Looking at the Cardano explorer I see that every epoch lasts 5 days (21,600 slots in an epoch, each slot 20 seconds). I recall reading that a RNG round is made at every epoch, with the output seeding the next epoch’s slot leader election.
It therefore seems that the RNG “lookahead” for slot leaders is at least 5 days. That is, we know 5 days in advance what the slot leaders will be. Isn’t 5 days a huge amount of time in regards to adaptive attacks? How was the 5-day parameter chosen?
