ByBit has released its report on “Layer 2 Scalability Explained: How ZK-Rollups Stood up to Subnets”. The report looks at how these various L2 solutions stack up against each technology solutions. Rollups combine compressed off-chain transactions into a single order on an L1 network in order to cut gas expenses and increase transaction capacity for any given transaction. This means that the L2 may execute transaction computations while the L1 just needs to execute computations. Web3 games' preferred L2 scaling methods seem to be subnets and sidechains at the moment.
