Summary:

Context

As per PC Translator design, we need a runtime library will be called during PC run. This library will be called at the beginning of PC run to encode specified fields in publisher side input into a encoded breakdown (aggregation) Ids based on active PC instruction sets for the run. The library will filter the active PC Instruction sets for the run based on parsing the pcs_features i.e. gatekeepers for the particular run.

Product decisions

In this stack we would focus solely on functionality required for private lift runs.
We would focus on the MVP implementation of the library and its integration with fbpcf ORAM encoder library in this stack.

Stack

  1. Create runtime pc_translator library.
  2. Add logic to retrieve and parse PC instruction set, filtered based on the active gatekeepers for the run.
  3. Integrate pc_translator library with fbpcf ORAM encoder.
  4. Add logic to generate transformed publisher output with encoded breakdown ID and write the output.
  5. Add support for filter constraints in pc_translator.
