Zcash NU7 Upgrade Could Leave Sprout Funds Unspendable Around Nov. 5
Zcash (ZEC) holders with funds in the Sprout privacy pool must move them by around Nov. 5, as the NU7 upgrade is expected to disable the transaction type required for Sprout. Balances left in Sprout may remain on the network but will be unspendable. Sprout holders can transfer funds to the Sapling pool. The NU7 upgrade also shortens the usual preparation time for node operators.
