I&#x27;m talking about trades specifically.<p>A trading platform must have a 1:1 mapping of buyer to assets when trades are agreed. You cannot have a situation where two people buy the same share, as it requires unwinding. A trade must be atomic.<p>traders want to see all the bids&#x2F;asks of the whole market. Otherwise you&#x27;ll effectively have a random assortment of tiny markets under one supposedly united trading platform.<p>Thats the other thing, trades need to be reversible. There is a good correlation between massive trade volumes and the need to reverse transaction. Having an eventually consistent model is just not going to work.<p>Being overdrawn is not eventual consistency. The act of an overdraft is not a failure of a bank to properly account for your balance, its a deliberate business move to generate cash.<p>So no, its consistency, one price, one bid, one ask.
