[Zcash to Activate NU7 on November 5, Sprout Pool ZEC Will Become Unspendable] Odaily Planet Daily News: The privacy blockchain project Zcash plans to implement the NU7 upgrade, which will stop accepting the fourth version of transaction formats that allow spending from the Sprout pool. If ZEC is not transferred out before the upgrade, holders may lose the ability to spend the associated funds. This proposal will not destroy the funds in the Sprout pool, and access may be restored in the future. However, the proposal warns that funds left in the pool could also become permanently unspendable. Zcash co-founder Zooko Wilcox has shared a related reminder. NU7 is scheduled to activate on the testnet on October 6, and Zcash is expected to decide on October 20 whether to proceed with activation on the mainnet as planned on November 5. The upgrade will also reduce the target block time from 75 seconds to 25 seconds while maintaining the network halving cycle. (Cointelegraph)
