1. What is blockchain and its application in the automotive field?

1. The decentralization, transparency and trust of blockchain technology are to solve Current problems such as user privacy leakage, poor maintenance service dispersion, and irregularities in the automotive industry have brought opportunities. The key to the application of blockchain in the automotive field lies in the construction and integration of car identity and user credit systems to create car logos, completely record key information during the manufacturing and use of cars, promote the standardization of the traditional automotive industry chain, and establish a reliable system for car companies. The service platform quality control system and optimized inventory dynamic management provide users with better repair, maintenance and second-hand car trading services. Combining car identity and personal credit, it is connected to the blockchain system and can transform the original car sharing business process. In the future, blockchain, as the underlying technology, will be combined with edge technologies such as the Internet of Things and big data to achieve safe interconnection of different smart devices, continuously improve the processing capabilities of blockchain technology, and accelerate its development in the fields of autonomous driving and intelligence. application.

3. Blockchain system information transparency, tamper-proof, and forgery can effectively solve this problem, which will have an impact on the financial Internet of Things, supply chain, government services and other fields. deep influence. Due to its transparent, reliable and traceable characteristics, blockchain technology can build a car identity and completely record the source of car parts and production processes, sales channels, use and maintenance, vehicle positioning and other data to promote into the traditional automotive industry chain. "Production, supply and marketing after market" standards. At the same time, a tamper-proof and securely encrypted user credit system can be built through the blockchain to record, store, and integrate user online transaction information and credit evaluations such as asset information, user information, and user behavior. Because the application of car retail, leasing, sharing and other scenarios is essentially an extension of the personal credit system, the blockchain system will eventually bring information such as identity, user credit and service history to owners through the blockchain system, which will be associated with car identities to improve the security of interconnection. to realize the application of blockchain autonomous driving in fields such as Internet of Vehicles and vehicle sharing.

2. Applications of blockchain

The main application scope of blockchain includes: digital currency, transaction settlement of financial assets, digital government affairs, certificate deposit and anti-counterfeiting data services and other fields . Blockchain is a database technology that links data blocks in an orderly manner. Each block is responsible for recording a file data and encrypting it to ensure that the data cannot be modified or forged.

Blockchain is essentially a distributed database system that uses cryptography technology for multi-party participation, joint maintenance, and continuous growth. It is also called a distributed shared ledger. Each page in the shared ledger is a block, and each block is filled with transaction records. The anonymity, decentralization, openness, transparency, and non-tamperability of blockchain technology make it highly favored by enterprises and has gained More extensive application attempts.

Blockchain application scope 1. Financial field

Blockchain can provide a trust mechanism and has the potential to change the financial infrastructure. Various financial assets such as equity, bonds, bills, warehouse receipts,Fund shares, etc. can be integrated into the blockchain technology system and become digital assets on the chain, which can be stored, transferred and traded on the blockchain.

The decentralization of blockchain technology can reduce transaction costs and make financial transactions more convenient, intuitive and secure. The combination of blockchain technology and the financial industry will inevitably create more and more business models, service scenarios, business processes and financial products, thereby bringing more impact to the development of financial markets, financial institutions, financial services and financial formats. . With the improvement of blockchain technology and the combination of blockchain technology with other financial technologies, blockchain technology will gradually adapt to the application of large-scale financial scenarios.

2. Public service field

Traditional public services rely on limited data dimensions, and the information obtained may not be comprehensive enough and have a certain lag. The non-tamperable nature of the blockchain makes the digital certification on the chain highly credible. It can be used to establish new authentication mechanisms in the fields of property rights, notarization and public welfare, and improve the management level of public services.

Relevant information in the public welfare process, such as donation projects, fundraising details, fund flows, recipient feedback, etc., can be stored on the blockchain to meet the privacy protection of project participants and other relevant laws and regulations. Under the premise of requirements, public disclosure will be made conditionally to facilitate public and social supervision.

3. Information security field

Using the traceability and non-tampering characteristics of blockchain, we can ensure the authenticity of data sources and ensure the non-forgery of data. Blockchain technology will fundamentally change information Security issues of the propagation path.

