I would like to do this:
https://www.youtube.com/watch?v=w9TGkUgekLYBut instead of using 2 Armory installs, with 2 Bitcoin Core installs.
The idea is to have one Bitcoin Core installed in an online computer, this would be my node to broadcast transactions into the blockchain and it would have the full blockchain, but it would have no BTC in it, and another computer with no internet, and no Ethernet or Wifi cards at all, that would have another Bitcoin Core installation, which would contain my private keys, so all of my BTC would sit there. There I would create any receiving or sending addresses and I would sign transactions there, then pass them on the online Bitcoin Core computer.
Could you explain:
1) How do I properly make the transaction and move it from the offline computer to the online computer?
2) How can I set the online wallet to act as a watch only address? (like on Armory does
in here)
3) Is there a way to set the offline node as "offline" so it stops trying to sync the blockchain? since I don't have internet on that computer, is there a way to let the program know that it doesn't have to try to connect to the internet at all? Since there would be no blocks to validate as the idea is to use it as a private key container and to sign the transactions, the program would load so fast on even very old computers (I plan to buy some old Thinkpad for this)
I would use Armory itself, but I don't like the seed system (I don't want my wallet to be recoverable with a seed, I feel safer this way, im too used to have my keys sit on the wallet.dat file and just make backups of that). And in general I feel safer using the Core software, both because I trust the developers into doing a good job, and because simply im too used to the simple GUI it has and don't feel like learning any other GUI's or command lines, so I would like to know how to exactly set this up without screwing up in the process.
