㈠ Why is it said that domestic blockchains are all lies
Blockchain unexpectedly ushered in a big explosion in 2018, and the world was suddenly filled with "overnight The dream of "getting rich instantly" and the "copper smell" of various virtual currencies have led many people to dive into the "sugar-coating" wrapped in blockchain. Will they realize their dream of getting rich in the huge bubble wave, or will they be treated like "leeks" and be cut off and bankrupt?
At this juncture, some people in the industry pointed out, "Blockchain is a good thing, but the current domestic use of blockchain is a lie." Such people may have been "robbed" in the currency circle, and use these words as a declaration of their poverty. He may also be a business leader in the blockchain circle. After reviewing the situation, he can see the various shortcomings of the current development of the blockchain and draw a comprehensive analysis and conclusion.
No matter who they are, this kind of statement must come from the understanding of the current mixed state of the currency circle and the dim prospects of blockchain technology, and this is not difficult to understand. Binance and Huobi Pro, international large-scale digital asset exchanges, have repeatedly encountered hacker attacks, resulting in the loss of user assets. The protection of website security mechanisms and the maintenance of user information and data are extremely unsatisfactory.
People who have suffered losses in the currency circle have turned their attention to the chain circle. However, what disappoints users again is that although the chain circle has great prospects, due to immature technology, the blockchain in all walks of life The chain layout is still in the conceptual stage and it is difficult to take substantive actions. Not only that, even blockchain media based on fairness and facts have been exposed to pay to recommend coins to induce investors, and promote ICOs in disguise in the name of "private placement", which is actually an important service for "cutting leeks" tool.
Recently, the "blockchain+Tibetan tea" fund -raising fraud case of a blockchain company in Shenzhen has made the chain circles cool more, and the "world's first digital currency" is about to issue "the world's first original digital currency". The signboard defrauded more than 3,000 investors out of 307 million. However, blockchain companies of this scale and approach are emerging one after another, and it is difficult to distinguish the true from the false.
However, we admit that there are indeed deficiencies in the current domestic blockchain development, but can we generalize and give blockchainAre chain companies labeled “fake”?
We should admit that every stage of development of emerging things is bumpy, and even criticized repeatedly. Just like the Internet 20 years ago, how many people could have predicted its earth-shaking development at that time? The same goes for blockchain.
Moreover, at present, domestic Internet giants such as JD.com, Tencent, Ali, etc. from all points such as financial trade, entertainment, leisure, logistics, and medical treatment; Blockchain has made breakthroughs in industries such as media and games one by one; the country has also introduced blockchain technology in strictly regulated industries such as energy and electricity; there are also Leou’s blockchain tourism layout and Ant Financial’s blockchain in Xiongan New Area Technical housing rental cooperation, etc. It can be seen from this that the blockchain layout is not a solo effort of unknown companies. Each has strong support from Internet giants and the government. Amid the collective excitement, how can the “scam” of blockchain gain confidence?
Although domestic blockchain companies are still in their infancy in terms of technology and application, this does not negate the blockchain itself and the overall situation of domestic blockchain. As the People’s Daily said, “Blockchain has an unprecedented bright future.”
㈡ Several people around me have been deceived by blockchain
Nowadays, the concept of "blockchain" is very popular, and blockchain scams are also coming. Many people who dream of getting rich overnight are led into a "cage" and become "leeks". Harvest.
Trap 1: Blockchain is about issuing coins to make money
Fraud tricks
Blockchain is an epoch-making technological change. This is to guide you through The last train on the road to wealth and freedom. If you miss ten thousand times of Bitcoin, do you still want to miss ten thousand times of XXX coins? ××× currency, Bitcoin is even more awesome, its potential is unlimited! Today, if you invest in our ××× coins, you can quickly achieve financial freedom.
The truth
Equating "blockchain" with "issuance of currency" is a stolen concept. Blockchain is a technology, and currency issuance is an act derived from blockchain technology. At present, the vast majority of blockchain applications that focus on issuing and speculating coins are suspected of illegal fund-raising.
Trap 2: Buying coins with the promise of high returns
Fraud routine
If you miss ten thousand times of Bitcoin, you will also miss ten thousand times of ××× coins ? ×××coin is more powerful than Bitcoin, and its potential is infinite!
The truth
From directly setting up a website to sell coins and collect money, to cloning Bitcoin and renaming junk altcoins, to so-called ICOs... In recent years, scammers have also kept pace with the times and upgraded their technology. However, the core of these routines will always remain the same - I can make you rich overnight. But the key point is that if the rewards were really that great, I would have made a fortune long ago. How could it be your turn to be a non-relative? You are not his father!
Trap Three: Decentralization can solve all problems
Fraud Routine
Join us, decentralized blockchain will change the world! We currently live in a centralized world: when you transfer money from the bank, you need to transfer it from the central system; when you make suggestions to the company, you need to report to the supervisor first... If it is decentralized, you can bypass the center and directly Do what you want to do, and there will no longer be a center to constrain you. Isn't this a way to change the world?
The truth
Decentralization is one of the most valuable features of the blockchain, but this feature is achieved by sacrificing its network efficiency, which not only decentralizes but also improves efficiency. There is currently no perfect solution. Moreover, decentralized applications are not suitable for all fields. It is a misunderstanding and trap to regard decentralization as "universal".
Trap 4: Having a white paper means practical application
Fraud tactics
In order to gain the trust of the masses, scammers will often release a white paper and Promote: "Utopias that are divorced from reality are useless. We are a project with real applications. And we have released our own white paper."
In the white paper presented, the founding team's Each member has a high degree of overseas education and has won a certain award; the technology of the project is described as very mature and has been applied. However, most of the white paper is written in English, and some technical terms are also difficult to understand.
The truth
In fact, if you look online, you will find that the academic qualifications of many team members are lies. In addition, blockchain technology is still in its early stages, and it is difficult to implement its applications. If you rely solely on a white paper to claim that there is an application, it is a kind of deception in itself.
Trap Five: Celebrity Platform is a Good Project
Fraud Routine
Some people say that blockchain applications are difficult, but our project is different from others. It is obviously better than other projects, which can be seen from the background strength behind us. You see, here are the famous investors ××× and ×××. They are blockchain technology experts and are very well-known in the industry. You can check their information online and you will know how powerful they are.
The truth
Looking for celebrity platforms has become a common fraud routine for many "blockchain scams". Because he doesn't have much strength, he can only rely on celebrities to "support the scene." Moreover, the possibility of celebrities being "touched" is not ruled out.
Trap 6: You can make money just by having a mining machine
Fraud routine
In addition to buying ourWith tokens, you can also buy our mining machines and make money while you're at it. Our tokens can be produced through this mining machine, and when the tokens are circulated in the market, we can wait for appreciation and make money.
The truth
First of all, mining with a mining machine requires costs, it consumes a lot of electricity, and the electricity cost is very high. Secondly, although you can get some tokens through mining, the price of the tokens will continue to fluctuate, and you may lose a lot of money.
In addition, ICO has been banned by the country, but in order to achieve the purpose of issuing coins, some blockchain projects have come up with the idea of selling mining machines to allow investors to mine and hold coins. This IMO method has been characterized as a "disguised ICO" and is also an illegal fund-raising behavior.
