Revolutionize the auto industry with AutoBloc, a cutting-edge DApp! ๐โจ Ensure transparency and security using smart contracts and cryptographic functions, creating a seamless, trustworthy journey from manufacturing to online purchases. ๐๐๐ #AutoBlocRevolution #SmartSupplyChain #BlockchainInAutomotiv
This project focuses on implementing a robust and secure supply chain management system using blockchain technology.
Smart contracts are employed to track the lifecycle of a product from manufacturing to customer delivery.
The core security is established through the use of the keccak256() function, generating secure 256-bit hashes at each stage of the supply chain.
๐ญ Manufacturing Stage:
The product lifecycle begins with the manufactureProduct() function, initializing the product and storing manufacturer details in the blockchain.
productHistory[] is initialized, and the current product data is linked to the manufacturer as the owner.
๐ Third Party Purchase:
Upon purchase by a third-party seller, the purchasedByThirdParty() function is triggered.
Owner is set to the third party, and the current product data is added to the productHistory[].
Simultaneously, the product is shipped by the manufacturer (shipToThirdParty()), and details of the third-party seller are recorded (receivedByThirdParty()).
๐๏ธ Online Customer Purchase:
Online customer purchase involves a series of checkpoints:
Third Party ships the product (shipByThirdParty()).
Product is received by the delivery hub (receivedByDeliveryHub()).
Owner is set to the delivery hub, customer details are stored, and the current state is added to productHistory[].
Delivery hub ships the product (shipByDeliveryHub()).
Product is received by the customer (receivedByCustomer()), and the final state is recorded in productHistory[].
๐ Verification and Security:
All juncture functions are executed only after complete verification of the product and productHistory[].
Customer confirmation and acceptance are crucial before updating the state by clicking the receive button.
๐ Data Retrieval Functions:
Various functions (fetchProductPart1(), fetchProductPart2(), etc.) are provided to retrieve specific data about a product based on its UID and data type (current state or history).
The use of Solidity cryptographic function keccak256() ensures the integrity and security of certificates generated at each shipping stage.
๐ Immutable Smart Contracts:
Smart contracts in the mainnet are immutable, contributing to the overall security of the supply chain setup.
๐ Data Integrity and Origin Tracking:
productHistory[] serves as a comprehensive record, allowing stakeholders to track the origin and handling of the product at every stage.
๐ก๏ธ Mainnet Security:
The mainnet security relies on the immutability of smart contracts and the secure 256-bit hashes generated by keccak256().
Certificates generated at each shipping stage provide an additional layer of security in the supply chain.
๐ Conclusion:
This blockchain supply chain management project ensures transparency, security, and traceability throughout the product lifecycle, offering a reliable solution for businesses and consumers alike
