The internet of things is a powerful combination of wireless devices, radio-frequency identification, and numerous sensors that offer the challenging but powerful potential of shaping current systems to make them smarter. IoT has many different areas of application and one such area is healthcare. The health sector is another promising area for IoT, and several businesses are exploring its application in this sector. In this study, it is proposed to collect healthcare data through the IoT and store it in the Interplanetary File System using Ethereum-based blockchain technology for data security. Blockchain technology is used in IoT to ensure the safety of collected data. Blockchain technology is used in IoT to ensure the safety of collected data. Smart contracts are used to automatically execute, control, and record events following the terms contained in them, enhancing the characteristics already present in the blockchain. IoT-based healthcare solutions are tested on many blockchain networks.
Top1. Introduction
The term “Internet of Things” is used to describe a network of linked objects that may exchange data and other information through the Internet. Things in the IoT are high-tech gadgets that have sensors, apps, and other electronics have been analyzed by Garg et al. (2021). Though limited in power, these gadgets can detect their surroundings and respond accordingly. Because of the IoT’s superior automation, optimization, and analytical capabilities, it has had a profound influence on virtually every sector (Rani & Chauhan et al., 2021).
The usage of sensors or other components included in smart devices has made data collection, administration, and processing easier in the modern world. Wearables, smartphones, smart automobiles, and many more are just some of the smart gadgets that can connect to the internet and form a network that allows them to share and receive information. Inventory management, smart farming, retail, smart cities, smart healthcare, security systems, and so on all benefit from this form of network connection has been analyzed by various researchers such as Haleem et al. (2021), Abu-Elezz et al.(2021), Patela et al. (2023), Ettiyan et al. (2023) and Das et al. (2022) .
The healthcare sector has also undergone revolutionary change as a direct result of the rapid growth of IoT. Users may have trouble finding enough storage space for the massive volume of data generated by the proliferation of IoT-connected gadgets as discussed by Yadav et al. (2023). As a result, numerous businesses and academic organizations frequently use the method of storing data in a cloud environment. The level of safety offered to data kept in the cloud, however, is largely dependent on the security strategy used by the cloud service provider as suggested by Thirumalai et al. (2020).

Data exchange in an IOT environment
Since the user has no control over the cloud data storage, the data may be in danger from the presence of a large number of hackers and malicious users. To link IoT devices to the digital world, a communication network is necessary. This is true regardless of the environment, whether it be a cloud or another sort. Maintaining a high level of security is therefore important to guarantee that the sensitive data of users will not be compromised by any adversaries. Various novel techniques have been designed and implemented by the various researchers such as Singh et al. (2023), Yadav et al. (2022), and Singh et al. (2023) for the reliability of IoT.
