A research method and system based on block chain

Abstract

The invention relates to the technical field of block chain, intelligent contract and user investigation, in particular to an investigation method and system based on block chain. The invention discloses a research method based on block chain, which utilizes block chain and intelligent contract technology, realizes the decentralized data and reward exchange process, realizes double blindness between the researcher and the investigated, ensures the credibility of the research data, and protects the personal privacy of the user. The invention also provides a research system based on a block chain, comprising a client, a research system, an intelligent contract and a distributed general ledger.

Description

technical field [0001] The present invention relates to the technical fields of block chain technology, smart contracts and user research, and in particular to a block chain-based research method and system. Background technique [0002] Blockchain technology, blockchain is a new type of decentralized distributed ledger technology, which is essentially a decentralized database that can safely store digital currency transactions or other data. Information cannot be forged and tampered with. The blockchain consensus algorithm drives every node on the blockchain to participate in the transaction verification process, ensuring that transactions on the blockchain are confirmed and credible. Every node on the blockchain All maintain a public account book, which is used to store the balance and smart contract data of all users on the blockchain network. Any modification of the account book maintained by any node will not be recognized by other nodes, thus ensuring that the public a...

Problems solved by technology

The main problems of the existing technology are: firstly, it is difficult to ensure the double-blindness of the survey, because the corresponding rewards must be paid to an anonymous participant, and currently all online payment methods need to know the participant’s online account except for virtual currencies such as Bitcoin. The account information is related to the personal information of the participants, and it is difficult for third-party agencies to guarantee that personal information will not be leaked; secondly, the participants will be skeptical about the survey compensation, because there are many cases of online fraud in today's society, and people are not interested in online surveys. There will be vigilance, and will worry about personal information leakage or even being cheated of money

[0005] The Chinese patent application number 201310034232.4 discloses an electronic questionnaire survey business system and a survey method using the business system. It fills in electronic questionnaires for interviewees through electronic terminals and directly uploads the questionnaire results to the server, improving the efficiency of questionnaire surveys. efficiency, optimize the management of questionnaires, and prevent researchers from cheating during the research process, but its disadvantage is that it lacks the protection of the personal information of the respondents. The personal information of the respondents is directly uploaded to the server through the electronic terminal. During the process of uploading information There is a risk of information leakage or malicious theft

[0006] The Chinese patent application number 201710021250.7 discloses an Internet-based market research system and its processing method, which realizes intelligent Internet-based market research, reduces labor intensity, saves manpower, and is not restricted by region, time and space. The scope of the survey is larger, but its disadvantage is that it does not pay certain remuneration for the survey participants, and the authenticity and reliability of the survey data obtained are low
