w/o reading your blog (I'm sure it's great will read it later)
my thoughts on "fast finality" are similar to ultra fast scalable alt l1s. in the worlds of donnoh, ask where the fast finality comes from
They get this "fast finality" because they have anywhere between 4 to 20 validators, this isn't HARD finality this could easily get reorged easier than ethereum when it's not technically not in finality
