All well and good. Yet, it’s easy to imagine how peeping Toms could take advantage of this feature to spy on unsuspecting innocents, if they haven’t already. Neophytes who neglect to cover their tracks, for example by sharing their addresses publicly and reusing them, would be easy prey. It’s unsettling enough how much you can find out about someone in 10 minutes of googling. Now add financial transactions, which perhaps say more about people than anything else, to the mix. If crypto achieves mass adoption before privacy leaks are fixed, the result could be a stalker’s paradise.
