The reason for all the excitement is that L2 solutions, such as #optimism, will help increase #Ethereum throughput (tx per second), decrease latency (how long it takes a tx to be confirmed) and significantly reduce rates of gas.
All without losing the security of the main #Ethereum network. This is the main difference between "side chain only" solutions and real Layer 2 solutions. Side chain solutions have their own consensus and security mechanism, and do not benefit from ETH layer 1 security, whereas L2 solutions of.
