1. There are several people around me who have been deceived by blockchain

2. What is the chaos of blockchain craze

According to reports, as blockchain has transformed from a cold and obscure professional term into a hotly discussed "hot" trend, many merchants with a keen sense of smell are trying their best to seize the opportunity and use various fancy " "Taking advantage of hot spots" takes the opportunity to make money. Behind the overwhelming pursuit of resources and capital from all parties, there may be a tangle of excitement and anxiety: seize the spotlight or pop the bubble?

Why is it so popular? It is reported that the "Traffic Ore Box" is an entry-level "mining artifact", which can be said to be mined using the sharing economy. It mainly collects and utilizes idle broadband resources and rewards users through the blockchain digital asset LLT of traffic ore. The digital asset LLT can be exchanged for shopping cards and recharged for electricity bills, phone bills, Internet bills, etc., to obtain certain real benefits.

Behind the heated discussion among the people, it is difficult to hide the entanglements and worries of all walks of life about the future fate of blockchain. "On the one hand, everyone realizes that blockchain has a promising future as a new technology and wants to seize the spotlight. However, because it is a new thing, there are also many uncertainties and there is a certain risk of bubbles." Industry insiders said frankly that in Under the background that blockchain technology is not yet mature, for some institutions that are "running into the game", how to cross the river by feeling the stones while being careful about "bad money driving out good money" deserves further thought and attention.

3. What are the existing problems of blockchain technology

1. Performance issues

Volume issues

Blockchain pair Data backup requirements pose storage space challenges. Blockchain requires that after a transaction is completed, it is broadcast to the entire network, and every node in the system must back up data.

Take Bitcoin as an example. The block data since the creation block has exceeded 60GB, and the amount of blockchain data is still increasing. This will bring problems to the operation of the Bitcoin Core client. A big challenge.

Processing speed issues

The Bitcoin blockchain currently processes a maximum of 6.67 transactions per second, and a confirmation time is about 10 minutes, which can easily cause congestion delays for a large number of transactions, which may Applications with small multiple transactions and highly time-sensitive transactions will be restricted.

Although there are some methods to overcome it, methods to comprehensively solve transaction efficiency still need to be discovered.

Energy consumption is too high

Thirdly, the computing power in the mining process does not produce additional actual social value, and also wastes a large amount of electronic resources. With the increasing popularity of currency, blockchain has gradually become a capital-intensive industry with high energy consumption.

2. Centralization problem

Inequality of nodes

First, in theory, every node in the distributed network should be treated equally ,However, in order to obtain rewards for mining, each node may increase its computing power to compete for hardware, resulting in node inequality and destroying the randomness of blockchain accounting rights.

Industrialized and large-scale mining has given rise to mining pools

Theoretically, if the mining pools collude to control more than 51% of the computing power for system supply, a dual Although the costs of payment far exceed the benefits in the actual process, the possibility of collusive supply cannot be denied.

3. Privacy and security issues

Private keys are easily stolen

First, the current blockchain uses an asymmetric key mechanism. It has high security, but the private key is stored locally and can be easily stolen by hackers.

The transparency of blockchain data can easily lead to privacy leaks

Every participant in the public chain can obtain a complete data backup, and the entire system is open and transparent. The currency protects privacy by isolating the connection between the transaction address and the holder’s true identity.

When the blockchain needs to carry more businesses, how nodes verify information and execute commands requires more consideration.

4. Upgrade and incentive issues

The number of participating nodes in the public chain is huge

Whether it is upgrading or fixing errors, the system cannot be shut down and centralized. , it may be necessary to consider relaxing the issue of decentralization.

There is a competitive game between each node

Requires the improvement of incentive compatibility mechanism, how to enable self-interested nodes in the decentralized system to spontaneously carry out block data verification And accounting work, and designing a reasonable penalty function to suppress irrational competition is another challenge faced by the blockchain.