Blockchain is reflected in the following three points in the field of information security:

User identity authentication protects data integrity and effectively prevents DDoS attacks

The distributed storage architecture of blockchain will make Hackers are at a loss as to what to do. Some companies have begun to develop a distributed Internet domain name system based on blockchain to eliminate the root cause of the current DNS registration shortcomings and make the network system cleaner and more transparent.

4. Internet of Things field

Blockchain + Internet of Things can allow each device on the Internet of Things to operate independently, and the information generated by the entire network can be protected through smart contracts in the blockchain.

Security: Traditional IoT devices are highly vulnerable to attacks, data loss and maintenance costs are high. Typical information security risk issues for IoT devices include low firmware versions, lack of security patches, permission loopholes, too many device network ports, and unencrypted information transmission. The blockchain's consensus mechanism for network-wide node verification, asymmetric encryption technology and distributed data storage will significantly reduce the risk of hacker attacks.

Trustability: The traditional Internet of Things is managed and controlled by a centralized cloud server. Due to the security of the device and the opacity of the centralized server, it is difficult to effectively protect user privacy data. The blockchain is a distributed account book. Each block is interconnected and has its own independent working ability, ensuring that the information on the chain will not be tampered with at will. Therefore, distributed ledgers can provide trust, ownership records, transparency and communication support for the Internet of Things.hold.

Effectiveness: Limited by cloud services and maintenance costs, the Internet of Things is difficult to achieve large-scale commercial use. The traditional Internet of Things realizes communication between things through centralized cloud servers. The disadvantage of this model is that as the number of access devices increases, the server faces more load, requiring enterprises to invest a lot of money to maintain the normal operation of the IoT system.

Blockchain technology can directly realize point-to-point transactions, omitting the labor expenditure of other intermediaries or personnel, which can effectively reduce the costs incurred by third-party services and maximize benefits.

5. Supply chain field

The supply chain consists of many participating entities, with a large amount of interaction and collaboration. Information is discretely stored in their own systems, lacking transparency. The lack of smooth information makes it difficult for various participating entities to accurately understand the real-time status and existing problems of related matters, affecting the collaborative efficiency of the supply chain. When disputes arise between parties, it is time-consuming and laborious to provide evidence and pursue accountability.

Blockchain can make data open and transparent among various entities, thereby forming a complete, smooth, and non-tamperable information flow throughout the entire supply chain. This can ensure that all entities promptly discover problems arising during the operation of the supply chain system and find targeted solutions, thus improving the overall efficiency of supply chain management.

6. Automotive Industry

Last year announced a partnership using blockchain to build a proof of concept to streamline the car rental process and build it into a “click, sign up, and drive” process. Future customers choose what they want The rented car enters the public ledger of the blockchain; then, sitting in the driver's seat, the customer signs the rental agreement and insurance policy, and the blockchain updates the information simultaneously. This is not an imagination, for car sales and car registration That said, this type of process may also develop into reality.

7. Stock Trading

For many years, many companies have worked to make the process of buying, selling, and trading stocks easy. Emerging Blockchain Chain startups believe that blockchain technology can make this process more secure and automated than any previous solution. At the same time, blockchain startup Chain is working with Nasdaq to enable private companies through blockchain. Equity transfer

8. Government management

Government information, project bidding and other information are open and transparent. Government work is usually subject to public attention and supervision. Since blockchain technology can ensure the transparency and immutability of information, it is very important to the government. The implementation of transparent management plays a great role. There is a certain degree of information opacity in government project bidding, and enterprises also have the risk of information leakage during the sealed bidding process. Blockchain can ensure that bidding information cannot be tampered with and can ensure the transparency of information nature, forming a common trust among competitors who do not trust each other. It can also arrange subsequent smart contracts through the blockchain to ensure the construction progress of the project and prevent the growth of corruption to a certain extent.

