"The different types of ZK-EVMs"

In the current stage, trade off between compatiblity and performance must be made when implementing zk-EVM. But different types of EVMs could co-exist to make the blockchain more scalable in different aspects.

Type 2's future market dominant makes most sense to me, it basically preserves the EVM environment while improves a lot on the prover time. Only the stuff from outside, like block structure and state trees are not compatible. Polygon and scroll are building towards this kind of EVMs.(Their product is about type 3 in current state)

“不同类别的ZK-EVM”

在当前阶段，实现zk-EVM时必须在兼容性和性能之间做出权衡。但是不同类型的EVM可以共存，以使区块链在不同方面更具可扩展性。

对我来说，类型2的未来市场主导地位是可预见的，它基本上保留了EVM环境，同时大大改善了证明时间。只有来自外部的内容，例如块结构和状态树不兼容。Polygon和Scroll正在构建这种类型的EVM。（他们目前的产品属于类型3）