Trap 7: Collecting coins for WeChat transactions
Fraud routines
Some people make their circle of friends very impressive, making novice users feel trustworthy. The credibility is very high. Then he pretends to be a user who collects coins off-site and asks the other party to transfer the token first and then pay. After receiving the token, he turns his back and refuses to recognize the person, and then continues to look for the next prey.
The truth
Since the current token address cannot be associated with the user's identity, it is basically impossible to retrieve it after being deceived. Moreover, virtual currency is not legal tender. Even if the police call the police, the case will not be filed.
Summary reminder
The "high-end" blockchain is not something ordinary investors can play with. In the face of obscure professional terms and myths about wealth, it's best to stay away.
Moreover, the tricks of scammers are also advancing with the times, and they will use various means to improve their deception capabilities. Investors should remain vigilant and never be fooled by exaggerated profit returns and "celebrity effects". They must remember: high returns come with high risks, and prudent investment is king!
Excerpted from the Internet
㈢ Day 1 "Everyone Understands Blockchain" Thoughts on Listening to the Book
Actually, I have heard of blockchain before, and Speaking of Bitcoin, many people made a lot of money and became rich overnight because of it. Even now, there are still many belated people who want to join the blockchain, dreaming of making a fortune "for nothing."
But after the "Li Xiaolai Bitcoin Scam" incident broke out in 2018 (it seems), it had a huge impact. I actually liked Li Xiaolai quite a lot (because he is the idol of Uncle Cat, whom I admire) ), but because I didn’t understand Bitcoin at the time, I couldn’t understand the ins and outs of the entire incident (I didn’t want to be guided or incited by various public opinions).
Until today when I listened to the book "Everyone Understands Blockchain", I have a little understanding of blockchain, but after all, it is still relatively one-sided. I can only record the thoughts it triggered here. After all, It doesn’t matter what the knowledge is, what’s important is the thinking it triggers, right~
First of all, after listening to a brief introduction to blockchain, I remembered a video I watched before - Use it in the future Likes can be exchanged for money to buy things. See the video below for details (if you can’t see it, you can ask me for it).
I personally understand that blockchain and Bitcoin are actually a manifestation of value, but they are not as valuable as likes. After reading this book, I found that the blockchain has a permanent quota of 21 million, which means that this thing is scarce (that is, devaluation is unlikely). It depends on how everyone obtains value and trades value. .
Secondly, blockchain has four innovative technologies, which are actually consistent with what I think will be its future value.
The first is asymmetric encryption technology - which means it is very secure and cannot be easily cracked;
The second is distributed ledger - which can probably be understood as not Because a certain platform crashes, your value will be affected (when I was investing by myself, except for banks, I was particularly afraid that the investment platform would crash and affect my funds);
The third item is smart contracts - which means that as long as certain conditions are met, requirements and strictly enforce the contract (basically replacing the work of lawyers, so there is no need to argue in the future);
The fourth item is the consensus mechanism.
Then, whether you are investing in blockchain or stocks, you need to fully understand what you are investing in and be sure of your own judgment before doing it (I once analyzed stocks in order to invest in them) I read the company’s annual report and the analysis was very broken).
A blockchain project is like a company. Before investing in this company, you must first at least understand what the company does. The details are as follows:
First, look The legality of the project;
Second, read the white paper analysis;
Third, the project’s needs and application scenarios;
Fourth, the project Product model, user volume and user experience;
Fifth, how well the blockchain community is maintained, how many users there are, and whether they are active.
Sixth, whether there is a dedicated team to manage the market value of currency prices, the composition of the project team and consulting team, and whether there is past successful experience.
…………
Therefore, I personally recommend that people who are good at stocks play blockchain, just like entering advanced games. If you don't even understand the advanced ones, you will inevitably be "cut off".
Finally, I actually like the design logic of blockchain 4W1H, which is Why, Who, Where, How.
Why refers to the significance and value of this project.
Who refers to who can participate in this project.
Where refers to where to participate and circulate.
How refers to how to bring value continuously and stably.
In fact, for projects in enterprises, it is necessary to first clarify the 4W1H of the project in order to operate better.
The above are my thoughts after listening to this book. Maybe my understanding is one-sided, but as I said before, the important thing is not the knowledge, but the thinking caused by the knowledge.
Of course, if you have any misunderstanding, you are welcome to correct me~ Let’s work together and grow together.
㈣ How to interpret blockchain in the simplest way
Everyone can hear the word blockchain every day recently, so what is blockchain? Explanations such as "distributed, difficult to tamper, and consistent storage" are too technical and dry. Let me give you some popular science here: Blockchain is mainly designed to solve the trust problem between individuals who do not trust each other.
To give a popular example: It is said that Lao Li and Lao Wang live in the same village. Lao Li is a little short of money recently and wants to borrow some money from Lao Wang. As for Lao Wang, he was worried about what would happen if he defaulted on the loan after borrowing money from Lao Li, so he called in the "highly respected" village chief. But thinking about it, the village chief couldn't be trusted either. The village chief had even stolen other people's sweet potatoes in the past! what to do?
The blockchain method is: After Lao Wang borrowed 1,000 yuan from Lao Li, he then used a loudspeaker to shout in the village, "I, Lao Wang, borrowed 1,000 yuan from Lao Li today. Everyone Record it quickly." So everyone in the village recorded it in their own account books and kept it carefully. This is good, Lao Li can't rely on him anymore. Even if there are dishonest people in the village, there are still many good people. Lao Li can't find everyone in the village to secretly erase his loan records. In this way, the blockchain solved the trust problem of borrowing money between Lao Wang and Lao Li, who did not trust each other.
Before the emergence of blockchain, how did we solve the problem of trust between individuals who did not trust each other? It's simple, just find a "witness" who is "highly respected" and trusted by both parties, such as the village chief in the story, such as Alipay between the buyer and seller, such as the notary office, etc. However, it is possible that such "witnesses" may not always be honest, so the blockchain simply allows everyone to act as a witness.
Lao Wang is relieved, but Lao Li has a headache! Lao Li has to wait until everyone in the village has recorded the money before he can get the money lent to him. There is no uncle or aunt in the family who is slower. Therefore, there is still a certain distance between blockchain and application, and efficiency issues need to be significantly improved.
Recall how you usually trade with others: you can choose a beautiful dress in a physical store, confirm that the other party’s clothes are of good quality, and the other party confirms that your money is real money. , then we will pay and receive the goods face to face.
What if we are thousands of miles apart and neither know nor trust each other but still want to trade? Then there needs to be a third party that we all trust, which is the so-called consensus mechanism. For example: you can use a third party to witness the guarantee on TaobaoTo complete the transaction, the money is first given to Alipay - Alipay collects the payment and lets the seller deliver the goods - the seller delivers the goods - you confirm receipt - Alipay then gives the money to the seller.
However, what if this centralized organization does evil, and Dad Ma tears up the account books and refuses to admit that you gave the money, or joins forces with the seller to defraud you of money?
Or maybe the government lends you 1 million, and finally pays you back by issuing extra currency. The 1 million shrinks to 10,000, and you bear the loss of inflation. What should you do? ?
