Toward an integration of blockchain technology in the food supply chain
通过实验和定性证据，研究了消费者为何看重区块链提供的可追溯性，以及供应商在采用区块链时面临的障碍，发现本地食品中区块链能增强消费者信任，但供应商因内部支持和数据共享顾虑而犹豫。
The traceability of what we eat is a lingering issue. Blockchain enables transparency across the value chain as it tracks a product’s origin, location, and history. In this work we adopt a mix-method approach - experiment plus qualitative evidence - to understand why consumers consider the traceability offered by blockchain important and what are the barriers that suppliers face when considering blockchain adoption. Our findings show that, when the food is local, blockchain increases consumers’ trust and, in turn, attitudes and behaviors toward the sharing experience. On the supply side, we find that, while operators see key benefits in blockchain adoption – including enhanced trust, they are still hesitant in using the technology because of a greater need for intra-organizational support and a concern in data sharing. By looking at both consumers and suppliers, we offer a complete picture on the integration of blockchain technology in the food supply chain.
