The Freshwater Trust (TFT), a 501(c)(3) nonprofit working to protect and restore freshwater ecosystems, is partnering with IBM Research and SweetSense Inc. , a provider of low-cost satellite connected sensors, to pilot technologies which can accurately monitor and track groundwater use in one of the largest and most at risk aquifers in North America. Additional research support will be provided by the University of Colorado Boulder.
Jointly funded by the Water Foundation and the Gordon and Betty Moore Foundation, the project’s scientists and engineers will demonstrate how the blockchain and remote IoT sensors can accurately measure groundwater usage transparently, and in real-time in California’s Sacramento San Joaquin River Delta.
The sensors will transmit water extraction data to orbiting satellites and then to the IBM Blockchain Platform hosted in the IBM Cloud. The blockchain will record of all data exchanges or transactions made in an append-only, immutable ledger. The blockchain also uses “smart contracts,” whereby transactions are automatically executed when the conditions are matched.
