It is reported that the country allows non-Estonian residents to apply to become e-citizens, similar to a permanent residence permit or identity card, which enables these residents to enjoy a range of services provided by the country. Currently, Estonia uses this program to encourage talented people from all over the world to start businesses in the country. Such plans would provide a significant boost to tourism in some destinations. You can pay more attention to bitmom

⑵ What are the application cases of blockchain

Currently, companies in medical, government, transportation, technology, manufacturing, entertainment, games and other fields are already using the area. Blockchain technology. As shown in the figure below, blockchain has proven to be very useful in various fields. Currently, listed companies using blockchain include Facebook, Alibaba Group, Microsoft, Siemens, Ford Motor Company, etc.

⑶ What are the applications and successful examples of blockchain?

Blockchain can be applied to all walks of life, taking e-commerce as an example. To solve the pain points of e-commerce in aspects such as counterfeit goods, logistics, integrity, and supervision, major companies and platforms are also showing off their skills and tricks. Blockchain is used as one of the more feasible means, so how does it solve these problems?

First, supervise the production process of goods. When visiting online stores, the biggest worry is buying fake products, especially overseas products. In addition, there is also the price problem caused by fake products. How to buy products at reasonable prices while ensuring the authenticity is really a headache. The transparency and irreversibility of blockchain technology allow consumers to check the production place, manufacturer, raw materials, etc. of goods at any time.

Second, trace and track the transportation of goods. A series of operational activities such as supply chain, inventory, and logistics involved in e-commerce will involve multiple intermediaries. The decentralized, non-tamperable, and traceable characteristics of blockchain make the entire process transparent, and any partner can You can check the inventory and payment status, which can effectively solve the "bullwhip effect" problem in the supply chain. (Bullwhip effect: refers to a phenomenon of demand variation amplification in the supply chain. The fundamental reason for its occurrence is the lack of communication and trust mechanisms between upstream and downstream enterprises in the supply chain. Demand information is transmitted upwards along the supply chain. Keep misinterpreting.) At the same time, blockchain’s smart contracts can be used to regulate intermediaries, such as logistics and payment management partners. Simplify the huge management system to improve efficiency.

Third, guarantee product sales and after-sales service. At present, three-quarters of the transactions in China's e-commerce market are completed on the mobile terminal. Payment trust is a major problem that the platform needs to solve, and blockchain is known as a "trust machine." To give you an example, many websites Stores will fake orders or falsify data in order to get good reviews. Once the purchase information is uploaded to the chain, it cannot be tampered with and authenticity is guaranteed. You can check the real transactions of the merchants.Records to ensure whether the merchant is trustworthy.

Fourth, protect user privacy. The private key, public key, and encryption algorithm of the blockchain can solve this problem. Each user has his own independent address, and due to the anonymity of the blockchain, companies cannot publish or store user information and are protected from hackers. s attack.

For specific implementation, we take the two domestic e-commerce giants as examples. Alibaba has begun to introduce blockchain since 2016. First, Ant Financial launched blockchain technology to pay for charity donations, which was the first test of blockchain technology; in 2017, Ant Financial’s technology experiment The Office announced the opening of blockchain technology to support imported food safety and product authenticity traceability; in 2018, Cainiao and Tmall International announced the use of blockchain technology to track and verify the full logistics information of cross-border imported goods. These data include goods The country of origin, country of shipment, loading port, mode of transportation, import port, bonded warehouse inspection and quarantine order number, customs declaration number, etc.

Logistics and product traceability are indeed a good entry point for blockchain to enter the e-commerce field. As one of the domestic e-commerce giants, JD.com is certainly not to be outdone. In 2017, JD.com announced the establishment of " Jingdong Quality Traceability Anti-Counterfeiting Alliance", united government departments at all levels to build a Jingdong blockchain anti-counterfeiting traceability platform through the alliance chain; in December of the same year, it jointly announced the establishment of the China National Engineering Laboratory for E-commerce Transaction Technology with Walmart, IBM, and Tsinghua University The first safe food blockchain traceability alliance.

