Ontologias para o ecossistema de finanças descentralizadas: estrutura e interoperabilidade no ecossistema blockchain

Abstract

Decentralized Finance (DeFi) emerges as a growing field in the blockchain environment, as it proposes transparent and automated transactions without intermediaries. This article aims to present the development of a comprehensive ontology for the Decentralized Finance ecosystem, reusing existing ontologies from specific contexts. The methodology includes a literature review to specify concepts and relationships in Decentralized Finance, identification and analysis of current ontologies related to blockchain and Decentralized Finance, followed by mapping these ontologies to find gaps and creating a new ontology. Results show the current version of the ontology, based on a multilayer architecture and its business models, as well as on concepts and relationships of the DeFi ecosystem most prominent in the literature. Analysis of existing ontologies from specific parts of the ecosystem reveals that, although there is already a shift in the representation of concepts related to blockchain, there is a gap in the complete formalization. The proposed ontology aims to standardize terminologies, reduce ambiguities, promote interoperability and facilitate communication between users and systems, contributing to the structuring and the development of research and applications in DeFi.
