Ⅰ Energy Blockchain Research丨The Development Process of Bitcoin Mining

Bitcoin has not yet reached the growth stage, but as Bitcoin mining speed begins to accelerate , the industry is poised for substantial growth.

In October 2008, when Satoshi Nakamoto published a white paper detailing how to create a new currency system, no one expected that the market value of Bitcoin would soar to 850 billion in less than 13 years. Dollar. Additionally, Bitcoin spawned thousands of other types of cryptocurrencies, formed an entire financial services industry, and evolved into a new asset class that revolutionized money as we know it.

Our company has been involved in Bitcoin mining activities for seven years and has contributed to the development and adaptation of the industry. Below we’ll take a look at some of the lesser-known developments in Bitcoin mining and some of the trends that have a major impact on the industry.

The emergence of Bitcoin mining

Bitcoin is a decentralized currency system that functions like gold and is a limited commodity with a means of storing value. This means that Bitcoin has a limited supply, with only 21 million Bitcoins currently in existence, making it less susceptible to inflation. People who want to use Bitcoin are not subject to government oversight that has the power to change its value or determine users’ access rights.

So where does Bitcoin itself come from? Like gold, Bitcoin must be mined, but instead of using picks and shovels, you do it with computers.

Bitcoin is based on blockchain technology. Miners around the world compete to solve an algorithm so they can add a block to the blockchain. The first person to solve the algorithm can obtain the transaction fees of the block and a fixed reward for the issuance of new coins (currently 6.25 Bitcoins per block), which will increase the circulation of Bitcoin.

When Bitcoin was first created, mining was so easy that miners could mine from their kitchens using laptops equipped with standard central processing units. However, as more and more miners join, the competition for solving the problem becomes more and more fierce, which also means that miners need stronger data processing capabilities and newer hardware equipment. In order to efficiently run more powerful computers, the price of electricity began to be taken into account. Soon, due to the fierce competition in mining, individual mining was no longer profitable.

The birth of a multi-billion dollar industry

To be profitable, mining operations must be scaled up. Currently, new mining-specific hardware has appeared on the market, and miners have installed mining machines in trailers and warehouses so that large mining farms with thousands of mining machines can solve algorithm problems around the clock. Driven by the operational demands of large-scale mine operations, including layout and design, energy, software management, and hardware updates, Bitcoin mining has rapidly grown into a multi-billion dollar industry.

ARK Invest)’s report shows that the cost of hardware to support the ecosystem is approximately $7.2 billion. Additionally, the report states, “We believe that billions of dollars have been spent on the design, production and distribution of Bitcoin-specific hardware since its introduction in 2013.” film, which has also spawned an industry dedicated to manufacturing this kind of powerful and professional hardware.

Although Bitcoin mining is complicated to operate, it is very profitable. Ark Investment estimates that miners can earn 15 billion USD revenue from transaction fees and fixed Bitcoin rewards.

Competition breeds new hardware

Competition for Bitcoin mining continues to increase, but because Bitcoin is a finite Commodities, so mining competition is also limited. This means that mining operations need to run as high-speed as possible with high performance, so as to obtain rewards.

Due to the increasingly fierce competition in Bitcoin mining, the Requirements for computing power, so mining competition has become a competition for graphics cards, and graphics cards are hardware that gamers usually use in high-end games. Later, application-specific integrated circuits gradually replaced graphics cards, which are specifically used for mining. A kind of hardware for cryptocurrency, it is the fastest and most efficient hardware in Bitcoin mining. It is currently only used in mining.

But the hardware relies on chips, although the development of chip technology continues to accelerate. , but chips are still in short supply. This means that mining operations need to be planned and upgraded in advance, and the necessary hardware is often sold out. For example, Bitmain is facing a shortage recently.

New technologies are most likely to be profitable

Similarly, Bitcoin mining needs to keep up with the pace of technological development and make mining hardware bigger, better, and faster, because once efficiency lags, profits will be damaged. Today, technology continues to surpass innovation, so Mining not only needs to keep up with the purchase of new hardware, but also needs to install new hardware quickly. This is because time is of the essence and a delay of even a few days can cause serious damage, so many mining operations (such as our company's mining) All have rented Boeing 747s to reduce transportation time.

