Truth & Seal: Cryptographic Integrity
Librae secures the boundary between the physical and digital world. We combine localized ground sensors with immutable cryptographic ledger entries to prove ecological reality.
Physical Ground-Truth
Remote sensing alone cannot verify ecological truth. CAHAYA coordinates with physical **Sentient Master Nodes** deployed on-site.
These master nodes ingest local telemetry from a **LoRa Mesh Network** of low-power worker sensors placed across the concession. Running local, air-gapped YOLOv8 computer vision models, the nodes verify ground parameters (like canopy cover, tree diameter, and water clarity) in real-time.
Local Autonomy: The entire ground sensor mesh functions without internet access, storing telemetry in encrypted local databases until authenticated sync handshakes are executed.
Local Sensor Mesh Network
Sentient Master Node
Central coordinator. Runs YOLOv8 and encrypts telemetry payload.
LoRa Mesh Array
P2P mesh routing data across 15km concession without telecom grids.
Worker Nodes
Solar-powered canopy, acoustic, and water quality sensors.
Local SQLite DB
Secures local logs on physical nodes until authorized sync.
The Integrity Protocol
Concession bounds and point-clouds are loaded locally into the CAHAYA workspace node.
The system computes a unique SHA-256 hash receipt for the dataset, locking its initial state.
Individual file hashes are structured into a Merkle tree, generating a single cryptographic Merkle Root.
The Merkle Root is written to the Polygon L2 ledger, anchoring the physical asset state forever.
The Cryptographic Seal
Once ground parameters and boundary polygons are verified, the system generates an immutable cryptographic seal. By grouping files into a Merkle tree structure, we write only the root hash to the Polygon L2 blockchain ledger.
This creates a permanent anchor. Anyone with the original files can verify their integrity against the blockchain hash. If even a single polygon vertex or sensor log is altered, the Merkle root changes, failing verification instantly.
The 30g Carbon Pledge
Unlike traditional blockchain mining, Librae writes hashes to Layer-2 rollups in batches. We generate less than **30 grams of CO₂** per verification run, making our proof framework net-positive for the environment.
