宣传区块链的目的是什么,宣传区块链的目的和意义

宣传区块链的目的是将信息和财富的流动更加快捷、安全、透明，以提升用户的体验和满足用户的需求。为了实现这一目标，我们拓展了3个相关关键词：去中心化、加密和智能合约。

去中心化是区块链的核心理念，它消除了传统金融体系中的中心化机构，使得用户可以自主进行财务活动，比如转账、收款等，而不需要第三方机构的介入。由于没有中心化机构，它可以有效防止数据泄露和恶意操作，让用户的资金安全得到保障。

加密是区块链的另一个重要特征，它可以保证所有的数据和资金的安全性。区块链采用非对称加密技术，使用公钥和私钥来保护用户的信息，确保数据不被篡改和滥用。此外，每笔交易都需要经过数字签名，以确保交易的安全性和真实性。

智能合约是区块链技术的另一个重要应用，它可以自动执行合同，从而减少了人为操作的错误和时间浪费。智能合约是一种由计算机代码编写的程序，它可以自动完成合同中的条款，并在满足一定条件时自动执行。智能合约可以有效提高交易的效率和安全性，减少了纠纷的发生率。

以上就是宣传区块链的目的和意义拓展的3个相关关键词：去中心化、加密和智能合约的介绍。区块链技术的出现，改变了传统金融体系，它可以有效提高交易的效率和安全性，让用户的资金安全得到保障。

❶ Is blockchain a disguised pyramid scheme?

Blockchain is a new technology and is not a disguised pyramid scheme. It is just claimed as "blockchain" by many pyramid schemes. In fact, It does not have any technology, it is just a pyramid scheme in the name of "blockchain". The country has issued multiple announcements to crack down on this type of pyramid scheme. The following is Xinhuanet's report on blockchain MLM:

Blockchain is not equivalent to virtual currency, and there are also security risks. Behind the popularity, there are exaggerated publicity campaigns with "ulterior motives". Only by removing the flashiness can the blockchain return to its true application value.

Invest 80,000 yuan and it will become 800,000 yuan in three months? Shenzhen police uncovered a huge fund-raising fraud case. Under the guise of blockchain concepts and 10 times earnings, thousands of investors have fallen into it, with the amount involved reaching 307 million yuan. Under the "mysterious veil" of the blockchain, criminals have taken advantage of the opportunity to use their tricks, and the blockchain has become a "signature" for economic crimes such as fraud and pyramid schemes.

Why has the blockchain been repeatedly “misused” by illegal activities such as pyramid schemes and fraud? Apart from being “unclear”, what is the “function” of blockchain technology itself? Since the beginning of this year, with the intensification of supervision and the cooling of the trend of currency speculation, new opportunities have been brought to the development of blockchain. How is the implementation of blockchain commercial "applications" now? Reporters from "Lookout" News Weekly recently conducted an investigation into this.

When the three-month "fund release period" promised by the trading platform expired and the staff started "kicking" people in the QQ group, Tang Haiyan, who lives in Bao'an District, Shenzhen, realized that she might have been cheated. .

Previously, Tang Haiyan invested 80,000 yuan to buy a virtual currency called "Puyin Coin" under the introduction of a classmate. "The other party said that this currency is the most advanced blockchain technology at the moment, with Tibetan tea as collateral, and he also showed me a 'technical white paper'. I didn't understand blockchain, so I didn't read it carefully."

Although he doesn’t know much about blockchain or virtual currencies, Tang Haiyan is full of expectations for the high investment returns. She told reporters that the company that issued the "Common Silver Coin" would regularly split the virtual currency at a ratio of 1:10, which means that each split would increase the value of the "Common Silver Coin" in the hands of investors by 10 times. . As long as it is split once, the 80,000 yuan she invested is equivalent to buying "common silver coins" worth 800,000 yuan, and she can get huge profits by selling them on the trading platform.

