What are the risks of running a full node with encrypted wallet out of an OpenVZ cloud VM?
I understand a server administrator could retrieve the encryption key (passphrase) from RAM (or from shell history if I use it to unlock the wallet), but what if I unlock the wallet from another computer via RPC, create and broadcast a transaction on that VM, and then lock it again?
Would this leave the wallet encryption passphrase in RAM somehow? What are the risks?
Thanks in advance for any insight.
