Will L2 help ethereum ecosystem grow ?

The Layer 2 war is heating up. This comes as no surprise as a ton of projects are trying to steal a piece of Ethereum’s pie by leveraging on network and trying to improve its current state. But is there a clear winner emerging from this battle? Let’s dive right in.

There are plenty of projects out there that is related to Ethereum layer 2 solutions – generalised L2s (Polygon, Arbitrum, Optimism) and application specific L2s (dYdX).

The 5 projects that I will be comparing are dYdX, Polygon, Optimism, Arbitrum and Loopring.
