Zcash NU7 Upgrade Begins Testing 25-Second Block Times on Testnet

October 5, 2026, 10:55 AM UTC (2 hours ago) · 1 source · Summarized by CryptoBipto

The Zcash network's NU7 upgrade is being tested on a testnet with a target of reducing block times to 25 seconds. This would represent a significant change from the current block time, aiming to improve transaction speed on the privacy-focused blockchain.

WHY IT MATTERS

A blockchain's "block time" is how often a new batch of transactions gets confirmed and added to the chain — think of it like how frequently a bus departs from a station. Shorter block times mean transactions can be confirmed faster, similar to buses leaving more often so passengers wait less. Zcash is a cryptocurrency focused on privacy, and this upgrade is being tested in a "testnet," which is like a practice version of the network where developers can try out changes without risking real funds. If the upgrade eventually goes live, it could change how quickly Zcash users see their transactions confirmed.

Zcash, a cryptocurrency known for its privacy features, is working on its NU7 network upgrade, which is currently being tested on a testnet environment.
