Abstract: Blockchain has become an increasingly prevalent subject in the last decade, with potential uses in supply chain, healthcare, and finance, among other areas. In academics and industry, its immutability, transparency, security, and decentralization attracted much attention. The Internet of Things is one technology that blockchain can assist (IoT). Yet, issues with blockchain's scalability, performance, and complexity continue to pose obstacles to its practical use. With specific focus on Internet of Things applications, this study adds to a comparative analysis that evaluates the performance and scalability of blockchain platforms. We focus on Ethereum, Hyperledger Fabric, and IOTA blockchain platforms. An IoT healthcare use case is created as part of the deployment. To determine the throughput and latency criteria, we tested the scalability and performance of private platform networks. We looked at how the platforms under study behaved when the number and rate of transactions increased to assess scalability. Hyperledger Caliper is used to collect these parameters. Experiment analysi s shows that Hyperledger Fabric performs better than Ethereum and IOTA in terms of transaction throughput and latency, making it highly suitable for enterprise applications that require high performance and scalability within a permissioned network. Regarding performance and scalability, Fabric was more ideal than IOTA, followed by Ethereum for private networks such as IoT healthcare ecosystems.
