So you know ahead of time each transaction is going to interact with a set of UTxos As long as those UTxos are not overlapping You can basically, you know verify separate transactions in parallel. So I'm super excited just for the ability for people to create custom virtual machines Our execution environments and play around with those different parameters and learn and see what works and what doesn't work so that would be very cool. And then maybe like continuing on like the execution and like um virtual machine sideUm, how do you kind of see like zk's versus like optimistic like combined with like the execution environment? Mm-hmm. That's a really really good question and where things
