Fields

global_memory_per_byte_cost: InternalGasUnits<u64>

The cost per-byte read from global storage.

global_memory_per_byte_write_cost: InternalGasUnits<u64>

The cost per-byte written to storage.

min_transaction_gas_units: InternalGasUnits<u64>

The flat minimum amount of gas required for any transaction. Charged at the start of execution.

large_transaction_cutoff: AbstractMemorySize<u64>

Any transaction over this size will be charged an additional amount per byte.

intrinsic_gas_per_byte: InternalGasUnits<u64>

The units of gas that to be charged per byte over the large_transaction_cutoff in addition to min_transaction_gas_units for transactions whose size exceeds large_transaction_cutoff.

maximum_number_of_gas_units: GasUnits<u64>

~5 microseconds should equal one unit of computational gas. We bound the maximum computational time of any given transaction at roughly 20 seconds. We want this number and MAX_PRICE_PER_GAS_UNIT to always satisfy the inequality that MAXIMUM_NUMBER_OF_GAS_UNITS * MAX_PRICE_PER_GAS_UNIT < min(u64::MAX, GasUnits::MAX) NB: The bound is set quite high since custom scripts aren’t allowed except from predefined and vetted senders.

min_price_per_gas_unit: GasPrice<u64>

The minimum gas price that a transaction can be submitted with.

max_price_per_gas_unit: GasPrice<u64>

The maximum gas unit price that a transaction can be submitted with.

max_transaction_size_in_bytes: u64

gas_unit_scaling_factor: u64

default_account_size: AbstractMemorySize<u64>
