Contents:

  • Peg entries and exits to epoch boundaries
  • Add a store of historical active index roots
  • Mix it into the randomness
  • Remove the delta hash chain

Note that the actual light client implementation is beyond the scope of the spec.

[Note to reviewers: verify that the invariant added in the PR is correct]

Question:

  • Do we want to also only store epoch-boundary randao values? I don't think we use the epoch-intermediate ones anywhere.....
