1. What is the meaning of blockchain

Blockchain is a shared database. Blockchain is distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc. New application models of computer technology.

Blockchain does not belong to any industry. Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. In a narrow sense, blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and is a cryptographically guaranteed distributed ledger that cannot be tampered with or forged.

Features

Decentralization. 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.

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.

2. Explain blockchain in vernacular

Recently, various ICO financial scams have been blocked in China, but this does not hinder the vigorous development of blockchain technology. After all, technology is innocent and can bring benefits to people. As for how to use it, it depends on people to operate it. If the operation is good, you can recommend development. If the operation is not good, it is like the major ICO projects. Find some knowledge for Internet celebrities to conduct so-called illegal fund-raising and financial fraud.

After talking for a long time, what is blockchain? When it comes to blockchain, the first thing that comes to mind for many people is Bitcoin. We need to solve a problem. Bitcoin is a blockchain, but blockchain is not Bitcoin. Simply put, blockchain is distributed ledger technology (DLT), not a token. It has many characteristics, such as decentralization, traceability, and difficulty in tampering.

(1) Blockchain is a distributed database

First of all, this is a decentralized distributed architecture system. Therefore, having only one central server or node is not called a blockchain. For example, if you go to Taobao to buy a mobile phone, you and the seller are strangers and have no basis for trust. If you give the money to the seller first, the seller may block you by not delivering the goods, and then your mobile phone money will be gone. If the seller ships first, do you pay? It is possible that you do not pay the seller after receiving the goods, and one party may lose money anyway. At this time, a third-party guarantee is needed to solve the trust problem. Just like Alipay now, you give money to Alipay and the seller will deliver the goods. When you receive the goods, the seller will receive the money.

UpThe example above is a centralized system, as all guarantee work is handled by Bora, a third-party payment company. Suppose one day Alipay wants to tamper with data, neither buyers nor sellers can do anything because all authority is in the hands of one company.

At this time, a distributed database is needed. This third party is no longer Alipay, but thousands of monitors. When you buy a mobile phone on Taobao, you will shout to everyone that I am going to XXX to buy a mobile phone, and I paid XXX yuan. The other person will yell like everyone else. I collected XXX’s mobile phone bill and sent it over. In this way, everyone knows about this transaction and everyone is recording this transaction, so it is useless if one or two nodes have problems or malicious behavior, because most nodes have recorded this matter.

(B) Blockchain uses encryption technology to ensure data security

There are two important points here: 1. Crypto-enabled hash function 2. Asymmetric encryption.

If you are interested in specific concepts, you can go online, but people without basic knowledge may not be able to understand it, because these two points are too professional. In fact, if you only know the use of blockchain, you don’t need to have an in-depth understanding of it. It is also a technical concept. All you need to know is that blockchain relies on these technical points to ensure data security and is not easily tampered with. Of course, many people say that these two points can guarantee 100% non-tampering. I want to be a little conservative here. As an author who works in the security industry, I have always been skeptical about 100% security, so it may be more appropriate to call it difficult to be tampered with.

I will briefly introduce these two concepts and try to explain them clearly in plain English.

1. Cryptographic Hash Function

This is mainly used to verify the integrity of information. For example, I sent a message to the company leader saying that I was sick on Friday and needed to take a day off. At this time, a hash value will be generated based on the message I sent, such as: 123456. At this point, when the leader receives this message, a hash value is also generated. Because the content of the message I sent has not changed (it has not been tampered with), the hash value remains unchanged, still: 123456. This is if someone wants to tamper with this news and get sick on Friday and need to take a year off. At this time, the hash value will change, such as: 123489. That's when we learned our information had been tampered with.

2. Asymmetric encryption

It is mainly used for information encryption and authentication. It is actually two keys, one is called the public key and the other is called the private key. Public key encryption, private key decryption.

A public key is a key that everyone has. You own it, I own it. We can all encrypt with this key, but when decrypting it must be decrypted with my private key. If you don't have my private key, you can't decrypt it.

(C) The blockchain uses a consensus algorithm to reach consensus on new data.

The role of the consensus algorithm is to enable all nodes to reach a consensus on the new block. In other words, everyone must approve the new block.

For a centralized deployment system, this is simple, everything is controlled by the center, but in the distributed system of the blockchain, it is very complicated.For example, there are three nodes. A said he bought a mobile phone from XXX store and paid for it, B said he didn’t pay, and C said he didn’t pay enough. Then who do you listen to? What's more, blockchain technology is not as simple as three nodes, but a huge distributed system.

