Polkadot upgrades token model, with DOT maximum supply set at 2.1 billion coins

Polkadot announced on the X platform that the token issuance model upgrade has officially taken effect on March 14th. This update sets the maximum supply of DOT at 2.1 billion tokens. Currently, about 80% of the tokens have been issued, and the issuance rate has been reduced by about 53% at once, with plans to gradually decrease in the future. The adjustment is proposed by the community and approved through the OpenGov governance mechanism, aiming to maintain the network incentive mechanism while limiting the long-term issuance scale, providing a more transparent and predictable token issuance path.
