A method of down-sampling time-series data may include receiving energy usage data representative of energy usage of a customer during a specified period. The energy usage data may be signed with a digital signature of a utility. The method may also include receiving input from a customer effective to select a granularity level to apply to the energy usage data and the energy usage data may be down-sampled to apply the selected granularity level to the energy usage data and produce down-sampled energy usage data. The method may also include communicating the down-sampled energy usage data and hash values of child nodes corresponding to the down-sampled energy usage data to a third party. |