Is there a third party that is not controlled by any government or organization, can complete arbitration in an open and transparent manner, has records that will not be tampered with, and has no risk of running away?
Don’t worry, our protagonist blockchain technology solves this problem - the transactions between you can be witnessed by everyone in this blockchain system, and everyone’s small ledger will be recorded Your deal. If B denies receiving money from A, or if A says that he borrowed 300 yuan, passers-by A, B, B, and D will question him. How exactly is it done?
1) The system issues a small ledger to everyone, so that everyone has the right to keep accounts. We call it distributed accounting.
2) In order to encourage everyone to help others keep accounts, the system code is set to reward tokens such as Bitcoin to the keepers. In order to prevent a group of people from being blocked in keeping accounts, the tokens are also set to There are only a limited number of A, B, C and D who need to be calculated through the mechanism specified by the system. Only the fastest and best calculation can obtain the right to keep accounts. After recording, it is broadcast to everyone through the system. Everyone copies the same ledger. This is obtained through calculation. The reward process is called mining, and passers-by A, B, C and D who keep accounts are the miners.
3) One day, A, who originally recorded the transaction, Game Over, but the ledger still exists in other people's ledgers. Neither A nor B can deny it. We have written in code how to arbitrate and distribute, without the need for banks, governments, enterprises and other centralized organizations to serve as third-party witnesses (decentralization), and the direct point-to-point (P2P) transaction method is called decentralization.
4) The system packages multiple transactions into blocks and links them in chronological order to become the final ledger that everyone has. This is the blockchain technology
In fact, the block chain The simple understanding of blockchain as a ledger is only the simplest interpretation. If each of its characteristics is separated, it can be applied in many fields.
Now the traditional financial industry, securities firms, and investment institutions are rushing to enter the Internet of Things, games, storage, copyright, anti-counterfeiting, credit reporting, payment, prediction markets (gambling, etc.), communities and many other fields. The exploration and application of blockchain has already begun.
The Internet allows everything to be connected. Can blockchain make everything connected?Is it credible?
Let me explain the blockchain using the natural stones of heaven and earth:
All science, philosophy, morality... heaven and earth are included. Every thing and every culture is related to the Taoism of heaven and earth.
Blockchain naturally cannot escape the fate of heaven and earth: that is, smooth, random, infinite, and impermanent.
It is this strange stone, and the overall data movement on its surface. First, the whole is intangible. Second, the lines and points adhere to a pattern: the path of impermanence. That is to say, every line and every point they pursue is not a closed goal or a limited purpose. I can understand it better when I say this: when a painter paints a chicken, it has a purpose and an ending, while strange rocks, when created by nature, have no ending. Therefore, the phase is not closed, and the line and point data are not terminated. The technology of block connection is this way of destiny. Impermanence is invisible and has no end. (No centralization means formlessness, no closed form, no closed structure, no closed mind... just like "stone" to do things).
Confucius Lingshi Museum in Qufu, Shandong
Hello everyone, I am Pippi. I will use a few life examples to explain to you what blockchain is?
A decentralized, tamper-proof, distributed storage data block linking system that uses encrypted information as the link address is called blockchain
This thing is originally There are many high-tech composite products that cannot be simplified. No matter how simple it is, it takes a long paragraph, and it may not be clear.
The strict definition of blockchain refers to the design based on cryptography technology. Consensus mechanism, a distributed database technology in which multiple nodes in a peer-to-peer network jointly maintain a continuously growing, chained list ledger constructed of timestamps and ordered record data blocks. This technical solution allows any number of nodes participating in the system to calculate and record all information exchange data in the system over a period of time into a data block (block) through cryptographic algorithms, and generate the fingerprint of the data block for linking ( chain) and check the next data block, all participating nodes in the system jointly determine whether the record is true.
Blockchain is a general term for technical solutions similar to NoSQL (non-relational database). It is not a specific technology. Blockchain technology can be implemented through many programming languages and architectures. . There are also many ways to implement blockchain. Common ones currently include POW (Proof of Work), POS (Proof of Stake), and DPOS (Delegate Proof of Stake).system), etc.
The concept of blockchain was first proposed in the paper "Bitcoin: A Peer-to-Peer Electronic Cash System" by the author who calls himself Satoshi Nakamoto (Satoshi Nakamoto) individual (or group). Therefore, Bitcoin can be regarded as the first application of blockchain in the field of financial payments.
[Popular explanation]
No matter how big the system or how small the website, there is usually a database behind it. So who will maintain this database? Under normal circumstances, whoever is responsible for operating the network or system will maintain it. If it is a WeChat database, it must be maintained by Tencent's team, and Taobao's database must be maintained by Alibaba's team. Everyone must think that this approach is natural, but this is not the case with blockchain technology.
If we imagine the database as a ledger: Alipay, for example, is a typical ledger, and any change in data is an accounting type. We can think of database maintenance as a very simple accounting method. The same is true in the world of blockchain. Everyone in the blockchain system has the opportunity to participate in accounting. The system will select within a period of time, maybe within ten seconds, or maybe ten minutes, to select the person with the fastest and best accounting during this period. This person will do the accounting, and he will combine the changes in the database during this period with Changes in the ledger are recorded in a block. We can imagine this block as a page of paper. After confirming that the record is correct, the system will link (chain) the data fingerprint of the past ledger to this paper, and then This piece of paper is sent to everyone else in the entire system. Then the cycle starts over and the system looks for the next person who can do the accounting quickly and well, and everyone else in the system gets a copy of the entire ledger. This also means that everyone in this system has exactly the same ledger. This technology is called blockchain technology, also known as distributed ledger technology.
Since everyone (computer) has exactly the same ledger, and everyone (computer) has exactly the same rights, there will be no problem due to a single person (computer) losing contact or going down. The entire system collapses. Since there are exactly the same ledgers, it means that all data is open and transparent, and everyone can see the digital changes in each account. Its very interesting feature is that the data in it cannot be tampered with. Because the system will automatically compare, it will consider the account books with the largest number of the same number as the real account books, and the small number of account books with different numbers as others are false account books. In this case, it makes no sense for anyone to tamper with their own ledger, because unless you can tamper with most of the nodes in the entire system. If the entire system has only five or ten nodes, it may be easy to do, butIf there are tens of thousands or even hundreds of thousands of them, and they are distributed in any corner of the Internet, unless someone can control most of the computers in the world, it is unlikely to tamper with such a large blockchain.
[Elements]
Combined with the definition of blockchain, we believe that it must have the following four elements to be called a public blockchain technology. If it only has the first three points elements, which we will consider as private blockchain technology (private chain).
1. Point-to-point peer-to-peer network (peer-to-peer power, physical point-to-point connection)
2. Verifiable data structure (verifiable PKC system, non-tamperable database)
3. Distributed consensus mechanism (solve the Byzantine generals problem and double payment)
4. Nash equilibrium game design (cooperation is an evolutionarily stable strategy)
/>
[Characteristics]
Combined with the definition of blockchain, blockchain will realize four main characteristics: decentralized, trustless, Collectively maintained (Collectively maintained), reliable database (Reliable Database). And the four characteristics will lead to two other characteristics: open source (Open Source) and privacy protection (Anonymity). If a system does not possess these characteristics, it will not be considered an application based on blockchain technology.
