Polkadot upgrades its issuance model: the DOT issuance rate is reduced by approximately 53%, and the maximum supply is set at 2.1 billion tokens.

PANews reported on March 14th that Polkadot announced on its X platform that its token issuance model upgrade officially took effect on March 14th (Pi Day). This protocol update introduces several key adjustments, including setting the maximum supply of the native token DOT at 2.1 billion. Currently, approximately 80% of the tokens have already been issued. The issuance rate of DOT will also be reduced by approximately 53% on March 14th, with plans to continue gradually decreasing it in the future. These adjustments were reportedly proposed by the community and approved through the OpenGov governance mechanism, aiming to limit the long-term issuance scale while maintaining network incentives and providing the market with a more transparent and predictable token issuance path.
