Trusting Testcases Using Blockchain-Based Repository Approach

Abdulla Al Zaabi, Chan Yeob Yeun, Ernesto Damiani
2021 Symmetry  
In this paper, we propose a blockchain-based approach for a testcase repository to support test-based software and security testing and overcome the lack of trusted testcase repositories.  ...  The original vehicular ad-hoc network term is now emerged to a new term, Internet of Vehicles (IoV), which is a typical application of symmetry of Internet of Things (IoT).  ...  A peer in the Fabric is responsible for validating transactions and maintaining the state of the ledger, and it can also have a special role called the endorser.  ...
