Greetings friend,

Wow, probably it is the best entry I have read until now. You have explained every important concept of the layer to solutions in a very beautiful and understandable way and even newcomers can find it easy.

You are right that the main difference between the layer one and layer to blockchain is that the layer 2 mainly focus on the security and transparency of the blockchain while the layer 2 solutions have the missions to improve the scalability and communication with other chains.

Good luck ahead 🤞