4. What are the risks of blockchain transactions

When conducting blockchain transactions, the three most catastrophic risks that need attention are (ordered from high to low severity) : Personal risk, platform risk and policy risk The biggest risk: Personal risk If personal risks are not well controlled, you may encounter: 1. Passwords and private keys are stolen, and all digital assets in wallets and trading platforms are lost (unable to be retrieved) ) 2. Your information will be sold back and forth by the underground black industry, with almost no privacy. 3. If you use the same or similar password in other places (banks, securities trading platforms), assets in other places will also be stolen. How to avoid this? Personal risk: Increase password strength, do not reuse passwords, do not send passwords online...Do not run naked on your computer (without installing security and anti-virus software), do not go to messy websites ("pornographic, gambling and drug" websites are the hardest hit areas for Trojan viruses) All Need

5. What challenges does the blockchain currently face?

What challenges does the blockchain currently face
At this stage, the main application projects in the blockchain field It is divided into two aspects: first, new business models that are more compatible with blockchain technology;Such as cross-border payment, supply chain finance, product traceability and other scenarios; the second is the application of reform based on existing centralized business, that is, using the economic incentive mechanism of Token.
With the development of technology, the number of application projects in this field is expanding rapidly. Many people believe that 2018 will be the year when blockchain will truly integrate with the real economy and explode. However, blockchain technology is still in its early development stage and faces challenges including the regulatory environment, lack of talent, and technical awareness.

From a technical perspective, applying blockchain technology to actual industry scenarios requires solving issues such as transaction speed, data consensus, and node maintenance. The current Bitcoin network can only process seven transactions per second, and the leading Hyperledger technology can only reach the level of 200 to 300 transactions; compared with the centralized system that can process tens of thousands of transactions per second, there is still a gap. Large distances. In addition, the current lack of relevant incentive mechanisms in the field makes it difficult for participating nodes to operate in an orderly manner. From a regulatory perspective, although most countries are actively embracing blockchain technology, there are currently no relatively complete regulatory regulations and industry standards. Inappropriate regulatory measures may hinder the innovative development of such emerging technologies.
Affected by various factors such as the underlying technology that needs to be further matured, the lack of smart contract public chain platforms, the lack of ecological compatibility of various Tokens, and unclear government supervision; at this stage, the implementation of blockchain application projects is relatively slow. It shows that the quality of projects varies greatly. For this reason, analysts said that compared with general-purpose blockchains, what will achieve breakthroughs in the short term may be focused blockchains for specific scenarios and applications.

6. Why are there so many “scams” ​​in the currency circle that relies on blockchain technology?

Behind any investment with an unusually high return rate, there may be a hidden meaning of “you” He wants his interest, but he wants your principal" type of scam.

On July 4, 2018, a recording of Li Xiaolai, known as "China's richest man in Bitcoin", was exposed, causing an earthquake in the currency circle. In the nearly hour-long recording, Li Xiaolai made sharp comments on many big players in the currency circle, and also gave "step-by-step" instructions on how to cut off the leeks of retail investors.

Although my country has rectified and banned ICOs according to law in September last year, it is not uncommon for project parties to avoid legal supervision through foreign registration and underground ICO models. This requires regulatory authorities to increase their efforts in governance, establish sound industry standards, and promote the good development of the blockchain industry.

For investors, on the one hand, they must keep their eyes open and not blindly follow the temptation of so-called "Internet celebrities". If you really believe Li Xiaolai’s remarks denying value investing and advocating speculation, then you are playing into his trap and will eventually become a leek that can be harvested by others. On the other hand, you need to invest rationally. Behind any investment with an abnormally high return rate, there may be a scam like "you want his interest, but he wants your principal".

7. Blockchain wallet scams.

What I want to share with you today is a blockchain wallet scam.

At present, various blockchain projects are flying all over the market. Whichever industry is popular will have which chain and which currency!

These blockchain projects are financial investment projects and are different from the blockchain technology advocated in my country’s key development directions. It is a fund package that uses blockchain technology as a bait for packaging, speculation, hype, and money trapping.

Blockchain is a decentralized super ledger that cannot be copied, falsified, or changed. A technology like this is still used in many practical scenarios in banks, insurance, and large companies such as Alibaba and Tencent.

Many so-called blockchain projects do not have any service targets, so just build a blockchain. Who will they serve? Where will they be applied? It is nothing more than creating a concept. Raise the currency price to make money.

