㈠ What to do if you find a fake blockchain platform in Quantum Chain China

If you find something is wrong, it is more correct to get out as soon as possible.
The core advantage of blockchain technology is decentralization. It can achieve decentralized credit 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, thus providing solutions to the problems of high cost, low efficiency and insecure data storage common in centralized institutions.
The application fields 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. , which has had a relatively large impact on the domain name industry.

1. Quantum is the smallest unit molecule, atom, photon, etc. that can show the characteristics of a certain substance or physical quantity. Microscopic particles are all the superposition and entanglement of quantum manifestations.

The quantum world follows the laws of quantum physics. The motion state, trajectory, and position of particles are probabilistic and have a superposition state.

The macroscopic world follows the laws of classical physics, and the motion state, trajectory, and position of particles are determined.

Quantum quantum superposition means that quantum can not only be in different states at the same time, but also be in a superposition of these states, that is, it can have multiple states at the same time.

2. Blockchain is a new application model of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. The focus is on the "consensus mechanism", which is a mathematical algorithm that establishes trust between different nodes in the blockchain system and obtains rights and interests. To put it bluntly, blockchain is a new distributed infrastructure and computing paradigm that can ensure the security of data transmission and access, and uses smart contracts composed of automated script codes to program and operate.

The purpose of the website is to transmit content and information.

The purpose of blockchain is to transmit assets and proof of transactions.

The smart contract system in the blockchain can make the transactions and witnesses of any kind of assets no longer rely on the government or intermediaries, greatly reducing the cost of establishing trust.

The essence of business is communicationYi, what kind of tools can reduce the overall cost of transactions from the aspects of time, space, credit, communication, etc. At present, it seems that blockchain can push the transactions of various assets to a higher level.

Decentralization is the design of an operating mechanism.