There are many more applications of blockchain technology, and this is just a fulcrum of blockchain applications. In the future, blockchain technology will be applied everywhere

3. BlockchainHow blockchain is used in industries

Blockchain can be applied to many industries and can bring great changes to the industry.
1. Payment and cash transactions
Blockchain uses its decentralized advantage to create a more direct payment flow for payments and cash transactions. It can be domestic or cross-border and does not require intermediaries. Super low rates and almost instantaneous speeds for payment.
2. Banking Industry
Essentially, a bank is a secure storage warehouse and value exchange center, and blockchain, as a digital, secure and tamper-proof general ledger, can achieve the same effect.
3. Games
The core value of the blockchain application game field: returning game rights to game players. The technical features of blockchain technology such as decentralization, smart contracts, and asset transactions can well solve the problem of privacy leakage of game data and user data in the current gaming industry, promote the preservation of the value of virtual digital currencies in games, and realize the development of users and games. Fair value sharing through channels.
4. Internet of Things
As an anonymous and decentralized peer-to-peer remote sensing technology, blockchain can become a public account book for a large number of devices, and they will no longer need to have a centralized routing between them. Intermediate traffic. Without a central control system to authenticate, devices will be able to anonymously transmit between themselves and manage software updates, errors, or energy management.
5. Supply chain finance
Blockchain can alleviate the problem of information asymmetry and is very suitable for the development of supply chain finance. In the supply chain, goods are accompanied by monetary payment activities from sellers to buyers. In the context of high credit costs and corporate cash flow needs, financial services companies provide goods transfer and payment protection. The characteristics of supply chain traceability, anti-counterfeiting, transaction authenticity, and timely liquidation will solve many pain points in the existing trade finance network and shape the infrastructure of the next generation of supply chain finance.
6. Copyright protection
In the blockchain technology environment, every copyright transaction will produce an irreversible transaction record, which means that it includes an idea, story, script or character. Once recorded on the blockchain, the asset will always be tracked even if ownership is exchanged, transferred, sold, etc., thus solving copyright issues.
7. Cross-border payment
Cross-border payment involves multiple currencies, has exchange rate issues, cumbersome processes, and long settlement cycles: traditional cross-border payments are basically non-real-time, and banks conduct transactions in batches at the end of the day. Processing, usually a transaction takes more than 24 hours to complete; some banks' cross-border payments appear to be real-time, but in fact, the receiving bank advances a certain amount based on the credit of the remitting bank, and then repays it at the end of the day. The business processing speed is slow for fund clearing and reconciliation.
8. Cloud Computing
The core value of blockchain application in the field of cloud computing: Promote the construction process of public trust infrastructure.
The my country Academy of Information and Communications Technology believes that the combination of blockchain and cloud is also necessaryNatural trend. There are two ways to combine blockchain and cloud. One is that the blockchain is on the cloud, and the other is that the blockchain is in the cloud.
9. File Storage
The decentralization of blockchain can store data in a safe, high-performance and cheap way, spreading the data across many nodes. As for data security, the blockchain approach means that each file is shredded and encrypted using your own key, then spread across the network until you are ready to use the file again and need to retrieve it. , the files are decrypted and quickly and seamlessly reassembled.
There are too many usage scenarios for blockchain. Here are just some of them. More industries can read related books.

4. In the new retail era, how to use blockchain technology to create better customer marketing relationships

Author | Campbell R. Harvey

Source | Shiji Business Review (ID: efuture555)

In the marketing and advertising industry, blockchain technology has more important application significance. However, "CMO 》Survey data shows that only 8% of companies believe that blockchain technology plays a medium or important role in marketing.

Although the blockchain concept has received a lot of hype, the obvious result is that blockchain technology is not well understood. Such "conceptual hype + lack of in-depth understanding" has caused certain obstacles to the in-depth application of blockchain technology, causing marketers to adopt a "hesitant and wait-and-see" attitude towards this technology.