I think there are two types of people who understand human nature best in the world, one is psychologists, and the other is liars. In the eyes of these behind-the-scenes bosses and liars, the new technology of blockchain, mixed with virtual currency, is an excellent story framework that can be used to make money with a little processing.

Those mainstream virtual currencies do not have extremely short cycles and collapse at the speed of light like domestic MLM coins or altcoins. Instead, they fall, rise, rise, rise and fall in a long cycle, just like the stock market. . There is a saying in the currency circle that it is harder to keep money than to be a widow

Therefore, those who have the fantasy of getting rich all day long hold in the hands of these seeds that are said to be able to get rich, but they watch them fall every day. It goes up again and again, up and down again. Isn’t it like sitting on pins and needles? How many ordinary people can sit still?

At this time, the blockchain wallet came into being. “As long as you put the money on hand The virtual currency is deposited in my so-and-so wallet, the capital is guaranteed and the income is guaranteed, and it is quite comfortable to get rich while lying down."

There was once a very popular wallet product that claimed to guarantee principal and provide monthly interest rates as high as 10%-30%. The operation is even simpler than P2P. First deposit the virtual currency into the app account, then turn on the "smart dog" brick-moving mode, and then open the wallet every day and watch the assets rise. That is to say, you can make money while lying down.

Moreover, as long as you use the compound interest investment model and recruit people, the annual return is conservatively estimated to be 700%! If you recruit people to level 10, the rate of return will be 1400%! All fools know that it can Get rich!

Haha, this is the brilliance of a trader. One product can clearly arrange the psychology of leeks!

The wallet, to put it nicely, is called "quantitative trading bricks" ", actually, it’s just a disguised fund disk. The essence is fixed rebates. In fact, those traders in the past found that consumer rebates are not easy to use, so they started to package them. Seeing that the blockchain is hot now, they used mainstream coins to make an article. I packaged a wallet and said My wallet has high-frequency cash out and high-frequency trading functions. In the past, you used to use money to buy products, or you gave me money directly. You are worried. Now I don’t want money. You use the money to buy Bitcoins. Then put your Bitcoins in my wallet, and I will give you interest every day of the month based on the amount of coins you put.

Well, Bitcoin is money, and you bought your coins with money. In the end, he may shut down the Internet and run away, then take all your coins and go to the transaction himself. All cashed out.

You want his interest, he wants your principal!

The blockchain wallet model is actually a model that uses fixed rebates to attract investors. The difference is that the deposit is virtual currency. The most typical blockchain wallet is the plus wallet.

For example, after you deposit Bitcoin, you will receive rebates every day. The source of the rebates claims to have smart arbitrage as an income. source, and then return you the platform currency, and then exchange the platform currency with a digital currency in the international market, and then go to Huobi.com to withdraw cash to obtain profits. When you withdraw cash, you will be charged a handling fee. For example, if you withdraw within 28 days, you will be charged a 5% handling fee. If you withdraw after 28 days, you will only be charged a 1% withdrawal handling fee.

It was officially launched on May 1, 2018, and the plus wallet trading platform was launched in October. It collapsed in June 2019. After running for more than a year, this disk package became one of South Korea’s Team operation is actually driven by the Chinese. Six traders have been arrested by the Chinese police. This project has 1 million members participating and the funds involved reach 20 billion yuan.

Judging from the running time, this product has a long existence cycle, which should be beyond the imagination of many people at the beginning. The reasons are:

First, it uses What you invest in is virtual currency, and what you withdraw is also virtual currency. For these mainstream currencies, Leeks have better illusions, thinking that there is still a lot of room for appreciation, and it will be more profitable to keep them. Since it is just a matter of putting it forward, why not continue to put it in the plus wallet to get the profits? To a certain extent, it delays the time of large-scale withdrawals.

Secondly, Plus Wallet spent a lot of money on publicity. One moment it sponsored some blockchain conference, the next it talked about developing new products and launching new systems, and the next it talked about going public. The purpose of this crazy campaign is to exchange time for space.

Let me introduce you to several routines of blockchain wallets in detail:

Point 1, the so-called arbitrage is impossible to support your subsequent rebate income.

