Research On Organization Collaboration Blockchain

In the information age,more and more organizations collaborate with other organizations through information system.Because some organizations will fake and deny the collaboration activities during the collaboration period,which has a negative impact on the trust among organizations,improving the security during the collaboration period is an important research content in the field of network security.The traditional approach is to introduce a third-party organization for supervision,but this mode has the risk of a single point of issue.As a technology with decentralized and immutable characteristics,blockchain technology can largely alleviate the problems of traditional methods.Based on this,this thesis conducts research on organization collaboration blockchain.First of all,considering the lack of a standard to describe the data representation of organization collaboration,this thesis analyzes the abstract behavior of organization collaboration with the elements provided by wetoband,and defines six kinds of collaboration activities and related log formats,which are: resource publishing,resource receiving,position publishing,post fetching,local resource collaboration and external resource collaboration.Then,considering the current open source blockchain's under optimization of organization collaboration scenarios,this thesis designs and implements a blockchain prototype system organization collaboration chain.Organization collaboration chain provides the functions of collaboration log collection,accounting and neutral statistical form generation.In order to provide better accounting performance,the organization collaboration chain will be based on asynchronous accounting.At the same time,the related entities of organization collaboration chain will be designed according to the characteristics of collaborative activities.The organization collaboration chain is finally divided into seven modules: log collection module,consensus module,transaction pool module,block pool module,block generation module,block execution module and form generation module.Finally,this thesis conducts simulation test and performance test on the organization collaboration chain.The test results show that the related functions of organization collaboration chain are consistent with the expected results,and to a certain extent,it can avoid the organization's fraud and denial of collaborative activities.At the same time,the organization collaboration chain shows higher accounting TPS performance than the open source blockchain system Hyperledger Fabric in the test environment.