This is when a solution is needed. There is a corresponding problem in computer science called the "Byzantine Universal Problem" or "Byzantine Fault Tolerance" (BFT). This question was raised not because of Bitcoin, but because of a special background.

Early aircraft had three independent control systems. Why do we need three independent control systems? For example, in an emergency, there is a plane opposite. How to judge whether you should hide? If there is only one system, there is no choice, which is equivalent to centralized deployment. If the system breaks, you're dead. What if one of the two systems breaks? The good ones are said to hide, and the bad ones are said not to hide. The computer cannot judge the final result. Therefore, three independent systems are needed to support it, and the probability of two total failures is still very small. But this only takes into account injuries. What should I do if there is a malicious system? Is three enough? The answer is no, we need four systems to maintain consensus.

The use of blockchain is similar, because it is supported by a huge number of nodes, and each node is an independent system without interfering with each other. We can assume that the number of failed nodes and malicious nodes is limited, so it will not cause abnormal consistency of data.

Related questions and answers: What is blockchain? What is the use?

Blockchain is a new computing paradigm and distributed infrastructure that uses fast chain data structures, distributed node consensus algorithms, cryptography and smart contracts based on automated script code to produce, verify, store and transmit data. It can also be said that blockchain is a distributed ledger technology that can provide a decentralized trust mechanism in a non-trust environment, allowing multi-party participants to conduct secure and trust-based transactions without intermediaries.

The core advantage of blockchain technology is decentralization. It can realize decentralized credit-based transactions in a distributed system where nodes do not need to trust each other by using data encryption, timestamps, distributed consensus and economic incentives. Point-to-point transactions, coordination and collaboration provide solutions to the common problems of high cost, low efficiency and insecure data storage in centralized institutions.

The fields of use of blockchain include digital currency, certificates, finance, anti-counterfeiting and traceability, privacy protection, supply chain, entertainment, etc. With the popularity of blockchain and Bitcoin, many related top domain names have been registered. It has had a relatively large impact on the domain name industry.

Related Q&A: Can you explain to me what a blockchain is in an easy-to-understand way?

Er Gazi is my friend since we were young, and we were naked in Hegou together. Later, I came to the city to study and work, and lived a life as a drifter in the north; he farmed at home and did some small business, and now he has a son and a daughter, and his life is safe. He envied my so-called "seen the world", and I envied his simple life without the pressure of mortgage loans. We have completely different and mutually enviable lives??

That day, Ga Zi came to me on WeChat and asked "District" Blockchain isWhat? "I was stunned for a moment. How could this idiot care about such avant-garde words? I pretended to be calm and prepared to talk about the technical principles bit by bit, but I could see that idiot's clouds and fog through the phone screen. Confused expression. How to explain clearly "what is blockchain" to people with a little bit of Internet concept and technical foundation? This seems to be a very thorny problem??

The village kiosk interprets the core of blockchain (picture quoted from the Internet )

The core essence of blockchain is "decentralization". Almost all operating modes of blockchain operate around the concept of "decentralization". Once you understand what "decentralization" is, then This can basically explain the question "What is blockchain". For Erga, of course, he must interpret a version that he can understand.

"I said, Gazi, you still open the canteen at the east end of the village? Are you here? "Gazi answered yes. I decided to use this canteen as an example to explain the actual use scenarios of blockchain in modern business and financial models, so that he can better understand what blockchain is.

"Now then Are there many villagers who take credit? By the end of the year, are some of the accounts unclear and there are still many defaulters or those who refuse to acknowledge their accounts? " At this point, Ergazi got emotional and kept complaining that people are not as old as they used to be and business is hard to do!

"In the past, the operation mode of your canteen was a typical centralized one. You gave credit to the villagers and all the accounting was done. They are all directly connected to our villagers through you, and you are the center of all accounts. " Ergazi said he understood and let me continue.

I said: "If you fail one day, then all the debts will become dead debts? It is estimated that it will be difficult to get back the IOUs written in black and white. Forget about remembering those accounts orally, but the decentralization of the blockchain can solve this problem very well. As long as the earth still exists, then the blockchain will remember that every account will exist forever." Erga became more energetic after hearing this.

