One interesting news came out today. I can't fail to mention it here.

Tomorrow,
March 13, the Dencun update will take place on the
Ethereum network, its main goal is to reduce commissions in
Layer 2 (L2) solutions.
The effect of lowering commissions is planned to be achieved through "
proto-darksharding" - a new type of transactions in rollups that combine so-called binary objects (
or blob-objects).
