Zcash Sets November 5 Target to Make Private Payments Three Times Faster

What Zcash's Seventh Network Upgrade Includes

Zcash is a cryptocurrency that uses zero-knowledge proofs to let people send payments privately. Transactions are written into blocks by miners, and those blocks form the Zcash chain. Network Upgrade 7, called NU7, is a coordinated package of software changes targeting block timing, transaction formats, and how miners collect fees. Zcash structures all protocol changes through published Zcash Improvement Proposals, or ZIPs, each of which goes through public review before adoption.

The target activation date is November 5, 2026, but as of September 18 developers had not yet set the final mainnet block height. Zcash's plan calls for public testnet observation beginning October 6, followed by an October 20 meeting to confirm the activation block. Developer Sean Bowe has spoken publicly about the November timeline. If the testnet reveals critical issues, the activation block can shift to a later height without canceling the upgrade.

Five builder organizations agreed on the NU7 scope: the Zcash Foundation, Project Tachyon, Valar Group, ZODL, and Shielded Labs. Coverage sometimes describes this as "unanimous agreement," which is accurate within that group of five software teams. Broader stakeholder input flows through ZEC-weighted on-chain voting, where coin holders vote directly on specific proposals. Both layers of approval — technical sign-off and community vote — are part of how Zcash governs protocol changes.

• ZIP-218: reduces target block spacing from 75 seconds to 25 seconds
• ZIP-230: introduces a version 6 transaction format
• ZIP-231: adds memo bundle support to transactions
• ZIP-235: creates a fee-banking mechanism to supplement future mining rewards
• Deactivates version 4 transactions across the network

From 75 Seconds to 25 — What the Block Time Cut Means

ZIP-218 is the technical foundation of the three-times-faster claim. Right now, Zcash targets a new block every 75 seconds. After NU7, that target drops to 25 seconds. The math is direct: 75 divided by 25 equals 3. A user sending a shielded Zcash transaction would wait roughly one-third as long to see that first confirmation appear in their wallet after the upgrade activates.

The speedup applies specifically to confirmation latency — the time between broadcasting a transaction and seeing it included in a block. It does not change how long a device takes to generate the zero-knowledge proof before the transaction is even broadcast. That proof generation time depends on device hardware and circuit design. For most users, however, confirmation wait is the visible delay they notice, so the practical experience of sending a private payment improves meaningfully.

Faster blocks also mean roughly three times as many blocks per day — about 3,456 instead of 1,152. Each block therefore carries a smaller slice of daily transaction volume, which affects the per-block fee pool. Zcash's community voted separately to preserve the existing halving schedule even as block spacing shrank, with 98.9% of votes cast in favor. That choice keeps the economic calendar intact for the miners and holders who planned around it.

How the Fee Bank Accumulates and Pays Out

ZIP-235 introduces a reserve mechanism built into the block-validation rules. When a miner seals a block, the protocol calculates total transaction fees collected and withholds at least 60 percent using the formula floor(fees × 6 ÷ 10). Any fractional remainder rounds in the miner's favor. These withheld fees do not disappear — they accumulate in a protocol-level reserve from the moment NU7 activates, scheduled for November 2026.

The reserve begins paying out in February 2031. That date was set through on-chain governance, where ZEC holders voted on the reissuance schedule with high turnout and near-unanimous approval. The payout supplements miner block rewards at a point when Zcash's subsidy schedule will have fallen significantly, giving miners additional income during the lower-subsidy years of the 2030s and helping keep the network economically viable.

The design echoes Ethereum's EIP-1559, which redirects a portion of transaction fees away from block producers. The key difference is permanence: Ethereum's mechanism burns those fees forever, while Zcash's ZIP-235 returns them to miners after the banking period ends. From NU7 activation through January 2031, miners collect roughly 40 percent of transaction fees per block. The remaining 60 percent builds in reserve for the February 2031 payout cycle.

Near-Unanimous Votes and What They Approved

Zcash uses on-chain governance for major protocol decisions. ZEC holders lock coins to vote on specific proposals, with each vote weighted by the amount locked. The ZIP-235 fee-banking mechanism passed with 96.6% approval. More than 2.4 million ZEC participated, representing about 66% of the ZEC eligible to vote — a strong turnout by cryptocurrency governance standards. The February 2031 reissuance start date was part of what voters approved.

A companion vote addressed whether to keep Zcash's halving schedule unchanged as blocks speed up. With 98.9% approval, voters chose to preserve the existing schedule. The halving cuts block rewards in half roughly every four years, and aligning that event with NU7's faster block rate required a deliberate technical adjustment. Community consensus was clear: the economic milestone should arrive when miners and holders had historically expected it.

The formal community vote is separate from the builder-team sign-off described in the first section. The five builder organizations coordinate the code and define the upgrade scope. The ZEC holder community votes on the economics and key dates. Together, these two layers give an upgrade both technical readiness and stakeholder legitimacy before any activation block height is confirmed on mainnet — a governance model Zcash has refined across each previous numbered upgrade.

How November 5 Delivers Faster Private Payments

If the October 6 testnet run shows no critical issues and developers confirm the activation height on October 20, NU7 goes live around November 5, 2026. At that block, every Zcash full node transitions simultaneously. Wallets that support shielded transactions will start receiving first confirmations in roughly 25 seconds instead of the current 75, making private payments noticeably faster without requiring any action from ordinary users.

Exchanges and payment processors that accept Zcash may lower their required confirmation counts or reduce customer wait times, since each confirmation now arrives faster. Platforms watching live crypto markets will see the Zcash mempool clear at three times its current rate after activation. Node operators need only run the updated client software before the cutover block; no wallet migration or manual action is required from regular users.

NU7 bundles two distinct improvements into one activation event: faster confirmations for users today, and a fee reserve built for miners in the 2030s. Whether both goals are achieved depends on clean testnet results this October and on continued adoption of shielded payments by wallets and exchanges. The November 5 target date is the first checkpoint — developers confirm or adjust it after watching the test network for three weeks.
