Cosmos chains take a DPoS flavor on top of Tendermint, and the philosophy is to prioritize decentralization among a small set of delegates to achieve max efficiency in on-chain governance and responsiveness to events

All PoS systems have theoretical limits on how far the validator set can scale per shard before performance starts to degrade significantly - so the only options are to scale vertically (increase hardware specs) or horizontally (segregating state machines in shards)

In some sense, the hub and spoke design of Cosmos / IBC is intended to horizontally scale in "branded shards" - each cosmos state machine has a sovereign set of rules, but they all speak a common language to sync important state via IBC

So in some sense, horizontal scaling through branded shards in cosmos is already feature complete - the new challenges will be, how can you build apps that are agnostic to the shards that underly them? I.e. now that you've scaled the machine, how can you scale apps?

In the beginning, developer ergonomics is going to be a bit janky - apps may need to "be aware" of what state lives in which zones - but it's not a very difficult problem to eventually abstract this away

It's a bit awkward for me to move to a chain half our mktcap
Something something value preservation

yeah, that can be revisited soon
