The FAME Federated Data Marketplace utilizes blockchain in order to immutably record data asset offerings by data providers and purchases by customers. FAME supports Pay-As-You-Go (PAYG), Pay-As-You-Use (PAYU) and Subscription (SUBS) models for data access purchases.
The two most critical functions in the blockchain-based Trading Management system are the data asset offering creation function, used by the data providers, and the purchase asset offering function, used by the customers.
As the marketplace evolves, the number of data providers, data assets, and users is expected to increase substantially. The key question is whether the Trading Management system can continue to function robustly (i.e., without failures) and efficiently (i.e., with non-growing Ethereum gas consumption costs) under these scaling conditions. To address this, scalability testing is performed.
The scalability tests demonstrate that the Trading Management (TM) system maintains both robust and efficient performance as the number of data providers, assets, and users increases. Despite the growth in transaction volume, the average gas costs for critical smart contract functions (including creating data asset offering and processing PAYG, PAYU, SUBS purchases) remain relatively stable, indicating efficiency and no performance degradation. These results confirm the ability of TM smart contracts to handle both moderate and large-scale usages efficiently without operational failures.
