① What are the application prospects of blockchain?

The application prospects of blockchain are mainly in the financial field, Internet of Things and logistics, public services, digital copyright, and insurance. field.

1. Blockchain has huge potential application prospects in financial fields such as international exchange, letters of credit, equity registration and stock exchanges. The application of blockchain technology in the financial industry can eliminate the need for third-party intermediaries and achieve direct point-to-point connection.

2. Blockchain can also be naturally combined in the Internet of Things and logistics fields. This field is considered to be a promising application direction of blockchain. Establishing credit resources in the blockchain can double improve the security of transactions and improve the convenience of IoT transactions. Save time and cost for smart logistics model applications.

3. Blockchain is closely related to people’s production and life in public management, energy, transportation and other fields. The decentralized and 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.

4. 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 full life cycle management of digital copyright, and can also be used as a technical guarantee in judicial evidence collection.

5. 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, there is no need for the policy holder to apply or the insurance company to approve it. As long as the claim settlement conditions are triggered, the insurance policy can automatically settle claims.

Core Technology of Blockchain

1. Consensus Mechanism , through the voting of special nodes, the verification and confirmation of the transaction can be completed in a very short time; for a transaction, if several nodes with unrelated interests can reach a consensus, it can be considered that the entire network can also reach a consensus on it. The goal of the blockchain consensus mechanism is to enable all honest nodes to maintain a consistent view of the blockchain.

2. Asymmetric encryption requires two keys for encryption and decryption. These two keys are the public key and the private key. The public key corresponds to the private key. When the public key is used in the encryption process of data, it can only be decrypted by using the corresponding private key. On the contrary, when the private key is used in encrypting the data, only the corresponding private key can be used to decrypt the data. Only the corresponding public key can be decrypted.

② What is the difference between blockchain, virtual currency and gambling

Blockchain is a distributed irreversible ledger technology
Virtual currency is a network currency
Gambling is a speculative behavior

③ What is the blockchain and can it be invested in?

What is the blockchain and can it be invested in?

Blockchain technology is an emerging concept after the introduction of the Internet concept. It mainly solves the information asymmetry in society and provides decentralized services. Give an example to explain what blockchain technology is:

Usually we deposit cash into the bank. Every time we withdraw money, the transfer must go through the bank system to complete. So if we use blockchain technology To solve this problem, then our money does not need to be placed in the bank. When transferring money to others, we only need to transmit data on the chain. The transfer record data will be recorded by the entire network, and the consumption path of the amount can be found at any time. , there is no need to go through any intermediary to complete the intermediate recording.

This is just one of the scenarios where blockchain technology is applied. At present, the payment industry, gaming industry, lottery gambling industry, etc. are the most widely used blockchain technology.

In the nascent stage of the development of blockchain technology, many investors will naturally see the development potential and prepare to invest in blockchain. So how to invest in blockchain? Everyone knows that with the emergence of blockchain technology, digital currency will be generated, and the circulation of digital currency will generate value. Ordinary people can invest in blockchain by purchasing digital currency. Common digital currencies include Bitcoin, Ethereum, Yuzi, etc. However, the risk is extremely high. The return is much higher than that of stock investment, but the risk is also several times higher. Therefore, when investing in blockchain, the choice of digital currency is also very important. For novice investors, it is recommended to choose mainstream currencies, such as Bitcoin, Ethereum and Ripple. Their value has been basically recognized, they have a consensus mechanism, and the price will not drop significantly. However, the corresponding blockchain technology is still the best. Ethereum.

For professional risk control investors, you can choose to invest in blockchain companies, taking a fancy to their long-term value and tokens. Nowadays, blockchain companies will issue coins, which are so-called digital currencies. However, their value is zero and they have no actual circulation significance. Therefore, if you choose to invest in a blockchain company, you still need to see clearly the content of the company's projects, whether they can be truly implemented, and how much potential they have for changing human life in the future.

④ Is the blockchain lottery project a scam?

Definitely. Online lottery sales have long been banned by the state, and all lottery tickets sold online are now virtual. They will first let you win a small amount of money virtually, and then ask you to increase your bets. In the end, you will lose all your money. Do not participate.

⑤ What exactly is blockchain? Which blockchains have physical applications

What is blockchain?

Official definition: Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission consensus mechanism encryption algorithm, etc. The so-called consensus mechanism is a mathematical algorithm that establishes trust and obtains rights and interests between different nodes in the blockchain system.

