Through blockchain Technology

1. blockchain does not belong to any instry. Blockchain is a new application mode of computer technology, such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and so on. 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.

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

3. A: blockchain technology has been applied in many fields
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 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
Third, 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
IV. 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
in terms of insurance claims, insurance institutions are responsible for fund collection, investment and claims settlement, and often have higher management and operation costs< 6. In the field of public welfare, the data stored on the blockchain is highly reliable and tamperable, which is naturally suitable for social public welfare scenarios.

4. Take laikelib, a project launched by Shanghai Heshu software, a blockchain company, as an example. Through blockchain and big data technology, we can eliminate the defects of traditional network mutual aid mode and establish a new open and transparent network application development platform
the technical characteristics of the blockchain determine that the underlying framework of laikelib blockchain technology has the following characteristics:
first, independent research and development. Anyone can develop their own applications on the chain; Moreover, all capital flows are open and transparent, and can not be forged or tampered with. Every user can exercise the right of supervision; Second, it's easy to be small. The time of block extraction is short. The transfer of all funds can only be carried out in accordance with the open smart contract, and there is no legal person for misappropriation and intervention; Finally, each user's personal sensitive information will be highly encrypted, and no one else can access it.

5. In one word, this paper introces the blockchain technology, that is, through consensus mechanism, cryptography and distributed multi ledger, to form a multi-party shared, tamper proof, time stamped information chain and transaction chain.

6. Take the first project of concentric mutual aid launched by the blockchain start-up company Abbott Financial Technology Co., Ltd. as an example, through blockchain and big data technology, we can eliminate the defects of traditional network mutual aid mode and establish a new open and transparent network mutual aid platform
e to the technical characteristics of blockchain, concentric mutual aid has three characteristics:
first of all, all capital flows are open and transparent, which can not be forged or tampered with, and each user can exercise the right of supervision
secondly, the transfer of all funds can only be carried out in accordance with the open smart contract, and there is no legal person for misappropriation and intervention
finally, each user's personal sensitive information will be highly encrypted, and other people can't access it
based on the above three points, the problems existing in the traditional network mutual assistance mode have been solved one by one.
