Function

The Minting Module plays a crucial role in the blockchain ecosystem, tasked with regulating the issuance of tokens to validators. This ensures the network's ongoing stability and viability. The module operates consistently, adjusting key parameters with each block to maintain a balanced token supply.

Calculation of Inflation

The method for determining the inflation rate is outlined in the AXONE Whitepaper - Token Model.

Per-Block Token Generation

Given the annual inflation rate, the Minting Module calculates the exact amount of tokens to be generated for each block, based on the total number of blocks in a year.

mint/v1beta1/mint.proto

Minter

Minter holds the state of minting within the blockchain.

Field	Type	Label	Description
inflation	string		Current annual inflation rate.
annual_provisions	string		Current annual anticipated provisions.

Params

Params defines the parameters for the mint module.

Field	Type	Label	Description
mint_denom	string		Denomination of the coin to be minted.
inflation_coef	string		Annual inflation coefficient, influencing the inflation rate based on the bonded ratio. Values range from 0 to 1, with higher values indicating higher inflation.
blocks_per_year	uint64		Estimated number of blocks per year.
inflation_max	string		Maximum annual inflation rate.
inflation_min	string		Minimum annual inflation rate.
