Main problems of blockchain application

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. 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.

3. I choose Chinese currency! Low operation delay, idle can also save money mining EOS, very suitable.

4. Blockchain solves the problem of trust, which is the root of all problems
wikilink is a complete intelligent contract platform supporting Turing. Wikilink adopts the consensus mechanism of dpos, with a total of 11 voting nodes, generating a new block every 10 seconds. Through the smart contract wikilink, we can realize a wealth of application scenarios, such as asset issuance, guessing applications, right traceability, mutual insurance, decentralized exchanges, cross-border settlement, etc
but the most important thing in these scenarios is trust, which is to be open and transparent.

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. In one sentence, it is decentralization. Blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system. In a narrow sense, blockchain is a kind of chain data structure that combines data blocks in a sequential way according to the time sequence, and it is a distributed account book that can not be tampered with and forged by means of cryptography. In a broad sense, blockchain technology is a new distributed infrastructure and computing method, which uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses intelligent contract composed of automated script code to program and operate data. Advantages: 1) the algorithm is simple and easy to implement; 2) There is no need to exchange additional information between nodes to reach a consensus; 3) It costs a lot to destroy the system. Disadvantages: 1) waste of energy; 2) It is difficult to shorten the block confirmation time; 3) The new blockchain must find a different hash algorithm, otherwise it will face bitcoin attack; 4) It is easy to proce bifurcation and needs to wait for multiple confirmations; 5) There is never finality, and checkpoint mechanism is needed to make up for it.

7. Potentially disappointing applications: digital procts such as music and games
I'm afraid that many people have seen such news and some companies are doing such projects by using the transparency of blockchain to solve the problems of the music instry. But have you ever thought about using blockchain to make music? Is it really necessary for the audience

the emergence of streaming media has spoiled the audience. Although musicians are against this mode, almost all technology giants have deployed streaming media. The emergence of this mode makes it difficult for the traditional physical record mode to turn over. Big brands such as Taylor swift and Adele refuse to cooperate with streaming media platform in order to promote record sales, But in the eyes of streaming media managers like music tank, this refusal is only temporary. In the final analysis, musicians feel that they have made less money and are aggrieved. The key point is that the audience pays less. Do users care about the income of the musicians
here we emphasize a problem. Blockchain can only solve the problem of falsification, but it can't solve the problem of piracy. It's very easy to pirate music and other digital procts
of course, it's not that there is no possibility of success. I just say that there will be a lot of resistance to this kind of application, and users will not like it. Only musicians will have the motivation to promote it. On the other hand, for trading users, blockchain can provide transparency, and it can also bring efficiency and cost advantages to the exchange, so its resistance is relatively small
blockchain will have a profound impact on finance, logistics, crowdfunding (European crowdfunding), certification and securities.

8. Most business development needs to establish a certain trust foundation, especially in the cross agent scenario. Blockchain can provide very effective help for application scenarios with difficult trust establishment and high trust maintenance cost.