Because the real income from moving bricks is not a stable income, and it will not be as substantial as he described.

Like the plus wallet, based on the rebate data before the crash, it needs 700 million yuan in rebates every day to continue operating, so this number is astronomical. Obviously there is no way to do smart arbitrage. If you think you can, then you have nothing to do with it. With such high skills in moving bricks, do you still need to rely on rewards to attract people? You can move it yourself, and there are big institutions rushing to invest, so there is nothing to do with you!

The second point is that the money returned by the platform to the people in front is mainly the funds coming in from behind, which is exactly the same as the characteristics of the fixed rebate plate.

If you want a promotion reward system with up to 10 levels, as well as super high rebates, you also have to pay high deposit interest. Therefore, soon the subsequent funds will not be able to keep up with the speed of rebates, and problems will arise in the capital chain. The platform will shut down and run away.

The third point is that the platform currency exchange channel for Bitcoin can be closed at any time. As for when to close, only the trader can decide, so you are faced with huge risks at any time.

Point 4: It is stipulated that you will be charged a 5% handling fee for withdrawals within 28 days, and you will only be charged a 1% handling fee for withdrawals after 28 days. This purpose is to allow you to extend the withdrawal time as much as possible , he can deposit more funds into the capital pool.

Originally, everyone entered the currency circle because it is a decentralized technology. You store the currency in a real wallet, and as long as you keep your private key, no one can take it away from you. assets.

As a result, you hand over decentralized assets to some centralized platforms far abroad.

Let’s analyze it from another angle

The private key is a 256-bit binary code, encoded into numbers and letters. Finally, it is mapped into words to facilitate memory, also called mnemonics.

Some wallets have different mnemonics. The mnemonic phrase for plus is a bunch of random characters. Some wallet mnemonics must be made in Chinese, etc.

In short, the core of the blockchain wallet is to allow you to deposit mainstream currencies into his wallet, and then return to you a lot of their platform coins. Your currency is money, and its currency can only be coins. If you recommend others to come here to deposit coins, you will also get promotion benefits. In fact, you can understand its essence if you think about it. It is the same as getting money back, but it is just using coins. Then I will tell you my capital flow. It’s safe, you don’t have to worry about crashing or running away, because I don’t touch the money, so who am I kidding? Coins are not money, right?

Do you want your mnemonic phrase to be different?Can I import it to another wallet? It’s definitely not possible. Only your wallet can be used. Doesn’t this become a completely centralized platform?

8. What are the scams of blockchain?

"Blockchain" is an important concept in the new era. It is essentially a centralized database and one of the digital currencies. The underlying technology of the class. According to our popular explanation, the "blockchain" can be regarded as a ledger, and each bill is a block. However, this ledger is centralized, and it can be said that no company or team has jurisdiction over it. "Blockchain" technology is a unique informatization that is centralized and cannot cross-change information. Now in daily life, this technology has been applied to a series of applications such as electronic invoices and payment codes.
In today's life, many people use this guise to commit fraud. Direct sales disks, capital disks, technology disks and other names are used to lure people to make money and then run away. As a result, many people have lost their funds and have nowhere to defend their rights. In the end, I can only say that "blockchain" is a lie. There is no right or wrong in technology, it’s the people who are wrong.
With the progress of the times and the progress of society, the initial application of any technology will be subject to various positive and negative doubts. However, with the relative application and maturity of technology, coupled with the improvement of technology, various aspects around people have formed. This application will continue to improve, and I believe that these doubts will slowly dissipate in the near future.
The following is a summary of some blockchain scams that are often around you!
Trap 1: Blockchain is about issuing coins to make money
Trap 2: Conducting virtual currency transactions, promising low investment and high returns
Trap 3: Decentralization can solve all problems
Trap 4: With the extension of the blockchain, you can make money with a mining machine
Trap 5: Transactions on WeChat and Alipay to buy and sell virtual currencies
In short, the methods of scammers are also advancing with the times. Through our "eyes of wisdom", we can improve and enhance our adaptability, discover and alert ourselves, and prevent being deceived. Investors must be wary of various deceptive methods that offer low investment and high returns.
