Blockchain technology in the supply chain management classroom: Proof of Attendance Protocols

Abstract

This research demonstrates a method to introduce blockchain technology in the classroom based on the Proof of Attendance Protocol (POAP). A blockchain is a digital distributed ledger with the potential to improve transparency and trust between parties. Businesses are testing, piloting, and deploying blockchain technology across their organizations, and students show growing interest in the technology. This teaching brief proposes an exercise that uses POAPs, nonfungible tokens (NFTs) associated with an event, to help students understand blockchain technology within supply chain management contexts. Instructors can use the exercise for various purposes: as incentives for behavior the instructor wishes to encourage (such as attending class) or as prizes for games. The exercise also includes a glossary of blockchain-related terms to introduce the language of this industry to students. Student surveys showed a significant change in their knowledge of blockchain technology, specifically, a 41% increase in understanding of how blockchain technology may benefit supply chain management and a 35% improvement in the ability to explain blockchain technology to others. This brief concludes with resources to create and distribute POAPs for courses and other settings.