The number of Western miners is increasing

For a long time, more than half of the world’s mining energy has come from China, mainly due to the cost of setting up factories in China Lower and faster to ship. But as China steps up its crackdown on Bitcoin mining, those advantages are disappearing. According to Wired, “The geography of Bitcoin mining may be changing,” The business may shift to North America, Europe and Latin America. Miners also plan to look for mining sites in Nordic countries, Canada and the United States, where there is a large amount of cheap sustainable energy, such as wind energy, solar energy and water energy. < /p>

The future of Bitcoin

Although Bitcoin has seen a lot of volatility recently (which is nothing new), the future of Bitcoin is bright, its value will continue to rise, and it will attract New investors. As more and more people startPeople will also find more value in Bitcoin by understanding its origins and how it is mined.

II 36Kr Exclusive Interview｜Silicon Valley Senior Investor: Web3 is not equal to blockchain, and has nothing to do with “coin”

Different technologies Role in the Web3.0 landscape | Image source: Draper Dragon

"User autonomy is the core of web3, decentralization is not"

36Kr: Now when people talk about Web3 "Decentralization" must be mentioned. "Decentralization" has become an ultimate goal.

Wang Yuehua: That is a misunderstanding. Web3 can be partially centralized and does not necessarily have to be "decentralized".

The core of Web3 should be "user autonomy". Because the basis of web3 is "decentralized" data. The source of data must be decentralized. The so-called "decentralization" means that the data is authorized and managed by the user himself, that is, user autonomy.

If "centralized" services want to achieve "user autonomy", the difficulty lies not in technology, but in how to make users trust you and that you will listen to them? This is hard to convince users to believe.

But if you are decentralized on a technical level, you have essentially met the requirements and there is no need to persuade. Obviously, "decentralization" is the most convenient path to achieve "user autonomy". Everyone chooses a path to take.

36Kr: Can “user autonomy” be achieved in China?

Wang Yuehua: Complete "user autonomy" is unlikely. But there is a question of degree, such as whether to achieve 1% user autonomy or 99% user autonomy.

It depends on the government department. Data rights involve many dimensions, such as dividend rights, operating rights, management rights, etc., and can be divided into hundreds of categories. If any of them involve national security or organizational privacy, users will not be allowed to use them.

36Kr: Since web3 does not necessarily need to be “decentralized”, how to understand the relationship between web3 and web2?

Wang Yuehua: In the Web1 era, the Internet was not centralized because the infrastructure at that time was underdeveloped (for example, there was no cloud computing), so "centralization" was not possible and it was impossible to form a large-scale monopoly.

In order to pursue efficiency and reduce costs, the Web2 platform has become centralized. Web2 is nothing more than "centralizing" user accounts and user data. Now that Web3 technology is complete, centralization can be broken again. Web2 companies can return data rights to users and continue to maintain the original business model, which is no problem.

From Web2 to Web3, it is transition and iteration, they are not separated. There are many projects in the United States from Web2 to Web3, which may not be of concern in China.Heart.

36Kr: "Function protocolization" is often mentioned in Web3. How to understand its commercial value?

Wang Yuehua: Web3.0's layered architecture based on "functions" means a large number of new business opportunities.

The economic dividends originally attributed to a certain Internet company will be redistributed according to the functional combination. It is no longer possible for various protocols to obtain greater economic benefits through the monopoly of certain resources, especially the monopoly of data resources. Instead, only through the improvement and optimization of functions can they reflect their own value and achieve greater benefits. This means more fairness and openness.

More protocols with different attributes and rich functions will have the opportunity to enter the service chain and participate in benefit distribution. It’s a huge opportunity for entrepreneurial teams.

In addition, a very sophisticated incentive system can be established based on smart contracts. This incentive system will directly motivate all teams and individuals who have joined or want to join the web3.0 ecosystem.

(Editor's note: A smart contract is equivalent to coding an agreement and putting it on the Internet for execution. The agreement can include rules such as application gameplay, equity allocation, buyback terms, etc.)

