Techub News report: Polkadot announced on the X platform that its token issuance model upgrade will take effect on March 14th. This protocol update will introduce several key adjustments, including setting the maximum supply of native token DOT at 2.1 billion, with approximately 80% of tokens already issued. The DOT issuance rate will be reduced by approximately 53% on March 14th in a single adjustment and is planned to continue declining gradually in the future. The aforementioned adjustments were proposed by the community and approved through the OpenGov governance mechanism, aiming to limit long-term issuance scale while maintaining network incentive mechanisms, and provide the market with a more transparent and predictable token issuance path. #Gate广场AI测评官