㈣ Tutorial for getting started with blockchain

However, there are very few simple and easy-to-understand introductory articles. What exactly blockchain is and what makes it special is rarely explained.
Next, I will try to write a best-understood blockchain tutorial. After all, it is not difficult. The core concept is very simple and can be explained clearly in a few sentences. I hope that after reading this article, you will not only understand the blockchain, but also understand what mining is, why mining is getting more and more difficult, and other issues.
It should be noted that I am not an expert in this area. Although I have been paying attention to it for a long time, my detailed understanding of blockchain started at the beginning of this year. You are welcome to correct any errors or inaccuracies in the article.
1. The essence of blockchain
What is blockchain? In a word, it is a special distributed database.
First of all, the main function of blockchain is to store information. Any information that needs to be saved can be written to the blockchain and read from it, so it is a database.
Secondly, anyone can set up a server, join the blockchain network, and become a node. In the world of blockchain, there is no central node. Every node is equal and stores the entire database. You can write/read data to any node, because all nodes will eventually be synchronized to ensure that the blockchain is consistent.
2. The biggest features of blockchain
Distributed databases are not a new invention, and there have been such products on the market for a long time. However, blockchain has a revolutionary feature.
Blockchain has no administrator, it is completely centerless. Other databases have administrators, but blockchain does not. If one wanted to add auditing to the blockchain, it would not be possible because it is designed to prevent the emergence of a central authority.
It is precisely because it is unmanageable that blockchain can be uncontrollable. Otherwise, once big companies and large groups control the management, they will control the entire platform, and other users will have to take orders from them.
However, without an administrator, everyone can write data into it. How can we ensure that the data is trustworthy? What if it is modified by a bad person? Please read on, this is the wonderful thing about blockchain place.
3. Block
Blockchain is composed of blocks. Blocks are much like database records. Every time data is written, a block is created.
Each block contains two parts.
Block header (Head): records the characteristic value of the current block
Body: actual data
The block header contains multiple feature values ​​of the current block.
Generation time
Hash of the actual data (i.e. block body)
Hash of the previous block
...
Here, you need to understand what a hash is , which is necessary to understand blockchain.
The so-called hashing means that the computer can calculate a characteristic value of the same length for any content. The hash length of the blockchain is 256 bits, which means that no matter what the original content is, a 256-bit binary number will be calculated in the end. And it can be guaranteed that as long as the original content is different, the corresponding hash must be different.
For example, the hash of the string 123 is (hexadecimal), which is 256 bits when converted to binary, and only 123 can get this hash. (Theoretically, it is possible for other strings to get this hash, but the probability is extremely low and can be approximated as impossible.)
Therefore, there are two important inferences.
Corollary 1: The hash of each block is different, and the block can be identified by the hash.
Corollary 2: If the content of the block changes, its hash will definitely change.
4. The non-modifiable nature of Hash
Blocks and hashes have a one-to-one correspondence, and the hash of each block is calculated based on the block header (Head). That is to say, the characteristic values ​​​​of the block header are connected together in order to form a very long string, and then the hash is calculated on this string.
Hash = SHA256 (block header)
The above is the calculation formula of block hash. SHA256 is the hash algorithm of the blockchain. Note that this formula only contains the block header and not the block body. In other words, the hash is uniquely determined by the block header.
As mentioned before, the block header contains a lot of content, including the hash of the current block body. , and the hash of the previous block. This means that if the content of the current block body changes, or the hash of the previous block changes, it will definitely cause the hash of the current block to change.
This point has great significance for blockchain. If someone modifies a block, the hash of the block changes. In order for subsequent blocks to still be connected to it (because the next block contains the hash of the previous block), the person must modify all subsequent blocks in sequence, otherwise the modified block will be removed from the blockchain . Due to the reasons mentioned later, hash calculation is very time-consuming, and it is almost impossible to modify multiple blocks in a short period of time, unless someone controls more than 51% of the computing power of the entire network.
It is through this linkage mechanism that the blockchain ensures its own reliability. Once the data is written, it cannot be tampered with. This is just like history, what happened happened, and it can’t be changed from now on.
Each block is connected to the previous block, which is where the name blockchain comes from.
5. Mining
Since synchronization between nodes must be ensured, the adding speed of new blocks cannot be too fast.. Just imagine, you have just synchronized a block and are preparing to generate the next block based on it, but at this time, another node generates a new block, and you have to give up half of the calculations and synchronize again. Because each block can only be followed by one block, you can only generate the next block after the latest block. So, you have no choice but to sync as soon as you hear the signal.
So, the inventor of the blockchain, Satoshi Nakamoto (this is a pseudonym, and his true identity is still unknown) deliberately made it difficult to add new blocks. His design is that on average, the entire network can generate a new block every 10 minutes, which is only six per hour.
