Abstract	Smart cities are built on top of Internet of Things (IoT)-based networks, with the aim of improving the quality of life for their citizens and urban surroundings through the provision of smart solutions across numerous applications with streamlined communications. However, due to the complexity of devices involved in forming IoT networks, especially sensors, which play an important role in data acquisition and collecting sensitive information. However, there are various security threats and privacy issues with the smart city infrastructure and the processing of data. Moreover, due to the heterogeneous nature of devices and a lack of suitable security mechanisms and deployment scenarios, traditional security mechanisms are not feasible in the IoT spectrum. Also, the inclusion of malicious nodes and tampered data not only reduces the quality of service but also degrades the network's performance and lifetime. Blockchain, with its decentralized nature and distributed design, can play a significant role in securing IoT-based networks, specifically by providing trustworthy mechanisms for data acquisition. To this end, in this paper, we propose a distributed blockchain-based trustworthy scheme (DBTS) for a network of untrusted Internet of Things (IoT) devices. The suggested approach incorporates smart contracts into heterogeneous Internet of Things (IoT) networks to verify data's veracity. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.
