Decentralize transaction records of digital payment gateway using Ethereum Blockchain and Interplanetary File System

This research proposes a system to store transaction records from a payment gateway based on digital payments by utilizing blockchain technology and Interplanetary File System (IPFS) as distributed storage. In digital payments, the possibility of online fraud or theft of customer data is a problem that needs to be solved. Although the solution is to use a Payment Gateway with security standards to prevent these problems, the system is still centralized and vulnerable to the possibility of system failure or data changes by irresponsible people. Blockchain furnishes a secure and unalterable record for documenting payment transactions. Conversely, IPFS presents a decentralized and immune-to-censorship approach for storing and accessing data. The usage of these technologies guarantees the secure storage of payment transaction data and related documents (such as invoices and receipts) while effectively thwarting data manipulation or censorship attempts. Therefore, this research aims to build a blockchain technology system to increase security and maintain the integrity of the data generated from the Payment Gateway. This research using distributed data storage using IPFS to save transaction from the payment gateway data. Based on the evaluation and security analysis results, implementing a blockchain technology system to store transaction records from digital-based payment gateways can improve data security and integrity. In the gas fee increase analysis, the gas fee will increase according to the total number of bytes generated when the transaction is made, where each byte will cost 12 gwei to pay the gas fee.

IOT Based Wastewater Management in Smart Cities

The process of extracting and refining contaminants from drainage or wastewater so they can be recycled back into the water supply with the least amount of negative environmental impact is known as wastewater management. The current declining environmental condition necessitates the development of new strategies and tactics to guarantee safe and intelligent wastewater management systems in smart cities. The Internet of Things (IoT) and wireless sensor networks are potential technologies for treating wastewater. The comprehensive literature review develops a conceptual framework utilizing blockchain technology for an Internet of Things (IoT)- based wastewater management system in smart cities (IoT- WMS). Information is now being stored using blockchain technology to create an incentive scheme that promotes the reuse of waste water. In smart cities, tokens related to the quantity and quality of recovered wastewater are distributed to homes and businesses. However, this frequently promotes manipulating the data used to award these tokens in order to incorporate particular benefits. To determine whether there is evidence of altered IoT sensor data, anomaly detector techniques are employed. In order to facilitate the most efficient distribution of water depending on user usage at the plot holding level, this study suggests a water distribution and integrated management system based on the Internet of Things (IoT) and data analytics (DA). In addition to preventing water waste, the suggested approach would assist in gathering consumption statistics for macro-level research and town planning
