Accused of unlimited minting? ZEC, known as the privacy version of Bitcoin, had its founder confirm a critical vulnerability in its privacy system that could have allowed attackers to create an unlimited amount of ZEC, with no way to trace it due to its privacy features. This vulnerability existed from May 2022 until it was fixed on June 1 this year. No one knows what happened during this period, leading to sharp fluctuations in the ZEC token price this morning.
