- How far ahead can the leader schedule be disclosed at minimum and at maximum?
- Which block’s nonce is the epoch nonce based on?

Proof of Leadership
- Why does Cryptarchia use a Merkle tree of height 25 for the note secret key instead of the Crypsinous paper’s suggestion to use a tree of height 24?
- What are the pre-computed thresholds $t_0$ and $t_1$ in the PoL?
