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.

The above example is a centralized system because 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. You just need to know that blockchain relies on these technical points to ensure data security and is not easilytamper. 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 failed nodes and malicious nodesThe number of points is limited, so it will not cause abnormal consistency in the 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 also 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" What is a blockchain?" I was stunned for a moment, how could this idiot care about such an avant-garde word? I pretended to be calm and prepared to talk about the technical principles bit by bit, but I could see the confused expression of that idiot through the screen of my mobile phone. How to explain "what is blockchain" to people who have a little bit of Internet concepts and technical foundation? This seems to be a very thorny problem??

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

The core essence of blockchain is "decentralization", and almost all operating modes of blockchain operate around the concept of "decentralization". Once you understand what "decentralization" is, you can basically explain the question "what is a blockchain?" For Erga, of course, he must perform a version that he can understand.

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

"Are there still many villagers who take credit now? By the end of the year, some of the accounts cannot be remembered clearly, and there are still many defaulters or those who refuse to accept their accounts?" At this point, Ergazi got emotional and kept complaining. Nowadays, people's hearts are not as old as before, and business is difficult to do!

"Before youThe operation mode of the canteen is a typical centralized one. You grant credit to the villagers and you can take credit. All accounting is directly connected with our villagers through you. You are the center of all accounting. " 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, and he is very shrewd 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 picture of numbers and English. String, and each account has a timestamp to record the time of occurrence, which cannot be relied on. "

Gazi had another question: "Is it possible that the people who owe the debt have a good relationship with the villagers, and they join forces to tamper with the accounting? Then you won’t be able to explain clearly at that time??”

“Gazi, that’s all you have, 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. Everyone has a degree of closeness and distance between them, and it is impossible for everyone to favor the same person. If it were a computer, more than half of the computers on the entire network would need to recalculate. This project would be so huge that it would be 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 the characteristics of being difficult to tamper with.

Ergazi was silent for a moment, seeming to be digesting the example I just gave him. I don’t know how much he can understand the example. Not long after, he sent me a voice message on WeChat: "Does the blockchain mean that I used to learn from the Internet?"All purchases and payments have to go through Jack Ma’s house. If there is a blockchain, can we directly trade with the seller? Anyway, the accounting is very safe. "

"Okay, Gazi, it's really clear at first glance. Blockchain is essentially a decentralized distributed ledger data cloud. Of course, it can be understood according to your understanding. "I'm very happy that Ga Zi can roughly appreciate the true charm of the blockchain. Fortunately, my words have not been in vain.

What is Bitcoin? (Picture quoted from the Internet)

"Then Bitcoin What is this thing again? What does it have to do with blockchain? "Gazi asked.

I thought about it briefly and decided to continue to explain to Gazi with the story of the canteen: "In your canteen, the villagers can't keep accounts for you for free all day long. Do you have to carry some during the holidays? 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 has to be a rule, right? "Gazi asked very puzzled.

I explained: "Zhang San went to your store to borrow a pack of cigarettes on credit, but Li Si knew about it first and helped you keep an account first, and then other people knew about it. Keep accounts, then Li Si will be able to get a small red flower as a reward ~ This small 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 small red flower??"< p>“Can Bitcoin be spent as money? 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 a credit guarantee from the state, so they have value. Bitcoin is the value formed by consensus among Bitcoin network users, and it has tradable properties, so it can be used to carry value. "What is said here is a bit profound. I don't know if Gazi 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? ”

If you don’t go to the Three Treasures Hall for nothing, you will beA typical example of this. Despite a large circle, both blockchain and Bitcoin, in fact, the question he really cares about is "Is investment in blockchain projects 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!

Up to now, there are only three situations in investing in blockchain: mining, currency speculation, and 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 is to obtain returns by purchasing mining equipment such as mining machines, mining virtual currencies, and then selling them for cash. . 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 something only a very small number of investors who understand technology can do well, and my childhood friend Gazi obviously can’t do 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, they are very different. Ordinary investors cannot determine the value of a virtual currency itself. 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 unstandardized, and fraud and hacker attacks often occur. 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 disagree with me and come to "speculate in coins"!

The "September Fourth Movement" stipulated that the issuance of virtual currency is illegal

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 inflammatory rhetoric, and then create the illusion of profitability by building a software and hardware ecosystem of issuing new coins + mining + currency speculation, and then finally run away. Our country's laws clearly stipulate that the issuance of virtual currencies is illegal.

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

And how to identify some pyramid schemes under the guise of blockchain? 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 have no actual products to circulate, and rely more on developing "downline" to ensure top-level profits. With the rise of the concept of blockchain, this MLM model has shown an intensification trend, and it even deceives people under the banner of state support for new technologies.

When Gazi asked, “Can blockchain projects be invested in?”, I realized the seriousness of the problem. Gazi is a typical young man from a small town, and his pursuit is his wife and children. But when faced with the attraction of "wealth", people often do inappropriate things. Mining and currency speculation are simply not suitable for him, let alone blockchain investment projects that are most likely "illegal financing" or "illegal pyramid schemes"!

I quickly dialed Gazi’s phone number and conducted the above analysis carefully??

