Interopérabilité des Systèmes Blockchains

Abstract : Blockchains are a disruptive technology. They enable an ecosystem for decentralized applications with interesting properties: transaction transparency, application auditability or censorship resistance. It has applications in various fields, such as finance, healthcare or video games. It has evolved a lot since its creation in 2008, and presents numerous perspectives. However, the field faces many challenges, in particular a lack of interoperability at several levels: between projects on a same Blockchain, between different Blockchains, or between Blockchains and other systems. One important aspect of Blockchain systems interoperability is semantic interoperability. It relies on formal definitions of the related concepts. Another challenge is the design of decentralized Blockchain applications. These applications integrate Blockchain technology, but also other services that satisfy the constraints of the application that Blockchain is not suitable for. However, it is complex to choose the most suited Blockchain service for a given application. With this PhD work, we propose a framework that can improve interoperability for decentralized Blockchain applications. We achieve this with the design of a methodology and a Blockchain ontology that help formalize the concepts related to an application. This framework is validated in the context of Blockchain video game development. It is a complex use case, as it needs to share storage intensive data and satisfy the latency constraints.
