Purpose: With the emergence of Online Purchasing, Product Identification is an essential model that allows the seller to add a product to a decentralized platform such as Blockchain and allows buyers to purchase the product from the decentralized platform. Fraud products, counterfeiting, and duplication are the current marketplace's major problems. This aims to develop a system for verifying product identification with their information, ownership, and validity detail. Design/Methodology/Approach: The proposed system applies Extreme Programming (XP) to reduce the risk caused by the fixed-time project using new technology and thus the final project could be delivered in time. Solidity and metamask being new technologies were unstable and to adopt the changes, the agile development model was the best through ABI and the bytecode are deployed into the Ethereum Blockchain. Findings/Result: This system maintains the buyers, sellers, and product details in a decentralized blockchain platform. This research details the entire product development process from planning, analysis, design, implementation, and testing for systematic online purchasing. Verifying the product ownership and its information to get the original product is the major difficulty in this space, but this research systematically solves some of those problems. This signifies an improvement in the current centralized way of purchasing goods online, where the information remains as it is entered by the seller while listing the product in Nepal and developing countries context. Originality/Value: The study has produced a decentralized, reliable, secure, and third-party independent marketplace for buying and selling products for fraud free market. Paper Type: Research paper

Purpose: The condition of the vehicle depends upon its maintenance. If there is a need of maintenance of a vehicle, then an optimum vehicle maintenance system is needed. This aims to develop a system for Vehicle Maintenance to facilitate the vehicle service through online access which is easy to use, simple, quick, and savvy. Design/Methodology/Approach: This venture is a basic web application for a vehicle fix/administration shop or business. It deals with the provision of user request through user’s information, location details, service details, etc. The main function of the system is to facilitate users through the best service with both pickup and drop off facilities. This task has a Public Module and Administrator Module using PHP Programming Language, Java Script, HTML, Bootstraps, and MySQL. Findings/Result: The administrator module is the side of the task where could the administration at any point deal with every one of the information recorded/can't avoid being recorded on the framework. Here, the administrator has full command over the framework including mechanics and administration expansion. Just the administrator can add information into the data set. The information can be recovered without any problem. The client can present their administration demand at this side and the submitted solicitation will be set apart as forthcoming. This undertaking can assist with decreasing the time consumed by the two closures (The board and Clients) as far as dealing with their administration demands. Originality/Value: An online system of maintenance with optimal time and minimized cost with the centralization data set has been developed to solve real-life problems. Paper Type: Research paper
