What are the application examples of blockchain?

1. Judicial deposition

On September 18, 2018, the Hangzhou Internet Court officially opened the chain, becoming the world’s first court to use blockchain for trials.

It is understood that the complainant can submit electronic evidence such as the contract, rights protection process, service process details, etc. online through the online complaint portal to nodes on the chain such as notary offices, judicial appraisal centers, CA/RA institutions, and courts. Come and witness and endorse together to provide one-stop service for the prosecutor. The Internet Court of Hangzhou, Zhejiang Province publicly pronounced its judgment on a dispute over infringement of the right to disseminate work information online, and for the first time confirmed the legal validity of electronic data stored using blockchain technology.

2. Logistics field

In early 2018, Cainiao and Tmall International jointly announced that they have used blockchain technology to track, upload, and verify the logistics of cross-border imported goods. Link information.

After all nodes in the logistics chain are connected to the blockchain, the goods will be traceable from the manufacturer to the consumer, forming a complete chain; the more links the goods are missing, the more fake they will be exposed. Product probability is greater.

3. Electronic invoices

On August 10, 2018, Shenzhen Guomao Revolving Restaurant issued the country’s first blockchain electronic invoice. It is understood that this issued block The chain electronic invoice is led by the Shenzhen Municipal Taxation Bureau and Tencent provides underlying technology and capabilities.

Different from traditional electronic invoices and simple electronic invoices uploaded to the chain, this blockchain electronic invoice combines "fund flow and invoice flow" into one, integrating invoice issuance and The combination of online payment simplifies the entire process of invoice application, invoicing, reimbursement, and tax filing.

There are many practical applications of blockchain, you can learn more about the relevant information.

㈡ What are the applications and successful examples of blockchain?

Blockchain can be applied to all walks of life. Taking e-commerce as an example, in order to solve the problem of counterfeit goods, Regarding pain points in logistics, integrity, supervision, etc., 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 Can viewInventory and payment status 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 to ensure authenticity. You can check the merchant's real transaction 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.

iii The understanding of “blockchain” and the application of “blockchain”

The understanding of “blockchain” and the application of “blockchain”
“ "Blockchain" can be said to be the hottest keyword right now. Whether it is online information or daily chat, you can hear about it everywhere. Although there is a lot of discussion, most people are still relatively ignorant about "blockchain". Therefore, we often hear many peopleAsk "What is blockchain technology?" "What is the relationship between digital currency and blockchain?" "How can you identify a good blockchain project?" and other related questions.

As for what exactly is blockchain?
Blockchain technology refers to a way for all people to participate in accounting. There is a database behind all systems. You can think of the database as a big ledger. Currently, each system keeps its own account.
But now in the blockchain system, everyone can keep accounts. The system will automatically select the person with the best and fastest accounting, write the contents of his accounting into the ledger, and record the information in the ledger. The content is distributed to everyone in the system for backup.
So what are the benefits of such universal accounting?
First of all, the biggest benefit is security. With this central ledger, others cannot change or destroy it, because it is not a computer Computer control can not only greatly reduce costs, but also improve efficiency. And since everyone has the same ledger, it can ensure that the ledger recording process is open and transparent.
Secondly, the most important thing about blockchain technology is that it can solve the problem of intermediary credit. In the past, it was difficult for two people who did not trust each other to cooperate and had to rely on a third party, just like transfers must go through a bank, but through Blockchain technology, Bitcoin, without the participation of any intermediary agency, has for the first time achieved a transfer behavior in which both parties can trust each other;
Because the blockchain does not require the participation of an intermediary, the process is efficient and transparent, and the cost is very low, Data is highly secure, so any industry or field that has needs in any of these three aspects will have the opportunity to use blockchain technology.

