I was wondering whether you bought a piece of hardware (like a VHSIC), which was made with the purpose of running as a BTC node or you just installed a full node in a Linux VM in a general PC.
It is really pointless to attempt to purchase some kind of "specialized hardware". A computer with decent specifications will do just fine as a Bitcoin node.
I was assuming such an option from "mining". As we know, there are several mining specialized HW out there. Why isn't there such HW for full nodes? Since one of the advantages of keeping a full node is security, don't we want to keep it even more secure by pushing it into a HW that is secure at "lower level" (lower = closer to machine level)? Because you know, a regular computer can easily be hacked, infected...etc. Especially if it is the computer, you use for your daily tasks.
