| dc.description.abstract | Blockchain is one of the top ten technology trends in 2019, which provides a new state of trust model mechanism. As Taiwan has been in food safety storm in a long time, there are still many functional limitations of today’s social food traceability system. Especially for the organic food traceability, unknown food sources and opaque supply chain processes are still the problems. Hence, this study aims to develop a blockchain network based on Hyperledger framework and use the contextual simulation method to simulate the organic food traceability process. Hyperledger Fabric and Hyperledger Composer are used to create the relevant features of the blockchain. The situational simulation content is built into the erected blockchain network. The key features include decentralization, openness, independence, security, and anonymity, which enable the erected blockchain network to meet these characteristics. In the blockchain system, the relevant participants, roles and their assets are established, the operational rights related to the participants and roles are defined. Consumers can query the organic authentication related information of the food through the REST API interface.
The research found that using blockchain network to build an organic food supply chain can make its internal organic food content and raw material supply process open and transparent, because organic foods will be accompanied by relevant organic food certification certificates, which cannot be improperly manipulated by interested parties. Operating a smart contract on a blockchain network will save a lot of time and cost, simplify the workflow, and automatically run the organic food-related asset creation login on the blockchain network. | en_US |