❺ What are the main application areas of big data in the future

Big data not only means massive, diverse, and fast data processing; A disruptive way of thinking, an intelligent infrastructure, and an innovative technological change.
Big data not only means massive, diverse, Internet of Things, and wisdomCities, augmented reality (AR) and virtual reality (VR), blockchain technology, speech recognition, artificial intelligence, and digital convergence are the seven development directions for the future application of big data.
Trend 1: Internet of Things
Internet of Things: Connect all items to the Internet through information sensing devices to exchange information, that is, things are related to each other to achieve intelligent identification and management.
The Internet of Things is an important part of the new generation of information technology and an important development stage in the "information age".
The core and foundation of the Internet of Things is still the Internet, which is an extension and expansion of the network based on the Internet;
The client extends and expands to exchange information and communicate between any items. That is to say, things are related to each other.
Trend 2: Smart City
Smart city is the use of information and communication technology to sense, analyze, and integrate key information of the core system of urban operation; to include people’s livelihood, environmental protection, public safety, urban services, Respond intelligently to various needs, including industrial and commercial activities. Its essence is to use advanced information technology to realize smart urban management and operation, thereby creating a better life for people in the city and promoting the harmonious and sustainable growth of the city. The success or failure of this trend depends on the amount of data and whether the data is sufficient, which depends on the cooperation between government departments and private enterprises; in addition, the developing 5G network is a standard used worldwide, and if the product is adopted by a smart city, it will be applicable in smart cities around the world.
Trend 3: Augmented Reality (AR) and Virtual Reality (VR)
Virtual reality technology is a computer simulation system that can create and experience a virtual world. It uses computers to generate a simulated environment; it is a A system simulation of multi-source information fusion, interactive three-dimensional dynamic vision and entity behavior immerses users in the environment. These two technologies have recently begun to reduce prices and improve quality, moving towards the mass market. VR applications were mainly focused on video games at the beginning, but now the application goes beyond video games and can be used for teaching. Using VR equipment, you can complete the wiring of home plugs and wires, just like a plumber technician teaching.
Trend 4: Blockchain Technology
Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. 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 technology refers to a way for all people to participate in accounting. There is a database behind all systems. You can think of the database as a big ledger. Blockchain has many different applications, and almost all technology companies in the United States are trying to apply it. The most common application is the transaction of Bitcoin and other cryptocurrencies.
Trend Five: Speech Recognition Technology
It is expected that in the next 10 years, speech recognition technology will enter various fields such as industry, home appliances, communications, automotive electronics, medical care, home services, and consumer electronics. Many experts agreeSpeech recognition technology is one of the ten important technological development technologies in the field of information technology from 2000 to 2010. The fields involved in speech recognition technology include: signal processing, pattern recognition, probability theory and information theory, vocalization mechanism and hearing mechanism, artificial intelligence, etc. A great advantage of this industry is that companies developing technology intend to commercialize this technology. Speech recognition technologies from Google, Amazon and Apple can be licensed and used on hardware services of other companies.
Trend 6: Artificial Intelligence (AI)
Artificial Intelligence (Artificial Intelligence), the English abbreviation is AI. It is a new technical science that studies and develops theories, methods, technologies and application systems for simulating, extending and expanding human intelligence.
Artificial intelligence needs to be educated and fed with a lot of information to evolve, which can produce some unexpected results. AI has a great impact on the media industry, for example. Now computers and robots can write very good articles, and can produce hundreds of articles an hour at a low cost.
AI will have a drastic impact on economic development, and many knowledge industries and white-collar jobs may also be replaced by robots. But he has a very positive attitude towards AI, which will make life better. For example, self-driving cars are definitely safer than human driving.
Trend 7: Digital Convergence
Since around 1995, people have been discussing the so-called "digital convergence". In different usage scenarios, we will still need very different digital devices - light There are many options depending on the screen size, sound effects, and cameras, all of which require different packages.
So digital is more like "iCloud", which means that all devices will access the same remote database, so that your digital life can be completely synchronized and you can seamlessly switch usage scenarios at any time.
But in addition to the convergence of "vehicles", what we should be more concerned about is another digital convergence, a convergence of Internet business models, or to be more clear, the digital convergence is the convergence of "content" and "e-commerce" Confluence.

❻ Why more and more people choose to invest in the Speaker voice chain

To be honest, this is a good project that will brighten people’s eyes
In the implementation of blockchain technology Among application projects, Speaker voice chain has highlights that are different from other projects. It complies with national policies and does not engage in the magic of ICO to attract money. The powerful technical team designed a user-friendly mobile client APP, allowing users to read aloud with one click on their mobile phone, and receive token incentives while paying for voice labor. The more you read, the more authentic digital currency SPK you will gain. It is a vertical application of blockchain technology in voice big data collection, with the purpose of serving the emerging artificial intelligence AI - no hot spots, just real business. It aims to collect massive voice data in multiple languages ​​and dialects around the world, forming a data value foundation and standing proudly among the emerging star projects of the blockchain. it strives to build community, a highly consistent consensus has been formed. It is building an application ecosystem based on Tsinghua University's accelerator X-elerator, with unlimited prospects. In short, it is a truly good project that bridges application scenarios and draws a clear line with Aircoin. Where can I find such a good project?
