以上就是全球区块链乱象中的三个关键词——区块链技术、反洗钱和政府监管的介绍。区块链技术是一种分布式账本技术，可以有效地帮助反洗钱和政府监管，从而更好地保护金融市场的安全、稳定、公平和有序。

❶ The development of blockchain has been frustrated during the epidemic, and flashy blockchain pilots are falling out of favor

Under the new crown epidemic, blockchain suppliers and advocates are afraid of enterprises Frustration in blockchain implementation.

The adoption of blockchain is a relatively new area for business leaders. As the economy shrinks and IT budgets shrink, blockchain may be the first project to be axed.

While no sweeping changes have hit blockchain adoption, the landscape of the technology has certainly shifted.

Similar to the trends in data and software, the focus of blockchain implementation in the COVID-19 era has also shifted to areas where technology can provide the greatest value in the shortest time.

Eschewing flashy pilots without clear intent, leaders are targeting areas of higher value, with COVID-19 pressures further deepening the weaknesses of existing blockchain applications.

In the aftermath of the crisis, funding for blockchain pilots has slowed as bosses suspended forward-looking projects and spent funds on more urgent firefighting activities.

According to forecasts released by IDC in June, as global IT budgets shrink, global blockchain spending is expected to reach US$4.3 billion in 2020, a year-on-year increase of 57.7% from US$2.7 billion in 2019. . Despite this growth forecast, it is down 7.7% from IDC's last forecast.

Global blockchain budgets are currently forecast to reach $14.4 billion by 2023, a further reduction from the pre-COVID-19 estimate of nearly $16 billion.

The current actual impact on blockchain adoption has been low. One trend has been a decline in interest among large companies in pilots and proof-of-concepts without clear commercial returns.

When assessing the shift in blockchain adoption post-COVID-19, a crucial context is the instability of the economic environment.

When the first wave of lockdowns hit North America and Europe, almost all blockchain work was initially halted except for networks already in production.

Some large vendors and software integration companies have shifted their focus to enabling remote work, with people almost all working from home.

When considering blockchain implementation, enterprise technology leaders must always be wary of the hype from vendors and technology proponents and think carefully.

According to Gartner data, as of 2019, only 4% of organizations have blockchain projects and are running them on a large scale.

In the current environment, where IT leaders are under pressure to shrink budgets, any blockchain project that does not have a very clear reason for existing risks being shut down.

When companies evaluate the merits of blockchain pilots, clear benefit criteria include:

But for blockchain implementation, as an integral part of the platform, it can improve the supply chain and reduce costs.

Delivering these benefits has proven elusive for most businesses. According to Gartner, even those networks that exist today will need to be replaced as technology evolves to remain competitive, secure and avoid obsolescence.

As enterprises adapt to new operating environments, blockchain offers a way for enterprises to reduce the cost of reliable access to data between partners and reserve non-value-added costs.

To effectively pursue blockchain as part of their digital transformation journey, CIOs need to determine which aspects of their business and operating models can be automated to better serve customers.

Organizations should evaluate which combination of solutions can help achieve this outcome. In this case, blockchain can be connected with artificial intelligence or the Internet of Things. Instead of looking at blockchain as one thing that provides multiple capabilities, try to see the different capabilities of blockchain and try to integrate them into your business needs.

❷ Zhu Xiaohuang of CITIC Bank: Many blockchain companies are either fools or liars. How do you evaluate it?

I think what Mr. Zhu said is very reasonable. Blockchain Now that it has become a hot topic, those engaged in the Internet seem to be out of touch with the times if they don’t talk about blockchain. Today, the editor will give you some popular science: what exactly is blockchain? Why do we say that many blockchain companies are either stupid or have ulterior motives?

1. What exactly is blockchain?

When talking about blockchain, we have to mention Bitcoin. Blockchain is simply a distributed shared ledger and database. Its advantage is that it is decentralized and cannot be tampered with, because modifying one data cannot affect all records. The characteristics of openness, transparency and traceability are conducive to solving the current pain points and difficulties in many fields such as financial supervision, public welfare, and anti-counterfeiting.

To sum up, for us melon-eating people, just listen to blockchain. If you really want to invest money in the currency circle, 99% of it is Harvested as leeks. Netizens, do you agree with the editor's statement? Tell us your views and leave a message in the comment area for discussion.

