However, the security of smart homes has become a major concern due to their vulnerability to information theft, activity monitoring, data tampering, and information attacks. In this study, the author proposes a blockchain-based security system for smart homes using the Proof of Authority (PoA) consensus algorithm, which only allows trusted and reputable users to access information on the web3 platform. Web3 is built using various programming languages, including JavaScript, Solidity for smart contracts, Python for data processing, and HTML, CSS, and React.js for website development, with transactions carried out by users using Metamask. To test data accuracy, the author validated the value against 100 transactions. To test the security of the system, the author simulated attacks that attempted to monitor and modify information using tools like Burp Suite, as well as exploits that leveraged the client site path to process information using XSpear. The results of this study demonstrate that the proposed system can monitor activities in the home and prevent unauthorized information access, allowing only trusted and reputable users to access the system.} }
