Track Zcash issued supply, the observed block height and how much ZEC is held in shielded pools. All snapshot values below share one dated source observation. Explore the historical charts, the block-based halving schedule and the network upgrade timeline without treating pool balances as a count of users or transactions.

Next Halving
Block 4,406,400
901,645 blocks after the observed height · reference subsidy schedule, not an exact calendar forecast.
Configured mainnet boundaries from saved protocol sources. An observed height past a boundary is not an independent verification of its activation block. Calendar dates are shown only when recorded.
Mainnet upgrade heights and documented date availability
The latest source-reported issued supply is 16,965,812.6655 ZEC, observed at 2026-10-03T09:53:43.533Z. A market provider’s circulating supply can use a different definition.
When is the next Zcash halving?
Under the referenced subsidy schedule, the next boundary after the observed height is block 4,406,400. The exact calendar date depends on block production; it is not fixed by the height alone.
What percentage of ZEC is shielded?
The latest observed share is 29.09%, calculated as Sprout + Sapling + Orchard + Ironwood divided by source-reported issued supply from the same observation.
What is Ironwood?
Ironwood is a distinct value-pool label in the network data and upgrade documents. Orchard protocol support and a balance in the older Orchard pool are different concepts. Read the Ironwood guide for the applicable rules and migration context.
How often does Zcash upgrade the network?
There is no fixed annual schedule. Upgrades are specified with consensus changes and activation heights. Proposal status, software support and an observed activation block are separate records.
Issued supply and shielded balances use the same normalized source observation. Shielded total includes Sprout; charts of three pools do not silently redefine that total. ZecStats is a third-party provider, not this site's independently run node.
