Polkadot upgrades token model, sets DOT maximum supply at 2.1 billion

Polkadot announced on the X platform that its token issuance model upgrade officially took effect on March 14. This update sets the maximum supply of DOT at 2.1 billions, with approximately 80% of tokens already issued. The issuance rate has been reduced by about 53% in a one-off adjustment, and there are plans to gradually decrease it further in the future. The adjustment was proposed by the community and approved through the OpenGov governance mechanism, aiming to maintain the network incentive mechanism while limiting long-term issuance scale, providing a more transparent and predictable token issuance path.
