Project Brief

Overview

DeVahan is a decentralized automotive ownership and intelligence platform built to solve the persistent challenges in vehicle registration, service record management, and ownership transparency. By leveraging 0G Chain, 0G Storage, Data Availability, and 0G Compute, DeVahan transforms every vehicle into a verifiable, intelligent digital asset.

Problem Statement

Traditional vehicle management systems face multiple issues:

  • Illegitimate registrations and fraudulent documentation

  • Slow, paper-heavy ownership transfers taking weeks

  • No unified digital registry for accessing vehicle history

  • Multiple intermediaries, enabling corruption and inflated costs

  • Tampering of service records, mileage, and odometers

  • Manual and inefficient verification processes for vehicle history

These gaps make buying, selling, and owning vehicles risky and opaque.

Solution

DeVahan introduces a decentralized vehicle identity system where each vehicle is represented as a dynamic NFT with verifiable ownership history, service logs, inspection records, and real-time intelligence.

Key capabilities include:

  • On-chain registration, ownership management, and service updates

  • AI-powered vehicle assistant for real-time Q/A

  • Tamper-proof service and repair logs stored via 0G Storage

  • Trust Score & predictive maintenance through 0G Compute

  • Secure marketplace for verified vehicle transfer

Key Features

  • Vehicle AI Agent: Each vehicle has a personalized AI assistant powered by 0G Compute.

  • Dynamic NFTs (iNFTs): Vehicles become evolving NFTs that record service data, repairs, transfers, and more.

  • On-Chain Intelligence: Smart contracts calculate Trust Scores, detect anomalies, and issue insights.

  • Upgradable NFT Logic: Upgrade vehicle “brain” logic without reminting NFTs.

  • Verifiable Ledger: All vehicle metadata links to immutable records on 0G Storage.

  • Role-Based Access: Dealers mint NFTs, service centers upload service records, and owners manage assets.

  • Trusted Marketplace: Secure on-chain transactions for buying and selling vehicles.

  • User-Friendly UI: Simple dashboard with chatbot guidance.

Target Users & Market

  • Vehicle owners (cars, bikes, EVs)

  • Dealers & showrooms

  • Service centers & authorized workshops

  • Used vehicle buyers & sellers

  • Insurance companies

  • Automobile OEMs seeking analytics

The global used vehicle market is massive and plagued by fraud; DeVahan addresses the trust deficit directly.

What Makes DeVahan Unique

  • True on-chain vehicle identity (iNFT-based)

  • End-to-end lifecycle management (ownership → service → resale)

  • AI-driven predictive maintenance and insights

  • Fully tamper-proof records validated via 0G Storage & DA

  • Marketplace with verified assets and trust scoring

  • Upgradable NFT logic—no reminting required

  • Ability to query a vehicle’s entire history through an AI agent


How Will You Integrate 0G?

Planned 0G Integration

DeVahan seamlessly integrates 0G across three main layers:

:white_check_mark: 1. 0G Storage

Used for storing raw service records, maintenance details, mileage logs, inspection reports, and repair documentation.

Technical Implementation:

  • Service centers upload JSON/PDF records

  • Files are stored on 0G Storage

  • NFT metadata stores pointers to raw files

  • Data Availability ensures tamper-proof history

:white_check_mark: 2. 0G Compute

Used to create a Vehicle AI Agent and run predictive analytics.

Features using 0G Compute:

  • Customized AI assistant per vehicle

  • Real-time Q/A about service history, accidents, repairs

  • Trust Score calculation

  • Predictive maintenance estimation

  • Future: On-chain machine learning updates

:white_check_mark: 3. 0G Chain

Smart contracts deployed on 0G Mainnet include:

  • Vehicle passport/iNFT logic

  • Ownership transfer contracts

  • Role-based permissions (dealer, service center, owner)

  • Marketplace contract
