I was scrolling X and I saw “Layer 2 solutions” trending. I won’t lie I had to pause. Every week, they drop a new term on X. First, tt was blockchain and now it's layers again. They say it's there to make transactions faster and cheaper, but why not fix the main system first? It feels like a patching to me.