This output speed is not achieved through commands, but by deliberately setting up massive calculations. In other words, only through an extremely large amount of calculations can the effective hash of the current block be obtained and the new block added to the blockchain. Because the amount of calculation is too large, it cannot be done quickly.
This process is called mining, because the difficulty of calculating a valid hash is like finding a grain of sand that meets the conditions among the sand in the world. The machine that calculates hashes is called a mining machine, and the person who operates the mining machine is called a miner.
6. Difficulty coefficient
After reading this, you may have a question. People say that mining is difficult, but isn’t mining just about using a computer to calculate a hash? This is the strength of computers. How could it be? It becomes very difficult, why can’t it be calculated?
It turns out that not just any hash can be used, only hashes that meet the conditions will be accepted by the blockchain. This condition is particularly harsh, causing most hashes to fail to meet the requirements and must be recalculated.
It turns out that the block header contains a difficulty coefficient (difficulty), which determines the difficulty of calculating the hash. For example, the difficulty coefficient of the 100,000th block is 14484.16236122.
The blockchain protocol stipulates that the target value (target) can be obtained by dividing the difficulty coefficient by a constant. Obviously, the greater the difficulty coefficient, the smaller the target value.
The validity of the hash is closely related to the target value. Only hashes smaller than the target value are valid, otherwise the hash is invalid and must be recalculated. Since the target value is very small, the chance that the hash is smaller than this value is extremely slim, and it may be calculated 1 billion times before it is considered a hit. This is the fundamental reason why mining is so slow.
As mentioned earlier, the hash of the current block is uniquely determined by the block header. If the hash of the same block needs to be calculated repeatedly, it means that the block header must keep changing, otherwise it is impossible to calculate different hashes. All feature values ​​in the block header are fixed. In order to make the block header change, Satoshi Nakamoto deliberately added a random item called Nonce.
Nonce is a random value. The role of the miner is actually to guess the value of Nonce so that the hash of the block header can be smaller than the target value so that it can be written to the blockchain. Nonce is very difficult to guess. At present, we can only use trial and error one by one through exhaustive methods. According to the agreement, Nonce isA 32-bit binary value, which can reach a maximum of 2.147 billion. The Nonce value of the 100,000th block is 274148111. It can be understood that the miner started from 0 and calculated 274 million times before obtaining a valid Nonce value so that the calculated hash can meet the conditions.
If you are lucky, you may find Nonce in a while. If you are unlucky, you may have calculated it 2.147 billion times without finding the Nonce, that is, it is impossible to calculate a hash that meets the conditions for the current block body. At this time, the protocol allows miners to change the block body and start a new calculation.
7. Dynamic adjustment of difficulty coefficient
As mentioned in the previous section, mining is random, and there is no guarantee that a block will be produced in exactly ten minutes. Sometimes it can be calculated in one minute, and sometimes it may take several hours. No result. Overall, with the improvement of hardware equipment and the increase in the number of mining machines, the computing speed will definitely become faster and faster.
In order to keep the output rate constant at ten minutes, Satoshi Nakamoto also designed a dynamic adjustment mechanism for the difficulty coefficient. He stipulated that the difficulty factor should be adjusted every two weeks (2016 blocks). If the average block generation speed in these two weeks is 9 minutes, it means that it is 10% faster than the legal speed, so the next difficulty factor will be increased by 10%; if the average block generation speed is 11 minutes, it means It is 10% slower than the legal speed, so the difficulty factor of the next step must be lowered by 10%.
The difficulty coefficient is adjusted higher and higher (the target value is getting smaller and smaller), which makes mining more and more difficult.
8. Forks of the blockchain
Even if the blockchain is reliable, there is still an unresolved problem: if two people write data to the blockchain at the same time, that is to say, two people write data to the blockchain at the same time. Blocks join because they are connected to the previous block, forming a fork. Which block should be adopted at this time?
The current rule is that new nodes always adopt the longest blockchain. If there is a fork in the blockchain, it will look at which branch is behind the fork to reach 6 new blocks first (called six confirmations). Based on a block calculation of 10 minutes, it can be confirmed in one hour.
Since the generation speed of new blocks is determined by computing power, this rule means that the branch with the most computing power is the authentic blockchain.
9. Summary
Blockchain, as an unmanaged distributed database, has been running for 8 years since 2009 without major problems. This proves it works.
However, in order to ensure the reliability of data, blockchain also has its own price. The first is efficiency. You have to wait at least ten minutes to write data to the blockchain. All nodes synchronize the data, which requires more time. The second is energy consumption. The generation of blocks requires miners to perform countless meaningless calculations. This is Very energy consuming.
Therefore, the applicable scenarios of blockchain are actually very limited.
There is no governing authority trusted by all members
The data written does not require real-time use
MiningThe benefits can make up for the cost
If the above conditions cannot be met, then the traditional database is a better solution.
Currently, the largest application scenario (and possibly the only application scenario) of blockchain is the cryptocurrency represented by Bitcoin.