❸ Some blockchain public accounts have been blocked. Is the deadline for blockchain media approaching?

Some blockchain public accounts have been blocked for allegedly publishing ICO and virtual currency transaction speculation information. Permanently blocked! This does not mean that the end of the blockchain media has arrived, but it shows that the government has begun to seriously manage the blockchain market! The current currency circle that relies on blockchain is really full of chaos and demons are dancing around. It’s really time for higher-level departments to take charge!

But manyOlder people have invested everything they have, tens of thousands, hundreds of thousands or even millions. Some even ask for loans or even sell their houses. If they really lose everything in the end, I am really worried about what these old people will do. Where to go!

I am Vanilla Pearl,

Psychological growth, spiritual improvement, we go together all the way!

❹ Why is blockchain not a “panacea” for all economic activities?

Recently, the most eye-catching thing that has appeared frequently in major public opinion media is undoubtedly the blockchain chain.

Third, blockchain data is completely open and transparent. If anti-anonymous identity screening technology is developed in the future, a user’s information can be seen through password cracking, and some key targets Location and identification are also possible, posing threats to data security and personal privacy.

Fourth, supervision is still on the way. Decentralization means that the main body is not clear, which also brings great difficulty to supervision; especially regulators under blockchain technology will face "a huge amount" data, it is difficult to regulate the transparency of information and achieve precise supervision. In addition, the vacancies and lag in the regulatory legal system have resulted in the lack of necessary institutional norms and legal protection for blockchain applications, increasing market risks.

Obviously, blockchain technology is not a "safe" that ensures the absolute security of the financial industry and other economic activities, nor is it a "panacea" that can serve all economic activities. Whether they are companies involved in the research and development and application of blockchain technology, or investors involved in investment in blockchain-related industrial projects, they should maintain a cautious and rational attitude.

❺ Current status and future development trends of blockchain

Blockchain has developed to 3.0, and application exploration is the current goal

According to IDC definition, blockchain It refers to a distributed ledger that records information and data. The ledger is stored between multiple participants in the peer-to-peer network. Participants can use cryptographic signatures to add new transactions to the existing transaction chain, forming a secure, continuous, and immutable chained data structure; from a data perspective It seems that blockchain is a kind of distributed data that cannot be changed.

In 2008, an article titled "Bitcoin—A Peer-to-Peer Electronic Cash System" marked the birth of Bitcoin and the beginning of the global blockchain industry. Since its development, the blockchain has developed from 1.0 to 3.0, from the characteristics of digital currency to the application exploration stage.

The above data comes from the "China Blockchain Industry" by Qianzhan Industry Research Institute "In-depth Analysis Report on Business Model Innovation and Investment Opportunities". At the same time, the Qianzhan Industry Research Institute also provides solutions such as industrial big data, industrial planning, industrial declaration, industrial park planning, and industrial investment promotion.

