Zcash‘s second halving, which occurred on November 23, 2024, at block height 2,726,400, cut the block reward from 3.125 $ZEC to 1.5625 $ZEC. For miners, that meant an immediate 50% drop in $ZEC earned per block. For the broader market, it reduced the rate at which new $ZEC enters circulation, tightening supply in a network that mirrors Bitcoin‘s hard cap of 21 million coins. As of June 19, 2026, $ZEC trades in the range of $448 to $481, with roughly 16.7 million $ZEC in circulation out of a maximum supply of 21 million.
How Does the Zcash Halving Work?
Zcash launched in October 2016 as a fork of the Bitcoin codebase, inheriting its core monetary structure along with one major addition: the ability to send fully private transactions using zero-knowledge proofs called zk-SNARKs (Zero-Knowledge Succinct Non-Interactive Arguments of Knowledge). In simple terms, a zk-SNARK lets the network confirm a transaction is valid without revealing who sent it, who received it, or how much was transferred.
Like Bitcoin, Zcash caps its total supply at 21 million coins and reduces its block reward by 50% approximately every four years. Each halving occurs at intervals of 1,680,000 blocks, with blocks produced roughly every 75 seconds. Here is the full reward history:
- October 2016 (launch): 12.5 $ZEC per block, with a block time of 150 seconds
- December 2019 (Blossom upgrade, block 653,600): Block time was halved from 150 seconds to 75 seconds, and the block reward was simultaneously halved from 12.5 $ZEC to 6.25 $ZEC to keep daily issuance constant. This is not counted as an official halving.
- November 18, 2020 (first halving, block 1,046,400): Reward dropped from 6.25 $ZEC to 3.125 $ZEC. This coincided with the Canopy network upgrade, which also ended the original Founders Reward.
- November 23, 2024 (second halving, block 2,726,400): Reward dropped from 3.125 $ZEC to 1.5625 $ZEC per block.
- Late 2028 (third halving, expected, block 4,406,400): Reward will drop to 0.78125 $ZEC per block.
The current block reward of 1.5625 $ZEC is not paid entirely to miners. Since the NU6 network upgrade in November 2024, the reward is split three ways: 80% goes to miners (1.25 $ZEC per block), 8% goes to the Zcash Community Grants Committee (ZCG), which funds ecosystem development, and the remaining 12% goes into a protocol-tracked “lockbox” held for future community governance decisions.
What Happened to Miner Revenue After the 2024 Halving?
The immediate effect of any halving is as follows: miners earn half as many coins per block as they did the day before. Whether that translates into lower dollar revenue depends entirely on whether the $ZEC price rises fast enough to compensate.
After the 2024 halving, Zcash miners initially faced compressed margins. The network uses the Equihash proof-of-work (PoW) algorithm, which requires specialized ASIC (application-specific integrated circuit) hardware. Consumer GPU mining is no longer competitive at current difficulty levels. The leading hardware, such as the Bitmain Antminer Z15 Pro, costs roughly $2,500 upfront and becomes profitable only when electricity rates sit below approximately $0.06 to $0.07 per kilowatt-hour. Industrial-scale miners paying $0.04 to $0.05 per kilowatt-hour have a significant cost advantage.
The price action following the halving provided some relief. Measured from the end of 2024 to the end of 2025, $ZEC gained approximately 92% year-on-year, driven partly by scarcity expectations and partly by broader crypto market conditions. Peak gains during the same period were considerably higher, with $ZEC hitting $589 at its 2025 high. The 2020 halving produced an even larger sustained move, with $ZEC surging over 500% in the months that followed, though neither past outcome guarantees future results.
What makes Zcash’s mining economics distinct from Bitcoin’s is the addition of a Crosslink hybrid PoW plus proof-of-stake (PoS) finality mechanism currently in development. A partial shift toward PoS began taking shape in late 2025, which is expected to change how block confirmation works without immediately eliminating PoW mining. The full transition remains subject to community approval.
