In previous posts, we highlighted some interesting DePIN projects on the Polygon, Solana, and Cardano blockchains. Today we will be covering an environmental DePIN project based on the Solana blockchain.
Ambios Network (previously Ambient Network) is a Decentralized Physical Infrastructure Network (DePIN) focused on environmental monitoring, collecting real-time air quality data through a global network of over 17,000 low-cost sensors.
By deploying thousands of citizen-hosted air quality nodes, the Ambios Network is able to achieve cost efficiency and coverage that scales.
Their vision is to build the largest decentralized environmental data network, empowering AI and the machine economy.
Ambios Sensors
A variety of low-cost air sensors can be purchased from the Ambios website for approximately $100 each.
The sensors monitor properties such as PM2.5, CO2, VOCs (volatile organic compounds), temperature, and humidity in order to measure both indoor and outdoor air quality.
By installing and maintaining a sensor, the operator earns Solana-based $AMBIOS tokens for contributing real-time air quality data to the network.
Solana Migration
Operating on the Solana blockchain (after a strategic migration from Algorand in late 2024), the Ambios network provides transparent, hyperlocal environmental data to communities, enterprises, AI platforms, and data marketplaces.
The project's token was migrated to Solana in order to achieve higher throughput and lower costs. Solana’s speed and low latency supports Ambios Network’s frequent microtransactions.
AMBIOS Token
The AMBIOS token was launched in Q1 2025 with a 1 billion token cap. Users are rewarded in AMBIOS tokens for contributing data via sensors or the project's AmbiGo! app.
Tokenomics
40% of the total supply has been allocated to the network miners, with the remainder pre-allocated to the foundation, insiders, and investors.
Contrast this to Bitcoin, which had no pre-mine, and where each community member had to actively participate in the project in order to earn coins, and Ambios could be considered somewhat centralized.
We discussed the dangers of centralized initial token allocations in previous posts.
The Ambios Network token rewards will halve every year until 2035 when the total supply of mining rewards will reach the allocated 400,000,000.
Silencio and WeatherXM
In addition to Ambios, there are other DePIN projects that are focused on monitoring the environment.
Similar to Ambios, Silencio is a DePIN that targets environmental monitoring (noise pollution vs. air quality) and leverages a decentralized network of sensors (within existing mobile phones). Silencio is based on the Peaq blockchain, instead of Solana.
WeatherXM is another Solana-based DePIN focused on environmental data collection (weather vs. air quality) and uses a community-driven model with blockchain-based incentives.
Until next time...
Although the Ambios Network is still in its nascent stages, and the initial token allocation has yet proven to be viable long-term, this project may be worth keeping an eye on as we transition into the new crypto-powered decentralized economy.
