Sharding. An Adversary or Friend to Layer-2s(L2s)?

I have been asked a lot of questions about Ethereum and the future of its Layer-2s or Sidechains especially, Polygon (Matic). And with the unrest with the indefinite delay to ETH2.0, there are questions about the reasons for the delay and will its delay be worth it in the end.

After what happened with the London fork, it’s understandable why Vitalik and his team are taking their time on ETH2.0.

What happened with the London Fork?

London Fork or London Hard Fork was the first step toward the ETH Merge(Move to PoS). EIP 1559, precisely was supposed to make ETH deflationary and its gas fees predictable and less volatile. Many were also expecting lower gas fees.

In order for ETH to combat its rising inflation, they had to burn a lot of ETH combined with the strain on the blockchain, the prices of ETH spiked. And so did the gas fees and it led to a mass exodus from ETH to other blockchains that offer lower transaction fees like Solana.

I am going to give a quick breakdown on what are Layer-2 Protocols and Rollups for people confused with the concepts.
