Blockchain is attracting more and more attention to its applicability in the fields of Internet of Things (IoT). In particular, it is able to store data in unalterable blocks, associated with its secure peer-to-peer in a growing problem of transaction authorization in industrial and service provisioning applications. Moreover, it facilitates decentralized transaction (TX) validation and distributed ledger. The underneath algorithm of TX selection for validation may not be effective in terms of delay of various services of the applications. Because the existing random-based or fee-based selections are a delay insensitive that does not guarantee a minimum delay of a time-critical TX. This paper proposes a blockchain-based transaction validation protocol for a secure distributed IoT network. It includes a context-aware TX validation technique, where a TX is validated by a miner with the priority of a service. Besides, we adopt the Software Defined Networking enabled gateway as a middleware between IoT and the blockchain network in which the control operations and security of the network in a largescale are ensured. The proposed network model has evaluated and compared to the Core network. The results ensure the given priority in TX validation is more delay sensitive than the existing technique to provide quality of service of the network.
