Zcash Activates NU7 Network Upgrade on Testnet Ahead of Mainnet Launch
- The NU7 network upgrade was activated on Zcash’s testnet on Oct. 4, with block number 4,465,026 mined at 18:21 UTC.
- NU7 aims to reduce the network’s target block spacing from 75 seconds to 25 seconds.
- The upgrade will disable version 4 transactions, affecting funds in Zcash’s legacy Sprout shielded pool.
- A Network Sustainability Mechanism will redirect part of transaction fees into future block rewards.
- Developers will decide on mainnet activation and set its height on Oct. 20, with a targeted launch date of Nov. 5.
The testnet phase allows developers to evaluate the NU7 upgrade under real conditions before proceeding to mainnet activation. This upgrade is significant as it introduces changes that could enhance network efficiency and sustainability.
With the goal of reducing block spacing from 75 seconds to just 25 seconds, Zcash is moving forward with its NU7 upgrade, confirming its activation on testnet ahead of the planned mainnet rollout in November.
