Zcash is targeting a November upgrade intended to make private payments up to three times faster, according to a report from CoinDesk: Bitcoin, Ethereum, Crypto News and Price Data.
The upgrade, referred to as NU7, would reduce block times to 25 seconds and set aside at least 60% of transaction fees to supplement mining rewards beginning in 2031. The changes are designed to improve transaction efficiency while adjusting how network participants are compensated.
Key Facts
- Zcash is targeting a November upgrade called NU7.
- The upgrade aims to make private payments up to three times faster.
- Block times would be reduced to 25 seconds.
- At least 60% of transaction fees would be set aside for mining rewards starting in 2031.
What Does the Zcash Upgrade Change?
The primary goal of NU7 is to reduce the time it takes to confirm private payments. By lowering block times from their current pace to 25 seconds, transactions using Zcash's shielded functionality could see faster processing. This addresses a longtime criticism of privacy-focused blockchains: that privacy comes at the cost of performance.
Reducing block times helps ensure that users do not have to wait as long for confirmations, especially during periods of higher activity. It also positions Zcash to better compete with other cryptocurrencies that have adopted faster settlement mechanisms.
How Would Mining Rewards Be Affected?
Beyond speed improvements, NU7 includes a shift in how transaction fees are distributed. The proposal would allocate at least 60% of collected fees toward supplementing mining rewards, with this mechanism set to begin in 2031. This long-term incentive structure aims to sustain network security as block subsidies decline.
The change reflects broader trends in blockchain economics, where networks are increasingly relying on fee-based incentives to keep validators or miners engaged once new coin issuance slows. Setting aside a portion of fees rather than burning them or sending them entirely to miners introduces a hybrid model that could support both security and development funding.

Zcash is one of several major cryptocurrencies pursuing upgrades to enhance usability and performance, particularly in the area of private transactions. See our trading-crypto section for ongoing coverage of z cash upgrade developments and similar network updates across the industry.
Why It Matters
Performance remains a key barrier to adoption for privacy-centric cryptocurrencies. Faster private payments could make Zcash more attractive to users who prioritize both confidentiality and speed, potentially expanding its role in everyday transactions and institutional use cases.
Adjusting mining incentives also signals a strategic move to maintain long-term network health, aligning Zcash with evolving economic models seen in other proof-of-work ecosystems.
What To Watch
Community feedback and formal governance approvals will determine whether NU7 proceeds as scheduled. Further details on technical specifications and rollout plans may emerge in upcoming developer calls or foundation communications.
Zcash's NU7 aims to triple private payment speeds through 25-second block times while redirecting 60% of fees to miners starting in 2031.
