Grin Emission & Supply
Grin has one of the simplest monetary policies in crypto: a flat reward of 60 ツ per block, one block a minute — exactly 1 ツ every second, forever. No halvening, no premine, no founder reward.

Verify it yourself
There is nothing to trust here — circulating supply is just height × 60. Pick any block height and check:
= — ツ
Because new supply is fixed while total supply keeps growing, Grin's percentage
inflation falls every year — asymptotically toward zero — even though the absolute
60 ツ/block never changes. That is the deliberate design: predictable issuance that quietly
disinflates without a cliff, a cap, or a founder's cut.
How Grin compares
| Asset | New supply | Supply cap | Schedule |
|---|---|---|---|
| Grin | Constant · 1 ツ/s | None | Linear, forever |
| Bitcoin | Halves ~4 yrs | 21M | Geometric decay |
| Gold | ~1.5% / yr | Unknown | Mining-driven |
| Fiat | Discretionary | None | Central-bank policy |
Why constant emission?
- Fairness across time. A flat reward means someone who starts mining today faces the same issuance as a day-one miner — no early-adopter windfall baked into the schedule.
- Predictability. No halvening events, no supply shocks. The heartbeat is literally one coin per second, so anyone can compute total supply for any point in time.
- Disinflation without a cap. Percentage inflation trends toward zero as the base grows, so Grin tightens over time without ever hitting a hard ceiling that ends block rewards.
- Security funding forever. Because rewards never stop, miners are always paid by issuance — the network never has to rely solely on fees for its security budget.
