Emission Schedule
In simple terms
The schedule that determines how many new coins get created and when. Think of it like a recipe that decides how much new money a cryptocurrency system prints over time.
Definition
The rate and timeline for creating new tokens.
In depth
The predetermined protocol rules that govern the creation and distribution of new tokens over time, typically implemented through block rewards given to validators or miners. Emission schedules define parameters such as initial supply, halving events, maximum supply caps, and inflation rates, ensuring predictable monetary policy without reliance on central authorities. Bitcoin, for example, has a fixed emission schedule where block rewards halve approximately every four years until reaching its 21 million coin maximum, while other networks may employ alternative mechanisms like linear decay or perpetual inflation to incentivize network participation.
How does Emission Schedule work?
An emission schedule is a set of rules, usually written into protocol code or a token contract, that specifies how many new tokens are created in each period and where they go. Network nodes enforce those rules when validating blocks, so no participant can mint extra units. Bitcoin's schedule pays a block reward that halves every 210,000 blocks, roughly every four years, tapering issuance toward its 21 million cap. Other projects release tokens on a calendar, unlocking allocations for a treasury, contributors, and staking rewards. Because the rules are public, anyone can compute future supply.
An example
Illustrative figures: a project mints 100 million tokens at launch and schedules 10 million more each year for five years, all paid out as staking rewards. Circulating supply rises to 110 million after year one and 150 million after year five. Someone holding 1 million tokens starts with 1 percent of supply. If they earn none of the new tokens, that share falls to about 0.67 percent by the end of year five.
Figures are illustrative only.
What beginners get wrong
- Reading total supply as the number of tokens actually trading; circulating supply is often much smaller, and the difference is future emissions.
- Many schedules are not fixed. Check whether governance or an admin key can change issuance before treating a published curve as permanent.
- A hard supply cap does not mean low issuance today; a capped token can still emit a large share of its supply early on.
- New tokens paid to stakers dilute holders who do not stake, even though the number of tokens in their wallet never changes.
