Blockchain can be used in

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. 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.

4. 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;

5. What's your calculation power? Now, if you don't have 100g computing power, don't dig bitcoin. The money is not so easy to earn. And the difficulty of mining increases by 20% every 14 days

6. Blockchain technology can be applied to many fields and scenarios, so we need to further broaden the vision of research and development of blockchain technology. Including some scenarios in the field of social management, Domenech jewelry in the future will focus on the practical application scenario of using technology at the bottom of blockchain to promote the combination of blockchain and real business

7. Blockchain is a decentralized distributed ledger, which is composed of unchangeable data packets. These data packets are also called "blocks", and each block is connected to form a "blockchain". It is a technical solution to collectively maintain a reliable database through decentralization and distrust. Each block is connected to the previous block to form a block chain.
