Your article I did read about the layer-3 blockchain and how they get big is awesome. It isn't boring because you present these layers with an explanation like Layer 1 for Bitcoin and Ethereum, Layer 2 for more functionality and Layer 3 for ultra-level scaling.

The points about sharding, prims for storage, fractal trees for saving data, and rollups for squeezing the transactions in a decentralized system is also easy to comprehend. It is fascinating that layer 3 blockchains employ horizontal fork into different chains to be able to processed many transactions at one time. However, if you compare this with Steem blockchain, you can see a great dissimilarity between Steem's way of decision by witnesses and Steem's way of doing thigns by moving up instead of doing things sideways.

The idea about sidechains and rollups to make Steem just that much better that it is is smart and shrewd. Came last, the one about the capability of layer 3 blockchains and Steemit to make the decisions of the community and incorporate it seems interesting. You created a good content.
