I write here about some of the growing pains of decentralization that should be addressed:
I think it’s a good idea to bump this to 300, as in the wider cosmos there are more validators, and many would love to join to secure the hub to provide shared security.
I would also love to see if we can explore bigger numbers of lets say 1000, or 10s of thousand. This still needs to be battle-tested as tendermint does not recommend a very big set as it requires 66% to come to a consensus before a block is committed, meaning this could increase block times. I would also like further development in this space (From tendermint).
