Alibaba's early stocks. After the Alipay application is launched, the more people participate in using it, the more it is needed, and Alibaba's stocks will inevitably increase in value.

Of course, there are currently many projects applying blockchain technology, but most of them have not found a landing scenario. However, the more people believe that a project created using blockchain technology will be used in the future. If necessary, the price of the tokens of this project will be pushed up. Therefore, there are far more investment opportunities in blockchain assets than in the ordinary stock market. If you invest in a value project, then it may skyrocket like Bitcoin a few years ago, which skyrocketed from 130,000 per coin to a little over 40,000 now. In other words, you don’t need to consider any investment opportunities in other varieties. A few years ago, if you bought Bitcoin with your eyes closed and then ignored it and just went about your own business, the return on this investment would be 100 times in one year.

Profit! How much is that right? The opportunities in this industry are far more than these. Almost all currencies will have the opportunity to rise or fall sharply, but this range of rise and fall is not like the 10% daily limit in stocks. Blockchain assets disappear from trading around the world 24 hours a day, and It is T+0, and there is no limit on the increase or decrease. The price of any variety is completely affected by the limit on the increase or decrease and the pursuit of funds. Most varieties have experienced an increase of more than 100% throughout the year. High This kind of investment opportunity is also difficult to find in other markets.

The currency circle is like Tai Chi. Only when a person is in a state of tranquility can he feel the opponent's strength and intention in the push hand for the first time. What I felt at the time was that only by clearing myself could I receive information to the maximum extent and quickly, and make correct judgments and responses. The same is true in the currency circle.

C. What does blockchain mean?

Blockchain is an important concept of Bitcoin. It is essentially a decentralized database that simultaneously Zhibu is the underlying technology of Bitcoin. It is a series of data blocks generated by using cryptographic methods. Each data block contains a batch of violent times in the Bitcoin network.Transaction information is used to verify the validity of its information (anti-counterfeiting) and generate the next block.

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

2. 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 renaissance that generations have been striving for. dream.

Puyin Group held a Puyin Blockchain Finance Guiyang Strategy Release Ceremony in Guizhou on December 9, 2016. At the meeting, the blockchain will realize the digital circulation of assets and the blockchain financial transaction model. , and discuss the application of blockchain services and social public industries.

D. What should "blockchain" be translated into professional English?

Answer for you
Block chain
First of all, The main function of blockchain is to store information. Any information that needs to be saved can be written to the blockchain and read from it, so it is a database.

E. What is blockchain

The English translation of blockchain is: block chain, block means block, and chain means chain. So let’s first talk about what a block is.
In the Bitcoin network, Bitcoin transactions are happening every moment, and these transaction information will be broadcast to every node through the Bitcoin network. But if there is no one to handle this transaction information, it will be very messy and impossible to check. Therefore, we need to find a bookkeeper to sort out the transaction information, package and save it, and package it well. The information is synchronized to each node through the network. This encapsulated information is called a block.
For example, I don’t have the habit of keeping accounts, so at the end of each month, I have no idea what I bought this month that caused me to be so poor. My wife showed up at this time, and she asked me to report every amount of money I spent to her. She wrote down my expenses in days, and then it was very clear. By the end of the month, she concluded that I was poor. It's because I earn too little.
What are the benefits of keeping accounts this way?
First, the context is clear and I can trace every expense I make. Correspondingly, in the blockchain, you can even trace the digital currency back to the moment it was mined by the miners. This also lays a theoretical foundation for the digital currency to be free of counterfeit currency.
Second, information disclosure. My wife knows exactly how much money I have and how much I have spent, thus avoiding the possibility of private money. Corresponding to the blockchain, this ensures the fairness of each node. How many coins you have does not change at your request. Everyone has an account.
In the Bitcoin network, it is stipulated that accounting should be done every 10 minutes, that is, a person is selected every 10 minutes (as for how to select this person, please stay tuned) to record these 10 minutes.The transactions that occur within the block are recorded in a certain way as a block, and the block is timestamped, and each block is linked in strict chronological order. In this way, many, many blocks are connected in chronological order to form a chain structure, which is what everyone calls the blockchain.
If each block is regarded as a page of an account book, then the blockchain is an account book.
This account book is not a private account book written by the accountant and confirmed by the master.
It is a public account book kept by each participating node.
No one can tamper with the transaction information in the account books at will, and no one can tamper with personal rights and interests information.
This is the meaning of blockchain!