❻ Blockchain Industry Public Opinion Research Report

Blockchain technology is considered to be the fifth core technology most likely to trigger a disruptive revolution. After experiencing a period of chaos and after the bubble period, withThe intervention of national policies and the implementation of relevant supervision will gradually +B39 get on the right track and develop in a healthy direction. In 2017, blockchain suddenly became popular all over the world and became the focus. If the emergence of blockchain made people in the industry excited at first, and ordinary people had an attitude that it had nothing to do with them and just passed by, then it can be said that blockchain has quickly and deeply entered the public's consciousness. vision. The concept of blockchain was proposed by Satoshi Nakamoto in 2008. Its characteristics such as decentralization, non-tamperability, and traceability have attracted many investors to invest in it. Blockchain has gradually entered various industry fields, bringing not only considerable changes, but also some adverse effects. Analysts analyze and discuss the development trends of China's blockchain industry by collecting and sorting out data related to China's blockchain industry. The rising trend of blockchain popularity can be clearly seen from the network index trend chart of blockchain and digital currencies in the past six months. It turns out that the popularity of blockchain has only increased, and by the end of 2017, there was even an explosive rise. According to the trend chart, it can be predicted that the exponential growth of the blockchain network will show a gentle trend in the near future. The digital currency network index, which is closely related to the blockchain, was not much different from the network index of the blockchain before 2018. That was because the popularity of the blockchain detonated the value of Bitcoin, and many people took the opportunity to follow suit, causing the market to be chaotic for a time. . Since the beginning of 2018, the network index of blockchain has far exceeded that of digital currency. Such changes indicate that more people are focusing on blockchain, which will also be more conducive to the healthy development of blockchain technology. The value of digital currencies represented by Bitcoin has doubled, and ICOs have followed the trend. Financing models such as ICO are both similar to and different from traditional IPO financing methods. It can open up markets on a global scale and gain more development opportunities. However, due to the ulterior motives of many people and the fact that ICOs currently do not undergo any strict review process, chaos occurs frequently in the ICO market. The positive and negative impacts brought by ICO also make countries have different attitudes when facing this mixed market. According to the information table on the attitudes of some countries towards ICO, it can be seen that the most clear-cut attitudes are China and Japan. China completely bans ICO projects and defines them as illegal financing activities; Japan allows ICO projects and takes the lead in establishing a blockchain alliance; Countries such as the Philippines, Russia, and Canada adopt a regulation + development model, do not prohibit ICO projects, and actively build regulatory systems. Since the United States is a federal country, states have different attitudes. It is worth mentioning that the attitudes towards ICOs in Hong Kong and Macau are the same as those in mainland China, while Taiwan is very different. The head of the "Taiwan Financial Regulatory Agency" promised to adopt a more friendly attitude to support enterprises. Development and adoption of cryptocurrency and blockchain technology in Taiwan. The top 10 national blockchain platforms are mainly concentrated in Beijing, Shanghai and Guangzhou. The top 10 national blockchain platforms show that Bitmain, Babbitt/Blockyuan and Huobi occupy the top three positions. The top 10 blockchain platforms are mainly concentrated in Beijing.Most of them were released relatively early, with many episodes before 2016. Generally speaking, the development of blockchain has driven the development of related industries and set off a wave of entrepreneurship. Blockchain-related companies are mainly concentrated in Beijing, Shanghai and Guangdong, which is affected by the high barriers to blockchain technology. Beijing is rich in talent resources and has a good entrepreneurial environment. Shanghai has a unique financial status and has the greatest possibility of incubating the most successful companies in blockchain applications. Guangdong has a strong entrepreneurial atmosphere, which can attract related entrepreneurs. and promote the implementation of relevant enterprises. In addition, Hangzhou also benefits from its excellent Internet financial industry, and the blockchain industry is performing well. With the development of blockchain, related companies will appear in more cities. The popularity of blockchain continues unabated, and a large number of related public accounts have been spawned. It can be seen from the top 10 most influential WeChat public accounts that the number one “Digital Currency Trend Madman” is estimated to have more than 800,000 active fans in the past seven days, and the number two “Wang Tuan Zhang Blockchain Diary” is estimated to have more than 800,000 active fans in the past seven days. The number of active fans is also close to 500,000, and "Bi Lao Ye", who is estimated to have close to 400,000 active fans, is close behind, ranking third. The increase in public accounts also shows that more and more people are paying attention to the blockchain industry. Blockchain is becoming more and more popular. The average salary for related positions was 23,800 yuan before November 2017. By 2018, the average salary had reached 25,800 yuan. According to the skill demand chart for blockchain positions, it can be seen that the most important ones are commonly used development languages ​​(Go, C++, Java). In addition, you also need to have sufficient understanding of cryptography, formula algorithms, smart contracts, etc. In addition, There are also positions with relatively low thresholds such as operations. In general, the talent gap in the blockchain industry is relatively large. Blockchain technology is considered to be the fifth core technology most likely to trigger a disruptive revolution. After experiencing periodic chaos and bubble periods, it will gradually get back on track with the intervention of national policies and the implementation of relevant regulations. , develop in a healthy direction. Blockchain will inevitably produce bubbles when it develops, but these bubbles will gradually become controllable with the healthy development of blockchain. The development prospects of blockchain and the innovations it can bring are unpredictable. From now on, leave this stage to it and watch its performance.

❼ What happened to the blockchain recently?

There is a word recently.

It often appears on the Internet,

It’s amazing to see this word,

but I often don’t know what it means.

The word is called

"Blockchain"

Recently, "Blockchain" has been named publicly again.

What is "blockchain"?

From an academic perspective, blockchain is a new usage model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanisms, and encryption algorithms.

