Analysis and design of transparent smart contract based on blockchain technology for supply chain in “Gasol flour” industry

The current contract system that has been running in a supply chain is not necessarily going well. Particularly, this contract was attributed by unfairness distribution of margins in each stakeholder, which causes one of the stakeholders took place as disadvantaged ones. This challenges potentially overcame by industry 4.0 paradigm constructing a smart contract system based on blockchain technology. This study aims to analyze the task of each stakeholder to achieve a transparent smart contract system and design system for a transparent smart contract that is able to provide a fair and transparent contract for each stakeholder involved in the supply chain of "Gasol flour" industry. By the existence of a smart contract, each stakeholder visibly and determine what contracts to establish and to create with other parties a transparently. The relief method used in this research provides input in the form of features needed to make a contract system in the supply chain of "Gasol flour" industry. Furthermore, these features are selected to obtain an output in the form of contract items to display in the distributed smart contract system. The selected items are input to run IF-THEN logic on the smart contract system using the M5P Tree algorithm method. The main results of this study are to obtain features that have the most influence on a transparent smart contract system and the rule of the selected feature so that a system is able to provide a fair contract for each stakeholder established in the supply chain of "Gasol flour" industry.
