Overview

sovereign-sdk-sensor is a planned bare-metal component of the Sovereign SDK built specifically for embedded microcontrollers running MicroPython or CircuitPython (e.g., ESP32, Raspberry Pi Pico).

The package exists to enforce Write-Side Custody at the exact millisecond data is born. By sealing physical data inputs (telemetry, hardware logs, system events) into signed, compressed envelopes at the hardware pin layer, it ensures absolute cryptographic provenance before the data ever leaves the local microcontroller unit.

Why It Exists

Traditional edge telemetry architectures suffer from a critical provenance blind spot:

• Vulnerability to Manipulation: Data moving from sensors over local serial lines, SPI/I2C buses, or LoRaWAN networks is untrusted and easily intercepted, injected, or modified out-of-band.
• Payload Bloat: Standard cryptographic structures and verbose serialization formats (like heavy JSON envelopes) exceed the frame size limits of low-power, long-range radio bands.
• Temporal Disconnect: Separating the collection of data from its cryptographic signing creates an un-verifiable gap where historical records can be retroactively altered or spoofed.

sovereign-sdk-sensor bridges this gap by welding hardware-level data acquisition directly to cryptographic lineage validation.

Planned Capabilities

Hardware-Accelerated Micro-Signers

Ultra-lean cryptographic wrappers that interface directly with the on-chip hardware acceleration blocks of modern microcontrollers to instantly stamp Ed25519 or ECDSA signatures onto raw data registers.

The Envelope Serializer

A tight, minified binary framing protocol that packs sensor states, timestamps, and cryptographic signatures into highly compressed, low-overhead packets designed specifically to traverse low-bandwidth pipelines like LoRaWAN or serial interfaces.

Multi-Node Provenance Verification

A matching downstream validation engine that allows an intermediate sovereign-edge gateway to instantly verify the authenticity, node identifier, and tamper-free state of incoming sensor packets.
