Polkadot DAO Passes Proposal #1710, Capping DOT Supply at 21 Billion with 81% Support to Reduce Emissions

The Polkadot DAO approved Proposal #1710 on September 15, with roughly 81% support, instituting a fixed DOT token supply cap of 21 billion. The governance decision formalizes a change to Polkadot’s monetary policy via on‑chain voting and will replace the protocol’s prior uncapped issuance framework.

Under the new parameters, the existing uncapped model that minted about 1.2 billion DOT per year will be superseded by an adjusted issuance schedule that reduces token emissions through staged decreases to DOT issuance every two years. Market participants and validators should monitor governance updates for the precise emission curve and implementation timeline.