Decentralized: The entire network has no centralized hardware or management organization. The rights and obligations between any nodes are equal, and the damage or loss of any node will not affect it. operation of the entire system. Therefore, the blockchain system can also be considered to have excellent robustness.
Trustless: Each node participating in the entire system does not need to trust each other for data exchange. The operating rules of the entire system are open and transparent, and all data contents are also public. , therefore within the rule range and time range specified by the system, nodes cannot and cannot deceive other nodes.
Collectively maintain: The data blocks in the system are jointly maintained by all nodes with maintenance functions in the entire system, and these nodes with maintenance functions can be participated by anyone.
Reliable Database: The entire system will be divided into databases so that each participating node can obtain a copy of the complete database. Unless it can control more than 51% of the nodes in the entire system at the same time, a singleModifications to the database on one node are invalid and cannot affect the data content on other nodes. Therefore, the more nodes and stronger computing power participating in the system, the higher the data security in the system.
Open Source: Since the operating rules of the entire system must be open and transparent, for the program, the entire system must be open source.
Privacy protection (Anonymity): Since nodes do not need to trust each other, there is no need to disclose their identities between nodes. The privacy of each participating node in the system is protected. protected.
[One of the meanings of blockchain: Solving the Byzantine Generals Problem]
The core problem solved by blockchain is not "digital currency", but information asymmetry and inconsistency. Under a certain environment, how to establish a "trust" ecological system that satisfies the occurrence and development of economic activities. This problem is called the "Byzantine Generals Problem", also known as "Byzantine Fault Tolerance" or the "Two Armies Problem". This is a difficult problem faced when information machines interact in a distributed system, that is, any point in the entire network When nodes cannot trust the other party they are communicating with, how can they create a consensus basis for secure information exchange without worrying about data being tampered with. Blockchain uses an algorithmic proof mechanism to ensure the security of the entire network. With it, all nodes in the entire system can automatically and securely exchange data in a trustless environment. For more introduction, please see "Bitcoin and the Byzantine Generals Problem".
[The second meaning of blockchain: realizing cross-border value transfer]
At the beginning of the birth of the Internet, the earliest core problem to be solved was information production and transmission. We can transfer information through the Internet It can be quickly generated and copied to every corner of the world with a network, but it still cannot solve the value transfer and credit transfer. The so-called value transfer here refers to a method that everyone in the network can recognize and confirm, accurately transferring a certain part of the value from a certain address to another address, and it must be ensured that when the value is transferred, the original address is reduced The transferred portion, while the new address increases the value transferred. The value mentioned here can be a monetary asset, or some kind of physical asset or virtual asset (including securities, financial derivatives, etc.). The results of this operation must be recognized by all participating parties, and the results cannot be manipulated by any one party.
There are also various financial systems in the current Internet, and there are also many payment systems provided by government banks or third parties, but they still rely on centralized solutions. The so-called centralized solution is to put all value transfer calculations on a central server (cluster) through the endorsement of a certain company or government credit. Although all calculations are automatically completed by the program, this center must be trusted.A person or institution that is attentive. In fact, through centralized credit endorsement, credit can only be limited to certain institutions, regions or countries. It can be seen from this that the fundamental problem that must be solved is credit. Therefore, the core issue of value transfer is transnational credit consensus.
In such a complicated global system, it is difficult to establish a global credit consensus system out of thin air. Due to the different political, economic and cultural conditions of each country, it is difficult for two countries to It is almost impossible for enterprises and governments to completely trust each other. This means that whether it is endorsed by the credit of individuals or corporate governments, even if the value exchange between countries can be completed, there will be huge time and economic costs. But in the long history of mankind, no matter how different the religion, politics and culture of each country are, the only thing that can reach consensus is mathematics (basic science). Therefore, it is no exaggeration to say that mathematics (algorithms) is the greatest common denominator of global civilization and the basis for the greatest consensus among human beings around the world. If we use mathematical algorithms (programs) as endorsement, all rules are based on an open and transparent mathematical algorithm (program), which can allow all people with different political and cultural backgrounds to gain consensus.
[Future Development]
The Internet will make global interactions closer and closer, accompanied by a huge trust gap. Currently, the existing mainstream database technology architecture is private and centralized. On this architecture, the problems of value transfer and mutual trust can never be solved. Therefore, blockchain technology may become the next generation database architecture. Through decentralized technology, it will be possible to complete the huge progress of mathematical (algorithm) endorsement and global mutual trust on the basis of big data.
As a specific distributed access data technology, blockchain technology uses multiple nodes participating in calculations in the network to jointly participate in the calculation and recording of data, and mutually verify the validity of their information. (anti-counterfeiting). From this point of view, blockchain technology is also a specific database technology. The Internet has just entered the era of big data, but from the current point of view, big data is still in a very basic stage. But when it enters the blockchain database stage, it will enter the big data era of real strong trust endorsement. All data here has acquired indestructible quality, and no one has the ability or need to question it.
Perhaps we are now at a major turning point - the early stages of a major transition that is almost as profound as the changes brought about by the Industrial Revolution. Not only are new technologies exponential, digital and combined, progress and changes, but more surprises may be ahead of us. In the next 24 months, the planet will grow more computing power and record more data than it has in all of history combined. In the past 24 months, this value increase may have exceeded 1,000 times. These digital data information are stillGrowing faster than Moore's Law. Blockchain technology will not only be used in the field of financial payments, but will expand to all current applications, such as decentralized Weibo, WeChat, search, renting, and even taxi-hailing software may appear. Because blockchain will allow humans to collaborate on a large scale in a trustless manner without geographical restrictions.
Blockchain is a technology based on which many applications have been produced, including all industry businesses related to data and information. Bitcoin is one of the most well-known applications. The popular explanation of blockchain is that if you buy a lipstick online, you first find the product you like and place an order with the seller. You first give the money to the intermediary platform. After the seller ships the goods and the buyer confirms receipt, the intermediary platform then transfers the money. Transfer it to the seller, because of the trust issue, both buyers and sellers rely on the intermediate platform, and the blockchain, as a decentralized distributed ledger database, focuses on removing this intermediate platform while solving the trust issue at the same time. In the blockchain, everyone has their own ledger to record everything that happens. If a seller takes money but does not deliver the goods during the transaction, this record will exist permanently and cannot be modified, and there is no need to interact with each other. To exchange information, the blockchain world will select the person's ledger that records the fastest and best quality at the same time node to copy, send and connect in series, and finally stack it up to form a block.
When everyone talks about virtual currencies, they often cannot do without the concept of blockchain. So what is the magic of blockchain?
Blockchain is an underlying technology, essentially a decentralized distributed ledger database. It sounds very high-end and out of reach, but it is actually very easy to understand.
For example, if you want to buy something on Taobao, the first thing you usually have to do is to open Taobao, find the product you want, place an order and pay the money to Taobao, which is the transaction intermediary. Taobao will pay the seller after receiving the goods and confirming receipt. This was originally just a transaction between me and the seller, but it has an additional "center", namely Taobao.