The essence of the blockchain is "decentralization"

"The The essence is decentralization. Once someone takes credit from you, all the neighbors in the village will help you keep accounts. Because there are many nodes for accounting, it is neither easy to make mistakes nor others can refuse to pay, so everyone reaches a consensus. If someone maliciously fails to repay the debt, the whole village will know his character, and no one will be willing to have financial dealings with him in the future??"

At this point, Gazi was obviously a little excited. It seemed that he was I was really worried about the credit issue. Seeing that Gazi was interested, I also felt a small sense of accomplishment and continued: "Of course, the above is just an analogy. In fact, the blockchain does not really allow villagers to get paper. The pen helps you keep accounts, but it is done through the Internet and computer networking. "

At this time, Gazi was a little confused and asked: "Then what others bought from me, wouldn't everyone in the village know it? Then who would buy things from me? There is really no privacy at all. And you don’t have time to keep accounts here. Last year’s accounts are said to be this year’s. What if you keep procrastinating? "

"Okay, Gazi, your question is on point. "It seems that Gazi is not stupid at all. He is still very smart in doing business.. I continued to explain: "So, the recording and transmission of this information are all done through encryption. What you see is a string of numbers and English, and each account has a timestamp to record the time it occurred. , can't be relied on."

Gazi had another question: "Could it be that the people who owe the debt have a good relationship with the villagers, and they join forces to tamper with the accounting? Then it will be unclear what to say? ?”

“Gazi, that’s all you have to be careful about, haha.” I understood Gazi’s concerns and continued to explain: “The mechanism of the blockchain requires more than 51% of people to agree to tamper with a bill. Yes. There is a degree of closeness and distance between people, and it is impossible for everyone to prefer one person. If it were a computer, more than half of the computers in the entire network would need to recalculate. This project is so huge that it is almost impossible to complete?? ”

In this way, through the actual situation of the canteen and combined with some scenes in life, Gazi understood what is in the blockchain: decentralization, distributed accounting, consensus mechanism, encryption mechanism, timestamp, and Characteristics that are not easily tampered with.

Ergazi was silent for a moment, as if he was digesting the example I just gave him, and I don’t know how much he can understand it. Not long after, he sent me another voice message on WeChat: "What does blockchain mean? In the past, when I bought goods online and paid for them, I had to go through Jack Ma's house. If there is a blockchain, can it be done directly?" When trading with sellers, bookkeeping is very safe anyway."

"Okay, Gazi, it's really clear. Blockchain is essentially a decentralized distributed ledger data cloud. Of course, it can be understood as you understand it. "." I am very happy that Ga Zi can roughly appreciate the true charm of blockchain. Fortunately, my words have not been in vain.

What is Bitcoin? (Picture quoted from the Internet)

"Then what is Bitcoin? What does it have to do with the blockchain?" Gazi asked.

I thought about it briefly and decided to continue explaining the story of the canteen to Gazi: "In your canteen, the villagers can't keep accounts for you for free all day long. Do you have to bring something to visit during the holidays? Yes, this is the reward mechanism of the blockchain, and everyone who participates in bookkeeping may receive rewards."

"Then what are the rewards based on? There must be a rule, right?" Gazi asked very puzzled.

I explained: "Zhang San went to your store to buy a pack of cigarettes on credit, but Li Si knew about it first and kept an account for you first. Then other people knew about it and started keeping accounts. Then Li Si could get A small red flower as a reward ~ This little red flower is generated by the blockchain system and has no value in itself, so you do not need to pay any cost for this little red flower??"

"Then Bitcoin can be used as money Flowers? How is it different from the banknotes we usually spend?" Gazi continued to ask.

"Bitcoin is a digital encrypted virtual currency. In principle, it has no value itself like our banknotes. However, banknotes have the country as a credit guarantee, so they have value. Bitcoin is the Bitcoin network The value formed due to consensus among users and has tradableAttributes can therefore be used to carry value. "What is said here is a bit profound. I don't know if I can understand it.

I continued to explain: "Banknotes can be printed infinitely. If more are printed, inflation will occur. When we were young, popsicles worth 1 cent were very good. , now you can’t eat with 1 yuan. Of course, there are many factors that affect inflation. The number of Bitcoins is fixed, and there is no possibility of unlimited over-issuance. However, different people have different judgments on their value, and coupled with the influence of supply and demand and investor sentiment, their prices are always fluctuating. ”

What is the difference between Bitcoin price fluctuations and stocks?

“So is speculating in Bitcoin just like speculating in stocks? Can you understand it this way? "Gazi seems to know a lot.

