# Green Proofs as a Service (GPSaaS)

The Green Proofs system ensures that energy usage is verified as green by managing and validating green certificates for various energy operations. All data sent to workers originates from the Green Proofs application, which transforms it into operations like issuing, transferring, or retiring certificates.