Vernacular understanding: A block is to package all the data generated within a time period in chronological order. Generally, the length of a block is 10 minutes, which means that within 10 minutes all the data on the networkThe Internet data on the Internet is packed into a complete package. This complete data package is called a block. The blockchain links these data packages in order to form a structure, and cryptographically ensures that it cannot be tampered with or forged. Forming a distributed ledger, this is the blockchain.

It seems that everyone has a preliminary knowledge and understanding of the blockchain. So whether the blockchain has any practical application in daily life, the answer is yes, the current practical application There are mainly the following aspects. Of course, I may not know some of them. Friends are welcome to leave messages to add.

Financial Industry

Blockchain should be used the most in the financial industry.

For example, in May 2017, OMG (Omise Coin) announced that it would cooperate with Alipay to launch an electronic wallet, integrating the "Alipay" payment solution into its own payment service suite to help local electronics in Thailand. Business merchants accept online payment transactions from Chinese tourists.

Another example is PPT, which is a financial transaction system for bills based on blockchain.

Gaming

The gambling industry entered the blockchain probably last year. Why does gambling favor blockchain? Because blockchain provides a relatively fair betting system. Why? It is relatively fair. As can be seen from the previous introduction, the blockchain cannot be tampered with or forged.

For example, WICC (WikiChain) can realize rich application scenarios such as asset issuance, betting applications, copyright traceability, mutual insurance, decentralized exchanges, and cross-border settlement.

For example, the STX (King of Fighters Token) stox application is designed to provide the full functionality of a prediction market application without the need for any central server. Prediction markets require functions such as event planning, market production, providing information and analysis to traders, reporting event results, and of course collection and payment.

I believe that if the current lottery industry is built on the blockchain, people will become more and more enthusiastic about buying, because there are too many insider tips that make people give up.

Internet of Things

The Internet of Things still has many applications on the blockchain, because the traceability and immediacy of blocks are very suitable for this industry.

For example, DATA is the concept of the Internet of Things. It is a decentralized p2p network. Data sources can connect to any node in the entire network, then publish data, and the network will immediately send it to subscribers. Horizontal scalability is achieved through sharding pattern. This timeliness and accuracy are very important in IoT applications.

Game industry

For example, GTC (G coin) is a decentralized digital asset based on Ethereum erc20 issued by Game Global. G coin is committed to becoming a universal number in the global game industry. Monetary standards.

For example, MANA is a distributed shared virtual platform. On this platform, users can browse and discover content and interact with other people and entities. userIt is also possible to claim ownership of virtual territories through a blockchain-based land ledger. The territory is demarcated by rectangular coordinates (x, y), and its owner can decide the content published on the territory, including static 3D scenes to interactive systems such as games.

There are many other industries. The emperor did not list them one by one, but listed a few representative ones. What is the purpose? It shows that the blockchain is definitely not just a currency transaction, it is a real implementation project, and it is a product of the changes of the times with real practical uses.

The development of human society is actually like the blockchain, it is irreversible and unstoppable. As far as I feel, the blockchain will enter thousands of households sooner or later. Regardless of whether it is bull or bear, hold it in your hands. Value coins and Flush have started quoting digital currencies, which shows that society is accepting it step by step. The power of social development cannot be blocked by any country or person.

⑥ 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 a sequential manner 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. A linear chain formed by "blocks" connected in series (this is also the origin of the name "blockchain"). To add new data, it must be placed in a new block and maintainedNodes can propose a new block, but a certain consensus mechanism must be used to agree 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. In addition to the private information of the transaction parties being encrypted, the blockchain data is open to everyone, and anyone can query the blockchain through the public interface. Data and development related applications, 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. Alliance 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 the manager or according to the manager. Willingness to be 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. In future anti-counterfeiting verification scenarios, users may only need to perform a simple scan with their mobile phone to obtain 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. User authentication certificates through decentralized and transparent provenanceauthenticity, 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. As a weapon, 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 tradingYi: Realizing quasi-real-time asset transfer and accelerating transaction clearing speed

The application of blockchain technology can make the securities trading process more concise, transparent and fast, 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 perform "know your customer" (KYC), the data of customers with bad records will be stored 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 want to optimize elections and votingTechnology makes voting more open and transparent, reduces human manipulation, and allows 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 registries and corresponding software for building smart contract-based applications and platforms for government agencies, businesses and public users.

