Miami to deploy air-quality monitoring on Algorand blockchain

Miami is set to become the first major U.S. city to introduce a decentralized indoor and outdoor air-quality monitoring network built on the Algorand blockchain.

PlanetWatch, a French company specializing in leveraging green technologies, will build an internet-of-things network of third-party compact air-quality monitors throughout Miami, which will transcribe data to the Algorand blockchain. The aggregated sensor data will help detect pollution hotspots and power environmental analytics to monitor Miami’s air quality.

“PlanetWatchers,” or residents who have agreed to host the air quality sensors, will be compensated with in-app tokens and rewards through the network.

Data stored on the blockchain creates a global, permanent, tamper-proof air-quality ledger, officials said. It also allows the platform to track and reward all contributors.

PlanetWatch uses the Algorand blockchain because of its scalability, security and “carbon-negative” footprint. Its proof-of-stake consensus mechanism uses validators – rather than compute- and energy-intensive miners — to verify and record the data, making the Algorand blockchain a green one, according to the company’s webpage.

“The data from this project will play a crucial role in our climate adaptation efforts as well as our ambitions to make Miami an epicenter for digital capital markets.” Miami Mayor Francis Suarez said.