DAO is not suitable for all types of work

36Kr: DAO still seems to be unable to get rid of the problem that the organization is made by a few people making decisions?

Wang Yuehua: DAO is not suitable for all types of work, nor is it suitable for all business models. It's efficient in some situations and inefficient in others, depending on what you're using it to achieve.

The DAO model is more suitable for work collaboration. Many so-called associations in the United States, such as electronics associations, industrial associations, etc., have long used the DAO model to operate, but they are not called DAOs and do not use smart contracts.

36Kr: What is the ideal DAO?

Wang Yuehua: The core logic of DAO is that everyone is for me and I am for everyone. Its functions and properties can be implemented through the deployment of smart contracts and change with organizational goals. The smart contracts are like stacking Lego blocks. The members of the DAO are added one by one according to the rules. The rights of each member are established based on different dimensions such as contribution, credit rating, participation, etc.

36 Krypton: It is the people who make up the community, and profits are what the company pursues. Therefore, DAO can never make big money, but its incubation team can. Do you agree?

Wang Yuehua: DAO is an operating mechanism, not a profit-seeking institution. Properly speaking, DAO can be used as a tool and a platform.

The Web3 industry is being reshuffled

36Kr: In the past year, Web3 has experienced a boom and entered a bear market. What changes have occurred in the portraits of entrepreneurs you have come into contact with?

Wang Yuehua: Most of the entrepreneurs I contacted in the first half of the year were crypto-native. In the second half of the year, many entrepreneurs came from the traditional Internet, such as Ant, Tencent, Alibaba, and the Internet. This is a big change.

Crypto native people prefer to capture users in the currency circle. Their methods of building communities and fans are relatively grassroots and not very systematic. Entrepreneurs who have transitioned from Web2 have relatively stable thinking, whether they are dealing with traffic or product design.

36Kr: Over the past year, NFT transaction volume has been declining. Has NFT bid farewell to the era of sky-high prices?

Wang Yuehua: It must be a complete farewell. For a long time, the mentioned NFTs basically belong to PFP (avatar, picture category). The value of PFP is relatively small, and the value can be amplified only by functionality.

NFT should have three attributes: asset, collection, and functionality. PFP projects basically only have asset properties. They only seek recognition from a group to support their value, and their asset properties are pushed up.

The biggest market for NFT in the future is functional. It must be functional and useful. The point is to be useful.

36Kr: After the current crypto bear market, which projects do you think will be shuffled away and which projects will remain?

Wang Yuehua: It is easier for companies in the protocol field to stay, while those in the application field will be shuffled.

Because of the application type, their traffic is originally the traffic of the currency circle. If the market is bearish, these traffic will also disappear.

On the contrary, companies with traffic in Web2 have opportunities because they have advantages in capital and traffic. For example, they can direct traffic to Web3. There are some Web2 projects in the United States that have been transferred to Web3 very quickly because they carry their original traffic.

36Kr: Will the future development space of cryptocurrency become smaller and smaller?

Wang Yuehua: No, it will only be better. Some central banks have issued digital currencies, which may not necessarily be called cryptocurrencies, but they are of the same type and belong to digital currencies, and their volume will become larger and larger. Once regulation keeps up with the development of cryptocurrencies or digital assets, governments will encourage its development.

36Kr: Why encryption must be the future? What is the reason you believe in most? Apart from the financing function, tokens seem to be of little use to the Web3 team?

Wang Yuehua: Encryption is fundamentally interpreted as a privacy protection. Privacy protection is a basic need because without privacy there is no freedom and that is definitely the future. The role of Token is actually to open up the possibility of another business model or even business format. Something as simple as a certificate, a badge, or an asset can be run in the form of a Token.

