Ⅰ Why do blockchain and currency circles like to use the one domain name?

First of all, let’s talk about the one domain name. This is a relatively new top-level domain name. The top-level domain name is in recognition and recognition. , promotion is very beneficial. The meaning of one in English is one. It has a high degree of recognition, no need to remember, and a photographic memory. One is the word second only to the in the English world.

Secondly, for many unconventional (innovative) people, they hope that they are unique in some aspects. In this case, they can register such a domain name to express the uniqueness of the corresponding industry or a specific aspect. ideas and pursuits. The name of Han Han’s magazine is one.

Thirdly, the one domain name has room for appreciation and has great potential for appreciation.

Based on the three guesses made by Yi Zao, have you discovered the temperament of the currency circle? Haha

II Is the Columbus cat blockchain project good or not? I don’t know which of the messy things mentioned on the Internet are true

Brother, you must not be technical, the Internet is stupid D i u too There are too many monsters and monsters to evaluate the blockchain. Often these people only have a superficial understanding of blockchain, or even nonsense. I had studied some technical development before, but then I started working in the media industry because I was afraid of going bald. Although after I entered the industry, I discovered that there was still a risk of going bald...
Getting back to business, let me first analyze the routines of media platforms from a media perspective. If a company needs to develop, it needs a certain public opinion environment, especially in emerging industries. What will the media do to target emerging industries? They will publish false reports or even malicious remarks about this industry. These are often things done by small media companies, so why do they do this? It’s very simple, to earn traffic. Fierce remarks often attract the most attention. Such articles can also easily incite the emotions of netizens, thereby increasing the number of readers. quantity. In this way, it will be very simple to monetize traffic, and the capital for receiving advertising will also become higher. The more vertical coverage an article has, the more valuable the vertical advertising will be. For example, if I am a self-media practitioner and I have been posting untrue remarks about the blockchain industry, and suddenly one day a blockchain company wants to find me to publish a report, then I can severely punish it. The land is asking for a price.
Most of the false statements on the Internet are divided into several categories: false rumors are spread among small websites and small media. Rumors start from being taken out of context and made up, and then they will be further escalated as they are passed around. The article intercepted some evidence and spread an upgraded version of the rumor that seemed to be justified. When many celebrities or company leaders see this, their first reaction is: When did I say this? The second reaction is to laugh. As for the media, hey, that’s normal. What's more, you have no choice but to spend money to find the media to publish an article to explain, and another group of people will accuse you of whitewashing. If you don't make a statement, you'll be acquiescing. This vicious cycle goes on one after another. Aren’t some companies just ruined in this way? Regarding the above content, I would like to give the questioner a clear explanation.How to identify, first: pay attention to check the level of the media that publishes the article. Just take what the small media says as a pleasure but don’t take it seriously. Second: Is it released on its official platform? If not, how can anyone know so much inside information?
Let me analyze it for you from a technical perspective. What’s wrong with blockchain technology itself? It’s just an emerging technology. In fact, it can’t be counted. It was first used in Bitcoin. It's just that there is a delay for the general public to be exposed to these, just like the routine models in big cities will be extended to small cities after a few years. Columbus cat does have certain strength in the technical circle, and its technical reserves are still sufficient. It’s just that it will definitely take a long march to achieve comprehensive business development. Let me give you an example: the online payment system may have been developed long before Taobao came out, but the technology cannot be applied immediately as soon as it is available. , first you have to convince others to believe in you before you can really apply it. Dad Ma successfully convinced the Chinese women, so he succeeded. Blockchain itself is a cross-era technology, and better advancement requires the joint efforts of more dedicated entrepreneurs.

Ⅲ A blockchain domain name is actually sold for tens of millions of dollars. Is it extremely valuable or is it a deliberate hype?

Advertising is an important way for companies to promote their own culture and products. As for the channels and methods of corporate advertising, they are also the Eight Immortals crossing the sea, each showing its magical powers.

Real advertising is not about creating an ad, but about getting the media to discuss your brand and achieve advertising. ——Philip Kotler

Today, in the field of blockchain, some companies have taken Philip Kotler’s famous saying to the extreme.

