CarChain

Repository

CarChain is a cutting-edge decentralized application (d-app) designed to address the challenges and risks associated with second-hand car sales. This platform uses the power of blockchain technology to establish trust, transparency, and accountability in every car transaction. By creating a secure and efficient environment, CarChain aims to enhance the car buying and selling experience for both buyers and sellers.

Key Features of CarChain

  1. Smart Contract Creation: Car owners, including private individuals and auto dealers, can create unique smart contracts for the cars they intend to sell. These smart contracts capture crucial details such as the license plate, chassis number, brand, type, and color of the car.

  2. Visual Verification via IPFS: CarChain allows sellers to upload pictures of the car securely on the InterPlanetary File System (IPFS). This ensures that potential buyers can visually verify the car's condition, promoting transparency and avoiding misrepresentation.

  3. Mileage Integrity Assurance: To combat odometer fraud, CarChain allows you to track and update car mileage. During APK inspections or services, auto dealers can securely update the car's mileage, guaranteeing that the recorded data is accurate and higher than the previous reading.

  4. Secure Selling Process: Only the current owner possesses the authority to list the car for sale and set an asking price. Upon the buyer's payment and successful car delivery, the smart contract automatically transfers the payment to the seller. Simultaneously, the blockchain updates the car's ownership, streamlining the selling process.

Technology Stack

CarChain's functionality is made possible through the following technology stack, including:

  1. Next.js: This powerful framework enables the creation of a user-friendly and efficient front-end interface. Users can easily navigate and interact with the d-app, enhancing the overall user experience.

  2. web3: The integration of web3 ensures smooth and seamless interaction with the underlying blockchain. This allows CarChain to access and utilize smart contracts efficiently.

  3. Solidity: As the language of smart contracts, Solidity is at the core of CarChain. It allows for the creation of unique non-fungible tokens (NFTs) for each car, ensuring secure ownership and tamper-proof car history.