Ⅲ How to target 5G, blockchain,New risks related to stability emerging from new technologies such as artificial intelligence and new business formats such as the sharing economy

New technologies are bound to bring about higher leaps.
“The development of digital economy must rely on the construction of network ecology. The so-called network ecology means connecting dots into lines and connecting lines into surfaces to promote communication, exchange and sharing on a larger scale.
Industrial Internet in smart factories The in-depth integration of industrial equipment terminals has greatly improved the intelligence and informatization of industrial equipment terminals, and has also triggered a series of new security challenges. Taking history as a lesson, various new attack technologies and means for industrial control systems have emerged in an endless stream, such as Stuxnet virus, Viruses such as Flame Virus and BlackEnergy have clear targeted attack characteristics, which have had a serious impact on enterprise production safety and even national security. 5G combined with blockchain technology can help build a future-oriented, smarter, safer and more reliable Xin’s smart factory.

IV 36Kr exclusive | Mango TV will soon launch a digital collection platform, and the gameplay will be linked to the business

Article | Chen Xining

Editor | YANG It is the TBFT consensus algorithm and will be launched on the digital collection platform based on the Ray Chain in mid-March. Mango TV is backed by Hunan Radio and Television. This is also the first time that a state-owned enterprise has deeply involved in the digital collection platform business. 36 Krypton confirmed with Mango TV After receiving a positive reply, this means that there will be one more player in the digital collection track.

Since 2021, NFT and blockchain have become popular in China along with the concept of the Metaverse. Among them, platforms such as Alibaba, Tencent, Xiaohongshu, and JD.com have begun to launch their own digital collection platforms. According to relevant practitioners, the current annual GMV of the leading domestic digital collection platforms has exceeded hundreds of millions. This may lead to a In conclusion, even if they do not have investment attributes for the time being, digital collections, as an emerging industry in the trendy toy industry, may still have greater commercial value to be explored.

In China, digital collection platforms mainly emphasize artistry and collection. , due to regulatory requirements, there is currently no platform that can support transaction functions between consumers. This has almost eliminated the possibility of speculation and investment in digital collections, which will also be maintained on Mango TV’s digital collection platform.
< br /> As Mango TV owns many drama and variety IPs, the digital collections it launches will definitely include its IPs. In addition, Mango TV will also accept authorization from other cooperative IP parties to maintain a certain openness of the platform.

Data shows that Mango TV has more than 50.4 million effective members as of the end of 2021, and users under the age of 24 account for more than 65%. There is a certain degree of overlap between this part of consumer users and digital collection consumers. According to the person in charge of Mango TV digital collection platform throughThe project was prepared in July 2021. In addition to expanding the influence and commercialization of the Mango TV brand, operating existing users is also one of the purposes.

After several years of development, Mango TV is no longer a single content platform. It also has a large number of businesses centered around content, including Xiaomang e-commerce, trendy play development, offline live entertainment, etc. The digital collections it issues may also become a "passport" to connect these business scenarios in the future.

The project leader told 36Kr that the digital collection platform launched this time is currently embedded in Mango TV and Xiaomang e-commerce. Users who purchase the first batch of digital collections will also receive certain special benefits. Rights and interests may be reflected in the recognition of avatars and future linkage with business.

“Laying out the digital collection platform business is a step in exploring the Mango Metaverse.” said the person in charge. Currently, Mango TV’s virtual human team, algorithm team, VR team and game team are preparing for the next step of research on the Mango Metaverse.

IV Where to find analysis and research reports for various industries

Information collection channels: Common channels include company official websites, consulting company official websites, securities firm research, databases, WeChat, Zhihu, Search engines, web crawlers, etc. So under what circumstances should we use which channel? Introduced one by one below.

Company official website: Generally speaking, the company's official website contains a lot of information, such as company introduction, product introduction, company annual report, prospectus, etc. The reliability of these information is usually relatively good. The annual report of a listed company will analyze the company's business sales, profit drivers, etc. in the business analysis content. Therefore, when you want to know the business development of a listed company, the annual report is a good choice. The annual reports of listed companies can be obtained from the stock exchange, the company's official website, Juchao, Snowball and other channels.

