Is the cloud blockchain of China Unicom reliable

1. The analysis of Chongqing jinwowo network is as follows:
each node on the blockchain can verify the integrity and authenticity of the account book to ensure that all transaction information is not tampered with, true and effective
every node on the blockchain keeps copies of all transaction information. When the number of data and participants on the blockchain is very large, the cost of modifying information will be very high. At least 51% of the computing power of the whole network is needed to modify information, and the modification cost may far exceed the expected revenue
when the information of some nodes is maliciously tampered with, other nodes on the blockchain will find the information that has not formed a "consensus" in a short time and maintain and update it.

2.

Blockchain is not deceiving, but deceiving people under the guise of blockchain. In fact, blockchain scam is to make use of people's ignorance of the technology, and then fraudsters rely on various and fancy means to set up scams. Many people only look at the surface when making investments, and finally fall into the trap of high profits

in the current society, more and more people are willing to take this risk to make investment in order to get rich returns, but not all of them can make profits. After all, where there are interests, there are many people waiting, and they will set traps for people to take the t

precautions

blockchain is a technology. In short, this technology is a new way of data management based on cryptography. Blockchain technology has broad application prospects because it has the advantages of decentralization, non tampering, tracing and so on. And issuing currency is a kind of behavior derived from blockchain technology. At present, the vast majority of blockchain applications which mainly focus on currency issuance and speculation are suspected of illegal fund-raising

blockchain technology is still in early development, and it is difficult to apply it. If you only rely on a white paper to claim that there is an application, it is a deception in itself

3. At present, there is no clear legal basis to prove the legitimacy of blockchain investment in China, and there is no law to prohibit the development of blockchain. However, blockchain investment also has great legal risks under the appearance of high income. Because blockchain is only a technology and method, there is no saying whether it is a hoax or not. However, different blockchain investments may be a hoax and more likely to involve crimes according to their forms
first of all, e to its lack of supervision, its circulation and trading forms are mostly similar to the issuance and listing of securities, and there is the behavior of setting up an exchange for trading. Its trading process and trading results are not transparent, and it is difficult to regulate when encountering problems. Moreover, its price formation mechanism is not transparent, and the trading price fluctuates greatly, which is easy to make investors suffer huge losses
secondly, it is not recognized by the central bank and can not be used as currency in China. Once it is subject to policy supervision, it is likely to encounter the risk that no one will take over the offer and the price will plummet, and the property law does not clearly protect the corresponding provisions of digital currency. Therefore, it is very dangerous to speculate on the blockchain, which is equivalent to streaking in the cold winter
finally, although blockchain is not illegal, it can not be ruled out that it is used by a small number of fraudsters and illegal fund raisers as a tool for crime and money laundering
therefore, it is recommended to carefully participate in blockchain investment to avoid irreparable losses.

4. The core feature of blockchain is decentralization and non tampering. As long as the data is linked, it will not be transferred by personal will. Therefore, it is credible. This year can be called the first year of blockchain. In the next few years, blockchain will be widely used, including financial and medical aspects. For more knowledge about blockchain, you can learn from Dr. coin community. Only you can understand it yourself, To know why it's credible.

5. What are the specific aspects? Blockchain is a technology. What are your classmates doing
blockchain projects, blockchain media, or what? Another possibility is digital currency. In any case, you'd better make a clear understanding of the blockchain before you decide. There are also a lot of people who cheat by using blockchain gimmicks. You have to distinguish them
you can learn about blockchain in some places, such as cryptography, finance and so on.

6. If the use of the characteristics of blockchain, such as decentralization, open sharing, authenticity, reliability and non tampering, is applied to proct traceability, it will undoubtedly be a great cause of benefiting the people and realizing China's integrity in a society where fake and shoddy procts are rampant. The emergence of traceability chain mall only sells authentic procts with traceability anti-counterfeiting technology as the core. By giving each proct a unique "China traceability chain. Com" traceability anti-counterfeiting certificate, the procts are added with the nature of traceability to protect the quality and safety of authentic procts and the legitimate rights and interests of consumers.

7. Don't waste electricity if it's dangerous

8. It's not a real digital currency. It's just a prop for swindlers. Don't participate in any digital currency. It's a money swindler. As the old saying goes, it's hard to persuade. I don't know if you are such a person!
