Supply Chain Traceability For Energy Resources Using Blockchain

Abstract

The purpose of the Energy Supply Chain smart contract that is being given here is to enable an Ethereum blockchain-based transparent and safe supply chain management system for energy items. The contract uses a decentralized method to track the lifespan of energy goods from producer generation to consumer use. It was implemented in Solidity version 0.8.0. According to the contract, the products can be in one of the following states: “Created,” “Shipped,” “Received,” “In Use,” and “Completed.” To guarantee that certain tasks can only be carried out by approved parties, including the contract owner, product manufacturer, distributor, and customer, the agreement makes use of a series of modifiers. The contract permits the production, shipment, receipt, use, and completion of energy products through a sequence of actions and state transitions. The contract owner's production of energy products, the producer's delivery of goods to a distributor, and the confirmation of receipts are among the essential features. by the distributor, the customer starting to use the product, and the product's lifecycle coming to an end. By setting off these events, the product's route through the supply chain is transparently documented. Through the utilization of smart contracts and blockchain technology, the Energy Supply Chain contract improves transparency and confidence in the energy supply chain. It provides a decentralized approach to tracking and certify the origin of energy goods from production to consumption.