Consulting companies: Consulting company reports can usually help us know non-public information, because consulting companies usually have their own methodologies to conduct their own qualitative analysis of the market, market research, etc., so they have insights into consumers. To study and judge industry trends, we usually look to reports from consulting companies, but there is also a problem with data that is often difficult to unify. Consulting companies on the market are usually divided into market research consulting companies and management consulting companies, with the former generally serving the latter. Market research consulting companies such as iResearch, Nielsen, and Ipsos usually provide their own insights in consumer research, industry analysis, etc., but they do not provide strategic decisions for corporate development. The research results of such consulting companies are often available for free download on their company official websites and can be used as a source of research data for our industry. Management consulting companies will hire market research consulting companies to provide specialized research and analysis when necessary, and the management consulting companies will give specific strategic suggestions to enterprises. Of course, companies like McKinsey, Bain, BCG, Roland Berger, etc. will also share their industry insights on their official websites. This informationThey are all important sources of information that help us make industry development judgments and business model analyses.

Brokerage reports: Most of the research reports of brokerages are for listed companies and unlisted leading companies. Therefore, when you want to understand a certain industry in depth, you can consider looking for 10 in-depth analyzes and study them carefully. Even if you know something about the industry. The latest developments of listed companies and company strategic actions can be found in the research reports of securities firms. Industry data can also be found here, but there may also be problems with inconsistent data reported by multiple securities firms. In this case, cross-validation is needed to select appropriate values. Here I recommend a website I commonly use for checking brokerage reports, Luobo Investment Research.

Professional database: Professional databases generally charge a fee, but the information is also complete. If you have the conditions, you can consider Wind and Huibo Intelligent Strategy Terminal. Of course, there are also free ones, most of which are government department websites. For example, the National Bureau of Statistics can check industry development data, population data, GDP data, etc. In addition, there are industry-related Ministry of Industry and Information Technology, finance-related China Securities Regulatory Commission, Banking Regulatory Commission, stock exchanges, People's Bank of China, import and export-related China Customs, patent-related national intellectual property websites, industrial and commercial information disclosure systems, and corporate equity checks. Check the structure of QiChacha/Tianyancha, government official websites at all levels to check government policies, industry associations in various industries, and population status inquiry from the Bureau of Health Statistics.

Search engines: Learn to use WeChat, Zhihu and other search channels. You can often get summaries and sharings from some people in the industry. This is also my favorite channel for obtaining information. Although it is fast to use the search engine directly, the authenticity of the information needs to be distinguished. It is suitable for fuzzy search when you don’t know where to start, and then trace back to the source. Adding pdf after the keyword, adding "" to the keyword, adding the website name, etc. will usually have unexpected results.

Using web crawlers requires a certain technical foundation. Regarding information search channels, please read my previous answer.

Channel judgment: You will find that it is easy for us to obtain information from listed companies and mature industries through annual reports, brokerage reports, prospectuses, regulatory agencies, and professional databases, but how do we obtain information from some small businesses and emerging industries? Where is the information? The answer is expert interviews, public news, consulting firms, and consumer research. As mentioned before, consulting company reports often have inconsistent data standards. At this time, multiple data sources are needed for verification. Based on the assumptions made by the consulting company, whether the time is up-to-date, the logic of data derivation, channel sources, etc., you can comprehensively judge what you should do. Data taken.

Obtain information through non-public channels: For a lot of information, you may not be able to obtain it through public channels. At this time, questionnaire surveys, cold calls, expert interviews, and focus groups can be used for brainstorming. Methods such as storms and field surveys have become channels for consulting companies to obtain non-public information. Of course, each method has its own advantages and limitations, which I will analyze one by one below.

Expert interviews: The characteristics areExpensive, but highly efficient, you can gain an in-depth understanding of non-public information, such as knowing the competitive landscape of the industry, future industry development trends, the key success factors of the industry, the core competitiveness of the company, etc. At this time, industry interviews should pay attention to time control, usually between half and one hour. Usually we can use expert database companies such as Kaisheng and Sanqiao to help us introduce experts. For the purpose of the interview, it is most appropriate to look for experts who have just resigned. After all, the experts who are still working have some concerns. Prepare questions in advance, usually about 10, and put the important questions at the front. The purpose is to test the professionalism of the experts to determine whether to continue the interview, which can reduce costs and improve efficiency. During the whole process, you should pay attention to the rhythm, guide the experts to the questions you want to know, and record the information well. When it comes to privacy issues, you need to learn to consider them from an expert's perspective. For example, if you ask directly what is the core competitiveness of your company? It often embarrasses experts. Let’s change the question. For example, if you were to run a business similar to yours, what do you think is most important? This often reduces the mental burden on the expert. As for data-based questions, be careful not to ask a large number of key data indicators in one go. It is often difficult for people to answer in one go. Remember to decompose the problem, a complex problem into multiple problems, proceed layer by layer, and finally summarize and confirm with the other party.

