Embodiment Construction

[0090] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0091] On the one hand, this embodiment provides a data sharing incentive model (EGDSI model) based on evolutionary game theory, including:

[0092] The form of a binary group M=(P, K), where P represents a population composed of users of a large number of data sharing communities; K is the strategy space K={K 1 , K 2}, the user has two strategies, one is K 1 Participate in data sharing, that is, in the data sharing community, actively contribute your own data and obtain the data of other sharing users; the other is to choose not to parameterize the sharing strategy K 2 , will neither share data nor obtain shared data from the community.

[0093] The second aspect of t...

Abstract

The invention discloses a data sharing incentive model based on an evolutionary game theory, and the model comprises a two-tuple form M = (P, K), and P represents a population composed of a large number of users of a data sharing community; k is a strategy space K = {K1, K2}, the user has two strategies, one is that K1 participates in data sharing, that is, in a data sharing community, self data is actively contributed, and data of other sharing users can be obtained; the other method is to select a non-parameter sharing strategy K2, so that data cannot be shared, and shared data cannot be acquired from a community; the method for establishing the model comprises the following steps of: 1, designing mathematical model parameters; 2, deriving a plurality of evolutionary game stabilization strategies by applying a replicated dynamic mechanical equation of an evolutionary game theory; and step 3, performing stability analysis on the plurality of evolutionary game stability strategies, deducing an excitation condition use method of the data sharing excitation model, and obtaining an optimized data sharing excitation model based on the evolutionary game theory.

Description

technical field [0001] The invention belongs to the technical field of blockchain smart contracts, and in particular relates to a data sharing incentive model based on evolutionary game theory and a method for establishing the same. Background technique [0002] At present, data trading platforms generally have a low degree of data sharing, and users are not very willing to share data. This is due to the lack of trust among users, and the lack of corresponding incentive mechanisms and economic interests. The blockchain has the characteristics of decentralization and non-tampering, and these characteristics provide new solutions for solving social trust problems. [0003] The purpose of data sharing is to maximize the value of data, realize the circulation of data value, and form a virtuous circle. However, whether it is my country or Europe and other developed countries, the degree of data sharing is still low. The main factor hindering data sharing is that users worry tha...