If you still say that "blockchain" can only be used for currency speculation, then you are too behind:
With the improvement of living standards and the upgrade of the consumption era, many people like to buy when traveling abroad Buy, buy, even people who don’t go abroad also like to buy some imported goods online. As a result, cross-border online shopping has risen rapidly in recent years. However, many processes and links of cross-border online shopping occur abroad. As a cross-border online shopping user, how can you ensure that the goods you buy are not A-grade or counterfeit goods?
In order to solve the problem of allowing consumers to buy their favorite goods At the same time, it is genuine and licensed. Now we have a reliable and convenient solution, which is blockchain technology. It has the following characteristics:
1. Use block chain data structure to verify and store data.
2. Use distributed node consensus algorithm to generate and update data
3. Use cryptography to ensure the security of data transmission and access
4. Use smart contracts composed of automated script codes to program and manipulate data
Nowadays, many e-commerce companies have taken a fancy to these advantages of blockchain technology and use it for overseas purchase business, such as JD.com. It is understood that JD.com has now reached cooperation with brands such as Kelaisi Mask, Zhengguanjang Korean Ginseng and Red Ginseng, Amore Cosmetics, Oberton Apricot Dried Raisin Fruit Oatmeal and other brands. With the help of regionalBlockchain technology integrates and writes information on the raw material process, production process, circulation process, and marketing process of these brands' commodities into the blockchain to achieve full-process authenticity traceability down to one item and one code.
Thus, each piece of information has its own unique blockchain ID "identity card", and each piece of information is accompanied by the digital signature and timestamp of each subject for consumers to query and verify. The data signature and encryption technology of blockchain enables full-link information to achieve tamper-proof, unified standards and efficient exchange.
Now that we have reliable technology like blockchain, and reliable cross-border traceability and cross-border logistics, we no longer need to go abroad to buy in person, nor do we need to worry about what we are doing on e-commerce platforms. The product purchased is not genuine. As long as we sit at home and move the mouse, our favorite overseas big-name products will arrive as scheduled. I believe that in the near future, blockchain technology will also be applied to other e-commerce companies.

㈣ Can blockchain be used in cross-border payments

Yes
Blockchain technology refers to a way for all people to participate in accounting. There is a database behind all systems. You can think of the database as a big ledger. Currently, each is keeping its own accounts.

㈤ What are the main application areas of blockchain technology?

Answer: The main application areas of blockchain technology include the financial field, the Internet of Things and logistics, public services, and digital copyright. , insurance field and public welfare field.

1. Financial field

Blockchain has potential huge application value in financial fields such as international exchange, letters of credit, equity registration and stock exchanges.

2. Internet of Things and Logistics Fields

Blockchain can also be naturally combined in the Internet of Things and logistics fields. Through blockchain, logistics costs can be reduced, the production and delivery process of items can be traced, and the efficiency of supply chain management can be improved.

3. Public service fields

Blockchain is closely related to people’s production and life in public management, energy, transportation and other fields, but the centralized nature of these fields also brings Some problems can be solved using blockchain.

4. Digital copyright field

Through blockchain technology, works can be authenticated, prove the existence of text, video, audio and other works, and ensure the authenticity and uniqueness of ownership. sex.

5. Insurance field

In terms of insurance claims, insurance institutions are responsible for fund collection, investment, and claims settlement, and often have high management and operating costs.

6. Public welfare fields

The data stored on the blockchain is highly reliable and cannot be tampered with, so it is naturally suitable for use in social welfare scenarios. Relevant information in the public welfare process, such as donation projects, fundraising details, fund flows, recipient feedback, etc., can be stored on the blockchain and transparently and publicly disclosed conditionally to facilitate social supervision.

㈥ How to apply blockchain in cross-border payment

The actual application model of blockchain cross-border paymentIt uses the blockchain network to add traditional financial institutions, foreign exchange market makers, liquidity providers, etc. to the payment network to build a payment gateway. Through the payment gateway, the flow of digital assets on the blockchain can be connected with the legal currency in reality, so that the legal currency can be converted into digital assets on the blockchain to facilitate subsequent payment transfers. Through the network connector in the blockchain payment network, traditional market makers, remittance banks, remittance banks and other institutions can be connected, eliminating intermediate transaction links and realizing point-to-point fast and low-cost payments.

㈦ How to apply blockchain technology in the e-commerce field

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

Application Cases of Blockchain + Internet of Things Fusion Technology in the Maritime Field

About Maritime Introduction to Rich Shipping Chain

1. Background

As a traditional and irreplaceable important industry, the shipping industry plays an important role in international The important role of the trade industry chain has always been an important force supporting the development of globalization. The international shipping market is a fully competitive and open market, which has certain risks but also huge business opportunities.

In the traditional investment field of the shipping industry, there are untimely information disclosures and opaque operating data of ship management companies, which has brought a lot of scrutiny to investors and financial institutions. It also brings a lot of inconvenience to the financing of small and medium-sized shipping companies. How to establish a reliable trust system between investors and financiers, establish an effective communication bridge, and effectively serve the capital in the shipping market, has always been This is a problem that the Haifu Fund team is working hard to break through. Now, the Haifu team has created the first digital asset shipping platform, and through the integration of blockchain + Internet of Things technology, it has completely solved the problem of unreal information disclosure and operating data, and also discovered potential opportunities in the shipping market, unleashing the potential of the shipping market, and leading more people to share the dividends of the shipping industry.