Blockchain technology has the characteristics of transparency, stability and security, which makes this technology widely used in supply chain management (SCM, SupplierChainManagement), smart contracts (Smart Contracts), and financial reporting (Financial Reporting). It has reliable and trustworthy advantages in information management such as IoT (Internet of Things), private medical treatment, and even power grids. At the same time, the data transfer model of blockchain technology greatly reduces transaction costs, achieves verification and effective exchange of ownership, and opens the door to real-time micropayments. This information exchange model reduces payment friction, some intermediaries and intermediate links that make a living disappear, and it becomes possible for consumers to own and control personal information. All of the above allow us to see the disruptive potential of blockchain technology in information management, transactions, marketing and other fields.

Today, financial transactions have considerable transaction costs. Retailers need to pay a 3% payment processing fee to credit card companies (Translator's Note: 3% is the US processing fee standard), and payment processing fees at gas stations are even higher. Sellers selling on eBay and Shopify are required toWe are responsible for payment fees and transaction fees, as well as transaction fees for PayPal payments, etc. All of these fees add to the cost of goods and are often passed on to consumers. Therefore, with the widespread use of credit cards and debit cards, many merchants have set consumption limits to avoid loss of profits caused by excessive fees.

Blockchain technology will significantly reduce financial transaction costs, even approaching "zero transaction costs." Even small transactions will enjoy this profit. In the financial field, financial giants such as Mastercard and Visa are already using blockchain technology to handle local currency remittance business. The entire process is safe and transparent, which brings more choices and benefits to merchants. Cost comparison opportunities instead of relying solely on credit card transactions.

In the field of marketing and advertising, blockchain technology also has a profound impact. Currently, marketers are already using shared information purchased from third-party social media (such as Facebook) to obtain customer marketing data. This move undoubtedly illustrates the marketing value of data and also points to the trend and potential of digital marketing.

However, using blockchain technology, merchants can use micropayments to incentivize consumers to share personal information without the need for intermediary merchants. For example:

A grocery chain can pay consumers $1 for installing their APP;

If consumers agree to enable location tracking, they can get another $1 Rewards;

If consumers open the APP "1 time per day" and spend at least 1 minute on it, retailers can pay them a few cents or store points to reward customers for their loyalty. Spend.

During this period, merchants will push promotions and special offers to consumers.

In fact, consumer customization opens up some legitimate marketing mechanisms, such as providing personalized marketing or prices. This is one of the main values ​​of consumers voluntarily providing various data. This method of marketing estimation derived from real consumer data will not only reduce the risk of fraud caused by anonymous promotions, but also reduce the various risks of promoting APPs due to incomplete and inaccurate consumer information. Application troubles.

The same method as the above method of promoting the use of APP can also be used for "smart contract" (a virtual agreement that does not require a middleman to confirm, audit and verify identity due to the support of blockchain technology) marketing middle. Based on the support of blockchain technology, consumers will activate this "smart contract" when they subscribe to emails or bookmark registration reward programs. After that, whenever consumers interact with emails or advertisements, small incentives will be automatically saved. into consumers’ wallets. This brings us to our next topic.

A similar pattern canIt is used in website promotion advertising business, that is, by motivating consumers through compensation to drive page views for each advertising page.

In 2016, a study released by HubSpot showed that most Internet users do not like pop-up advertising windows and mobile window ads, believing that online advertising seriously interferes with vision and has certain intrusive and damaging negative effects. For this reason, more and more users are installing ad blocking tools. This widespread trend of distaste has had significant punitive consequences for the advertising industry. It is estimated that ad blocking will cost publishers a whopping $35 billion in lost revenue by 2020.

With the support of blockchain technology, marketers can rethink their advertising, marketing promotion and revenue models, that is, consumers who pay attention to marketing and advertising can directly pay them "small incentives" "Of course, this method will also get rid of the middle layer of advertising distribution, Google or Facebook.

It is believed that the “duopoly” of Google or Facebook in the Internet and digital advertising will soon be threatened by the application of blockchain technology. Although keyword-based search will not completely disappear, its advantages will no longer exist. Ultimately, individuals will take control of their own private online profiles and manage their own social networks.

