High level goals:

  • Feed valid oracle data should be free, and potentially have a reward
    • The reward part will be outside of oracle module, but there should be oracle module should provide necessary hooks
  • Not feeding data should be a slashable event
    • This can be implemented in other module, and oracle module should provide necessary hooks
  • Feeding bad data should be a slashable event
    • This can be done offline combined governance as identify bad action is not easy

Changes

  • Make feed_value / feed_values FreeOperational
  • Implemented SignedExtension
    • validate
      • check sender is valid operator provider
      • check this is the first oracle update tx by sender. i.e. only allow operator to update once per block
      • make it max priority
  • Update OnNewData to include sender
