yeh the so called 'masternode implosion' due to a hack will NEVER happen. why? Because all you can do if you hack a masternode is to 'vote' and perhaps change the payout address for the weekly payouts. but guess what, the user is still in control of the funds.. so he can just shut it down and start another masternode with another public key address.. problem solved.. a compromise of the masternodes does NOT compromise the user funds. The masternode has its own public and private key.
