1. What is data blockchain (BlockChain)
Blockchain is a new application of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. model. Blockchain is an important concept of Bitcoin.
It is essentially a decentralized database. At the same time, as the underlying technology of Bitcoin, it is a series of related data using cryptographic methods. Each data block generated contains a batch of Bitcoin network transaction information, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block.
(1) Income in Blockchain Extended Reading in Chinese and English
Most public blockchain chains are limited by scalability. The biggest feature of blockchain technology is decentralization, which requires all ledgers in the network to handle the accounting process. Distributed accounting has high security, low misoperation rate, and is also politically neutral and correct.
However, while blockchain technology embraces these characteristics, it sacrifices scalability, cannot meet personalized supervision, and is slightly insufficient in protecting data privacy. Moreover, as the number of ledgers increases, the interaction delay will increase exponentially, which means that the more ledgers in the blockchain network, the higher the latency will be.
2. What is blockchain ICO/private equity? What are the risks of ICO and how to make 100-fold returns
ICO: initial coin offering, also called the public issuance and sale of tokens, corresponding to the stock market IPO. Just like the blockchain technology itself, ICO is a new financing model of the blockchain that allows everyone to become a "shareholder" of the project. Holding tokens is equivalent to holding equity. After the token sale is completed, trading will usually begin on the exchange. ETH is the first successful ICO project using BTC. The general way to participate in ICO is ETH or BTC. In the early days, BTC financing was more common, but now it is basically ETH. ETH is the hard currency of ICO.
Private placement: Blockchain projects that generally do not participate in public offerings, only a small number of institutions or funds have quotas.
Tangtang has been participating in the blockchain ICO since March last year. At that time, it was nicknamed the "Yunbi Entertainment City". The "Jubi Casino" was selling new coins every day, and almost everyone was 5-100 times, and the daily fluctuations are several times or dozens of times. 9.4 The country has concerns about the risks of ICOs. Many ICOs have had their coins withdrawn, major exchanges have been forced to close or even go overseas, and some project developers have even been warned. The price of many ICO coins has almost halved and then halved, reaching the cost price of the ICO.
But facts have proven that many projects that had their coins refunded basically increased 10-20 times during the bull market in December 2017 and January 2018. Many people undoubtedly broke their legs. Generally speaking, investment projectsIt is much more stable than currency speculation. Due to market fluctuations, it is difficult to hold on to currency speculation, such as 94. Many of Tangtang’s friends cut their stocks and left the market with losses.
So far, Tangtang and my friends have invested in at least dozens of projects, and have experienced things like Hero Chain Runaway, Mondo Scammer, and Fcoin Hundred-fold Coin. Overall, we have experienced a lot. There have been many pitfalls and many rewards. The overall return in 2017 was about 10 times. Since January 2018, the investment projects have basically achieved zero break-through, and all have achieved good results of at least 3 times.
Tangtang believes that the main risks of blockchain ICO are:
1. Teams running away: Many teams are small workshops with low visibility or even non-existence, white paper It’s also a matter of piecing everything together, and you can even do Taobao ghostwriting for a few hundred yuan
2. Agent investors run away: There are many unscrupulous agents. If the currency has multiplied many times on the exchange, they will tell you that you didn’t invest. If it breaks, I will give you tokens. Some proxy investors even run away directly with ETH, which has ruined the industry atmosphere.
3. The white paper cannot be fulfilled: The road map in the white paper determines the future development direction of the team. Many project parties have no intention of completing the project at all, and the road map inside is basically written in random order. In addition, those projects that directly specify which exchange to list on are basically scammer projects. Many exchanges have agreements with the projects. They are not allowed to leak the information until the listing is announced, otherwise the qualification for listing will be cancelled.
4. Blockchain technology: Ordinary people do not understand the underlying technology of blockchain, do not understand the necessity of using blockchain in this project, and cannot identify the technical level of the project. For example, GitHub does not will see.