⑷ What are the application examples of blockchain technology

The express logistics industry is an industry that is very suitable for the application of blockchain technology.

In fact, the logistics ecosystem is relatively complex and there are many groups involved in the process.

The industry itself is a complex of segments with the concept of "flow". Starting from the initial "business flow", it gradually gave birth to "logistics", as well as the corresponding support of "capital flow" and "information flow" , complete the service chain.

There is a key issue behind the emergence of various "flows", which is the transfer of commodity ownership.

Coincidentally, many of the types of problems solved by blockchain technology are related to the trust friction generated during the transfer of asset ownership.

The application of blockchain technology can significantly improve the processing speed and efficiency of settlement business in the express logistics industry, effectively solve the problem of traceability and anti-counterfeiting of items, and fully ensure information security and the privacy of senders and recipients.

In the field of promoting application in the express logistics industry, there are domestic blockchain companies doing applications in this area, such as Walton Chain.

Last year, Waltonchain reached a strategic cooperation with Huodou (Xiamen) Technology Co., Ltd., using Waltonchain’s “RFID blockchain” technology solution to help it improve its logistics solutions and move goods to Dou uploads data to the chain in all aspects of its logistics turnover, such as reading and writing at key nodes such as entering and exiting warehouses and receiving goods.After the system, when the object passes through any link, the relevant data can be read by the RFID reader, and the corresponding behavior is converted into data and uploaded to the blockchain. Users can trace the entire logistics process with one click.

Four business scenarios that can be implemented in the real environment are suitable for the application of blockchain technology.

Scenario 1: Insured express delivery

Revolving around the insured scenario, express companies transport goods, insurance companies provide guaranteed goods, merchants provide goods sales, sellers purchase insured services, and the government regulates the industry.

So, what should be recorded on the blockchain? There are several key points. The logistics details of the goods, accounts, identities, claims, other reference data and other information are recorded on the blockchain.

Insured price is the concept of a contract. When the customer signs for the package normally, the account claim is automatically triggered, the contract ends normally, and the premium is automatically cleared. If there is a problem or missing piece, the insurance company's claim process will be triggered.

Scenario 2: Charity express delivery

For charity activities, such as the "One Cent" campaign, one cent from the cost of each charity package is donated to the account of the charity organization . In this scenario, the express delivery company is still responsible for the transportation of goods, the public welfare organization provides the execution of public welfare activities, and the poverty alleviation merchants provide the sales of public welfare and poverty alleviation products.

Then what is recorded in the blockchain is the logistics details of the goods. After the package is signed for, it will be recorded on the blockchain, automatically triggering the transfer from the logistics company's public welfare account to the public welfare organization's account. When the public welfare activities are completed, the entire process is open and transparent, which avoids the public's distrust of social welfare activities.

Scenario 3: Industry blacklist sharing

At present, the blacklist of express delivery employees is still mainly offline. We hope that through blockchain technology, each company can record the blacklist of employees on the blockchain, and other companies can also query it, and the data cannot be modified, and can be traced back to which company this person worked in What kind of inappropriate behavior and other information.

Scenario 4: Supervision of safety incidents in postal delivery channels

Many express companies will install security inspection machines, and the government also wants to know whether each logistics company has any transportation safety hazards. Through the distributed accounting model, each express delivery company can record the effective information of the security incident on the blockchain when a security incident occurs, so that regulatory agencies can monitor it in real time and cannot be tampered with.

