Abstract： With the sustained development of big data,data collection and sharing are highly valued,resulting in a large number of data exchange platforms. However,most platforms focus on data security and user privacy,but neglecting the issue of users′ willingness for exchange. In practical applications,users often have little willingness to exchange due to a lack of sufficient motivation. In response to this issue,this article constructed a blockchain based data exchange incentive framework and proposed a data exchange incentive mechanism based on historical contribution and current contribution. On the one hand,it considers users′ past performance from the historical dimension. On the other hand,it considers users′ realtime contributions from the current dimension. The article conducted theoretical analysis and experimental evaluation for the proposed method,and the results show that the incentive mechanism can effectively motivate users to engage in positive data exchange in the long term.
Key words : blockchain; data exchange; incentive mechanism; historical contribution; current contribution
