RE: Why I Don't Talk About The Metaverse Anymore?

hm no not really like SMTs
SMTs aren't even relevant unless HE fails.
SMTs were a technology that was easy to build but just made the cost of running a node too high. SMTs kinda like flying cars. There's no point in making them because they consume too much energy and the chance that they threaten the current system is high.

Forcing every witness to verify generic smart-contracts is massive overkill when we can just create a second layer that even has second layer witnesses and a different subset of nodes and servers. Networks that try to verify everything on layer one aren't going to scale.
