ZIP 235 ↗

Held · by consensus

Consensus state

Nodes track the amount as part of consensus and leave it out of issued supply. It started at 368.5844552 ZEC, the subsidy and fees that coinbase transactions left unclaimed before NU6.

ZIP 237 ↗

Out · through the subsidy

Block 8,939,664

From that block on, every block adds 1375 / 10¹⁰ of the balance to its scheduled subsidy, rounded up: about half the balance each halving period. At today's balance that would be 0.00005201 ZEC a block.

ZIP 237 ↗ · ZIP 259 ↗

Not deployed: ZIP 233 ↗, a transaction field for voluntary removals, is a draft and was left out of NU7. ZIP 234 ↗, issuance smoothing, was replaced by ZIP 237, which keeps the halvings.