㈤ Quantum computing, artificial intelligence and blockchain

Quantum computing, artificial intelligence and blockchain
In the next 5 to 10 years, it will be a new era in the world. It is a critical period for a round of scientific and technological revolution and industrial transformation to go from being ready to burst out. With the rapid development of a new round of global technological revolution, disruptive technological innovations are surging, the most eye-catching of which include quantum computing, artificial intelligence and blockchain. Are there any connections between these disruptive technologies and traditional Chinese culture? How does it relate to basic science (e.g. mathematics, physics)? How to objectively understand these cutting-edge technologies? This special issue publishes a report by Zhang Shousheng, an American theoretical physicist and foreign academician of the Chinese Academy of Sciences, who won the International Science and Technology Cooperation Award of the People's Republic of China in January 2018.
Currently, quantum computing, artificial intelligence and blockchain are the three most important basic technologies in the entire information technology industry. In the future, if information technology is to truly develop by leaps and bounds, we must pay attention to basic science, which requires both physics and mathematics, because physics and mathematics are closely related to the information technology revolution.

The discovery of “angel particles” has changed the dilemma of quantum computer research and development
Before talking about quantum computing, let’s first talk about the scientific discovery story related to “angel particles”. Many interesting modern sciences It is found that they are all related to changes in philosophical concepts, including those deep-rooted ancient philosophical concepts of the Chinese nation. For example, it seems that the world has always been a world of positive and negative opposites. If there are positive numbers, there must be negative numbers. If there are yin, there must be yang. There is goodness. There must be evil. This opposing world view is also present in the physical world of elementary particles.
There was a very great theoretical physicist in history, Dirac, who combined Einstein's special theory of relativity and quantum mechanics Unified, in the process of unification, he did a very simple mathematical operation and opened a root sign. When opening the root sign, there will always be two solutions, positive and negative. Most people may only care about the "positive solution" and not care about the "positive solution". "Negative solution". Dirac explained the "negative solution" as that all particles must have antiparticles, and predicted that all particles must have antiparticles.
In 1928, no antiparticles were discovered in the physics world. Everyone raised great doubts about him, saying that his equation was definitely wrong. He insisted that his equation was correct. Five years later, he was very lucky. Sure enough, physicists found the inverse reaction of electrons in the rays of cosmic radiation. Particles are positrons, named Dirac seas.
Since then, elementary particle physics has found protons and antiprotons, neutrons and antineutrons, and they have been applied. For example, positrons are used in the medical field It has been widely used. There is a medical test called PET, which uses positrons and negative electrons to form images. To measureFor Alzheimer's disease, the best way is to do PET.
Today, Chinese people are very concerned about scientific development. What is the biggest driving force for scientific development? I think it's curiosity about life. Theoretical physicists in history, such as Newton, discovered gravity when an apple fell under an apple tree and inspired him. When Einstein was riding in an elevator, he felt that the up and down movements of the elevator were very similar to the effects of gravity, thus creating the great theory of general relativity.
In addition, the development of science should not be superstitious about authority. After Dirac became a very famous theoretical physicist, scientists firmly believed that if there are particles in the world, there must be antiparticles. But another great theoretical physicist, Majorana, out of curiosity, asked whether there are some particles in the world that do not have antiparticles? He invented the Majorana equation, which wonderfully describes a particle that has no antiparticle, or that is itself its own antiparticle.
Later, the entire physics community was looking for the two coveted particles. One particle was called the "God Particle", which was found in an accelerator in Europe in 2012. The physicist Higgs who predicted it won the Nobel Prize. , and the other one is "Majorana fermion".
I work in theoretical physics, and the job of a theoretical physicist is generally to make predictions for experimental physicists to test. In 2010, my experimental group predicted that Majorana fermions could be found in a combined device. But we still need to find a signal that proves the existence of such a particle.
