Going to cast all my stupid questions in this thread as they come up 🧵👇

>The right number is probably 10 - 20 globally distributed write hubs

What was the reasoning behind this statement?

Have you looked into PoS mechs that emulate PoW via slots where block producers are elected using a rng? Eg. Ouroboros 

I think 20 feels too low because a nation-state level actor could take down 10 nodes if they had strong desire

Needs to be sufficiently large enough that 1/3 of the network can safely fail at any time (so rolling updates don't threaten the network's uptime), but not so large that the consensus algorithm ends up being over encumbered and cannot handle volume (a real issue in any pBFT approach and why you see the pBFT-based networks touting 100k tps only have a handful of validators — validator count is inversely proportional to throughput under pBFT approaches)
