What happened

Coinholders voted to keep Bitcoin-style halvings. Separately, the NU7 upgrade now targets a November mainnet activation after an October 6 testnet activation, with 25-second blocks planned. These are reported decisions and targets; the record does not show that the upgrade has been activated.

Paradigm co-founder Matt Huang disclosed a ZEC investment. The upstream record also reports that ZEC gained roughly 20% over 24 hours. It gives no investment size or transaction date, and it does not establish that the disclosure caused the price move.

Why it matters

The vote clarifies the coinholders’ stated preference on halvings, while NU7 gives observers a dated protocol milestone and a specific block-time target to check. The investment disclosure adds a separate capital signal. Together, they make this a useful moment to examine Zcash’s protocol plans and interest in ZEC, without treating market attention as proof of adoption or upgrade success.

What to watch

Watch for confirmation of the October 6 testnet activation, evidence that the planned 25-second blocks work as intended, and a confirmed November mainnet activation.