With the help of blockchain technology, companies can bypass some of the current social media “giants” by interacting directly with consumers and share the rewards of browsing ads with consumers. In 2016, Google reportedly generated an average of $73 in revenue per active user through advertising. Of course, $73 is just the average return for more than 1 billion active users, and we can reasonably estimate that the revenue Google brings to some highly valued people will be far more than $1,000. Just imagine, when companies use blockchain technology to implement "voluntary browsing advertising" and deliver effective product consumption value to consumers, how great the marketing effect will be?

With the help of blockchain technology, advertising delivery and the degree of consumer participation can also be confirmed to avoid excessive advertising and the abuse of email advertising. Because excessive advertisements and flooding of email advertisements will not only make consumers bored and lose motivation to purchase, but will also aggravate consumers and create resentment, thereby blocking advertisements. For example, consumers who have already purchased the product will not be willing to receive it anymore. Any advertising placed by the Company.

Blockchain technology can also be used to verify the source of marketing information. Micropayments will effectively destroy large-scale phishing spam emails, weaken the interference of ineffective marketing on people, and purify the Email environment.

Approximately 135 billion spam emails are sent to users every day, accounting for 48% of all emails sent. In theseWith only one reply for every 12.5 million emails sent that are considered “junk,” the waste and disruption are staggering.

Using blockchain technology, as long as the recipient is paid a small marketing fee, spam can be filtered or blocked through these small marketing costs. With the help of these marketing costs, companies can help identify the target emails. Marketing or trading to consumer groups with independent wishes.

A similar situation is that on the Internet, every time a user clicks on a link, a small micropayment transaction may be generated. In most cases, users only need to pay a small fee, for example, it only costs one cent to read a news article. This kind of micropayment will be a powerful weapon in defeating "denial of service attacks". (Translator's Note: Denial of service attacks, referred to as Dos attack. Dos attack is a type of network attack. This attack has always been a problem that cannot be reasonably solved. For example, an attacker recruits a robot to attack a website, Sending millions of requests causes the website to crash due to full cache, slow response or even outage).

Blockchain technology can also prevent robots from setting up false media accounts, sending a large amount of false information to users, and stealing the online advertising revenue of big brands. Online authenticity is indeed baked into blockchain technology.

Keybase.io is a company dedicated to solving the problem of social media fraud, using blockchain technology to allow individuals to prove that they are the legitimate owners of various social media accounts. This makes marketing impact easier to track and marketing spend easier to demonstrate, both of which represent major breakthroughs for the marketing industry.

As of 2016, fraudulent or deceptive display advertising resulted in a loss of $7.6 billion, and this loss accounted for 56% of total display advertising revenue. In the next few years, this number is expected to increase. will rise to $10.9 billion.

Using blockchain technology to track advertising display activities, marketing organizations can monitor the execution of the entire automated advertising campaign to ensure that marketing support is used to promote return on investment (ROI), and can directly quantify and analyze marketing The input and output of activities generated by each user and each email.

By associating small marketing behaviors with micropayments, blockchain technology solves these attribution problems that have plagued marketers in industry operations and management for decades.

In addition, ordinary people who create popular new media content, such as some highly sought-after viral videos or social posts, can receive "rewards" every time they are clicked , this will all be attributed to "blockchain technology". But the current situation is that unless their work is published on a subscription-based online platform or channel, they are not paid a penny.

In all of thisIn some blockchain application scenarios, content creators have the right to create and manage their own successful works.

Coupit is both a cryptocurrency (Coupit Coin) platform and an open market where businesses and individuals can sell their products and services. The difference is that Coupit is an e-commerce platform powered by blockchain technology, and Coupit is preparing to maximize the use of blockchain technology to improve the impact of its marketing content.

Based on the support of blockchain technology, the company's marketers can intervene in the development process of consumer loyalty programs and group buying alliance programs. Consumers can exchange their own rewards and offers with each other, and marketers can easily differentiate between dormant and loyal customers. This visible, transparent, and easy-to-operate means helps marketers create personalized marketing prices and promotions for customers, thereby expanding their marketing effectiveness.

