Module formulas

Defines constants and formulas which are used in pchain_runtime.

For example, they are

• the portion of gas fee burning into Tresury account (TREASURY_CUT_OF_BASE_FEE)
• the calculation of issuance to reward the network (issuance_reward)
• issuance rate (ISSUANCE_RATE_FACTORS)
• calculation of pool reward and stake reward

Constants

ISSUANCE_RATE_FACTORS

0.85 ^ (n / 365) (and then multply by 10000 to make it integer)

ISSUANCE_STABLE_EPOCH

Number of epoch to reach for applying a constant issurance rate in reward calculation

TOTAL_BASE_FEE

denominator of Treasury cut of Base fee

TREASURY_CUT_OF_BASE_FEE

Send 20% of gas to Treasury

Functions

issuance_reward

Calculate issuance reward at particular epoch.

pool_reward

Calculate reward of a pool. It is fraction of the pool power to network power, and block performance. Baseline is calculated by: number of blocks per term / number of validators.

stake_reward

Return reward to the stakes and commission_fee.
