Polkadot's economic model is set to follow a clear and predictable long-term path following the approval of the WFC (Hard Pressure) proposal. This development marks the first time Polkadot has established such a defined trajectory. The core elements of this path include a total supply cap of 2.1 billion DOT, a biennial reduction in annual issuance, and a decrease rate of 13.14% of the remaining issuance each time. Under the Hard Pressure model, starting from March 14, 2026, Polkadot's annual issuance will officially begin to decline, with the first reduction corresponding to an annual inflation rate of approximately 3.11%.
