What is cryptocurrency emission?
Understanding Cryptocurrency Emission in the Digital Economy
Cryptocurrency emission refers to the creation of new coins or tokens over time. In simple terms, it’s how much new cryptocurrency is being added into circulation — similar to how central banks print new money.
In most blockchain systems, coins are emitted as part of block rewards — miners or validators receive new tokens for adding blocks to the blockchain. This emission rate plays a crucial role in monetary policy and helps define the total supply and long-term value of a cryptocurrency.
Emission vs. Inflation
While emission measures the absolute value of the supply change, inflation expresses the percentage change in total supply over time. In other words:
- Emission = Value of the change in supply over a given period.
- Inflation = How much the supply grew, proportionally.
How to Calculate Cryptocurrency Emission
To calculate emission over a given period (e.g., 24 hours, 30 days, 1 year), subtract the starting circulating supply from the ending supply and multiply by price:
$$
\text{Emission} = (S_{\text{end}} – S_{\text{start}}) * \text{price}
$$
- \(S_{\text{start}}\) is the circulating supply at the beginning of the period.
- \(S_{\text{end}}\) is the circulating supply at the end of the period.
If the \(S_{\text{start}}\) is smaller than the \(S_{\text{end}}\), the coin is deflationary and has negative emission. That means, that there are coins being removed from the circulating supply.
*Disclaimer – in reality the result of this calculation has to be averaged, in order for the data to be usable. Read more about SMA and data smoothening here.
Emission Over Timeframes
You can calculate average emission per day, month, or year depending on your data.
$$
\text{Daily Emission} = \frac{S_{\text{end}} – S_{\text{start}}}{T} * \text{price}
$$
Where:
\( T \) is the number of days (or years) the data covers.
Example: If the period covers 30 days, then
\(T=30T\)
Real-World ExampleSstart
Let’s say a cryptocurrency had:
- \(S_{\text{start}}\) = 18 000 000 coins
- \(S_{\text{start}}\) = 18 100 000 coins
- \(\text{price}\) = 5$
- Time period \(\text{T}\) = 30 days
$$
\text{Emission} = (18,100,000 – 18,000,000) * 5 = 500,000
$$
$$
\text{Daily Emission} = \frac{500,000}{30} \approx 1,666.66
$$
Why Emission Matters
Understanding emission helps you:
- Predict future supply growth
- Evaluate scarcity and inflation risk
- Compare the tokenomics of different coins
- Make smarter long-term investment decisions
Coins with high emissions may dilute your holdings unless offset by demand or burning mechanisms. On the other hand, coins with low or fixed emissions (like Bitcoin) are often seen as deflationary and more scarce.