How to make a hundredfold profit:
Tangtang discovered that the primary market (ICO/private placement) and the secondary market (coin speculation) are mutually transformed. When the primary market breaks down seriously, everyone will go to the secondary market to speculate in coins. When the secondary market becomes more and more difficult to play, everyone will return to the primary market to hunt for gold. After September last year, there were basically no projects in ICO. Everyone was speculating on coins. As a result, after the bull market came, most of these very few ICO projects were more than 10-20 times higher. ICO was very popular in December last year. As a result, when it was launched in January, many coins broke and many people went to the secondary market to speculate in coins.
Therefore, in fact, the bear market is a good time to invest in projects. When the project comes online, it will be a bull market, and you can basically make considerable profits.
However, the popular projects are basically reserved by large institutions, and retail investors can only have access to ordinary projects, and the risks of ordinary projects are slightly higher. Therefore, most people can only participate in investments with institutions.
To this end, Tangtang and her friends have opened up the ICO section to identify and screen good blockchain projects for everyone.This project allows everyone to participate in investment. We have a professional blockchain technology team to analyze the feasibility of the project, and will also conduct on-site inspections of blockchain projects. If there are big names in the blockchain currency circle, we will also seek verification from them. Let the scammer projects have no way to hide. For high-quality and popular blockchain projects, our organization will directly contact the blockchain project parties to get the best ratio and the largest quota.
3. What are the jargons in the blockchain and what do those jargons mean?
Currency circle: refers to the group of people who focus on speculating on coins and even issue their own digital currencies to raise funds. , Generally speaking, blockchain project parties, exchanges, and some blockchain media all belong to the currency circle.
Chain circle: refers to the group of people who focus on the research and development and application of blockchain or the underlying protocol of blockchain. Without the technical support of the chain circle, the currency circle cannot exist. The implementation of future blockchain scenarios will also rely on the technical support of the chain circle. The popularity of blockchain technology has caused many related top domain names to be registered
Mining circle: refers to the group of "miners" who focus on "mining".
Coin speculation: refers to the act of repeatedly buying and selling digital currencies through a trading platform in order to obtain high profits.
Stud: It is the transliteration of the English Show Hand. It was originally a noun in gambling games. It is the act of putting out all the available chips in your hand at one time. Extended to blockchain investment, it means investing all your available assets in digital currencies for the purpose of speculating on currencies, which has the meaning of "taking a gamble".
Buddhist currency holding: refers to the behavior of not caring about the price trend of cryptocurrency after holding the currency. No matter how low the price of cryptocurrency assets falls, they will not reduce their holdings of cryptocurrency.
4. 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.
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.
A public key is a key that everyone has. you have 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 questions and answers: Can youCan you explain to me what 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 Ga Zi's interest, I also felt a small sense of accomplishment and continued: "Of course, the above is just an example. In fact, the blockchain does not really allow the villagers toGo get pen and paper to help 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, 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. Accounting, then Li Si can get a small red flower as a reward ~ This small red flower is generated by the blockchain system, itselfIt has no value, 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 is a huge difference. The average investor cannot judge a virtualThe value of the pseudo-currency itself depends entirely on the relationship between supply and demand to determine the price, 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 carefully conducted the above analysis??
5. How to make money with blockchain and how to make money with blockchain
Block The development of chain technology has made it a new currency and a new way of making money. So, how to make money with blockchain and how to make money with blockchain?
itialg) project to obtain income, this is a new financing method in which investors can directly invest in ICO projects and obtain newly issued cryptocurrency.
Again, you can make money through trading. Cryptocurrency trading refers to the buying and selling of cryptocurrencies, that is, investors can earn profits by buying and selling cryptocurrencies. Investors can buy and sell cryptocurrencies on exchanges, as well as on other platforms. In the process of trading cryptocurrency, investors can make profits by buying at low prices and selling at high prices.
You can also make money by developing applications. Investors can develop applications based on blockchain technology to gain income. Blockchain technology can be used to develop various applications such as financial services, smart contracts, supply chain management, investmentInvestors can develop applications based on blockchain technology to gain revenue.