Recently, a piece of news detonated the entire blockchain circle. According to foreign media reports, an “encrypted” domain name related to cryptocurrency, Ouyi, was revealed to have changed ownership of a digital currency terminal on July 8, and the buyer was the digital currency credit card company Monaco.

It is understood that the domain name was successfully traded for US$12 million, which is approximately RMB 79.27 million.

For a time, people in the blockchain circle were shouting that the world is so crazy. They are speculating on tokens, games, and concepts. Now, even blockchain domain names have begun to be speculated?

Some people even ask similar questions on the blockchain forum, and there are still many people paying attention to blockchain domain name information.

Driven by curiosity, the author went online to check the information on the tens of millions of dollars worth of the Ouyi domain name.

The OuYi domain name is a famous domain name developed by the University of Pennsylvania in the United States.Cryptozoology researcher and professor Blaze registered in 1993.

This domain name can be associated with the blockchain because "Crypto" is the abbreviation of cryptocurrency "Cryptocurrency" and can directly represent the digital currency industry. It is most suitable for building related websites. .

Monaco was established in Switzerland in 2016. In addition to debit cards and tokens, it also has mobile wallets and cryptocurrency investment businesses.

The original official website domain name is "Mona.CO". Although it fits the company's brand name relatively well, in terms of dissemination and publicity, it is definitely not as extensive as "Ouyi".

I have never doubted the popularity of blockchain, but I still don’t believe that a domain name related to blockchain is worth tens of millions of dollars.

In fact, the author also read a similar news in March.

A blockchain domain name "CryptoGame.com" was sold for US$85,000, which is approximately RMB 540,000.

Out of curiosity, the author also entered this website and found that it is a platform about blockchain games, and this game platform is also quite unique.

Not only does the platform sell tokens on its own, it also provides currency-to-crypto transactions, and users can trade by themselves based on the digital currency exchange rate.

At the same time, players have unique ownership of their own property in the game and can choose to trade props and assets in the game to obtain profits.

For such a promising blockchain game platform, its “CryptoGame.com” domain name is worth just over US$80,000. How come just 4 months later, a similar "OUYI" domain name was sold for US$12 million?

Maybe it’s because one company does digital currency transactions and the other company does blockchain games, and the two cannot be compared together.

Although the author agrees with this statement, I am still deeply skeptical that a blockchain domain name can be sold for tens of millions of dollars.

It wasn’t until one day when I was chatting with a person in the industry that I suddenly realized it.

A word awakened the dreamer, which reminded me of the ancient Chinese story of "a thousand gold buys a horse bone".

Once upon a time, there was a king who loved horses and wanted to buy a thousand-mile horse at a great price. But after three years, there is still no harvest.

At this time, a low-ranking courtier in the palace volunteered to stand up and said: "Please give me this mission!" The king nodded in agreement.

In less than three months, the young courtier found a good horse that could travel thousands of miles a day. But when he was about to buy a horse, the thousand-mile horse died.

After thinking for a while, he still spent 500 gold to buy the dead horse's bones. Then he took the body of Chollima back to the palace to report to the king.

All the king saw was the body of the Chollima. Of course he was very angry and shouted angrily: "What I want is a live horse. What's the use of buying this dead horse? Didn't you waste 500 gold in vain!"

The courtier smiled and said: "Please calm down your anger, gold is not in vain. You are willing to spend 500 gold to buy a dead horse. If the news spreads, people will believe that you sincerely love good horses." The king knows the goods and keeps his word.

In this way, someone must come to offer horses."

Sure enough, within a year, the king got three horses from others. A thousand-mile horse offered on his own initiative.

A king spent 500 gold to buy the carcass of a thousand-mile horse. It seemed like he was suffering a loss, but later he exchanged it for three thousand-mile horses offered by others, which turned out to be a huge profit.

In this story, the author also saw a very successful advertising plan.

Thinking back to the previous blockchain domain name that was sold for US$12 million, the author suddenly became enlightened. Still a familiar recipe, still the same taste.

The drunkard’s intention is not to drink. Regardless of whether the Ouyi blockchain domain name is worth tens of millions of dollars, the company’s hype and advertising effects have already been seen.

