ECOCERT
Technical Documentation Outline
v0.1
1. Abstract
- Real-time onchain attestation protocol for regenerative agriculture and carbon sequestration
- Combines IoT sensor streams, Chainlink oracle data, Groth16 ZK-SNARK validation, and ERC-721 soulbound token issuance on Base
- Achieves sub-cent gas cost, <60s end-to-end latency, and immutable public verification without trusted intermediaries
2. Problem Statement
- Current carbon inset and regenerative certification relies on centralized auditors, 6–12 month delays, and unverifiable paper/Excel processes
- Smallholder farmers (5–250 acres) cannot monetize verified practices due to high certification friction
3. Solution Overview
- Protocol: farmer-side web app captures geo-tagged IoT data → hashes → submits to Base smart contracts → atomic ZK verification → mints non-transferable ECOCERT soulbound token
4. Technical Architecture
4.1 Data Ingestion Layer
- Sensor integration: low-cost IoT probes
4.2 Oracle Layer
- Chainlink Functions: pulls NDVI satellite imagery, weather history, and price feeds
4.3 Verification Engine (Base Mainnet)
- Solidity v0.8.24 contracts:
- Immutable storage of hashed attestations
- Groth16 ZK-SNARK verifier for sequestration formula
- ERC-721 with EIP-5192 soulbound enforcement
4.4 Settlement & Escrow Layer
- Automated carbon credit
6. Security & Cryptographic Guarantees
- ZK-SNARK circuit: public inputs and private inputs
8. Roadmap
- 1: Base Sepolia MVP (next step)
- 2: Mainnet deployment + closed pilot expansion
- 3: Public farmer dashboard + corporate buyer portal
- 4: Governance token launch
The verifiable future of regenerative agriculture.
