- `justified_checkpoint`: the justified checkpoint being used as the starting point for the LMD GHOST fork choice algorithm.
- `finalized_checkpoint`: the highest finalized checkpoint that was seen. In general, the fork choice will consider only those blocks that are not conflicting with this checkpoint.
- `unrealized_justified_checkpoint` & `unrealized_finalized_checkpoint`: these track the highest justified & finalized checkpoints resp., without regard to whether on-chain ***realization***, i.e., FFG processing of new attestations, has occured. This is an important distinction from `justified_checkpoint` & `finalized_checkpoint`, because they will only track the checkpoints that are realized on-chain. Note that on-chain processing of FFG information only happens at epoch boundaries.

- `unrealized_justifications`: stores a map of block root to the unrealized justified checkpoint observed in that block.
