Blockchain-Based Exchange Place: Genericity vs Performance

The traditional exchange places have been overwhelmed by several challenges, including counterparty risk, and lack of consumer trust. Platforms based on blockchain technology have emerged to address these challenges by improving visibility and ensuring the execution of contracts. In this paper, we propose (ODEP), for Orange Decentralized Exchange Place. It allows to pool functionalities for sharing resources of different kinds while preserving the overall performance in terms of Transactions Per Second (TPS) and used gas. For that, we proposed an on-chain/off-chain approach consolidated with ODEPv2 and that consists of limiting the volume of data stored in blockchain. The comparison with ODEPv1, where all data are stored on blockchain, has demonstrated the effectiveness of our approach with an enhancement of 40% on used gas. Moreover, we propose the overall architecture to the simple adaptation of ODEP with different contexts.
