The Development Off-Chain Blockchain Smart Contract Model on MSCWR SmartBox

A smart contract is a business process agreed upon to run. With a smart contract, all business processes can run automatically after the smart contract receives a trigger and cannot be canceled or changed. Previous research on smart boxes is generally only used for health storage of smart drugs. In this study, facilitated off-chain blockchain model MSCWR SmartBox will focus on shipping for logistics, such as for the use of shipping goods such as valuables. This research focuses on creating an off-chain blockchain smart contract model that is written in pseudocode to support the operations of the MSCWR SmartBox. The creation of off-chain blockchain smart contracts is very important in supporting the MSCWR business process. Making off-chain blockchain Smart Contracts is very important considering the business processes that create follow the Multichain process (Blockchain applications for cryptocurrencies without changing the multichain application). The research method used is user-centered design (UCD). In this study, we use an application prototype approach, use multichain as a blockchain platform and use the environment at BeeBlock Laboratories. The validation and testing of the equipment used with proof of logs from the server show that the smart contract created can be used to support the business processes of the MSCWR SmartBox.
