NU7 for $ZEC is already running on the testnet, with the mainnet target on November 5.
One-sentence version: Block production is 3x faster, and the old Sprout pool is about to close.
1️⃣ Testnet activation height is 4,465,026. Block produced on October 4 at 18:21 UTC. Zcash official X confirmed that NU7 testnet is live. Zebra 7.0.0-rc.0 from the Zcash Foundation is a candidate version, specifically for node real-world testing.
2️⃣ Target block interval: 75 seconds → 25 seconds (ZIP 218). The average time to confirm the first transaction is also reduced to around 25 seconds.
3️⃣ Disable v4 transactions. Sprout transfers can only go through v4, so after mainnet activation, any ZEC sitting in the Sprout pool (old addresses starting with “zc”) cannot be spent directly.
4️⃣ New “Network Sustainability Mechanism” (NSM): 60% of each block’s transaction fees go into reserve, while miners keep 40%. After reserves accumulate, the smaller portions flow back into block rewards; the halving schedule remains unchanged.
5️⃣ On October 20, developers reviewed the testnet performance and decided whether to launch the mainnet and set the activation height. The mainnet height is still TBD for now.
My take:
The most practical information this time isn’t “3x faster”—it’s the Sprout part. If you dig out an old wallet from years ago and the money is still sitting at a zc address, don’t wait until November to remember it. At that point, it won’t just be a migration issue.
Exchanges and wallets also need to upgrade. Confirmation counts and deposit/withdrawal rules may change—then just watch each provider’s announcements.
Testnet ≠ mainnet. The official timeline even labels it “tentative,” so don’t brainlessly assume it’s “already decided.”
