The privacy blockchain project Zcash plans to implement NU7 upgrade, and after the upgrade, it will no longer accept the fourth version of transaction format that can be used to spend Sprout pool funds. Failure to transfer ZEC before the upgrade may result in inability to spend. NU7 is scheduled to be activated on the test network on October 6th, and Zcash is expected to decide whether to activate on the main network on November 5th on October 20th. The upgrade will shorten the target block time from 75 seconds to 25 seconds and maintain the network halving cycle. Zcash co-founder Zooko Wilcox has forwarded the relevant reminder.