Not only in foreign countries, but also in the Chinese blockchain circle, Monaco, a digital currency credit card company, spent US$12 million to buy a blockchain domain name Ouyi.

This advertising method is similar to the way the Long Island Iced Tea Company changed its corporate name in December last year.

At the end of 2017, The Long Island Iced Tea Corporation in the United States changed its company name to "Long Blockchain Corp". As a result, its stock price that day Just from $2.5 before the market opensIt was once close to US$15, a surge of 500%, and the market value also increased from US$23.8 million to more than US$100 million.

The author still remembers the Long Island Iced Tea Company, and believes that this Monaco company will be an interesting topic in the blockchain circle for a long time to come.

IV Domain name system and blockchain

This centralized domain name registration management method contains the risk of abuse of power by domain name management agencies. The registry operator only controls the registered domain name information database under the top-level domain under its jurisdiction. Once the functions of the registration operator are destroyed or the domain name management personnel misoperate, the availability of certain domain names will be threatened, such as domain name data being tampered with or Deletion causes the domain name to fail to be resolved normally. In addition, registrars control the platform for domain name registration and management. If the registrar intentionally or unintentionally modifies the domain name data submitted by the registrant, it will also lead to domain name security issues. The opacity of domain name registration management provides room for abuse of power. Even if a governing body is acting irregularly, others will not be able to learn of its irregularities.

Therefore, in the current domain name registration management system, the domain name data associated with the domain name is completely controlled and maintained by the domain name registration management operation agency and registrar service agency to which the domain name belongs. There are problems caused by the registration management operation agency being attacked. Risk of data being changed or deleted due to single point of failure or staff misoperation. In addition, the opaqueness of the domain name registration management process brings uncontrollable factors to the standardized registration management of domain names.

The emergence of blockchain technology provides a solution for decentralized domain name registration management. Blockchain is a distributed ledger technology that does not rely on trusted central nodes. It uses cryptographically strict transaction verification rules and rigorous chained data structures to ensure that the data in the ledger cannot be easily tampered with. At the same time, it uses consensus algorithms to Account book data sharing is realized in a peer-to-peer network environment. Combining blockchain technology to design decentralized solutions to security issues existing in the domain name registration and management process, using blockchain's distributed ledger to store domain name data, replacing the domain name database maintained by the registration management operating agency; developing domain names based on the consensus of all parties The rules of registration management are written into smart contracts, and the non-tamperable and traceable characteristics of the blockchain are used to ensure the transparency of the domain name registration management process, thereby preventing the risk of power abuse contained in the centralized domain name registration management scheme.

Since the present invention mainly studies the use of blockchain to reconstruct the domain name registration management system, the background technology summarizes the research status of distributed domain name registration management services combined with blockchain technology.

Namecoin[1] is the first project to combine domain name services with blockchain, using blockchain to build a decentralized domain name system. Namecoin supports registering names under a specific namespace, updating name-bound data, transferring names, and resetting names.Word expiration time and other operations. The registered name in Namecoin adopts a two-stage submission method. First, the hash value of the name is submitted to reserve the name, and then the real registered name is submitted. This method can prevent the name registration operation from being registered before it is confirmed. Namecoin contains a ".bit" namespace, which is similar to a top-level domain. The names registered by users are all under this namespace. However, ".bit" is excluded from the ICANN domain name system, and its registered domain name can only be resolved through a special browser provided by Namecoin. Muneeb et al. [2] proposed Blockstack based on Namecoin development and operation and maintenance experience, using technologies such as layering and virtual chains to migrate domain name services to the Bitcoin system. On Blockstack, users adopt the two-step process of "booking and registering" to obtain name ownership. Unlike Namecoin, the cost of registering different names is not fixed. Blockstack uses a price function to price based on the length and characters of the name to prevent short domain names and meaningful domain names from being registered in large numbers. Ethereum Name Service (ENS) [3] is a distributed, open and extensible naming system based on the Ethereum blockchain. Its main function is to map human-readable names to machine-readable names. identifier. ENS consists of two parts: registration and parsing. Registration is completed by a smart contract that maintains a list of all domain names and subdomains and stores three key pieces of information: the domain name owner, the domain name resolver, and the cache time of the domain name record. The domain owner can be an external user or a smart contract, and the owner can set the name resolver and cache lifetime, transfer domain ownership to another address, and change ownership of subdomains. Handshake[4] is an open source blockchain domain name project established by Joseph Poon, the founder of the Bitcoin Lightning Network, in 2018. It focuses on top-level domain name registration, transactions, resolution and domain name ownership certification, aiming to change the current centralized governance of domain names. pattern. The goal of Handshake is to maintain root zone files in a distributed manner and replace the root server. Handshake is compatible with existing DNS. The system initially includes all domain names in the ICANN root zone and the top 100,000 domain names ranked by Alexa. These domain names are called reserved domain names. Handshake uses DNSSEC certification to migrate reserved domain name owners into the system, thus bypassing domain name auctions. BlockDNS[5] is also a blockchain-based name system designed to solve the centralization problem of DNS and the authenticity of data. BlockDNS allows users to apply for a second-level domain name. The domain name is bound to the public key of the domain name owner. The domain name owner can transfer, renew the domain name and update the domain name data.