According to the rules of the trading platform, the "common silver coins" just purchased cannot be traded immediately. They must be frozen on the platform for three months before the "release period" can begin. However, when three months passed, Tang Haiyan not only failed to double her assets, but also the 80,000 yuan frozen on the platform could no longer be used for transactions.

“Other investors began to question the authenticity of this investment in the QQ group. As a result, the company staff kicked these investors out one by one. I felt bad.” She said.

Facts also proved Tang Haiyan’s intuition. At the end of March 2018, Shenzhen police detected a special caseA large fund-raising fraud case, the amount of defrauded funds was as high as 307 million yuan. In this case, the Shenzhen Puyin Blockchain Group Co., Ltd. involved in the case used the "blockchain + Tibetan Tea" model to issue virtual currency and defraud public deposits. Tang Haiyan was one of thousands of victims. .

An investigation by the Shenzhen police found that the company claimed that investors could trade "common silver coins" on the virtual trading platform "Jubi.com" to earn the price difference

. In fact, the change in its buying and selling price was caused by the company using investors' investment funds to perform behind-the-scenes operations, and once raised the price of "common silver coins" from 0.5 yuan to 10 yuan, allowing investors to taste some sweetness. When a large number of investors entered the market, the company continued to cash out by maliciously manipulating the price trend of "Common Silver Coins", which eventually resulted in the "Common Silver Coins" in the hands of investors being worthless.

Since 2018, engaging in fraud and pyramid schemes under the banner of blockchain has become a commonly used "routine" in new criminal methods. In April 2018, Jinan police busted a pyramid scheme gang under the guise of "western development", "national poverty alleviation", "original stocks", "blockchain" and "e-commerce", arrested more than ten main suspects, and froze the funds involved in the case There were more than 100 accounts, and more than 300 million yuan of funds involved were seized.

Jinan police said that Huileyi e-commerce company designed fake virtual disks on the Internet and released so-called "treasure coins" and "precious coins" on the grounds that the country is vigorously developing the big data industry. and other virtual currencies.

They first use the gift as a guise to give a certain amount of virtual currency to newly joined MLM personnel, with the price of each coin being tens of yuan, and then through artificial manipulation, the virtual currency will rise to more than 100 yuan or even hundreds of yuan. Yuan, attracting people who do not know the truth to join, and finally "cut leeks" through the cyclical fluctuations of the so-called "devaluation" of virtual currencies, repeated over and over again, and ultimately achieve the purpose of seeking illegal benefits.

In Xi'an, the local police also successfully cracked a huge online pyramid scheme under the banner of blockchain. According to the police, the criminal suspect Zheng paid a high salary to organize network platform administrators Zhang, Li and other 9 people. Since March 28, 2018, he has used collective pyramid schemes and online pyramid schemes as means to sell coins at a price of 3 yuan each. Sell ​​virtual "Datang Coins" on the "Consumption Era" online platform and control the appreciation rate;

At the same time, hold promotion meetings in multiple cities at home and abroad to attract members, and set up There are 28 levels of agents in charge. In just 18 days, the gang has developed more than 13,000 registered members. It has been found that the case involves 31 provinces, municipalities, and autonomous regions across the country, and the funds involved are as high as 86 million yuan.

The "Tencent 2017 MLM Situation Awareness White Paper" released by Tencent Security Joint Laboratory stated that in recent times, various overseas capital disks, virtual currencies, ICO (blockchain project initial public offering of tokens) Financing) projects emerge in an endless stream, which hide many risks such as illegal issuance, false projects, cross-border money laundering, fraud, pyramid schemes, etc., causing a large amount of funds to flow overseas. Once it collapses,Investors often have no way to complain, lose money, or lose contact, and their losses are difficult to recover. For example, Baichuan Coin, Mark Coin, Beta Coin, Dark Coin, etc.

