RE: Qtum Staking Tutorial using qtumd on a Raspberry Pi 3
Thanks for the great guide! It seems like if you're dedicating a Raspberry Pi to nothing but QTUM staking it would make sense to not encrypt it. If I understand correctly, encrypting it makes it less likely to remain staking in the event of a reboot (e.g. power outage), and also introduces the need for re-entering an unlock password whenever the unlocked_until expires. Is it possible to encrypt it so and unlock it with a command line option that mentions it should remain unlocked for the next 365 days even in the event of reboots?
I do recommend encrypting your wallet, but I have another guide to cover that.
I'd be careful leaving any trace of your passphrase on the Raspberry Pi. Instead, it's better to have a watchdog process to inform you if the
qtumdprocess goes down or if theqtumdPID changes (so that you can manually bring it up again, then securely unlock it). This topic is a bit more advanced though... but you have the right idea.