F. Comic illustration: What is blockchain

Comic illustration: What is blockchain

What is blockchain?
Blockchain, English Blockchain, is essentially a decentralized distributed database. Anyone can become a node of this huge network as long as they set up their own server and connect to the blockchain network.
Since the blockchain is essentially a database, what exactly is stored in it? Let’s take a look at the basic unit of blockchain: Block.
A block is divided into two parts:
1. Block header
The block header stores the header information of the block, including the hash value (PreHash) of the previous block. The hash value of the block body (Hash), the timestamp (TimeStamp), etc.
2. Block body
The block body stores the detailed data (Data) of this block. This data contains several rows of records, which can be transaction information or some other information.
What does the hash value just mentioned mean?
Everyone must have heard of MD5. MD5 is a typical hash algorithm that can convert a string of plaintext of any length into a string of fixed length (128 bits). This string is the hash value.
In our blockchain, a more complex hash algorithm called SHA256 is used. After a series of complex calculations, the latest data information (such as transaction records) will eventually be converted into a 256-bit hash value string through this hash algorithm, which is the Hash in the block header. The format is as follows:

Blocks and Hash have a one-to-one correspondence, and Hash can be regarded as the unique identifier of the block.
How are different blocks related to each other? Rely on Hash and PreHash to associate. The PreHash value of each block is equal to the Hash value of the previous block.
Why do we need to calculate the hash value of the block?
Since the blockchain is a chain structure, it must existThe head node (the first block) and the tail node (the last block) of the chain. Once someone calculates the hash value of the latest data in the blockchain, which is equivalent to packaging the latest transaction records, a new block will be created and connected to the end of the blockchain.
The Hash of the new block header is the hash value just calculated, and the PreHash is equal to the Hash of the previous block. The data in the block body stores the transaction records before packaging, and this part of the data information has become unmodifiable.
This process of calculating Hash values ​​and creating new blocks is called mining.
The server used for massive calculations is called a mining machine.
The workers who operate calculations are called miners.
What is so difficult about calculating hash values? Let’s give the most superficial explanation. The formula for calculating the hash value is as follows:
Hash = SHA-256 (Hash of the last block + basic information of the new block + transaction record information + random number)
Among them, the transaction record information is also a string of hash values, and its calculation involves a data structure Merkle Tree. Interested friends can check the relevant information, we will not introduce it for now.
The key computational difficulty here lies in the generation of random numbers. In order to increase the difficulty of Hash calculation, the wretched inventor of the blockchain requires that the first 72 bits of the Hash result must be 0. This probability is too small.
Since (the Hash of the last block + the basic information of the new block + the transaction record information) is fixed, whether the Hash that meets the requirements can be obtained depends entirely on the value of the random number. Miners must go through massive calculations and repeatedly generate random numbers in an attempt to "get lucky" before they can get the correct Hash and successfully mine.
At the same time, the block header also contains a dynamic difficulty coefficient. When the world's hardware computing power becomes faster and faster, the difficulty coefficient of the blockchain will also increase, making the entire network capable of completing the task every 10 minutes on average. A new block is generated.
Friends, do you understand how difficult mining is? It should be added that different blockchain applications are different in details. The mining rules described here take Bitcoin as an example.
Applications of Blockchain

