Not exactly sure how this works. Something along the lines of...

  • Read the latest block's header
  • Extract digest logs
  • Read latest Babe pallet authorities (could be different consensus though...)
  • Iterate over authorities, decoding...
  • ...

Do we have anything bullt in already that can decode logs?

Might require a hand-written codec that decodes the leading text (a union of non-scale-encoded consensus names) followed by validator public keys (I believe).