⑸ What are the application examples of blockchain technology

Application of blockchain technology in voting
Kuaishang is the first country to apply blockchain technology to In the field of voting, it effectively solves the problem of trust in voting data, provides the most authentic and effective data to activists, and protects the rights and interests of real voting users. At the same time, it makes blockchain technology "people-friendly" and allows the general public to quickly perceive and enjoy the area in the field of life services. The convenience brought by blockchain technology.
Application of blockchain technology in digital asset registration
GoldThe main digital asset service platform is the first to use blockchain technology, which is a globally accepted distributed ledger technology that is traceable, non-tamperable and non-forgery. The digital assets of the platform come from regulated digital asset issuers, and the value of the assets is determined through the open market to avoid overestimation or underestimation of value.
The application of blockchain technology in the financial industry
Ant Financial’s independently controllable financial-grade commercial blockchain platform has been deployed globally in multiple institutions and countries in multiple social and commercial application scenarios. Ant Blockchain Chain platform transactions support second-level confirmation, and the consensus mechanism uses an efficient parallel consensus algorithm to ensure the high performance of the blockchain platform. Ant Blockchain has already had multiple production-level applications, applying leading technology to people's livelihood and business. , finance and other fields.

⑹ What are the examples of blockchain application development

Government Management
Some countries have expressed interest in blockchain technology using a decentralized data management framework to store public data. There is great interest, for example, Essentia is piloting an e-government project with the Central Union of Agricultural Procers and Forest Owners of Finland, which will apply blockchain technology to urban and rural residents across Finland. It can query various records to fully meet the needs of residents and employers and improve the employment rate. In addition, the use of this technology can also improve the efficiency of government operations, allowing residents to easily query various information such as education, public records, and voting.
Waste Recycling
For example, a smart waste management system in China uses Waltonchain’s RFID technology. Using Waltonchain’s blockchain application, waste levels can be effectively monitored to improve management and operation efficiency and Resource optimization.
Identity Recognition
The Swiss city of Zug, known as the “Crypto Valley”, has developed an identity authentication system using blockchain technology with its partner company Uport. Through this identity authentication system, citizens can easily Good to participate in online voting and proof of residence.
Border Control
EssenTIa has been in contact with the Dutch government, hoping to use its blockchain technology to build a border inspection system for the Dutch government to screen passengers traveling between Amsterdam and London. Currently, Eurostar high-speed rail passengers between the two countries need to undergo border control checks at multiple locations. EssenTIa is working on a blockchain-based solution that will securely store passenger data so that Dutch inspection records can also be reviewed by UK border agencies. Blockchain technology will ensure that data has not been tampered with and is verifiably accurate.
Healthcare
It is well known that medical records are fragmented and error-prone. Inconsistent data processing processes often leave hospitals and clinics forced to process incorrect or incomplete data.patient records. MedRec, a blockchain electronic medical record system developed by the Massachusetts Institute of Technology in the United States, uses blockchain technology to promote data sharing. At the same time, it can also provide authentication and confidentiality services.
Enterprise Management
As enterprise customers of Microsoft Azure Apps, they can take advantage of Blockchain as a Service (BaaS), which will enable enterprises to access smart contracts and blockchain applications in a secure hosting environment. According to media reports, Google is also developing a proprietary blockchain project to support its cloud-based business. Google's parent company Alphabet is developing a distributed accounting project that third parties will be able to use to store data related to Google Cloud services.
Medical Data
Medical centers that digitize patient records do not store data across multiple devices. Instead, they typically store data on centralized servers, which is a major target for hackers. Target, as evidenced by the Wannacry attack on NHS hospitals in the UK. But beyond that, even if security risks are ignored, there is still a problem of fragmentation. Currently, there are more than 50 different electronic medical record systems (eHR) in operation in hospitals in different cities around the world, and there are usually dozens of different medical application systems in the same city. These independent systems cannot perform interoperable retrieval, and patient data in various hospitals can only be scattered in different data storage centers.
In patient life-and-death situations, the lack of comparison of reliable medical data and slow operating efficiency will be fatal. EssenTIa's application framework solves all these problems by using a blockchain-based system that will All clinically relevant patient data is stored and instantly accessible regardless of geographic boundaries. In this system, the privacy of patient medical records can also be protected, and only those with medical authorization can access it during specific time periods.
Music Production
One of the main benefits of blockchain technology is that it eliminates unnecessary middlemen or middlemen, the music industry is a prime example of this where if the artist is inefficient then the This will directly result in low remuneration for them. At this time, some blockchain-based projects emerged, dedicated to seeking a fairer transaction and business environment for music creators, such as Artbit, a company where former Guns N’ Roses drummer Matt Soren is the director.
