Considering the ongoing digital transformation in Orange ecosystem, different marketplaces may co-exist together for different use cases: Energy, Telecom connectivity resources, IoT (Internet of Things) and more. To allow such exchanging platform to be independent from specificities behind any use case, we present in this paper the Orange exchange place: a Blockchain-based generic exchange platform of goods and services. This exchange place exposes generic/common transactions as an On-chain digitally executed smart contracts. To emphasize the generic aspect of the exchange place, we separate the specific aspect of the use cases and encapsulate it as Off-chain modules (out of Blockchain). To enable the simple adaptation of the exchange place to different contexts, we propose a configurable exchange place data model. Therefore, the paper demonstrates how Blockchain technology, the On-chain/Off-chain approach and the configurable data model come together to design a generic distributed exchange place. |
