BenFen’s gas fee mechanism is carefully engineered to minimize transaction costs and optimize user experience.
Gas Pricing Formula
The total gas fee paid by users is calculated based on computation and storage costs, minus any storage rebate:
Net_gas_fees = (computation_units * reference_gas_price) + (storage_units * storage_price) - storage_rebate-
Reference Gas Price Proposed by validators at the beginning of each Epoch and dynamically determined using the 2/3 weighted median, ensuring gas prices reflect market conditions.
-
Storage Rebate When a transaction deletes previously stored data, the system refunds a portion of the storage cost, encouraging efficient use of on-chain storage.
Gas Payment Options
BenFen natively supports stablecoin payment for Gas fees：
-
BFC: the native payment token.
-
Stablecoins: Users can directly use BUSD to pay for Gas. The system will automatically exchange it for BFC to complete the payment after charging a very small percentage of transaction wear and tear fees through built-in services.
-
User-Issued Tokens: With community governance approval, project-issued tokens may be added to the gas payment whitelist.
