ZEC Zcash 在测试网激活 NU7 升级，ZEC 瞄准 1505 美元但面临 1100 美元支撑位风险
专注于隐私保护的区块链 Zcash 以其屏蔽交易功能而闻名。周一，其原生代币 ZEC 在经历周末低点 1254 美元的技术性反弹后，在 1330 美元附近盘整。此次复苏紧随项目团队宣布已在公共测试网上激活备受期待的 NU7 网络升级，使得该升级的功能更接近预期于 11 月初在主网上部署的目标。
NU7 升级在测试网推出
10 月 4 日，Zcash 测试网浏览器 ZecBlock 显示，指定的激活区块 4,465,026 于 UTC 时间 18:21:45 被挖掘。随后，Zcash 团队通过 X（原 Twitter）确认 NU7 已在测试网络上上线。
此次激活引入了一个重要的测试期，允许开发人员和生态系统运营商在受控环境中评估新规则。目前主网部署的目标日期仍为 11 月 5 日，最终的实际激活高度决定将于 10 月 20 日确定。
在此期间，该项目将收集反馈和运营数据，以确保在实时网络上最终确定任何更改之前升级的稳定性。
更快的区块、新的费用机制和交易变更
NU7 的首要功能是将其目标区块间隔从 75 秒缩短至 25 秒。由于 Zcash 上的区块是用户交易的批次，这一调整旨在提高交易确认速度并增强网络响应能力。
Although the new range is set to one-third of the existing standard, block creation time may still fluctuate due to factors such as network conditions and mining luck. This testnet phase is designed to help network operators observe the effects of faster block production before similar changes are introduced to real-time networks.
With the activation of NU7, developers and infrastructure operators have a time window to evaluate upgrade performance, especially before planned mainnet deployments, focusing on monitoring faster block intervals and how new fee mechanisms affect transaction processing and mining rewards.
NU7 also brings the "Network Sustainability Mechanism", which redistributes some transaction fees and converts some of the immediate payments into future block rewards for distribution, rather than immediately rewarding all fees to miners.
This shift creates an incentive mechanism designed to maintain the network's long-term operations and introduces broader changes beyond just reducing block time.
Mini Dictionary: Network Sustainability Mechanism
A feature designed to reallocate part of transaction fees to future mining rewards to support long-term operations of the network.
Another significant change within NU7 is the disabling of version 4 (v4) transactions, which affects the funds still retained in the Sprout pool, Zcash's original shielded address protocol. Once NU7 is activated on the main network, any ZECs retained in Sprout addresses will become unexpendable unless users take advance action to transfer funds.
Affected holders need to carefully distinguish the schedules of the test net and the main net, as restrictions will only take effect after the main net is upgraded. The final activation height chosen will determine when these rules take effect on the real-time blockchain.
ZEC Price Outlook: Focus on both sides
On the technical side, although the ZEC/USD daily chart shows signs of recovery after recently breaking through US$1300, it still sends a cautious signal. The Relative Strength Index (RSI) remains at 58, indicating that bullish momentum exists and that the MACD is in positive territory.
If this upward trend is maintained, ZEC may target the induced liquidity (ILQ) level of US$1505 as the next major resistance level. Amid a broader rally, prices could return to recent highs of $1701 within days.
However, a reversal in sentiment could push ZEC back to support at $1254. If this level cannot be held, the next psychological support level is set at around $1100, emphasizing the coin's vulnerability should bear market forces intensify.
ZEC's position near US$1330 depends on whether buyers can maintain the recovery momentum or sellers will push prices into the US$1100 support area.
