DIMO ensures vehicle data authenticity through blockchain technology and robust verification mechanisms. Each vehicle is assigned a unique digital identity via an NFT, creating an immutable record on the Polygon blockchain. Data from sensors and ECUs, collected through OBD-II devices like AutoPi, is encrypted and logged on-chain, preventing tampering. Smart contracts automate data access and transactions, ensuring transparency and traceability. All data transactions are publicly recorded, providing a verifiable audit trail. By integrating with IoTeX’s W3bstream, DIMO enhances data integrity for Web3 developers. Vehicle owners control data sharing, with authenticity guaranteed by cryptographic signatures and decentralized storage, fostering trust in the ecosystem.
