Deploying and Assessing the Efficiency of Ethereum Blockchain for Ensuring the Security of Web of Things

The characteristics of blockchain technology, which is a decentralised database or "distributed ledger," include independence, lack of central authority, and a trustless setting. Because of these characteristics, blockchain technology is well-suited for use in many IoT applications. This article details a real-world use of the Proof of Authority (PoA) Ethereum blockchain on an web of Things (IoT) system. In order to study and highlight potential challenges that might impact the integration of blockchain with IoT, and to set the stage for future research and potential solutions to these concerns, this implementation was carried out in a practical sense.