Reporters from "Lookout" News Weekly conducted interviews in Guangdong, Shandong, Shanghai and other places and learned that most people know that the concept of blockchain is very popular, but they are "uninformed" about the specific functions of blockchain. There are different opinions: some people think it is used for "investment and financial management" and "buying and selling currency", while others think it is "a major invention of the same magnitude as the steam engine". Some entrepreneurs are gearing up to seize this "once-in-a-lifetime opportunity to get rich."

Many people in the industry said that it is precisely because people have many misunderstandings about blockchain that criminals have the opportunity to fish in troubled waters and mislead investors.

First, blockchain is not equal to virtual currency. As of the end of last year, the number of domestic ICO participants and total transaction volume had doubled. A large number of digital currency exchanges have fled overseas, and the agency investment model has involved more ordinary people in high-risk investments.

Many industry self-media and famous speakers have formed interest alliances with issuers, digital exchanges, etc. to endorse the "Air Coin" project platform and create public opinion. In December last year, the People's Bank of China and nine other departments characterized ICOs as "suspected of illegal fund-raising, financial fraud, pyramid schemes and other illegal and criminal activities."

During the interview, many people told our reporter that the existence of tokens has built a set of equity mechanisms for the development of blockchain technology. This mechanism is indispensable for stimulating the prosperity of blockchain applications. of. "Market practice in the past five years has proven that blockchain applications without equity mechanisms are like computers without Internet connectivity and a market economy without currency. The application scenarios and development speed are greatly reduced." said an investor in Shanghai. .

In fact, tokens represented by Bitcoin are only one of the earliest products to verify blockchain technology. There is no equivalence between the two, and the existence of tokens has already affected the blockchain technology. The development of the chain has obvious negative effects.

Xiao Wei, chief engineer of the Internet Blockchain, told this reporter that the myth of ICO getting rich has shaken the R&D efforts of blockchain technology talents, and the myth of getting rich through coin speculation, which can easily return hundreds of times, is testing the blockchain industry. The patience of chain technology R&D talents. "Many of the 'comrades' in the circle who used to do blockchain technology research and development together have switched to issuing coins, and now there are very few who can continue to do technology research and development and application."

Beijing Internet Finance Industry Xu Zewei, secretary of the party committee of the association, said that under the background of China’s ban on ICOs, many domestic start-up companies promoting blockchain applications are “selling sheep’s heads to dogs”, packaging originally worthless tokens through conceptual packaging to attract money for financing. “ICO has polluted the good atmosphere for innovation and entrepreneurship and created a speculative product. Many young people don’t think about starting a business, but they are thinking about issuing coins. This gives everyone the illusion of getting rich overnight.”

< p>At present, more and more people in the industry are beginning to think about whether the development of blockchain must rely on the issuance of tokens to achieve incentives. Guo Dagang, secretary-general of the Beijing Internet Finance Industry Association, told this reporter that the so-calledThe incentive mechanism is just a theoretical basis for the project side to issue tokens for itself. Huo Xuewen, director of the Beijing Municipal Financial Affairs Bureau, also believes that if the blockchain does not get rid of the currency issuance dilemma, it will never find a legal implementation mechanism.

Secondly, the blockchain is not omnipotent and has security risks. Blockchain is generally considered to be able to achieve three functions:

First, the data stored on the blockchain cannot be tampered with or forged, and the data has high credibility and credibility; second, The entire transaction process is traceable, enabling accurate tracking of responsibilities; third, smart contracts embedded in the blockchain can be automatically executed based on the contract, thereby improving work efficiency and reducing the risk of default. The industry generally believes that blockchain has broad application prospects in finance, logistics, trade and other fields.

In fact, blockchain is not omnipotent, and its functions also have many limitations. It is generally believed that based on its cryptographic characteristics, if you want to tamper or forge on the blockchain, you theoretically need to control more than 51% of the nodes to achieve it. When there are enough nodes in the blockchain, this trust creation mechanism with widespread public participation will be difficult to tamper with.

