❶ How to make money with blockchain

The meaning of blockchain and the answers to how to make money are as follows:
1. The meaning of blockchain: Blockchain is a After the information is confirmed by multiple parties, it is finally stored in multiple places. It is a tool that can solve credit problems during transactions.
2. How to make money with blockchain:
(1) Provide blockchain technology services. Form a corporate team to specialize in the development and application of blockchain technology, and provide your technical results to companies in need for use, or develop corresponding blockchain technology based on the needs of service recipients. A simple understanding of Jimeng is to be a middleman.
(2) Use blockchain technology to issue coins. This method is that the company acts as an issuer and releases a certain number of virtual coins for others to invest, such as Bitcoin, Litecoin, and Dogecoin. At that time, if you wanted to become an issuer, in addition to having blockchain technology, you also had to apply for a series of filing documents and materials such as business qualification certificates and currency issuance qualification licenses from relevant regulatory authorities. Otherwise, if you don’t have these documents, it would be fraud. . However, successfully preparing these documents will still test the strength and capital of the company. If the funds are not strong enough, it will be difficult to sustain.
(3) Payment for blockchain knowledge. In the early days of the blockchain market, many people did not understand what blockchain was and wanted to participate, which inevitably gave rise to a payment market for blockchain knowledge. Since this year, many public accounts with the theme of blockchain have appeared, and many paid blockchain courses and small investment circles have been born.
(4) Register to receive free candies. Candy is a token that the blockchain project team rewards early users in order to attract more users to join early use and dissemination. Similar to the early "Didi", in order to cultivate a large number of early users, a large number of free taxi tickets were issued to users.

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. 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.

The public key is the 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. to the domain name industryrelatively large impact.

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" 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!

"In the past, the operation model of your canteen was a typical centralized one. You granted credit to the villagers and allowed them to take accounts on credit. All accounting was done directly through you and our villagers. You were the center of all accounting affairs." Ergazi said I understand, let me continue.

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

The essence of blockchain is "decentralization"

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

At this point, Gazi was obviously a little excited. It seemed that he was really worried about the credit issue. Seeing Gazi's interest, I also felt a small sense of accomplishment and continued: "Of course, the above isFor example, in fact, the blockchain does not really require villagers to get paper and pen to help you keep accounts, but 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, timestamps, 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: “What does blockchain mean? In the past, when I bought goods online and paid, I had 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 Gazi 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: "Your canteen, the villagers can't keep accounts for you for free all day long, right? 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 kept an account for you first, and then others knew about it. If you keep accounts, Li Si will get a small red flower as a reward.Li~ This little red flower is generated by the blockchain system and has no value in itself, so you don’t need to pay any cost for this little red flower??"

"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 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 areBig difference. 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 called Gazi and conducted the above analysis carefully??

