layer2 is a great direction in 2022. This year we have seen that type3 zkevm’s Scroll is working hard to switch to type 2.5 or type2; type4’s zksync has begun to gradually shift to type3 zkevm, and launched zksync 2.0; type1 zkevm’s Taiko’s test network is also online. But in fact, a really useful and usable zkevm is still a little far away from us.

As modular public chains gradually become a consensus, the positioning of L2 becomes increasingly important. Based on Starkware, we can also iterate the app chain for L3 and L4.