It can be seen from the above that no one in the existing technology has proposed to realize the decentralization of domain name registration data through the domain name registration management chain.ization and the realization of transparency and standardization of domain name registration management.

IV There are many blockchain applications now. What kind of blockchain applications are good? Where can I get a clear understanding of them?

I want to know about blockchain applications. , you can refer to many books and opinions, including "Blockchain in Pictures", "Blockchain: Reshaping the Economy and the World", "New Economic Blueprint and Introduction", as well as articles from the Binance Community, including comments on the Binance Community platform Also learn more about it, its strength is awesome.

1. What is blockchain

Blockchain, as the name suggests, is composed of blocks and chains. It is a distributed data storage , point-to-point transmission, consensus mechanism, encryption algorithm and other new application models of computer technology. It is a chained data structure that combines data blocks in chronological order and is cryptographically guaranteed to be an untamperable, unforgeable, safe and trustworthy distributed ledger.

In 2008, Satoshi Nakamoto first proposed the concept of blockchain and encrypted digital currency in his paper "Bitcoin: A Peer-to-Peer Electronic Cash System". Starting from Bitcoin, blockchain has become the underlying technology of various digital currencies.

2. The working principle of blockchain:

1. Basic concepts include:
(1) Transaction: one operation will change the ledger status once , such as adding a record;
(2) Block: records transactions and status data that occurred within a specified time, which is a consensus and preservation of the current ledger status;
(3) Chain ( Chain): It is composed of blocks connected in chronological order and is a log record of the entire state change.
Understanding the working concept of blockchain, it is not difficult to understand its working principle. Suppose there is a distributed data record book. This record book only allows additions, deletions and changes. Its structure is composed of individual data records. "Blocks" are connected in series to form a linear chain (this is also the origin of the name "blockchain"). To add new data, it must be placed in a new block. The maintenance node can propose a new block. However, a certain consensus mechanism must be used to reach agreement on the final selected block.

2. Take Bitcoin as an example to see how the blockchain works.

Bitcoin blocks are divided into two parts: block header and block body.

3. Core advantages and characteristics of blockchain

1. Decentralization
Block The processes of verification, accounting, storage, maintenance and transmission of chain data are all based on the distributed system structure. There is no centralized hardware or management organization. The rights and obligations of any node are equal. The data blocks in the system are composed of Nodes with maintenance functions in the entire system are jointly maintained.
2. Open and transparent
The system is open, except for communicationIn addition to the private information of all parties being encrypted, the blockchain data is open to everyone. Anyone can query the blockchain data and develop related applications through the public interface, so the entire system information is highly transparent.
3. Security
The blockchain adopts consensus-based specifications and protocols (such as a set of open and transparent algorithms) to enable all nodes in the entire system to exchange data freely and securely in a trustless environment. , so that trust in "people" is changed to trust in machines, and any human intervention has no effect.
4. Information cannot be tampered
Once the information is verified and added to the blockchain, it will be stored permanently. Unless more than 51% of the nodes in the system (almost impossible) can be controlled at the same time, otherwise Modifications to the database on a single node are invalid, so the data stability and reliability of the blockchain are extremely high.
5. Anonymity
Since the exchange between nodes follows a fixed algorithm, the data interaction does not require trust (the program rules in the blockchain will judge whether the activity is valid by itself), so the counterparty does not need to Making the other party trust you by disclosing your identity is very helpful for the accumulation of credit.

