Polkadot announced that its tokenomics upgrade officially launched on March 14 (Pi Day). The protocol upgrade introduces two core initiatives: first, establishing a maximum supply cap of 2.1 billion DOT (approximately 80% of which has already been issued); second, reducing DOT's emissions rate by approximately 53% starting March 14, with plans for further reductions in the future. The official team stated that these changes were proposed by the community and approved through OpenGov, aimed at constraining long-term issuance, maintaining incentive mechanisms, and providing a transparent and predictable issuance schedule.