Blockchain is essentially a decentralized database.

Explain this.

Many people still don’t understand.

Hypothetical environment:

Methods to solve blockchain problems:

If you use Family MobilizationWith accounts, the above problem does not exist, because you keep accounts, your father keeps accounts, and your mother keeps accounts. They can all see the ledger, you can’t change it, and neither can your parents. So you can't help the dad who wants to buy cigarettes, nor can you help the greedy dad.

In other words, the blockchain

this distributed digital ledger

records everything that has happened

and the transactions are unanimously approved by the system.

Each block is a ledger.

It can not only record transaction information

but also has more functions.

Multi-functional "Blockchain"

Each block is like a hard drive, with all the information on it saved and then encrypted using cryptography. This saved information cannot be tampered with.

Looks like it

Blockchain has some super technical properties.

Characteristics of blockchain

1. Exceptionally safe: Unlike centralized databases owned by companies or government agencies, blockchain is not controlled by any person or entity, and the data is completely replicated (distributed) across multiple computers superior. Unlike centralized databases, there is no single entry point for attackers, so data is more secure.

2. Non-tamperability: Once entered into the blockchain, no information can be changed, and even administrators cannot modify this information. Once something happens, it cannot be changed. This property is of great significance to the ever-changing and ever-changing online world in which humans live.

3. Accessibility: All nodes in the network can easily access information.

4. No third party: Because of the decentralization of the blockchain, it can facilitate peer-to-peer transactions. Therefore, whether it is a transaction or fund exchange, no third party approval is required. Blockchain itself is a platform.

What will the future development and usage scenarios of blockchain look like?

1. Digital Identity

Many people will encounter the dilemma of "proving that my mother is my mother" when applying for various certificates. With blockchain, there is no need to worry anymore.

Our original birth certificates, real estate certificates, marriage certificates, etc. It needs a central node for everyone to recognize. Once cross-border, contracts and certificates may become invalid due to the lack of a global central node.

The immutable nature of blockchain technology fundamentally changes this situation. Our birth certificates, real estate certificates, and marriage certificates can all be notarized on the blockchain and become things trusted by the whole world. Of course, it is also easy to prove "my mother is my mother".

2. Health care

To put it simply, the blockchain is used to establish a universal record library with timestamps, so as to extract data information from different databases. For example, when you go to see a doctor, you can have repeated examinations without changing hospitals, and you don’t have to go back and forth for medical insurance reimbursement, which can save time and money.

3. Travel consumption

For example, we often use apps such as Ctrip and Meituan to find and place orders for hotels and other services, and each platform earns commissions from them. The use of blockchain is to remove middlemen and create a secure, decentralized way for service providers and customers to achieve direct connection and transactions.

4. More convenientTransactions

The blockchain can make payments and transactions more efficient and convenient. The blockchain platform allows users to create smart contracts that become active when specific conditions are met, meaning that automatic payments can be released when both parties agree that their conditions are met.

5. Strictly control product quality.

If you buy an apple, with blockchain technology, you can know the entire process from production to distribution. There are government regulatory information, professional testing data, corporate quality inspection data, etc. Smart supply chains will make our daily food and commodities safer and give us more peace of mind.

6. Property rights protection

Related Q&A: What does blockchain mean?

Blockchain is a new usage model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms. Blockchain is an important concept of Bitcoin.

It is essentially a decentralized database, and as the underlying technology of Bitcoin, it is a series of data blocks generated using cryptographic methods. Each data block contains a batch of Bitcoin network transactions. The information is used to verify the validity of its information (anti-counterfeiting) and generate the next block.

Blockchain is closely related to people's production and life in the fields of public management, energy, hotel management, transportation, etc. However, the centralized nature of these fields also brings some problems, which can be transformed with blockchain.

The decentralized fully distributed DNS service can realize domain name query and resolution through point-to-point data transmission services between each other in the network, and can be used for certain important infrastructure operating systems and firmware without being tampered with. It can monitor the status and initialization of software to detect bad tampering and ensure that data transmitted by systems using IoT technology has not been tampered with.

❽ What is the blockchain craze and chaos?