One day I thought that the Majorana particle had only one side and no opposite, so in a sense it was half the size of a normal particle. Our theory group made a bold prediction: Since Majorana particles are different from ordinary particles, in a sense, they are only half of ordinary particles. Therefore, its conductivity will be different. Usually the conductivity of particles is an integer multiple of 0, 1, 2, and 3, which will inevitably lead to a conductivity step that is a half-integer multiple. We predict it will have a step of 0.5 or 1/2. Later, our theoretical group worked closely with the experimental group and made experimental observations. Indeed, at 0.5, you can see that it is the original pattern of the experiment. A step appeared at 0.5, proving that Majorana The existence of fermions. We named it "Angel Particle" and everyone liked the name very much.
What is the relationship between “angel particles” and the development of information technology?
Currently computers have been divided into two categories, classical computers and quantum computers. Some problems are easy to solve by classical computers, such as multiplying two large numbers. Classic computers can calculate very quickly. But see if a number can be divided into the product of two other numbers. For example, 15 can be written as 3 times 5. If the number is relatively small, you can also calculate it yourself. But if you are given a very large number, it would take a long time for a classic computer to calculate whether the number is the product of two numbers, because the algorithm it uses is an exhaustive method, which divides all numbers that may be divided into one. Only by dividing them one by one can we finally be sureTo determine whether this is the product of two numbers, classical computers are very slow to calculate.
Classical computers can only use exhaustive methods to finally calculate an answer. But the quantum world is a very magical world, a parallel world. For example, in a famous experiment, if I release a particle, such as a photon, it has two holes, either on the left or on the right. But there is an authentic parallelism in the quantum world. A basic particle passes through two holes at the same time at a certain moment. If it is either left or right, the image is not the displayed image.
The quantum world itself is parallel. If you use the quantum world to do calculations, you can calculate in seconds and calculate all possibilities at once, because the quantum world has its original parallelism, which is the most basic concept of quantum computing. But it is very difficult to actually build this quantum computer. For example, the most basic unit of a classical computer is the bit, which means that information is either 0 or 1. All information can be expressed with 0 or 1. This is classical Computer concept. But in the quantum world, a particle passes through the left hole and the right hole at the same time, and is in a certain state of superposition. A qubit cannot tell whether it is 0 or 1. It is in a state of superposition of 0 and 1. Let’s listen to an analogy: Schrödinger’s cat is in a superposition of dead and alive. This is a very wonderful phenomenon. But because of this basic phenomenon, it means that a quantum bit itself is unstable. If you look around, you will know that it is either on the left, or on the right, or 0, or 1, whatever. A piece of noise will cause great interference to the qubit.
Recently, quantum computers have become something of special concern to famous companies around the world and the United States. Google, Microsoft, IBM, and Intel are all making investments, but they cannot fundamentally solve this problem because a qubit is very unstable. One day we will be told that we have made 50 qubits, but the key question is how many useful bits are there. If there is only one useful bit, 10, 20 or even 40 or 50 qubits are often needed under the framework of this kind of quantum computing. Having the wrong bits to serve it makes quantum computing difficult to actually implement.
But the discovery of angel particles has fundamentally changed the dilemma of quantum computer research and development. This is a process from quantitative change to qualitative change. The qubit itself has the ability to correct errors, which is how I usually split a qubit into two angel particles. Normal particles have two sides, but angel particles have only one side, so angel particles are usually only half of a particle. So usually one qubit can use two angel particles to store it. Once two particles are used to store it, they are in a distant place and they are entangled with each other. In the classical world, noises are not entangled with each other. In this way, noise cannot be used to destroy the quanta stored by angel particles, so this is a revolutionary change.
So, I gave a speech at the American Physical Society not long ago, saying that angel particles are an exciting discovery and can be used for quantum computing.The machine has as many bits as it has, and does not need to add error correction bits. It has its own error correction function, which will play a rapid role in the development of quantum computers.