However, in reality, digital currency exchanges are frequently attacked or even stolen. On June 20, 2018, South Korea's Bithumb exchange announced on its official website that the exchange was attacked by hackers and cryptocurrency worth 35 billion won, or approximately US$32 million, was stolen.

Ji Xinhua, known as China's first generation "hacker", said that the blockchain will continue to face attacks, and the process of uploading data to the chain is prone to information leakage. Some people in the industry are also worried that once the super computing power of quantum computing is realized, it will also have a direct impact on the blockchain.

Zhao Yao, a special researcher at the Institute of Finance of the Chinese Academy of Social Sciences, told this reporter that as early as 2013, the academic community confirmed that the blockchain is not perfect and there are many "cheating" strategies. As long as there are sufficient economic incentives, attacks that control more than 51% of the nodes do not only exist in theory.

Zeng Guang, secretary-general of the Shenzhen Internet Finance Association, said that blockchain technology itself is not irreplaceable or subversive. "Some criminals exaggerate the role of blockchain to illustrate that blockchain has huge investment value, which deserves the vigilance of investors."

Thirdly, the popularity of blockchain is not the same. Not entirely true. Data shows that from the end of 2017 to the beginning of 2018, more than 300 self-media companies mainly focused on ICO projects appeared, which became an abnormal phenomenon worth noting.

“Most of these self-media have received financial support from exchange leaders and investors in the currency circle. It is difficult to guarantee the objective independence of their reports. Most of them advocate ICO and currency speculation, and excessively promote digital currencies. Prospects, creating convenience for the spread of public opinion for illegal fund-raising of problematic projects." Xu Zewei said that some blockchain self-media investors are themselves ICO project investors, and their profit model is to charge soft article fees and project promotion fees, becoming a token issuance public opinion helpers, and some media have developed into agency investment agencies.Profit from it.

(1) Extended reading on the purpose of promoting blockchain:

On August 24, 2018, the China Banking and Insurance Regulatory Commission website issued a risk warning to remind the general public Prevent illegal fund-raising in the name of "virtual currency" and "blockchain".

The original text is as follows:

Risk reminders on preventing illegal fund-raising in the name of "virtual currency" and "blockchain"

China Banking and Insurance Regulatory Commission, Central Cyberspace Affairs Commission , the Ministry of Public Security, the People's Bank of China, and the State Administration for Market Regulation remind:

Recently, some criminals have issued so-called "virtual currencies" and "virtual assets" under the banner of "financial innovation" and "blockchain". "Digital assets" and other methods to absorb funds and infringe on the legitimate rights and interests of the public. Such activities are not really based on blockchain technology, but are actually hyping up the blockchain concept to conduct illegal fund-raising, pyramid schemes, and fraud. They mainly have the following characteristics:

1. Networking and cross-borderization are obvious. Relying on the Internet and chat tools for transactions, and using online payment tools to receive and disburse funds, risks have a wide scope and spread quickly. Some criminals rent overseas servers to build websites, essentially carry out activities for domestic residents, and remotely control illegal activities.

Some individuals claim in chat tool groups that they have obtained investment quotas for high-quality overseas blockchain projects and can invest on their behalf, which is most likely a fraudulent activity. Most of the funds for these illegal activities flow overseas, making supervision and tracking very difficult.

2. Strong deception, temptation and concealment. They use hot concepts to create hype and fabricate numerous "high-level" theories. Some even use celebrity V's "platform" propaganda, and use airdrops of "candy" as temptations, claiming that "currency values ​​only rise but not fall" and "the investment cycle is short. "High returns, low risks", which is highly deceptive.

In actual operation, criminals illegally make huge profits by manipulating the price trend of so-called virtual currencies behind the scenes and setting profit and withdrawal thresholds. In addition, some criminals also issue tokens in innovative forms such as ICO, IFO, and IEO, or conduct virtual currency speculation in the form of IMO under the banner of the sharing economy, which is highly concealed and deceptive.

