Oddbean new post about login | logout I am think sidechain scaling is the way to go like BIP300 or BitVM. Maybe rollups if they are actually trustless but rollups atm are centralised.
Don't you think side chains will open Bitcoin for new unexpected vulnerabilities?
It moves all the complexity to sidechains to deal with. Something goes wrong on l2 doesn’t affect l1. Whereas lightning is closely tied to l1.
