I idea is to have the 10000 DMD "sequestered" in a more secure wallet that periodically checks-in with a live instance that does all the transaction processing.
Great idea, unless I kick the live instance in the nut-sac 1000 times a second - effectively wasting your time and money.
u just need a 3$ VPS and u dont need max security because the node have no coins inside
the wallet that really have the coins just must be online a short time to start the masternode then it can go offline again
the control wallet need no static IP and dont need to stay online
can be hidden as good as u can hide it
with this kind of masternode setup u can control and start multiple masternodes
with 1 high security controll wallet (that really hold coins)
and for each MN a low security public visible 24// online MN
basically how it work is the controllMN wallet with the ral coins start the MN in network is able provide the proof of coins and have all required keys
but it state that it operate and at the IP of the workingMN VPS
so after start the MN the controll wallet can go offline and the online empty MN will continue to handle the work
this is no exploit of the system its perfect fine and secure
because if the controll wallet would move the 10k DMD then the workingMN would also be seen as invalid MN
so u cant trick the system but u can run save MNs 24/7 because in fact they are empty on their local wallet.dat is no coins
even the rewards it earns arrive at real MN
if u set up and provide such a service to host the MN for people who dont want to care
and just remote control start stop MN with their control wallet then i think this will be a great service that find a lot user
but u should have a website that explain all the stuff to ur users and help them to set up the remote control wallet
and which data they must provide u to run the VPS coinless workingMN
u (and others with proper background to able create such a service) invited to join testnet in late testnet state
to prepare yourself if u interested follow up this business idea