The concept of Bitcoin (BitCoin) was first proposed by Satoshi Nakamoto in 2008, and then based on this idea, open source software and P2P built on it were designed and released. network. Bitcoin is a P2P form of digital currency. Peer-to-peer transmission means a decentralized payment system.
What is a P2P network?
Traditional currencies are uniformly issued by the central bank, and all personal savings are uniformly managed by banks. This is a typical centralized system.
Bitcoin is deployed on a decentralized network composed of many peer nodes around the world. everyEach node is qualified to record and issue this digital currency.
As for the underlying data storage of Bitcoin, it is based on blockchain technology. Each transaction in Bitcoin corresponds to a row in the block data. A simple diagram is as follows:
Each row of the transaction record contains a timestamp, transaction details, and digital signature.
The table is only for ease of understanding. The actual stored transaction details are anonymous, and only the wallet addresses of the payer and payee are recorded.
As for digital signatures, they can be understood as anti-counterfeiting marks for each single transaction, generated by an asymmetric encryption algorithm.
Next let’s talk about the rewards of Bitcoin miners:
The Bitcoin protocol stipulates that miners who mine new blocks will receive rewards. Starting from 2008, it is 50 Bitcoins, and then halved every 4 years. , currently 12.5 Bitcoin in 2018. The new Bitcoins in circulation are all born in this way. No wonder everyone is so eager to mine Bitcoins!
Advantages and Disadvantages of Blockchain
Advantages of Blockchain:
1. Decentralization
Blockchain does not rely on a central node. The data of the entire system is All peer nodes in the entire network are jointly maintained and can store and verify data. In this way, unless the attacker hacks more than half of the nodes in the entire network, the entire system will not be destroyed.
2. Information cannot be tampered
The data in the block cannot be tampered with. Once the data is tampered with even a little bit, the hash value corresponding to the entire block will change accordingly, and it will no longer be a valid hash value, and the subsequent linked blocks will also be broken.
Disadvantages of blockchain:
1. Excessive consumption of energy
To generate a new block, a large amount of server resources must be used to perform a large number of unnecessary trial calculations, which seriously consumes electricity.
2. Network delay of information
Take Bitcoin as an example. Any transaction data needs to be synchronized to all other nodes. The synchronization process will inevitably be affected by network transmission delay, resulting in a long time consuming.
A few additional points:
1. Part of the content of this comic refers to Ruan Yifeng’s blog post "Blockchain Introductory Tutorial". I would like to thank this great master for his popular science.
2. Due to limited space, the knowledge about Merkle Tree and asymmetric encryption has not been discussed in detail for the time being. Interested friends can check the information for further study.

G. What is blockchain and what is its relationship with Bitcoin

Blockchain in English is Blockchain, which is computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. new application models. The so-called consensus mechanism is a mathematical algorithm that establishes trust and obtains rights and interests between different nodes in the blockchain system. Blockchain is the underlying technology of Bitcoin, which is like a database ledger that records all transaction records. This technology is also known for its safety, convenient features have gradually attracted the attention of the banking and financial industries. It is a very important concept in the blockchain world. Many models, such as ledger maintenance, currency issuance, timestamp design, network maintenance, competition between nodes, etc., all rely on this central idea.

The first application of blockchain was Bitcoin, and many countries have recognized the legal status of Bitcoin. There is no Bitcoin organization or central bank in the world to issue Bitcoin. The credibility it relies on is the algorithm. It relies on testing the algorithm and an account book and fair mechanism to ensure circulation. It develops a currency that everyone recognizes and trusts. A mechanism, that's how it works.

Nowadays, people’s concept of blockchain is still very general, and its applications are not very wide. However, in the next ten years or even decades, when it comes to blockchain, it will definitely be the most high-end technology that affects people of all ages. Everyone knows!

H. Explain clearly what is blockchain in an easy-to-understand manner

The English name for blockchain is Blockchain. Block literally means block, block, and chain means chain, chain. Therefore, together they are translated into blockchain.
1. Use cryptography technology to encrypt and decrypt so that records cannot be tampered with. Common blockchain encryption methods include hash algorithm, RSA algorithm, elliptic curve algorithm, etc.;
2. The huge amount of calculation needs to be supported by a reasonable reward mechanism. Because every transaction must be recorded, Bitcoin’s blockchain has more than 60 gigabytes so far. Every new transaction requires confirmation of the information related to the trading account to ensure that the transaction is valid. The huge amount of calculation requires a computer with powerful computing power to complete.
In order to encourage the participation of powerful computing power, Bitcoin provides two rewards: one is to issue a certain number of Bitcoins to these computers every day; instead, all transfer fees are awarded to these computers. (The technical term for these computers is "mining machines", and the people who hold the mining machines are called "miners".)
Biying China is working hard on asset digitization and launched the digital currency crowdfunding platform Biying China.