3. There are various illegal risks. Through publicity, criminals use "static returns" (profits from currency appreciation) and "dynamic returns" (profits from offline development) as bait to attract the public to invest funds, and induce investors and development personnel to join in, constantly expanding the capital pool. , with characteristics of illegal fund-raising, pyramid schemes, fraud and other illegal activities.

Such activities use "financial innovation" as a gimmick, but are essentially a Ponzi scheme of "borrowing new and repaying old", making it difficult to maintain long-term capital operations. The general public is requested to view the blockchain rationally, do not blindly believe in promises made by the public, establish correct currency concepts and investment concepts, and effectively improve risk awareness; they can actively report to relevant departments any clues about illegal crimes discovered.

❷ What are the functions and characteristics of blockchain

1. Any node can create transactions, after a period of confirmation, it can be reasonably confirmed whether the transaction is valid, and the blockchain can effectively prevent the occurrence of double-spending problems.
2. The cost of trying to rewrite or modify transaction records is very high.
3. Blockchain implements two types of records: transactions and blocks. Transactions are the actual data stored on the blockchain, while blocks are records confirming when and in what order certain transactions became part of the blockchain database. Transactions are created by participants using the system in the normal course (in the case of cryptocurrencies, a transaction is created by Bob sending tokens to Alice), while blocks are created by what we call Units of miners are responsible for creation.

❸ Why is the blockchain so popular?