Cold calling: time-consuming and labor-intensive, but you can also get information from expert interviews. Because you are calling a stranger, you need to make reasonable identity assumptions and psychological construction. At the same time, cross-verification of the information obtained is required to ensure that the person being visited does not answer randomly. The number of questions prepared should be no more than 5, if you want to know more than one question. You can visit again every few days. When meeting the front desk, you should use a short and direct tone, provide the company's employee names, etc. to increase trust. Learn to think from the other person's perspective. What benefits will this call bring to the other person?

Questionnaire research: generally includes clarifying the purpose, designing questionnaires, distributing, recycling and analyzing the questionnaires. First of all, let us clarify the purpose of this questionnaire survey, the objects of the survey, and the information that needs to be collected. Regarding the design of the questionnaire, important questions should be placed first, because people are often the most energetic at the beginning. Therefore, in order to ensure quality, the time spent on the questionnaire should not exceed 20 minutes. At the same time, similar questions should be set in different questions for cross-fertilization. verify. Generally speaking, survey questionnaires should be designed and released on a small scale first to look for problems, such as whether the way of asking questions is inappropriate, whether there are ambiguities, and whether there are any imperfections? For example, there is no need to use words with different understandings like occasionally or almost never. The options should be independent of each other and completely exhaustive. When encountering sensitive issues, find ways to eliminate the other party's concerns. For example, remind the other party that the results of the questionnaire will be strictly confidential and do not lead the other party to draw conclusions. Answers etc. After the modification is completed, large-scale delivery will be carried out, followed by collection and analysis.

Field research: When choosing a place for field research, you should consider the two dimensions of time and location. First of all, time should be considered in the morning, noon and evening, during the weekend and working days. The location should be in the city center, suburbs, business districts, and residential areas. Survey samples should be selected so that they are more representative.

Focus group: The focus of the focus group is to allow each participant to fully express his or her opinions. How to do this? Of course, the best way is to let everyone clarify the purpose of this discussion and let participants prepare in advance, so as to avoid the initial cold start. It is best to introduce yourself before starting a group discussion. People are often willing to share their experiences with people they know well. Since it is a brainstorming, the design questions should not be yes or no questions, but should be able to arouse extensive discussion. The difficult questions should be placed in the middle, because the middle period is the most active period for everyone. The role of the moderator is to remain neutral, clarify the topic, and ensure that everyone is on the right path. At the same time, don’t forget to record the content of the discussion.

Ⅵ Are the current dating websites reliable? Are there scammers?

Someone has said that the great thing about the Chinese is that they turn everything into a business. In fact, this is not true. Everything is a business in itself. It is just a matter of whether you do it or not. When we see that changes in a society actually start from a business, we may be able to better understand why our society has undergone such profound changes. So is it reliable for a Chengdu matchmaking agency to launch an online dating website?

Thirteen years after the opening of a matchmaking agency, dating websites began to appear on the Internet, and more social relationships were reintegrated. Since then, a more profound revolution in social relations has gone on for another 13 years. I believe anyone would say that our society has become more tolerant and more accepting of new lifestyles in these years. Progress in this area all started with a matchmaking agency.

“At that time, people were keen to participate in group activities, which were arranged by the organization and were safe and guaranteed.” Mr. Wang, a senior marriage and love expert in Chengdu, said that it was very fashionable for older young people to participate in similar group activities. things.

