Update
Zcash Upgrade Set for November
Zcash developers have settled on the exact block height (3,543,405) for the NU7 upgrade, which will triple the payment speed by reducing the time between blocks from 75 seconds to 25 seconds. The upgrade has been running on the test network since early October and is scheduled to activate on November 5. The NU7 upgrade also removes 60% of the fees collected in each block and will shut down Sprout, Zcash's original privacy system, starting from the activation date.