Why is the blockchain so popular
In early February this year, the Weibo account "Sina Finance" posted this post: A young man from Hangzhou went on a blind date online, but no girl talked to him for more than a month. Later, he added a "blockchain engineer" label to himself and received more than 200 private messages in a few days.
As the most popular industry nowadays, news about recruiting blockchain talents with a million-dollar annual salary makes headlines from time to time. The blockchain industry is becoming a new blue ocean in the job market.
Blockchain talent is in short supply
Blockchain technology is a product of Bitcoin. In 2008, the founder of Bitcoin, who calls himself Satoshi Nakamoto, proposed the concept of "blockchain". By 2015, this underlying technology of Bitcoin has become the new favorite in the global financial and technology industries, and the demand for relevant talents has also increased. Then it increased dramatically.
U.S. Bloomberg quoted data from the professional social networking site "LinkedIn" as saying that job postings related to blockchain, cryptocurrency and Bitcoin increased at least four times in 2017; on CoinDesk, one of the largest employment websites in the United States , 15 of the 18 most popular industry positions are related to cryptocurrency. Data from the website shows that the number of blockchain technology jobs posted in the United States in 2017 increased by 207% compared with the same period in 2016, and by 631% compared with the same period in 2015. On China's mainstream Internet recruitment apps, there are thousands of recruitment information in the blockchain industry.
Corresponding to the rapid expansion of scale, there is a serious shortage of professional talents. Since blockchain has just become popular for two or three years, schools and educational institutions have not caught up, and relevant courses are rare. In addition, blockchain is an interdisciplinary industry that places equal emphasis on knowledge and experience, which poses greater challenges to talent training. challenges.
There are two main types of companies hungry for blockchain talent: well-established technology companies and ambitious startups. Bloomberg quoted Griffith Hill, chief recruiter of a blockchain talent team, as saying that the technology software industry and the financial services industry are the two fields with the largest number of blockchain jobs posted on LinkedIn.
Almost all Internet companies are recruiting blockchain front-end architects and developersBlockchain development engineers, including eBay, ESPN and Uber in the United States, Tencent, Xiaomi, Xunlei, Lenovo, JD.com in China... According to the report released by the 2017 Fintech100 company in March 2018, among the top ten blockchain recruiters in the world in 2017 , half of which are Chinese companies, with Ant Financial, Zhongan Technology and Qudian taking the top three spots. Internet finance, computer software, and enterprise services have the strongest demand, accounting for more than 50% of the total.
Traditional companies are also vigorously recruiting blockchain talents to improve their own efficiency or better serve customers. Data from CoinDesk shows that large consulting firms such as Deloitte and IBM are the largest employers in the industry. Deloitte has hired more than 800 people in the blockchain field. IBM is also actively looking for relevant talents. In 2017, the company's number of employees in the blockchain field increased from 400 to 1,600, and it has launched more than 400 blockchain projects, and there are still more than 150 blockchain-related job vacancies.
The geographical distribution of blockchain jobs is closely related to economic level. The American "Forbes" magazine website announced the top 15 blockchain employment cities in the United States in February 2018. New York ranked first, with a job gap of 1,316; followed by San Francisco, Boston, Chicago, etc. Outside the United States, there are 423 vacancies in London, 357 in Singapore, 149 in Toronto and 97 in Sydney. In China, according to statistics from Huxiu.com in February 2018, "Beijing, Shenzhen, Hangzhou and Guangzhou" account for more than 80% of blockchain-related positions in China, of which Beijing ranks first with 44.2%.
The threshold for core positions is high
Blockchain talents are not necessarily “coders”. Of the 800 newly recruited blockchain talents by Deloitte, half are developers or architects, and the other half are business analysts, strategy and technology consultants, accountants, etc. Specifically, recruitment in the blockchain industry mainly includes technology, project, operation, and logistics categories.
Of course, technical positions are the most urgently needed. According to statistics from Huxiu.com in February 2018, R&D positions accounted for 49.34%, followed by operations, marketing, and researchers. Technicians need to be able to build applications on top of the core platform and, ideally, independently develop cryptocurrency platforms such as Bitcoin and Ethereum. To this end, they need to master at least one or more languages ​​such as C, C++, C#, Java, Go, etc., have a deep understanding of the underlying technology of the blockchain, understand various mainstream consensus algorithms, and also understand economic principles, monetary theory, etc. . If you want to do blockchain development, the threshold is really not low.
In comparison, the threshold for the other three types of talents is lower and they do not need to have too much industry background. They only require a clear understanding of blockchain knowledge based on their own expertise. If you know some financial knowledge and can perform data analysis, it will be the icing on the cake. From an educational point of view, a master's degree is a necessary stepping stone.
For the blockchain industry, compound talents are undoubtedly the most popular. therefore, talents who master C++ and Go, and are proficient in cryptography and distributed computing are the most popular at the moment. Most companies will form teams of people with different expertise to make up for their respective shortcomings and gradually learn and grow during the project implementation process.
The blockchain industry is developing extremely rapidly, and one needs to have very strong curiosity and the ability to learn quickly to keep up with the pace of blockchain development. Therefore, youth is the biggest bargaining chip. Talents who have been in the industry for 1 to 3 years are the most sought-after at the moment. This is because this period of time allows a person to accumulate enough experience in blockchain development without being worth so much that employers will be discouraged.
