Zcash Halving Countdown
Track the countdown to the next Zcash halving, with estimated timing, remaining blocks, and the scheduled reduction in ZEC block rewards.
COUNTDOWN TO THE
NEXT ZCASH HALVING
Monitor remaining blocks and the reward schedule behind Zcash’s next supply milestone.
Estimated date & time: 26 November 2028, 15:38 UTC.
The total Zcash block subsidy will decrease from 1.5625 ZEC to 0.78125 ZEC.
Next halving will be at block 4,406,000
What Is the Zcash Halving?
The next Zcash halving will take place at block 4,406,400. At that point, the total Zcash block subsidy will fall from 1.5625 ZEC to 0.78125 ZEC per block.
The countdown above estimates the date and time from the current Zcash block height and its target interval of approximately 75 seconds per block.
The exact date may move forward or backward because the halving is activated by a specific block height—not by a fixed calendar date. Individual blocks can arrive faster or slower than the target interval, so the estimate becomes more accurate as block 4,406,400 approaches.
How Does the Zcash Halving Work?
Zcash miners use computing equipment to process transactions, produce blocks and secure the network through Proof of Work.
Each valid block creates a predetermined amount of new ZEC known as the block subsidy. The subsidy is separate from the transaction fees included in the block.
Zcash’s total block subsidy is reduced by 50% approximately every four years. This limits the rate of new ZEC issuance and allows the total supply to approach its maximum of 21 million ZEC.
The total block subsidy is not necessarily identical to the amount received directly by the miner. Zcash funding-stream rules may allocate part of the subsidy to approved recipients or protocol funding mechanisms. The active allocations are defined separately from the halving itself.
Zcash Halving History
| Event | Block | Date | New Total Block Subsidy |
|---|---|---|---|
| Zcash launch | 0 | 28 October 2016 | Slow-start period |
| Full initial subsidy | 20,000 | November 2016 | 12.5 ZEC |
| Blossom spacing adjustment | 653,600 | 11 December 2019 | 6.25 ZEC |
| First halving | 1,046,400 | 18 November 2020 | 3.125 ZEC |
| Second halving | 2,726,400 | 23 November 2024 | 1.5625 ZEC |
| Third halving | 4,406,400 | Estimated November 2028 | 0.78125 ZEC |
| Fourth halving | 6,086,400 | Future estimate | 0.390625 ZEC |
What Happens When All Zcash Has Been Mined?
Zcash’s block subsidy will continue to decrease through future halvings. Each event will reduce the remaining subsidy by 50%.
Over many decades, the total supply will approach its maximum of 21 million ZEC. Once the subsidy becomes too small to create another zatoshi, the smallest unit of ZEC, new issuance will effectively stop.
At that stage, miners would be expected to depend primarily on transaction fees or any other incentives permitted by the future Zcash protocol.
This transition will happen gradually over many halving cycles rather than immediately after the 2028 event.