4. Classification of Blockchains

Currently, the most mainstream classification of Blockchains is to divide Blockchains into Public Blockchains based on different participants. ), Private Blockchain and Consortium Blockchain.

1. Public chain: Anyone can participate in the use and maintenance, and can obtain effective confirmation of the blockchain. The public chain is the earliest blockchain and the most widely used blockchain at present. , typically such as the Bitcoin blockchain, the information is completely public.

If a permission mechanism is introduced, it will include private chain and alliance chain.
2. Private chain: A company or individual only uses blockchain technology and has exclusive write permission to the blockchain, and the information is not made public. At present, conservative giants (traditional finance) all want to experiment with private blockchains, and the application products of private blockchains are still being explored.
3. Consortium chain: It is a blockchain between the public chain and the virtual chain, jointly controlled by multiple organizations. The use of this chain is managed with authority and can be controlled by managers and also based on The manager's wishes are open to others.
In addition, according to the different usage scenarios and purposes of blockchain, it is divided into currency chains for the purpose of digital currency, property rights chains for the purpose of recording property rights, crowdfunding chains for the purpose of crowdfunding, etc. .

5. Analysis of specific application scenarios of blockchain

1. Information anti-counterfeiting

On May 28, Tencent CEO Ma Huateng spoke at the Guiyang Digital Expo The problem of Moutai anti-counterfeiting has been raised: the anti-counterfeiting method based on cloud-based comprehensive blockchain technology will be much more efficient than traditional anti-counterfeiting methods. Future anti-counterfeiting verification scenarios may require users to simply scan using their mobile phones, you can get a large amount of complete information based on different dimensions.

Take Moutai as an example:

Distillery address, production workshop, operating employees, inspectors, factory time, transportation vehicle information and driver information,

The vintage source of raw materials for wine, raw material suppliers, storage warehouse numbers, raw material transportation vehicles and driver information,

All information can be accurately traced, permanently recorded and cannot be tampered with.

The authenticity can be easily verified based on the above information.

2. Food safety issues

As early as November last year, Walmart had cooperated with IBM to ensure food safety by using blockchain technology to track food sources. safety and increase the circulation of food to reduce costs. For large supermarkets such as Wal-Mart, when food safety problems occurred in the past, it took several days to investigate the source of the problematic food. After using this technology, only one piece of information about the product is required. It can accurately trace the source of important information such as food origin, inspectors, suppliers, logistics and transportation, and quickly detect problems within a few minutes. Currently, products tracked using blockchain include packaging products in the United States and pork in China.

3. Information Security

Blockchain technology is promoting a revolution in information security technology. Three major security threats: man-in-the-middle attack, data tampering, and DDoS

(1) Identity protection

PKI is a common public key encryption used in various communication applications such as email, messaging applications, and websites. technology. However, since most PKI implementations rely on a centralized trusted third-party certification authority (CA) to issue, activate and store user certificates, hackers can attack PKI to fake user identities or crack encrypted information.

CertCoin is the first blockchain PKI implementation, coming from MIT, which removes the centralized certification center and uses the blockchain as a distributed ledger of domain names and public keys.

Pomcor Company: Blockchain PKI implementation path: retain the certification center and use the blockchain to store hash values ​​of issued and activated certificates. Users can verify the authenticity of certificates through decentralized and transparent sources, while also improving network access performance through local authentication of keys and signatures based on blockchain copies.

(2) Data integrity protection

GuardTime has developed a keyless signature architecture (KSI) based on blockchain technology to replace key-based data authentication technology. KSI stores hashes of the original data and files on the blockchain, runs hashing algorithms to verify other copies, and compares the results with the data stored on the blockchain. Any tampering with the data will be quickly detected because the original hash table is stored on millions of nodes.

