The Polkadot DAO community $DOT approved a key change in tokenomics, introducing a strict cap on the total token supply at 2.1 billion DOT. The corresponding decision was made based on the results of a referendum vote supported by 81% of participants.

Prior to this, the asset's issuance was unlimited: 120 million DOT was released each year, and by 2040, about 3.4 billion DOT could have been in circulation. The new model involves a gradual reduction in coin issuance every two years.
