【 摘 要 】

On May 12, 2017, at roughly 12:30 p.m. British SummerTime, England’s National Health Service (NHS) was invaded by WannaCry, a ransomware attack. To this day, this cyberattack remains the largest one affecting the NHS.1,2 An estimate ofnearly 20,000 patient appointments were cancelled, and 595 general practices were infected.2 Soon, news about this attack raced toheadlines, and with it, so did Bitcoin, a relatively new type of currency. The attackers had encrypted computer files, making themunreadable to human users, and proceeded to demand 300 dollarsworth of bitcoins for decrypting each computer. This demand foran exchange through Bitcoin brought the seemingly mysteriouscryptocurrency to the foreground of the public sphere.
