Mujeeb-ur-Rehman et al., International Journal of Emerging Trends in Engineering Research, 9(7), July 2021, 967 – 972 967 ABSTRACT The days, the usage of E-commerce applications in the distributed network has been increasing progressively. These applications bring many advantages such as online shopping from different places. For the sake of simplicity, offloading data of applications from user devices to servers lead to many research challenges. This paper devises a novel blockchain-enabled system for E-commerce applications. The network consists of ethereum nodes that can implement symmetric security to provide valid and secure hashing of data in distributed computing. The simulation results show that the proposed blockchain-enabled system outperforms all existing systems in terms of security Key words: Blockchain, Data, System, Offloading, Application 1. INTRODUCTION 1.1 E-commerce The E-commerce has highlighted factors for its popularity like high goods and products, smart transactions and much more relatable services where some of fields [1] are needed to discuss to cater any request like, generated ID’s, location and even phone numbers which may tends towards privacy issue specially for comments section under any product. Here it can be a challenging to threaten any customer for their delivered reviews against products. To control such activities [12] we have different technologies and blockchain is one of them to ensure privacy of customers for their product reviews and e-payment details. 1.2 Blockchain technology It is distributed inflexible ledger which supports system for keeping records, transactions and tracking resources in network where each node is connected with each other and every node is called as a block. Blockchain is an ideal for information as it supports [15] frequent, distributed and clear delivery of information stored on inflexible ledger which is only available by permissioned network members. As name reflects [8][12][16] Blockchain is consisting on blocks (“digital pieces of information”) and chain (“stored in a public database”) with involvement of cryptography every block is linked with each other for data security, entered data cannot be amend in block. 1.3 Cryptography A method of storing and transmitting data in a specific way where only reliant can read and process. Cryptography is associated with the way toward altering over familiar plain content into invisible content and the other way around. It is a [17] technique for putting away and meet up information in a particular structure so just those for whom it is expected can examine and handle it. Cryptography shields information from stealing or modification, yet can likewise be utilized for client verification. In cryptography, we start with the decoded information, mention to as plaintext. Plaintext is scrambled into figure text, which will thusly (for the most part) be decoded once again into usable plaintext. The encryption and decoding influenced by on the sort of cryptography work together being utilized and some type of key. 1.4 Cryptocurrency A digital payment system built using Blockchain technology where transactions occur without involving banks as anyone can send and receive money digitally other than carrying physically. This transaction takes place in a public ledger and entries are carried on an online database. 1.5 Current Payment Systems Any electronic devices like, computer, phone, printer and many other are connected through internet are nodes, to ensure the security of blockchain in different fields we have focused on banking sector where offered services like bill payment, fund transfer, account information (personal details) is frequently accessed which needs to be secured, the main idea to state this problem is security, here each of the transaction will be stored in blocks without involvement of third parties. In addition to discuss contemporary payment systems, it is basically to reduce banking procedures and to facilitate community with ease and Cyber Security Intelligence and Ethereum Blockchain Technology for E-commerce Mujeeb-ur-Rehman 1 , Abdullah Lakhan 2 , Zahoor Hussain 3 , Fida Hussain Khoso 4 , Aijaz Ahmed Arain 5 1,2 Benazir Bhutto Shaheed University Lyari Karachi, Sindh, Pakistan, mujeebshaikh137@gmail.com, abdullahrazalakhan@gmail.com 3 Computing Department FCIT, Indus University Karachi Pakistan, Email:zahoor.shah@indus.edu.pk 4 Dept. of Basic Science, Dawood University of Engineering & Technology Karachi, Sindh, Pakistan, fidahussain.khoso@duet.edu.pk 5 Deptt.of Computer Science, Quaid-e-Awam University of Engineering, Science &Technology Nawabshah, Pakistan, aijaz@quest.edu.pk ISSN 2347 - 3983 Volume 9.
