PlaTIBART: a Platform for Transactive IoT Blockchain Applications with Repeatable Testing

Abstract

With the advent of blockchain-enabled IoT applications, there is an increased\nneed for related software patterns, middleware concepts, and testing practices\nto ensure adequate quality and productivity. IoT and blockchain each provide\ndifferent design goals, concepts, and practices that must be integrated,\nincluding the distributed actor model and fault tolerance from IoT and\ntransactive information integrity over untrustworthy sources from blockchain.\nBoth IoT and blockchain are emerging technologies and both lack codified\npatterns and practices for development of applications when combined. This\npaper describes PlaTIBART, which is a platform for transactive IoT blockchain\napplications with repeatable testing that combines the Actor pattern (which is\na commonly used model of computation in IoT) together with a custom Domain\nSpecific Language (DSL) and test network management tools. We show how\nPlaTIBART has been applied to develop, test, and analyze fault-tolerant IoT\nblockchain applications.\n
