Global increases in anthropogenic emissions of pollutants have resulted in sometimes hazardous fluctuations in air
quality worldwide. This has led to a need for a publicly available, scalable, and tamper-proof pollution monitoring system for use
by authorities, private citizens and researchers alike. In this paper, we investigate the applications of blockchain in such a system
and propose a prototype that attempts to meet all of the above criteria. It is designed to be fully decentralized by using the
Blockchain to store and retrieve the data recorded by IoT sensors.