Even if aggregator analysis or intermediary analysis is necessary, micropayments will allow businesses to bypass ad blocking tools, and individuals will have control over the amount of personal information they share and will directly receive ad views. With the rewards coming, many privacy issues will also be completely solved due to legal protection.

Take the Brave browser as an example. This new web browser developed by Brendan Eich, co-founder of the Mozailla project and creator of the JavaScript language, in addition to providing a new level of privacy and security protection, Brave enables a blockchain system designed to transform the relationship between users, advertisers and content creators. Its “Basic Attention Tokens” (BATs) are tokens for a blockchain-based advertising platform. The project aims to eliminate third-party advertising transactions, protect user privacy, reduce advertising fraud, and share content with users. Revenue to reward users' attention to improve online advertising. _ Translator's Note) will allow publishers and advertisers to monetize value-added services to gain part of the growth associated with the advertising business, 73% of which is driven by Facebook and Google dominates.

As blockchain becomes mainstream, all intermediaries will need to adapt their business models. The decision-making chain changes structurally:

Individual consumers will have greater control over how they share their private information;

Consumers will decide how to spend time with advertisers Interactive;

Spam and phishing scams are blocked, and from a cost perspective, the more spam they send, the less sustainable their business will be.

From a business perspective, this may mean a higher quality of traffic for all marketing promotionslevel of control capabilities and a better understanding of consumer behavior based on data management.

On the other hand, ads cannot be served without a transactional fee being paid to each affected individual. Consumers will also be motivated to post real and accurate social information online, such as describing content of interest, etc., and they will also pay for it. Instead of paying marketing fees to social media middlemen, marketers will pay directly to the end consumer. When the target consumers are high-value customers, the incentive mechanism will also increase, and the marketing will directly hit the bull's-eye.

Blockchain technology has great potential in reshaping social trust, making social trust more powerful, increasing visibility, connecting multiple resources, and rewarding individuals for their contribution to transactions. Marketing activities and the advertising industry have will be fundamentally affected by these changes. Not only for the company's top marketing leaders (CMO, chief marketing officer), but also for decision-makers such as corporate strategic planning, finance, and technology decisions, pushing them to design and implement blockchain as a priority business matter. From an operational perspective, companies may establish new high-level trust models with consumers and ultimately connect consumers with products through credible marketing campaigns.

Marketing managers and technology managers are likely to use blockchain technology to reshape corporate customer relationships. Early introduction of this far-reaching technology will help companies seize market opportunities and benefit from this technology. Benefit in advance from technologies that will be widely used in the future.

5. How does blockchain help new retail sales links?

The ecosystem of the smart blockchain rental chain is sufficiently active , and even allow people who share the same consensus but are far apart to form and maintain a community. Consensus means common pursuit and common preferences.�
After grasping this point of consumers, it will be more conducive for merchants to create consumption scenarios, cultivate consumers' minds, and facilitate transactions in a timely manner.

6. What are the applications of blockchain technology in business

1. Banking industry
A bank is a secure storage warehouse and value exchange center, and blockchain As a new type of digital transaction method, chain can prevent financial risks more safely and is even more outstanding in the current financial field. UBS and the British Barclays Bank have successively carried out blockchain research experiments. It is hoped that the cost of settlement middlemen can be reduced through the decentralized ledger characteristics of blockchain technology.
2. Payment and cash transactions
Today’s transaction model has been fixed for hundreds of years. Nowadays, the intervention of blockchain technology is to create a more simplified transaction system, which can create a better future for the existing cash transaction model with the characteristics of decentralization, convenience, borderlessness, ultra-low rates, and instant transaction arrival. "Business Structure".
3. Traceability of academic certificates and training
Using blockchain technology to certify academic certificates will ensure that students’ education and training are traceable. If the future education system can adopt open and transparent academic certificates and results Certificates and diplomas can better solve the problem of academic qualification or certificate fraud, and solve the labor cost and certificate manufacturing cost.
4. Copyright certification
“Traditional copyright protection methods include copyright registration, judicial appraisal and notarization. These are all effective methods to protect originality, but they are time-consuming and labor-intensive. Traditional media consumes a lot of money in After spending time and energy to produce content, the traditional methods of copyright protection seem a bit helpless. It takes as much time and energy as creating content. For example, a single creative article worth a few hundred yuan, or even dozens of yuan, is Hundreds of dollars must be spent on copyright protection, which is unacceptable to many creators.
By developing blockchain-based digital rights management (DRM: Digital Rights Management) technology, the works Each authorization or copyright owner records and tracks the copyright of the work at the time of release, giving managers and authors stronger control over intellectual property rights. Blockchain technology can help authors, artists, Photographers and other artistic workers register the copyright of their works on the blockchain to prevent infringement.
Blockchain technology provides a simple public database registration to facilitate creators to register on the blockchainrights and obtain the corresponding copyright certificate. If someone copies a work without permission, the blockchain will automatically issue a copyright certificate as a warning. It also records all authorized and unauthorized copying and distribution behaviors, which can be used as management and statistics for the management department and copyright owners, and can also be used as evidence in court for infringement.

