D-Donation: Charity Fraud Prevention using Blockchain

Abstract

Abstract: Charity is an act of kindness, wherein a person who has financially more than enough of what he needs contributes part of his surplus earnings for the fulfillment of the needs of folks who are much less capable. The charity organizations lack transparency and the supervision of them is difficult to achieve, which has a negative impact on the willingness of the people to donate. Blockchain as an underlying technology provides a new solution for the charity system in terms of technology. This project proposed a charity system (D-Donation) based on blockchain technology and expounds the design pattern, architecture and operational process of the platform. Some core functions of the D-Donation app have been realized and verified on Polygon Blockchain. Through this we hope to increase the transparency of charities to enhance the public's trust in charities and promote the development of philanthropy by blockchain-based charity system.
