We do not have many POS in YAC now at all, I do not understand why the sudden rush and madness to "fix" POS when there is hardly any POS at all. Has anyone looked at the blockchains that we are comparing YAC to, meaning PPC and NovaCoin, they are 90% POS or more.
Is there are alternate motive behind all this?
Well, the current system isn't safe from doublespends so that's the main motivation behind this.
Question will be how to fix this mess here, or if there's even an acceptable fix for it.
PS: A big part of the problem is that "there is hardly any POS at all"
