2. blockchain application fields:
1. Financial field. Blockchain has great potential application value in international exchange, letter of credit, equity registration, stock exchange and other financial fields. The application of blockchain technology in the financial instry can save the third-party intermediary link and realize the point-to-point direct docking, so as to greatly rece the cost and quickly complete the transaction payment< 2. Internet of things and logistics. Blockchain can also be naturally combined in the field of Internet of things and logistics. Through blockchain, we can rece logistics costs, trace the proction and delivery process of goods, and improve the efficiency of supply chain management. This field is considered as a promising application direction of blockchain

3. Public service. Blockchain is closely related to people's proction and life in public management, energy, transportation and other fields, but the centralization of these fields also brings some problems, which can be transformed by blockchain. The decentralized and fully distributed DNS service provided by the blockchain can realize domain name query and resolution through the point-to-point data transmission service between nodes in the network. It can be used to ensure that the operating system and firmware of an important infrastructure have not been tampered with. It can monitor the status and integrity of the software and detect bad tampering, And ensure that the data transmitted by the system using the Internet of things technology has not been tampered with< 4. Digital rights. Through blockchain technology, works can be authenticated to prove the existence of text, video, audio and other works, and ensure the authenticity and uniqueness of ownership. After the works are confirmed on the blockchain, the subsequent transactions will be recorded in real time to realize the full life cycle management of digital rights, and can also be used as a technical guarantee in judicial evidence collection. For example, mine labs, a start-up company in New York, developed a metadata protocol based on blockchain. This system called mediachain uses IPFs file system to realize right protection of digital works, mainly for right protection applications of digital pictures

5. Insurance. In terms of insurance claims, insurance institutions are responsible for fund collection, investment and claims settlement, and often have higher management and operation costs. Through the application of smart contract, there is no need for the applicant to apply or the insurance company to approve. As long as the claim conditions are triggered, the automatic claim settlement of the policy can be realized. A typical application case is lenderbot, which was launched by the blockchain enterprise stratumdeloitte and payment service provider lemonway in 2016. It allows people to register customized micro insurance procts through the chat function of Facebook messenger to insure the high value items exchanged between indivials, and the blockchain replaces the third party role in the loan contract< 6. Public welfare. The data stored on the blockchain is highly reliable and tamperable, which is naturally suitable for social public welfare scenarios. The relevant information in the public welfare process, such as donation project, collection details, fund flow, recipient feedback, etc., can be stored on the blockchain, and can be made transparent and public, which is convenient for social supervision.

3. Alarm processing is OK. Don't believe what can be chased back
this is a liar. It's like this every day
do you think he's Lei Feng
he's better than the Public Security Bureau. Will he still be here

4. One of the characteristics of blockchain is to realize irreversibility through distributed ledger technology, and at the same time, various technologies such as ring signature and zero knowledge proof are used to realize anonymity and privacy protection. Social networks are monopolized by Facebook, instant messaging is monopolized by WhatsApp and other centralized procts. They bring incomparable communication convenience to users, greatly improve the frequency and efficiency of communication between people, and bring convenience to billions of people all over the world

through the blockchain, communication services can organize the operation of communication services without the mode of central enterprise. In the future, blockchain should have a real impact on real life, not just by concept and hype, but by real landing procts. What is really landing procts is procts that can meet the needs of users. If the existing centralized procts can well meet the needs of users, then the decentralized procts will not have enough substitution effect, and can not be truly implemented

the protocol layer of blockchain mainly includes four aspects: network programming, distributed algorithm, encrypted signature and data storage technology
the ability of network programming is the main factor for us to choose a programming language, because distributed algorithm is basically the implementation of business logic and can be achieved in any language. The encryption signature technology is directly and simply used, and the database technology is mainly used. Only the implementation of point-to-point network and concurrent processing is the difficulty of development. Therefore, for those languages with strong network programming ability and simple concurrency processing, people especially prefer them

users get the initial number of tokens for free. Some of its practical use scenarios:
1. Encrypted video chat: multinational users want to have video chat, only when both sides hold a certain number of SKM can they achieve encrypted video chat
2. Large capacity file encrypted transmission: the file transmitted by one user to another user exceeds the size limit, and the sender must hold a certain token to realize encrypted transmission
3. Conversation information saving: conversation records can be saved as long as both parties agree, and both parties need to hold a certain amount of tokens
4. Retransmission reminder: if a user sends a file to another user, but he doesn't want the other user to share it, the user can use a certain token to be notified when the file is retransmitted
5. Secret key unlock file: one user transfers the secret key file to another, and only the other party is allowed to view it. The sending user can use the token to let the other party receive the fragmented file. Only by getting the secret key from the sender can the file be unlocked<

the Xueshuo innovation blockchain Technology Workstation of Lianqiao ecation online is the only approved "blockchain Technology Specialty" pilot workstation of "smart learning workshop 2020 Xueshuo innovation workstation" launched by the school planning, construction and development center of the Ministry of ecation of China. Based on providing diversified growth paths for students, the professional station promotes the reform of the training mode of the combination of professional degree research, proction, learning and research, and constructs the applied and compound talent training system.

5. I also met the same problem. I was cheated into buying payc. I couldn't get on the live studio tonight. I couldn't get in touch with Jinchan and Tiantian. There was no reply. What should I do next? I hope to get some advice.

6. The trial quotient method of divisor is a two digit division
1; Pithy formula test business&# 8194;
divisor is the division of the whole ten. Generally speaking, you can use the formula to test the quotient directly
Second, "round off" method&# 8194;
"rounding" method is the most common method and the most widely used method, which can be said to be the general method of trial quotient
Third, half estimate 5&# 8194;
when the first two digits of the divisor are equal to or close to half of the divisor, the initial quotient can be set as 5
four, the same head is not enough business 8, 9&# 8194;
when the first two digits of the divisor are the same as the number on the highest digit of the divisor's two digits, it is the same header< 5. Try in high position and adjust in low position&# 8194;
divisor is a two digit number, and the first two digits of the divisor are considered< 6. Test quotient of divisor 25
master the multiple of 25, so you can get the quotient quickly.

7. You'd better go to the police station and ask the real police uncle. Now there are many swindlers who take personal information to borrow money.