❸ Blockchain can be defined

March 12, 2018 On the same day, the 2nd All Things Growth Conference, co-sponsored by the Hangzhou Science and Technology Commission, Hangzhou Financial Affairs Office, Xiaoshan District People's Government, and Herangna Hangzhou Daily Newspaper Group, and hosted by the Hangzhou Venture Capital Association and Hangzhou Bank, was held in Hangzhou International Held in the press conference hall of the Expo Center, Babbitt and Bytom founder Chang Chai gave a keynote speech on "The future can be predicted and blockchain can be defined."
The following is the content of the speech:
Good morning everyone, I am very happy to be invited to do such a sharing. The theme I shared is "The future can be predicted and blockchain can be defined."
I used to be a science fiction writer and wrote some science fiction novels in college. At that time, science fiction was still a very niche group and very few people read science fiction novels. Later, I had a post that is now very popular. In 2011, a college student asked on Zhihu: If you have 6,000 yuan for investment and financial management, what advice do you have? The advice I gave him at that time was to buy Bitcoin. . Now look at this one worth 20 millionOf course, this is a sad story, because the subject did not buy Bitcoin in the end. It is also a sad story for me, because many people have not read the novel I wrote, but this suggestion is It is often mentioned by people, and in recent years, people have been sending me private messages asking me which currency to buy. However, I am not an expert in investment and financial management. Our company is engaged in blockchain.
Babit established the website in 2011 and established the company in 2014, so we may be the first batch of blockchain companies in China. On what basis do we judge that blockchain technology may be popularized or survive in the future?
This would like to mention a science fiction novel I once wrote in college called "The Art of Slaying Dragons". This computer-themed novel was written in 2007. It tells the story of hackers who can use huge amounts of computing resources on the Internet in the cloud era to complete some very grand scientific computing projects. After this novel was published at the time, it was criticized by many readers. They think this novel seems unreal and doubt that hackers' abilities are beyond ordinary people's imagination.
But now it seems that this novel is not an exaggeration at all. Why? Because in the cloud era, the abilities between people will be disproportionately amplified. In reality, the abilities between people may be a kind of The normal distribution is just like a person's height and weight, but on the Internet, people's ability and influence will be disproportionately amplified. It is a combination of the Matthew effect + the long tail effect.
The core ideas of this novel are two points. The first point is that cloud computing will amplify people's abilities, and the improvement of computing power will amplify people's abilities. The second point is that computing is power. So when a new thing like Bitcoin comes out, it seems that the world written in my novel is becoming a reality. When Bitcoin was introduced to China from 2008 to 2010, many people had already heard of Bitcoin, but did not pay attention to it. In fact, to understand a thing like blockchain, some knowledge background is needed.
In addition, I would like to introduce a book, which is "Out of Control" written by Kevin Kelly. This book was written in the 1990s, but this book is very forward-looking and has a chapter that introduces the development of cryptocurrency. Pioneers, but these pioneers later became martyrs, what was the reason for their failure? In fact, blockchain needs to be based on three core technologies, and these three technologies are gradually maturing. The first technology is asymmetric encryption. In 1985, elliptic curve function encryption was already very mature, but unfortunately it was implemented in a centralized way. What are the risks of centralization? That is, when issuance If the currency company collapses or the founder is arrested, or the central server is attacked, it will cause the system to collapse, so it failed later. In 2000, someone began to introduce peer-to-peer technology into cryptocurrency for the first time, taking the lead in realizing distributed cryptocurrency. However, it also failed later. The reason is very simple, that is, there is no way to find a way to solve double payment (the same money is used). twice). Until 1997 AsiaWhen Beike proposed proof of work, Halfini expanded this technology into a reusable proof of work in 2004, so the Bitcoin white paper was successfully published in 2008.
And the carefully designed technical solutions in Bitcoin later seemed to be very advanced. For example, in 2014, Snowden revealed that elliptic curve function encryption is unsafe because the US National Security Agency has set up a backdoor in this encryption standard, giving the NSA an unknown method to weaken this curve. , at that time many people exclaimed that Bitcoin was dead and that the system might collapse, but later Satoshi Nakamoto did not use the encryption standard promulgated by the National Security Agency, but used a very rare curve.
To give another example, after hashing twice, a quantum computer cannot threaten the Bitcoin address and cannot decipher the Bitcoin private key from the address. What’s more interesting is that Satoshi Nakamoto also adopted a weird transaction method called a change mechanism. The change mechanism is that the remaining balance of each transaction is transferred to a new address. Now it seems that this is actually for the purpose of Prevent quantum computers, because the public key of a Bitcoin transaction will only be exposed on the blockchain during the transaction. You only need to transfer the remaining money to a new address during each transaction. In fact, you The public key will not be exposed on the blockchain.
So judging from so many details, it can be said that Satoshi Nakamoto is a bit like a person who is extremely careful, so many people think that he is not a person, but an organization.
I just mentioned why the proof-of-work mechanism was introduced to the blockchain and Bitcoin, and this cryptocurrency was successful? Because the proof-of-work mechanism is actually hash calculation. Why is calculation so important to the blockchain? ?I can give a very easy-to-understand proof through such a table.
This table shows that the real world and the digital world are actually in a mirror relationship. The real world can also be called the atomic world. In the real world, things are randomly distributed and random. In the digital world, everything is generally Pseudo-random. In the real world, there are no two identical leaves. Everything on the Internet can be copied. In the real world, it is a normal distribution. In the digital world, it is a power law distribution. It is the Matthew effect + long tail effect. . In the real world, things are competitive resources, which are exclusive resources. For example, if I own a microphone or a glass of water, others cannot own it. All resources in the digital world are non-competitive resources. For example, I transfer a document to another person, but in fact, this document cannot be transferred like a book in reality, because this document may be saved infinitely in my computer or other storage media. A copy, so based on such a mirror relationship, we can ask the question, why is it so difficult to copy exactly the same thing in the real world? This question can be turned into whether you can create a perfect crystal in reality, you can create A perfect crystal can actually copy exactly the same thing, but the third law of thermodynamics tellsTell us, if you want to create a perfect crystal, you need absolute zero, and you have to invest a huge amount of energy. In turn, through this symmetrical thinking, we can ask the question, that is, in the digital world, on the Internet, you have to It is also very difficult to achieve this kind of competitive resource by preventing something from being copied. To achieve such a competitive resource, a huge amount of personnel consumption is required, which is computing. The more computing power invested, the higher the barrier against double spending, which is why computing matters.
