Abstract	Smart city architecture development has become a significant research domain. Internet of Things (IoT) has become a principal element in the development of the smart paradigm. However, data security is a primary concern here as a massive amount of data collection is involved. In the field of data security, blockchain is a key technology today. In this paper, we have proposed a blockchain and dew computing-based architecture for a smart city model. The proposed model is a four-tier architecture containing physical nodes, dew, edge, and cloud. We have used the local blockchain application in the dew tier, whereas, in the cloud tier, we have used the global blockchain application. The proposed architecture reduces the latency ~ (25–30)% and power consumption ~ (35–41)% using two different blockchain applications. We have used Amazon Web Services (AWS) in our work while designing the global blockchain application. The CloudWatch monitoring tool has demonstrated the status of the global blockchain database. © 2021, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.