During the transaction process, this "center" has unlimited power and can even modify the bill at will. Therefore, the “center” often needs a strong backend to endorse it.
So, a man named Satoshi Nakamoto wanted to get rid of this center with infinite power. He wanted to create a decentralized system in which everyone is the center and everyone is the center. Have the authority to keep accounts. So, he created Bitcoin.
In the Bitcoin system, everyone has a small ledger to record every transaction that occurs. A transaction is only valid after being confirmed by a majority of people. If the seller doesn't deliver the goods, everyone's little ledger will record it, leaving him nowhere to escape.
At this time, you may have questions. Since it is only a publicLedger, so why is it called blockchain? This involves the issue of consensus. The blockchain system is a system composed of many "centers". The entire blockchain belongs to all individuals participating in accounting. At this time, new problems arise. A system must be in order to survive in the long term. If the bookkeeper can act recklessly regardless of the cost, it may happen that he originally just bought a mobile phone, but received a Tesla instead.
So, Satoshi Nakamoto invented a consensus method called PoW. This method increases the cost of bookkeeping for bookkeepers and prevents them from doing evil easily. PoW uses cryptography to require bookkeepers to compete for computing power to obtain accounting rights. The first bookkeeper to calculate the result can obtain the accounting rights of a block packaged from several transactions. At the same time, you will receive certain tokens as rewards. This is what we commonly call "mining".
Now that the bookkeeper has recorded a block containing several transactions, the system needs to be organized and sorted. It is impossible to have countless blocks distributed in the system in an orderly manner. So it is necessary to link all blocks end to end in chronological order. At this time, the blockchain was born. The core of blockchain is technology.
㈤ Several of my friends are playing with blockchain. Is it reliable?
Blockchain is also a relatively new thing, and many people are interested in it. For those who pay attention to blockchain, blockchain can be loved by many people, and it can also gain investment from many people. Many people particularly want to invest in blockchain, and they also hope to gain more by investing in blockchain. Much reward.
There are many people who want to invest in the blockchain, but they may not necessarily understand the blockchain, and they do not know how to operate the blockchain. If everyone around them invests in the blockchain, they themselves If you invest, you may suffer relatively large losses. Some people may have this question: Several of my friends are playing with blockchain, is it reliable? In fact, I think blockchain is not necessarily reliable. There are three main reasons why I say this:
First, blockchain is easily affected by the market.
The reason why I think blockchain is not necessarily reliable is because I think blockchain is easily affected by the market. When the market fluctuates greatly, the value of blockchain may change. decline, and it may not be able to recover as soon as possible. If some people invest because of the value of the blockchain, they may suffer relatively large losses and may lose all their money.
The above is my opinion.
㈥ Several thrilling blockchain stories
After sending Emily to school yesterday, she hurried home. The sixth of every month is the day for our Class 10 scheduled investment. When I turned on the computer, I was shocked. The day before, Bitcoin was still trading sideways at around 7,300 US dollars. Why did it suddenly become 6,400 US dollars? I rubbed my eyes. That's right, one nightThe decline was as high as more than 13%. Before, I subconsciously thought that it would break through the 7400 mark. I didn't expect that there is a principle in the bear market called "If it lasts for a long time, it will fall."
Of course, in the blockchain world, yesterday’s 13% drop is nothing new. We old leeks followed Li Xiaolai’s path to wealth and freedom and came to this “exciting” world. It has been more than a year, and although I haven’t seen the rainbow yet, I have experienced the wind and rain. During last year’s 94 policy, Bitcoin fell by 36% in a few days. At that time, I had money in Yunbi but I didn’t dare to buy it. Only now do I realize how stupid I was at that time. At that time, I really didn’t understand anything, not finance, blockchain, and investment. I only knew that Li Xiaolai was awesome, and the people who left comments under his column were awesome. I wanted to join them, and no one else. Stop me, whoever stops me, I will be in a hurry, this is the passionate All-in blockchain.
But precisely because of being too timid, there have been very few operations over the past year, and precisely because of the few operations, the losses have not been large. My own blockchain story is as plain as a glass of boiled water.
Yesterday, I watched a video program about blockchain stories in Tencent's "Talk to Strangers". In the program, three people were interviewed: Zeng Wen, a wage earner, and Colorful Shenyu, a big boss in the currency circle. and Liu Ke, a sophomore student.
Zeng Wen, a migrant worker with a junior high school education, first worked at Foxconn. He was so busy that he had to trot all the way to the toilet. He said that he was always bullied by others because he was too honest, and he did all kinds of hard work. Yes, but no money. Later, I met a girlfriend who treated him in every possible way just to lure him into a MLM organization. As a result, she lost all her parents’ hard-earned money of 60,000 yuan. She escaped from the MLM organization and was deceived into working in a rat barn. , the people behind use money to patch up the holes made by those in front, but naturally there will always be a day when the holes can’t be patched up. This has defrauded all the men, women, and children in the village. They owe a debt of 300,000 yuan, and they are so scared that they dare not go home during the New Year. Later, he thought that if he relied on part-time work, he would never be able to repay so much money in his life, so he was introduced to the blockchain by a friend again. In 2017, during the blockchain bull market, I earned 30,000 yuan a day at my peak. Within a few months, I suddenly became a millionaire, and the coins I bought increased tenfold or a hundredfold. Not only did he pay off all the money he owed before, but he also sent money to his parents, helped them buy rings, and bought the largest TV set in the village for his family. Of course I have reached a new "class". Taking the bus used to be too expensive, but now I take a taxi when I go out. I go to KTV to hire girls. I am romantic and happy. Happiness comes at a lightning speed. Who would have known that at the beginning of 2018, Bitcoin would drop from its highest price of $20,000 to just before liberation, and the myth of wealth creation would be broken so easily. Now he's back to his old self, but confident about the future. The host asked, where does your confidence come from? He said that he was trained when doing MLM. To do MLM, you must have positive energy.
Colorful Shenyu, a big man in the currency circle, went to the library one day when he was studying in the first year of study., see Bitcoin News. Then I skipped school and spent all day studying Bitcoin in my dormitory. The more I studied it, the more I liked it. I thought it was a new technology that would subvert the world. From then on, All in the blockchain, they were the first group of geek players, digging and selling coins by themselves. When he was 23 years old, he suddenly found that there were 100 million assets in his bank account. He was stupid, what should he do? ? How to spend 100 million? Go check the posts on Zhihu and read them one by one. In the end, you have so much money that you don’t know how to spend it, so you just go trash the place. You throw a party wherever you go and trash the place. After you spend the money, you’ll be fucking awesome. If it doesn't work, I have plenty of money. You can decide how much compensation I will pay.
Bitcoin is both a devil and an angel, occupying their lives. At the beginning, the price of Bitcoin was extremely low, ranging from a few dollars to dozens of dollars. It rose to hundreds of dollars. After a few thousand dollars, it dropped rapidly. It dropped so much that even my own mother no longer recognized her, and she couldn’t even recover the cost of mining. The mine can only be closed. After being lost and confused for a month, he came back again. This time he went to Sichuan, Xinjiang, and Tibet to mine in remote places with cheap electricity. In those places, traffic was almost paralyzed, and he often had to face sudden mudslides. .