Of course, top talent is always scarce. People who can independently develop cryptocurrency platforms such as Bitcoin and Ethereum are being chased around the world. Some people think that there will be no more than 2,000 such "big names", and some even think that there will be no more than 200 people. The difficulty of this kind of work is equivalent to writing code from scratch to create an operating system that can compete with Android or iOS. What most technicians can do is equivalent to developing apps on the operating system.
Some people make a million dollars a year, and some people make a bottom dollar
Can blockchain practitioners really make "a million dollars a year"? This is indeed true according to data from mainstream recruitment websites. For example, Suning.com offers a monthly salary of 50,000 to 100,000 yuan to "senior blockchain developer", and Keda shares also offers a monthly salary of 85,000 to 100,000 yuan to a "blockchain R&D director." However, Alibaba Health's monthly salary for "blockchain technology experts" is 15,000 to 30,000 yuan, and the "blockchain technology evaluation" position at China Academy of Information and Communications Technology is 10,000 to 20,000 yuan.
It can be seen that salaries in the blockchain industry are also polarized, and the differences are huge. The annual salary of core technical personnel generally starts at 150,000 yuan, and senior "big bulls" can indeed earn more than one million yuan per year, and also enjoy equity or option awards; the income of product, media or administrative personnel is not much different from that of other industries. According to Bloomberg, the market The salary level of marketing positions is at the bottom of the entire blockchain industry, with an average annual salary of only US$63,000, compared with RMB60,000 to RMB120,000 in China.
According to statistics from Huxiu.com, positions with a salary of 120,000 yuan/year account for about 18.6% of the total R&D positions, positions with a salary of 180,000 to 240,000 yuan/year account for about 36.2%, and the remaining 47.8% are distributed Within different salary ranges. Salaries vary greatly between regions. The average annual income of blockchain practitioners in places such as Shanghai and Beijing is about 200,000 yuan, while in Guangdong, Zhejiang, Fujian and other places it is about 160,000 yuan.
Be careful when facing the trend
The current explosive growth of the blockchain industry is mainly due to the intensive influx of capital, which is inevitably reminiscent of the Internet bubble from 1998 to 2000: after the capital carnival, most companies Finally left sadly. The main growth in blockchain jobs comes from the mushrooming of start-up companies. These companies are inevitably good and bad, and many of them use asymmetric information and over-package "empty-glove white wolves".
According to science and technology economic mediaAccording to a report by Titanium Media, there are currently many recruiting “routines” for domestic blockchain companies. Many companies use "financial freedom" to attract job seekers, promising to reward employees with stock options after financing is in place, and even allow employees to join as "partners." But the actual situation may not be like this - no salary will be paid in the first three months of joining, the actual office area is only 15 square meters, the team only has two or three people, and there are no system regulations and constraints. As for the work content, it is to "plan two to three product promotion plans every day." The "product" is actually the company's own "digital currency". The purpose is to attract retail investors and institutions to subscribe as much as possible. When the number of buyers reaches a certain number Then "encircling" capital institutions to invest is quite a scam.
Titanium Media stated that there are currently countless blockchain companies stationed in incubators in various places, and most of them have not yet received financing, and some even lack corresponding capital flow support; employees are often fresh graduates and those with higher qualifications. The shallow ones are the main ones, and they only talk about "ideals" but not about money; some companies "scam the money and then run away." "These blockchain companies may look prosperous, but in fact they may be very poor, just waiting to use white papers to cut leeks." Faced with the full screen on the recruitment app, "The company's CEO and partners personally lead the team, the team is top-notch, and the atmosphere is good. With slogans such as "over 100 million users, sufficient funds, unlimited development space, option incentives, five insurances and one housing fund, no check-in...", job seekers should remain cautious and calm.
The current “high salary” image of blockchain is partly due to the explosive growth of the industry and the shortage of talents. Against the backdrop of a slowdown in the overall economic situation, it is understandable to seize rare development opportunities and pursue higher salaries, but the risks of plunging into emerging fields that are unfamiliar to most people cannot be ignored. As the industry further develops and matures, and relevant talent training mechanisms are gradually improved, more professionals will enter the industry in the future. If you don't pay attention to improving your own strength and blindly follow the trend, then "annual salary of one million" may be just a myth under the bubble.

❹ "Blockchain" has become a hot word recently. Why is "blockchain" so popular?

When it comes to blockchain, we have to mention Bitcoin. currency, and we have to mention its mysterious founder-Satoshi Nakamoto.

It is no exaggeration to say that the blockchain was invented and created by Satoshi Nakamoto, but Satoshi Nakamoto’s original purpose was not to make the blockchain The popularity of blockchain, but he hopes that the decentralized virtual currency he founded, Bitcoin, can develop. Therefore, Satoshi Nakamoto may have expected the popularity of Bitcoin, but the popularity of blockchain may have exceeded Nakamoto’s expectations. Cong's surprise.

Therefore, blockchain will affect all aspects of society in the future, and many industries or our current lifestyle may be subverted as a result.
