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.

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.
