Abstract

Update fork choice rule with IMD GHOST algorithm.

Proposed implementation

New ScoreFunction should be implemented that uses IMD GHOST algorithm combined with finality.

Beacon chain fork choice rule is outlined in the spec.
IMD GHOST is well described by following posts:

As finality is not yet implemented, there is a suggestion to use block with a highest slot number that satisfies condition <= head.slotNumber - CYCLE_LENGTH as highestSlotNumberJustifiedBlock
