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.
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.
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.
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.
Verified data. Many markets.
Deploy verified sensing.
