# L3区块链OPSIDE交互教程

当L2项目遍地开花的时候，已经有团队在重点研究L3了，币圈讲究先机，快人一步就是快人百步（团队暗示会有空投）。

opside提出了一个 3 层区块链架构，其中第 2 层是 EVM 兼容且对 rollup 友好的链，第 3 层由多个 zk-rollup 组成。该链针对 zk-rollups 做了很多系统级的优化，引入了[native rollup](https://ethresear.ch/t/native-rollup-a-new-paradigm-of-zk-rollup/14529)的概念。基于此架构，Layer 2 从桥接中获得资产多样性，从 Rollup 中获得无限扩展性，为应用程序提供更友好的运行环境。
