Zcash NU7 Upgrade Requires Zebra 7.0.0 Before Nov. 5

The Zcash Foundation has released Zebra 7.0.0, the node software required for Zcash’s NU7 mainnet upgrade. Operators must upgrade before block 3,543,405, expected around Nov. 5, to remain on the network’s consensus chain; Zebra 6.4.x is expected to stop operating around Nov. 2. The release also improves syncing near the chain tip and addresses security advisories, though the summaries differ on the number fixed: one reports five and the other seven. NU7 cuts Zcash’s target block time from 75 seconds to 25 seconds without changing scheduled daily ZEC issuance, the four-year halving schedule or the 21 million ZEC supply cap. Under its Network Sustainability Mechanism, 60% of transaction fees will be reserved for potential future mining rewards, while miners receive 40%. Reserve-funded rewards are scheduled to begin at block 8,939,664, expected around February 2031. NU7 changes protocol compatibility and disables version 4 transactions. Holders with funds in the Sprout pool must move them before activation to retain the ability to spend them afterward. Zebra 7.0.0 also migrates the node database automatically; reverting to Zebra 6.x requires a full resync. Faster blocks may reduce payment and exchange-deposit waiting times, but the upgrade does not alter scheduled issuance or directly signal a ZEC price move. The Foundation has not said how many operators still need to upgrade.

The upgrade is important for Zcash network operations, but its direct price implications are limited. Faster target blocks and improvements to node syncing may support usability and network reliability, while the unchanged daily issuance and 21 million ZEC cap provide no immediate change to token supply. Reserving 60% of transaction fees for possible future rewards could shape long-term miner incentives, but those rewards are not scheduled to start until around 2031. In the short term, traders may watch the activation deadline, operator readiness and any disruption caused by incompatible nodes or Sprout funds that were not moved. Such technical events can create temporary volatility, but the summaries provide no evidence of a direct catalyst for sustained ZEC price movement. Longer term, successful activation could strengthen confidence in network development; the upgrade alone does not establish a bullish or bearish price trend.
