Issuance refers to an official process characterized by the production or creation of something as well as its distribution to approved receivers. The term has wide-range usage and is commonly employed in law, publishing, medicine, commerce, and finance. In crypto space, the term has a more specific usage which involves the different processes involved in generating new cryptocurrencies and allocating them to users.
In the world of blockchain networks, issuance mostly occurs in the form of mining and Initial Coin Offerings (ICOs). In both cases, cryptos leave the system and end up as assets of traders and investors.
