④ What is the relationship between shipping and blockchain?

The combination of blockchain and shipping industry is mainly reflected in the accumulation of enterprise transaction operation data through shipping blockchain to form a large Database, and then create a full-process automatic blockchain system, completely opening up all aspects of the platform and forming an information sharing channel. I heard that ChainNova is doing this, but I don’t know if there is any cooperation.

⑤ The future of the combination of shipping industry and blockchain

We are currently cooperating with a Yunliu blockchain company to solve the paperless problem of ports. In my opinion, blockchain Three points are certain about the application of chain in the shipping industry:
1. Changes in the operation model of the shipping supply chain. The traditional operating model will change, and some institutional functions may also transform. For example, freight forwarding-related institutions may transform into institutions that specialize in providing knowledge services and technical services. On the one hand, the decentralized operating model of the blockchain can not only bypass some intermediaries, but also simplify the operating process, improve operating efficiency, and save operating costs. On the other hand, payment activities based on the blockchain are programmable, that is, smart contracts. Using smart contracts, a large number of documents can be eliminated, and shipping can achieve paperless operations, thereby achieving cost savings. At the same time, through smart contracts, the flow of funds between nodes has become safe and efficient, and payments may be completed bypassing third-party institutions (such as banks).
2. Change the electronic data exchange system of ports and shipping. First, the blockchain will realize the exchange and application of electronic documents such as international trade bills of lading among all relevant entities in trade and transportation; second, the blockchain will realize the integration of the three streams of "logistics, information flow, and capital flow" in the international supply chain. And replace part of the logistics to form a stacking model of online trading channels. When problems arise during the transportation of goods, cargo owners, customs, carriers, and insurance companies can all trace reliable electronic evidence to clearly define the responsibilities of all parties and improve the efficiency of payment, delivery, and claims processing. In the future, various legal documents involved in international trade can also use blockchain solutions similar to bill of lading information exchange to achieve safe, reliable, and mutually recognized transmission
3. Change the credit evaluation system and innovate financial services. The use of blockchain for complex transaction scenarios involving multiple transaction entities should be meaningful. The most important thing in risk control is whether the transaction is authentic, because at the end of the dayThe data at all levels are connected, so it can solve the pain points of the supply chain finance industry. In the platform era, if the credit-related information of relevant transaction entities is stored on the blockchain and can be easily obtained, then transaction entities can directly conduct point-to-point trusted transactions, and the role of the intermediary is closer to that of a technical consultant. In fact, the current application of blockchain technology is indeed gradually transitioning from digital currency to "blockchain+", and gradually extending from the financial field to non-financial fields such as the Internet of Things. In addition, after asset-based shipping resources are put on the cloud in digital form through blockchain, transactions and financing will be more flexible, and asset tracking and management will be more convenient.

⑥ What are the specific application scenarios of blockchain?

Taking the tourism industry as an example, blockchain applications are mainly concentrated in travel, travel community reviews, digital Identity management, credit consumption management, tracking of professional certificates and qualifications of pilots, hotel and airline loyalty programs, reservation management, and consumption points management are several application areas

In addition, blockchain development, many related top domain names have been registered, which has had a relatively large impact on the domain name industry

In addition, blockchain is also used in finance, games, entertainment and other fields

⑦ 12 years of blockchain: In what fields has it been applied?

#「 Shining Moment 」Theme Essay Collection Issue 2#

People have talked about the applicable scenarios and application scenarios of blockchain countless times. Timing of use. But in fact, it is very stupid and ridiculous to simply and crudely bundle blockchain with all businesses.

If you just use the word "blockchain" (rather than the technology behind it) to hype it, the result will be in vain. But if used properly, blockchain can indeed promote the development of certain economic sectors.

To achieve this goal, you need to take it slowly, step by step. Gartner experts believe that blockchain is currently on the verge of “escape from fantasy” stage. At this stage, its technical shortcomings were fully exposed, and most media from all walks of life were critical.

So, are there any good products that are truly based on blockchain? If so, in what areas?

First of all, financial services are a good choice. After all, many traditional intermediaries suffer from low transparency and high commissions. Currently, many large banks are already researching and testing decentralized solutions. So what are the options available on the market now?

Netting is a good example. It is based on Hyperledger Fabric and is capable of offsetting multiple positions or payments resulting from transactions between two or more parties. Often used to determine which party should receive remuneration in a multi-party agreement. As a general concept, netting has many more variations in financial markets (securities trading).for specific purposes.

In addition, there is endless discussion about blockchain bonds, mortgages and bank guarantees. Almost all big banks, including Islamic banks, are trying this approach.