Seven years is a lifetime. From 2011 to 2018, it is exactly a lifetime. In this life, the colorful fish has experienced many joys, angers, sorrows and joys that its peers cannot experience at all. It has experienced too many storms and waves in life. Now he is still a loyal fan of Bitcoin. He said that even if Bitcoin becomes zero one day, I will always collect some Bitcoins. It was Bitcoin that changed his life path. Otherwise, he would be an unknown program. ape.
The last story is the most tragic, and the director deliberately placed Liu Ke in the finale. Liu Ke, a sophomore, failed to speculate on Bitcoin and is now alone in a foreign country, struggling to survive by doing drug experiments for hospitals. The reporter asked him, do you know that conducting drug experiments in hospitals is a high-risk job? He said, of course he knows that the higher the price, the more dangerous it is, but if you were me, you would do the same.
Liu Ke is a handsome-looking boy. If he had not embarked on the road of blockchain, he would be playing basketball on the playground with a bunch of girls cheering for him. He wiped the sweat from his face and turned to give the girls a chic pose or a charming smile.
Although his parents are not rich people, they run a small business at home and give him 1,000 yuan a month for living expenses. If he could study and study peacefully, he should have been able to graduate successfully. But when the myth of blockchain wealth creation in 2017, the myth that he could double his money with 3,000 yuan in one night, made him lose control, so he took out loans on various platforms and used the loan money to invest. At that time, speculation Coins are like cash machines, no matter how you speculate, you can make money, and the word "risk" in his world disappears.
So he used 20 times leverageTo pry for greater wealth, I never dreamed that the wealth would not be pried away, and the nightmare was awakened. Creditors came one after another with all kinds of threats and inducements. He felt that he could no longer stay, so he thought of committing suicide. His parents had already persuaded him not to blindly speculate in coins, but he couldn't listen and hurt his parents' hearts again and again. Feeling very guilty and blaming himself, he did not commit suicide and had no choice but to flee to Cambodia. I don’t know when the days of running away like this will end.
After watching this video, I felt mentally uncomfortable for a long time. It can be said that there is no threshold for entering the blockchain world. Anyone can enter. You don’t need to understand finance or blockchain. You don’t need to know how to invest, even if you only have a few hundred yuan, you can enter. But now the industry is so unstandardized. Many people and many projects are just here to cheat, prepare a white paper, and after a wave of increases, the banker makes money and runs away. The unlucky ones are the leeks bought later. So far, the blockchain is a zero-sum game. At this stage, no real hematopoietic function has been born. So it is similar in nature to the rat warehouse. The people who get rich in the front are just making money from the leeks that enter later.
But investment is something we must face in this life. If we have never invested in this life, our understanding of human nature and society will never be complete. But investment only seems very simple. To invest well, you need to practice continuously.
㈦ What are the incidents related to Internet financial scams
With the in-depth application of the Internet by those born in the 80s and 90s, Internet investment is becoming more and more common. As the saying goes, when the forest grows big, there are all kinds of birds, and some illegal and deceptive Internet financial platforms use all kinds of tricks to attract investors. Today, as a researcher, Yijie investigated Zhalang and Du Niang and ranked the most deceptive and disgusting Internet financial scam in history so far, hoping to attract everyone's attention.
1. The ezubao incident illegally raised 50 billion yuan, setting off a wave of P2P exodus
Ezubao, known as the world’s largest Internet + financial leasing platform, shouldered the development of domestic P2P when it became popular. Under the banner, it has attracted nearly 50 billion in funds, involving nearly 800,000 investors, and has customers all over the country. It is so awesome that it dares to help the construction of the "Belt and Road". At the end of 2015, it was seized for setting up false bids and illegally raising funds. The case shocked the country. The funds of 800,000 investors have not yet been recovered. "The smelly meat spoils the soup." The eZubao incident set off a wave of P2P exodus.
2. The Airbus scam punctured the mutual gold bubble
One day in the future, you may be driving on the road, eating hot pot and singing, and suddenly a shadow floats from above your head. Don't be afraid, this is not a science fiction blockbuster, but something that may actually happen around us - the video of "The Mysterious Airbus Finally Has a Test Run". Just as people were blinded by the shining technological innovation of Air Pakistan Railway, the controversial Huaying Kailai Asset Management Co., Ltd. behind it surfaced. Huaying Kailai Asset Management Co., Ltd.As early as March this year, the company was listed as a company with abnormal operations by the Chaoyang Branch of the Beijing Administration for Industry and Commerce, but in the middle of the year, it used Airbus project financing to set a trap for investors.
3. The box office fraud of Ip Man 3 caused a crisis of trust in Internet crowdfunding
In March 2016, news of the box office fraud of "Ip Man 3" came to the film industry. At an interesting time, "Ip Man 3" Behind it is actually a financial product. The investor, Kuailu Group, has anticipated the box office from the beginning as a guarantee, and has issued a number of related funds. It has also done crowdfunding through the Suning Financial Crowdfunding Platform to provide financial support for "Ip Man 3". The product also conducts various derivative transactions, linking P2P, crowdfunding, stock markets, and funds. But when one loses, everyone loses. Box office fraud caused a chain effect, and Kuailu Group immediately fell into a redemption crisis. This incident has plunged the already controversial Internet crowdfunding into a current crisis.
4. The bottomless scam of buying for one yuan
“Use one yuan to realize a dream” You only need to spend one yuan, and you can get generous prizes, ranging from driving away a BMW, buying a mobile phone, to recharging a hundred yuan Card gas tickets, do you believe this is a good thing? A large number of Internet companies have one-dollar treasure hunt games that invite users to invest starting from one yuan, and then the lucky ones are drawn. Whoever is drawn will get the big prizes such as mobile phones and BMWs. A large number of users have become more and more addicted as they invest. Some people have invested four to five million without even knowing it, while others have gone bankrupt without hesitation.
Experts said: The business model of one-yuan purchase seems to be selling goods through the Internet platform, but in fact it is selling lottery opportunities under the banner of e-commerce, which is similar to online lottery sales. Last year, the state stopped online lottery sales. Therefore, one-yuan purchase is a business model with high legal risks, which will destroy transaction security and harm the legitimate rights and interests of consumers.
5. Cloud at Fingertips was investigated and punished, triggering a micro-business earthquake
What does Cloud at Fingertips do? It’s easy to think of cloud computing just by hearing the name. In fact, it is a micro-business distribution platform. The reputation is not small. According to the Daily Economic News, the Industrial and Commercial Bureau of Xianning City, Hubei Province issued an announcement stating that the suspected pyramid scheme case of "Cloud at Fingertips" has been closed. The parties were ordered to stop illegal activities, the illegal gains of more than 39.5 million yuan were confiscated, and a fine of 1.5 million yuan was imposed. A fine of 10,000 yuan was imposed. WeChat has also banned the public accounts related to "Cloud at Fingertips". What? Didn't it say that you can earn 100,000 a month, buy a Mercedes-Benz in 108 days, and buy a house in 6 months?! WeChat business has deep routines. Don’t believe it easily!
