Round robin is trivially DOS'd . also, sharing your private finance data with your competitors is not an economic efficiency.

Bitcoin isnt good for very much, it's mostly just useful for value transmission and censorship resistance. You're new to blockchains and don't know that, so you intend to blockchain all the things. Which is a way more extreme view.

How is it trivially DOS'd? You don't need to share all your private data just the data about transfers using the system which isn't going to be particularly sensitive unless you are in a bad way financially and will be worth it to minimize the amount of settlements required of your business.

I'm new to blockchains? I'm pretty sure I'm not.