Carbon Offset
As a highly industrialized country, China’s environmental changes have been huge. In March 2017, IBM and Energy-Blockchain Labs jointly launched the Hyperledger Fabric blockchain project to use it to discover China's carbon assets. This not only creates a reliable way to track carbon emissions. A measured and auditable system also provides companies seeking to offset energy consumption while incentivizing green industrial practices.Provides a tradable market.
Supply Chain Management
Supply chain management is considered to be one of the better cases of applying blockchain because it is very suitable for express delivery or delivery of goods from shipment to receipt. The entire process from manufacturer to store. IBM and Walmart jointly launched the Blockchain Food Safety Alliance in China. The project is also run in cooperation with JD.com, aiming to improve food delivery tracking and safety assurance, making it easier to trace food safety issues.
China has proven to be a mature testing ground for blockchain projects, and it is also home to the world’s first blockchain for agricultural products (5.180, -0.25, -4.60%). World-renowned food trader Louis Dreyfus Co has partnered with Dutch and French banks to establish a blockchain technology project that will enable transaction settlement in the process of selling soybeans to China to be faster than traditional settlement. Method is faster.
Diamond Industry
The world’s most famous diamond company, De Beers Group, has its own blockchain company and has begun operations, with the aim of “for every diamond registered on the platform. Diamonds create a digital record”. Taking into account people's concerns about the source of diamonds, the ethical standards of origin, and the risks of diamond quality, blockchain technology is naturally a good choice, because every record of it is indelible, and it will ensure the authenticity of every diamond. The electronic data itself is as long-lived as the data itself.
Real Estate Transactions
Currently, Ukraine is the first country to use blockchain technology to facilitate property transactions. Michael Arrington, the founder of the famous technology website TechCrunch and a cryptocurrency player, used the smart contract of the Ethereum blockchain to remotely purchase and resell a property in Kiev. This transaction was conducted by a professional in the blockchain industry. Completed by Propy, a startup that specializes in on-chain real estate transactions.
Fisheries
Blockchain technology is now being used to support the development of sustainable fisheries. Illegal fishing is a common problem in the industry, and blockchain's distributed ledger technology provides a way to prove where the catch comes from, how it is processed and sold. This “net-to-fork” supply chain allows inspectors to determine whether the fish being caught comes from areas that violate human rights, or from countries affected by economic sanctions.
Art Paintings
Similar to the diamond trade, the art industry relies on the provenance and authenticity of artworks. Although blockchain cannot identify whether a painting is an original or a fake, it can be used to prove that the Identification of previous owners of the painting. In addition, blockchain technology is now also being used as a means of acquiring art, allowing tangible items to be easily traded and exchanged anywhere in the world without the need for physical transfer from secure storage.
Public Facilities
In the Australian city of Fremantle, a project dedicated to distributed energy and water system management isUsing blockchain technology, solar panels are being used in sunny areas to capture electricity, which is then used to heat water and provide electricity. All this energy conversion and usage information will be Recorded in blockchain data.
In Chile, its National Energy Commission has begun to use blockchain technology to verify the country’s energy usage data. Some sensitive data will be stored in the blockchain. The application of this technology can be regarded as the electricity foundation of this South American country. A means of modernizing facilities and operating them safely.
LGBT Rights
Blockchain helps build the “pink economy” and also helps the LGBT community fight for their own rights without revealing people’s identities. This is an extremely This is an important issue because crimes of discrimination against the gay community often arise, especially in countries notorious for human rights violations where homosexuality is illegal, or at least not allowed.
Catastrophe Bonds
Catastrophe Bonds may be the only hope for victims of earthquakes, tsunamis and other natural disasters. Blockchain allows for fast and transparent reconciliation between parties and ensures that the system can continue to operate normally without human intervention. Blockchain is now successfully used in the settlement mechanism of catastrophe bonds.
Tourism
Local institutions in Hawaii are studying how to use blockchain technology to improve the economy, such as opening Bitcoin and other currency payment methods to facilitate tourists' transactions for local goods and services. Using this method, the Hawaiian government hopes to vigorously attract tourists, especially tourists from Asia, to spend more money locally and enhance Hawaii's economic development.
Homeland Security
In 2016, the U.S. Department of Homeland Security (DHS) announced a project that would utilize blockchain technology as a means to securely store and capture data transmissions. DHS uses Factom’s blockchain technology to encrypt and store data captured by security cameras and other sensors. The application of this blockchain technology will greatly reduce the risk of data leakage. Currently, the project is still in progress.
Maritime Transportation
The benefits of blockchain for recording ship transportation data are self-evident. Currently, shipping projects in some places have adopted distributed ledger technology. In the maritime logistics industry, blockchain Chain technology can make the inevitable cumbersome management procedures in international trade more transparent and orderly. Maersk, one of the world’s largest ocean carriers, was a pioneer in utilizing blockchain, and now ZIM, an international shipping company, has followed suit.

