The rate at which new cryptocurrency coins are created and distributed.
Emission in the context of cryptocurrencies refers to the process by which new coins are created and distributed. This can be through mining, staking, or as rewards for various forms of participation in the cryptocurrency's ecosystem. The rate of emission and the total supply limit (if any) are usually set at the time the cryptocurrency is created and can play a significant role in the coin's market dynamics.
The Bitcoin emission rate is halved approximately every four years in an event known as the 'halvening'.
