Please share with the class how?

Look into nxt, peercoin, a few of the other pos chains. They all failed due to stake grinding. read the poelstra papers for why pos is untenable

When you know every participant you don't need PoS or PoW you can us RR.

Like I've said elsewhere you are arguing from ignorance and because you've bought into the religion of bitcoin.

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.

Look into paxos and raft attacks. You don't know enough about this science to promote it as the cure for what ails you.

As for sharing information - youre right... if you don't use blocks

"RR is trivial to DOS look at these two other schemes and the fact you didn't means you don't know what you're talking about".

I think we're done here. You're not doing anything but saying Nu uh! and calling me a liar.

So you're telling this forum that the innovation here is round robin signing of network state.(not even a decent trusted consensus system like raft) I can't imagine that any halfway competant programmer in here will buy this as anything more than a trivial code construction.

Here's what will happen to your database: it'll drop the blocks and revert to a message passing infrastructure. Which is fine and good - but not in any way related to a blockchain.