The Haifu team is a team of 20The shipping investment team has more than 10 years of experience in international shipping. Its core team members have served as senior managers in large shipping companies such as China Ocean Shipping Group (COSCO), Hong Kong Kaitong, Hong Kong Weili Shipping, and Singapore Wanbang Shipping. The team members are very Familiar with the shipping market and financial market, he is not only good at ship operation, but also good at ship trading and ship investment management. During his many years of shipping career, the founder has owned nearly 20 large dry bulk ships with a total deadweight of more than 100 million tons, the annual turnover exceeds 100 million US dollars, and the average annual investment income reaches 30%.

Haifu Fund and Xinyang Shipping Ship Management Co., Ltd. have established a long-term partnership. Xinyang Shipping Co., Ltd. has an excellent ship management team. The company's team has overcome many technical problems of bulk cargo ships: In terms of navigation technology, we have dealt with many ship maneuvering issues under severe weather conditions; in terms of business, we have also dealt with dozens of charter transport contract disputes, as well as ocean bill of lading issues, ship insurance and other complex issues. .

In order to truly present the operating data, the Haifu team uploaded the core operating data of the partners to the public chain On the market, through the combination of software, hardware and blockchain data, operational indicators are publicized, allowing investors to understand the true situation of ship operations in real time.

Main on-chain data:

1. Through AIS data on-chain, master the real-time position information and navigation trajectory of each ship;

2. Through chartering The shipping contract is uploaded to the blockchain to allow investors to understand the operating income;

3. The voyage benefit calculation data is uploaded to the blockchain to allow investors to understand the operating profit.

In addition, shipping data sensors are installed on the bridge and engine room control room of the ship. The sensor integrates multiple technologies of blockchain + Internet of Things technology. The sensor has both The functions of data collection and real-time data uploading embed blockchain technology into the hardware level, allowing the objective operating data collected by the hardware to be uploaded to the chain in real time, thus avoiding the possible moral hazard of human tampering with data.

1. Compare the ship’s fuel consumption data collected through sensors with the theoretically calculated data;

2. Compare the ship’s mileage data collected through sensors with the actual data at the loading and unloading port;

3. The load calculated by collecting ship draft data through sensorsCompare the cargo volume with the quantity agreed in the transportation contract.

Through multiple cross-references, real-time operating conditions are reflected to investors and financial institutions. In addition, Haifu Company also timely updates and discloses the latest project progress and investment income on the homepage of the website. After expiration, smart contracts are used to automatically execute the deduction of dividends and interest, ensuring that the investment returns of investors and financial institutions are received in a timely manner.

In addition to information disclosure and the authenticity of management data, if the ultimate risk occurs, the Haifu team also has countermeasures: ship asset disposal. The risk of disposal of ship assets is relatively controllable. The international price of scrap steel is basically based on the international price of scrap steel. The international price of scrap steel is relatively stable. It has basically remained at around US$400 per ton for many years. With a load capacity of about 50,000 tons of Panamax ships, the weight of scrap steel is 1 For example, about 10,000 tons, which means that the price of ship scrapping is about 4 million US dollars. Generally speaking, for ships that are about 20 years old, regardless of the rise or fall of scrap steel, scrap steel can basically cover 80% of the ship price. Of course, premiums and losses caused by sharp rises or falls in scrap steel cannot be ruled out.

In addition, the operating income of shipping is also relatively considerable: according to the current market level, the market rental level of a bulk carrier of about 50,000 deadweight tons is about 10,000 US dollars a day, deducting the fixed cost, it is about 4,000 US dollars a day, and The gross profit per day is about US$6,000, and the annual income is about US$2-2.5 million, which also means that an investment of US$5 million, after deducting depreciation, can still recover the investment in three years.

By integrating blockchain technology and Internet of Things technology, the Haifu team will apply it to the shipping industry to bring powerful Promote the rapid and standardized development of the industry, eliminate the complicated due diligence procedures of financial institutions, greatly reduce the investigation threshold for investors or financial institutions, establish technical barriers to credit, and bring stable and reliable investment returns to investors.
