The new inflation parameters approved by the Polkadot community are now running on the Westend testnet. So far, everything is performing as expected, with a gradual decrease in inflation and fixed treasury income. A root referendum to implement the changes will be initiated as soon as the Polkadot Fellows have finished their checks.
With the passing of Referendum 1139, the Polkadot community has indicated a sentiment for reducing inflation to 8%, decreasing linearly over time. Jonas Gehrlein (Web3 Foundation) has indicated that he will initiate a Root referendum to implement the changes after the enactment of runtime 1.3.3.
A fourth proposal for adjusting inflation parameters has been submitted on the OpenGov Wish for Change track. A user by the name of Dobby proposes an inflation rate of 5% rate, with a constant 15% of inflation going to the treasury. Dobby appears to be waiting for a generous donor to place the 20,000 DOT decision deposit.
Jonas Gehrlein (Web 3 Foundation) has initiated three concurrent referenda on the OpenGov Wish for Change track, with the intention of forming a consensus on Polkadot inflation parameters. Referendum 1137 proposes maintaining a 10% rate, with a constant 15% of inflation going to the treasury. Referendum 1138 proposes an 8% rate, with a constant 15% of inflation going to the treasury. Referendum 1139 proposes linear inflation at a fixed number of tokens (potentially 8% of the current supply), and 15% of inflation going to the treasury. This would result in the rate of inflation lowering over time.
