Abstract The long cocoa supply chain in Indonesia makes cocoa difficult to trace, data in several countries in Indonesia related to national cocoa data. National cocoa production data is needed in creating policies that are right on target, so these things need to be done. The development of industry 4.0 makes the creation of blockchain technology that can overcome these problems. To create a blockchain system for the cocoa supply chain needs a requirement analysis for the time of making the application. The purpose of this research is to identify the needs and know the interactions that occur in the blockchain chain system in the cocoa supply chain. The method used is requirement analysis, use case diagram, and sequence diagram. The results of this study are two inputs: the structure of the cocoa supply chain and activities that occur in the cocoa supply chain, four stakeholders: farmers, collectors, agroindustry, and exporters, one output: the blockchain system from the cocoa supply chain. Interactions that occur in the system is log in to the system, add the activity, execution phase, ordering phase, and validation phase.