6. Campus loans force male college students to swallow pesticides and female college students to have forced sex
A freshman from the College of Continuing Education of a university in Changchun borrowed 10,000 yuan through a loan advertisement on campus. As a result, the loan was 6 days late and the loan company asked her to repay 42,000 yuan. The college student was forced to drink pesticide and commit suicide. Female college student Li Li borrowed a loan of 500 yuan with a weekly interest of 30%. The interest is compounded and she currently owes 55,000 yuan. Li Li couldn't afford the mortgage for the nude photos taken, so the lending company then instigated Li Li to sell her virginity and have a forced date to repay the loan.
7. Kunming Pan-Asia Empty Gloves
Kunming Pan-Asia Nonferrous Metals Exchange is atThe product "Rijinbao" sold online uses new investors' money to pay interest and profits to old investors, constantly luring "takeovers". "Rijinbao" has always maintained the illusion of prosperity, and as much as 43 billion yuan of funds has fallen into the trap. Kunming Pan-Asia demolished the east wall to make up for the west wall in the closed non-ferrous metals market. In the early stage, it continuously introduced liquidity to push up commodity prices, and then collapsed immediately when subsequent investment funds could not be sustained. More than 200,000 investors and more than 300 institutions are trapped in the quagmire just like those members of the rich club on Wall Street back then.
8.3M Mutual Financial Community Pyramid Scam
MMM Mutual Financial Community uses the guise of technological finance. The investment currencies can be RMB and virtual currencies (Bitcoin, Morgan Coin, Baichuan Coin), which makes it look like Unparalleled awesomeness. Don’t think that all those who are defrauded are the elderly. The victims of the MMM Mutual Aid Financial Community are mainly young people who are proficient in operating mobile network devices such as the Internet, online banking, and third-party payment APPs.
MMM is actually a pyramid scheme between acquaintances and a high rebate game. It does not have any actual products, does not connect to any industry, and does not generate any cash flow. It only develops offline through setting up recommendation awards and management awards, and attracts relatives and friends to join. This platform, which operates like a black box, has crashed and frozen many times before. Since there is no registered entity in the country and the servers are located abroad, the public security organs are unable to even intervene in the investigation.
9. Zhongjin’s 34 billion yuan redemption crisis
On April 6, 2016, the Shanghai police investigated and dealt with companies related to the “Zhongjin Group” suspected of illegal deposit absorption and fund-raising fraud. As of April 1, 2016, the first phase of Zhongjin Fund had raised a total of 5.26 billion yuan, exceeding the plan by raising 260 million yuan. Another data shows that as of February 10, 2016, the total investment of Zhongjin Partners has exceeded 34 billion yuan, involving more than 130,000 people.
10. Xinqi Assets 1.9 billion redemption crisis

According to reports, the case involved 5,000 investors and 1.9 billion yuan in funds. Investors reported that the police have opened a case to investigate.
㈧ What is blockchain? Blockchain is virtual currency
Let me tell you about blockchain in a simple way. There is no need to use advanced professional terms, because That's too difficult to understand. Let me give you an analogy to make sure you understand it at a glance.
Chinese mahjong can be understood as blockchain. If the four of you ABCD are going to play mahjong, who will say hello? If A greets, then A is the initiator of this block. A is responsible for finding the mahjong parlor. Organizer A can invite BCD, or B can invite C or C can invite D. It doesn't matter.
abcd gathered in a mahjong parlor,When you start playing mahjong, the process of shuffling the cards in the mahjong machine, drawing abcd cards, and playing cards can be understood as a mining stage similar to Bitcoin in the blockchain.
Everyone has different cards, which is equivalent to the algorithm in the block, but there is a goal, and they are all for the purpose of cheating. Among them, A cheated, and bcd said nothing. , everyone knows at a glance that A has won. This is called the consensus mechanism in the blockchain.
A is messed up. After A knocked down the mahjong, bcd all know how A got confused and remember it in their hearts. If A wins 10 yuan, both AbCD and A will know that A wins 10 yuan. , this is called distributed accounting in the blockchain.
Everyone who plays mahjong knows what mahjong arrangement can be used, and everyone also knows what cards can be doubled, so this can be understood as a smart contract in the blockchain.
Everyone knows the final winning card of A after A is knocked down. No one can tamper with this result because everyone is watching it. This can be understood as the immutability of the blockchain. sex.
After A announced that he was cheating, everyone did not go to another person, such as E, F, G... to verify. The same was true after B won... no regulatory agency can control it They all manage themselves. This is the decentralization in the blockchain.
By analogy, the four buddies abcd played mahjong for a day, and abcd recorded the winning and losing of each game, no matter what method they used, whether it was brain memory, video recording, or notes. Well, the more they fight, the more they can reflect the immutability, decentralization, distributed accounting, and consensus of the blockchain...
At this point, you Now you basically understand what blockchain is, isn’t it very simple?
The second question is that blockchain is not a virtual currency. Virtual currency is just a part of blockchain technology.
Many people think that virtual currency is the blockchain and Bitcoin is the blockchain. This is actually wrong. It’s just that the fame of Bitcoin has brought blockchain into the public eye.
Satoshi Nakamoto invented Bitcoin using blockchain technology, and he defined Bitcoin as a peer-to-peer electronic cash system. The term "electronic cash" indicates that what Satoshi Nakamoto wanted to invent was not Not just a payment system, but a monetary system with an independent monetary philosophy.
Today’s hotly-hyped virtual currencies, as well as mining, are resisted by many departments and countries. The fundamental purpose is not to waste resources, electricity, etc., but because people with blockchain technology Virtual currency has subverted traditional finance and can easily cause the collapse of traditional finance. I have talked about this in my previous Q&A, so I won’t go into details here.
It can be said that Satoshi Nakamoto and the Bitcoin he invented are the pioneers of the blockchain. It was Satoshi Nakamoto who brought blockchain technology into everyone’s field of vision. The application of blockchain technology alsoIt is very broad, including finance, medical care, service industry, big data security...
Let’s talk about this big data. As we all know, the impact of the recent Didi incident on big data security is quite large. If decentralization in blockchain technology is used, personal data can be obtained and saved through the blockchain. How can there be data leakage? In today's society, with the advancement of science and technology, as long as you use your mobile phone to connect to the Internet, you have no data security. Your personal information has already been leaked completely, so blockchain technology is inevitable for social progress. trend.
Let’s talk about blockchain. I hope you can learn something from it. You can also pay more attention to blockchain technology and improve your cognitive level. (Personally coded by hand)
Blockchain is an underlying technology that can issue virtual currency
Blockchain is a technology and a distributed decentralized Centralized technology, this technology can be applied to storage. Blockchain is not a virtual currency. Virtual currency is just a digital currency made using blockchain technology. Now, for example, the relationship between blockchain and digital currency is like, for example, if you build a dapp application mall on a certain chain, then you A token related to this mall can be issued.
The real connection between blockchain and virtual currencyWhat we are pursuing now is the application of blockchain technology. You develop a public chain and build many shopping malls, finance, defi, real estate, and tourism on this public chain. Such a dapp, this public chain has value, and then the tokens issued by this public chain have value, just like the current Ethereum, pi network
There are too many on the Internet now The so-called "blockchain digital currency", when we look at virtual currency, we look at what problems the public chain it is on can solve and what value it has, rather than blindly hype it. I think blockchain is the underlying technology. I think we only know The surface of blockchain.

