What is Native Rollup? 🔻

We need to first understand that Rollup has three modules: data, sorting, and execution. Native Rollup directly uses Ethereum's own execution environment to run its execution module. In simple terms, they can be regarded as programmable execution shards on the first layer (L1).

It sounds a bit confusing to want Rollup to use the execution function of L1. To put it bluntly, you have to run another EVM in the Ethereum EVM. In this way, L1 can know what the state changes of each block of Native Rollup are. To achieve this, there must be a precompile to help turn this idea into reality.