So since the real world and the digital world have such a mirroring relationship, the blockchain can actually be understood as the reverse machine of the printing press. I like to use such a very vivid metaphor to define the blockchain as the printing press. Reverse process.
Why is the printing press so great? In fact, before the birth of the printing press, human knowledge and information were competitive resources. Whether it was the Bible or martial arts secrets, they were all competitive resources. But after the birth of the printing press, this knowledge and Information has become a non-competitive resource that can be copied on a large scale, or the marginal cost of copying is almost equal to 0, so there is the subsequent information revolution. With the Internet, the Internet is actually an enhanced version of the printing press. But the problem with the Internet is that it is difficult to transfer competitive resources in the digital world. This is also the reason why some cryptocurrency pioneers failed in the 1990s. Blockchain solves this problem. It is the first to realize competitive resources on the Internet. The first competitive resource is of course Bitcoin, which is the first domino to be erected. After the first card falls, we can imagine that the second and third cards will fall as long as they have value attributes. They are all very suitable for using blockchain for registration and circulation, because the Internet is suitable for things with information attributes, so we say that the Internet is an information transmission protocol, and blockchain is a value transmission protocol. In fact, all resources with value attributes are It is very suitable to be combined with the blockchain.
So I don’t think the blockchain will replace the Internet. The blockchain itself is a parallel world of the Internet. It is to do some things that the Internet cannot do, so it may propose many business models. In my opinion, it is not It is unrealistic. For example, it combines things with information attributes and business scenarios with blockchain. In fact, I think it is not that appropriate, because scenarios with information attributes are suitable for the Internet, and only scenarios with value attributes are suitable for "blockchain." +".
Let’s further deepen the mirroring relationship between the Internet and blockchain. The carrier of the Internet is often software, and the carrier of blockchain is generally protocols. Software needs to apply for patents to establish its own patent barriers. On the contrary, with blockchain, most blockchain projects are open source, and you are very welcome to copy it. The code does not need to establish such patent barriers or moats. The main body of software development is usually a company, and the main body of blockchain development is often a community or foundation, which is a very loose organizational form. Software requires constant iterative upgrades, but iterative upgrades of protocols are very difficult, so they are generally very stable, because protocol upgrades require allThe adoption of network consensus is of course very, very difficult. That’s why there are so many Bitcoins. The software can be maintained and updated, and the protocol is that it cannot be shut down after it is started, and it runs 24 hours a day. Based on this kind of thinking, we can solve many doubts in our hearts. For example, in 10 years ago, many experts or big names in the investment community believed that although Bitcoin was a pioneer, it did not necessarily have the last laugh. How to prevent being defeated by latecomers? This is a typical Internet thinking. Internet thinking regards Bitcoin as a software. Through technological upgrades, latecomers may catch up, just like the browsers in the 1990s. Later, the early browsers were defeated by the newcomers. But in fact, Bitcoin cannot be regarded as a kind of software, but a protocol. The method of implementing this kind of blockchain is already a minimum feasible solution, and there is not much room for optimization.
Many people understand blockchain as the fifth paradigm revolution, because it is based on the summary of technological updates in the past few decades, which means that such a paradigm revolution, a leap-forward revolution, will be completed approximately every two years. The 1970s were mainframes, the 1980s were PCs, the 1990s were the Internet, the 2000s were the mobile Internet, and the blockchain was born in the 10s. The trend behind this is actually a trend of decentralization. Mainframes are in scientific research institutes or military institutions. PCs have entered families. The Internet has entered tens of millions of people. Mobile Internet has pervaded the world. In all aspects of life, blockchain has become more decentralized, and there is no longer even a central server. There is another detail here, that is, the time of the blockchain was calculated from January 1, 1970. Why does it have such a feature? In fact, it is because many programming languages ​​are derived from Linux systems, and Linux is derived from mainframes. , so it has the imprint of such an era invisibly.
In fact, there is a deeper evolutionary law behind it, such as the three stages of asset evolution. The evolution of assets can be divided into three stages. The first stage is the confirmation of asset rights, which is the equityization of assets and the confirmation of asset rights. It can then be transferred as a whole, so it's kind of like the solid stage of the asset. The second stage is asset securitization. After securitization, the assets can be divided and transferred, and their liquidity is obviously stronger. It is a bit like the liquid stage of assets. The liquid stage also has its limitations. For example, the business requires a container. , this container is the platform for assets, and assets still cannot flow across platforms. Only after the assets are blockchainized, that is, after the assets are put on the chain, will they truly enter a gas phase, because everyone can manage assets through their own private keys, whether it is Equity, income rights, debts, intellectual property rights, etc., as long as they are assets with this value attribute, they are suitable for registration and circulation using the blockchain, so they are no longer limited by the platform, because everyone can complete it through their own wallet. The process of asset transfer does not require a centralized authority or a centralized trading place. More broadly, many people have summarized the stages of blockchain evolution. The first stage was in 2009 with Bitcoin as the Cryptocurrency represented bystage to solve value transfer issues, which can be understood as the 1.0 of blockchain. In 2017, the era of issuing virtual assets through smart contracts emerged, represented by Ethereum, which can be understood as the 2.0 of blockchain. We believe that we will enter the third stage in 2020, using smart contracts to issue physical assets or help real assets to be put on the chain. The blockchain will eventually move away from the virtual to the real and serve the real economy. So Babbitt is doing the third stage, which is our prediction of the future development trend of the blockchain.

