Zcash Lost More Than Half Its Value Due to Critical Vulnerability: What's Known
The anonymous cryptocurrency Zcash (ZEC) has suffered a precipitous decline, losing more than half its value in 24 hours. On Friday morning, June 5, the asset's price currently fell to $272, down from $602 on the morning of June 4, according to CoinMarketCap data.The panic sell-off began after Shielded Labs, an organization developing the Zcash ecosystem, announced the discovery of a critical bug in the Orchard transaction pool.
At the time of writing, the asset's price is $367.It's worth noting that Zcash is a decentralized, open-source cryptocurrency whose primary goal is to guarantee users absolute anonymity and privacy of their money transfers.

Security analysts discovered that, due to lax restrictions in the Orchard pool architecture, attackers were able to create counterfeit ZEC tokens without any control. The technical flaw allowed arbitrary input into an elliptic curve multiplication operation, with the system successfully processing such transactions rather than blocking them.
This bug has existed in the code since May 2022. Because the Orchard pool is completely confidential, Shielded Labs admits that it is currently impossible to determine with certainty whether anyone has exploited this exploit in the past three years. At the same time, the developers hope that a mass production of counterfeit coins did not occur, as the market would have reacted to such an oversupply much sooner.To address the threat, the Zcash team temporarily suspended the Orchard pool on the night of Tuesday, June 2nd. Following this, an emergency network upgrade was activated due to a hard fork, halting the generation of new blocks on the blockchain for several hours.
The developers are currently preparing a large-scale technical solution. To stabilize the situation, they plan to implement the following:
A dedicated tool allowing any user to independently verify the absence of counterfeit tokens on Orchard;
A new, fully secure pool;
A turnstile accounting system that will track the movement of funds and eliminate the possibility of asset duplication. #newscrypto Investors are dumping the asset
After widespread panic erupted in the market, major players began urgently closing their ZEC positions. Specifically, Arthur Hayes, co-founder of the BitMEX crypto exchange and founder of the Maelstrom fund, announced a complete sell-off of his ZEC holdings. He stated in an interview that he would not tolerate the risk of a potential exploit on this blockchain. #NewsAboutCrypto