5. Public welfare and charity
The characteristics of the blockchain itself are to solve the "trust" problem in charity fundraising. The blockchain is a digital account book that cannot be tampered with. It is based on the block chain. In the transaction model of blockchain technology, there is no central organization or central server. All transactions are recorded in the blockchain distributed database, which means that the donations or benefits raised can be effectively distributed to all parties. The entire process needs to be simpler, safer, more transparent and more authentic in human hands.
Triporg: It is a travel service platform that uses blockchain technology to provide booking services such as air tickets and train tickets.

7. What are the applications of the hot blockchain technology in the financial system

The ecological token IA can be exchanged for Bitcoin Diamond BCD at a certain ratio.

8. What role can the now popular blockchain technology play in the automotive industry?

Blockchain technology plays an important role in the development of the automotive industry, such as: The formation of ecological alliances in the industry supply chain, applications in the second-hand car market, applications in automotive safety, etc.

1. Automotive industry supply chain financial alliance ecology based on blockchain technology

The integrated supply chain information platform based on blockchain technology connects enterprises in the automotive supply network with alliance chains Through the SDPOs consensus mechanism, a chain information system is established to establish a multi-center efficient supply system. Auto parts sources, production processes, sales channel tracking, maintenance records and other important information are all recorded in this chain. The information generated in the automobile manufacturing process will automatically trigger the corresponding smart contract, realize the automatic recording of the transaction information of upstream and downstream enterprises in the power supply chain, and automatically transfer the payment, and ultimately form a system with the automobile product information flow as the main body, the business flow and the logistics flow as the flow and The information structure supported by capital flow enables efficient and accurate storage and traceability of product information.

9. What applications can blockchain technology have in the supply chain?

Blockchain technology in the supply chainThe application in the blockchain first provides credit guarantee. The blockchain records the circulation information of commodities, etc., which can prove the true reliability of commodities and their circulation, so as to make a comprehensive evaluation of the utility of enterprises on the chain. It has become an effective guarantee for corporate bank loan credit, financing credit and transaction credit.

First of all, the blockchain can time-stamp all transaction data in the supply chain and cannot be tampered with at will. Even if the transaction data of a certain node can be tampered with, it cannot be tampered with. Only one hand covers the sky, so blockchain solves the bank's concerns about corporate information being tampered with. For some small businesses, as long as they have good credit, the possibility of borrowing from banks will be greatly increased.

Secondly, through effective integration, the information between upstream and downstream enterprises recorded in the blockchain can not only provide support for enterprises in production, sales and other links, but also provide downstream enterprises with the ability to analyze customer preferences. , so that targeted services can be developed.

10. How to apply blockchain technology in the field of e-commerce

There is already such an application in the world, called g‏ojo‏y. The prospect is very optimistic. Through consumption, you can mine. The model stimulates consumers to shop in this mall. Consumption is investment. Anyway, you can buy wherever you buy. There are also digital assets that can be mined here. The digital assets mined have room for appreciation and can be held or exchanged for money. I only learned about this after listening to the Blockchain Business Revolution on Qianchao. There is a lot of related content in it!