Author: Leng Leng's point of view
Block Chain is a technology, and virtual currencies like Bitcoin are products of applications on the blockchain. There are many video explanations on my homepage.
In 2008, "Satoshi Nakamoto" first proposed the concept of blockchain in Bitcoin. Bitcoin is a peer-to-peer electronic cash system and is the earliest and most famous blockchain. Implement projects.
Generally speaking, a blockchain is an immutable ledger maintained by nodes in a distributed network. These nodes each maintain a copy of the ledger by executing transactions verified by the consensus protocol. The ledger exists in the form of blocks, and each block is connected to the previous block through a hash.
Blockchain is not equal to virtual currency
Blockchain is notIt is a virtual currency, and virtual currency is an application of blockchain technology. Let’s put it this way, blockchain is the Internet, and virtual currency is Sohu or Tencent. Blockchain is infrastructure and the infrastructure of future networks. It is China's national strategic technology. It has been pushed to the forefront, and the next step of informatization is based on blockchain.
Blockchain is a computer model of distributed data storage, point-to-point transmission, and consensus mechanism. In simple terms, blockchain is a decentralized database. How to use this technology? Is the value reflected? Under the consensus mechanism, a technical thing like blockchain is formed to give a specific token, which is BTC
Blockchain: Blockchain is a distributed ledger, through decentralization, Centrally maintain a reliable database in a trustless manner. Take Alipay transactions as an example. The traditional transaction method is that the buyer purchases goods on the Taobao platform, and then transfers the money for the goods to the intermediary platform Alipay. After the seller ships the goods and the buyer confirms receipt of the goods, the buyer notifies Alipay to transfer the goods. The money is transferred to the seller's account. However, the transaction model supported by blockchain technology is completely different. Buyers and sellers can trade directly without going through any intermediate platform for credit transactions. After the transaction, the system publishes the transaction information to the P2P network in the form of broadcast, and all received The node or host of the transaction information will record the transaction after confirming that the information is correct. Virtual currency: Virtual currency on the Internet, such as Bitcoin (BTC), Fuyuan Coin (FTC), Litecoin (LTC), etc. Bitcoin is an electronic currency generated by open source P2P software. Some people also paraphrase Bitcoin. "Bitcoin" is an online virtual currency. Mainly used for Internet financial investment.
Blockchain is a new type of Internet application technology, which uses emerging technologies such as distributed storage, cryptography, smart contracts, and consensus algorithms. It can be said to innovate existing Internet protocols. A new method of data transmission. At present, blockchain technology is constantly iterating
1. Blockchain 1.0, symbolizing the birth of Bitcoin; only with Bitcoin can the development of blockchain technology officially occur
2 , Blockchain 2.0, Ethereum decentralized application platform, Ethereum introduces the application of smart contracts, which represents the beginning of a new era of blockchain technology; now everyone can create projects on Ethereum, and in recent years Many good projects have been launched
3. Blockchain 3.0, DeFi opens the era of decentralized finance. DeFi projects use smart contract technology to realize various functions of traditional financial institutions, such as derivatives, Lending, trading, financial management, asset management, and insurance, etc. There are currently mixed reviews for DEFI, which will take time to verify
Although the blockchain originated from Bitcoin, just like the first computer when the Internet first appeared, Bitcoin is mainly used by miners. Mining rewards
Is the blockchain safe?
Hi, everyone, I am your quiz assistant - Zi Xiaochen. Recently, blockchain resistance has been widely concerned and discussed. But there are many people who don’t know much about its safety. So today we will talk about the security issues of blockchain.
First of all, would you like to hear an easy-to-understand metaphor? A friend of mine joked: "Blockchain is like a password lock. Without a password, no one can open it." Although this is simple and interesting, it makes a lot of sense. Since the blockchain uses distributed ledger technology, data is stored in a huge network, and the transmission between each node uses asymmetric encryption, the blockchain has extremely high security, and third-party attacks are very vulnerable. difficult.
Secondly, of course there are some security issues that need attention. For example, hacker attack methods such as "51% attack" can pose a threat to the blockchain. In addition, there are also security risks in virtual currency trading venues, such as Bitcoin exchanges, and you need to pay attention to precautions. Therefore, when choosing a blockchain platform or participating in virtual currency transactions, you need to know more and consider carefully to avoid losses.
In short, blockchain is an open technology, which has huge advantages in ensuring data security and preventing tampering. But we also need to be alert to potential security risks and choose reliable platforms and exchanges to participate in cryptocurrency investments.
I hope my answer can help you better understand the blockchain and its security issues. If you have any questions or want to share your experience, please feel free to message me privately! Finally, don’t forget to like, comment and forward, follow my articles, more content is waiting for you!
㈩ What does blockchain node mean?
Blockchain node means a smart device connected to the blockchain network. It can be called a node, but This node may play different roles depending on the characteristics of the device. This is a great feature of distributed networks, and the more nodes there are on the entire blockchain network, it means that the blockchain network is more widely distributed, more stable and more secure. Nodes include mobile phones, mining machines, servers, etc. Those who operate a node can be ordinary wallet users, miners, and mining pool users who collaborate with multiple people. ”
[Extended information]
A node is a server in a region. In the Internet area, all the running data of an enterprise is in one server, then this server is a node.
Just like what we use every day WeChat handles so many chat messages, transfers, etc. every day. The storage and operation of these data are all in Tencent's company's servers. So this server that processes data can be called a "node". Let's talk about blockchain In the world, everyone already knows that blockchain is a decentralized distributed database. It does not rely on any centralized server. It is composed of thousands of "small servers". As long as we download a blockchain Client, we become one of the thousands of "little servers".
In this way, if we want to play with the blockchain, we ourselves are equivalent to a node.
Nodes are also divided into light nodes and full nodes. A full node is a node that owns all the transaction data of the entire network, while a light node is a node that only owns transaction data related to itself. Moreover, the more and more nodes are distributed, the more decentralized the blockchain network will be, and the safer and more stable the network operation will be. For example, Lianxin has 16 million Lianxin users. This shows that there are also many Lianxin nodes. Now friends who want to play with blockchain can try Lianxin. LianXin is a good blockchain application.
The existence of nodes is a representation of the distributed nature of the blockchain and is also the charm of the blockchain.
Blockchain is a distributed system. There are many nodes in the system. You can simply understand these nodes as computers or servers connected through the Internet. Then, depending on the nature of the blockchain, the ways to become a node are also different. Of course, the definition of a node is also different. For public chains like Bitcoin, theoretically speaking, you only become a node when you download the complete blockchain and participate in transactions and mining.
However, in today's Bitcoin, miners, full nodes, lightweight nodes, and even ordinary users may all be called nodes in different contexts. But in any case, the Bitcoin system is not so much "the blockchain will automatically update when connected to the network", but rather that if you want to mine or trade (and you don't trust other people's verification results), you must update it. For the entire blockchain, this is not an automatic obligation, but a voluntary matter.
