BLOCKCHAIN EMPOWERED E-COUPON SERVICE

Abstract

As the realm of e-commerce continues to burgeon, electronic coupons (e-coupons)
have become indispensable for their convenience and portability. However, prevalent
e-coupon services, which centralize information on dedicated servers, often grapple
with security vulnerabilities. Centralization exposes e-coupon systems to risks such as
information forgery and the reuse of expired e-coupons, leading to challenges in
verifying users and owners. To fortify the security of e-coupon services, this study
advocates a paradigm shift by harnessing the capabilities of blockchain technology.
The proposed e-coupon service adopts a blockchain system to instill robust security
measures. The strategy involves the design of a dedicated server that orchestrates the
e-coupon service and seamlessly interacts with the blockchain system. A crucial
component of this approach is the formulation of a smart contract within the
blockchain system. This smart contract not only ensures the integrity of the e-coupon
business logic but also safeguards the information associated with each e-coupon. The
choice of Ethereum as the underlying blockchain system for implementation
showcases the practicality and feasibility of the proposed service.
In practical terms, the experimental implementation of our solution on the Ethereumbased
blockchain system yields promising results. The comprehensive testing and
evaluation reveal that the proposed e-coupon service significantly enhances security
without imposing substantial performance overhead. This marks a pivotal advancement compared to existing e-coupon services, affirming the viability of integrating blockchain into e-coupon systems as an effective security enhancement.
