Abstract
Ethiopia is one of coffee producing countries in the world, especially it is known for coffee Arabica. The coffee supply chain includes different participating organizations from its production place up to its consumption in the international market. Ethiopian coffee suffers from the two most prominent supply chain problems which are provenance traceability and transaction transparency for the participating parties. In this paper, we tried to implement blockchain technology for the Ethiopian green coffee supply chain to improve traceability and transparency by using Sidama coffee as case study. Distributed ledger technology was proposed to solve those problems by distributing a record of coffee transactions throughout the network participants. Among available blockchain technologies, we choose Hyperledger blockchain technology because it is suitable for business to business (B2B) model. We were able to design and implement a number of smart contracts using Hyperledger composer modeling language based on our field study and deploy them in the underlying Hyperledger Fabric blockchain network. The prototype system was able to create a traceable route for the coffee by recording every transaction in an immutable and untampered way and the transactions were transparent for participating parties since they get an exact copy of ordered transaction as a block. We also were able to solve confidentiality issues in the network by implementing multiple channels in the network.
