Introduction

Raiznet is a decentralized network for crop monitoring and collective agricultural intelligence. It is part of Arateki's SafraSense product. Data flows from ESP32 sensors installed in growing towers to a mesh of server nodes, and can be read by any member of the network — with or without their own node. Nodes are designed to sync with each other peer-to-peer; see the Roadmap for what is implemented today versus in design.

Beyond monitoring, Raiznet is designed as a research-grade data infrastructure. Every reading is signed, tamper-evident, geolocated, and linked to a planting outcome. Over time, this creates a collective dataset that LLMs and researchers can turn into actionable knowledge: better crop parameters, regional calibrations, and scientific publications — owned by no one, available to everyone. See Collective Intelligence for the full vision.

Non-negotiable principles

1. Local-first. The network works without internet. An ESP32 and a laptop on the same Wi-Fi are already a valid Raiznet.
2. Data sovereignty. The user owns the keys. If Arateki disappears tomorrow, the grower's data stays alive in their node.
3. No traditional login. Identity is an Ed25519 keypair generated on the client. There is no central authentication server.
4. Device ID is always public. The only information guaranteed public is the existence of a device in the network — its pubkey, MAC, and basic metadata. Everything else has an individual visibility policy defined by the owner.
5. Private data is local data. What is marked as public is eligible for replication across the network. What is marked as private stays in local storage — it never leaves the owner's infrastructure.
6. Public or local network. The public Raiznet is the global mesh of public nodes. A "private network" is a local network: the server doesn't announce itself, it only accepts LAN connections.
7. Writes are always signed. Reading is a consequence of belonging to the network. Writing requires the private key of the emitting device — prevents spam without depending on central permission.
8. Server is optional. Nobody is required to run a node. But whoever does strengthens the network.

What Raiznet is not

• A cloud service. There is no Raiznet-operated server you must trust.
• A blockchain. There is no global consensus, no mining, no tokens.
• A traditional IoT platform. There is no vendor lock-in, no required API key, no usage limits.

Part of SafraSense

Raiznet is the open protocol and network layer of SafraSense. The production firmware for Arateki hardware lives in a separate repository. This repository contains:

• The protocol specification and wire format (this site)
• The Node.js server implementation
• The reference ESP32 firmware (firmware/)
• The CLI for operations and debugging
