Ground truth, signed at the source.

Hardware-signed environmental sensors built to settle real-world outcomes. Every reading is signed at the device in a tamper-resistant element and anchored on chain, so it is auditable before it reaches a market, a policy trigger, or a registry.

01 · The System

Core. Soil. Atmosphere.

One signing architecture across three sensing layers. Each node binds device identity, timestamp, location, and calibration state into a single cryptographic digest before any reading leaves the hardware.

01
Core Hub
Signing & Uplink
Dual-radio LoRa and NB-IoT hub with a tamper-resistant secure element. Solar charging, full-color status display, dual sensor ports, industrial weatherproof enclosure.
02
Soil Sensor
Root-Zone Telemetry
Stainless probe measuring pH, moisture, temperature, and electrical conductivity at the root zone. IP67, 15 m cable standard, extendable.
03
Atmospheric
Weather & Air
Wind, rainfall, humidity, and air-quality metrics for hyper-local weather tracking and hazard sensing.
02 · Hardware

Field-deployed. Signed at the device.

The system ships as a complete deployment kit. Every cable, mount, fastener, and accessory is included. Unbox, configure, deploy.

03 · Proof of Origin

Sign the measurement, not the report.

Legacy MRV signs a PDF at the end of a 12 to 18 month cycle. Malama signs the reading at the instrument, the moment it is taken. The signature, not the spreadsheet, is the source of truth.
