Hi @yancar
You have created the post very well and I always learn something every time I read your post because some points are so finely observed that it is really noticeable. And I appreciate this post

Layer 2 solutions parent blockchain ki scalability ko increase karne mein bahut aham kirdar Ada kar sakte hain aur yakinan yah iska bahut aham use case hai.

Layer 1 or layer 2 me main difference yahi hai ki layer 2 ka men focus blockchain ki security aur transparency per hota hai jab ke layer 2 ka men focus blockchain ki scale ability ko increase karne per hota hai.
Always be safe
