Blockchain technology provides a distributed trust and allocated ledger for the Internet of Things (IoT) solutions and edge computing applications. It is also an effective method for Industry 4.0 in cloud computing and business process management. This paper proposes a Blockchain-as-a-Service (BaaS) solution based on an open-source enterprise-grade permissioned distributed ledger technology (DLT) Hyperledger Fabric (HLF) and integration with a web-based implementation mechanism for IoT. The framework for building and creating proposed enterprise-grade Blockchain solutions using HLF protocol consists of five layers: device layer, network layer, middleware layer, service support layer and application layer. Also, HLF protocol, through developed Smart Contracts, helps address major security requirements and solve most of the architectural shortcomings of IoT with its “security by design” architecture. A RAFT consensus algorithm and a dynamic trust-suitable algorithm are used with created Smart Contracts to improve the Blockchain’s transaction latency and throughput and reduce the number of transactions validated in new blocks. This paper analyses the main challenges the research community faces in smoothly integrating HLF Blockchain protocol and IoT and presents an observation about novel uses of HLF protocol in the machine economy through exposed Representational State Transfer Application Programming Interface (REST API) endpoints. Finally, the paper presents Blockchain framework and performance experiments with meta-data that indicate that the method performs well in IoT edge applications.Computerized Management System (CMS)Decentralised Digital Management Systems (DDMS)BlockchainHyperledger FabricSmart ContractInternet of Things (IoT)Message Queue Telemetry Transport (MQTT)Distributed Ledger Technology (DLT)Golang Programming LanguageConference Presentation
