What are gas fees, really?
Every transaction on a blockchain network like Base or Ethereum requires thousands of computers worldwide (validator nodes) to execute the operation, verify it, and permanently store it on a shared public ledger. This computational work consumes real electricity and computing resources, and a small fee - called gas - is paid for it. The fee does not go to a single 'creditor'; it is distributed among those who run and secure the network.
The core difference between gas and riba
Riba in Islamic jurisprudence is a conditional increase on the principal of a cash loan charged purely for the passage of time, with no real work or service behind it. Gas fees, by contrast, are an ijarah-style wage: payment for real computational work - executing the operation, verifying it, and recording it permanently in a block. It compensates tangible work happening in that very moment, not an increase on a sum lent over time. Islamic law permits charging a fee for real work or service (ijarah), and prohibits only a conditional increase on a cash loan tied to a deferred term.
Why there is no loan in a gas payment
Riba requires a creditor, a debtor, a deferred repayment term, and a conditional increase. In paying gas, no party lends you money to repay later with extra; you pay immediately for a service rendered immediately - just like paying for electricity or express delivery. The absence of the pillars of a loan (debt and deferred term) removes the transaction entirely from the scope of prohibited riba.
Do gas fees fluctuate? Why that matters religiously
Yes, fees rise when the network is congested and fall when it is quiet, similar to surge pricing for transport during peak hours. This fluctuation reflects genuine market supply and demand for limited computing resources, not a usurious increase on a debt. Estimates of how much networks collectively spend on such fees vary widely, and no single definitive figure can be generalized - but the jurisprudential principle holds regardless of the amount: what matters is the true nature of the contract, not the fee's size.
How does Qist apply this?
The Qist protocol is built on the Base network, one of the cheapest blockchains in terms of gas fees compared to Ethereum mainnet, reducing the burden on users when executing Murabahah contracts and paying installments. Qist's own fee is entirely separate from gas: Qist charges a 2% protocol operating fee, payment is in the stable USDC currency, the seller genuinely owns the asset before the sale, and there is no riba or gharar anywhere in the process.