The day robots can make scientific discoveries, that day intelligent machines will surpass humans
As a basic concept, artificial intelligence has been proposed in the 1960s. Today's artificial intelligence can develop by leaps and bounds, mainly due to the summary of many new technologies. According to the iteration of Moore's Law, it can double every 18 months. If you use quantum computing, it will not just double Moore's Law every 18 months, but completely change from quantitative to qualitative change. Human computing power has continued to grow over the years. The birth of the Internet and the Internet of Things has generated a large amount of data. Intelligent algorithms are changing by leaps and bounds. Big data can help machines learn. However, the basis of artificial intelligence is all kinds of data. No matter how good the algorithm is, no matter how powerful the computer is, it cannot become artificial intelligence without data.
Artificial intelligence, although I can see that it is advancing by leaps and bounds, I feel that it is still in its very early stages. Why do you say this? To make a simple analogy, for example, we once saw birds flying, and people also wanted to fly very much. However, in the early days, learning to fly was just simple bionics. Tie wings on human arms. This is simple bionics, but the real state of flying is Since humans have understood the first principle of flight - aerodynamics, and with the physical principles and mathematical equations, they can design the best aircraft. Today's aircraft fly high, fast and well, but they are not like birds. , this is a very core point.
Most of the current artificial intelligence is simply imitating human neurons, but what we should think more about is that there is an opportunity for a major breakthrough in basic science. We must truly understand the basic principles of wisdom and intelligence. , Only in this way can artificial intelligence truly make fundamental changes.
What kind of basis can we use to truly measure artificial intelligence’s ability to meet human standards? Some people may have heard of the Turing test. The Turing test means that a person talks to a machine, but it is not known whether the other person is a person or a machine. During the entire conversation, if you spend a day and can’t feel it at all, it means that the robot seems to have reached the level of a human. Although Turing was a great computer scientist, I do not agree with this method of judgment. Many human emotions are not rational emotions. It may not be easy for a rational machine to learn from the brain of an irrational human.
So I would like to propose a new judgment method. When will intelligent robots truly have intelligence that surpasses humans? I think the greatest thing about human beings is that we can make scientific discoveries. One day robots can really make scientific discoveries, that day machines will surpass humans.
Recently I wrote an article on artificial intelligence, which will be published in the Journal of the American Academy of Sciences. It will be mentioned in the article that the greatest scientific discoveries of mankind include relativity, quantum mechanics, etc., which are the greatest in chemistry. The discovery was the discovery of the periodic table of elements. Can intelligent machines automatically discover without any guidance?Periodic table of elements? Can it help humans discover new drugs? Can machine learning be used to discover new materials? These are the criteria for judging the level of artificial intelligence.

To realize the coexistence and development of blockchain and artificial intelligence, they will be the most valuable
In today’s world, individuals will generate a lot of data, personal genetic data, medical data, Educational data, behavioral data, etc. are particularly needed for the development of artificial intelligence. A lot of data is held in central institutions and has not achieved true decentralization. The emergence of blockchain can create a decentralized data market.
I describe the entire concept of blockchain in one sentence, called "In Math we trust". This concept is based on mathematics. The most basic thing in the entire blockchain and the entire information technology field is basic mathematics, which can protect personal privacy in the data market and make reasonable statistical calculations. For example, there is a very magical calculation method called zero-knowledge proof, which can prove to you that my data is very valuable, but it does not tell you where the truly private data is.
With blockchain, the data market can make society more equitable. The biggest injustice in modern society is that people tend to discriminate against some minorities. But what is most needed in the machine learning process is the data owned by the minority. If the accuracy of machine learning reaches 90% today, and increases from 90% to 99%, what it needs is not the data that has been learned, but different data from before. It is often a small amount of data that is most valuable for machine learning. Once our data is built on the basis of blockchain, coupled with these wonderful mathematical algorithms, we will be able to have a healthy data market. In this world, the concept of blockchain and artificial intelligence coexisting with each other will be the most valuable.
As for the entire blockchain, the public’s understanding of it is not the most fundamental first-principles understanding. In terms of the most basic physics principles, reaching a consensus is like everyone agreeing on the same "ledger". It is equivalent to that in physics, magnets are originally messy, but in the ferromagnetic state they all point in the same direction. of.
Achieving consensus also occurs in the natural world. This phenomenon is called entropy reduction. Reaching a consensus, if everyone is moving in the same direction, the entropy of this state is far smaller than the entropy of chaos. Reaching this consensus is very difficult because entropy is always increasing.
Achieving a consensus system on the blockchain uses an algorithm, which requires energy consumption. This thing sounds unreasonable, why does the account consume energy, but from the second theorem of physics, this is a very reasonable thing, because reaching a consensus itself is a decrease in entropy, but the entropy of the entire world must increase. Therefore, while reaching a consensus, other entropy must be eliminated. This non-centralized mechanism is very similar to the natural world where magnets change from a chaotic state to an ordered ferromagnetic state. It is inevitable to pay a price for consuming energy.trend.
So the ideal information world is that in the future everyone will have all their own data and it will be stored in a completely decentralized manner, so that hackers will not be able to hack everyone's data. Then using some encrypted algorithms on the blockchain can truly protect personal privacy and make good calculations, and things like the theft of many personal data in Facebook will not happen.
The problems we have to solve today in quantum computing, artificial intelligence, and blockchain technology are all problems for mankind. Chinese scientists will face great opportunities. In addition to doing a good job in applied technology, they should also have real Original basic scientific breakthroughs, such as the physical and mathematical principles introduced above, although these things sound relatively abstract, such as the principle of entropy increase, positrons and negative electrons. The wonder of the world lies in the fact that basic science can provide broad new development prospects for the entire information technology industry.

