What do you think of rollups as the L2 scaling solution for Ethereum?

User activity on ETH has seen slow growth due to ETH’s high gas fees, not surprising, right? I noticed that plenty of users prefer to use Solana and Avalanche as gas fees on all of these chains cost less than a dollar. ETH has less throughput also in comparison to other Layer 1 blockchains.

Various scaling solutions can help in boosting the growth of ETH's ecosystem. But what I've heard is that the rollups have shown the most potential as a scaling solution out of all of these. They can solve significant problems for ETH users, which are high gas fees and less throughput.

I've noticed over time how rollups are enabling transactions at a low cost and have a high throughput capacity without compromising the security as settlement of all the transactions executed on rollups happens on ETH. ETH can act as a settlement layer of the ETH ecosystem while rollups are used as an execution layer.

You know how processing is sluggish, optimistic rollups can boost scalability by up to 10-100x, depending on the transaction. With the advent of shard chains, this figure will rise even further, as more data will be available if a transaction is challenged. The two most widely used optimistic rollups are Optimism and Metis, which allows us to provide extraordinarily quick transactions that take only a few seconds and cost only a few cents while yet preserving ETH Layer 1 security.
