EcoChain replaces months manual carbon credit audits with real-time IoT verification, enabling Nigerian businesses to mint, trade, and retire verified carbon credits in minutes. It solves the Africa Discount by providing blockchain-backed transparency that international buyers trust. # EcoLedger NG > **Nigeria's First Decentralized Carbon Credit Exchange** --- ## 1️⃣ What Problem Are We Solving? Nigeria loses **billions in climate finance** every year due to slow, expensive, and opaque carbon credit verification processes. Traditional carbon credit audits take **12–18 months** and cost thousands of dollars in consultant fees — putting the system out of reach for most Nigerian businesses and farmers. Furthermore, **double-counting** (selling the same credit twice) is rampant in manual registries, undermining the integrity of the entire carbon market. --- ## 2️⃣ Why Is It Important? - Nigeria is committed to reducing emissions by **47% by 2030** (NDC targets). - The voluntary carbon market is expected to reach **$50 billion by 2030**. - SMEs, solar farms, and gas flare operators in Nigeria generate **real, verifiable carbon reductions** but lack access to the global market. - Transparent, on-chain records eliminate fraud, empower local projects, and attract international climate capital. --- ## 3️⃣ How Does It Work? EcoLedger NG is a **dMRV (decentralized Measurement, Reporting & Verification)** engine that: 1. **Measures** carbon reductions using real-time IoT sensor data (solar output, gas flares, biogas, etc.) 2. **Reports** via a signed oracle that pushes verified readings on-chain 3. **Verifies** automatically using smart contracts — no auditor required 4. **Issues** ERC-3643 compliance tokens directly to the emitter's wallet 5. **Trades** credits on the marketplace — buyers pay in Naira via Interswitch; settlement is on Base Sepolia ### System Flow ``` Hardware Sensors (ESP32 + Secure Element) │ Cryptographically-signed readings (ECDSA) ▼ Oracle API (/api/oracle) — validates signature, stores in DB │ ▼ (if CO₂ reduction ≥ 1,000 kg) MRVOracle.sol → EcoCredit.sol → Mint ERC-3643 Token │ Buyer (MTN, Dangote…) → Interswitch IPG (Naira) │ On-Chain Settlement → National Registry ``` --- ## Project Description **EcoLedger NG* …
