TronWeekly's opening line says NU7 brings 'longer block times,' while CoinTurk News EN, TheNewsCrypto and CryptoNewsZ all report the opposite — a cut from 75 to 25 seconds.
TronWeekly's opening line says NU7 brings 'longer block times,' while CoinTurk News EN, TheNewsCrypto and CryptoNewsZ all report the opposite — a cut from 75 to 25 seconds.
What all sources agree on
NU7 activated on the public testnet at block 4,465,026, mined at 18:21:45 UTC on October 4.
The current target for mainnet deployment is November 5, pending a final decision on October 20.
NU7 introduces a Network Sustainability Mechanism that redirects a portion of transaction fees toward future block rewards rather than paying all fees immediately to miners.
NU7 invalidates version 4 transactions, which affects funds held in the Sprout pool; holders must move Sprout funds before mainnet activation or they become unspendable.
The 21 million ZEC supply cap and issuance schedule remain unchanged under NU7.
Where the reports disagree
1Whether NU7 lengthens or shortens Zcash's block time
The upgrade launched with the activation of block 4,465,026 on October 4th and marks significant changes to Zcash’s network, including longer block times and a new system for distributing transaction fees.

NU7’s headline feature is reducing the target block interval from 75 seconds to 25 seconds.
CoinTurk News EN 2026-10-05 10:57
NU7 reduces Zcash’s target block time from 75 seconds to 25 seconds.
TheNewsCrypto 2026-10-05 12:18
The biggest change in NU7 is the plan to cut Zcash’s block interval from 75 seconds to 25 seconds.
CryptoNewsZ 2026-10-05 12:11
What would settle it: The Zcash Foundation's NU7 specification or the testnet explorer ZecBlock's recorded block interval data.
What to make of it
Treat the testnet activation block, the November 5 mainnet target, the October 20 decision date, and the fee-sharing and Sprout-pool changes as established across all reports. TronWeekly's own intro line describing 'longer block times' conflicts with its own later text and with every other outlet's account of a cut from 75 to 25 seconds, so that specific phrase should not be relied on.