(3) Protection of critical infrastructure

The "Achilles' heel" of the Internet, DDoS has entered the TB era, and DDoS is still the easiest way for hackers to defeat large targets at low cost. weapons, DNS services are the primary target for hackers to carry out large-scale damage, but blockchain technology is expected to fundamentally solve it.

The distributed storage of blockchain makes hacker attacks lose focus. Nebulis is developing a distributed DNS system using the Ethereum blockchain and the InterPlanetary Internet File System (IPFS, a distributed alternative to HTTP product) to register and resolve domain names. The biggest weakness of DNS is caching. Caching makes DDoS attacks possible and is also the bane of centralized governments censoring social networks and manipulating DNS registrations. A highly transparent, distributed DNS system can effectively prevent any entity, including the government, from manipulating records.

IV. Financial Industry

(1) Digital Currency: Improving the convenience of currency issuance and use

For example, foreign Bitcoin and Ethereum, our country currently There are Nuo Compao and so on.

From the use of physical transactions, to physical currency and credit currency, to the rise of the Bitcoin network, more people are aware of the distributed ledger blockchain technology behind it, and gradually outside of digital currency applied in many scenarios.

(2) Cross-border payment and settlement: realize point-to-point transactions and reduce intermediate costs

Transfer and payment. At present, the most mature application of blockchain technology is payment and transfer. Blockchain technology can avoid complicated systems, save the process of inter-bank reconciliation and review, and speed up settlement; using virtual currency does not require the intervention of a clearing house, reducing transaction fee. The clearing procedures of each country are different. It takes 2 or 3 days for a single remittance to arrive, which is inefficient and accounts for a large proportion of funds in transit. No longer going through a third party, point-to-point payment is formed through blockchain technology. Eliminating the need for third-party institutions, you can make payments throughout the day, receive money in real time, quickly withdraw cash, and reduce hidden costs, helping to avoid financial risks. It is timely and convenient.

(3) Bills and supply chain financial business: reduce human intervention, reduce costs and operational risks

Point-to-point value transfer, physical bills or central system for control and verification; intermediary will be eliminated and human intervention reduced. Improved efficiency, smoother financing channels, lower risks, and benefits for all parties.

(4) Securities issuance and trading: realize quasi-real-time asset transfer and accelerate transaction clearing speed

The application of blockchain technology can make the securities trading process simpler, more transparent and faster , Reduce IT systems with repetitive functions and improve the efficiency of market operations. For stocks, blockchain can eliminate paper and pen or spreadsheet records, reduce human errors in transactions, and improve the transparency and traceability of trading platforms. Citi and Nasdaq collaborate to advance blockchain applications.

(5) Customer credit reporting and anti-fraud: reduce legal compliance costs and prevent financial crimes

Customer information and transaction records recorded in the blockchain help banks identify Abnormal transactions and effectively prevent fraud. The technical characteristics of blockchain can change the existing credit reporting system. When banks conduct "know your customer" (KYC), the data of customers with bad records will be stored in the district.in the blockchain.

Equity crowdfunding: Equity crowdfunding based on blockchain technology can achieve decentralized trust and investors’ returns are guaranteed.

5. Supply chain management

Distributed ledger system, participants track the ownership of assets throughout the process, and can be used to track auto parts when moving between countries and factories.

Toyota is developing blockchain technology solutions for its core parts supply chain operations. Using a large amount of data helps Toyota more efficiently ensure the accuracy of recorded data and can also help manage the supply chain. At the same time, the blockchain supply chain can control warranty, repair goods-related costs and specifications through smart contracts, and transactions throughout the product life cycle are irrevocable.

The shipping industry’s first public solution, deployed by Maritime Transport International (MTI), uses blockchain supply chain technology to share Verified Gross Mass (VGM) information for shipping containers. Information about container VGM is important to ensure ships are properly stowed and to prevent accidents at sea and in ports. VGM data is stored on the blockchain supply chain, providing a permanent record for port officials, shipping companies, shippers and cargo owners. This replaces cumbersome logs, spreadsheets, data brokers and private databases.

