The Polkadot upgrade issuance model sets the maximum supply of DOT at 2.1 billion

On March 14, Polkadot announced on the X platform that its token issuance model upgrade officially took effect on March 14 (Pi Day). This protocol update will introduce several key adjustments, including setting the maximum supply of the native token DOT at 2.1 billion, with about 80% of the tokens already issued. Meanwhile, the issuance rate of DOT will be reduced by approximately 53% in a one-time adjustment on March 14, with plans to continue gradually lowering it in the future. It is reported that the above adjustments were proposed by the community and approved through the OpenGov governance mechanism, aiming to maintain the network's incentive mechanism while limiting long-term issuance scale and providing a more transparent and predictable token issuance path for the market.
