Hello brother.

Great explanations from your side about Layer 2 Blockchain. And I liked your explanation in which you have mentioned that Layer 1 is the foundation and Layer 2 can be used to improve it.

it beats Ether and Bitcoin in terms of fees

That's true. There is almost no fees in the Steem blockchain due to Graphene Layer and It is really good for the users of this platform.

Great efforts. Good Luck for the contest.