"In fact, there are some similarities, but there are also big differences. "I continued Gazi's topic: "The price of stocks always fluctuates around the valuation of companies, and there is government supervision in the stock market. Bitcoin itself has no value. It is priced entirely based on supply and demand and player valuations. It grows wildly without any government supervision. Therefore, it may have higher risks and higher returns than stocks. "

In the end, Gazi revealed the real purpose of today. He asked me: "Can I invest in blockchain projects? ”

Gazi is a typical example of those who don’t go to the Three Treasures Hall for anything. Although there is a large circle of people who are involved in both blockchain and Bitcoin, in fact, what he really cares about is “blockchain project investment” Is it reliable? "When these words came out, I was extremely shocked. Now the so-called blockchain investment projects have actually reached fourth- and sixth-tier cities and small towns!

As of now, there are only three types of blockchain investments. Situation: Mining, currency speculation, so-called blockchain projects.

Mining and currency speculation are still the main lines of the blockchain (pictures quoted from the Internet)

The so-called mining means mining by purchasing mining machines, etc. Equipment, mine virtual currency, and then sell it for cash to get returns. You can install the mining machine yourself, or you can find a mining pool to host it, but the core keys to profitability are "computing power" and "power consumption" as well as Investment in equipment. With the sharp drop in the price of virtual currencies and the increase in mining difficulty, the current mining returns of many currencies are very unsatisfactory. Mining is obviously only a very small number of investors who understand technology can play successfully. I My childhood friend Gazi obviously can’t play with it.

As for “coin speculation”, I have just introduced some differences between Bitcoin and stocks in the previous section. In principle, although they are both “buy low and sell high” operations , but there is a huge difference. Ordinary investors cannot determine the value of a virtual currency itself, and the price is determined entirely by the relationship between supply and demand, which is somewhat similar to what we often call "market makers." On the other hand, the virtual currency trading market is extremely Irregularities, theft and hacker attacks often occur, and the risk factor is much greater than investing in stocks. For the safety of my friends' funds, I am one of the ten thousand people who disagrees with "coin speculation"!

"September 4th" It is illegal to issue virtual currencies

In fact, in my opinion, most of the so-called investment projects in the market are essentially ""Illegal fund-raising" and "pyramid schemes". Some so-called blockchain investment projects attract investors into the circle through various packaging and instigative rhetoric, and then form a profitable ecosystem by building a software and hardware ecosystem of issuing new coins + mining + currency speculation. The illusion, and then finally ran away. Our country's laws clearly stipulate that the issuance of virtual currencies is illegal.

Illegal pyramid schemes now wear the cloak of blockchain (pictures quoted from the Internet)

And some are disguised as blockchain How to identify MLM activities under the guise? In fact, these pyramid schemes are also so-called Ponzi schemes, what we people often call "empty gloves." These so-called "direct sales" or "marketing" activities often do not have any actual products to circulate. , more relying on the development of "offline" to ensure top-level profits. With the rise of the blockchain concept, this pyramid scheme has shown an intensification trend, and even deceives people under the banner of state support for new technologies.< p>When Gazi asked the question "Can blockchain projects be invested?" "When I saw "Wealth", I realized the seriousness of the problem. Gazi is a typical young man in a small town, and his pursuit is his wife and children. But when faced with the attraction of "wealth", people often do extraordinary things. What? Mining and currency speculation are not suitable for him at all, let alone some blockchain investment projects that are most likely to be "illegal financing" or "illegal pyramid schemes"!

I quickly called Gazi and said my sincere words Conducted the above analysis??

Canaan Technology’s net income in the second quarter was 178 million yuan, an increase of 1.6 times from the previous quarter

On August 31, Beijing time, Canaan Technology ("Canaan Inc." or the "Company") announced the consolidated financial data for the second quarter of 2020 (the "current quarter") (the same below). The company's total net income for the quarter reached RMB 178.1 million, an increase of 160% from the previous quarter..9%. This was mainly due to the 198.5% increase in the total amount of computing power sold in the quarter (total computing power sold = ∑ number of mining machines sold × design computing power value of each mining machine), as well as the number of mining machines sold An increase of 153.5%. At the same time, the company's profitability has also improved, with the company's gross profit increasing from RMB 2.4 million in the first quarter of 2020 to RMB 43.3 million in the second quarter, a quarter-on-quarter increase of 1,711.5%.
