Events¶

ForcedInflationRecalculation¶

Inflation recalculation has been forced.

Attributes¶

Name	Type	Composition
config	`InflationConfiguration`	`{'recalculation_era': 'u32', 'issuance_safety_cap': 'u128', 'collator_reward_per_block': 'u128', 'treasury_reward_per_block': 'u128', 'dapp_reward_pool_per_era': 'u128', 'base_staker_reward_pool_per_era': 'u128', 'adjustable_staker_reward_pool_per_era': 'u128', 'bonus_reward_pool_per_period': 'u128', 'ideal_staking_rate': 'u64'}`

InflationConfigurationForceChanged¶

Inflation configuration has been force changed. This will have an immediate effect from this block.

Attributes¶

Name	Type	Composition
config	`InflationConfiguration`	`{'recalculation_era': 'u32', 'issuance_safety_cap': 'u128', 'collator_reward_per_block': 'u128', 'treasury_reward_per_block': 'u128', 'dapp_reward_pool_per_era': 'u128', 'base_staker_reward_pool_per_era': 'u128', 'adjustable_staker_reward_pool_per_era': 'u128', 'bonus_reward_pool_per_period': 'u128', 'ideal_staking_rate': 'u64'}`

InflationParametersForceChanged¶

Inflation parameters have been force changed. This will have effect on the next inflation recalculation.

Attributes¶

No attributes

NewInflationConfiguration¶

New inflation configuration has been set.

Attributes¶

Name	Type	Composition
config	`InflationConfiguration`	`{'recalculation_era': 'u32', 'issuance_safety_cap': 'u128', 'collator_reward_per_block': 'u128', 'treasury_reward_per_block': 'u128', 'dapp_reward_pool_per_era': 'u128', 'base_staker_reward_pool_per_era': 'u128', 'adjustable_staker_reward_pool_per_era': 'u128', 'bonus_reward_pool_per_period': 'u128', 'ideal_staking_rate': 'u64'}`

Storage functions¶

ActiveInflationConfig¶

Active inflation configuration parameters. They describe current rewards, when inflation needs to be recalculated, etc.

Python¶

result = substrate.query(
    'Inflation', 'ActiveInflationConfig', []
)

Return value¶

{
    'adjustable_staker_reward_pool_per_era': 'u128',
    'base_staker_reward_pool_per_era': 'u128',
    'bonus_reward_pool_per_period': 'u128',
    'collator_reward_per_block': 'u128',
    'dapp_reward_pool_per_era': 'u128',
    'ideal_staking_rate': 'u64',
    'issuance_safety_cap': 'u128',
    'recalculation_era': 'u32',
    'treasury_reward_per_block': 'u128',
}

DoRecalculation¶

Flag indicating whether on the first possible opportunity, recalculation of the inflation config should be done.

Python¶

result = substrate.query(
    'Inflation', 'DoRecalculation', []
)

Return value¶

'u32'

InflationParams¶

Static inflation parameters - used to calculate active inflation configuration at certain points in time.

Python¶

result = substrate.query(
    'Inflation', 'InflationParams', []
)

Return value¶

{
    'adjustable_stakers_part': 'u64',
    'base_stakers_part': 'u64',
    'bonus_part': 'u64',
    'collators_part': 'u64',
    'dapps_part': 'u64',
    'ideal_staking_rate': 'u64',
    'max_inflation_rate': 'u64',
    'treasury_part': 'u64',
}

Errors¶

InvalidInflationParameters¶

Sum of all parts must be one whole (100%).
