Key Developments & Data
Zcash has activated the NU7 upgrade on its public testnet at block 4,465,026, dropping targeted wait times from 75 seconds to 25 seconds.
The network will now divert 60% of transaction fees into a reserve intended to fund future mining rewards, leaving active miners with 40%.
Faster blocks will not triple new coin creation, as the scheduled reward per block automatically falls to one-third to maintain the original issuance schedule.
The upgrade disables transactions used by Sprout, Zcash’s oldest private-payment system, requiring holders to move those funds before mainnet activation.
Developers will review test results on Oct. 20, aiming for a targeted mainnet rollout on Nov. 5.

Zubiqo Strategic Assessment
Primary Impact
Crypto exchanges and merchants processing Zcash will see confirmation wait times drop by nearly 70%.
Strategic Shift
Proof-of-Work privacy networks are fundamentally restructuring their fee economics to build long-term security reserves as block subsidies naturally decline.
The Ripple Effect
Miners will face immediate short-term revenue pressure from the 60% fee diversion, potentially shaking up the Zcash mining distribution before the November mainnet launch.