Logistics Integrity System Wagonbang Wagonbang launched a blockchain-based financial solution for logistics enterprises, aiming to provide enterprises with reliable financial services. It can not only help drivers solve the problem of loan difficulty, but also change the current situation of lack of integrity in the industry and help build a logistics integrity system. Help build the identity chain of logistics companies and create a trusted data ecosystem for logistics companies. Using a transparent, supervisory, and traceable algorithm model, we screen reliable companies that need financial support and provide them with financial services. On the other hand, at the technical level, various law enforcement departments are linked to jointly punish dishonest companies.

6. Government management

(1) Election

Based on the characteristics of blockchain technology and considering the shortcomings of current election technology, we will build an open source , Blockchain applications for elections, voting and lottery, we call it ElectionChain. We hope to optimize election and voting technology to make voting more open and transparent, reduce human manipulation, and allow voters to verify their election results.

Including identity authentication, multi-chain system, flash investment protocol, consensus algorithm EDPOS, privacy protection, voting mechanism design, decentralized ELC rental market, storage solutions, smart contracts, etc.

(2) Government services

Aiming to realize an e-government digital ecosystem based on blockchain technology and provide citizens with government services and an automated mechanism for the business of various government departments, it must be All areas of national government affairs are combined to form a common information space, including government agencies, economic data, financial transactions and social fields. This ecosystem should also include registration authorities and corresponding software for building smart contract-based applications for government agencies, enterprises and public users.applications and platforms.

VI How to apply blockchain How to apply blockchain

1. Financial field:
Blockchain in international exchange, letters of credit, equity registration and stock exchanges It has potential huge application value in other financial fields. The application of blockchain technology in the financial industry can eliminate the need for third-party intermediaries and achieve direct point-to-point connection, thereby greatly reducing costs and quickly completing transaction payments.
2. Internet of Things and Logistics Fields:
Blockchain can also be naturally combined in the Internet of Things and logistics fields. Through blockchain, logistics costs can be reduced, the production and delivery process of items can be traced, and the efficiency of supply chain management can be improved. This field is considered a promising application direction of blockchain.
3. Public service field:
Blockchain is closely related to people’s production and life in public management, energy, transportation and other fields. However, the centralized nature of these fields also brings some problems. Blockchain can be used chain to transform. The decentralized, fully distributed DNS service provided by the blockchain can realize domain name query and resolution through point-to-point data transmission services between various nodes in the network, and can be used to ensure that the operating system and firmware of an important infrastructure are not Tampered, you can monitor the status and integrity of the software, detect bad tampering, and ensure that the data transmitted by systems using IoT technology has not been tampered with.
4. Digital copyright field:
Through blockchain technology, works can be authenticated, proving the existence of text, video, audio and other works, and ensuring the authenticity and uniqueness of ownership. After the rights of the work are confirmed on the blockchain, subsequent transactions will be recorded in real time, realizing the full life cycle management of digital copyright and also serving as a technical guarantee in judicial evidence collection. For example, MineLabs, a startup company in New York, USA, has developed a blockchain-based metadata protocol. This system called Mediachain uses the IPFS file system to realize copyright protection of digital works, mainly for copyright protection applications of digital pictures.
5. Insurance field:
In terms of insurance claims, insurance institutions are responsible for fund collection, investment, and claims settlement, and often have high management and operating costs. Through the application of smart contracts, Can Thanh Orange does not require the policy holder to apply or the insurance company to approve it. As long as the claim settlement conditions are triggered, the policy will realize automatic claim settlement. A typical application case is LenderBot, which was launched in 2016 by the blockchain company Stratumn, Deloitte and the payment service provider Lemonway. It allows people to register customized micro-insurance products through the chat function of Facebook Messenger to provide insurance services between individuals. The high-value items exchanged are insured, and the blockchain replaces the third-party role in the loan contract.
6. Public welfare field:
The data stored on the blockchain is highly reliable and cannot be tampered with, so it is naturally suitable for use in social welfare scenarios. Relevant information in the public welfare process, such as donation projects, fundraising details, fund flows, and recipientsFeedback, etc., can be stored on the blockchain and transparently and publicly disclosed conditionally to facilitate social supervision.

Ⅶ What is the current market situation of blockchain-related domain names
