Even Privacy-Focused Cryptocurrency Can Spill Your Secrets
From a Harry Potter-themed protocol to high-profile coins, cryptocurrency is often not quite as private as it seems.
Privacy coins are a reaction to the realization that bitcoin isn’t private at all. All bitcoin transaction data is public and open to all for analysis; combine that with some strategic subpoenas to get the personal data cryptocurrency exchanges are required to collect on their customers, and it’s pretty trivial to untangle who’s who. But also privacy focused couns like Grin and Beam have their flaws, as research shows.
