Thanks. I would just add that exchanges have been sufficient for traders for centuries (millennia?) before blockchain, including high-frequency.

Can blockchain performance can keep up with high-frequency?: What if I buy an asset then want to sell it before the blockchain has registered the purchase, and then the next person wants to perform a transaction. Where's the proof then?

Even if we brute-force the resources to provide performance for a small exchange, could it scale up?

Maybe my understanding of blockchain performance is outdated or based on certain tech or situations. Or maybe it's a probem on the todo list (normal for a developing tech).