According to reports, as blockchain has changed from a cold and obscure professional term, As a hotly debated “hot spot”, many merchants with a keen sense of smell are trying their best to seize the opportunity and use various tricks to “take advantage of hot spots” to take advantage of the opportunity to attract 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”, such asHow to cross the river by feeling for the stones while guarding against "bad money driving out good money" deserves further thought and attention.

❾ How to solve blockchain security issues

One of the characteristics of blockchain projects (especially public chains) is open source. Open source code improves the credibility of the project and allows more people to participate. But the openness of source code also makes it easier for attackers to attack the blockchain system. There have been many hacker attacks in the past two years. Recently, the anonymous currency Verge (XVG) has been attacked again. The attacker has locked a vulnerability in the XVG code, which allows malicious miners to add false times to blocks. After stamping, new blocks were quickly mined, and nearly US$1.75 million worth of digital currency was obtained in just a few hours. Although the attack was successfully stopped, no one can guarantee whether the attacker will attack again in the future.
Of course, blockchain developers can also take some measures
The first is to use professional code audit services,
The second is to understand safe coding standards and nip problems in the bud.
Security of cryptographic algorithms
The development of quantum computers will bring major security threats to the cryptographic systems currently used. Blockchain mainly relies on the elliptic curve public key encryption algorithm to generate digital signatures for secure transactions. Currently, the most commonly used ECDSA, RSA, DSA, etc. cannot withstand quantum attacks in theory, and there will be greater risks. More and more Researchers are beginning to focus on cryptographic algorithms that are resistant to quantum attacks.
Of course, in addition to changing the algorithm, there is another way to improve security:
Refer to Bitcoin's handling of public key addresses to reduce the potential risks caused by public key leaks. As a user, especially a Bitcoin user, the balance after each transaction is stored in a new address to ensure that the public key of the address where Bitcoin funds are stored is not leaked.
Security of consensus mechanism
The current consensus mechanisms include Proof of Work (PoW), Proof of Stake (PoS), and Delegated Proof of Stake (DPoS). , Practical Byzantine Fault Tolerance (PBFT), etc.
PoW faces 51% attack problem. Since PoW relies on computing power, when an attacker has a computing power advantage, the probability of finding a new block will be greater than that of other nodes. At this time, it has the ability to undo transactions that have already occurred. It should be noted that even in this case, the attacker can only modify his own transactions and not the transactions of other users (the attacker does not have the private keys of other users).
In PoS, an attacker can successfully attack only when he holds more than 51% of the token amount, which is compared to 51% of the computing power in PoW.It's even more difficult.
In PBFT, the system is safe when the malicious nodes are less than 1/3 of the total nodes. In general, any consensus mechanism has its conditions for establishment. As an attacker, you also need to consider that once the attack is successful, the value of the system will be reduced to zero. At this time, the attacker has nothing to do except destroy it. Get other valuable rewards.
For designers of blockchain projects, they should understand the advantages and disadvantages of each consensus mechanism, so as to choose an appropriate consensus mechanism or design a new consensus mechanism according to the needs of the scenario.
Security of smart contracts
Smart contracts have the advantages of low running costs and low risks of human intervention. However, if there are problems with the design of smart contracts, it may cause greater losses. In June 2016, The DAO, Ethereum's most crowdfunded project, was attacked. Hackers obtained more than 3.5 million Ethereum coins, which later caused Ethereum to fork into ETH and ETC.
The measures proposed in this regard have two aspects:
The first is to conduct security audits of smart contracts,
The second is to follow the principles of safe development of smart contracts.
The security development principles of smart contracts include: be prepared for possible errors and ensure that the code can correctly handle bugs and vulnerabilities; release smart contracts with caution, do functional testing and security testing, and fully consider boundaries; maintain The simplicity of smart contracts; pay attention to blockchain threat intelligence and check for updates in a timely manner; be clear about the characteristics of blockchain, such as cautiously calling external contracts, etc.
Security of digital wallets
Digital wallets mainly have three security risks: First, design flaws. At the end of 2014, a serious random number problem (duplication of R values) caused users to lose hundreds of digital assets in a certain lottery. Second, digital wallets contain malicious code. Third, lost assets caused by loss or damage of computers and mobile phones.
There are four main countermeasures:
The first is to ensure the randomness of the private key;
The second is to verify the hash value before installing the software to ensure that the digital wallet software has not been tampered with ;
The third is to use a cold wallet;
The fourth is to back up the private key.
