A Prototype Design for Gamified Blood Donation App Using Blockchain Technology, IPFS and NFTs

Abstract

Donating blood is a common practice that has a positive effect on the lives of several individuals. Daily, the number of people in urgent need of blood continues to rise substantially. It is often challenging to find a suitable donor in case of emergency. The situation is worse if it is a rare blood group. This paper introduces a blockchain-based decentralised application (DApp) to match recipients with blood donors during an emergency. Personal information such as name, location, blood group, and donation history is stored securely in the blockchain distributed ledger through IPFS. The donors' lack of awareness and motivation are the primary reasons for people not coming forward for blood donations. We propose to gamify the blood donation process by issuing NFT badges as a reward for donors. This paper explains the design of smart contracts for storing donor and recipient data on the ledger and issuing NFTs to donors. The article also briefly discusses the process of designing the DApp.
