Crypto News
Zcash has activated its NU7 protocol upgrade on testnet, where it is testing a target block interval of 25 seconds, down from 75 seconds. The upgrade also disables version 4 transactions and introduces new fee rules.
Why it matters
NU7 puts changes to Zcash’s block timing and transaction rules through live testing before any mainnet deployment. The shorter target interval is a substantial change to the network’s intended cadence, but the testnet activation alone does not establish when or whether the changes will reach mainnet.
Market impact
The development is a protocol test, not a confirmed change to ZEC’s live network. Traders and users will be watching for further details on testnet results and any decisions about a mainnet rollout.
