5. What are the applications of blockchain technology?

Blockchain has become so popular, so what are the application fields of blockchain?

At present, the most extensive and successful application of blockchain technology is the digital currency represented by Bitcoin. Digital currency has developed rapidly in recent years. Due to the characteristics of decentralized credit and frequent transactions, it has a high transaction value and can maintain a relatively stable price through the development of hedging financial derivatives as a quasi-super-sovereign currency.

Financial institutions are the most willing to explore blockchain applications and need new technologies to improve operational efficiency and reduce costs to cope with the current status of the entire global economy. Objectively speaking, the market space in the financial industry is huge, and a little progress can bring huge benefits. The financial industry is an industry with extremely high requirements for security and stability. If the application of blockchain in the financial field is verified, it will have a huge demonstration effect and be quickly promoted in other industries. In the financial field, in addition to digital currency applications, blockchain has gradually begun to be applied in cross-border payments, supply chain finance, insurance, digital bills, asset securitization, bank credit reporting and other fields.

As the application of blockchain technology in the financial field continues to be verified, its technical advantages are gradually showing value in other industries. At present, blockchain application projects are gradually being implemented in fields such as medical and health, IP copyright, education, culture and entertainment, communications, charity, social management, sharing economy, and the Internet of Things, and "blockchain" is becoming a reality.

(1) Blockchain medical care: In the medical field, blockchain can use its anonymity, decentralization and other characteristics to protect patient privacy. Electronic health (EHR), DNA wallet, drug anti-counterfeiting, etc. are all possible application areas of blockchain technology. IBM predicted in last year's report that 56% of medical institutions around the world will invest in blockchain technology by 2020.

(2) Blockchain Internet of Things: The Internet of Things is a very broad concept. If communications, energy management, supply chain management, sharing economy, etc. are included, the Internet of Things with blockchain technology Application will become a very important application field.

(3) Blockchain IP copyright & cultural entertainment: Since the Internet became popular, digital music, digital books, digital videos, digital games, etc. have gradually become mainstream. The rise of the knowledge economy has made intellectual property rights a core element of market competition. However, intellectual property infringement is serious in the current Internet ecosystem, and the copyright protection of digital assets has become a pain point in the industry. Blockchain features disintermediation, consensus mechanism, and non-tamperability. Blockchain technology can effectively integrate all aspects of the cultural and entertainment value chain, accelerate circulation, and shorten the value creation cycle; at the same time,, can realize the value transfer of digital content, ensure the credibility, auditability and transparency of the transfer process, and effectively prevent piracy and other behaviors. Blockchain Public Services & Education: In the fields of public services, education, charity and public welfare, issues such as file management, identity (qualification) certification, and public trust all exist objectively. The traditional method is to rely on third parties with credibility. The company makes credit endorsements, but problems such as fraud and deficiencies still exist.

6. What are the possible application fields of blockchain? What are the application fields of blockchain technology?

1. Financial field. Blockchain has potentially huge application value in financial fields such as international exchange, letters of credit, equity registration and stock exchanges. The application of blockchain technology in the financial industry can eliminate the need for third-party intermediaries and achieve direct point-to-point connection, thereby greatly reducing costs and quickly completing transaction payments.

2. Internet of Things and logistics fields. Blockchain can also be naturally combined in the Internet of Things and logistics fields. Through blockchain, logistics costs can be reduced, the production and delivery process of items can be traced, and the efficiency of supply chain management can be improved. This field is considered to be a promising application direction of blockchain.

7. What exactly does blockchain refer to, and what disciplines or fields does it involve?

What is blockchain? Blockchain applications mainly include Internet technology and information content encryption algorithms, combined with appropriate rules and systems, to form a reliable system software infrastructure. The infrastructure here can be interpreted as the online environment. What does this trust mean? Database encryption methods can be divided into symmetric encryption algorithms and symmetric encryption. Symmetric encryption has higher security, but slower response speed. The elliptic curve encryption technology used in blockchain technology is the fastest method among non-asymmetric encryption algorithms. Therefore, the encryption algorithm of blockchain technology is very powerful and it can ensure the uniqueness of the customer's identity. In addition, the information in blockchain technology is also protected by data encryption and is difficult to forge.

The blockchain system avoids the above three problems. The behavior of each node is different from other nodes. The behavior of the node is determined by the program in advance. The regulations are stipulated, and the encryption algorithm ensures that every connection point cannot violate the regulations. This is the connotation of grassroots democracy in the system. Blockchain applications are generally used to build trading software, and it is necessary to ensure that the transaction information content is authentic, valid, traceable and cannot be tampered with. Each transaction information is verified and stored in a zone, and the blockchain information is encrypted through hashing technology to ensure that the information cannot be forged. This blockchain forms a transmission chain in chronological order. Each node has complete blockchain information. If the information content of some nodes is destroyed, the blockchain information will not be affected. This type of archival information method is called a distributed ledger.

In such a distributed ledger of blockchain technology, a new record is added and associated with all nodes.The actual operation of points must be carried out according to certain rules, otherwise nothing can be said to be true and effective. This standard is the consensus mechanism of blockchain technology. In essence, a fair and equitable consensus mechanism should allow all nodes to improve the blockchain. When the contents of the added blockchains are different, they should be negotiated according to certain standards until the contents of a certain blockchain are accepted, and then all nodes will copy this blockchain. Instead of equalizing the amount, not all nodes can be added to the blockchain. Instead, a point eligible to be added to the new server block is selected based on certain criteria and the blockchain information added by the node is copied. Blockchain technology uses the latter, and since the election rules are open and transparent, the election ceremony will become the entire competition process.
