Zcash Plans to Activate NU7 on November 5, Sprout Pool ZEC Will Become Unspendable

Odaily reports: Privacy blockchain project Zcash plans to implement the NU7 upgrade, after which it will stop accepting the fourth version transaction format that allows spending of Sprout pool funds. If ZEC is not transferred out before the upgrade, holders may lose the ability to spend the related funds.The proposal will not destroy Sprout pool funds, and access may still be restored in the future. However, the proposal warns that funds remaining in the pool may also become permanently unspendable. Zcash co-founder Zooko Wilcox has reposted the related reminder.NU7 is scheduled to activate on the testnet on October 6, and Zcash is expected to decide on October 20 whether to activate on the mainnet on November 5 as planned. The upgrade will also shorten the target block time from 75 seconds to 25 seconds and maintain the network's halving cycle. (Cointelegraph)

Dragonfly Partner: Zcash Vulnerability Incident Overhyped by Market, Majority of Holders Unaffected

Haseeb, Managing Partner at Dragonfly, has addressed the recently patched Zcash vulnerability, stating that there are many misconceptions in the market regarding the incident. He pointed out that even if the vulnerability had been exploited before the fix, an attacker could only profit by forging ZEC within the shielded pool. For these tokens to enter mainstream trading platforms, they would first need to be converted from shielded addresses to transparent addresses. Since the supply of ZEC in transparent addresses is publicly verifiable, any abnormal transfers exceeding the maximum supply would be detected and blocked. Therefore, the vast majority of investors and exchange users holding transparent ZEC would not be affected.Haseeb stated that the Zcash team plans to introduce a new “Turnstile” mechanism and a new shielded pool in future upgrades to verify that the current shielded pool does not suffer from inflation issues. He also noted that formally verified cryptographic systems can reduce implementation errors at the design level. Finally, Haseeb disclosed that Dragonfly still holds ZEC, and he is personally an investor in ZODL.
