Description

Carbon Vault is a decentralized platform that bridges carbon analytics, verification, and trading through blockchain technology. It provides a transparent ecosystem where organizations, data providers, and validators collaborate to track, verify, and trade carbon value tokens (CVTs) with full trust and traceability.

Built on smart contracts and zero-knowledge proof mechanisms, Carbon Vault transforms traditional carbon tracking into a real-time, auditable, and data-driven system—ensuring environmental accountability without compromising privacy.


⚙️ Core Components

  1. Smart Contracts Layer

    • Automates issuance, staking, and trading of CVTs.

    • Handles validator rewards, emissions data submissions, and carbon yield distribution.

    • Ensures tamper-proof verification through immutable records.

  2. Data Analytics & Verification

    • Aggregates environmental data from IoT sensors, satellite feeds, and certified partners.

    • Uses validators to verify authenticity and generate cryptographic proofs.

    • Supports ZK-compliance checks for privacy-preserving validation.

  3. Carbon Marketplace

    • Enables companies to buy and sell CVTs backed by verified carbon reduction data.

    • Integrates a dynamic pricing model driven by supply-demand analytics and validator activity.

    • Promotes transparency by displaying source, proof, and yield of every trade.

  4. Staking & Yield Dashboard

    • Corporate buyers can stake CVTs for long-term sustainability commitments.

    • Validators earn rewards for accurate data validation and proof submission.

    • Real-time dashboard visualizes holdings, yield rates, and proof verification status.

  5. Wallet Integration

    • Seamless onboarding with MetaMask or Mantle SDK.

    • Users interact directly with smart contracts without centralized intermediaries.


💡 Vision

Carbon Vault aims to make carbon transparency accessible, verifiable, and economically rewarding.
By merging decentralized finance (DeFi) principles with climate analytics, it creates a sustainable bridge between environmental data integrity and financial incentive — empowering global climate accountability.