㈥ How to join the blockchain

1. Buy your own equipment for mining
Now someone has invented a "mining machine" specially used for mining. Ordinary individuals want to Participating in mining is also relatively simple. You only need to plug in the power supply and network cable to the mining machine to start running. However, mining also has risks. Bitcoin output is halved every four years. In addition to the costs of mining machines, electricity bills, maintenance, etc., there are also risks such as unstable calculations and power outages. Moreover, the operation of mining machines is very loud, which will affect rest at home. , you need to choose a "mining machine" with high computing power and low power consumption, and then find a basement or warehouse to mine. Generally speaking, the cost is very high. If you encounter a bear market in the currency industry, the miners will be the worst off.
2. Participate in currency speculation or currency hoarding
As the most successful project of blockchain technology, virtual currency is truly an investment suitable for most investors. “Perhaps not everyone has the capital to buy and sell virtual currency itself; but to trade such as the virtual currency trend trading method launched by Jinsheng Options, the cost of US$5 is still something that many ordinary investors can easily do, and no matter whether it goes up or down, The feature of making money can increase the possibility of investors making profits several times." said an investor with 3 years of experience in virtual currency investment.
3. Do blockchain self-media
In the early days of the blockchain market, many people did not understand what blockchain was and wanted to participate, which inevitably gave birth to a blockchain knowledge payment market. So far, there are not many media working on blockchain, so there is still a broad demographic dividend. You can write articles, record videos, broadcast voices, and even make live broadcasts. The possibilities are endless: investment experiences, project analysis, industry news, welfare selections, and knowledge popularization.
4.ICO
ICO (abbreviation of Initial Coin Offering), initial coin offering, is essentially blockchain crowdfunding and a way for blockchain startups to raise funds from the public. . Some friends may want to participate in ICO projects, thinking that the returns are higher than currency speculation, just like listing original stocks is better than buying and selling stocks in the secondary market. However, there are many deceptive ICOs in the market at present, and many white papersThey are too lazy to write, so they raise funds aggressively, mostly air coins and pyramid scheme coins. ICO is extremely risky and is classified as illegal in China. It is not recommended for ordinary investors to participate.
5.IFO
IFO (Initial Fork Offerings) is the first fork currency issuance. They generate new tokens by forking the Bitcoin blockchain, claiming that they can achieve functions superior to Bitcoin, which is currently a way to attract attention.
Investing in blockchain is the same as high-risk investments such as stocks, with higher costs and risks, and the pressure you need to bear is unmatched by ordinary investments. Therefore, everyone must think carefully before entering the currency circle.
