We catalog and preserve all relevant publicly available data, data from the aqa.earth sensor network, and modeling data on private servers situated within the EU. To guarantee data immutability, we store their hashes on the public Algorand blockchain using our AQA token.

This method combines data immutability with the highest possible speed of data access, which is crucial for real time simulations and predictions of soil and water quality using physics based models, machine learning and AI.

The AQA ecosystem, launched in June 2022 on the Algorand public blockchain, is designed to secure the integrity of data and to compensate contributors to aqa.earth through micropayments. Following comprehensive testing in 2023, it is now fully operational across all aqa.earth projects, ensuring the immutability of data records for all the information we gather and produce.

The system is crucial for both scientific research and practical applications in farming, natural environments, urban areas and aquatic areas, providing a reliable and transparent platform for our diverse community of scientists, agriculturists, local authorities, and citizens.



All data collected by our sensors are automatically assigned a unique hash that is stored on the Algorand blockchain on a daily basis. Given that each sensor possesses a distinct Algorand address and that each hash transaction involves an AQA micropayment, we establish a robust indexed AQA framework to guarantee the immutability of our data. This system not only underpins the credibility of our work but also strengthens the trust in our ecosystem among scientists, agriculturists, local authorities, and citizens.