Hyperledger Fabric and Corda blockchain technologies are also often used in other use cases, but the prospects require us to draw final conclusions through continued follow-up and observation.

Bank of America, Goldman Sachs, Citibank, Morgan Stanley, JPMorgan Chase, Bank of China and Commonwealth Bank of Australia have all achieved good results in 2019. In addition, in the banking industry, people often talk about cross-border financial transactions, and there is even an intention to get rid of SWIFT.

Some people believe that blockchain technology has great prospects in copyright protection and combating data fraud. For example, for the purpose of copyright protection, the startup Sputnik DLT developed the Depositor service on the Waves platform.

Likewise, Emernotar is a similar solution based on Emercoin, using the SHA-512 algorithm. According to the developers, businesses and lawyers can use the Emernotar service to sign contracts, use the online service to collect user consents, and creative industry representatives to confirm copyright.

The democracynotary.org platform, powered by Emercoin technology, aims to protect important election-related information. Although the blockchain cannot yet guarantee the anonymity of voting during the election process, it can at least guarantee the authenticity of voting.

The effectiveness of this platform was recently put to the test in a Macedonian referendum on ratifying a treaty with Greece that called for changing the country’s name to “North Macedonia.” ". The platform notarized public reports from the referendum process, thereby blocking the spread of false information.

Blockchain use cases are extremely promising in the registration of real estate transactions. Last year, there were attempts to leverage smart contracts on the Ethereum blockchain to conduct such buy/sell transactions in jurisdictions. While not all local legislatures understand what lawyers are doing, there have been and will be attempts.

For example, the most famous example was a deal to sell 10 acres of land through a decentralized Propy marketplace in California, conducted entirely in Bitcoin and using blockchain To register. Since then, the EU has also completed its first blockchain real estate sale.

In December 2018, the Swiss Financial Market Supervisory Authority approved the commercial transaction of the blockchain company "Blockimmo Real Estate Company"business model. Currently, the Blockimmo platform is in a testing phase and is available to residents of Switzerland and Liechtenstein. After that, the company plans to enter other markets throughout Europe.

Some experts are very optimistic about the application prospects of blockchain in the wholesale and logistics fields; but at the same time, some experts believe that it has no use in this field. However, as consumers, we should recognize the success that has been achieved in the industry.

In the late autumn of 2018, oil giants BP and Shell, as well as large banks and companies, launched the Vakt blockchain platform, which aims to optimize the commodity transaction process - including converting paper documents into smart contracts .

At the same time, the UAE is also using blockchain technology in the field-Maqta Gateway LLC launched the first blockchain logistics solution in Abu Dhabi. The Silsal blockchain technology developed by the company can improve logistics and freight efficiency. Maqta Gateway hopes to use DLT technology to reduce paperwork, facilitate real-time status updates and speed up information sharing.

Last fall also launched the IBM Food Trust Blockchain Platform - based on Hyperledger Fabric technology and designed to regulate the food industry supply chain. Well-known companies such as Carrefour, Nestle, Dole Food, Tyson Foods, Kroger, Unilever, and Walmart are among the Platform members. Monthly fees for IBM blockchain services range from $100 to $10,000, which explains why these industry giants are willing to invest in this area.

The decentralized Shelf.Network auction protocol was launched in the fall of 2017. Car dealers can conduct car sales and leasing transactions through the platform.

A year later, the auction network received investment from Japanese IT giant Broadleaf. At the same time, Broadleaf has also obtained a license to supply Shelf.Network technology to establish a trading network for automobile and parts sales in Southeast Asian countries (including Japan, Myanmar, Thailand, Indonesia, Vietnam, Laos, Australia, India and Singapore).

By the end of 2018, 60,000 vehicles from the United States had joined the service network. Shelf.Network also implements interaction with the Carfax web service, through which vehicle history reports can be provided to individuals and businesses. For example, when startup Auto1 Group GmbH buys cars in Germany, loan and insurance products are recorded via blockchain, which greatly speeds up transactions (which would have taken two weeks to complete with traditional paperwork).

A survey of large companies conducted by the IBM Institute for Business Value shows that by 2021, blockchain will play a key role in the automotive industry, and at the same time, blockchain will also be used in the aviation field . For example, S7 Airlines and Alfa Bank (Russia) have enabled real-time payments for aircraft fuel costs by applying smart contracts on the Hyperledger blockchain platform.

All walks of life in the industry believe that DLT technology can simplify and speed up mutual settlement processes, eliminate various financial risks, and automate processes. As in the field of wholesale logistics, this technology also has important application significance in the field of transportation.

