Zcash holders have voted to shorten block times to 25 seconds and push back the Network Sustainability Mechanism until 2031, showing a clear preference for quicker transactions without immediate changes to fee rewards.
Zcash's next protocol upgrade is moving ahead with a major change: token holders have voted to cut the network's block time from 75 seconds to 25 seconds. This means users should see their transactions confirmed more quickly. The same vote also showed strong support for keeping the current issuance structure, delaying a planned fee-recycling mechanism until 2031.
Block time changes
Roughly 2.4 million ZEC-about two-thirds of eligible voting supply-supported both the faster block time and the retention of the current halving schedule.
Developers now have a tight deadline. Any features not ready by September 30 will be left out of the upcoming NU7 upgrade. The final list of changes is expected by that date, but there's no confirmed timeline for testnet or mainnet activation. The coinholder poll was separate from advisory group surveys, which showed a closer split on the halving issue.
Fee recycling postponed
The Network Sustainability Mechanism (NSM) was the other main topic. Originally planned for 2026, NSM would recycle 60% of ZEC transaction fees back into future block rewards to help address concerns about declining miner incentives as block rewards shrink. Nearly 97% of voting ZEC chose to delay this mechanism until February 2031, with only about 70,239 ZEC supporting immediate implementation. The total ZEC supply cap of 21 million remains unchanged. The delay shows a preference for stability over experimenting with fee-based rewards.
The technical foundation for the block time reduction is ZIP 218, which ensures that daily ZEC issuance remains stable by proportionally lowering the per-block reward. This approach allows for faster confirmations without increasing inflation, maintaining the integrity of Zcash's monetary policy.
Market reaction and next steps
After the poll results were published, ZEC's price rose 3.8% over the next 24 hours, extending a 132% rally over the previous month, according to CoinMarketCap. There's still no set date for the upgrade, but the market's response suggests investors are paying close attention to protocol governance. The final scope of the NU7 upgrade will depend on what developers can finish by September 30; anything not ready will be left out for now.
The coinholder poll used spendable ZEC in the Ironwood shielded pool at the time of the snapshot to determine voting power. Among the Zcash Community Advisory Panel, opinions were more divided, with a near-even split between those preferring a gradual issuance curve and those supporting the current halving schedule. In the end, the coinholder vote decides, and the network's monetary policy will stay the same until at least 2031.
This round of governance shows that the Zcash community values predictability and gradual change over rapid experimentation. The strong support for faster blocks, along with reluctance to change fee distribution or supply dynamics in the near term, suggests that users and holders are prioritizing transaction speed and network stability. As other blockchains debate tokenomics reforms, Zcash's approach stands out for its caution and clarity.
Block time is a key setting in any blockchain, affecting how quickly transactions are confirmed and how often new coins are issued. Shorter block times can improve user experience by reducing wait times, but they also mean more frequent block rewards and require careful adjustment to avoid inflating the token supply. Mechanisms like the Network Sustainability Mechanism are meant to address the long-term challenge of declining block rewards, which can eventually reduce miner participation and threaten network security if not offset by transaction fees or other incentives. The Zcash community's decision to delay NSM reflects a broader debate in crypto about how to balance immediate user needs with the long-term sustainability of decentralized networks.
