Layer 2 Scalability Explained: How ZK-Rollups Measure Up to Subnets


In recent times, popular Layer 1s (L1s) like Solana and BNB Chain have succumbed to network outages as a result of the concurrent running of DeFi protocols, NFT marketplaces, and web3 games on their respective networks. In a similar vein, Ethereum has also been constantly criticized for the issues of network congestion and expensive gas fees that have been plaguing its network. From this, the space began to realize the importance of Layer 2 (L2) scalability solutions.

According to the Ethereum Foundation, rollups are currently the preferred L2 solution for their scalability issues. On top of rollups, other L2 solutions like sidechains and subnets also exist to tackle the scalability trilemma.

In particular, Subnets, Avalanche’s L2 scalability solution, have gained quite a bit of popularity in recent times with the deployment of the DeFi Kingdoms and Crabada subnets earlier this year. For some context, subnets are essentially sidechains, with the exception that subnets can choose to employ validators from the mainnet. Currently, subnets and sidechains seem to be favored by web3 games as their go-to L2 scaling solutions.

With all these different L2 solutions floating around in the space, how do they actually stack up against one another? In this article, we will dive into the rollups landscape to discuss the latest  developments and pain points within said landscape. We will also analyze rollups in relation to custom chains (subnets or sidechains), and look at how these various L2 solutions actually stack up against each other, particularly in the GameFi space.
