Course Introduction:Written by: Stanley, KernelVentures Compiled by: 0xxz, Golden Finance 1. Rollup Track Background 1.1 Track Introduction Rollup is one of the Layer2 solutions. By transferring the calculation and storage of transactions on the Ethereum main network (i.e. Layer1) to Layer2 for processing and compression, The compressed data is then uploaded to the Ethereum mainnet to expand Ethereum performance. The emergence of Rollup makes the gas fee of Layer 2 much lower than that of the main network, saving gas consumption, faster TPS, etc., making transactions and interactions smoother. Some mainstream Rollup chains that have been launched such as Arbitrum, Optimism, Base, and ZK Rollup such as
