# Data Collection Layer (Decentralized Data Collection)

###  Decentralized Weather Stations

* Deployed globally by individuals, communities, and organizations, capturing hyperlocal physical signals such as temperature, humidity, wind speed, air quality, and solar radiation.
* Data is grouped by geo-grids (e.g. 10° × 10°), packaged daily into datasets, and assigned unique CIDs (content identifiers).

**Multi-source Inputs**

* Supports diverse IoT data streams beyond weather, including energy output, agriculture, freight, and physical sensors.
* Token incentives encourage broad participation, expanding coverage and diversity.
