According to ChainCatcher, zkSync, the Ethereum second-layer network based on ZK Rollup, tweeted that the next milestone of zkSync 2.0 - Fair Onboarding Alpha is coming soon, which allows developers to test code in a closed environment. The new fee model can ensure that transaction and block expansion take into account the overall cost of the system, improve proof generation performance and fix all audit findings.

It is reported that the duration of the Fair Onboarding Alpha will be determined together with the ecosystem project. During the Fair Onboarding Alpha, the system will be closed to external users, and after completion it will enter the Full Launch Alpha phase and be open to external users. (Source link)
