From the discussion about the anonymously posted Prime Controller keys it seems that when transferring a PC from one person to another there is nothing keeping the original owner from using the same key afterwards. Is this correct? Also, is it possible for the first owner to access the coins in the new address after a transfer? I am specifically wondering if this is the proof that the whole mutiny story and theft of Paycoins/Prime Controllers from Homero is bullshit.
There are 50 prime controller keys. They act like secret passwords which you can say to get 20 times better staking than the muggles.
They are separate from Paycoin addresses. The secret password works to get you 20 times your fair reward whenever you stake an output worth 125k or more.
So yes to your first question - when I let you know the password there's nothing to stop me from continuing to use it as well.
And no to your second question - you and I will be using the same password, but different wallets.
It's not clear to me what a "Prime Controller" is. Is it just a password? Or is it the password plus the wallet containing 125k coins? If it's the latter then it can be stolen. As soon as you "steal" it, you move the 125k coins to a new address that only you control. You didn't steal the password (in that I still have it and can still use it - you only stole it in the Hollywood "copying files is theft" sense of the word) but you did steal the coins.