❹ How to judge whether a blockchain project is worth investing in?

1. Project details

Project details are generally published by the project party in certain ICOs On the platform, the platform is responsible for review, and detailed relevant information must be submitted when publishing. Available for user query. The following are what we need to refer to:

◆Whether the project team member information is fake

◆Whether the official website has been recently filed

◆Whether the total project quota is reasonable

◆Whether the additional issuance is excessive

◆Whether the project token allocation is reasonable

◆Whether the project development plan and development plan are clear

II. Product Analysis

Type: application, platform, underlying technology

Carry out corresponding analysis based on different blockchain projects to determine whether the project is suitable for development through blockchain technology and compare Analyze existing products in the industry. For example, a certain project is currently building a decentralized content distribution platform. We can refer to the better TOUs in the industry. As a unicorn in the field of content distribution, Toutiao has grown since its launch in 2012 and now has 500 million registered users and nearly 100 million DAU.

User composition: advertisers, content producers, content readers,

Content ecology: UGC+PGC content generation model has become complete, content composition is diversified, graphic information + Short video + Live broadcast

Profit model: e-commerce advertising, information flow advertising to monetize traffic,

Product advantages: large number of users, classified push of information based on specific algorithms, user experience Good, user habits are developed

Financing experience: Series C, US$1 billion

Based on the above information and comparing it with the project’s white paper, determine what are the real advantages of this blockchain project? If the project white paper cannot clearly describe the product architecture and just talks about concepts, then it is very likely that the product is unreliable.

3. Market analysis

Competing products: not only Sina, Sohu, Tencent, NetEase, Phoenix, Yidian, Zaker, Online News, Zhihu Daily and other major platforms. There are also a series of vertical content products competing with it.

Competition: A large number of users have developed fixed information acquisition habits, which indicates that the customer acquisition cost of the new platform will increase significantly

4. UseUser and usage scenario analysis

◆Content readers: obtaining information, entertainment and relaxation, skill learning, emotional expression, eye stimulation, policy interpretation, consumption decision-making, etc.

◆Advertisers: attract traffic, promote products, and create brand tone.

◆Content producer: Produce high-quality content, receive advertisements, and earn advertising fees.

5. Analysis of industry issues

◆The platform’s definition of effective traffic and recommendation mechanism lead to unstable income for content producers

◆The impact of advertising placement on users The impact of experience

◆The effect of information flow advertising on certain types of products is poor

Attachment: A summary of recent projects on a blockchain crowdfunding project website

