Polkadot upgrades its token issuance model, setting the maximum supply of DOT at 2.1 billions.

On March 14, Polkadot announced on the X platform that its token issuance model upgrade has officially taken effect, setting the maximum supply of DOT at 2.1 billions, with approximately 80% already issued. The DOT issuance rate was reduced by about 53% in a one-time adjustment on March 14, and will gradually decrease in the future. The adjustment was proposed by the community and approved through the OpenGov governance mechanism, aiming to maintain the network incentive mechanism and limit long-term issuance scale.