⑦ How do blockchain projects make profits

How do blockchain projects make profits? Three areas where blockchain has had a chain reaction

The research and development of blockchain has been going on for several years. I believe that the people who initially did research and development also wanted to make money later, just like we want to use Like mobile apps, none of them are completely free to use. They will always make you pay in various ways. Of course, the same is true for blockchain. Otherwise, how can you recover so much money invested in early research and development? Well, it is recovered through providing services to people in the later stage and other ways.
In fact, many people know the principle, but unfortunately they do not understand the technology or English.
So how do they compete with those who have advantages?
Even though many people know that blockchain is a once-in-a-lifetime opportunity, they feel that the threshold for the blockchain industry is very high, as if there are many The invisible mountain makes them insurmountable, but in fact the opportunities of blockchain belong to all industries and everyone.
There are many ways that blockchain technology can be used to make money. Next, I will give you a brief introduction to the ways in which blockchain can make money:
1. Make money by speculating on coins:
In fact, this method is a relatively poor way to make money. It is equivalent to buying welfare lottery tickets. All people who speculate in coins will have a mentality of getting rich overnight, but for these people who want to learn It is still difficult to get started and obtain effective information resources.
People who speculate in currency need to know how to buy better, which one to buy is more valuable, and they must always pay attention to the trend of the entire currency environment. Therefore, speculating in currency is not a simple and easy thing to do. You need to learn There are still many things.
2. Make money through blockchain projects:
Those who really do projects not only lock their own tokens, but also spend a lot of manpower and material resources to promote, build and operate the community to make their own projects Become more popular and achieve their dreams.
Through the blockchain, a group of strangers can complete a great project togetherjobs and projects.
They use money to drive people to help promote and motivate the community, but in the new production chain relationship, the community not only occupies a large dominant position, but also the distribution of their incentives is the largest, which is why many people have always emphasized the community. Here's why.
In fact, there are some people who specialize in this kind of community activities to help projects, media, and the community operations of some big figures. In addition to getting some money in return, they can also get some high-quality resources, information, and awareness. etc.
3. Make money through exchanges:
Some people may think that can you still make money from exchanges as the top of the food chain?
In fact, exchanges are essentially a service industry. , it also needs more publicity and promotion to let more people know about it, and now the market competition is becoming more and more fierce, and many exchanges want to obtain more users through various channels.
The exchange’s income source mainly comes from commissions obtained from registration. Don't underestimate this source of income. Overall, this will be a large business income, and the amount of the commission is also considerable.
Some exchanges have begun to establish commission systems to make their prospects of making money better.
4. Make money through wool:
There are many projects now. In order to win customers, there are various airdrops, various invitations to register and give coins, etc.
A good project. If you can use multiple accounts to register and invite each other to earn coins, it would be really impressive. The day before yesterday, I saw nearly 300,000 CET, which was sold for around 1 yuan, which was 300,000. .
5. Make money through games:
Nowadays, there are more and more blockchain games. NW is a game that allows people who joined early to make a lot of money. Now there are fish, super miners, etc. I entered yesterday. I played around a bit and caught some Bitcoins, but it took a lot of time.
At present, blockchain technology is currently making money through these ways. However, as its technology develops and matures, it is difficult to predict what the situation will be like. There may be no way to make money. It will change more and more.
As we all know, blockchain is being promoted to many industries. Blockchain technology is scalable. It can be used to create a global ledger account that stores data on thousands of servers. This information is available to everyone in real time.
This blockchain is virtually unbreakable. Every transaction has a timestamp that cannot be changed. It is already having an impact on industries where efficiency matters most.
The following areas are where blockchain has already had significant ripple effects.
Logistics
Blockchain technology is changing the face of modern logistics. Fifty years ago, few businesses traded globally.
Today, it is not just the Fortune 500 companies that engage in international trade. Thanks to cloud technology, innovative fintech and e-commerce solutions, it is now easier than ever to discover the full potential of a businessball potential.
Amazon currently has 340 million online buyers in Europe alone.
It's clear that online trading is more profitable than ever, but no matter what niche you're in, you have to watch your bottom line.
This is what blockchain does.
Blockchain makes the logistics of transporting goods from A to B more efficient. Existing technology already makes it possible to track shipments, and the data is not easily misinterpreted or tampered with.
Blockchain applications solve the issue of authenticity and add a layer of responsibility and trust to global logistics. The company saves money while customers enjoy better service. It's a win-win situation for everyone.
Healthcare
The healthcare industry is already benefiting from blockchain technology, especially in the pharmaceutical and biotech sectors, but it has the potential to do much more.
Healthcare generates huge amounts of data.
The United States has approximately 325 million U.S. citizens’ medical records. On top of that there's all kinds of information like medical research, and it's difficult to record all that data, so the system has become incredibly confusing over the years.
Blockchain is changing the face of modern health care by providing a secure third-party mechanism to store data.
86.9% of physicians now use electronic medical records, but the system remains fragmented and errors cost lives.
Blockchain unifies EMR systems, making data more accessible and easier to track across different platforms. In the long run, blockchain will have a positive effect on saving money and improving the efficiency of medical services.
Finance
Finance is probably the most well-known application of blockchain technology, as most people associate it with cryptocurrencies such as Bitcoin and Ethereum.
However, Bitcoin and blockchain are not the same thing. Bitcoin transactions are stored on a distributed ledger.
However, while governments and financial institutions remain skeptical of Bitcoin, basic blockchain technology is being adapted to reform the banking industry.
Cut
It is expected that by 2020, Goldman Sachs will use blockchain technology to eliminate additional costs, saving it approximately $6 billion per year.
Not only that blockchain will reduce the number of erroneous and fraudulent transactions, thus saving more money.
Banks have traditionally used secure databases for transactions.
Banks need to establish a secure connection to send and receive funds, which is time-consuming and expensive. Blockchain technology allows for instant transactions and no geographical restrictions.
Global payments settle in seconds instead of days.
IBM is already working on blockchain global payment solutions, so it is only a matter of time before global currency transactions enter the blockchain.

