Sensor reads. Ed25519 signs. DAG chains. Merkle proves. Any third party verifies. From raw soil-moisture reading to court-admissible audit log, every byte of agricultural sensor data flowing through AgWaterAI is cryptographically attested and externally auditable.
Every sensor reading is signed at ingest with Ed25519, hashed into a DAG node, and chained to prior nodes. Each per-site attestation produces a Merkle root that proves the entire reading history without exporting the raw stream. Court-admissible by construction.
The attestation package contains the Merkle root, the signed DAG slice, auditor co-signatures, and a verification trail. Any consumer with the public key can verify integrity offline. No trust in AgWaterAI required.
Static water-rights datasets cannot underwrite a parametric trigger, qualify a hyperscaler water credit, or satisfy a SGMA auditor. Cryptographically-attested in-situ measurement can. DAG-TAT is the only piece of agricultural infrastructure that produces this artifact.
Each multi-depth sensor reading is signed at ingest with a per-site Ed25519 private key. The signature binds reading-value, sensor-id, depth, and ingest-timestamp into a single tamper-evident record.
The signed reading becomes a node in a directed acyclic graph. Each node references one or more prior nodes by hash, forming a tamper-evident lineage. Unlike linear chains, DAG topology allows parallel writes from many sensors without serialization bottlenecks.
Per-site attestations compute a Merkle root over their reading set. Partial verification is possible: a consumer can verify any single reading is in the attested set without receiving the full dataset.
A SGMA-certified auditor co-signs qualifying attestations. The co-signature is part of the chain and is independently verifiable by any third party. This makes the attestation court-admissible and credit-eligible.
Every external verification access is logged. The grower sees who pulled their attestation, when, and what they requested. Transparency by design.
Apply DAG-TAT to verify your own farms' water use, SGMA compliance, and water-credit eligibility.
For partners who want to commercialize DAG-TAT verification in a specific crop or region AgWaterAI does not directly serve.
Exclusive rights to DAG-TAT in a tightly-defined slice of the market. Protects the licensee's competitive position without locking out the broader category.
Whether you operate at scale and want DAG-TAT verifying your own farms, or you see a commercial opportunity in a vertical AgWaterAI does not directly serve, the licensing conversation starts here.