Blockchain technology is also gradually penetrating into the public sector and is widely used in document authentication processes. For example, the Proofstack service is able to archive files with the owner’s personal signature, date and time stamp, and then writes the archive hash to the blockchain. Users can also select the country that affects the type of timestamp, as well as the storage location (computer, cloud) required to generate the archive. Created archives allow people to identify when and by whom a file was archived. At the same time, the application of blockchain in the judicial system is becoming more and more popular. For example, ServeManager and Integra have applied blockchain technology to services that track subpoena delivery.

In China, government-backed blockchain solutions continue to develop rapidly. Its judicial blockchain system "Tianping Chain" has collected about 1 million pieces of online evidence data just three months after its release. All materials submitted on the platform are DLT certified, totaling 190,000 documents. The platform electronic evidence system was jointly developed by the Beijing Internet Court, the China Industrial Control System Emergency Response Team (CICS-CERT), the Research Center of the Ministry of Industry and Information Technology, the Network Internet Group and the TrustDo blockchain startup. The platform is based on the hyperchain infrastructure of the Internet giant network, optimizes the evidence collection and storage process, and ensures the authenticity of the data through the blockchain. In addition, the platform also achieves the purpose of saving time and resources by reducing Internet-related litigation costs.

As a global leader in container shipping, Maersk began using Insurwave blockchain solutions last spring. The marine insurance platform was jointly developed by consulting firms EY and Guardtime and is based on Microsoft Azure cloud technology. In the first year of cooperation with Insurwave, Maersk plans to insure 1,000 ocean-going vessels, and the total number of digital transactions will exceed 500,000.

Currently, platform users include Willis Towers Watson,XL Catlin and MS Amlin. Developers are trying to expand Insurwave's capabilities to expand insurance into the aviation and energy sectors.

Calastone, a British financial technology company specializing in investment flow management, announced that it will transfer all calculations to the blockchain. The company expects the technology to help cut billions of dollars in costs across its global settlement division. Calastone provides risk assessment management services, IT infrastructure and payment solutions to more than 1,700 companies, with clients including JP Morgan Asset Management, Schroders and Invesco.

If the enterprise's goal is to achieve transparency of transactions and information entered into the DLT registry, this will create an excellent application scenario for blockchain; however, if the enterprise is pursuing anonymity or "tracking "In financial transactions, there is no opportunity for blockchain to exert its influence.

Singapore Power Group has launched a blockchain trading market for renewable energy (REC) certificates. Its company representatives said the "in-house developed" platform was designed to improve the security, reliability and traceability of such certificate transactions.

REC certificates are certificates that certify the amount of energy released by solar panels and are sold by Cleantech Solar Asia and LYS Energy Solutions. City Developments Limited and DBS Bank, who are interested in purchasing certificates, are both very interested in the platform. Katoen Natie Singapore has also joined the platform and plans to launch renewable electricity production capacity soon.

KT Corporation, South Korea’s largest telecommunications company, has also launched its own blockchain network, with distributed registration technology involving user authentication and improving international roaming services. This enables KT to securely transfer customer data to its partners. Network bandwidth can handle 100,000 transactions per second.

Time will tell whether these initiatives gain mass market acceptance. Likewise, the applications of blockchain in power, data, and user-identified accounts/records/transactions are old news.

At the end of 2017, the Massachusetts Institute of Technology (MIT) used the Blockcerts wallet, which can issue a "verifiable, tamper-proof" authentication certificate, to more than a hundred people through the Bitcoin blockchain. Graduates were issued digital diplomas.

The pilot project is supported by software company Learning Machine, which has worked with Media Lab participated in the research and development of Blockcerts together.

The purpose of this is to allow students to become the true owners of their own files. Learning Machine CEO Chris Jagers said that even if the agency ceases to exist, people will be able to extract important official information stored in it.

The same approach is used by Tbilisi University of Business and Technology: the university uses a similar blockchain platform, Trusted Diploma, through a partnership with Emercoin. The platform is able to restore registration data (subjects studied, quality of training and scores obtained) with the help of blockchain. From this point of view, in the future, blockchain may be useful in further promoting digital learning methods.

⑧ Can spacecraft use artificial intelligence and blockchain to respond to crises autonomously

This type of technology is crucial to space exploration in the next few decades. important. As NASA is planning a mission to explore Centauri and beyond as early as 2069, unmanned spacecraft that can think about and respond to their surroundings autonomously will help ensure that humans can collect information in deep space far away from the earth. ability. Space presents many unexpected challenges, and this research helps spacecraft reach their destinations unscathed.