⑧Which country does win coin belong to?

WIN coin is a blockchain-based national lottery underlying system first used in a certain African country.The policies and regulations of the lottery industry in various countries around the world are different, the lottery types are diverse, and the identity requirements for users to purchase lottery tickets are also different. Winchain's SmartKYC system is a complete intelligent user identity verification system. Winchain is a national-level underlying lottery system developed by a Silicon Valley team based on a blockchain architecture. With excellent blockchain technology and leading industry resources, the team uses decentralized thinking to innovate the lottery industry and develop Winchain blockchain lottery into the standard for the world's lottery underlying system. At present, the national lottery system of an African country has decided to use the Winchain underlying lottery system to issue lottery tickets, with the goal of issuing the world's first blockchain-based lottery in August 2018.
2. The underlying lottery system of Winchain is being actively expanded in countries along the Belt and Road Initiative in Asia, Europe, and African countries. Currently, several national lottery systems have the intention to actively promote it. The team’s vision is to become the world’s leading lottery solution provider in the blockchain era.
Extended information:
1. As the underlying system of the blockchain for the global lottery market, the total number of WinToken (WIN currency) certificates is 21 billion, of which the amount that can be exchanged externally is 10.5 billion (account 50%); of the 10.5 billion (50%) held by the other part, 15% will be reserved as team rewards, 15% will be reserved for marketing and strategic cooperation, node rewards, etc., and 10% will be used for the community Construction, 10% will be used for the developer ecosystem.
2. The blockchain market is a mixed bag. WinToken (WIN currency) has a strong team and rich industry resources. It will work with companies from various countries that have joined the Winchain ecosystem to implement national blockchain lottery systems in multiple countries. According to Winchain At the three key nodes that are gradually implemented, WinToken will be separated into three stages for token exchange. Between each stage, community members will see that Winchain has made important substantive progress in the global lottery market, and will see the strength of the Winchain ecosystem and ecological projects. The goal of Winchain is to create the first killer application in the entire blockchain world in the lottery industry, which is the most suitable industry for blockchain technology.
3. The first phase: Key node in February 2018: WinToken Ecological Cooperation Company obtained a national blockchain lottery operation license in an African country, and the team has already started building part of the lottery system.
4. Winchain officially launched the first token exchange, releasing no more than 20% (including 15% of the tokens issued to the outside world, a total of 3.15 billion tokens, raising no more than 15,000 ETH; and cornerstone gifts), targeting Cornerstone Investments People and private equity institutions, the funds will be used for market docking in various countries, system development, license cooperation, strategic layout, community rewards, personnel expenses, legal expenses and unexpected expenses, etc.;
5. The second phase: approximately August 2018 Key node: jointly establish the Asian blockThe Chain Lottery Research Institute promotes blockchain technology, especially the Winchain technology system, to recognize the advantages of the lottery industry and industry cooperation; it issues the world's first national blockchain lottery. WinToken’s second token exchange event will issue 15% of the tokens to the outside world, totaling 3.15 billion tokens (so far, a total of 30% of the tokens have been issued to the outside world), targeting private equity institutions and qualified investors.
