Assalamualaikum brother!!

Well explained and well balanced explanation of the topic. Layer 2 chains can be used to process the transactions of the main chain and hence the load from the main chain is reduced with helps in increasing the TPS .

You are right that the attraction of the Steem blockchain will be increase a lot if the layer 2 solutions are implemented here. Anyways, the official devs know better in this regard.

Good luck man 👍
