Optimizing distributed ledger storage and battery usage in iot devices

A computer system for data optimization, comprising:

• one or more processors, one or more computer-readable memories, one or more computer-readable tangible storage medium, and program instructions stored on at least one of the one or more tangible storage medium for execution by at least one of the one or more processors via at least one of the one or more memories, wherein the computer system is capable of performing a method comprising:
• performing a reading at a determined frequency, wherein the reading at the determined frequency is within a bracket parameter;
• determining a bracket value based on the bracket parameter;
• and
• posting the bracket value to a subledger.

A computer program product for data optimization, comprising:

• one or more non-transitory computer-readable storage media and program instructions stored on at least one of the one or more tangible storage media, the program instructions executable by a processor to cause the processor to perform a method comprising:
• performing a reading at a determined frequency, wherein the reading at the determined frequency is within a bracket parameter;
• determining a bracket value based on the bracket parameter;
• and
• posting the bracket value to a subledger.