◆Internet of Things: Waltonchain

◆Social communication platforms: SNC, Matchpool

◆Asset trading: OmiseGo, OpenANX, Bytom, Gongxinbao

◆Cloud storage technology: STORJ, iex.ec

◆Application distribution, MobileGo

◆Electronic wallet: Status, Monaco

◆Content distribution: YOYOW

◆Smart Investment: CoinFeed

◆Smart Contract: Aeternity

◆Digital Advertising: YouWiFi, BAT

◆Company : Dcorp

◆ICO crowdfunding, venture capital fund: Onplace

◆Blockchain transactions: ICOcoin, Quantum Chain Qtum=

◆Medical care: Cloud Medicine Chain HIS, medical chain

◆Entrepreneurship incubator fund: Starta

◆Blockchain technology application

◆Digital assets: Tenx, Ruizi Chain, ZenGold< /p>

◆Game account system: ugChain

◆New media: Cloud Chain

◆Election: Election Chain ELC

◆Asset exchange: SWFT Platform

◆Copyright: IPC Intellectual Property Chain, Printing Chain

◆Computing Power: SONM

6. Technical Strength Analysis

◆ Whether the core technology is innovative and industry-forward

◆Technical feasibility and implementation difficulty

◆Whether the product type can give full play to the advantages of blockchain technology

◆Whether the project releases a test network

◆Whether the project is open source, generally open source projects will be uploaded to github,

◆Which blockchain will be developed based on

◆Which consensus mechanism to use

7. Team composition analysis

◆Whether there are experts in the team

Whether it is technology experts: such as stratisCEO Chris Trew , Eyal Hert from the Bancor founding teamzog, investors such as Tenx include Ethereum founder Vitalik Buterin and Fenbushi Capital partner Shen Bo.

The initiator of a certain blockchain product crowdfunding project is Yang Mouke, the former co-founder of Bitcoin China, who launched the ICOcoin project. Or maybe the initiator of the blockchain project is Li Moulai, the "richest man in Bitcoin" in China, launching the Press one project. This can all mean that this project is reliable in a certain sense. Of course, there are exceptions, such as the recent case of Mr. Li, whose project caused outrage in the entire circle.

◆Is the team structure scientific?

Legal consultants, industry consultants, project management committees, third-party organizations

8. Reference blockchain project rating websites< /p>

Relatively reasonable, there are many rating websites, and the rating standards of each platform are also different. There may be a big gap in the ratings given by the same project on different platforms. At this time, we are needed

I have a deep understanding of the basic knowledge related to blockchain and am capable of certain self-judgment. Don’t trust experts. Many so-called experts may have interests tied to the sponsors of blockchain projects.

9. Direct communication

The last point is also the most important. Whether it is a face-to-face road show, or communication in a forum or community, people can intuitively understand whether the initiator of this project is reliable. Whether it is a blockchain product project or some technical questions, the project side can answer them. Whether it is reliable or not can be known once tested.

❺ Eight major ecosystems help Digital Life Chain DC become the most potential blockchain project

With the rapid development of the blockchain industry ecology, more and more projects have actually been implemented. In the future, blockchain technology will continue to accelerate its widespread application in industrial scenarios, deeply integrate with real economic industries, and form a number of "industrial blockchain" projects, which will become the application trend of blockchain technology.

In terms of market size, the scale of the global blockchain industry is growing rapidly, and application scenarios continue to expand. Thanks to its intermediation, good traceability, and difficulty in tampering, blockchain technology has profound transformation potential in finance, technology and other fields. Since 2013, blockchain application scenarios have continued to penetrate from digital currency and mining machine manufacturing to finance, supply chain, copyright, medical and other fields, providing sufficient impetus for the development of the blockchain industry. According to data, from 2013 to 2019, the global blockchain market showed steady growth as a whole, reaching US$122.26 billion in 2019.

DC’s Chinese name is Digital Life Chain, which is the world’s first pan-life digital service application platform.

DC is a full ecological platform based on and serving the life service industry. It mainly connects consumers and the life service industry to enable better communication between them and enable the service industry to improve their performance in a timely manner.Serve consumers effectively. The ultimate goal of blockchain technology is to meet people's needs, so DC hopes that industries closely related to people's daily lives can embark on the fast track of blockchain development.

The DC platform is based on all the content of the industry application layer, including blockchain e-commerce, social platforms, charity, entertainment, real estate industry, tourism, electronic games, advertising precision marketing, and unifies them into society The life service platform is committed to combining blockchain technology with areas closely related to people's lives to ensure the creation of a platform for real industry implementation. Blockchain technology and digital currency wealth are no longer obscure and obscure in the clouds, but integrated into every aspect of people's lives.

In all subsequent ecosystems opened, DC will be used as a platform currency and a media currency for the payment and circulation of all ecological services, such as the payment of platform product purchase fees, the use of platform ecological functions (information release, Service fees for merchants and enterprise functions), payment for enjoyment consumption such as games, entertainment and travel, etc.
