Sui maintains gas stability under heavy network load through several design choices that aim to balance efficiency, scalability, and predictability:

1. Dynamic Gas Pricing: Sui uses dynamic gas pricing that adjusts based on network demand. When the network is under heavy load, the gas price increases to reflect the higher demand for resources. This ensures that transactions are prioritized based on their willingness to pay for computation and storage, preventing the network from being overwhelmed by low-priority transactions.

2. Object-Centric Design: By utilizing an object-centric model, where each object can be independently modified, Sui allows for better parallelization of transactions. This reduces the chance of bottlenecks and ensures that not all transactions are competing for the same resources, which helps maintain stable gas costs even when the network is busy.

3. Parallel Execution: Sui processes transactions in parallel, which improves throughput and reduces delays under heavy loads. This parallelism means that transactions affecting different objects or independent state can be processed simultaneously, easing the load on individual validators and preventing gas prices from spiking due to congestion.

4. Transaction Prioritization: Sui’s consensus mechanism ensures that transactions with higher fees are prioritized during periods of heavy load. This helps prevent the network from being congested by lower-value transactions, keeping gas prices stable and predictable.

5. Efficient Block Processing: Sui’s block processing is designed to be fast and scalable. Validators can process more transactions per block, which helps reduce the impact of network congestion and maintain gas price stability.

In essence, Sui leverages a combination of dynamic pricing, parallelization, and efficient transaction processing to maintain gas stability, even under heavy load conditions. This approach helps prevent gas spikes and ensures a smooth user experience.

ach transaction pays a predictable base fee for computation and storage, and validators compete in an auction-like system that sets reference prices fairly. Since transactions only touch specific objects, Sui can run many in parallel, which avoids bottlenecks that normally drive up gas on other chains. This design means that even when activity spikes, gas prices stay relatively stable and users get

Gas prices adjust dynamically based on network demand.

Parallel execution of independent objects reduces congestion.

Validators prioritize higher-fee transactions during busy times.

Gas estimation tools help users avoid surprises.

Gas fees deter spam, keeping the network healthy.

You get gas stability on Sui because it uses a unique gas price mechanism and parallel execution to handle high traffic smoothly. Each transaction has a predictable base fee that covers computation and storage, while validators set reference prices through a fair-market process instead of sudden fee spikes. Since Sui processes transactions in parallel as long as they touch different objects, congestion is reduced, which prevents gas wars. The system also uses storage fund mechanics so long-term costs are balanced and not just pushed onto short-term users. This keeps gas fees relatively stable, even when demand is high.

You benefit from gas stability on Sui because the network separates storage gas from computation gas and uses a storage fund to balance long-term costs. Even when demand spikes, the system adjusts fees through market-driven mechanisms so you don’t face sudden unpredictable jumps in transaction costs. The parallel transaction execution also helps reduce congestion since multiple transactions can run simultaneously, which keeps gas prices more stable compared to blockchains that queue transactions sequentially.