In short, there are many ways to make money using blockchain, including mining, investing, trading, and developing applications. Investors can choose the appropriate method to obtain returns based on their own circumstances. However, before investors use blockchain to make money, they also need to understand market dynamics and control risks.
6. What are some professional terms in the currency circle
Explanations of 26 common terms in the blockchain industry1. Blockchain——Blockchain< /p>
Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. is a shared distributed ledger where transactions are permanently recorded through appended blocks.
2. Block——Block
In the Bitcoin network, data will be permanently recorded in the form of files. We call these files blocks. A block is a set of records of some or all of the latest Bitcoin transactions that have not been recorded by other previous blocks.
3. Node - A copy of the ledger operated by participants in the blockchain network.
4. Decentralization
Decentralization is a phenomenon or structure that must appear or exist in a system with many nodes or in a group with many individuals. The influence between nodes will form a non-linear causal relationship through the network.
5. Consensus mechanism
The consensus mechanism is to complete the verification and confirmation of transactions in a very short time through the voting of special nodes; for a transaction, if the interests are irrelevant If several nodes can reach a consensus, we can think that the entire network can also reach a consensus on this.
6. Pow - Proof of Work
Proof of Work refers to how much currency you get, depending on the workload you contribute to mining. The better the computer performance, the more money will be allocated to you. There will be more mines.
7. PoS - Proof of Stake
Proof of Stake, a system of interest distribution based on the amount and time of currency you hold. In POS mode, your "mining" The income is proportional to your currency age and has nothing to do with the computing performance of your computer.
8. Smart Contract
Smart contract is a computer protocol designed to spread, verify or execute contracts in an information-based manner. Smart contracts allow trusted transactions to be made without third parties, which are traceable and irreversible.
9. Timestamp
Timestamp refers to a string or encoded information used to identify the recorded time and date. The international standard is ISO 8601.
10. Turing completeness
Turing completeness refers to the ability of a machine to perform any calculation that any other programmable computer can perform.
11. Dapp——GoA centralized application
is an open-source application that runs autonomously, stores its data on the blockchain, is incentivized in the form of cryptocurrency tokens, and operates with a protocol that displays proof of value .
12. DAO - Decentralized Autonomous Organization
It can be thought of as a company that operates without any human intervention and hands all forms of control to a set of uncontrollable entities. Broken business rules.
13. PrivateKey - Private Key
A private key is a string of data that allows you to access a token in a specific wallet. They, as cryptocurrencies, are hidden except from the owner of the address.
14. PublicKey——Public key
It appears in pairs with the private key. The public key can calculate the address of the currency, so it can be used as a certificate for owning the address of the currency.
15. Mining machine
A computing device or software that attempts to create blocks and add them to the blockchain. In a blockchain network, when a new valid block is created, the system will generally automatically give the block creator (mining machine) a certain number of tokens as a reward.
16. Mining pool
It is a fully automatic mining platform that allows miners to contribute their own computing power to mine together to create blocks and obtain block rewards. And the profits are distributed according to the proportion of computing power contribution (that is, the mining machine is connected to the mining pool - provides computing power - obtains income).
17. Public chain
A completely open blockchain refers to a fully open blockchain that can be read by anyone, anyone can send transactions, and transactions can be effectively confirmed. People around the world can participate in system maintenance, and anyone can read and write data through transactions or mining.
18. Private chain
A blockchain where write permission is only for a certain organization or a specific few objects. Read permissions can be open to the outside world, or restricted to any degree.
19. Alliance chain
The consensus mechanism is a blockchain jointly controlled by a number of designated institutions.
20. Sidechains
Pegged sidechains technology will enable the transfer of Bitcoin and other digital assets between multiple blockchains. This This means that users can access the new cryptocurrency system while using their existing assets.
21. Cross-chain technology
Cross-chain technology can be understood as a bridge connecting various blockchains. Its main application is to realize Atom transactions, asset conversion, and partitioning between blockchains. Information exchange within the blockchain, or solving Oracle problems, etc.
22. Hard fork
