    I will admit that my understanding of cryptocurrency is limited, but it seems to be vulnerable to a botnet attack, wherein malware silently infects devices that validates/stores transactions, and manipulates their ledgers simultaneously. Is my theory bunk, or is it a real threat? If you could manipulate enough ledgers at enough nodes, wouldn’t this be feasible? Do we think something like this might be underway?

    Yes, it’s been talked about. Google “51% crypto attack”

    There would have to be an exploitable vulnerability in the bitcoin node software to allow an invalid transaction history to be accepted. Each node runs the software, and the validation checks they perform are pretty basic math. So it would have to be a pretty foundational vulnerability that is already out there on the nodes, exploitable through some sort of broadcast input that itself isn’t validated. Not impossible, but unlikely