How Does the Halving Shape Zcash’s Long-Term Supply?
At launch in 2016, Zcash issued 12.5 $ZEC per block on a 150-second block schedule. After the Blossom upgrade in December 2019 cut the block time to 75 seconds, the per-block reward was also halved to 6.25 $ZEC, keeping daily issuance roughly constant. Each official halving since then has cut that per-block rate in half again, meaning the total supply approaches 21 million more slowly after each event.
As of June 2026, approximately 16.7 million $ZEC are in circulation, representing about 79.5% of the maximum supply. The remaining 4.3 million $ZEC will be released over many decades of continued mining, with each successive halving slowing that issuance rate further. The final $ZEC will not be mined for many years.
What this means in practical terms:
- New supply entering the market each day is lower than at any point in Zcash’s history since launch
- Each halving increases the stock-to-flow ratio, a measure that compares existing supply to annual new issuance
- Lower daily issuance reduces constant sell pressure from miners liquidating rewards to cover electricity costs
One notable feature of Zcash’s supply picture is the shielded pool. Approximately 30% of circulating $ZEC is held in shielded addresses, meaning those coins are not visible in public transaction history. The Zashi wallet, developed by the Electric Coin Company (ECC), now defaults to shielded transactions, encouraging more users to move $ZEC into the private pool. As the shielded supply grows, it effectively reduces the portion of $ZEC that is liquid and tradeable on transparent markets.
Does the Halving Strengthen Zcash’s Scarcity Narrative?
The comparison to Bitcoin is deliberate and built into Zcash’s design. Both assets share a 21 million hard cap and a halving schedule. The key difference is that Zcash adds optional privacy through shielded addresses and transparent addresses, giving users a choice between visibility and confidentiality.
The scarcity model functions the same way. Supply issuance slows on a predictable schedule, and that schedule is enforced by the protocol rather than any central authority. Historically, the reduction in new supply has coincided with price increases, though the timing, scale, and duration of those moves have varied.
For miners specifically, the scarcity narrative works in two directions. On one hand, rising prices after a halving can offset the cut in block rewards. On the other hand, if prices do not rise quickly enough and difficulty remains elevated as more ASICs come online, smaller or less efficient operations face the risk of running at a loss.
The next halving, expected in late 2028 at block height 4,406,400, will cut rewards from 1.5625 $ZEC to 0.78125 $ZEC. That event is already a factor in how serious mining operations plan hardware investment cycles, since return on investment timelines shrink as rewards compress.
Is Zcash Mining Still Relevant in 2026?
As of mid-2026, $ZEC mining remains viable for operations with access to low-cost electricity and current-generation ASIC hardware. The regulatory picture for privacy coins has also clarified somewhat. In June 2026, ZODL, the commercial entity formed from the original Electric Coin Company team with $25 million in seed funding from Paradigm, a16z, and Coinbase Ventures, confirmed that Zcash is not banned under the EU’s MiCA rules, though some exchanges may restrict shielded transaction deposits for compliance reasons.
The core mining incentive structure remains intact. Miners receive 80% of each block reward, network difficulty adjusts automatically based on total hash rate, and the PoW layer continues to secure the chain. The PoS transition under development, code-named Crosslink, is designed to add a finality layer rather than replace PoW outright in the near term.
Conclusion
The November 2024 halving cut Zcash’s block reward to 1.5625 $ZEC, split 80% to miners, 8% to community grants, and 12% to a governance lockbox. With 16.7 million of 21 million $ZEC already in circulation, the pace of new supply is slowing on a fixed schedule.
Miner revenue depends on ASIC efficiency, electricity cost, and whether $ZEC‘s price keeps pace with falling rewards. The next halving in late 2028 will apply further pressure to both figures. The scarcity model Zcash inherited from Bitcoin is working as designed: issuance slows, supply tightens, and mining economics grow increasingly dependent on price rather than volume of coins earned.
