The Pros and Cons of Proof of Stake Blockchains

I think the only con of cosmos is essentially, you know this that it's still Expensive to launch a new chain because you have to bootstrap a new validator set and proof of stake network. You can't actually know what the malicious stake is and to me that's really problematic as well. So again, Celestia You can launch a chain without bootstrapping a new network and you can have shared security. And I think those two things are really going to be like they're going to turbo charge the the cosmos vision of like an internet of blockchains.
