@ -43,7 +43,11 @@ A leader transmits entries during its slot. After `T` ticks, all the
validators switch to the next scheduled leader. Validators must ignore entries
sent outside a leader's assigned slot.
All `T` ticks must be observed from the current leader for that part of PoH to
be accepted by the cluster. If entries are not observed (leader is down) or
entries are invalid (leader is buggy or malicious), a validator should fill the
gap with empty entries and continue with PoH from the next leader.
All `T` ticks must be observed by the next leader for it to build its own
entries on. If entries are not observed (leader is down) or entries are invalid
(leader is buggy or malicious), the next leader must produce empty entries to
fill the previous leader's slot. Note that the next leader should do repair
requests in parallel, and postpone sending empty entries until it is confident
other validators also failed to observe the previous leader's entries. If a
leader incorrectly builds on empty entries, the leader following it must
replace all its entries with empties.
