Architecture Overview
DecentrAgri combines IoT, blockchain, and decentralized storage to create a robust pipeline for collecting and distributing agricultural data. Our architecture ensures that every dataset—from farm to dashboard—is secure, traceable, and tamper-proof.
🌡 Sensor Network
DecentrAgri deploys smart environmental sensors across partner farms to capture high-resolution agricultural data in real time. These multi-functional probes monitor:
🌱 Soil Moisture
🧪 Soil pH Levels
☀️ Sunlight Exposure
🌡 Temperature & Humidity
🌧 Rainfall (where applicable)
🌾 Crop-Specific Growth Indicators
Sensors are solar-powered, connected via WAN/Wi-Fi/5G, and calibrated for different crop types and terrains.
Edge Processing & Secure Transmission
Each sensor unit features an onboard processor that:
Performs preprocessing and anomaly detection on raw data
Encrypts data using AES standards
Transmits datasets to the core server via secure protocols (HTTPS/SSL)
This ensures data integrity from the point of capture to backend ingestion.
📍 Decentralized Storage via IPFS & Metadata NFTs
Once verified, incoming datasets are:
Structured into standardized formats (e.g., JSON, CSV)
Pinned to the InterPlanetary File System (IPFS) for decentralized and permanent storage
Linked to metadata and minted as non-transferable NFTs on a blockchain such as Polygon, Ethereum, or ApeChain
Each NFT includes:
📍 GPS Coordinates
📅 Timestamp
🌽 Crop Type
🧪 Sensor ID
✅ Farmer Consent Indicator
⚠️ These NFTs are not designed for speculation or trading — they are metadata containers for auditability and provenance.
🌍 Explorer Dashboard
A public-facing dashboard allows users to visualize and interact with on-chain farm data:
🔍 Filter by region, crop type, or date range
🌍 View data entries mapped to farm locations
📊 Download open datasets for offline research
🧠 Access enriched insights for decision-making
