The Greycore timeline is a relic of Ren 1.0 (the bridge); a milestone of the protocol having achieved enough stability to progressively decentralize. With the shift to Ren 2.0 (the L0/L1), the protocol is now anything but stable; it’s under intensive R&D. And there is nothing more insecure than decentralizing unstable software.
So, the questions I would ask are: if Ren 1.0 were secured by an expanded Greycore today, how would it affect the security of Ren 2.0? Would 2.0 need to be secured by the Greycore upon launch? If so, that would be a change in Labs’ historical approach towards progressive decentralization. Or could the two be bifurcated such that the Greycore could secure 1.0 while Labs progressively decentralizes 2.0 on a different schedule? Perhaps this would be an argument in favor of subnets.
Let’s be sure to keep a holistic view of the Greycore in our conversations and questions for Labs. In the meantime, let’s keep this RFC focused on 2.0.