⑺ What are the most likely applications of blockchain technology in the energy field?

Chongqing Jinwowo analyzed the application cases of blockchain technology in the energy field as follows:< br />
1. Electric vehicle solutions, such as distributed charging piles and sharedEnjoy the car.

2. Establish a personal energy system and buy and sell electricity, solar energy, gas and other energy sources.

3. Support community energy models, battery management, and build a conservation-friendly power pool.

4. Connect energy buyers with operators of renewable energy systems.

⑻ Briefly explain what blockchain is and give an example!

For example:
The village chief’s conspiracy has been exposed! Who did it? Be bold!

It is said that the village chief of Maoxian Village, Mr. Wang, is a symbol of power in the village and is highly respected.

Every household in the village has transactions with each other. For the sake of fairness and justice, every household in the village must ask Village Chief Wang as a guarantee and record the information in his account book, but they must charge 1% of the transaction amount. , everyone is willing to trust him.

Suddenly one day, it was discovered that Village Chief Wang had accepted bribes from one party and maliciously tampered with the account books, causing serious losses to the other party.

All the villagers angrily decided to abolish his rights. Some villagers suggested that we all have an account book in the future. When a transaction occurs, we will shout at the entrance of the village. More than 51% of the villagers confirmed this transaction information. It will be regarded as passed, and the village’s account books will be open and transparent from now on.

The ledger of each villager is a block. Someone shouts at the entrance of the village, and everyone connects to confirm the ledger information is a chain. The combined system is a blockchain system. (Borrowing an example from the Zambi community)