But after retirement, I still want to have my own job and concentrate on solving the problem of "finding a partner." Teacher Wang said that in 2004, a matchmaking agency organized by retired government cadres in Chengdu was established. It was staffed by retired government officials and was affiliated to Chengdu City to provide single marriage services and provide staff.

When the son of a leading cadre came to the institute to register, he asked to find him the daughter of a division-level cadre. The matchmaking agency did not allow him to register, but gave him ideological education, criticizing him for being a "well-matched" as a secular concept, so much so that the son of a cadre was later embarrassed to reveal his father's name.

In fact, it seems that after these years of development, there are more and more matchmaking markets, mostly in cities. Dating agency business is also booming. Now in Chengdu alone, there are more than 500,000 single men and women aged 35 to 50. After single men and women register as members of a dating agency with valid documents, the dating agency will introduce suitable candidates from among its members based on their spouse selection requirements. According to industry insiders, some largeDating agencies have tens to hundreds of thousands of members. But they all pass real-name authentication, and some even dating websites require real-name management. Said the person in charge of Chengdu Zuncheng Love.

Ⅸ Are today’s dating websites reliable? Are there scammers?

Editor’s note: Kari Paul recently wrote an article titled New technology aims to thwart online dating fraud. It briefly introduces some of the measures currently taken by dating websites to prevent users from being deceived, and warns us to be cautious when dealing with personal information!

An American woman met a man who claimed to be a captain in the U.S. Army on Tantan, and then quickly fell in love with him. The man promised her that as long as he had money to return home, he would take care of her and her children. By the time the woman realized she had been scammed, she had already called the man more than $700. Later, the man used nude photos to blackmail her for more money. The woman complained to the FTC: "I don't knowI wonder if you can help me, but I think it would be unethical to lie to me just because I am lonely and vulnerable. ”

Treat singles as prey Malware has swept through Tantan and other software, trying to trick their bank account passwords and other important information. Scammers will make up fake identities to gain trust. Between 2015 and 2016, these scammers caused nearly 50 million deaths in the United States. Thousands of dollars in losses.

So, software developers have begun taking steps to ensure that their users are meeting future partners, not scammers.

Based-based apps like Grade and Tinder Location-based dating software requires users to link to a Facebook account to increase the transparency of age and name information. On Facebook, the number of times the date of birth can be modified is limited, and cannot be modified multiple times in a short period of time.

There are now many services to reduce risk. Legitifi, a California startup, launched identity verification software in early 2017 and had 27,000 users sign up. Legitifi will connect users’ existing social media software and verify their identity across multiple platforms. Names and photos match those on ID. Users of online dating sites can ask to see other users' Legitifi profiles. The service also has other security methods, including checking for documented sexual assaults.

Whether the privacy policy is legal, such as Facebook and Twitter.

Legitifi stated that it is not a marketing company and will not store user information after the user logs out of the account. Matt Condensa, chairman of Legitifi, said: "According to our Privacy Policy, we will not share or sell user information, and our accounts can also be canceled. ”

John Challahan is the chief technology officer of security company Veridium. He said that privacy policies will also change, especially after a company is taken over by another company. Blockchain technology is not controlled by any company.A third party may be a more secure authentication route. Blockchain is the encryption technology of Bitcoin. That is, when people use Bitcoin to trade, the transaction information will be sent to the computer for verification. Once the transaction is successfully verified, the transaction information is added to the ledger containing all transaction information. This ledger is called the blockchain. Because the blockchain is based on computer verification, it cannot be tampered with. IBM, Acccenture, and Microsoft have also launched identity authentication based on blockchain technology in recent months. Challahan said: "We are just getting started, but I am in favor of enterprises using two-party authentication systems."

Mike Gross, director of product management at Experian Global Fraud & Identity, believes that blockchain technology is complex and ordinary people cannot implement it. It will be difficult, and joint verification may be more convenient. He said that we need an authentication system that can be fully trusted to verify the personal information of dating website users. For example, Facebook and Twitter require users to use passports, driver's licenses and other documents for real-name authentication.

“Be careful when giving out personal information,” Callahan said. "Perhaps the most valuable thing now is your digital information."
