He said when its activated, after the spork. Didn't say when.RC5 has a basic version of enforcement built into it that when activated will guarantee masternode payments are present in a block. So far, testing has proven the code is working and we're in the process of working out some of the final issues with it. The code is very simple and when activated the network will simply reject blocks from pools that have not updated.
I hope so.Normally when an RC is released, Evan would post a new update version for wallets. My guessing is when RC5 is released this Monday, we'll see the announcement with updates and instructions for users what to do. At what time on Monday is anybody's guess. Maybe 10AM EST and 7AM Evan's time when he wakes up (like the last time)?
I'm not sure what you mean about "no more bad actors anymore..." ?I hope so.
And I believe there will be no more bad actors anymore...
Do we have to update rc3 wallets to RC4 at least? Wallet.dat I mean.