⑼ What are the cases where blockchain has been applied to the industry

1. WeBank uses blockchain technology for loan settlement
In September 2016, WeBank and Shanghai Huarui Bank launched a trial operation of an inter-bank joint loan clearing platform based on alliance blockchain technology to optimize the settlement and clearing of the "Weilidai" joint loans of the two banks. With the introduction of this blockchain system, all information is recorded on the blockchain network and cannot be tampered with. It is liquidated simultaneously during the transaction process, achieving real-time liquidation and saving a lot of manpower and material resources.
2. China UnionPay uses blockchain technology to realize cross-bank point redemption
In September 2016, China UnionPay and IBM piloted a shared points system using blockchain technology. The use of this blockchain system allows users to redeem reward points across banks and platforms. That is to say, a user's points in one bank can be exchanged for points and rewards from other banks, or even multiple airline miles and supermarket rewards. The efficiency of using bank points has been greatly improved.
3. Toyota Motor uses blockchain technology to track auto parts
In October 2016, Toyota Motor joined the R3 Alliance and uses blockchain technology to store the production, processing and usage of each part in In the blockchain, in this way, if there is a problem with a car part, the source of the part can be easily and quickly queried.
4. Central Bank Blockchain Digital Bill Trading Platform
In January 2017, the blockchain-based digital bill trading platform promoted by the central bank was successfully tested. The introduction of digital currency for settlement can realize the simultaneous transfer of capital flow and information flow in digital bill transactions, thereby realizing DVP pay-versus-payment settlement. At the same time, the blockchain digital identity solution solves the problem of repeated KYC authentication for users between different financial institutions. It not only solves the problem of keeping the information of parties unrelated to the transaction confidential in the amount of digital bill transactions, but also ensures that regulatory parties such as the securities exchange have a see-through mechanism when necessary.
5. Ant Financial Blockchain Application
In August 2017, Ant Financial’s blockchain technology tested the waters of insurance and helped Xinmei Life Insurance Co., Ltd. launch the first charity rescue account in the domestic insurance industry. Blockchain technology makes every fund flow open and transparent, every fund flow data cannot be tampered with, and the whereabouts and use of every fund can be traced. In November of the same year, Ant Blockchain was used for food safety traceability and product authenticity traceability. Currently, users only need to scan the milk powder produced in Australia and New Zealand and China's Moutai to know whether it is genuine.
There are many other domestic and foreign cases. These successful cases all indicate that the application of blockchain technology is gradually being implemented and promoted, and is favored by various industries. Along with this, many blockchain technology companies have sprung up, all wanting to get a share of this field. However, after the People's Bank of China and other seven ministries and commissions issued the "Announcement on Preventing Financing Risks of Token Issuance"), as the difficulty of registration increased, more and more intermediary industry chain-type shell companies have practical applications. Companies are few and far between.
In addition, the security technical issues of blockchain have always attracted much attention and controversy. Blockchain currently faces five major security issues: the security of the underlying code, the security of the cryptographic algorithm, the security of the consensus mechanism, the security of smart contracts and the security of digital wallets.

⑽ Give examples of other practical applications of blockchain

Starting from November 8, the Walmart Jinhai Road branch in Baoan, Shenzhen will provide users with blockchain electronic invoice issuance services. , the electronic invoice issued will be directly entered into the consumer's WeChat card wallet. This is the first time that electronic invoices have been applied to large chain retailers.

In fact, on August 10 this year, Shenzhen’s Guomao Revolving Restaurant issued the country’s first blockchain electronic invoice. So, what are the characteristics of blockchain electronic invoices that make Shenzhen, a pioneer city in the country, willing to use it as an important "Internet + Taxation" project between the Shenzhen Taxation Bureau and Tencent in the "Smart Tax" Innovation Laboratory this year? What about floor-to-ceiling products?

1. It is more convenient to issue invoices

In the past, when issuing invoices in supermarkets, you had to check out at the cashier and then go to the service desk to queue up and issue invoices based on the shopping receipt. If the user provides wrong information at this time, it will be very troublesome to void the invoice and reopen it. The emergence of blockchain electronic invoices allows companies to apply for invoices on the blockchain; useUsers can issue invoices on the chain. After the transaction is completed, they can apply for invoices by themselves by scanning WeChat on their mobile phones. Invoice collection is electronic and convenient, achieving "instant invoicing after transaction", making the entire process more convenient and faster.

2. Supervision is more convenient

Since blockchain electronic invoices are issued directly in the system, there are fewer human intervention factors, and for tax regulators and managers, the tax bureau In other words, technological innovation can achieve full-process supervision, realize paperless intelligent tax management, and make the tax process more controllable.

3. Financial information is more authentic and reliable

Due to the addition of the underlying technology of blockchain, the information on electronic invoices becomes tamper-proof, which makes internal financial statistics within the enterprise. Various opportunities for fraud are avoided, the financial reimbursement process is optimized, and work efficiency is improved.

It is almost foreseeable that with the participation of global giants such as Wal-Mart, electronic invoices will be used in more fields. In the context of this year's tax reform, technological development will also provide greater support to the tax system of Shenzhen, an international metropolis.
