Where is blockchain technology mainly used

1.

I have seen your question. In which aspects can blockchain be applied? Below by the small series to answer for you

bitcoin is the first specific application of blockchain. It was proposed in a paper by one person or a group of people in 2008. Bitcoin uses blockchain to send digital messages to bitcoin, and the name of bitcoin is bitcoin, without the intervention of a third party middleman

However, bitcoin is not the only application of blockchain, as follows:

1. Financial field: the application of blockchain technology in the financial instry can eliminate the third-party intermediary link, 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

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

4. In the field of digital right: 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

5. In the field 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

6. Public welfare field: 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

the above is for your reference only, hope you can adopt it, thank you

2. Blockchain is not a single technology, but the result of the integration of a variety of technologies. These technologies are combined with a new structure to form a new way of data recording, storage and expression.

3.

From the perspective of technology and architecture, I will tell you my understanding of blockchain in common language

what is blockchain? In a word, blockchain is a storage system. To be more specific, blockchain is a distributed storage system without an administrator and each node has all the data

What are the common storage systems like

as shown in the figure above, the bottom is data, and the top can write data. A space to store data, a software to manage data, provide an interface to write data, this is the storage system. For example, MySQL is the most common storage system

What are the problems of ordinary storage system? There are at least two common problems

the first is the problem of non high availability. There is a dangerous place for data. In technical terms, data is not highly available

The second problem is that there is only one write point. In technical terms, it is a single point of control

How do ordinary storage systems usually solve these two problems

in fact, MySQL can do a master-slave synchronization of al master, master-slave synchronization of al master, two nodes can be written at the same time. If you want to do a multi room multi live data center, in fact, multi room multi live data synchronization. What we should emphasize here is that multi-point writing often leads to the consistency problem of writing conflicts. Take MySQL as an example, suppose that the attribute of a table is self incrementing ID, then the data in the database is 1234 now. If one of the nodes writes and inserts a piece of data, it may become 5, and then these 5 pieces of data are synchronized to another master node, Before synchronization, if another write node inserts a piece of data, a piece of data with self incrementing ID of 5 will be generated. Then, after the generation, synchronize to another node, and the synchronized data will conflict with the two local 5's after it arrives, which will lead to synchronization failure and write consistency conflict. This problem will occur in the case of multi-point writing

how to ensure consistency in multi-point writing

4. The core advantage of blockchain technology is decentralization. It can realize point-to-point transaction, coordination and cooperation based on decentralized credit in a distributed system without mutual trust by means of data encryption, time stamp, distributed consensus and economic incentive, so as to solve the common high cost, low cost and low cost of centralized institutions Low efficiency and data storage insecurity provide solutions
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry
taking the tourism instry as an example, blockchain applications mainly focus on tourism travel, tourism community reviews, digital identity management, credit consumption management, tracking pilot's professional certificate and qualification, loyalty plan of hotels and airlines, reservation management and consumption points management. In addition, blockchain also has applications in finance, games, entertainment and other fields.

A: application fields of blockchain technology

I. financial field

blockchain has great potential application value in international exchange, letter of credit, equity registration, stock exchange and other financial fields

Second, the Internet of things and logistics

blockchain can also be naturally combined in the field of Internet of things and logistics

through the blockchain, we can rece the logistics cost, trace the proction and transportation process of goods, and improve the efficiency of supply chain management

Third, in the field of public service, blockchain is closely related to people's proction and life in the fields of public management, energy and transportation. However, the centralization of these fields also brings some problems, which can be transformed by blockchain

Fourthly, in the field of digital right, 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

In the field of insurance, insurance institutions are responsible for fund collection, investment and claim settlement, and often have higher management and operation costs

Sixth, the data stored on the public welfare field

blockchain is highly reliable and tamperable, which is naturally suitable for social public welfare scenarios

6. Blockchain is the core supporting technology of digital cryptocurrency system represented by bitcoin. The core advantage of blockchain technology is decentralization. It can realize point-to-point transaction, coordination and cooperation based on decentralized credit in a distributed system without mutual trust by means of data encryption, time stamp, distributed consensus and economic incentive, so as to solve the common high cost, low cost and low cost of centralized institutions Low efficiency and data storage insecurity provide solutions
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry.

7. Qube exchange answers for you:
to apply blockchain, we must first understand the characteristics of blockchain: decentralization, openness, autonomy, non tampering information and anonymity
it is of great benefit to the following instries:
1. Art investment
using blockchain technology, we can track the source of art. Because every transaction has a digital certificate, and is unique, avoid black market transactions
2. Literary works
because blockchain is traceable, it can avoid the occurrence of piracy. Once a work is created, later people can it, and you can find it immediately
3. Finance
some financial payment and clearing systems are imperfect, especially cross-border payment. Blockchain is not only an information registration system, but also a payment system. Therefore, the account book can not be modified and open, so that it can serve the financial market;
