The cryptographic verification chain
for agricultural sensor data.

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.

DAG-TAT in one screen

Three things every verification system needs to do.
Most do one. DAG-TAT does all three.

01 · What it is

A cryptographic recording chain for sensor data.

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.

02 · What it produces

A portable, third-party-verifiable proof artifact.

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.

03 · What it unlocks

Procurement-grade water-credit and compliance markets.

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.

Architecture

How a soil-moisture reading becomes audit-grade.

01

Reading ingest + signature

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.

02

DAG node construction

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.

03

Merkle root per attestation window

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.

04

Auditor co-signing

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.

05

Audit log + access ledger

Every external verification access is logged. The grower sees who pulled their attestation, when, and what they requested. Transparency by design.

Markets DAG-TAT opens

Four enterprise revenue lines depend on this chain.

💧
Hyperscaler water credits
SCS GLOBAL · BEF · VWBA 2.0
Microsoft, Google, Meta, Amazon water-replenishment programs need audit-grade measurement to qualify in-situ agricultural savings. DAG-TAT is the only ag-source in-situ MRV the methodology accepts.
📈
Parametric crop insurance
ARBOL · DESCARTES · MGAs
Compliance probability and dollar-denominated exposure become parametric triggers no satellite-only product can produce. DAG-TAT-backed reads are the trigger underwriter counsel will accept.
🏦
Farm Credit underwriting
AGWEST · AMERICAN AGCREDIT
Loan officers underwriting SGMA-exposed borrowers need court-admissible compliance evidence. The attestation packet is the artifact their credit committee asks for.
⚖️
SGMA regulator audit
SWRCB · GSA · DWR
Probationary-basin reporting requires defensible measurement. The DAG-TAT chain plus auditor co-signature gives regulators a record that survives litigation. Currently the only product producing this.

Licensing

Three ways to license DAG-TAT.
Each priced separately. Each negotiable.

Operator
Tier 1 · Use license

For your own farm operations

Apply DAG-TAT to verify your own farms' water use, SGMA compliance, and water-credit eligibility.

  • Per-site annual subscription. Includes attestation packet generation, external verification API, audit-log dashboard.
  • No sub-licensing rights. Use is for your operations only.
  • Same DAG-TAT chain AgWaterAI runs in production. Identical attestation artifacts.
  • Pricing: typically $200K-$500K/yr depending on site count and verification volume.
Exclusive
Tier 3 · Narrowly-scoped exclusivity

For a strategic carve-out

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.

  • Exclusivity scope defined by crop × geography × use case. Strict definitional boundaries.
  • Term-limited (typically 3-5 years) with renewal optionality.
  • Includes ROFR on adjacent verticals at renewal.
  • Pricing: $10M-$50M+ depending on scope. Priced as a real IP transaction, separately from any equity discussion.

Most agricultural data is unverifiable.
Yours doesn't have to be.

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.
