A vulnerability that could have permitted an attacker to coin infinite Zcash (ZEC) has been patched and disclosed by the company behind the coin, a post on the official Zcash blog states on Feb. 5.
Ariel Gabizon, an engineer at the Zerocoin Electric Coin Company — the startup behind privacy-focused cryptocurrency Zcash — reportedly discovered the vulnerability the night before his talk at the Financial Cryptography 2018 conference in March 2018. Gabizon contacted Sean Bowe, a cryptographer at the Zcash Company, the same day.
